It plays a vital role in preventing passengers from getting pinched when entering and exiting the elevator. In order to ensure the safe operation of the elevator, professionals are required to regularly inspect the elevator performance.

It also has good elasticity to avoid the situation where the elevator door collides with it when it is closed and causes the elevator door to collide with it.
[0028] In the disclosed embodiment, the upper wall and the lower wall of the detection rod support sleeve 1 are respectively rotatably connected with two directional rollers 101, and the directional rollers 101 are rollingly connected to the outer surface of the test strut 6. A positioning screw hole 102 is vertically opened in the middle of the upper surface of the detection rod support sleeve 1, and a positioning bolt 103 is spirally connected inside the positioning screw hole 102; under normal conditions, when the test struts 6 are in a folded and stored state, the two test struts 6 are retracted inwardly, and the positioning bolt 103 is spirally connected inside the positioning screw hole 102, and the inner end of the positioning bolt 103 extends to the inside of the strut positioning socket 605, so as to limit the test strut 6 and keep the test strut 6 in a retracted state.
[0029] In the disclosed embodiment, a reset coil spring 201 is provided inside the support sleeve elastic connecting tube 2, the outer end of the reset coil spring 201 is fixedly connected to the inner side wall of the support sleeve elastic connecting tube 2, the inner end of the reset coil spring 201 is fixedly connected to the front end of the shaft of the synchronous gear column 4, the inner surface of the test strut 6 is provided with a groove body, and the inner surface of the groove body of the test strut 6 is provided with a strut push tooth 601, the strut push tooth 601 is meshed and connected to the synchronous gear column 4 to form a gear rack transmission; under normal conditions, when the test tool is in the unfolded state, a torque is applied to the synchronous gear column 4 through the action of the reset coil spring 201, and an outward pushing force is applied to the test strut 6 through the gear rack transmission of the synchronous gear column 4 and the strut push tooth 601, so that the detection tool remains in the unfolded state.
[0030] Embodiment 2, on the basis of embodiment 1, the inner end of the test strut 6 is bent and provided with a strut limiting end 602, the outer end of the test strut 6 is fixedly connected with an end support plate 603, and the outer surface of the end support plate 603 is fixedly connected with a buffer gasket 604 made of rubber material; through the action of the strut limiting end 602, the movable range of the test strut 6 is limited, and through the setting of the end support plate 603 and the buffer gasket 604, the elevator door touches the buffer gasket 604 during the closing process, which can play a buffering role, avoiding collision and scratches on the elevator door and affecting the normal use of the elevator.
