[0002] Metal surface treatment fixtures are tools used to fix metal workpieces during various surface treatment processes. They can ensure the accurate position of the workpiece during the treatment process so as to obtain a uniform and consistent treatment effect. The structures of existing metal workpiece surface treatment clamping devices are mostly complex and cannot play a good clamping effect, which can easily cause the metal workpiece to fall. When the other side of the metal workpiece needs to be processed, the staff needs to manually flip it over and re-fix it, which affects the efficiency of the treatment. In addition, it is impossible to fix workpieces of different sizes and shapes, affecting its applicability.

[0003] According to a metal surface treatment fixture published on the patent website (authorization announcement number: CN220680597U), the metal surface treatment fixture includes a "fixing seat, an equipment table, a placement slot", etc. to perform fixing work.

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] The fixture for metal surface treatment utilizes a fixing seat, an equipment table, a placement slot, etc. to perform fixing work. During use, the fixture is fixed by a first clamping plate and a second clamping plate.

The operation is complicated and inefficient, which affects the efficiency of the processing. Therefore, the fixture needs to be improved. Utility Model Content
