There is at least one first pin hole 11 and at least one second pin hole 12. The number of the first pin holes 11 is determined according to the number of the first plug pins 31, and usually the number of the first pin holes 11 is the same as the number of the first plug pins 31. The number of the second pin holes 12 is determined according to the number of the second plug pins 32, and usually the number of the second pin holes 12 is the same as the number of the second plug pins 32. The second tube body 2 is provided with a third pin hole 21 and a fourth pin hole 22 on both sides, and there is at least one third pin hole 21 and at least one fourth pin hole 22. The third pin hole 21 corresponds to the position of the first pin hole 11. When there are multiple third pin holes 21, a certain third pin hole 21 is aligned with the first pin hole 11, and the first plug 31 is inserted into the first pin hole 11 and the third pin hole 21. The first plug 31 is inserted into different third pin holes 21. The position of the second tube body 2 in the first tube body 1 is different, and the length of the towing structure is different. The fourth pin hole 22 corresponds to the position of the second pin hole 12. When there are multiple fourth pin holes 22, a certain fourth pin hole 22 is aligned with the second pin hole 12, and the second plug 32 is inserted into the second pin hole 12 and the fourth pin hole 22.

The first tube body 1 is usually fixedly connected to the rear of the vehicle, and the second tube body 2 is connected to the front of the other vehicle.

[0068] Since the present application adopts the clamping assembly 4 to connect the first latch 31 and the second latch 32, the clamping assembly 4 can clamp and open, and drive the first latch 31 to move closer to and away from each other, that is, the first latch 31 can be inserted into the third pin hole 21, or the first latch 31 can be pulled out of the third pin hole 21, and the second latch 32 can be inserted into the fourth pin hole 22, or the second latch 32 can be pulled out of the fourth pin hole 22, thereby making the insertion and removal of the first latch 31 and the second latch 32 easier and more convenient.

[0069] In addition, when the clamping assembly 4 is opened, the first latch 31 can still be inserted into the first pin hole 11 or pulled out from the first pin hole 11 , and the second latch 32 can still be inserted into the second pin hole 12 or pulled out from the second pin hole 12 .

[0070] In one implementation of the embodiment of the present application, Figure 5 , Figure 6 , Fig.10 as well as Fig.11 As shown, the clamping assembly 4 includes: a first sliding member 41, a second sliding member 42 and an elastic member 43. The first sliding member 41 is connected to the first latch 31; the second sliding member 42 is connected to the second latch 32; the elastic member 43 is located between the first sliding member 41 and the second sliding member 42; the first sliding member 41 and the second sliding member 42 both slide relative to the first tube body 1; the elastic force provided by the elastic member 43 makes the first latch 31 and the second latch 32 move closer to each other.

[0071] Specifically, the sliding member refers to a component that slides relative to the first tube body 1. The sliding directions of the first sliding member 41 and the second sliding member 42 are opposite. When the first sliding member 41 drives the first latch 31 to slide toward the second latch 32, the first latch 31 is inserted into the first pin hole 11 and the third pin hole 21; when the first sliding member 41 drives the first latch 31 to slide away from the second latch 32, the first latch 31 is pulled out of the third pin hole 21. When the second sliding member 42 drives the second latch 32 to slide toward the first latch 31, the second latch 32 is inserted into the second pin hole 12 and the fourth pin hole 22; when the second sliding member 42 drives the second latch 32 to slide away from the first latch 31, the second latch 32 is pulled out of the fourth pin hole 22. The elastic force provided by the elastic member 43 pushes the first sliding member 41 and the second sliding member 42 to slide, and the first latch 31 and the second latch 32 are moved closer to each other. When pressure is applied to the first sliding member 41 and the second sliding member 42 to overcome the elastic force of the elastic member 43, the first latch 31 and the second latch 32 move away from each other, and the first latch 31 is pulled out of the third pin hole 21, and the second latch 32 is pulled out of the fourth pin hole 22. The elastic member 43 can be a spring, and the number of the elastic members 43 can be set as needed.

[0072] In one implementation of the embodiment of the present application, Figure 6 , Fig. 9 as well as Fig.10 As shown, the first sliding member 41 includes: a first connecting portion 411, a first abutting portion 412 and a first transverse portion 413. The first connecting portion 411 is connected to the first latch 31; the first abutting portion 412 abuts against the first end of the elastic member 43; the two ends of the first transverse portion 413 are respectively connected to the first connecting portion 411 and the first abutting portion 412; the first connecting portion 411 and the first abutting portion 412 are respectively located on both sides of the elastic member 43.

[0073] Specifically, the first connecting portion 411 is used to connect the first latch 31, the first abutting portion 412 is used to abut against the elastic member 43, the first transverse portion 413 spans the first tube body 1 and connects the first connecting portion 411 and the first abutting portion 412, and the first connecting portion 411, the first transverse portion 413 and the first abutting portion 412 are sequentially connected to form a Z-shaped member. The first connecting portion 411 and the first abutting portion 412 are respectively located on both sides of the elastic member 43.

[0074] In one implementation of the embodiment of the present application, Figure 5 , Figure 8 as well as Fig.10 As shown, the second sliding member 42 includes: a second connecting portion 421, a second abutting portion 422 and a second transverse portion 423. The second connecting portion 421 is connected to the second latch 32; the second abutting portion 422 abuts against the second end of the elastic member 43; the two ends of the second transverse portion 423 are respectively connected to the second connecting portion 421 and the second abutting portion 422; the second connecting portion 421 and the second abutting portion 422 are respectively located on both sides of the elastic member 43.

[0075] Specifically, the second connecting portion 421 is used to connect the second latch 32, the second abutting portion 422 is used to abut against the elastic member 43, the second transverse portion 423 spans the first tube body 1 and connects the second connecting portion 421 and the second abutting portion 422, and the second connecting portion 421, the second transverse portion 423 and the second abutting portion 422 are sequentially connected to form a Z-shaped member. The second connecting portion 421 and the second abutting portion 422 are respectively located on both sides of the elastic member 43.

[0076] The first sliding member 41 forms a Z shape, and the second sliding member 42 also forms a Z shape, and the Z shape of the first sliding member 41 and the Z shape of the second sliding member 42 are symmetrical to each other. When the first connecting portion 411 and the second connecting portion 421 are brought close to each other, the first abutting portion 412 and the second abutting portion 422 are separated from each other, and the first latch 31 and the second latch 32 are brought close to each other. When the first connecting portion 411 and the second connecting portion 421 are separated from each other, the first abutting portion 412 and the second abutting portion 422 are brought close to each other, and the first latch 31 and the second latch 32 are separated from each other. Since the elastic member 43 is located between the first abutting portion 412 and the second abutting portion 422, when the first abutting portion 412 and the second abutting portion 422 are brought close to each other and compress the elastic member 43, the first latch 31 and the second latch 32 can be separated from each other to achieve unlocking. When the elastic member 43 recovers its deformation, the first abutting portion 412 and the second abutting portion 422 are pushed away, so that the first latch 31 and the second latch 32 are brought close to each other to achieve locking.

[0077] In one implementation of the embodiment of the present application, Figure 5 , Figure 6 , Fig.10 as well as Fig.11 As shown, a first gripping portion 414 is disposed on the first abutting portion 412 , and a second gripping portion 424 is disposed on the second abutting portion 422 .

[0078] Specifically, the hand-held portion refers to a part for the user's hand or hand to hold. In order to conveniently control the first abutting portion 412 and the second abutting portion 422 to move closer to each other, a first hand-held portion 414 is provided on the first abutting portion 412, and a second hand-held portion 424 is provided on the second abutting portion 422. When the first hand-held portion 414 and the second hand-held portion 424 are pinched, the first abutting portion 412 and the second abutting portion 422 can be easily moved closer.

[0079] In one implementation of the embodiment of the present application, Figure 10-11 As shown, when the first hand-held portion 414 and the second hand-held portion 424 abut against each other, the first latch pin 31 is disengaged from the third pin hole 21 , and the second latch pin 32 is disengaged from the fourth pin hole 22 .

[0080] Specifically, the first hand-held portion 414 and the second hand-held portion 424 are spaced apart, the distance between the first hand-held portion 414 and the second hand-held portion 424 is greater than twice the thickness of the second tube body 2, the moving distance of the first hand-held portion 414 is equal to the moving distance of the first latch 31, the moving distance of the second hand-held portion 424 is equal to the moving distance of the second latch 32, and the moving distance when the first hand-held portion 414 and the second hand-held portion 424 are brought close to each other is sufficient to pull the first latch 31 out of the third pin hole 21, and sufficient to pull the second latch 32 out of the fourth pin hole 22.

[0081] In one implementation of the embodiment of the present application, Figure 2 and Fig.11 As shown, the first transverse portion 413 and the second transverse portion 423 are both against the first tube body 1 .

[0082] Specifically, the first transverse portion 413 and the second transverse portion 423 may abut against the first tube body 1 and slide on the first tube body 1 , and the first tube body 1 may support the first transverse portion 413 and the second transverse portion 423 .

[0083] In one implementation of the embodiment of the present application, Figure 5 , Figure 6 as well as Fig.10 As shown, there are two second transverse portions 423 , and the first transverse portion 413 is located between the two second transverse portions 423 ; or there are two first transverse portions 413 , and the second transverse portion 423 is located between the two first transverse portions 413 .

[0084] Specifically, there are two second transverse parts 423, and both ends of each second transverse part 423 are connected to the second connecting part 421 and the second abutting part 422. A gap is formed between the two second transverse parts 423, and the first transverse part 413 is located in the gap. The two second transverse parts 423 limit the sliding of the first transverse part 413, and limit the movement of the first transverse part 413 in the length direction of the first tube body 1. It is also possible to use two first transverse parts 413 and one second transverse part 423, and the second transverse part 423 is located between the two first transverse parts 413, and the two first transverse parts 413 guide the sliding of the second transverse part 423.

[0085] In one implementation of the embodiment of the present application, Figure 5-Figure 10 As shown, both the first abutting portion 412 and the second abutting portion 422 are provided with shaft holes 44 , and the clamping assembly 4 further includes: a guide shaft 45 ; the guide shaft 45 passes through the two shaft holes 44 in sequence.

[0086] Specifically, in order to further guide the sliding of the first sliding member 41 and the sliding of the second sliding member 42, shaft holes 44 are provided on the first abutting portion 412 and the second abutting portion 422, and both ends of the guide shaft 45 pass through the shaft holes 44 respectively. Under the guiding action of the guide shaft 45, the first sliding member 41 and the second sliding member 42 are not easy to move in the length direction of the first tube body 1. When the elastic member 43 is a spring, the guide shaft 45 can be inserted into the spring to guide the compression deformation of the spring, and the spring is not easy to bend in the length direction of the first tube body 1.

[0087] In one implementation of the embodiment of the present application, Figure 7-Figure 11 As shown, blocking portions 451 are provided at both ends of the guide shaft 45 , and the blocking portions 451 cannot pass through the shaft hole 44 .

[0088] Specifically, the blocking portion 451 is used to block the first sliding member 41 and the second sliding member 42 to limit the sliding range of the first sliding member 41 and the sliding range of the second sliding member 42. There are two blocking portions 451, one blocking portion 451 is fixedly provided with the guide shaft 45, and the other blocking portion 451 is detachably provided on the guide shaft 45. For example, a bolt and a nut can be used as the guide shaft 45 provided with the blocking portion 451.

[0089] In one implementation of the embodiment of the present application, Figure 3-Figure 4 As shown, the number of the third pin holes 21 is greater than the number of the first plug pins 31 , and the number of the fourth pin holes 22 is greater than the number of the second plug pins 32 .

[0090] Specifically, the number of third pin holes 21 can be greater than the number of first pin holes 11, and the number of fourth pin holes 22 can be greater than the number of second pin holes 12. Then the first pin hole 11 can be aligned with different third pin holes 21, and the second pin hole 12 can be aligned with different fourth pin holes 22, so the second tube body 2 is located at different positions in the first tube body 1.

[0091] In one implementation of the embodiment of the present application, Figure 1 and Figure 2 As shown, a connecting ball head 6 is provided on the second tube body 2 .

[0093] In one implementation of the embodiment of the present application, Figure 1 , Figure 2 as well as Figure 4 As shown, the height of the connecting ball head 6 is lower than the height of the first tube body 1 .

[0094] Specifically, the height of the connecting ball head 6 is lower than the height of the first tube body 1. Usually, the height of the rear of the vehicle is higher, while the height of the front is lower. The first tube body 1 is connected to the rear of the vehicle, and the connecting ball head 6 is connected to the front of another vehicle. When the height of the connecting ball head 6 is configured to be at a lower position, it is convenient to connect the connecting ball head 6 to another vehicle. The connecting ball head 6 is connected to the second tube body 2 through a mounting plate 61. The mounting plate 61 is V-shaped. The two sides of the V-shaped mounting plate 61 are respectively connected to the second tube body 2 and the connecting ball head 6. An obtuse angle is formed between the two sides of the V-shaped mounting plate 61. The connecting ball head 6 can be bolted to one side of the V-shaped mounting plate 61, or welded to one side of the V-shaped mounting plate 61. The other side of the V-shaped mounting plate 61 is welded to the second tube body 2.
