Through the sliding of the racks 207, it is convenient to drive the movement of the limiting arm 202, thereby facilitating the clamping and fixing of the article by the limiting arm 202.
[0043] In addition, a second sliding groove matching the rack 207 is formed in the fixing frame 201. Through the formation of the second sliding groove, it is convenient for the rack 207 to slide, thereby ensuring the stability of the sliding of the rack 207.
[0044] As Figures 2 to 5 shown, the limiting arm 202 is fixedly installed on the rack 207. A plurality of pairs of electric telescopic rods 208 are fixedly installed in the fixing frame 201. The electric telescopic rods 208 are connected to the toothed plate 203. This model is SC32, which has the function of telescoping and is convenient for controlling the movement of the toothed plate 203.
[0045] As Figures 2 to 5 shown, an anti-detachment mechanism 3 is installed on the lower side of the lifting head body 101. The anti-detachment mechanism 3 includes a connecting frame 301. The connecting frame 301 is connected to the lifting head body 101, which plays a supporting role. Through the support of the connecting frame 301, it is convenient to install corresponding mechanisms on the connecting frame 301, so as to restrict the binding rope of the article.
[0046] As Figures 2 to 5 shown, a hook bin 302 is fixedly installed on the connecting frame 301, which is convenient for hanging the article, and at the same time facilitates the setting function of the internal hook bin 302.
[0047] In addition, a toothed ring 303 is provided in the hook compartment 302, which has the function of moving according to the shape of the hook compartment 302, so as to facilitate the advantage of surrounding the place where the item is hung, and prevent the place where the item is hung from slipping.

[0052] In specific use, in order to reduce the shaking of the objects when being hoisted, first the objects to be hoisted need to be tied up and hung on the hook bin 302, and then the motor 305 is used to drive the third gear 304 to rotate, and the rotation of the third gear 304 will drive the movement of the toothed ring 303 in the hook bin 302, so that the toothed ring 303 will surround according to the shape of the hook bin 302, thereby restricting the hanging rope of the tied objects to prevent the objects from being separated from the hook bin 302 when the lifting arm body 1 moves, and then the electric telescopic rod 208 can be used to simultaneously The contraction drives the tooth plate 203 to rise, and the tooth plate 203 drives the second gears 206 on both sides to rotate according to the rise of the first slide slot, so that the second gear 206 can drive the rotation of the rotating rod 204, and the rotation of the rotating rod 204 drives the rotation of the first gear 205. When the first gear 205 rotates, it can drive the rack 207 to move toward the middle, so that multiple pairs of limit arms 202 can clamp and fix the objects hoisted on the hook bin 302, so as to prevent the objects from shaking and falling off during the hoisting and moving process of the lifting arm body 1.
