The bottom surface of the bottom plate 225 is slidably installed inside the second connection groove 227, and the bottom plate 225 can limit the position of the connecting piece 221 through the second connection groove 227. The top surface of the fixing plate 226 is movably installed inside the clamping groove 2211, and the fixing plate 226 can improve the stability of the bottom plate 225 through the clamping groove 2211. The front end of the adjusting screw 224 threadedly penetrates through the fixing box 223 and extends to the front side of the fixing box 223. The rear side of the plug plate 229 movably penetrates through the inside of the fixing box 223, the front sides of the second fixing frame 222 and the bottom plate 225 and extends to the inside of the slot 2210, and rotating the adjusting screw 224 can drive the movable plate 228 to move backward to insert the plug plate 229 into the slot 2210 to fix the connecting piece 221.

[0029] The replacement of the connecting member 221 is facilitated by the provided bottom plate 225 and insertion plate 229. When it is necessary to meet the requirements of a static working environment, the rotary adjusting screw 224 is rotated to drive the movable plate 228 to extract the insertion plate 229 from the inside of the slot 2210 and the bottom plate 225. Then, the connecting member 221 can be slid to drive the bottom plate 225 to be pulled out from the inside of the second connecting groove 227. Then, it is replaced with a fixed hook and the bottom plate 225 is inserted into the inside of the second connecting groove 227.

Then, the adjusting screw 224 is rotated in the reverse direction to drive the movable plate 228 to insert the insertion plate 229 through the bottom plate 225 into the inside of the slot 2210 to fix the fixed hook, which is convenient for disassembly and replacement and has good practicability.

[0030] The second implementation manner is mainly different from the first implementation manner in that: the limiting component 21 includes first fixing frames 211 fixedly installed on the left and right sides of the mounting frame of the electric hoist body 1. A positive and negative screw 212 is movably installed inside the first fixing frame 211. A DC motor 213 is fixedly installed on the front side of the first fixing frame 211. First connecting grooves 214 are opened on the left and right sides of the mounting frame of the electric hoist body 1. Movable rings 217 are threadedly installed at the front and rear ends of the positive and negative screw 212. Limiting plates 215 are fixedly installed on the opposite sides of the movable rings 217. Brake blocks 216 are fixedly installed on the opposite sides of the limiting plates 215.

[0033] During use, the user installs the device on the slide rail through the connecting member 221, then starts the DC motor 213 to drive the forward and reverse screw rod 212 to rotate, so that the movable ring 217 moves towards the opposite side. Then, the movable ring 217 will make the brake block 216 move towards the opposite side through the limiting plate 215. When it moves to the appropriate position, the DC motor 213 is turned off to fix the position of the limiting plate 215. At this time, the electric hoist body 1 is started for hoisting, and the limiting plate 215 can limit the rope of the electric hoist body 1 to avoid large swings. When the electric hoist body 1 stops lifting and lowering the rope to fix the hoisted object, the electric hoist body 1 will fix the rope, and at the same time, the DC motor 213 will be started to drive the forward and reverse screw rod 212 to rotate, so that the movable ring 217 moves towards the opposite side. Then, the movable ring 217 will drive the limiting plate 215 to clamp and fix the rope through the brake block 216, improving the stability of the device. When it is necessary to meet the requirements of a static working environment, the adjusting screw rod 224 is rotated to drive the movable plate 228 to pull out the plug plate 229 from the inside of the slot 2210 and the bottom plate 225. Then, the connecting member 221 can be slid to pull out the bottom plate 225 from the inside of the second connecting groove 227, and then it is replaced with a fixed hook to insert the bottom plate 225 into the inside of the second connecting groove 227. At the same time, the fixing plate 226 will be located inside the card slot 2211.
