[0032] Referring to Figure 3 , the working process that the user disassembles towing frame 200 is: 1, drive push -out piece 300 to slide and push the convex part 411 in recess 421, make convex part 411 clockwise swing and move away from recess 421, and make first abutment 412 clockwise swing and remove abutment with abutment platform 422, 2, drive towing frame 200 to move relative to trailer body 100, make insertion block 420 pull off insertion slot 110 and complete the disassembly work of towing frame 200.

[0033] Through the above structure, the user only needs to drive push -out piece 300 to slide and drive towing frame 200 to move relative to trailer body 100 to complete the work of disassembling towing frame 200, so it can be known that the above-mentioned working process of the user to disassemble towing frame 200 is relatively simple, and the time required for the user to complete the work of disassembling towing frame 200 is relatively short.

[0034] In order to make the convex part 411 more smoothly swing and embed into the recessed position 421 in the process of inserting the insertion block 420 into the insertion slot 110, referring to Figure 2 and Figure 3 The insertion block 420 is provided with a guide slope 424, wherein the convex part 411 can move along the guide slope 424 to the recessed position 421 when the insertion block 420 is inserted into the insertion slot 110.

[0035] In this embodiment, referring to Figure 1 The rear end of the trailer body 100 is provided with two insertion slots 110, and the towing frame 200 is provided with two insertion blocks 420, which are inserted into the two insertion slots 110 one by one and respectively abut against the corresponding slot bottom wall 111.

[0036] In this embodiment, the front end of the trailer body 100 is also provided with two insertion slots 110, when the towing frame 200 is detached from the rear end of the trailer body 100, the user can drive the two insertion blocks 420 of the towing frame 200 to be inserted into the two insertion slots 110 at the front end one by one and respectively abut against the corresponding slot bottom wall 111, so as to install the towing frame 200 at the front end of the trailer body 100 to adapt to the actual transportation requirements.

[0037] The pushing piece 300 is slidably arranged in the towing frame 200, specifically, referring to Figures 2 to 4 The towing frame 200 is provided with a branch pipe 210, one end of the branch pipe 210 is provided with a through hole 211 communicating with the inner cavity thereof, the insertion block 420 is provided with a sleeving slot 423 communicating with the recessed position 421, the insertion block 420 is sleeved on one end of the branch pipe 210 through the sleeving slot 423, the pushing piece 300 is slidably arranged in the inner cavity of the branch pipe 210 and penetrates the through hole 211, the pushing piece 300 is provided with a pushing block 310 located outside the through hole 211, and the pushing block 310 can slide and push the convex part 411 located in the recessed position 421.

[0038] It can be understood that the pushing block 310 can slide and push the convex part 411 located in the recessed position 421, that is, the pushing block 310 can slide to the recessed position 421 to push the convex part 411.

[0039] Through the above structure, the pushing piece 300 is arranged in the inner cavity of the branch pipe 210, on the one hand, the pushing piece 300 can be compactly arranged in the towing frame 200, and on the other hand, the pushing piece 300 can be protected to a certain extent.

[0040] In order to facilitate the user to drive the pushing piece 300 to slide, referring to Figures 2 to 4The other end of the branch pipe 210 is rotationally connected with a pressing piece 430, the pressing piece 430 is provided with a third abutting portion 431 in the inner cavity of the branch pipe 210, the pressing piece 430 can be pressed by a user to make the third abutting portion 431 rotationally push the pushing piece 300 to slide, and make the pushing block 310 slide to push the convex portion 411 in the recess 421.
