It provides the control of the current required by all components in the power supply. The power of the power supply, whether the current and voltage are stable, are directly affected by the power control board. A fixture is used when testing the voltage control board. The fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electrical control and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement. Therefore, a voltage control board test fixture is needed.

When operators test the voltage control board, they often use the corresponding voltage control board test fixture. Although the existing fixture can achieve the purpose of testing, it often requires manual feeding during actual use.

A moving plate 10 is fixedly installed on the top of the slider 9, and the round rod 8 and the slider 9 can limit the running trajectory of the moving plate 10. A push rod 11 is hinged between the moving plate 10 and the sliding sleeve 5, and a storage groove 12 is opened on the top of the moving plate 10. The storage groove 12 can prevent the voltage control board from being placed. A vertical plate 13 is fixedly installed on the top of the bottom plate 1, and a horizontal plate 14 is fixedly installed on the top of the vertical plate 13. A limiting groove 15 is opened on one side of the vertical plate 13, and a limiting rod 16 is fixedly installed inside the limiting groove 15. The surface of the limiting rod 16 is movably sleeved with a limiting block 17, and the outer surface of the limiting block 17 is movably connected to the inner surface of the limiting groove 15.

A connecting rod 18 is fixedly installed on one side of the limit block 17, and a mounting frame 19 is fixedly installed on one side of the connecting rod 18. A pneumatic cylinder 22 is fixedly installed on the top of the cross plate 14, and the output end of the pneumatic cylinder 22 passes through the cross plate 14 and is fixedly connected to the top of the mounting frame 19.
