The pawl 4 is arranged on the clamping seat 1, and specifically, the pawl 4 is rotationally connected in the block groove 103 through a third rotating shaft 15 and is located above the force applying segment 201; by rotating the pawl 4 clockwise, the pawl 4 abuts against the force applying segment 201, so that the pawl 4 can rotate around the third rotating shaft 15, the force applying segment 201 is pressed downward, the clamping segment 202 rotates around the first rotating shaft 6, and the clamping segment 202 is lifted upward to release the pressing effect of the clamping segment 202 on the pressing plate 14. The pawl 4 can also be provided in a pressing structure, by pressing the pawl 4, the pawl 4 is close to or away from the first end of the clamping block 2, that is, the force applying segment 201 is lifted or pressed, the clamping segment 202 rotates around the first rotating shaft 6, and the clamping segment 202 presses the pressing plate 14 downward or the clamping segment 202 is lifted upward to release the pressing effect of the clamping segment 202 on the pressing plate 14. The elastic member 3 is a spring.

[0064] As an example, the adjusting assembly 5 is arranged on the first end of the clamping block 2 and is in contact with the elastic member 3; by arranging in this way, according to actual requirements, the position of the adjusting assembly 5 is adjusted, the compression amount of the elastic member 3 can be accurately controlled (for example, when the adjusting assembly 5 is lowered to the lowest, the compression amount of the elastic member 3 is the largest, and vice versa, the compression amount of the elastic member 3 is the smallest), so that the lifting force of the elastic member 3 applied to the part at the first end of the clamping block 2, that is, the force applying segment 201, is adjusted, the pressing force of the clamping segment 202 on the pressing plate 14 is changed, and then multi-grade pressing force is realized to accurately adjust the pressing force of the pressing plate 14, so as to avoid that the pressing force of the pressing plate 14 is too large or too small to affect the use of the equipment; and the structure of the jaw assembly in the example is simple, the processing difficulty is low, and it is beneficial to large-scale promotion.

[0065] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
