[0026] The fixing mechanism 8 includes an installation cavity 801, an electromagnet 802, a second spring 803 and a clamping block 804. The installation cavity 801 is provided on the groove wall of the placement cavity 601. The electromagnet 802 is fixedly installed on the inner wall of the installation cavity 801. The second spring 803 is installed inside the installation cavity 801. A clamping block 804 is slidably installed on one side of the second spring 803. A mounting rod 701 is fixedly installed on the bottom of the pressure reducing plate 7. A clamping groove 702 is provided on the surface of the mounting rod 701. The size of the clamping groove 702 matches the size of the clamping block 804.

[0027] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the device is in use, the pressure relief plate 7 is installed inside the buffer seat 6, and the electromagnet 802 is energized by the external controller. After the electromagnet 802 is energized, suction is generated to suck the card block 804 into the inner cavity of the installation cavity 801, and then the installation rod 701 is placed in the inner cavity of the placement cavity 601, and the card slot 702 will correspond to the card block 804. At this time, the electromagnet 802 is de-energized by the external controller, and the card block 804 will pop outward under the elastic force of its internal spring 803, so that the pressure relief plate 7 can be fixedly installed inside the placement cavity 601, so that the pressure relief plate 7 can protect the surface of the placement groove 101 through the pressure relief plate 7 to prevent the surface of the placement groove 101 from being worn during long-term use and affecting the service life of the chain reel body 1.

[0029] Specifically, Figure 1 , Figure 2 As shown, when the output end of the hoist body 3 drives the mounting block 2 to rotate to reel in the chain, the chain will squeeze the pressure relief plate 7 inside the placement groove 101, and the buffer seat 6 below the pressure relief plate 7 will slide in the inner cavity of the mounting groove 4, thereby being able to buffer the impact force of the chain on the chain reel body 1 through the spring 1 502 on the outside of the damper 501, and cooperating with the elasticity of the spring 3 9 under the pressure relief plate 7, thereby being able to reduce the pressure on the impact force on the chain reel body 1, and at the same time being able to protect the chain reel body 1, thereby being able to improve the service life of the chain reel body 1 to a certain extent.

[0030] Working principle: when the pressure relief plate 7 is installed inside the buffer seat 6, the electromagnet 802 is energized through the external controller, and the electromagnet 802 generates suction after being energized to suck the card block 804 into the inner cavity of the installation cavity 801, and then the installation rod 701 is placed into the inner cavity of the placement cavity 601, and the card slot 702 will correspond to the card block 804. At this time, the electromagnet 802 is de-energized through the external controller, and the card block 804 will pop outward under the elastic force of the internal spring 803, so that the pressure relief plate 7 can be fixedly installed inside the placement cavity 601, so that it can be The pressure reducing plate 7 protects the surface of the placement groove 101. When the output end of the hoist body 3 drives the mounting block 2 to rotate to reel in the chain, the chain will squeeze the pressure reducing plate 7 inside the placement groove 101, and the buffer seat 6 under the pressure reducing plate 7 will slide in the inner cavity of the mounting groove 4, thereby being able to buffer the impact force of the chain on the chain reel body 1 through the spring 1 502 on the outside of the damper 501, and cooperating with the elasticity of the spring 3 9 under the pressure reducing plate 7, thereby being able to reduce the pressure on the impact force on the chain reel body 1 and protect the chain reel body 1 at the same time.

[0031] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it.
