The above components are described in detail below.

The positioning seat 1, the whole of positioning seat 1 is level, and positioning seat 1 is suitable for installing on a horizontal working face, is suitable for installing on the positioning seat 1 and decides clamp assembly 2 and move clamp assembly 3.

The center of the positioning seat 1 is provided with a guide groove 11 along the length direction, and the guide groove 11 penetrates through the thickness direction of the positioning seat 1. The bottom of the positioning seat 1 is also provided with a plurality of limiting clamping grooves 12, and the limiting clamping grooves 12 are communicated with the guide grooves 11.

The movable clamp assembly 3, the movable clamp assembly 3 is arranged on the positioning seat 1, and the movable clamp assembly 3 is suitable for sliding along the length direction of the positioning seat 1 so as to be close to or far away from the fixed clamp assembly 2. Specifically, the movable clamp assembly 3 is provided with a clamping piece 31, one end of the clamping piece 31 is detachably connected with the movable clamp assembly 3, and the other end of the clamping piece 31 penetrates through the guide groove 11, so that the clamping piece 31 can slide along the guide groove 11, and when the clamping piece 31 is relatively fixed with the movable clamp assembly 3, the clamping piece 31 can slide along the guide groove 11 to drive the movable clamp assembly 3 to synchronously slide. The clamping piece 31 can be clamped into the limiting clamping groove 12, so that the clamping piece is clamped with the positioning seat 1, and the relative positions of the movable clamp assembly 3 and the positioning seat 1 are fixed.

In order to achieve the above effect, the clamping piece 31 is provided with a limiting clamp 311, and the limiting clamp groove 12 is adapted to any one of the limiting clamp 311. The clamping piece 31 drives the movable clamp assembly 3 to slide along the guide groove 11 until the movable clamp assembly 3 is matched with the fixed clamp assembly 2 to clamp a workpiece, the clamping piece 31 can be clamped into the corresponding limiting clamping groove 12 through the limiting clamping head 311 to finish the relative fixation of the clamping piece 31 and the positioning seat 1, and then the clamping piece 31 is fixed with the movable clamp assembly 3, so that the relative fixation of the clamping piece 31 and the movable clamp assembly 3 is realized, and finally the relative fixation of the movable clamp assembly 3 and the positioning seat 1 is realized.

In order to realize orderly adjustment of the clamping piece 31 and the limiting clamping groove 12, the limiting clamping groove 12 is uniformly arranged along the length direction of the guide groove 11. By the arrangement, the distance that the clamping piece 31 needs to move when being clamped into each stage of limiting clamping groove 12 is the same.

The structure of the movable clamp assembly 3 is specifically described below, the movable clamp assembly 3 includes a movable clamp seat 32 and a movable clamp head 33, and the movable clamp head 33 is fixedly connected with the movable clamp seat 32. The clamping piece 31 is detachably connected with the movable clamping seat 32. The movable clamp assembly 3 is engaged with the fixed clamp assembly 2 by the movable clamp 33 to clamp the workpiece.

It should be noted that, compared with the clamp for the bench worker, the contact surface of the clamp shown in this embodiment is larger, and a transverse groove or a longitudinal groove can be arranged on the larger contact surface to adapt to the workpiece, so as to achieve a better positioning effect, however, the positioning of the clamp is one-stage adjustment, and no transition exists between each stage, so that the clamp can clamp only one workpiece or workpieces with the same adjustment distance as each stage, and cannot position workpieces with various sizes freely. Therefore, the above-described problem is solved by providing the clip assembly 2 in the present embodiment.

One end of the adjusting spring 24 is connected with the fixed clamping head 23, and the other end is connected with the fixed clamping seat 22. With the above arrangement, when the movable chuck 33 pushes the workpiece to abut against the fixed chuck 23, the workpiece can further push the fixed chuck 23, so that the fixed chuck 23 pushes the adjusting spring 24 to contract.

The structure solves the problem of adapting to workpieces with different sizes, but the two ends of the clamping workpiece are required to be reliably fixed, so that the clamping assembly 2 is provided with a plurality of clamping pieces 21 for solving the fixing effect of the fixed clamping head 23, and the clamping pieces 21 are detachably connected with the fixed clamping assembly 2. Specifically, when the workpiece is placed between the fixed clamp assembly 2 and the movable clamp assembly 3, the movable clamp assembly 3 pushes the workpiece to squeeze the fixed clamp assembly 2, so that the fixed clamp assembly 2 is contracted to the clamping piece 31 to be clamped with the positioning seat 1, and the clamping piece 21 clamps the fixed clamp assembly 2. The clamping member 21 includes a threaded post 211 and a hand wheel 212 disposed at one end of the threaded post 211. The threaded post 211 is in threaded connection with the fixed holder 22.
