[0025] like Figures 1 to 6 As shown, an insulating low-voltage operating table includes a panel 1, a protective cover 6 and an annular clamping plate 601.

[0026] The protective cover 6 is U-shaped, and the protective cover 6 is fixedly provided on the panel 1. A slide bar 603 is fixedly provided on the inner side of the protective cover 6. A support frame 9 is fixedly provided on the back of the protective cover 6, and a lifting block 8 is provided on the support frame 9 through a screw 10. The lifting block 8 is threadedly engaged with the screw 10. A lighting lamp 7 is fixedly provided on the lifting block 8. An adjusting knob is provided at the top of the screw 10. The height of the lighting lamp 7 can be adjusted by driving the screw 10 to rotate by the adjusting knob. The lighting lamp 7 is provided on the top of the protective cover 6, which is conducive to the detection of electrical appliances.

[0027] A bidirectional screw 605 is rotatably mounted below the panel 1 via a first fixing plate 606. A bearing is positioned in the middle of the bidirectional screw 605, engaging a second fixing plate 607. The bidirectional screw 605 is connected to the panel 1 via the second fixing plate 607. The left and right sections of the bidirectional screw 605 have opposite thread directions. The bidirectional screw 605 is driven by a motor 609.

[0028] A positioning plate 604 is provided on the bidirectional screw 605, and the positioning plate 604 is threadedly engaged with the bidirectional screw 605. A hollow groove that cooperates with the positioning plate 604 is provided on the panel 1. After the positioning plate 604 passes upward through the panel 1, a fixing frame 610 is provided. A lug 602 is welded at the rear end of the fixing frame 610, and a through hole is provided on the lug 602 that slides with the slide rod 603 on the protective cover 6.

[0029] A circular clamping plate 601 is rotatably mounted within the fixed frame 610, engaging the end face of the appliance to be tested. A curved mounting bracket is mounted on the top of the panel 1 via four springs. Two sets of rollers are mounted within the bracket, engaging the circumference of the appliance to be tested. This reduces friction generated by the appliance during rotational testing.

[0030] When there is a protrusion on the outside of the appliance being tested, the placement rack can move downward when the protrusion of the appliance contacts the placement rack, and the spring pushes the placement rack to reset upward when the protrusion of the appliance leaves the placement rack.

[0031] Support legs are fixedly provided on the lower end surface of the panel 1, and a crossbeam is provided between the support legs.

[0032] The legs of the panel 1 are inserted into the mobile frame 2, and a connecting plate 3 is provided between the mobile frames 2. The connecting plate 3 is provided with an electric telescopic rod 4 that cooperates with the crossbeam between the legs. The electric telescopic rod 4 can adjust the height of the panel 1.

[0033] The outer sides of the legs of the panel 1 are provided with limiting blocks 5 that cooperate with the movable frame 2 .

[0034] The panel 1 is provided with a control switch 608 electrically connected to the electric telescopic rod 4 and the motor 609 .

[0035] The action process of this utility model is as follows:

[0036] Motor 609 drives the bidirectional screw 605 to rotate, thereby causing the two fixed frames 610 to move relative to each other. This movement also causes the two annular clamping plates 601 within the protective cover 6 to move relative to each other, thereby clamping the ends of the appliance under test placed on top of the rack. By rotating the annular clamping plates 601 within the fixed frames 610, the appliance under test can be rotated, facilitating testing.

[0037] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
