[0026] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part 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 creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 7 As shown, a quick disassembly and assembly tool for preventing bolts from rotating in the embodiment of the first aspect of the utility model comprises a bolt clamping structure 1, a hexagonal socket 2, a cam handle 3, a cam structure 4, a spring 7 and a holding portion 9; one end of the cam handle 3 is provided with a cam structure 4, and the other end is bent to form a holding portion 9, one end of the bolt clamping structure 1 is hinged at the center of the cam structure 4, and the other end is embedded with a hexagonal socket 2, and the middle part of the cam handle 3 is connected to the middle part of the bolt clamping structure 1 through a spring 7.

[0029] In the above embodiment, it should be noted that, when in use, a hexagonal socket 2 is provided on one side of the bolt clamping structure 1 according to the bolt specifications for clamping on the nut, and a round hole is provided on the other side for installation with the center hole of the cam structure 4 of the cam handle 3; the cam handle 3, as the core structure of the tooling, is a key component for quick disassembly and assembly, and the other side is a cam structure 4, which is connected to the bolt clamping structure 1 through the middle round hole; when the nut is rotated, the cam high point of the cam structure 4 contacts the abutment position, and after the bolt is tightened, by pulling the cam handle 3, the cam structure 4 rotates along the pin, so that the cam low point contacts the abutment position, thereby unloading the pressure between the cam structure 4 and the abutment position generated by the rotation of the nut, so that the tooling can be easily removed; a spring 7 is used to tighten the bolt clamping structure 1 and the cam handle 3 together, so that the cam high point can contact the abutment relay position in a natural state, thereby preventing the cam handle 3 from shaking at will during the tightening of the bolt.

[0030] During the specific implementation process:

[0031] like Figure 4 As shown, when the bolt is tightened, there should be a structure near the nut to prevent the tooling from heeling and rotating against the reaction force;

[0032] like Figure 5 As shown in the figure, before tightening the bolt, the sleeve of the anti-rotation tool should be put on the nut to be worked;

[0033] like Figure 6 As shown, after the bolt is tightened, the tooling rotates with the nut, and the high point of the cam contacts the abutment position;

[0034] like Figure 7 As shown, by pulling the cam handle 3, the cam structure 4 rotates along the pin, and the contact position is converted from the cam high point to the cam low point. The pressure at the abutment position is unloaded, and the tooling can be easily removed.

[0035] The technical effect achieved by the above-mentioned embodiments is as follows: through a quick disassembly and assembly tool for preventing bolts from rotating, a hexagonal sleeve is used to clamp the nut, and the tool can be easily installed; a cam with a cam handle is used to lean against the lever position around the bolt to quickly unload the pressure generated by the rotating bolt, and the tool can be easily disassembled; a spring-pull bolt clamping structure and a cam handle are used to prevent the two from shaking relative to each other during the tightening process of the bolt, thereby facilitating operation.

[0036] Example 2

[0037] like Figures 1 to 7 As shown, a quick disassembly and assembly tool for preventing bolts from rotating includes all the contents of Example 1. In addition, a concave U-shaped notch is provided on the side edge of the bolt clamping structure 1, and the "U"-shaped notch is used to avoid the bolt in the middle position during empty assembly.

[0038] Optionally, a pin 5 is further included, and the bolt clamping structure 1 is connected to the central circular hole of the cam structure 4 via the pin 5 .

[0039] The technical effects achieved by the above embodiment are: the overall design is a U-shaped notch for avoiding the bolt in the middle position; the pin 5 is used for connection, which improves the flexibility and smoothness of the rotation of the bolt clamping structure 1 and the cam structure 4.

[0040] Example 3

[0041] like Figures 1 to 7 As shown, a quick disassembly and assembly tool for preventing bolts from rotating includes all the contents of Example 2. In addition, the cam handle 3 and the holding portion 9 form an overall "L"-shaped bending structure.

[0042] Optionally, the outer surface of the grip portion 9 is covered with a soft rubber cover.

[0043] The technical effects achieved by the above embodiments are as follows: the overall "L"-shaped bending structure formed by the cam handle 3 and the holding portion 9 increases the overall mechanical strength of the two; and the comfort of holding the holding portion 9 is increased by providing a soft rubber sleeve.

[0044] Example 4

[0045] like Figures 1 to 7 As shown, a quick disassembly and assembly tool for preventing bolts from rotating includes all the contents of Example 3. In addition, a column A6 is protruded on the surface of the bolt clamping structure 1, and the column A6 is located near the end of the bolt clamping structure 1 where the cam structure 4 is hinged. One end of the spring 7 is hung on the column A6, and the other end of the spring 7 is installed in the middle of the cam handle 3.

[0046] Optionally, column B8 is located beside column A6, and column B8 is used to limit the cam handle 3.

[0047] The technical effects achieved by the above embodiment are as follows: by setting the column A6, the installation of the spring 7 is facilitated; by setting the column B8, the cam handle 3 is limited, so that the cam handle 3 and the bolt clamping structure 1 are initially in a fixed position relationship.

[0048] Example 5

[0049] like Figures 1 to 7 As shown, a quick disassembly and assembly tool for preventing bolts from rotating includes all the contents of Example 4. In addition, the distance between the high point of the cam structure 4 and the end of the bolt clamping structure 1 is greater than the distance between the low point of the cam structure 4 and the end of the bolt clamping structure 1.

[0050] Optionally, the bolt clamping structure 1 is a sheet-like structure cut from a steel plate.

[0051] Optionally, the cam handle 3 is a sheet-like structure cut from a steel plate.

[0052] The technical effects achieved by the above embodiments are as follows: by making the bolt clamping structure 1 into a sheet-like structure cut from a steel plate, the mechanical strength and service life of the bolt clamping structure 1 are significantly improved; by making the cam handle 3 into a sheet-like structure cut from a steel plate, the mechanical strength and service life of the cam handle 3 are significantly improved.
