[0003] However, existing towing belts are often fixed in length and cannot be flexibly adjusted to the actual obstacle location and clearing requirements. This means that when faced with obstacles at different distances or locations, operators must frequently remove and replace towing belts of varying lengths to ensure effective and safe clearing. This significantly increases operational complexity, prolongs work time, and reduces efficiency. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0022] Combine Figures 1-4 A towing device for a tow truck and leveler includes a towing body 1. A connecting box 2 is provided on the outer surface of the towing body 1. A cavity 22 is provided inside the connecting box 2. A connecting groove 23 is provided on the outer surface of the connecting box 2. The connecting groove 23 is communicated with the cavity 22. An adjusting component 4 for adjusting the length of the towing body 1 is provided inside the connecting box 2.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1:

[0025] See also Figure 1-Figure 5The adjusting assembly 4 includes a rotating shaft 41 rotatably connected to the bottom end of the inner wall of the cavity 22, a connecting plate 42 fixedly connected to the top of the rotating shaft 41, a telescopic rod 43 fixedly connected to the top of the connecting plate 42, a connecting block 44 fixedly connected to the telescopic end of the telescopic rod 43, a spring 45 fixedly connected between the connecting block 44 and the connecting plate 42, a connecting column 46 fixedly connected to the top of the connecting block 44, a connecting rod 47 fixedly connected to the outer surface of the connecting column 46, and a limiting column 48 fixedly connected to the bottom end of the connecting rod 47. A circular groove 24 and a limiting groove 21 are provided at the top of the connecting box 2. The circular groove 24 is connected to the cavity 22. The connecting block 44 is correspondingly arranged with the circular groove 24. The limiting column 48 is correspondingly arranged with the limiting groove 21. There are multiple groups of limiting grooves 21. A through hole 421 is provided on the outer surface of the connecting plate 42. The spring 45 is provided on the outside of the telescopic rod 43. On the other side, the towing body 1 passes through the connecting groove 23 and the through-hole 421, pulling the connecting post 46, which moves upward to drive the connecting block 44 away from the circular groove 24. At this time, the telescopic rod 43 and the spring 45 are both in a stretched state, and the connecting post 46 is rotated, thereby driving the connecting plate 42 to rotate. Under the action of the through-hole 421, it is convenient to wrap the towing body 1 around the outer surface of the connecting plate 42, thereby facilitating the shortening of the length of the towing body 1. After the adjustment is completed, the connecting block 44 is driven close to the circular groove 24 under the reaction of the spring 45, thereby driving the limiting post 48 close to the limiting groove 21. When the limiting post 48 is engaged with the limiting groove 21, it is convenient to fix the limiting post 48, thereby fixing the connecting plate 42 to prevent the towing body 1 from loosening. Through multiple sets of limiting grooves 21, it is convenient to adjust the towing body 1 to different lengths, and it can be firmly fixed after each adjustment.

[0026] The bottom ends of the inner walls of the multiple groups of limiting grooves 21 are fixedly connected to first magnetic blocks 211, and the bottom ends of the limiting posts 48 are fixedly connected to second magnetic blocks 481. The first magnetic blocks 211 and the second magnetic blocks 481 have opposite magnetic poles. When the limiting posts 48 are engaged with the limiting grooves 21, an attractive force is generated between the first magnetic blocks 211 and the second magnetic blocks 481, thereby enhancing the fixing effect between the limiting posts 48 and the limiting grooves 21. At the same time, during operation, the magnetic attraction provides clear feedback to the operator. When the sound or vibration of the first magnetic blocks 211 and the second magnetic blocks 481 are heard or felt, it is confirmed that they are properly fixed.

[0027] The top of the connecting column 46 is fixedly connected to a manual crank 6, and the outer surface of the manual crank 6 is provided with anti-skid patterns. The anti-skid patterns are convenient for increasing the friction coefficient of the outer surface of the manual crank 6, making the operator more stable when turning the manual crank 6 and not easy to slip.

[0028] A mounting plate 5 is provided on the sidewall of the connecting groove 23. A cleaning brush 51 is provided on the side of the mounting plate 5 away from the sidewall of the connecting groove 23. The cleaning brush 51 contacts the outer surface of the towing body 1. As the towing body 1 moves along the connecting groove 23, the cleaning brush 51 continuously contacts the outer surface of the towing body 1, effectively removing dust, dirt, and other dirt from the outer surface of the towing body 1, thereby keeping the outer surface of the towing body 1 clean.

[0029] A first loop belt 3 is provided at one end of the towing body 1, and a second loop belt 7 is provided at the other end of the towing body 1. A first fixing buckle 9 is provided between the first loop belt 3 and the towing body 1, and a second fixing buckle 8 is provided between the second loop belt 7 and the towing body 1. The first loop belt 3 and the second loop belt 7 are connected to external hooks or other connecting parts. The first loop belt 3 is fixed to the towing body 1 through the first fixing buckle 9, and the second loop belt 7 is fixed to the towing body 1 through the second fixing buckle 8.

[0030] The outer surfaces of the first fixing buckle 9 and the second fixing buckle 8 are both provided with sewn ropes, which pass through the first loop belt 3, the second loop belt 7, and the towing body 1. The sewn ropes pass through the first loop belt 3, the second loop belt 7, and the towing body 1 to form a multiple fixing structure, making the connection between the various components more secure and improving the connection strength.

[0031] When in use, pull the connecting post 46, the connecting post 46 moves upward and drives the connecting block 44 away from the circular groove 24. At this time, the telescopic rod 43 and the spring 45 are both in a stretched state. The connecting post 46 is rotated by the manual shaking plate 6, thereby driving the connecting plate 42 to rotate. Under the action of the through hole 421, it is convenient to wrap the towing body 1 around the outer surface of the connecting plate 42, thereby facilitating the shortening of the towing body 1. After the adjustment is completed, the reaction of the spring 45 drives the connecting block 44 close to the circular groove 24, thereby driving the limiting post 48 close to the limiting groove 21. When the limiting post 48 is in contact with the limiting groove 21, the limiting post 48 is in contact with the limiting groove 21. When the limiting grooves 21 are engaged and connected, an attractive force is generated between the first magnetic block 211 and the second magnetic block 481, thereby enhancing the fixing effect between the limiting column 48 and the limiting grooves 21, thereby facilitating the fixing of the connecting plate 42 and preventing the towing body 1 from loosening. The towing body 1 can be easily adjusted to different lengths through multiple sets of limiting grooves 21, and can be firmly fixed after each adjustment. During the adjustment process, the towing body 1 moves along the connecting grooves 23. At this time, the cleaning brush 51 is in constant contact with the outer surface of the towing body 1, which is convenient for effectively removing impurities on the outer surface of the towing body 1.
