[0025] The working principle of this utility model:

[0026] By setting an adjustment base 3 and a pressing cross plate 13 with positioning workpieces, the swing arm 16 is clamped into the inside of the synchronization groove 15 and then locked by a bolt. After the two swing arms 16 are installed, the linkage column 11 is inserted into the inside of 17, so that the pressing cross plate 13 is sleeved on the outside of the linkage column 11, and then the adjusting nut 12 is rotated and installed on the top of the linkage column 11.

Since the two swing arms 16 are movably installed between the corresponding synchronization grooves 15, the distance between the two swing arms 16 can be adjusted to expand the fixing range. At the same time, the height of the pressing cross plate 13 can be raised and lowered to adapt to the height of the workpiece. When fixing workpieces of different specifications, it can have better adjustment ability and adapt to workpieces of different specifications, which greatly improves the applicability of the device.

[0027] By providing a placement plate 8 for placing the workpiece to be processed, after the two lifting devices 6 are inserted and installed in the installation cavity 5 opened inside the adjusting cavity 4, the upper end of the lifting device 6 is extended and the placement plate 8 is moved to the surface of the adjusting cavity 4, so that the upper ends of the two lifting devices 6 are connected and installed on the lower surface of the placement plate 8 and locked, and then the overall lifting height of the placement plate 8 is controlled by controlling the extension and contraction of the two lifting devices 6. After the two adjustment bases 3 are clamped in the guide rail 7, the two adjustment bases 3 are respectively located on the left and right sides of the placement plate 8. After the two adjustment bases 3 are pushed close to each other and clamped into the embedded slot 9, when the workpiece is fixed, the workpiece is first pressed and fixed by the top of the two sets of swing arms 16, and at the same time, the two lifting devices 6 are started to extend, so that the entire placement plate 8 drives the workpiece to rise and clamp the workpiece. When the device is in use, the clamping pressure can be adjusted according to the material of the workpiece to prevent damage to the workpiece.
