The handle 20 is generally cylindrical, and the center of the handle 20 is a coupling groove 21, which is used for the micro-adjustment part 40 to be socketed. 211 is an annular concave tooth shape, and the contact part 211 and the fine-tuning part 40 are meshed and fixed in the radial direction, and are movable and fixed in an axially detachable manner. The connecting end 22 is set for the unfixing part 30, and a conduction groove 221 is formed on both sides of the sleeve end 22; an elastic part 23 and a sleeve 24 are arranged in the coupling groove 21 of the handle 20, and the sleeve 24 is used The elastic member 23 is fitted so as to keep stable when pushing against the fine-tuning part 40 .

The unfixing part 30 is provided with a fastener 31 and a pusher 32. The fastener 31 is in the shape of a circular ring, and a positioning end 311 is formed on both sides upwards. lead angle, the firmware 31 is sleeved on the sleeve end 22 of the handle 20, and the positioning end 311 of the firmware 31 is set opposite to the conduction groove 221 of the sleeve end 22, so that the positioning end 311 can be connected with the fine-tuning part 40. The push piece 32 is generally in the shape of a circular sleeve. The push piece 32 is sleeved on the sleeve end 22 of the handle 20, and the push piece 32 is formed with a contact surface 321 on both sides of the inner diameter of the upper opening. The two abutting surfaces 321 are each a kind of slope, and the two abutting surfaces 321 are abutted against the positioning end 311 of the firmware 31, so that when the push piece 32 is pulled, the abutting surface 321 can be pushed against the positioning end 311 of the firmware 31 to push and open. combine.

The fine-tuning part 40 is connected to the joint groove 21 of the handle 20. The fine-tuning part 40 is provided with a rotating part 41 and a shaft 42. The rotating part 41 is generally in the shape of a hollow round rod, and the hollow center of the rotating part 41 is A hexagonal perforation 411, and a turning end 412 with a larger diameter is formed at one end. The turning end 412 is provided with several grooves for the user to use fingers to quickly turn and rotate. The turning piece 41 is formed with a first Limiting groove 413 and a second limiting groove 414, and form a card portion 415 in the second half, the first limiting groove 413 and the second limiting groove 414 and the positioning end 311 of the firmware 31 are used as axial movable cards Arrest, the clamping portion 415 is a ring-shaped convex tooth surface, and the clamping portion 415 is fixed radially with the contacting portion 211 of the coupling groove 21, so that the movable fixation with clutch effect can be achieved; the shaft 42 is a hexagonal The shaft 42 is in the shape of a long rod, and the shaft 42 is passed through the hole 411 of the rotating part 41 , and one end of the shaft 42 is pushed against the sleeve 24 in the handle 20 under the influence of the elastic member 23 .

Referring to Figures 6 to 8, when the utility model intends to separate and rotate the handle 20 and the fine-tuning part 40, it is only necessary to pull the pusher 32 of the unfixing part 30 to move inward, so that the contact surface 321 of the pusher 32 will The positioning end 311 of the firmware 31 is pressed and pushed away. When the positioning end 311 is opened to a certain size, the first limit groove 413 of the rotating member 41 will be released from the clamping. In this way, the fine-tuning part 40 will release the axial fixation. Simultaneously pushed by the elastic piece 23 in the handle 20, the fine-tuning part 40 is pushed outward. The abutting portion 211 is separated, the radial clamping is released, and at the same time as the radial clamping is released, the second limiting groove 414 of the rotating member 41 is displaced to the positioning end 311 of the firmware 31 and forms an axial clamping, which can achieve The relative pivoting of the handle 20 and the fine-tuning part 40 ; in this way, the user can hold the handle 20 and rotate the fine-tuning part 40 with fingers to achieve fast bolting.

When the user completes the force transition period of the bolting device and wants to turn the handle 20 to give more strength to the bolting device, he only needs to hold the handle 20 and push it in the direction of the bolting device, and the positioning end 311 of the firmware 31 is It will be pushed and stretched by the rotating part 41. When the clamping part 415 of the rotating part 41 extends into the contact part 211 of the coupling groove 21 to form radial locking, the first limiting groove 413 of the rotating part 41 is also displaced to the firmware 31 at the same time. The positioning end 311 of the locating end 311 is axially locked against it; in this way, the user can instead use the handle 20 to hold the bolt firmly.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, All still belong to within the scope of the technical solution of the utility model.
