[0026] A sliding ball groove 81 is provided at one end of the positioning rod 7, and a rolling ball 82 is slidably sleeved on the inner wall of the sliding ball groove 81. The rolling ball 82 plays the role of limiting rolling in the sliding ball groove 81, so that when the cabinet door 2 is opened, the friction with the inner top wall of the cabinet body 1 is reduced by rolling the rolling ball 82. A return spring 83 is movably sleeved on the outer surface of the positioning rod 7, and one end of the return spring 83 is fixedly connected to the lower surface of the guide block 6, and the other end of the return spring 83 is fixedly connected to the upper surface of the annular limit block 8. The elastic force of the return spring 83 drives the positioning rod 7 to rise and reset through the cooperation of the annular limit block 8. A semi-circular disk 84 is fixedly connected to the front side of the cabinet body 1, and the upper surface of the semi-circular disk 84 is provided with limiting holes 85 distributed in a circular array. The inner wall of one of the limiting holes 85 is movably plugged into one end of the positioning rod 7, and the inner bottom wall of the mounting cavity 5 is fixedly mounted with a first mounting seat 86.

[0027] The inner walls on both sides of the first mounting seat 86 are both installed with first guide wheels 87 through bearings, the inner wall on one side of the mounting cavity 5 is fixedly installed with a second mounting seat 88, the inner walls on both sides of the second mounting seat 88 are both installed with second guide wheels 89 through bearings, and the other end of the positioning rod 7 is fixedly connected with a pull rope 810, and the outer surfaces of the pull rope 810 are in rolling contact with the outer surfaces of the first guide wheel 87 and the second guide wheel 89 respectively, and the first guide wheel 87 and the second guide wheel 89 play a role in guiding the moving direction of the pull rope 810.

[0029] Working principle: Step 1, when opening the cabinet door 2 for maintenance, first hold the driving handle 3, and at the same time, insert the middle finger into the pull ring 814, then open the cabinet door 2 by the driving handle 3, and release the pull ring 814 after opening it to a suitable angle. At this time, the elastic force of the reset spring 83 drives the positioning rod 7 to move upward, and at this time, one end of the positioning rod 7 is inserted into one of the limiting holes 85, thereby limiting the opened cabinet door 2;

[0030] Step 2. After the inspection is completed, the stop block 813 is moved through the pull ring 814, and the stop block 813 drives the connecting rod 812 to move. The connecting rod 812 drives one end of the pull rope 810 to move through the movable block 811. The pull rope 810 drives the positioning rod 7 to move downward through the cooperation of the first guide wheel 87 and the second guide wheel 89. The downward movement of the positioning rod 7 drives the reset spring 83 to stretch through the annular limit block 8, so that the positioning rod 7 is out of the limit of the limit hole 85, and then the cabinet door 2 can be closed by driving the handle 3.
