When the upper surface of the sliding plate 6 contacts the pressure sensor 7, the single-chip microcomputer 3 executes a stop command to the cylinder 4, which is beneficial to reducing the probability of the detection device 9 and the inverter being squeezed and damaged;

[0032] Reference Figure 1 、 Figure 7 and Figure 8 In order to achieve the purpose of eliminating the need for manual selection of unqualified inverters, an L-shaped fixing plate 13 is fixedly connected to the upper surface of the conveyor 1.

When the pressure of the cylinder 4 is too large, the detection device 9 applies thrust to the sliding plate 6, and the sliding plate 6 compresses the spring 8. When the upper surface of the sliding plate 6 contacts the pressure sensor 7, the cylinder 4 is executed through the single-chip microcomputer 3 to stop the instruction.
