Description

  The present invention relates to a manual tool, and more particularly to a monkey wrench that combines a traditional drive method and a unidirectional drive method.

  Generally, when a polygonal bolt or nut is tightened or loosened with a movable wrench, it is necessary to repeatedly move and fit the movable wrench. However, such an operation method is not only very troublesome but also troublesome for the user. Therefore, in order to solve this problem, various improved movable wrenches are emerging one after another in the market. Such a movable wrench can be easily tightened with a polygonal bolt or nut by reciprocatingly rotating the handle of the wrench like a ratchet wrench.

  The “movable wrench having an improved structure” disclosed by Patent Document 1 is a prior art of a movable wrench registered by the present inventor and includes a fixed jaw, a movable jaw, a handle, a shaft, and a stopper. When reciprocating the handle, the handle can reciprocate the stopper in the fixed jaw by the fulcrum formed at the connection point between the front end of the handle and the fixed jaw, and the locking effect of the movable jaw can be released. The movable jaw can be continuously released from the fixed jaw or restored to the fixed state by the elastic action of the spring mounted on the shaft in the slot of the fixed jaw. It is possible to achieve the effect of tightening polygonal bolts or nuts once or continuously.

However, the wrench described above still does not achieve the dual effect of combining the traditional drive method and the unidirectional drive method, but only provides a single effect of tightening bolts or nuts in a single direction like a ratchet wrench. There is room for improvement.

Hereinafter, an adjustable wrench according to the present invention will be described with reference to the drawings.
(First embodiment)
As shown in FIGS. 1 to 4, the monkey wrench according to the first embodiment of the present invention includes a fixed jaw 1, a movable jaw 2, an operation unit 3, a handle 4, a stopper 5, and a fixed unit 6.
The fixed jaw 1 has a mounting chamber 11. The mounting chamber 11 has a runway 12 communicating with the mounting chamber 11 at the upper side, a connecting groove 13 communicating with the outside at the lower side, and a lateral perforation 14 on one side. The perforation 14 has a radial through hole 15, and the through hole 15 communicates with the connection groove 13.

  The movable jaw 2 is mounted in the runway 12 of the fixed jaw 1 and moves in the lateral direction along the runway 12 so that the distance between the movable jaw 2 and the fixed jaw 1 can be adjusted. 21 can be formed. The movable jaw 2 has a tooth portion 22 at the bottom.

  The operating unit 3 is mounted on the mounting chamber 11 of the fixed jaw 1 and has a shaft 31 and a spring 32. The shaft 31 includes a first end 311, a second end 312, a middle step 313 positioned between the first end 311 and the second end 312, a middle step 313, and a second end 312. And a blocking portion 314 formed by reducing the diameter between them. The second end 312 and the blocking part 314 are mounted in the perforation 14 of the fixed jaw 1, and the blocking part 314 corresponds to the through hole 15. The middle portion 313 has a spiral roller 33 on the outer periphery, and the roller 33 meshes with the tooth portion 22 at the bottom of the movable jaw 2, so that the movable jaw 2 moves laterally and is fixed as the roller 33 rotates. It is possible to adjust the interval between the sections 21. The spring 32 is fitted into the middle step 313 of the shaft 31, and both ends of the spring 32 abut against the roller 33 and the inner wall of the mounting chamber 11 separately.

  Since the handle 4 has the shaft hole 41 at the front end and is connected to the connection groove 13 at the bottom of the fixed jaw 1 by the connecting shaft 42, the handle 4 can be expanded or retracted by moving the arc. . The handle 4 has a recessed groove 43 that is used for mounting the elastic body 44 on one side facing the connecting shaft 42 on the front end. One end of the elastic body 44 abuts against the inner edge of the connection groove 13. In the present embodiment, the elastic body 44 is a spring. The handle 4 has a locking and fixing portion 45 having a predetermined shape on the side of the recessed groove 43. The handle 4 has a hook 46 on the other side facing the connecting shaft 42 on the front end.

  The stopper 5 is mounted so as to slide in the through-hole 15 of the fixed jaw 1, and one end is connected to the hook 46 at the front end of the handle 4, so that when the front end of the handle 4 and the fixed jaw 1 are rotated, The front end of 4 can interlock and slide the stopper 5, and the other end of the stopper 5 can selectively block the blocking portion 314 of the shaft 3.

  The fixed unit 6 has a trapezoidal shape and is attached to one side of the connection groove 13 of the fixed jaw 1. The fixing unit 6 has a position restriction portion 64 corresponding to the shape of the locking and fixing portion 45 of the handle 4 on both adjacent planes facing the locking and fixing portion 45. The fixing unit 6 has a fixing hole 67 on the end surface. The fixed jaw 1 has a slide groove 16 facing the fixed hole 67 on the outside of the bottom. Since the pin 63 is mounted in the fixing hole 67 of the fixing unit 6 from the slide groove 16 outside the connection groove 13 and has a lever 631 at one end toward the outside of the fixing jaw 1, if the lever 631 of the pin 63 is moved, The fixing unit 6 is interlocked by a pin 63 and can be coupled and separated along the slide groove 16 with respect to the locking / fixing portion 45 of the handle 4.

  When the fixing unit 6 is coupled to the locking / fixing portion 45 of the handle 4 by the position limiting portion 64, the handle 4 exhibits a non-rotatable state due to the limit locking of the position limiting portion 64. Further, by adjusting the position of the fixing unit 6 and separating the position restricting portion 64 and the locking and fixing portion 45 of the handle 4, the position between the locking and fixing portion 45 of the handle 4 and the position limiting portion and 64 of the fixing unit 6 is increased. In addition, a rotation space 7 is formed when the handle 4 is rotated with respect to the fixed jaw 1.

  As shown in FIG. 3, when tightening the polygonal bolt 8, the roller 33 is moved to sandwich the polygonal bolt 8, and the interval between the fixed sections 21 is adjusted. At this time, the stopper 5 at the front end of the handle 4 and the blocking portion 314 of the shaft 31 in the fixed jaw 1 mesh with each other, so that the fixed section 21 can maintain a fixed interval. When the lever 631 of the pin 63 is moved so that the position limiting portion 64 of the fixing unit 6 and the locking fixing portion 45 of the handle 4 are engaged with each other, the shape of the locking fixing portion 45 and the shape of the position limiting portion 64 correspond to each other. Therefore, when the handle 4 is moved, the front end of the handle 4 is locked by the position restricting portion 64 of the fixed unit 6, and the handle 4 does not rotate with respect to the fixed jaw 1. Therefore, the monkey wrench according to the present embodiment can have a conventional method of operating a movable wrench.

  As shown in FIG. 4, when the lever 631 of the pin 63 is moved to separate the position restricting portion 64 of the fixing unit 6 from the locking fixing portion 45 of the handle 4, the locking fixing portion 45 of the handle 4 and the fixing unit 6 are separated. A rotation space 7 for rotating the handle 4 with respect to the fixed jaw 1 is formed between the position restricting portion 64 and the fixed jaw 1. As shown in FIG. 5, when the handle 4 is moved counterclockwise with the connecting shaft 42 at the front end of the handle 4 as a fulcrum, the handle 4 rotates toward the turning space 7, and the elastic body 44 at the front end of the handle 4. Hits the inner edge of the connection groove 13 and exhibits a compressed state. At this time, the stopper 5 is interlocked with the handle 4, moves away from the position of the blocking portion 314 of the shaft 31, and releases the blocking of the shaft 31. Therefore, when the front end of the movable jaw 2 is pressed by the obtuse angle of the polygonal bolt 8, the movable jaw 2 is moved outward together with the roller 33, and the spring 32 in the mounting chamber 11 is compressed by the compression of the roller 33, Since the fixed section 21 is slightly opened, it is easy to rotate the handle 4 counterclockwise.

  When the handle 4 is rotated clockwise and restored to the state shown in FIG. 4, the compressed elastic body 44 is restored by the elastic action, and the front end of the handle 4 slides the stopper 5 to the blocking portion 314 of the shaft 31. Presents a locked state. The compressed spring 32 pushes the roller 33 pressed outward by the elastic restoring action back to the original position, and the fixed section 21 restores the original interval, so that the polygonal bolt 8 is continuously rotated. Is possible. In addition, by repeating the tightening operation once or continuously, it is possible to omit operations such as separation and fitting, and to easily complete the operation of tightening the polygonal bolts.

Since 62 abuts between the inner wall of the connection groove 13 and the depressed portion 61, the fixing unit 6 </ b> A is connected in the connection groove 13 and faces the locking fixing portion 45 of the handle 4. The fixed unit 6A has a position limiting portion 64A corresponding to the shape of the locking and fixing portion 45 of the handle 4 on the outer periphery, a movable portion 65 that is retracted to the inside, and a lever 66 that protrudes to the outside. If the fixing unit 6A is rotated, the fixing unit 6A can be selected to face the locking / fixing portion 45 of the handle 4 by the position limiting portion 64A or to face the locking / fixing portion 45 of the handle 4 by the movable portion 65. is there. In the present embodiment, the locking and fixing portion 45 of the handle 4 exhibits a depressed arc surface, and the position restricting portion 64A exhibits a protruding arc surface, and therefore the positions of the locking and fixing portion 45 of the handle 4 and the fixing unit 6A. If the restricting portion 64A is engaged with each other, the locking effect is fully provided by connecting the two arc surfaces, and it is possible to reliably resist the torque generated when the handle 4 is rotated by an external force. is there.

  When the fixed unit 6A faces the locking / fixing portion 45 of the handle 4 by the position limiting portion 64A, the position limiting portion 64A of the fixing unit 6A and the locking / fixing portion 45 of the handle 4 are engaged with each other, and the handle 4 is positioned to the position limiting portion 64A. The non-rotating state is exhibited due to the restriction locking. When the position of the fixed unit 6A is adjusted, the position restricting portion 64A and the locking and fixing portion 45 of the handle 4 are separated, and the movable portion 65 and the locking and fixing portion 45 of the handle 4 face each other, the engagement of the handle 4 A rotation space 7A for rotating the handle 4 with respect to the fixed jaw 1 is formed between the fixing portion 45 and the movable portion 65 of the fixed unit 6A.

  As shown in FIG. 9, when the lever 66 of the fixing unit 6A is moved and the position restricting portion 64A of the fixing unit 6A and the locking fixing portion 45 of the handle 4 are engaged with each other, the front end of the handle 4 is positioned at the position of the fixing unit 6A. The handle 4 is locked by the restriction portion 64A, and the handle 4 cannot rotate with respect to the fixed jaw 1. Therefore, the monkey wrench according to the present embodiment can have a conventional method of operating a movable wrench.

  As shown in FIG. 10, the lever 66 of the fixed unit 6A is moved so that the movable portion 65 of the fixed unit 6A and the locking / fixing portion 45 of the handle 4 face each other. When 45 is separated, a turning space 7A for turning the handle 4 with respect to the fixed jaw 1 is formed between the locking and fixing portion 45 of the handle 4 and the movable portion 65 of the fixing unit 6A. Therefore, as shown in FIG. 11, when the handle 4 is moved counterclockwise with the connecting shaft 42 at the front end of the handle 4 as a fulcrum, the handle 4 can be turned toward the turning space 7A. Similarly, the monkey wrench can achieve the effect of tightening polygonal bolts once or continuously.
