In the utility model, when using the equipment, the user connects the crane with the surface of the connecting block, then places the equipment on the track, then starts the equipment wheel to rotate and moves the equipment. When using the equipment, the user pulls the handle, and then the handle moves to drive the connecting rod to move, and then the connecting rod moves to drive the pull rod to move. When the pull rod moves, it disengages from the inside of the slot, and when the pull rod moves, it drives the first spring to displace and deform to generate elastic force, and then the connecting plate loses its restraint. By setting a protective device, the alarm light is effectively protected, which plays a role in protecting the alarm light.

[0015] 2. In the utility model, by providing a buffer device, when the device is in use, when the user starts the device to move and collides with an external object, the contact block contacts the external object, and then the baffle is moved, and the movement of the baffle drives the sliding rod to move. When the baffle moves, the sliding ring is moved, and the movement of the sliding ring drives the second spring to deform and generate elastic force, which then buffers the contact block. By providing a buffer device, the connecting frame is effectively buffered, which plays a role in buffering the device, reducing the risk of damage to the device due to the high speed when the device is in use and running.

[0024] In this embodiment: the protective device 6 is arranged on the surface of the alarm light 5, and the protective device 6 includes a connecting plate 61 and a protective cover 62. The connecting plate 61 is arranged on the surface of the alarm light 5, and the protective cover 62 is fixedly connected to the surface of the connecting plate 61. A pull groove 63 is opened on the side of the alarm light 5, and a card groove 64 is opened on the side of the connecting plate 61. The alarm light 5 is a high temperature resistant lamp.
[0025] Specifically, a pull rod 65 is slidably connected to the inner wall of the pull groove 63 , and one end of the pull rod 65 is fixedly connected to the inner wall of the clamping groove 64 .
[0026] In this embodiment, the groove 63 provided on the side of the warning light 5 can be well adapted to the pull rod 65 , and the pull rod 65 can slide smoothly inside the groove 63 , which can effectively reduce the shaking of the pull rod 65 when moving.

When the baffle plate 73 moves, the slip ring 75 is moved, and the movement of the slip ring 75 drives the second spring 76 to move and deform to generate elastic force, and then the contact block 74 is buffered. By setting the buffer device 7, the connection frame 1 is effectively buffered, which plays a role in buffering the device, reducing the risk of the device being damaged due to improper operation of the user during use and operation, resulting in a high speed of the device and easy rapid collision with foreign objects. The buffer device can provide a certain buffering protection for the device, thereby improving the practicability of the device.
