According to the button arrangement on the maintenance box under test of different models, the number and relative position relationship of the button action mechanism 1, the push-pull type emergency stop button action mechanism 2, the conversion switch action mechanism 3, and the clamping action mechanism 4 are adjusted. The two groups of maintenance box test devices are connected to the switching switch 11 for switching the two groups of maintenance box test devices through control circuits. There are two groups of clamping action mechanisms 4, which are diagonally arranged at the corners of the maintenance box under test.

[0032] See Figure 4 The button action mechanism 1 includes a jig cylinder 6, a button push rod 7 and a cylinder bracket 8. The driving shaft of the jig cylinder 6 is vertically downwardly arranged above the button of the inspection box to be tested through the cylinder bracket 8. The button push rod 7 is fixedly connected to the driving shaft and is coaxially arranged with the button of the inspection box to be tested. A buffer pad 701 is arranged at the bottom end of the button push rod 7.

[0033] See Figure 5 The push-pull emergency stop button actuating mechanism 2 includes a jig cylinder 6, a button push rod 7 and a cylinder bracket 8. The driving shaft of the jig cylinder 6 is vertically downward through the cylinder bracket 8 and is arranged directly above the emergency stop button of the maintenance box under test. The button push rod 7 is fixedly connected to the driving shaft and is coaxially arranged with the emergency stop button of the maintenance box under test. A push-pull fastener 201 is arranged at the end.

[0034] See Figure 6 The switch action mechanism 3 includes a slide cylinder 9, a rotary cylinder 10 and a cylinder bracket 8. The driving end of the slide cylinder 9 is vertically downwardly installed on one side of the maintenance box to be tested through the cylinder bracket 8.

[0037] The working principle of the present invention is as follows: the tester selects the relative test device by switching the switch 11, and scans the QR code of the maintenance box to be tested by the scanner connected to the host computer 5. The system identifies the test model, displays the model to be tested and the content to be tested, and the tester determines whether the test model and content are correct. If correct, put it into the test device and start testing. The clamping action mechanism 4 clamps the maintenance box to be tested, and tests according to the test procedure, drives each cylinder to work, exhausts all combinations of switches and buttons, and compares the circuit logic relationship and voltage and current values ​​of each combination with the standard. If qualified, it will be displayed as qualified. If different from the standard, it will be displayed as unqualified, and the fault point will be displayed, which is convenient for the tester to feedback and find the cause. Each cylinder has a position action sensor 12, which timely feedbacks the action status to avoid the influence of malfunction on the test results. The cylinder action is controlled by the control circuit and the host computer 5.
