[0022] Among them, the top ring 103 is located above the base plate 101, one end of the surrounding rod 104 passes through the corresponding threaded hole 116 and is located in the corresponding groove 115, the threaded rod 105 is fixedly connected to the upper end of the surrounding rod 104, and the threaded rod 105 is threadedly adapted to the threaded hole 116, the fixed plate 110 is fixedly connected to the upper end of the threaded rod 105, the shell 106 is fixedly connected to the lower end of the top ring 103, one end of the limiting rod 107 passes through the shell 106 and is adapted to the corresponding limiting hole 114, the ring 109 is fixedly sleeved on the outer wall of the limiting rod 107 and is located inside the shell 106, the two ends of the spring 108 are respectively fixedly connected to the inner wall of the shell 106 and the ring 109, and the lower end of the suspension rod 102 is fixedly connected to the upper end of the base plate 101. When the surrounding rod 104 is damaged and needs to be replaced, the limiting rod 107 is pulled to disengage the limiting rod 107 from the limiting hole 114, and then the fixing plate 110 is rotated to drive the threaded rod 105 and the surrounding rod 104 to rotate, so that the threaded rod 105 is disengaged from the threaded hole 116, and then the fixing plate 110 is pulled upward to disengage the surrounding rod 104 from the groove 115, so that the threaded rod 105 and the surrounding rod 104 are pulled out from the threaded hole 116. When reinstalling, only the limiting rod 107 is pulled first, and then the surrounding rod 104 is passed through the corresponding The threaded hole 116 is then located in the corresponding groove 115, and then the threaded rod 105 is rotated to make the threaded rod 105 fit with the threaded hole 116, and then the limiting rod 107 is loosened. Under the elastic force of the spring 108, the limiting rod 107 is inserted into the corresponding limiting hole 114, thereby limiting the fixing plate 110 to prevent it from rotating, causing the threaded rod 105 to be out of fit with the threaded hole 116. As a result, the staff can quickly disassemble and replace the damaged surrounding rod 104, so that the safety of the use of the device is effectively guaranteed.

[0023] Secondly, the handle 111 is fixedly connected to the limiting rod 107 and is located at the lower end of the limiting rod 107.

When reinstalling, only the first pull The limiting rod 107 is moved, and then the surrounding rod 104 passes through the corresponding threaded hole 116 and is located in the corresponding groove 115. The threaded rod 105 is then rotated to make the threaded rod 105 fit with the threaded hole 116. The limiting rod 107 is then loosened. Under the elastic force of the spring 108, the limiting rod 107 is inserted into the corresponding limiting hole 114, thereby limiting the fixing plate 110 to prevent it from rotating, which causes the threaded rod 105 to be out of fit with the threaded hole 116. In this way, the staff can repair the damaged surrounding rod 104. The quick disassembly and replacement effectively ensures the safety of the device. The setting of the handle 111 makes it more convenient for the staff to pull the handle 111 to drive the limit rod 107 to move, thereby improving the convenience of operation. The setting of the chamfered surface 117 makes it unnecessary to pull the limit rod 107 first when reinstalling the surrounding rod 104. It is only necessary to squeeze the chamfered surface 117 through the side wall of the corresponding limit hole 114 to push the limit rod 107 to move downward. When the threaded rod 105 is adapted to the threaded hole 116, the spring 108 Under the action of the elastic force, the limit rod 107 will return to its original position and adapt to the corresponding limit hole 114, thereby reducing the operating procedures of the staff and making the staff more relaxed. The setting of the top cover 113 can prevent surrounding debris from falling and hitting the fixed plate 110, thereby damaging the fixed plate 110 and reducing the service life of the device. The setting of the soft pad 112 can protect the outer wall of the shell 106 to prevent the debris and the surrounding stone walls from causing friction damage to the shell 106 during the lowering of the device, thereby reducing the service life of the shell 106.
