Detailed Description
The technical scheme of the utility model is further specifically described by the following embodiments and the accompanying drawings.
Referring to fig. 2, the easy-to-clamp ratchet clamp of the present application includes two cross-fixed bodies 4, a chuck 5 fixed on the top ends of the two bodies, a self-locking device 6 and a return spring, etc. disposed between the two bodies. The structure of the body 4 and the chuck 5 of the present application is improved over the prior art. For a specific structure, refer to the following description.
As shown in fig. 2, 3 and 4, two protruding bosses 51 extend outward from two sides of the chuck 5, and each protruding boss 51 is provided with a corresponding connecting through hole 52. The cartridge 5 is fixed to the top end of the body 4 through two connecting bores 52 by means of pins 7. As shown in FIG. 4, the inside of the chuck 5 is provided with a groove shaped like a Chinese character 'shan', two sides of the groove are provided with travel grooves 53, and the middle part of the groove is provided with a non-through hole 54. An elastic bushing member is disposed in the recess. The bushing member comprises a bushing 8 and a spring member 9. The bushing 8 is a "hill" shaped structure that matches the recess. The two ends 81 of the bush 8 are cylindrical structures (not limited to a cylindrical shape) which are inserted into the stroke grooves 53 of the corresponding sides, and the middle portion 82 of the bush 8 is inserted into the blind hole 54. The two ends and the middle part of the bush 8 are respectively connected with the inner diameters of the corresponding stroke groove and the corresponding hole. The spring element 9 is fitted over the central portion 82 of the bush 8 and is located in the hole. The bottom of the bush is arc-shaped, and the bottom of the bush is directly abutted to the top end of the body 7.
When a person applies force to the ratchet clip, the spring element 9 is compressed to store energy. When the hand is released, the self-locking device keeps the force applied by the hand through the meshing of the teeth, but the teeth cannot be meshed with the teeth all the time, when the person prepares to release the force, if the teeth are not meshed at the moment, the self-locking device moves backwards for a small distance to be meshed with the previous teeth, and at the moment (the teeth of the ratchet wheel move backwards), the spring part 9 releases the energy accumulated previously, so that the chuck 5 is clamped.
Referring to fig. 2 and 5, the body 4 of the present application is formed by connecting a first body 41 and a second body 42 through a torsion spring 10. As shown, the first body 41 is located at the upper end, and the front end of the first body 41 is connected to the chuck 5. A protruding slot 411 is disposed at the rear end of the first body 41, and first through holes are disposed on two sides of the slot 411 respectively. The second body 42 is located at the lower end, the front end of the second body 42 is provided with an extended connecting plate 421, the connecting plate 421 is provided with a second through hole, and the connecting plate 421 is inserted into the clamping groove 411. The torsion spring 10 is limited at the connection position of the connection plate 421 and the slot 411 by a fixing member. The upper end of the torsion spring 10 is clamped on the outer side of the first body 41, and the lower end of the torsion spring 10 is limited on the upper surface of the second body 42. The torsion spring 10 limits the distance of the first body 41 from the second body 42 by its own torsion force, thereby overcoming the problem of the loosening of the clamping force caused by the deformation of the plastic member.
As shown in fig. 5, the upper end of the torsion spring 10 encloses the outer wall of the first body 41 inside the torsion spring 10. The surface of the second body 42 is provided with an inward-recessed limiting groove 422, and the lower end of the torsion spring is limited in the limiting groove. When the chuck is stressed, the movement of the body 4 stresses the torsion spring 10, thereby clamping the object.
The improved structure is made from two positions of the chuck and the body, and the clamping force is increased.
The above embodiments have chosen the best mode as an example. Furthermore, it is also possible to provide only the body and the collet with the first elastic element as in the above embodiments; or the body is divided into a first body and a second body, and then the second elastic element in the above embodiment is arranged on the first body and the second body.
The above embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. All equivalent changes and modifications of the utility model that may occur to those skilled in the art are intended to be covered by the appended claims.
