[0026] With reference to Figure 1 , Figure 5 and Figure 6 , one end of the cable 17 is provided with a hook 18, both sides of the hook 18 are provided with a fixing device 19, the fixing device 19 comprises a fixing shaft 20, the outer side of the fixing shaft 20 is provided with a fixing rod 21, the top of the fixing rod 21 is provided with a sliding block 22, the top of the sliding block 22 is provided with a sliding rod 23, the outer side of the sliding rod 23 is provided with a limiting plate 24, the outer side of the fixing rod 21 is provided with a connecting shaft 25, the outer side of the connecting shaft 25 is provided with a plastic sheet 26, the top of the sliding rod 23 is provided with a contact plate 27. In this embodiment, the fixing shaft 20 serves to facilitate the rotation of the fixing rod 21, the fixing rod 21 serves to connect the sliding plate 16, and the sliding block 22 serves to push the fixing rod 21 to rotate.

[0027] With reference to Figure 5 and Figure 6 , the limiting plate 24 and the fixing shaft 20 are fixedly connected to both sides of the hook 18, the fixing rod 21 is rotatably connected to the outer side of the fixing shaft 20, the plastic sheet 26 is clamped to the outer side of the connecting shaft 25, the sliding block 22 is slidingly connected to the outer side of the fixing rod 21, the sliding rod 23 is slidingly connected to the inside of the limiting plate 24, and the contact plate 27 is fixedly connected to the sliding rod 23. In this embodiment, the plastic sheet 26 serves to support the fixing rod 21, and the connecting shaft 25 serves to mount the plastic sheet 26.

[0028] The working principle of the present application is as follows:

[0029] In the process of using the door machine, when the laser detection fails, the output shaft of the synchronous cylinder 13 starts to extend outward and pushes the clamping block 12 to move forward, so that the clamping block 12 is clamped into the gap of the fixed block 9. In the process of moving the clamping block 12, the guide rod 14 will slide in the inside of the fixed frame 15, which plays a limiting role. The fixed block 9 will definitely be worn out after a long time of use. At this time, tools can be used to remove the fixed bolt 11 from the inside of the threaded hole 7. After removing the fixed bolt 11, the fixed block 9 can be pulled outward, and the mounting block 8 is pulled out from the inside of the mounting cavity 6 by the fixed block 9, and a new fixed block 9 is replaced. The mounting block 8 is partially inserted into the inside of the mounting cavity 6. At this time, the through hole 10 and the threaded hole 7 are in concentric state. When the fixed bolt 11 is installed in the threaded hole 7, the replacement of the fixed block 9 is completed. The above structure can prevent the hook 18 from being pushed up;

[0030] When the hook 18 is pushed up, the cable 17 will stretch the hook 18 to the bottom of the sliding plate 16. At this time, the bottom of the sliding plate 16 will be attached to the contact plate 27. With the continuous collection of the cable 17, the sliding rod 23 will slide in the inside of the limiting plate 24 and push the sliding block 22 downward. The sliding block 22 slides on the outside of the fixed rod 21 and pushes the fixed block 9 to make cross movement, so that the fixed rod 21 is clamped on both sides of the sliding plate 16. At this time, even if the cable 17 breaks during stretching, the hook 18 can also be prevented from falling off. During the rotation of the fixed rod 21, the plastic sheet 26 will be continuously compressed. The plastic sheet 26 will gradually break during compression. The plastic sheet 26 is used to support the fixed rod 21 to prevent the fixed rod 21 from closing too early. After confirming that there is no worker under the door machine, the hook 18 can be removed from the bottom of the sliding plate 16 by using tools, and a new plastic sheet 26 can be replaced for reuse.

[0031] The embodiments of the specific embodiment are the preferred embodiments of the utility model, which are not limited to the protection scope of the utility model, so that: any equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
