All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 shows a jaw 1 according to an embodiment of the present invention, which includes a base 105, a first clamping member 102 and a second clamping member 103, wherein the first clamping member 102 and the second clamping member 103 are spaced apart from each other on the base 105, and the height of the first clamping member 102 and/or the second clamping member 103 extending from the base 105 is adjustable, so that the height of the first clamping member 102 extending from the base 105 is higher than the height of the second clamping member 103 extending from the base 105, or the height of the first clamping member 102 extending from the base 105 is lower than the height of the second clamping member 103 extending from the base 105.
The jaw 1 may be mounted as a separate part to various jigs, such as a jaw of a chuck jig. Referring to fig. 1, when the jaw 1 is applied to a chuck jig, the base 105 of the jaw 1 is arranged in a radial direction of the chuck jig, so that the first clamping member 102 and the second clamping member 103 are arranged at intervals in the radial direction of the chuck jig; the chuck holder shown in fig. 1 has two working states, referring to fig. 2, which is the first working state of the chuck holder, wherein the first clamping member 102 extends out of the base 105 to a higher height than the second clamping member 103 extends out of the base 105, the first clamping member 102 is used as a clamping action part, and can clamp a workpiece through the inner side wall or the outer side wall of the first clamping member 102, and fig. 2 shows the process of clamping the inner wall of the workpiece through the outer side wall of the first clamping member 102. Referring to fig. 3, fig. 3 shows a second working state of the chuck assembly, in which the height of the first clamping member 102 extending out of the base 105 is lower than the height of the second clamping member 103 extending out of the base 105, the second clamping member 103 is used as a clamping action part, and the workpiece can be clamped by the inner side wall or the outer side wall of the second clamping member 103, and fig. 3 shows the process of clamping the inner wall of the workpiece by the inner side wall of the second clamping member 103. Therefore, the clamping of the same clamping jaw 1 to workpieces in different shapes or different parts of the same workpiece can be realized, and the frequency of replacing the clamp in the workpiece machining process is effectively reduced.
Wherein, in order to achieve an adjustment of the relative height between the first clamping member 102 and the second clamping member 103, the first clamping member 102 can be fixedly connected relative to the base 105 and the second clamping member 103 can be movably connected to the base 105, whereby the adjustment of the relative height between the first clamping member 102 and the second clamping member 103 can be achieved by adjusting the protruding height of the second clamping member 103 relative to the base 105. It is also possible to fixedly attach second clamping member 103 with respect to base 105 and movably attach first clamping member 102 to base 105, and to adjust the relative height between first clamping member 102 and second clamping member 103 by adjusting the height of extension of first clamping member 102 with respect to base 105.

In addition, the first clamping member 102 and the second clamping member 103 can be detachably connected with the base 105 respectively, and when one clamping member needs to be used, the other clamping member can be detached.
It should be understood that the number of the above-mentioned clamping members of the jaws 1 may be greater than two, wherein each clamping member may be detachably connected to the base 105, so that when the clamping position of the workpiece needs to be changed, it can be realized by only changing different clamping members, and at this time, the clamping action portion of each jaw 1 may be more than two, that is, each jaw 1 may be adapted to clamp workpieces of at least three different shapes, thereby further reducing the frequency of changing the clamp during the processing of the workpiece.

Thus, by arranging the first mounting hole 101 and the second mounting hole 104, the height of the first clamping piece 102 and the height of the second clamping piece 103 extending out of the base 105 can be adjusted by controlling the first clamping piece 102 to extend out or retract relative to the first mounting hole 101 or controlling the second clamping piece 103 to extend out or retract relative to the second mounting hole 104, and thus the relative height between the first clamping piece 102 and the second clamping piece 103 can be adjusted.
Optionally, a first slideway 111 communicated with the first mounting hole 101 and a second slideway 106 communicated with the second mounting hole 104 are respectively formed on a side wall of the base 105;

When the rotation connection point of the transmission member 107 and the base 105 is located outside the area formed between the first slideway 111 and the second slideway 106, when the first fastening member 102 ascends relative to the base 105, the transmission member 107 drives the second driving member 108 to move upwards along the second slideway 106, and at this time, the second driving member 108 drives the second fastening member 103 to ascend.
