By arranging the tow rope body 14, one end of the tow rope body 14 is fixedly arranged at one end of the roller shaft 11, so as to avoid the roller shaft 11 from rotating excessively and causing the tow rope body 14 to fall off the roller shaft 11, and to avoid the tow rope body 14 from being separated from the outer surface of the roller shaft 11 during towing, which affects the use, and the excess tow rope body 14 is wound around the outer surface through the rotation of the roller shaft 11, one end of the roller shaft 11 passes through one side of the mounting frame 1, and a motor 2 is arranged on one side of the mounting frame 1, and the roller shaft 11 passes through one side of the mounting frame 1. The end is fixedly installed on the driving end of the motor 2, and a reciprocating screw 3 is rotatably installed in the middle of the side of the mounting frame 1 away from the roller shaft 11, one end of the reciprocating screw 3 passes through the mounting frame 1, and a connecting component is provided on the side of the reciprocating screw 3 passing through the mounting frame 1, and a sliding block 31 that cooperates with each other is installed on the outer surface of the reciprocating screw 3, a first fixed block 32 is fixedly installed on one side of the top of the sliding block 31, a first limiting roller 33 is fixedly installed on the lower part of one side of the first fixed block 32, a second fixed block 35 is fixedly installed on the top of the sliding block 31 away from the first fixed block 32, the other side of the first limiting roller 33 is fixedly installed on the lower part of the second fixed block 35, and a second limiting roller 34 is provided on the top of the first limiting roller 33.

[0017] A first slider 341 is rotatably mounted on one side of the second limiting roller 34, and a second slider 342 is fixedly mounted on the side of the second limiting roller 34 away from the first slider 341. A first screw 36 is threadedly mounted on the upper part of the first fixed block 32, and the upper part of the first screw 36 passes through the first fixed block 32. The bottom end of the first screw 36 is rotatably mounted on the middle part of the top end of the first slider 341. A second screw 37 is threadedly mounted on the upper part of the second fixed block 35, and the upper part of the second screw 37 passes through the second fixed block 35.

[0018] A fixing plate 13 is fixedly mounted on one side of the mounting frame 1 , and the bottom end of the motor 2 is fixedly mounted on the top end of the fixing plate 13 . By providing the fixing plate 13 , the fixing plate 13 is used to fix the motor 2 .

[0019] The connecting component includes a driving wheel 21, the middle part of which is fixedly installed on the middle part of the driving end of the motor 2, and the reciprocating screw rod 3 passes through one end of the mounting frame 1 and is fixedly installed with a driven wheel 22. The middle parts of the driving wheel 21 and the driven wheel 22 are sleeved with a belt 23 that cooperates with each other. By setting the driving wheel 21, the belt 23 and the driven wheel 22, under the drive of the motor 2, through the mutual cooperation of the driving wheel 21, the belt 23 and the driven wheel 22, the reciprocating screw rod 3 can be driven to rotate, and under the mutual cooperation with the sliding block 31, the tow rope body 14 is driven to reciprocate, so that it is evenly wound around the outer surface of the roller 11.

[0020] The middle part of the second slider 342 is provided with a limiting hole 343, and the lower part of the second screw rod 37 is slidably clamped in the middle part of the limiting hole 343. By setting the limiting hole 343, when the towing rope body 14 moves between the first limiting roller 33 and the second limiting roller 34, the second screw rod 37 is away from the limiting hole 343 to avoid affecting the rotation of the second slider 342 in the second slide groove 351 and affecting the normal pulling out of the towing rope body 14. When the towing rope body 14 is used to tow the car, the rotation When the second limiting roller 34 is moved so that the limiting hole 343 is located below the second screw 37, the second screw 37 is rotated so that the lower part of the second screw 37 is inserted into the limiting hole 343, that is, the second limiting roller 34 is limited and does not rotate, and the first screw 36 is rotated so that the second limiting roller 34 contacts the outer surface of the towing rope body 14 for clamping, that is, the force generated by the clamping friction is used to reduce the force on the roller shaft 11 during towing, thereby increasing the service life of the entire structure.

[0021] A first slide groove 321 is provided in the middle of one side of the first fixed block 32, and the first slider 341 is slidably clamped inside the first slide groove 321. By setting the first slide groove 321, the first slider 341 is driven to move up and down inside the first slide groove 321 under the rotation of the first screw rod 36, thereby driving the first limiting roller 33 to move up and down more stably.

[0022] A second slide groove 351 is provided in the middle of one side of the second fixed block 35, and the second slider 342 is slidably clamped in the second slide groove 351. By setting the second slide groove 351, the second slider 342 installed on one side of the second limiting roller 34 is limited by the second slide groove 351, so that the second limiting roller 34 is more stable when moving up and down.

[0023] A limiting rod 12 is fixedly installed on the lower part of one side of the mounting frame 1, and the lower part of the sliding block 31 is slidably clamped on the outer surface of the limiting rod 12. By setting the limiting rod 12, when the reciprocating screw rod 3 rotates, the limiting rod 12 limits the sliding block 31, so that the sliding block 31 can drive the sliding block 31 to reciprocate in cooperation with the reciprocating screw rod 3, that is, drive the tow rope body 14 to reciprocate, so that the tow rope body 14 is evenly wound around the outer surface of the roller shaft 11.

[0024] Working principle: When in actual use, the mounting frame 1 is mounted on the rear of the trailer, and the trailer rope body 14 is pulled out by pulling the trailer rope body 14 in cooperation with the motor 2. When the appropriate length is reached, the motor 2 is stopped to control the length of the trailer rope body 14, and one end of the trailer rope body 14 is mounted on the front end of the vehicle that needs to be towed for use. When not in use, the motor 2 is started to reverse and the roller 11 is driven to rotate, that is, the trailer rope body 14 is wound so that it is wrapped around the outer surface of the roller 11. At the same time, the reciprocating screw rod 3 is driven to rotate under the cooperation of the driving wheel 21, the driven wheel 22 and the belt 23, that is, the sliding block 31 is driven to move back and forth, thereby driving the trailer rope body 14 running through the first limiting roller 33 and the second limiting roller 34 to move back and forth left and right, so that the trailer rope body 14 is evenly wound around the outer surface of the roller 11;

[0025] By rotating the first screw 36, the distance between the second limiting roller 34 and the first limiting roller 33 can be adjusted, so as to facilitate the limiting of towing rope bodies 14 of different thicknesses. When the towing rope body 14 is pulled out or wound, the second screw 37 is located at the upper part of the second fixing block 35, so that it is away from the second limiting hole 343, that is, it will not affect the rotation of the second limiting roller 34. When the towing rope body 14 is used to tow the vehicle, by rotating the second limiting roller 34, the limiting hole 343 is located below the second screw 37, and by rotating the second screw 37, the lower part of the second screw 37 is inserted into the inside of the limiting hole 343, that is, the second limiting roller 34 is limited and will not rotate. By rotating the first screw 36, the second limiting roller 34 is in contact with the outer surface of the towing rope body 14 for clamping, that is, the force generated by the clamping friction is used to reduce the force on the roller shaft 11 during towing, so as to increase the service life of the overall structure.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
