[0026] A clamping device is provided on the lower surface of the second support 6 , and the clamping device includes a driving rod 7 , one end of which is fixedly connected to the lower surface of the second support 6 .

[0027] The other end of the driving rod 7 passes through and extends to the lower surface of the test bench body 1. The other end of the driving rod 7 is fixedly connected to a pressing block 71. The outer surface of the driving rod 7 is movably sleeved with a supporting spring 72. One end of the supporting spring 72 is fixedly connected to the lower surface of the test bench body 1. The other end of the supporting spring 72 is fixedly connected to the upper surface of the pressing block 71. The supporting spring 72 drives the driving rod 7 to reset and move through the cooperation of the pressing block 71. The upper surface of the test bench body 1 is provided with symmetrically distributed travel grooves 73. The upper surface of the slider 3 is fixedly connected to a moving block 74. The travel groove 73 serves to limit and guide the moving travel of the moving block 74. One end of the moving block 74 passes through the travel groove 73 and extends to the upper surface of the test bench body 1. One side surface of the moving block 74 is fixedly connected to a mounting block 75.

[0028] A rotating rod 76 is installed on the lower surface of the mounting block 75 through a bearing, and one end of the rotating rod 76 is fixedly connected to a rotating block 77. The rotating rod 76 is used to position and rotate the rotating block 77 through the cooperation of the bearing. The upper surface of the rotating block 77 is provided with symmetrically distributed positioning grooves 78, one end of the rotating block 77 is fixedly connected to an arc clamp 79, and the other end of the rotating block 77 is fixedly connected to a plane clamp 710.

The reset elastic force of the reset spring 714 drives the positioning rod 712 to reset and move through the pull block 713.

[0029] Working steps

[0030] Step 1, when testing the circular insulating member, the pressing block 71 is pressed to squeeze and contract the supporting spring 72, and at the same time drive the driving rod 7 to move, and the movement of the driving rod 7 drives the two swinging rods 5 to swing through the second support 6, and the swinging of the swinging rod 5 drives the slider 3 to slide in opposite directions through the first support 4, thereby driving the two arc-surface clamps 79 to move in opposite directions through the moving block 74 and the mounting block 75, at this time, the insulating member to be tested is placed at the center of the test bench body 1, and then the pressing block 71 is released, and the pressing block 71 is driven to reset and move by the elastic force of the supporting spring 72, thereby driving the second support 6 to descend and reset and move through the driving rod 7, and the descending movement of the second support 6 causes the two sliders 3 to move relative to each other through the cooperation of the swinging rod 5 and the first support 4, thereby driving the two arc-surface clamps 79 to move relative to each other through the moving block 74 and the mounting block 75 and fixing the insulating member;

[0031] Step 2. After the test is completed, continue to press the pressing block 71 to disengage the arc clamp 79 from the fixation on the insulating part. At this time, remove the insulating part after the test and replace it with the insulating part to be tested for testing. When it is necessary to test the square insulating part, first drive the positioning rod 712 to move up through the pull block 713 to disengage one end of the positioning rod 712 from the positioning groove 78. At this time, the reset spring 714 is stretched, and then the rotating block 77 is driven to rotate one hundred and eighty degrees through the cooperation of the rotating rod 76. Finally, release the pull block 713, and the elastic force of the reset spring 714 drives the positioning rod 712 to insert into the positioning groove 78 to limit the rotating block 77 after rotation.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
