[0032] Specifically, the towing bracket 12 consists of a bottom connecting plate 1, a side plate 2, a first slider bracket 3, a second slider bracket 13 and a protective cover mounting plate 14, wherein the side plate 2 is welded to the bottom connecting plate 1, the first slider bracket 3 and the second slider bracket 13 are respectively welded to the side plate 2, and the protective cover mounting plate 14 is welded to the middle of the side plate 2.

[0033] In the embodiment of the present application, a first slider bracket hole 15 is provided on the first slider bracket 3 , and a first slider bracket hole 15 is provided on the second slider bracket 13 .

[0034] Specifically, the first slider bracket hole 15 is used to install the U-shaped hook 4 .

[0035] In the embodiment of the present application, a slider bracket rail 17 is provided on the first slider bracket 3 , and a slider bracket rail 17 is provided on the second slider bracket 13 .

[0036] Specifically, the slider bracket rail 17 is used for the U-shaped hook to slide.

[0037] In the embodiment of the present application, a second slider bracket hole 16 is provided on the first slider bracket 3 .

[0038] Specifically, the second slider bracket hole 16 is used to install the U-hook disassembly assembly.

[0039] In the embodiment of the present application, the U-shaped hook 4 includes a locking tongue 5 and an operating handle 6, which is a prior art and will not be described in detail. The locking tongue 5 can pop out and retract in the first slider bracket hole 15 of the first slider bracket 3 and the second slider bracket 13.

[0040] Specifically, the U-shaped hook 4 is fixed in the first slider bracket hole 15 through the locking tongue 5 .

[0041] In an embodiment of the present application, the U-hook disassembly and assembly assembly includes: a hexagonal flange nut 7, a spacer 8, a hexagon socket screw 9 and a compression spring 10, wherein the spacer 8 is arranged on the towing bracket 12, the hexagonal flange nut 7 and the hexagon socket screw 9 are connected, and the compression spring 10 is arranged between the spacer 8 and the hexagon socket screw 9.

[0042] Specifically, the U-hook disassembly and assembly assembly consists of a hexagonal flange nut 7, a spacer 8, a hexagon socket screw 9, and a compression spring 10, wherein the spacer 8 is welded to the first slider bracket 3, the hexagon socket screw 9 is connected to the hexagonal flange nut 7 through the second slider bracket hole 16 and the inner hole of the spacer 8, and the hexagon socket screw 9 and the hexagonal flange nut 7 are connected together by spot welding, and the compression spring 10 is installed between the spacer 8 and the hexagon socket screw 9.

[0043] In the embodiment of the present application, a hexagon socket bolt slideway 11 is provided on the towing bracket 12 , and the hexagon socket screw 9 is at least partially inserted into the hexagon socket bolt slideway 11 .

[0044] When the U-shaped hook 4 is disassembled, the hexagonal flange nut 7 is manually pulled to move to the left, and the hexagonal screw 9 moves to the left along the hexagonal screw slide 11. At this time, the compression spring 10 placed between the pad 8 and the hexagonal screw 9 is compressed. When the hexagonal screw 9 moves to the left until the head of the hexagonal screw 9 is completely inside the second slider bracket hole 16, the operating handle 6 is manually operated to retract the locking tongue 5 of the U-shaped hook 4, and the U-shaped hook 4 slides from the first slider bracket 3 and the second slider bracket 13 along the slider bracket track 17. When the U-shaped hook 4 passes the U-shaped hook disassembly assembly, the hexagonal flange nut 7 is loosened, and the hexagonal screw 9 rebounds under the action of the compression spring 10, and part of the head of the hexagonal screw 9 is placed in the slider bracket track 17, and the head contacts the rightmost side of the hexagonal screw slide 11. After the U-shaped hook 4 moves to the specified position, the operating handle 6 is loosened, the locking tongue 5 of the U-shaped hook 4 pops out and extends into the first slider bracket hole 15, and the U-shaped hook 4 is fixed. In addition, when the U-shaped hook 4 needs to be moved within the slider bracket track 17 according to actual working conditions, the head of the hexagon socket screw 9 placed within the slider bracket track 17 can prevent the U-shaped hook 4 from falling off due to operational errors during the movement process, thereby avoiding injuries to workers. When the U-shaped hook 4 is removed, the operation is reversed.

[0045] The U-shaped hook disassembly and assembly structure provided in the embodiment of the present application has a simple structure and flexible operation, which improves the convenience of disassembly and assembly of the U-shaped hook; no other tools are required during disassembly and assembly, which improves operability and convenience and improves work efficiency; it has stable performance and a long service life, avoids thread stripping caused by repeated disassembly and assembly, and is convenient for manual operation.
