A groove 13 is provided at the bottom of the base 1 to reduce the overall weight and manufacturing cost of the device.

[0027] The mounting mechanism includes a first support shaft 21 rotatably connected to the first support plate 11 and a sleeve 22 fixedly connected to the second support plate 12. The first support shaft 21 and the sleeve 22 pass through the first support plate 11 and the second support plate 12 respectively. The first support shaft 21 is fixedly connected to the motor 23 at one end outside the first support plate 11. The sleeve 22 is rotatably connected to the second support shaft 24 through a bearing. An annular groove is provided on the side wall of the sleeve 22, and the bearing is slidably connected in the annular groove, so that the second support shaft 24 and the sleeve 22 can rotate or slide relative to each other. The second support shaft 24 is in the sleeve 2 2 is fixedly connected to a limit plate 241, and the limit plate 241 is slidably connected to the inner wall of the sleeve 22. A spring 242 is sleeved on the second support shaft 24 between the side wall of the limit plate 241 away from the cable reel 25 and the side wall of the sleeve 22. The cable reel 25 is clamped between the first support shaft 21 and the second support shaft 24. The ends of the first support shaft 21 and the second support shaft 24 close to each other are fixedly connected to a clamping block 27. A clamping slot adapted to the clamping block 27 is provided on the cable reel 25. The clamping method facilitates installation and disassembly and improves work efficiency. The end of the second support shaft 24 away from the cable reel 25 is fixedly connected to a handle 26.

[0028] The traction mechanism includes two symmetrically arranged mounting plates 31 fixedly connected to the upper surface of the base 1, and two sliders 32 are slidingly connected on the side walls of the mounting plates 31 that are close to each other. A bidirectional screw 33 is threadedly connected between the two sliders 32 on the same mounting plate 31, and the bottom end of the bidirectional screw 33 passes through the base 1 and is rotatably connected to the base 1. The bottom ends of the two bidirectional screws 33 are fixedly connected to pulleys 34, and the two pulleys 34 are connected by belts 35.

[0029] The functional principle of the present invention can be explained through the following operation mode: when in use, the hand wheel 331 is rotated, and the hand wheel 331 drives the bidirectional screw 33 to rotate. Under the action of the belt 35 and the pulley 34, the two bidirectional screws 33 rotate synchronously. The two sliders on the same bidirectional screw 33 move away from each other, driving the central axis 36 and the threading wheel 37 to move away from each other. The cable on the cable reel 25 is passed through the middle of the two threading wheels. The hand wheel 331 is rotated in the opposite direction to make the two threading wheels 37 move closer to each other to fix the cable. It is suitable for cables of different thicknesses and has a wide range of applications. Then, the motor 2 is turned on. 3 starts to pay out the cable. When the cable on the cable reel 25 is threaded, the handle 26 is pulled, and the second support shaft 24 moves in the direction away from the cable reel 25. The clamping block 27 on the second support shaft 24 is separated from the clamping slot on the cable reel 25. The spring 242 is in a compressed state. At this time, the cable reel 25 is replaced. After the replacement is completed, the handle 26 is released. Under the action of the spring 242, the limit plate 241 drives the second support shaft 24 to move in the direction close to the cable reel 25. The clamping block 27 is clamped in the clamping slot on the cable reel 25 to complete the replacement. The operation is convenient and the work efficiency is high.
