Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5This utility model provides an embodiment of a workbench for output voltage testing, comprising a table body 1. The table body 1 is characterized by: a power distribution cabinet 2 fixedly connected to one side; a sliding groove 17 provided inside the table body 1; a contact 3 fixedly connected inside the power distribution cabinet 2; a wire 4 fixedly connected to the contact 3; a spring contact 5 fixedly connected inside the power distribution cabinet 2; a fixing block 6 fixedly connected inside the power distribution cabinet 2; a slider switch 7 slidably connected to the fixing block 6; a connecting shaft 8 fixedly connected to the slider switch 7; a metal block 9 fixedly connected to the end of the connecting shaft 8 away from the slider switch 7; an electromagnet 10 slidably connected to the metal block 9; the electromagnet 10 fixedly connected to the power distribution cabinet 2; an electrical circuit board 13 electrically connected to the electromagnet 10; and a contact 12 fixedly connected to one end of the spring contact 5.

[0030] Circuit board 13 has normally closed contacts 22, with two sets of normally closed contacts 22. One end of normally closed contact 22 is connected to the output terminal of diode 1 23, and the other end is connected to resistor 28. The input terminal of diode 1 23 is connected to the output terminal of diode 24, coil wristband 19, and the input terminal of diode 24 is connected to the input terminal of diode 4 26, capacitor 27, electromagnet 10, and resistor 28. One end of coil wristband 19 is connected to the input terminal of diode 3 25 and the output terminal of diode 4 26. The output terminal of diode 3 25 is connected to capacitor 27. One end of electromagnet 10 is connected to normally closed contact 22, and one end of resistor 28 is connected to normally open switch 29. One end of normally open switch 29 is connected to normally closed contact 22. 22. A motor 14 is fixedly connected inside the table body 1. A threaded rod 15 is fixedly connected to the output end of the motor 14. The end of the threaded rod 15 away from the motor 14 is rotatably connected to the table body 1. A threaded block 16 is threadedly connected through the threaded rod 15. A slide groove 17 is slidably connected to the threaded block 16. An instrument table 18 is fixedly connected to the slide groove 17. The instrument table 18 is slidably connected inside the table body 1. A voltmeter 20 is provided on the instrument table 18. There are two sets of voltmeters 20. A socket 21 is provided on the motor 14. There are two sets of sockets 21. A coil wristband 19 is snapped onto one side of the table body 1. The coil wristband 19 is electrically connected to the circuit board 13. The threaded block 16 slides in the slide groove 17. There are two sets of contact point 1 3, spring contact point 5, fixing block 6, and contact point 2 12.

[0031] Working principle: When working, the operator wears a coil wristband 19. During operation, the operator pushes the slider switch 7, which slides within the fixed block 6, pressing the spring contact 5. The spring contact 5 contacts contact 3, allowing the circuit to flow and starting the motor 14. The output of the motor 14 drives the threaded rod 15 to rotate, which in turn moves the threaded block 16. The threaded block 16 moves within the slide groove 17, pushing the instrument platform 18 to move, thus raising and lowering the instrument platform 18. This keeps the worktable clean and aesthetically pleasing when not in use. In the event of an electric shock, current flows through the coil wristband 19, generating an electric current. The current flows out from the coil wristband 19, through diode 23, capacitor 27, and diode 26 back to the slide groove 17 to form a circuit. With capacitor 27 energized, the current flows out from a set of normally closed contacts 22, through capacitor 27 and electromagnet 10, back to a set of normally closed contacts 22 to form a circuit. Electromagnet 10 is energized and immediately attracts, pulling metal block 9 to move. The movement of metal block 9 drives the connecting shaft 8 to move, which in turn drives the slider switch 7 to move. The spring contact 5 resets, the circuit is broken, and the power is cut off quickly, thus escaping the danger of electric shock for the workers and protecting their lives and health.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
