New description: [New technical field] This creation involves the inflammatory technology in the field of tools, which combines two separate objects into one and can be removed.曰 【Prior Art】 The construction site combines the tools and the operating parts into a body that can be removed, which is nothing more than a screw lock. However, the assembly or = = time is quite long, so the development and the clamping mechanism are installed and removed. 〗 There are quite a few gripping mechanisms known to women, and the Taiwanese (4) new patent case is taken as an example. The structure is as follows: \ The clamping mechanism of the figure is 1〇t, which is the front section of a front cover and a body 12. The outer periphery utilizes a first compression spring 13 between the front cover π gold rod body f2 to bring the front cover u toward the rod body. The tail is normal. The inside of the rod body 12 has a class of bores, and the second (four) springs 15 and cylinders 16 are accommodated in the lower section, and the cylinder 16 is supported by the wall surface of the class hole 14 by the Ϊ = 15; The spring forces of the two springs 13, 15 cancel each other out, so that 16 is hidden in the larger aperture section of the class hole 14 (4) = = open - right ... 'each notch 17 accommodates one: round ^ the rod body moves in response to the 1U 16 retracted hole 14 The inner tapered surface 19 that contacts the open end of the larger aperture section. Formed when an operating member A is intended to enter the shaft 12 through the front cover u, the second member must be displaced in the direction of the arrow, and the cylinder 16 is ejected outward by the elastic force of the first: pressure: the bee 15 until the end of the barrel abuts against the front u. At this moment, the round bar 18 can be pushed away by the operating member A, causing the two: 乍: A-contact A to be moved from the original small-diameter end to the large-diameter end, and the air, the opening A is detached. However, the distance that the flip cover 11 moves outward along the arrow is not limited, and the length of the inner taper surface 19 from the small diameter end to the large diameter end is dropped by the restraint of the inner fin 19 and the front cover 1 is obstructed. The phase cup cup rainbow 12 enters the homing movement, no longer produces a clamping effect. Solution: How to make the clamping effect effective? It becomes a new object of this creation [new content] "In view of this, the creator has in-depth discussion of the problems of prior art, and actively seeks solutions through years of experience in R&D and manufacturing of related industries. Tao, finally succeeded in developing a clamping mechanism to improve the problem of custom creation. The main purpose of this creation is to use a continuous coil to enhance the clamping effect and is not easily blocked. Due to the above objectives, this creation provides a clip. The holding mechanism comprises: a dry body comprising a receiving portion and a bead hole, the bead hole having a large opening through the outer surface of the rod and a small opening π passing through the inner wall of the receiving portion; the bead body entering the bead hole can be partially a small opening is exposed; a front cover is coupled to the rod body and forms a receiving space; and a limiting member is disposed in the receiving space between the front cover and the rod body, the limiting member includes a plurality of continuous coils surrounding the rod body The outer surface of the M438949 is covered with a large opening. The rod body here refers to a connecting rod, a rod suitable for the universal joint head or a fixed joint. A member such as a rod of a wire driver. The housing portion referred to herein is a receiving groove that is caught at the end of the rod body, or a through hole that passes through both ends of the rod body. Further, the clamping force of the connecting device on the operating member, Appropriate adjustment effect can be obtained by replacing metal strips of different thickness or beads of different sizes. Therefore, an operation member is inserted into the accommodating portion, forcing the beads to retreat into the bead holes and partially exposing the large opening, touching the beads The coil is expanded in diameter, and the diameter of the remaining coils is relatively reduced. The diameter-reduced coil will tighten the outer surface of the rod, and at the same time accumulate the elastic force, increase the coil expansion force of the diameter expansion, strengthen the pressing force, and obtain the effect of the homing of the beads. The clamping mechanism further comprises a locking structure. The locking structure is mounted on the rod body and is reciprocally displaceable, and is located at the periphery of the coil and the diameter of the restriction is not to be expanded, and the locking function is released when leaving the coil. Hereinafter, the purpose of the related embodiment is described based on the detailed description of the drawings. Structure and characteristics, I believe that the techniques, means and functions used in this creation can be obtained from an in-depth and specific understanding. Referring to Figures 2 to 4, it is shown that a clamping mechanism 20 is composed of a rod body 21, a bead body 30, a front cover 31 and a restraining member 40. The end portion of the rod body 21 forms a class segment 22 The small diameter portion passes through the hollow portion of the front cover 31, and the large diameter portion is locked with the inner wall of the front cover 31 to form a accommodating and accommodating member 40 between the front cover 31 and the rod body 21. The space 23 is inserted into the accommodating portion 24 from the small diameter portion of the segment 22 to the other end of the rod body 21. The accommodating portion 24 of the embodiment is a receiving groove which is divided into a hexagonal hole segment and a volume adjacent to the end of the rod body 21. a smaller circular groove section, and a bead hole 25 is formed in the hexagonal hole segment wall surface and the small diameter portion of the segment 22. The bead hole 25 has a large opening 26 and a small opening 27, and the large opening 26 passes through the small diameter portion. Appearance and straight through the accommodating space 23, the small opening 27 communicates with the accommodating portion 24 through the wall surface of the hexagonal hole segment. The bead body 30 enters the bead hole 25 via the large opening 26, limited by the restriction member 40 not departing. The bead body 30 has a diameter larger than the depth of the bead hole 25, and partially exposes the small opening 27 without falling, so that the bead body 30 partially protrudes from the wall surface of the hexagonal hole portion of the receiving portion 24. The restricting member 40 is a metal strip wound in a spiral direction into a plurality of continuous coils 41. These coils 41 surround the small diameter portion of the segment 22 while being restrained by the front cover 31 to cover the large opening 26 of the bead hole 25. When the tail section of the operating member A is inserted into the accommodating portion 24 by the arrow, the wall portion of the circular groove segment is not allowed to continue deep because the tail segment body is the same as the hexagonal hole segment. At this moment, the operating member A applies a force to the bead body 30, forcing the bead body 30 to retreat into the bead hole 25 while partially exposing the large opening 26, thereby expanding the diameter of the coil 41. The coil 41 that touches the bead body 30 will tighten the outer portion of the small-diameter portion of the segment 22, and the operating member A cannot be easily separated from the pressing bead body 30. According to the above configuration, the derivatized embodiment is as follows: • Fig. 5 depicts a precision screwdriver which differs from the previous embodiment in that the segment 46 is defined as the end of the rod: 45 based on the clamping mechanism 44. A support portion 47 extends at the end of the rod body 45, and the support portion 47 is slightly formed into a m-shaped portion 48, and is integrated with the end sleeve 49. = The stage section 46 of the precision screwdriver, which can be socketed, is clamped by the clamping mechanism 44 and can be removed and replaced. ^ Figure 6 draws a separate clamping mechanism 5 〇, with the second release of the connecting rod, and a slight change on the original basis, with a sliding sill 54 to create a locking function. Therefore, the difference between the present clamping mechanism 50 and the above-described embodiment is as follows: 1) The sleeve 90 is placed on the periphery of the flat rod 51 and smoothly moves back and forth along the length of the rod. The sleeve 54 has a small barrel portion = and a large barrel portion 58. The small tubular portion 57 is inserted into the semi-closed space of the rod body 51 and the front cover, and has a function of not expanding the diameter of the coil 56. The large tubular portion 58 and the rod body 51 are framed by another semi-closed empty door valley, a compression spring 35 and a gasket 36. The gasket 36 is blocked from the outer surface of the body 51 and must not leave, supporting the compression bomb: 35 The inner wall of the large cylinder is restrained, and the sliding sleeve 54 is pushed forward to the normal state. 2) Since a groove 53 accommodates the coil %, the surface of the rod body 51 is not obstructed by the small cylindrical portion 57 which reciprocates. The groove 53 is surrounded by the rod body 51 in the circumferential direction, and the bottom surface of the groove is divided into two by the two bead holes 55. At the same time, the groove 53 has a high and a poor gap from the groove to the bottom of the groove. Do not leave, only surround the outside of the bottom of the slot and cover the large opening. 3) The end of the front cover 52 is regarded as the front end of the rod body 5, and an insertion portion 59 is axially extended at the end of the _51. The insertion section 59 has a groove which is detachably integrated with a tool B, and the holding mechanism 50 is coupled to the required operation member A as shown in Fig. 7. Next, as seen in Fig. 8, the sliding force of the sliding sleeve 54 of the clamping mechanism 50 is applied, and the arrow is displaced in the direction of the insertion end 59 by the dotted arrow, so that the small cylindrical portion 57 is separated from the periphery of the coil 56. At the same time, the compression spring 35 is pressed by the inner wall of the large tubular portion 58 and the spacer 36 to accumulate the elastic force required for returning. At this point, the coil 56 surrounding the recess 53 is free. Therefore, the tail portion of the operating member A is inserted into the opening of the rod body 51 according to the solid arrow, forcing the bead body 30 to retreat into the bead hole 55, and at the same time partially exposing the large opening, and the coil 56 contacting the bead body 30 is expanded in diameter to block the return of the sliding sleeve 54. Bit. The diameter of the coil 56, which is not touched by the bead body 30, is relatively reduced, and the bottom surface of the tightening groove 53 causes the elastic force of the pressed bead body 30. In Fig. 9, the groove of the operating member A faces the bead hole 55, so that the bead body 30 loses the support of the operating member A and no longer contends with the coil 56. The coil 56 is restored to its original shape by the elastic force, forcing the bead body 30 to be hidden from the large opening of the bead hole 55, and at the same time partially exposing the small opening to cause a jamming effect on the groove of the operating member A. The external force applied to the sliding sleeve 54 is released, and the large tubular portion 58 is urged by the elastic force of the compression spring 35 to slide the sliding sleeve 54 along the dotted arrow on the periphery of the flat surface 51 until the small tubular portion 57 is blocked. At this moment, the small cylinder portion 57 returns to the periphery of the coil 56, and the diameter of the coil 56 is not allowed to expand, resulting in a latching effect. Of course, the latching action can be released by itself after the sliding sleeve 54 is removed, so that the operating member A can be pulled away from the clamping mechanism 50. 0 Figure 10 is also a separate clamping mechanism 60 with a more excellent locking structure for easier and easier use. Of course, the overall configuration and the foregoing embodiment may be slightly changed, for example: a) The sliding sleeve 54 is constructed to approximate the upper opening embodiment, but the assembly orientation is reversed, and the small cylindrical portion 57 is inserted into the compression spring 35 to provide a sleeve. 54 required elasticity. The inner wall of the large cylindrical portion of the sliding sleeve 54 is blocked by the j-bead 65, so that the open end of the large tubular portion 58 partially enters the semi-closed space surrounded by the rod body 61 and the front cover 52 as a normal state. "b) The difference between the sliding sleeve 54 and the foregoing embodiment is that the basin is in the outer sleeve 7G (four)' and is shaped in the large cylindrical portion - the driven portion 66. The driven portion 66 is referred to herein as the difference in the large cylindrical portion. The annular plane c. The aforementioned bead body 65 is placed in a bead hole 64, and the bead is at the depth of the bead hole 64. The bead hole 64 is disposed on a small diameter portion of the rod body 61 and has an opening having an equal aperture, allowing Bead body 65 standing = one opening, contact - deep rod y 58 深入 deep into the accommodating portion 24!

The Χ 5 together with the reset magazine 76 is placed inside the M438949 accommodating portion 24 of the rod 61. The short rod 75 is formed with a first step 77 and a second step 78. The first step 77 is lower in height than the short rod 75, but higher than the second step 78, and the supporting bead 65 stays in the bead hole 64, but does not The accommodating portion 24 of the body 61 is detached from the rod. The reset magazine 76 abuts against the closed end of the short bar 75 and the receiving portion 24, and generates an elastic force for the opening of the short bar 75 toward the opening portion 24. In Fig. 11, the tail portion of the operating member A is inserted into the accommodating portion 24 of the rod body 61, pushes the short rod 75 back into the depth of the accommodating portion 24, and presses the return spring 76. At the same time, the bead 65 falls from the first step 77 into the second step 78, and φ no longer contacts the inner wall of the large barrel 58. At this moment, the sliding sleeve 54 receives the elastic force of the compression spring 35, and penetrates into the semi-enclosed space surrounded by the rod body 61 and the front cover 52, and the diameter of the limiting coil 56 is not expanded to achieve the purpose of locking. Therefore, the two beads 30 sandwich the groove, preventing the operating member A from leaving the clamping mechanism 60. As shown in Fig. 12, the outer casing 70 is displaced in the direction of the broken arrow, and the driven portion 66 of the large tubular portion 58 is resisted, and the sliding sleeve 54 is moved in the same direction to press the compression spring 35, and the locking effect is released, so that the large tubular portion is released. The coil 56 is no longer limited. At this point, the small barrel portion 57 no longer seals the opening of the bead hole 64. When the elastic force of the short rod 75 is greater than the pressing force of the coil 56, the operating member A can be pushed to the opening of the receiving portion 24 by the solid arrow, so that the bead body 30 comes from the groove to the outer surface of the operating member A, so that the diameter of the coil 56 contacting the bead body 30 is made. expansion. At the same time, the short rod 75 drives the bead body 65 from the second step 78 to the first step 77, again resisting the inclined inner wall of the large tubular portion 58, and blocks the sliding sleeve 54 from penetrating into the front cover 52. - It is worth noting that the short rod 75 spring force will be offset by the clamping force of the bead body 30, so the operating member A is not easy to be detached from the rod body 61, and it is easy to draw 10 M438949 ί ° at any time and then loosen the outer sleeve 7G to make it elastically contact. The cover 52 returns to the state of Fig. 11. A part of the clamping mechanism 80 is formed on the basis of the foregoing embodiment. L) The small-diameter portion 82m of the rod body 81 has a non-circular cross section, and the grip 83 encloses a portion of the small-diameter portion 82. The reed t-slot wall resists the contractile force. The moon sleeve 54 and the tendon 85 provide the desired bomb 58 round = the front cover 85 is active. The inner wall of the front cover 85 contacts the large tubular portion. The peripheral support is sleeved at the large diameter portion of the rod 81 with a small diameter end. The outer support 85 reciprocates at the rod body 81. The front cover 48) 5 is located near the end of the diameter portion 86, restricting the restraint of the bead (4) and bounces toward the == force. The large cylinder portion is missing the front cover 85. At the moment, until the slave part is in conflict with the dream floating person a ^ limit coil 56 straight set
