Abstract
Description
Technical Field
[0001] The present invention relates to a torsion structure, and more particularly to a torsion structure in which, under the elastic action of a first washer, the second body and the locking member are pushed apart from each other, causing the fixing member to abut against the first surface and the second surface, thereby eliminating the gap between the second body and the locking member. This allows the torsion structure to have the dual advantages of easy assembly and gap elimination, thus achieving the best of both worlds. Background Art
[0002] As previously known, common torsion structures, such as US Patent No.: US6463834B2
[0003] However, the disadvantages of this common torsion structure are:
[0004] 1. The plurality of fixing members 75 are arranged on the fixing portion 34 and the fixing seat 74. The fixing members 75 commonly used in the industry are in the shape of a tip or a bead. If the fixing members 75 are Figure 2 The fixing member 75 needs to be assembled at the fixing portion 34 and the fixing seat 74 by external force, that is, the three are tightly fitted, and there is no relative tolerance between the second body 30 and the fixing seat 74. The rotation adjustment torque of the screw 70 will be more accurate, which is its advantage. However, if the fixing member 75 is assembled by external force such as oil pressure, it will be more labor-intensive and require the purchase of other machines. If the fixing member 75 is bead-shaped, the fixing portion 34 and the fixing seat 74 will be tightly fitted. 4 is slightly larger than the outer diameter of the fixing member 75, that is, the three are loosely fitted, and the fixing member 75 is directly placed in the holes of the fixing portion 34 and the fixing seat 74 without the need for external force. This is its advantage, but there will be tolerances after the second body 30 and the fixing seat 74 are assembled. When the screw 70 is rotated, there will be a disadvantage of tolerance in adjusting the torque, which leads to another disadvantage. The fixing member 75 uses a tip body or a bead body, which has its own disadvantages and cannot have the best of both worlds.
[0005] 2. The screw 70 and the fixing seat 74 are assembled and then accommodated in the second body 30. The fixing member 75 is then accommodated on the fixing portion 34 and the fixing seat 74. At this time, two hands need to press the two fixing members 75 at the same time to easily assemble the second body 30 and the fixing seat 74 with the third body 60. It is more troublesome to use two hands during assembly. If there are three fixing members 75, assembling the fixing members 75 is even more troublesome.

[0054] 2. After the fixing member 32 is assembled, the first buckle 40 is assembled on the first annular groove 24. The fixing member 32 can be restrained by the first buckle 40 and will not fall out of the first fixing portion 23 and the second fixing portion 312. The second body 20, the locking assembly 30 and the plurality of fixing members 32 are then more easily assembled in the receiving groove 11.
[0055] 3. The first buckle 40 is buckled onto the second body 20 and the fixing member 32 . The fixing member 32 is restricted by the first buckle 40 and cannot fall out. The first buckle 40 has the effect of restricting the fixing member 32 .
[0056] 4. The locking member 31 is in the form of a single component, which has the advantage of low processing cost. Alternatively, the locking member 31 can be directly formed by injection molding and then the second fixing portion 312 can be drilled.
[0057] 5. The first washer 34 of the locking assembly 30 pushes the second body 20 toward the driving portion 21, so that the first surface 54 abuts against the fixing member 32. The fixing member 32 is then clamped between the first surface 54 and the second surface 55. The first buckle 40 presses against the multiple fixing members 32. The fixing member 32 is restricted by the first buckle 40, the first surface 54, and the second surface 55 and cannot escape from the first fixing portion 23 and the second fixing portion 312. The second body 20 and the locking assembly 30 have a better assembly structure.

Under the elastic action of the first washer, the second body is displaced toward the driving portion, or the locking member is displaced further outward, that is, the second body and the locking member are pushed apart from each other, so that the fixing member is against the first surface and the second surface. The fixing member is clamped between the first surface and the second surface, so that the gap between the second body and the locking member is eliminated.
2. The torsion structure according to claim 1, wherein: in, The first body is configured to rotate to adjust the torque value of the torque structure. The first body is configured to be held by hand. The accommodating groove may or may not penetrate the first body and is in the shape of a hollow circular groove. The second body is in the shape of a round rod and is pivotally mounted to the first body or fixedly mounted to the first body. The elastic member is a spring structure.
3. The torsion structure according to claim 1, wherein: in, The second body is provided with a display group, and the display group has a shifting function to display the torque value of the torsion structure.
4. The torsion structure according to claim 1, wherein: in, The driving part is assembled at one end of the second body and protrudes from the first body. The driving part is a ratchet wrench structure, a box wrench structure or an open-end wrench structure with a four-cornered head. There are two first fixing parts, and the two first fixing parts are symmetrical.
5. The torsion structure according to claim 1, wherein: in, The outer circumference of the second body is provided with a first annular groove, which is in communication with the multiple first fixing parts. The first annular groove is located on one side of the first fixing part and is in the shape of a concave arc annular groove. A first buckle is provided and the first buckle assembly is arranged at the first annular groove. The first buckle is pressed against the multiple fixing parts to prevent each fixing part from falling out of each first fixing part. The first buckle is pressed between the first body, the second body and the fixing part. The first buckle is in the shape of a metal ring and has an inward buckle elasticity.
