[0035] Example 1:

[0036] like Figures 1 to 5 As shown, this embodiment proposes a special quick wrench for removing the top support, including: a main body 1, a cover plate 3, a fixing bolt 5, an adjusting nut 6 and a disassembly component 7. A through hole is opened in the middle of the main body 1 to facilitate the insertion of other components.

[0037] The side of the main body 1 is fixedly connected with a handle 2, which facilitates to increase the rotating torque and reduce the pressure on the hands of the user. The cover plate 3 is arranged above the main body 1. A limiting hole is arranged in the middle of the upper side of the cover plate 3 and cooperates with a through hole. The diameter of the limiting hole is smaller than that of the through hole. Two fixing bolts 5 penetrate the cover plate 3 and the main body 1 and are threadedly connected with the cover plate 3 and the main body 1, so as to facilitate the disassembly and assembly of the cover plate 3 and the main body 1, and facilitate the subsequent maintenance and replacement. The adjusting nut 6 is arranged below the main body 1. A screw thread is arranged on the inner wall of the adjusting nut 6. In actual use, the adjusting nut 6 is sleeved on the lead screw and threadedly cooperates with the side wall of the lead screw. By rotating the adjusting nut 6, the adjusting nut 6 can move along the lead screw, so as to adjust the position of the adjusting nut 6.

[0038] The disassembly assembly 7 is arranged on the upper side of the main body 1. A fixing sleeve 71 is rotatably connected to the inner wall of the through hole. The upper side of the outer wall of the fixing sleeve 71 is movably connected with the cover plate 3. Two clamping grooves are arranged on the lower end of the side wall of the fixing sleeve 71 and are used for sleeving a ratchet wheel 72 which cooperates with the main body 1 on the upper side of the outer wall of the fixing sleeve 71. The ratchet wheel 72 is fixedly connected with the outer wall of the fixing sleeve 71. Two pawls 73 are rotatably connected to the upper side of the main body 1. The pawls 73 are sleeved on the fixing bolts 5 and are rotatably connected with the side walls of the fixing bolts 5. A spring 74 which cooperates with the main body 1 is fixedly connected to one side of the pawl 73. The side of the spring 74 away from the pawl 73 is fixedly connected with the upper side of the main body 1, so as to provide a counterforce, so that the pawl 73 can always keep in close contact with the ratchet wheel 72, and the ratchet wheel 72 can only rotate counterclockwise. By abutting the lower side of the fixing sleeve 71 with the adjusting nut 6, then reciprocally rotating the main body 1, under the cooperation of the ratchet wheel 72 and the pawl 73, the fixing sleeve 71 can drive the adjusting nut 6 to rotate, so as to adjust the ground clearance. There is no distance limit. The adjusting nut 6 can be arranged at any position or removed from the lead screw, so as to improve the practicability of the device.

[0039] Embodiment 2

[0040] The scheme in Embodiment 1 will be further introduced in combination with a specific working mode. Details are described below:

[0041] The upper side of the cover plate 3 is threadedly connected with four inner hexagonal bolts 4 which penetrate the cover plate 3 and the main body 1. By rotating the inner hexagonal bolts 4, the cover plate 3 can be disassembled and assembled, so as to facilitate the user to maintain and replace each component on the lower side of the cover plate 3, and improve the practicability of the device.

[0042] Embodiment 3

[0043] The scheme in Embodiment 2 will be further introduced in combination with a specific working mode. Details are described below:

[0044] The inner wall of the limiting hole is fixedly connected with an annular plate 31 used in cooperation with the fixing sleeve 71, and the inner wall of the annular plate 31 is movably connected with the adjusting nut 6, so that the further limiting of the adjusting nut 6 can be realized through the annular plate 31, and the stable movement of the adjusting nut 6 during use is ensured.

[0045] Working principle: firstly, the opening of the fixing sleeve 71 is aligned with the opening of the cover plate 3 and the opening on one side of the main body 1, then the wrench is moved to the top support to be adjusted, so that the screw rod enters the through hole, then the wrench is moved downward, so that the fixing sleeve 71 abuts against the adjusting nut 6, then the handle 2 is reciprocatingly rotated, so that the adjusting nut 6 is driven to move along the screw rod under the cooperation of the ratchet wheel 72 and the pawl 73, the ground clearance is adjusted, after completion, the handle 2 is rotated clockwise, and is lifted upward, so that the opening of the fixing sleeve 71 is consistent with the opening direction of the cover plate 3 and the opening on one side of the main body 1, then the wrench is taken off from the screw rod, and the use process of the device is completed.

[0046] The above describes the utility model and its implementation mode, and the description is not limited, and the embodiment shown in the drawings is only one of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the creative purpose of the utility model, similar structure modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
