In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture.

[0003] The existing Chinese patent "A positioning fixture for automated equipment" with the announcement number CN216829058U proposes a fixture that facilitates real-time positioning and fixing when the PCB board is flipped. However, the main components for fixing the PCB board are the second push spring and the third push spring. When the PCB board is subjected to pressure, the second push spring and the third push spring will be pushed in the opposite direction, which leads to poor stability of the device clamping the PCB board during use, affecting the effect of the PCB board. There are certain shortcomings. For this reason, we propose an automatic positioning fixture device. Utility Model Content
