[0023] like Figure 1-3As shown, the bottom of the test bench 1 is fixedly connected to the support legs 2 near the corner. There are four sets of support legs 2 arranged in an array. The gantry frame 3 is fixedly connected to the test bench 1. The hydraulic cylinder 4 is connected to the gantry frame 3 by bolts. The output end of the hydraulic cylinder 4 is fixedly connected to the pressure plate 5. The pressure plate 5 is fixedly connected to the guide rod 6. There are two sets of guide rods 6 arranged symmetrically. The upper end of the gantry frame 3 has through holes that are compatible with the guide rods 6. The control panel 7 is connected to the gantry frame 3 by bolts. The control panel 7 has control buttons and a display screen on its outer side. The control panel 7 has a control circuit board and a battery inside. The receiving plate 8 and the placement plate 10 are connected by a replacement component 11, which facilitates the testing of hydraulic components.

[0024] like Figure 2-4 As shown, the number of adapter slots 111 is equal to the number of placement plates 10, and the two are compatible. The adapter slots 111 are connected to the card slots 112, the card slots 112 are compatible with the card blocks 113, the card blocks 113 are fixedly connected to the placement plates 10, the moving holes 114 are connected to the adapter slots 111, the electric push rod 115 is connected to the receiving plate 8 by bolts, the electric push rod 115 and the distance sensor 117 are both electrically connected to the control panel 7, the output end of the electric push rod 115 is fixedly connected to the positioning post 116, the positioning post 116 is compatible with the moving holes 114, and the positioning post 116 is compatible with the positioning slots 118, which facilitates the automatic disassembly and installation of the placement plates 10.
