First Embodiment

Hereinafter, the tongue 100 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG.

FIG. 1 is an exploded perspective view of a gripper 100 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the gripper 100 illustrated in FIG. 4 is a view illustrating a state in which the elastic force of the elastic member 150 is adjusted while the elastic member 150 is being pressed by the rotation of the pressing member 140. FIG. FIG.

1 to 4, a forceps 100 according to an embodiment of the present invention includes a first member 110, a second member 120, a pressing member 140, and an elastic member 150 do.

The pressing member 140 is screwed to the second member 120 and moves in the direction of the elastic member 150 by the rotation of the pressing member 140, And presses one end thereof out of the member (150). 4, the elastic member 150 compressed by the pressing member 140 resiliently presses the end portion 111 of the first member 110 and the end portion 121 of the second member 120 The force is increased. Accordingly, the force of gripping the object (not shown) by the friction rubber 116 or 132 corresponding to the other end of the gripper 100 increases. As described above, the tongue 100 according to the present embodiment can adjust the elastic force of the elastic member 150 by the rotation of the pressing member 140, thereby adjusting the pressing force of the tongue 100.

The first member 110, together with the second member 120, forms a portion that grips the gripper 110. The first member 110 has a rectangular shape and a first penetrating portion 114 is formed at the center thereof. The first connection parts 112 are respectively protruded downward on the right and left side surfaces of the first member 110 and the friction rubber 116 is provided on the inner side of the end parts thereof. A first fixing hole 118 is formed in the inner surface of the first member 110 to receive the end of the first supporting portion 154 of the elastic member 150.

The first member (110) rotatably engages with the second member (120). A pressing member 140 and an elastic member 150 are provided in the first member 110 and the second member 120. The elastic member 150 presses the end portion 111 of the first member 110 upward and presses the end portion 121 of the second member 120 downward so that the portion where the friction rubber 116, . The pressing member 140 serves to adjust the elastic force of the elastic member 150.

The first connection part 112 is rotatably coupled to the rotation shaft 128 together with the second connection part 122. 1 to 4 illustrate that the first connection part 112 is disposed outside the second connection part 122 when the first member 110 and the second member 120 are coupled.

The first penetrating portion 114 is located between the first connecting portions 112 and has a rectangular shape. A part of the pressing member 140 protrudes to the outside of the first member 110 through the first penetrating portion 114. [ No thread is formed on the inner circumferential surface of the first penetration portion 114. The pressing member 140 can freely rotate with respect to the first member 110 because the circumferential surface of the pressing member 140 is not screwed with the inner circumferential surface of the first penetrating portion 114. [

A friction rubber 116 is provided inside the other end of the first member 110. The friction rubber 116 increases the frictional force with respect to the object to be gripped so that the object does not fall off easily.

The first fixing hole 118 is formed on the inner surface of the first member 110 and the end of the first supporting portion 154 of the elastic member 150 is inserted. The first support portion 154 of the elastic member 150 can be inserted into the first fixing hole 118 because the end portion thereof is vertically bent. As a result, even if the pressing member 140 presses the elastic member 150 in the lateral direction, the first supporting portion 154 does not move.

The second member 120 includes a second penetration portion 124 formed corresponding to the first penetration portion 114, a second connection portion 122 for coupling with the first member 110, an elastic member 150 And a second fixing hole 134 into which the end of the second supporting portion 156 of the second fixing portion 156 is inserted.

The second penetrating portion 124 is located between the pair of second connection portions 122 and has a rectangular shape. On the inner peripheral surface of the second through hole 124, an inner thread 126 is formed in the longitudinal direction of the rotary shaft 128. The inner thread 126 is threadably engaged with an outer thread 144 formed on the outer periphery of the urging member 140 so that the urging member 140 can be moved laterally along the inner thread 126.

An inner thread 126 is formed in the second penetrating portion 124 on a pair of inner surfaces facing each other with respect to the longitudinal direction of the second member 120. The pair of inner surfaces formed with the inner thread 126 in the second through hole 124 have an arc shape as shown in FIG. 3 and are formed symmetrically.

The second connection portion 122 is formed adjacent to the second penetration portion 124 to form a pair of left and right. A rotation shaft 128 is inserted into the pair of second connection portions 122.

The second fixing hole 134 is formed on the inner surface of the second member 120 and the end of the second supporting portion 156 of the elastic member 150 is inserted. The second support portion 156 of the elastic member 150 can be inserted into the second fixing hole 134 because the end portion thereof is vertically bent. Similarly to the first fixing hole 118, the second fixing hole 134 also prevents the second supporting portion 156 from moving due to the urging of the urging member 140.

The first connecting part 112 and the second connecting part 122 are rotatably coupled to the rotating shaft 128. An elastic member 150 and a pressing member 140 are inserted into the rotating shaft 128.

A friction rubber 132 is provided on the inner side of the other end of the second member 120. The friction rubber 132 is in contact with the friction rubber 116 formed on the inner side of the first member 110 and grips the object.

The pressing member 140 has a disk shape and an outer surface thread 144 is formed on the circumferential surface thereof. A center hole 142 is formed at the center of the pressing member 140.

A rotation shaft 128 is inserted into the center hole 142, thereby enabling the rotation of the pressing member 140.

The outer thread 144 formed around the pressing member 140 is screwed to the inner thread 126 formed on the inner circumferential surface of the second through hole 124 as described above. 3, two portions of the pressing member 140 in contact with the second penetrating portion 124 are engaged with each other, and the two portions of the pressing member 140 in contact with the first penetrating portion 114 The dogs are allowed to rotate freely without screwing. Therefore, when the end portion 111 of the first member 110 and the end portion 121 of the second member 120 are held and pressed, a thread is formed on the inner circumferential surface of the first penetration portion 114 of the first member 110 So that the first member 110 can rotate freely.

The elastic member 150 includes a cylindrical coil portion 152 as a torsion spring and a linear first supporting portion 154 and a second supporting portion 156 protruding outward from the coil portion 152 Respectively. The elastic member 150 is interposed between the first member 110 and the second member 120 and serves to provide an elastic force to the end portions 111 and 121 of the first member 110 and the second member 120 do.

The coil portion 152 of the elastic member 150 is inserted into the rotation shaft 128. The length of the coil part 152 is shorter than that of the rotation shaft 128. [ The first support portion 154 protrudes outward at one end of the coil portion 152 and the second support portion 156 protrudes outward at the other end portion.

The first support portion 154 protrudes upward from the coil portion 152 and comes into contact with the inner surface of the first member 110. The second supporting portion 156 protrudes downward from the coil portion 152 and comes into contact with the inner surface of the second member 120. The first support portion 154 and the second support portion 156 are formed to face in the same direction in the coil portion 152, respectively. The first support portion 154 and the second support portion 156 of the elastic member 150 press the end portions 111 and 121 of the first member 110 and the second member 120 to be spaced from each other, (116, 132).

The first support portion 154 and the second support portion 156 have a shape in which the end portion thereof is bent vertically. The end of the first support portion 154 is inserted into the first fixing hole 118 and the end of the second support portion 156 is inserted into the second fixing hole 134 so that the pressing member 140 is pressed And its movement is restricted.

Both the first support portion 154 and the second support portion 156 are formed to be inclined in the pressing direction (arrow direction in Fig. 4) of the pressing member 140. [ The first supporting portion 154 and the second supporting portion 156 are inclined relative to the pressing direction of the pressing member 140 so that the end portions of the first supporting portion 154 and the second supporting portion 156 This is because the elastic repulsive force against the pressing force of the pressing member 140 can be increased because it is inserted into the first fixing hole 118 and the second fixing hole 134 and its movement is restricted. That is, the first supporting portion 154 and the second supporting portion 156 are inclined with respect to the pressing direction, and the end of the pressing portion 140 is inserted into the first fixing hole 118 and the second fixing hole 134, So that the forceps 100 can not be easily released.

Of course, it is needless to say that the first support portion 154 and the second support portion 156 may be inclined in the direction perpendicular or opposite to the pressing direction of the pressing member 140.

The cross section of the coil part 152, the first support part 154 and the second support part 156 may be circular or polygonal. The coil portion 152, the first support portion 154, and the second support portion 156 may be made of metal, plastic, or the like.

In the tongue 100 according to the present embodiment, the first member 110 and the second member 120 are illustrated as plates having a rectangular shape, but it is needless to say that the first member 110 and the second member 120 may have various shapes.

In addition, in the tongue 100 according to the present embodiment, the inner thread 126 is formed only on the inner circumferential surface of the second penetrating portion 124. The inner circumferential surface of the first penetrating portion 114, Needless to say, threads can be formed.

Hereinafter, the use of the tongue 100 according to the present embodiment will be described.

4 (a), since the coil portion 152 of the elastic member 150 is relatively weakly pressed, the elastic force of the elastic member 150 is not relatively strengthened . At this time, when the user holds the end portion 111 of the first member 110 and the end portion 121 of the second member 120, the friction rubbers 116 and 132 which are in contact with each other are spaced apart from each other, (Not shown). The ends 111 and 121 of the first member 110 are positioned between the first member 110 and the second member 120 so that the ends 111 and 121 of the first member 110 are positioned by the elastic force of the elastic member 150, The end portions 121 of the first member 110 and the second member 120 are spaced apart from each other and the other end portions of the first member 110 and the second member 120 (120) is rotated.

As described above, since the inner thread 126 is not formed on the inner circumferential surface of the first penetration part 114 formed in the first member 110, the first member 110 is pressed against the pressing member 140, It is possible to rotate freely. Since the inner member thread 126 of the second member 120 is threadedly engaged with the outer surface thread 144 formed around the pressing member 140, the frictional force generated at the engagement surface of the second member 120 The first member 110 rotates only relative to the first member 110 and 120 relative to the first member 110.

The elastic force of the elastic member 150 can be adjusted by grasping the object using the first member 110 and the second member 120 and then rotating the pressing member 140. [ When the pressing member 140 exposed to the outside through the first through hole 114 and the second through hole 124 is rotated in one direction, the outer thread 144 formed around the pressing member 140 is rotated in the second direction And moves in the direction of the elastic member 150 along the inner surface thread 126 formed in the penetrating portion 124 to become a state as shown in Fig. 4 (b). Thus, one end of the coil portion 152 is in contact with the pressing member 140 and the other end of the coil portion 152 is in contact with the second connection portion 122.

4 (b), when the pressing member 140 presses the elastic member 150, the first supporting portion 154 and the second supporting portion 156 of the elastic member 150 are in contact with each other, The first support portion 154 and the second support portion 156 are elastically deformed (warped) while being inserted into the first fixing hole 118 and the second fixing hole 134, The elasticity of the two members 120 is increased.

The spring constant is increased when the coil part 152 of the elastic member 150 is pressed by the movement of the pressing member 140 so that the first supporting part 154 and the second supporting part 156 are deformed In order to do this, a larger torsion must be applied. Therefore, the pressing force of the pressing member 140 strengthens the elastic force of the elastic member 150, so that the pressing force corresponding to the force of holding the first and second members 110 and 120 increases.

The pressing member 140 according to the present embodiment has a structure in which the user can rotate the hand to adjust the pressing force. That is, by varying the degree of rotation of the pressing member 140, the strength of the elastic force provided by the elastic member 150 can be adjusted. When the pressing member 140 is positioned at the rightmost position as shown in Fig. 4, the elastic force of the elastic member 150 is set to be the weakest. When the pressing member 140 is positioned at the left side The elastic force of the elastic member 150 is set to be the strongest.

Since the pressing member 140 is partially protruded to the outside through the first penetration portion 114 of the first member 110 and the second penetration portion 124 of the second member 120, The strength of the pressing force of the tongue 100 can be easily adjusted by rotating the pressing member 140. [

Although the pressing member 140 of the tongue 100 according to the first embodiment is illustrated as being coupled to the rotating shaft 128, the present invention is not limited by the position of the pressing member 140. [ The pressing member according to the present invention can be located outside the rotating shaft 128 without being engaged with it. The pressing member 140 may be screwed to a screw thread (not shown) formed on the rotating shaft 124 so as to press one side of the elastic member 150 while being moved by rotation.

The pressing member 140 has a circular plate shape and is pressed against the elastic member 150 by the lateral movement according to the rotation. However, the present invention is not limited by the shape and the movement form of the pressing member 140. Needless to say, the pressing member according to the present invention may have various shapes. For example, the pressing member may have a slant surface, and the slant surface may press the elastic member by rotation of the pressing member.

Although the elastic member 150 is illustrated as having a torsion spring shape, the present invention is not limited by the shape of the elastic member 150. The elastic member according to the present invention may have various shapes such as a leaf spring and the like.

Although the end portions of the first support portion 154 and the second support portion 156 of the elastic member 150 are illustrated as being inserted into the fixing holes 118 and 134, the present invention is not limited to this, It is needless to say that any configuration in which the elastic member 150 does not move in the direction of the arrow. For example, a stopper such as a projection or a groove (not shown) may be formed in place of the fixing holes 118 and 134 so that the elastic member 150 does not move in the pressing direction by pressing the pressing member, .

Second Embodiment

Hereinafter, a tongue 300 according to a second embodiment of the present invention will be described with reference to FIGS. 5 to 6. FIG.

5 is a plan view illustrating a state before the first elastic member 370 and the second elastic member 380 are pressed by the pressing member 350 and FIG. 6 is a plan view illustrating the state before the rotation of the pressing member 350 In which the first elastic member 370 and the second elastic member 380 are pressed. For convenience of explanation in FIGS. 5 to 6, the first member (not shown) that engages with the second member 330 is omitted.

The pressing member 350 for adjusting the elastic force of the first elastic member 370 and the second elastic member 380 is disposed between the first elastic member 370 and the second elastic member 380, And is located outside the rotation shaft 340 into which the rotation shaft 380 is inserted. The pressing member 350 is characterized not to press the coil portions 372 and 382 of the first elastic member 370 and the second elastic member 380 but to support the first supporting portions 376 and 386 do.

5, the minimum pressure point 362 of the pressure member 350 is set so that the first support portion 376 of the first elastic member 370 and the first support portion 386 of the second elastic member 380 Touch. The maximum pressing point 358 of the pressing member 350 is disposed in the longitudinal direction of the first supporting portions 376 and 386 and is not in contact with the first supporting portions 376 and 386.

The distance from the center point 356 of the pressing member 350 to the minimum pressure point 362 is the shortest. Therefore, in the state of FIG. 5, it can be seen that the pressing member 350 does not press or press the first supporting portions 376 and 386 to the minimum.

6, the maximum pressing point 358 of the pressing member 350 is pressed against the first supporting portions 376 and 386, as shown in FIG. 6, when the pressing member 350 is rotated 90 degrees by using the rotary knob 354 in the state of FIG. Respectively. The maximum pressure point 358 is the closest to the first support portions 376 and 386 because the distance from the center point 356 is the greatest. 6, the pressing member 350 presses the first supporting portion 376 of the first elastic member 370 to the left side and the first supporting portion 386 of the second elastic member 380 to the right side .

As described above, the first support portions 376 and 386 are pressed in mutually opposite directions, so that the coil portions 372 and 382 are also pressed in mutually opposite directions. The lengths of the pressed coil parts 372 and 382 are contracted to maximize the elastic force of the second supporting parts 374 and 384 and the first supporting parts 376 and 386.

The pressing force of the clamp 300 can be adjusted by adjusting the elasticity of the first elastic member 370 and the second elastic member 380 by adjusting the degree of rotation of the pressing member 350 in the state of FIG.

The end portions of the first and second support portions 376 and 386 and the second support portions 374 and 384 of the first elastic member 370 and the second elastic member 380 of the tongue 300 according to the present embodiment are fixed However, it is needless to say that the position can be fixed by inserting the end portion into a groove or hole (not shown) formed separately.

Third Embodiment

Hereinafter, the tongue 500 according to the third embodiment of the present invention will be described with reference to FIGS. 7 to 8. FIG.

7 is a view of a tongue 500 capable of adjusting the pressing force according to the third embodiment of the present invention and illustrates a state in which one end of the elastic member 550 is pressed by the rotation of the pressing member 540. FIG. 7, the illustration of the first member that engages with the second member 520 is omitted. And FIG. 8 is a perspective view of the pressing member 540 in the clamp 500 illustrated in FIG.

7 to 8, the tongue 500 capable of adjusting the pressing force according to the present embodiment includes a first member, a second member 520, a pressing member 540, and an elastic member 550 (not shown) .

The second member 520 includes a second connection portion 522 rotatably connected to the first member, a friction rubber 524 provided at the end portion, a rotation shaft 536 into which the elastic member 550 is inserted, 540, which is a rotation center of the pressing member.

The second connecting portions 522 are formed on the left and right sides of the second member 520 so as to protrude upward, and a rotating shaft 536 is coupled therebetween. Spacers 528 are provided at both ends of the rotating shaft 536. The spacers 528 provided on the left and right sides contact the ends of the elastic member 550.

The second connecting portion 522 is provided with a pressing member rotating shaft 532 parallel to the rotating shaft 526. A pressing member 540 is rotatably coupled to the pressing member rotating shaft 532.

The pressing member 540 has an outer wall having a different distance with respect to the rotation center 542 thereof. By the shape of the outside of the pressing member 540, the elastic member 550 can be pressed by the rotation of the pressing member 540. The pressing member 540 is located outside the rotating shaft 526 and the elastic member 550.

7A, the pressing member 540 is not in contact with the elastic member 550, and the pressing member 540 is rotated so that the outer periphery of the pressing member 540 is elastically deformed as shown in FIG. 7 (b) The coil portion 552 of the member 550 can be pressed. The elastic member 550 pressed by the pressing member 540 increases in elastic modulus and requires a larger torsion to deform the first and second supporting portions 554 and 556. [ Therefore, the elastic force of the elastic member 550 can be adjusted by the rotation of the pressing member 540.

The elastic member 550 corresponds to a torsion spring and includes a coil portion 552, a first support portion 554, and a second support portion 556. Since the elastic member 550 of the tongue 500 according to the present embodiment is similar to the elastic member 150 of the tongue 100 according to the above-described embodiment, a detailed description thereof will be omitted. However, the elastic member 550 according to the present embodiment is characterized in that the end portion of the coil portion 552 is not pressed by the pressing member 540, but the side surface thereof is pressed.

9 is an assembled perspective view illustrating a tongue 800 according to a fourth embodiment of the present invention. 9 is a perspective view illustrating a state in which the second member 830 is removed in FIG. 9, FIG. 12 is a perspective view illustrating a state in which the forceps 800 of the first member 810.

9-12, a tongue 800 according to this embodiment includes a first member 810, a second member 830, a pressing member 850, and an elastic member 870.

A pair of elastic members 870 are provided inside the first member 810 and the second member 830 forming the outer body of the forceps 800. [ The elastic member 870 applies an elastic force to the end portions of the first member 810 and the second member 830 so that the first grip portion 818 and the second grip portion 838 can contact each other . The rotation shaft 862 of the pressing member 850 is located inside the coil part 872 of the elastic member 870. The rotating shaft 862 does not press or press the inside of the coil portion 872 while rotating together with the main body 854 of the pressing member 850. [

19) of the elastic member 870 applied to the first member 810 and the second member 830 when the rotating shaft 862 presses the inside of the coil portion 872 of the elastic member 870 The elastic force is increased. As a result, the first member 810 and the second member 830 are brought into stronger mutual contact with each other, thereby increasing the pressing force by which the tongue 800 grasps an object (not shown).

As described above, the tongue 800 according to the present embodiment can adjust the elastic force of the elastic member 870 by adjusting the pressing member 850 (that is, by rotating the pressing member 850) 800 can adjust the pressing force corresponding to the strength of gripping the object.

The first member 810 has a Y-shape and a groove is formed inside the first member 810 so that the pressing member 850 can be positioned. The first member 810 includes a first connection portion 812, a first insertion groove 816, a first grip portion 818, and a first pressing portion 824.

The first grip portion 818 has a shape that is branched into two portions at the end of the first pressing portion 824 and corresponds to a portion gripping the object by the gripper 800. [ The pair of first grip portions 818 come into contact with the second grip portions 838 of the second member 830 due to the elastic force of the elastic member 870. When an external force is applied, the first gripper 818 and the second gripper 838 can be spaced apart from each other to secure a space for gripping the object.

A groove having a semicircular cross section is formed on the inner side of the first grip portion 818, and this groove is also communicated with the groove formed in the first pressing portion 824.

Rubber engagement grooves 822 are formed at the ends of the two first grippers 818. A rubber 890 is coupled to the rubber engagement groove 822, respectively. The rubber 890 is brought into close contact with the object gripped by the gripper 800, so that the holding force can be increased and the object can be prevented from being damaged.

The first pressing portion 824 of the first member 810 extends from the end of the pair of first grippers 818 and corresponds to a portion where the user grasps the gripper 800. The first pressing portion 824 is spaced apart from the second pressing portion 844 of the second member 830 by the elastic force of the elastic member 870. When the external force is applied, the first pressing portion 824 and the second pressing portion 844 may be in contact with each other or may be spaced apart, whereby the first gripping portion 818 and the second gripping portion 838 ) Are spaced apart from each other.

A groove is formed in the first pressing portion 824, and a pressing member 850 and an elastic member 870 are disposed in the groove. Since the grooves formed in the first pressing portion 824 have a certain depth, a space is provided in which the main body 854 of the pressing member 850 can rotate.

A pair of first connection portions 812 are protruded upwardly around the first pressing portion 824. In addition, a pair of first insertion grooves 816 are formed in the first pressing portion 824.

The pair of first connection portions 812 have the same shape, and a first coupling hole 814 is formed at the center of the first connection portion 812 so that the rotation shaft 862 can be inserted. The main body 854 of the pressing member 850 rotates about the rotating shaft 862 and the first member 810 and the second member 830 also rotate. When the first member 810 and the second member 830 are coupled to each other, the second connection portion 832 of the second member 830 is positioned inside the first connection portion 812.

The second support portions 876 of the pair of elastic members 870 are inserted into the pair of first insertion grooves 816, respectively. Since the end of the second support portion 876 of the elastic member 870 is bent, it can be inserted into the first insertion groove 816. The end of the second support portion 876 can be inserted into the first insertion groove 816 by interference fit, thereby suppressing the movement of the elastic member 870, thereby stably providing the elastic force.

The second member 830 is rotatably coupled to the first member 810 to form the outer body of the clamp 800. [ The second member 830 has a shape similar to that of the first member 810 and has a second connecting portion 832, a second fixing hole 836 (see FIG. 18), a second holding portion 838, A portion 844, and a moving portion 846.

The second gripper 838 corresponds to the first gripper 818 of the first member 810 and is formed by a pair of branches. The second gripper 838 comes into contact with the first gripper 818 due to the elastic force of the elastic member 870. At the ends of the pair of second grippers 838, rubber engagement grooves (not shown) are formed, and the rubber engagement grooves are coupled with the rubber 890, respectively.

The second pressing portion 844 extends from the pair of second grip portions 838 and corresponds to the first pressing portion 824 of the first member 810. A groove formed in the inside of the second pressing portion 844 is formed in the inside of the first pressing portion 824 with a groove formed in the inside of the second pressing portion 844 Thereby providing a space in which the pressing member 850 and the elastic member 870 can be located.

A pair of second connecting portions 832 are provided around the second pressing portion 844, and a second fixing hole 836 is provided in the second pressing portion 844. A moving portion 846 is formed outside the second pressing portion 844.

The second connection portion 832 corresponds to the first connection portion 812 of the first member 810 and corresponds to a portion connecting the second member 830 to the first member 810. [ A second coupling hole 834 is formed in the pair of second coupling portions 832. The second engagement hole 834 corresponds to the first engagement hole 814 of the first member 810, and the rotation shaft 862 is inserted.

An arc-shaped seating groove 835 is provided outside the second connection portion 832. When the first member 810 and the second member 830 are coupled to each other in the seating groove 835 as shown in FIG. 9, the end of the first connection portion 812 is positioned.

The pair of second fixing holes 836 are formed on the inner side of the second pressing portion 844 and corresponds to a portion where the end of the first supporting portion 874 of the elastic member 870 is inserted. The end of the first supporting portion 874 of the elastic member 870 is inserted into the second fixing hole 836 and the end of the second supporting portion 876 is inserted into the first insertion groove 816. [ As a result, the elastic member 870 can stably provide the elastic force without moving inside the first member 810 and the second member 830.

The moving part 846 is formed with a predetermined length outside the second member 830 and provides a passage through which the handle 852 of the pressing member 850 can move and can be projected to the outside.

The first member 810 and the second member 830 forming the outer body of the tongue 800 according to the present embodiment have been illustrated as Y-shaped similarly to each other. However, the present invention is not limited to the shapes of the first member 810 and the second member 830, and the shape thereof may be variously changed. In addition, a bar-shaped elastic member (not shown) may be provided at the ends of the first member 810 and the second member 830. The elastic member is deformed corresponding to the shape of the object gripped by the gripper 800, thereby making it possible to hold the object more strongly.

Hereinafter, the pressing member 850 for adjusting the pressing force of the forceps 800 will be described with reference to FIGS. 13 to 17. FIG.

Fig. 13 is an assembled perspective view of the urging member 850, Fig. 14 is a front view of Fig. 13, and Fig. 15 is an exploded perspective view of the urging member 850 illustrated in Fig. 16 is a front view of the main body 854 of the pressing member 850, and Fig. 17 is a front view of the rotating shaft 862. Fig.

13 to 17, the pressing member 850 is located inside the first member 810 and the second member 830 and presses the elastic member 870 inside the pressing member 850, To control the elasticity of the spring. The pressing member 850 includes a main body 854 and a rotating shaft 862.

The main body 854 corresponds to a regulating means for determining whether the rotating shaft 862 presses the elastic member 870 and the degree of pressing, and rotates integrally with the rotating shaft 862. 9 and 14 illustrate a state in which the rotation shaft 862 does not press the elastic member 870 due to the rotation of the main body 854. 9 and 14, when the main body 854 rotates in the counterclockwise direction, the rotation shaft 862 also rotates together to press the elastic member 870.

As described above, since the both end portions of the elastic member 870 are inserted into the first insertion hole 816 and the second fixing hole 836, they are elastically deformed without being moved by the pressure of the rotation shaft 862 Thereby providing an enhanced elastic force to the first member 810 and the second member 830.

The body 854 of the pressing member 850 has a disk shape and a body frame 858 and a handle 852 are formed around the body 854 and a through hole 856 is formed at the center thereof.

The rotation shaft 862 is inserted into the through hole 856 formed at the center of the main body 854. A locking projection 857 is formed inside the through hole 856. The locking projection 857 is inserted into the locking groove 864 formed around the rotation shaft 862. [ Due to the engagement structure of the rotation shaft 862 and the main body 854, the rotation shaft 862 rotates integrally with the main body 854.

The main body frame 858 is formed symmetrically in an arcuate shape around the main body 854. 13, the main body frame 858 is not formed in the portion where the second support portion 876 of the elastic member 570 is located but is formed in the portion where the first support portion 874 is located . The first support portion 874 can be in contact with the main body frame 858 and the second support portion 876 can be in direct contact with the main body 864 according to the length of the coil portion 872 of the elastic member 870 .

The first support portion 874 and the second support portion 876 of the elastic member 870 are disposed laterally (that is, on the rotation shaft 862) by the contact structure of the first support portion 874 and the second support portion 876, In the direction perpendicular to the longitudinal direction of the rotation shaft 862 without being deformed in the longitudinal direction of the rotary shaft 862. [ It is possible to provide a more elastic force to the first member 810 and the second member 830 when the first support portion 874 and the second support portion 876 are vertically deformed as compared with the case where the first support portion 874 and the second support portion 876 are deformed laterally have.

The handle 852 is protruded from the outside of the main body frame 858 and is exposed to the outside of the second member 830 through the moving portion 846 as illustrated in Fig. The user can adjust the elastic force of the elastic member 870 by rotating the main body 854 and the rotation shaft 862 of the pressing member 850 using the handle 852. [

The rotation axis 862 corresponds to the center of rotation of the first member 810 and the second member 830 and the urging member 850. The rotating shaft 862 rotates integrally with the main body 854 of the pressing member 850 and presses the inside of the coil portion 872 of the elastic member 870 according to the rotational angle. 13 shows a state in which the rotating shaft 862 does not pressurize the elastic member 870 or presses the elastic member 870 relatively weakly since the pressing surface 868 of the rotating shaft 862 is in contact with the inside of the coil portion 872 .

The rotation shaft 862 is inserted into the through hole 856 of the main body 854 and is exposed to the outside because the length thereof is larger than the thickness of the main body 854. A coil portion 872 of a pair of elastic members 870 is inserted into a portion exposed from the rotation shaft 862 to the left and right of the main body 854.

The rotation shaft 862 has an engagement groove 864 formed on its outer side surface in the longitudinal direction. A locking protrusion 857 of the through hole 856 is inserted into the locking groove 864 so that the main body 854 and the rotation shaft 862 rotate integrally.

The rotation axis 862 may have a different distance from the rotation center c to the circumferential surface. For example, the distance from the rotation center c to the pressing surface 866 may be formed to be longer than the distance to the pressing surface 868. When the pressing surface 866 contacts the inside of the coil portion 872 as compared with the case where the non-pressing surface 868 contacts the inside of the coil portion 872 by the rotation of the rotation shaft 862, The elastic deformation is further increased and the pressing force of the clamp 800 is further increased.

14 and 18 illustrate a state in which the ratio of the rotating shaft 862 to the pressing surface 868 is in contact with the coil portion 872 of the elastic member 870 by the rotation of the pressing member 850. [ At this time, the non-pressurized surface 868 may be positioned to be in contact with or spaced apart from the coil portion 872.

14 and 18, when the pressing member 850 is rotated to rotate the rotating shaft 862, the pressing surface 866 presses the inside of the coil portion 872, whereby the elastic member 870 The elastic force applied to the first member 810 and the second member 830 increases, so that the pressing force by which the gripper 800 grasps an object increases.

The elastic member 870 provides an elastic force within the first member 810 and the second member 830 so that the tongue 800 has a pressing force. The elastic member 870 is disposed on both right and left sides of the body 854 of the pressing member 850 and has a cylindrical coil portion 872 and a first supporting portion 874 and a second supporting portion 872, (876).

The rotating shaft 862 is located inside the coil portion 872. The rotating shaft 862 may not press or press the inside of the coil portion 872 by rotation, so that the pressing force of the gripper 800 can be adjusted.

Although the coil portion 872 is illustrated as being formed in a circular shape, the present invention is not limited by the shape of the coil portion 872. [ It is needless to say that the coil portion may have various shapes such as an elliptical shape or a polygonal shape, and the sectional shape of the rotation shaft may be changed corresponding thereto.

In the coil portion 872, the first support portion 874 and the second support portion 876 extend in mutually different linear directions. The first support portion 874 is inserted into the second fixing hole 836 formed inside the second pressing portion 844 of the second member 830 and the second supporting portion 876 is inserted into the first member 810, Is inserted into the first insertion groove (816) formed inside the first pressing portion (824). As a result, the elastic member 870 can be fixed in position within the first member 810 and the second member 830. [

The first support portion 874 contacts the main body edge 858 of the main body 854 and the second support portion 876 contacts the side surface of the main body 854 directly. Therefore, the elastic member 870 can not move in the longitudinal direction of the rotation shaft 862, but can move in the direction perpendicular to the longitudinal direction of the rotation shaft 862. [ This allows the elastic member 870 to effectively press the first pressing portion 824 of the first member 810 and the second pressing portion 844 of the second member 830 to increase the pressing force.

Hereinafter, a method of adjusting the pressing force of the tongue 800 according to the present embodiment will be described with reference to FIGS. 18 to 20. FIG.

18 is a view illustrating a state in which the elastic force of the elastic member 870 is relaxed to the maximum by the rotation of the pressing member 850. [ 19 is a view illustrating a state in which the urging member 850 is rotated to thereby maximize the elastic force of the elastic member 870 in FIG. 18, and FIG. 20 is a front view of the urging member 850 in FIG.

18, when the handle 852 of the pressing member 850 is positioned at the right end of the moving part 846, the uneven surface 868 of the rotating shaft 862 is pressed against the coil part 870 of the elastic member 870 872, but spaced apart by a certain distance. Therefore, since the rotary shaft 862 does not press the coil portion 872 of the elastic member 870, the forceps 800 have a relatively weak pressing force.

In the state of Fig. 18, when the pressing member 850 is turned counterclockwise by using the knob 852, the state shown in Figs. 19 and 20 is obtained. The rotating shaft 862 rotates together with the rotation of the pressing member 850 so that the pressing surface 866 of the rotating shaft 862 presses the inside of the coil portion 872. [ The coil portion 872 of the elastic member 870 moves slightly in the lateral direction (right direction in FIG. 19) and the first support portion 874 and the second support portion 876 move by the pressing by the pressing surface 866, Is maintained in a slightly bent state. As described above, the elastic member 870 elastically deformed by the pressure of the pressing surface 866 applies a greater elastic force to the first member 810 and the second member 830, so that the pressing force of the tongue 800 is increased .

19 illustrates a state in which the pressing force of the gripper 800 is maximized. However, it is needless to say that the pressing force of the gripper 800 can be adjusted by varying the degree of rotation of the pressing member 850. FIG.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.

21 is a view illustrating an elastic member 970 according to another embodiment of the present invention.

21, the elastic member 970 includes a coil portion 972, a first support portion 974, and a second support portion 976 as coil springs. A cushioning portion 975 is provided at the center of the first support portion 974. When the elastic member 970 is pressed by the pressing member, the first support portion 974 and the second support portion 976 are fixed and elastically deformed by the stopper. At this time, the buffer portion 975 is elastically deformed The elastic force is further increased and the first support portion 974 is prevented from being deformed.

Although the buffering part 975 is illustrated as being provided only in the first supporting part 974, it may be provided in the second supporting part 976 as well. Further, although the buffer portion 975 is illustrated as having a circular coil shape, it goes without saying that it may have various shapes.
