The push-pull assembly 3 is provided with a push ring 31 positioned between the two driving ends 21, and the contact position between the peripheral surface of the push ring 31 and the inclined surfaces 211 of the two driving ends 21 is adjusted by changing the relative height between the push ring 31 and the two driving ends 21, so that the pretightening force between the two limiting ends 23 and the restoring spring 4 is adjusted.
In order to drive the push ring 31 to move, the push-pull assembly 3 further comprises a guide rod 33 and a threaded sleeve 32, and the push ring 31 is sleeved on the threaded sleeve 32. The guide rod 33 is threaded and matched with the threaded sleeve 32, and the lower end of the guide rod 33 is fixedly arranged at the closed end of the mounting frame 11. A handle 34 perpendicular to the guide rod 33 is arranged at the upper end of the threaded sleeve 32, and the handle 34 is rotated to drive the threaded sleeve 32 to rotate relative to the guide rod 33, and simultaneously the threaded sleeve 32 moves along the axial direction of the guide rod 33, so that the purpose of changing the relative height between the push ring 31 and the two limiting ends 23 is achieved. In this embodiment, in order to avoid the problem that once contact occurs between the lower end of the screw sleeve 32 and the upper surface of the closed end, the push ring 31 is mounted on the lower end of the screw sleeve 32, thereby affecting the fit between the push ring 31 and the driving end 21. And the push ring 31 and the threaded sleeve 32 are relatively fixed or relatively movable, so that the cooperation between the push ring 31 and the limiting end 23 is not affected.
In order to reduce space occupation, the closed end of the mounting frame 11 is provided with a yielding groove 111 obliquely downwards towards two sides, a hinge shaft 15 is mounted between two groove walls of the yielding groove 111, an inflection point 24 is formed between a connecting part 22 for connecting a driving end 21 and a limiting end 23 and the driving end 21 on the clamping arm 2, the inflection point 24 is in contact with the groove bottom of the yielding groove 111, and a through hole corresponding to the inflection point 24 of the clamping arm 2 is matched with the hinge shaft 15 to realize the hinge of the clamping arm 2 on the clamp 1.
In order to enable the limit end 23 to clamp the return spring 4, two implementations are provided in this embodiment:
1. the length and radian change of the connecting part 22 of the clamping arm 2 are enough to enable the contact surface of the limiting end 23 positioned at the lower end of the connecting part 22 and the restoring spring 4 to be matched with at least the arc-shaped inner wall of the opening frame 12 to hold most of the restoring spring 4 along the circumferential direction.
2. The length of the connecting portion 22 of the clamping arm 2 is at least enough to enable the opening frame 12 and the two limiting ends 23 to be matched with each other to clamp half of the restoring spring 4 in the circumferential direction, and meanwhile the contact surface of the contact end and the restoring spring 4 slightly protrudes out of the arc-shaped inner wall surface of the opening frame 12, so that the restoring spring 4 is clamped.
In fig. 1 and 2, the 1 st implementation manner is shown, and considering the processing difficulty, the opening frame 12 is an arc plate formed by integrally bending, the connecting portion 22 of the corresponding clamping arm 2 is an arc section attached to the arc plate, and the limiting end 23 at the lower end of the connecting portion 22 is matched with the opening frame 12 to clamp the restoring spring 4. Meanwhile, in view of the matching relationship between the limiting ends 23 and the restoring springs 4, in order to increase the matching tightness between the limiting ends 23 and the restoring springs 4, the opposite surfaces of the two limiting ends 23 are processed into arc-shaped surfaces, and the contact area between the limiting ends 23 and the restoring springs 4 is increased.
The use process of the embodiment is as follows:
the handle 34 is rotated to enable the thread bush 32 to move downwards along the axial direction of the guide rod 33, the push ring 31 arranged on the thread bush 32 moves downwards along with the thread bush and changes the relative height between the push ring 31 and the transmission end 21, and the purpose of adjusting the contact position of the push ring 31 and the transmission end 21 is achieved through the change of the relative height between the push ring 31 and the transmission end 21.
In the process that the push ring 31 drives the transmission end 21 to rotate around the hinge shaft 15, the two limiting ends 23 are mutually close until the restoring spring 4 is clamped, so that the restoring spring 4 is clamped by being matched with the arc-shaped inner wall of the opening frame 12, and the purpose of limiting the restoring spring 4 in the clamp 1 is achieved.
The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
