The disassembly part 1 has a connecting hole, which is used to connect with the stud to be disassembled; the clamping part 2 is connected to the disassembly part 1, and the clamping part 2 has a clamping groove 3, which is connected to the connecting hole, and the stud extends into the connecting hole through the clamping groove 3; the locking assembly 4 is movably connected to the clamping part 2, and the locking assembly 4 is adjusted to move relative to the clamping part 2 to change the diameter of the clamping groove 3.

[0033] In the embodiment of the present application, the disassembly portion 1 has a connection hole, the clamping portion 2 is connected to the disassembly portion 1, the clamping portion 2 has a clamping groove 3, the clamping groove 3 is connected to the connection hole, the stud extends into the connection hole through the clamping groove 3, the locking assembly 4 is movably connected to the clamping portion 2, and the locking assembly 4 is adjusted to move relative to the clamping portion 2 to change the diameter of the clamping groove 3. During the disassembly of the stud, the diameter of the clamping groove 3 is adjusted, the clamping portion 2 is first sleeved on the stud, and moved forward to connect the disassembly portion 1 with the stud, after the clamping portion 2 moves to the preset position, the diameter of the clamping groove 3 is adjusted again to clamp the stud in the clamping groove 3, and the disassembly portion 1 is reversely screwed to disengage the stud from the fixed position. After the clamping part 2 and the disassembly part 1 of the above-mentioned disassembly tool are connected to the screw to be disassembled, the stud bolt is disengaged from the fixed position by reversely twisting the disassembly part 1, which not only does not damage the thread structure of the stud bolt, but also makes the entire disassembly process simple, fast and easy to operate.

[0034] It should be noted that the clamping portion 2 can be a split structure or an integrally formed structure, and the clamping groove 3 can be adjusted by operating the locking assembly 4 .

[0035] Exemplarily, the clamping portion 2 is a split structure, and the clamping portion 2 includes two components. The two components of the clamping portion 2 are arranged to form a clamping groove 3. The locking assembly 4 is operated to change the relative distance between the two components, thereby adjusting the diameter of the clamping groove 3.

[0036] Exemplarily, the clamping portion 2 is an integrally formed structure, the clamping portion 2 is bent to form the clamping groove 3, one side of the clamping portion 2 has a notch, and the clamping assembly is operated to change the width of the notch, thereby adjusting the diameter of the clamping groove 3.

[0037] In the embodiment of the present application, the clamping part 2 is a split structure, and the clamping part 2 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 is connected to the disassembly part 1, and the second clamping member 22 is connected to the disassembly part 1. The second clamping member 22 is arranged opposite to the first clamping member 21, and the second clamping member 22 is arranged at a distance from the first clamping member 21 to enclose and form a clamping groove 3. The locking assembly 4 is respectively connected to the first clamping member 21 and the second clamping member 22, and the locking assembly 4 is adjusted to move relative to at least one of the first clamping member 21 and the second clamping member 22 to change the diameter of the clamping groove 3.

[0038] Specifically, the first clamping member 21 and the second clamping member 22 have the same structure, both of which are plate-like structures. Taking the first clamping member 21 as an example, a groove is provided in the middle of the first clamping member 21, and the groove is arranged through the length direction of the first clamping member 21. The groove of the first clamping member 21 and the groove of the second clamping member 22 are arranged opposite to each other to form a clamping groove 3. By adjusting the relative distance between the first clamping member 21 and the second clamping member 22, the diameter of the clamping groove 3 can be adjusted.

[0039] It can be understood that the first end of the first clamping member 21 is connected to the disassembly portion 1, and the second end of the first clamping member 21 is a free end; the first end of the second clamping member 22 is connected to the disassembly portion 1, and the second end of the second clamping member 22 is a free end; under the action of external force, the first clamping member 21 and the second clamping member 22 are deformed so that the two are relatively close. Among them, the locking assembly 4 is arranged close to the free ends of the first clamping member 21 and the second clamping member 22.

[0040] Furthermore, the locking assembly 4 includes a fastening bolt 41 and a fastening nut 42. The fastening bolt 41 passes through the first clamping member 21 and the second clamping member 22. The fastening nut 42 is threadedly connected to the fastening bolt 41. The fastening nut 42 is screwed to adjust the position of the first clamping member 21 or the second clamping member 22 relative to the fastening bolt 41 to change the diameter of the clamping groove 3.

[0041] It should be noted that when the first clamping member 21 is arranged close to the fastening nut 42, screwing the fastening nut 42 only adjusts the position of the first clamping member 21 relative to the fastening bolt 41; when the second clamping member 22 is arranged close to the fastening nut 42, screwing the fastening nut 42 only adjusts the position of the second clamping member 22 relative to the fastening bolt 41.

[0042] In the embodiment of the present application, the second clamping member 22 is arranged close to the fastening nut 42, and the fastening nut 42 is screwed to push the second clamping member 22 to deform toward one side of the first clamping member 21, so that the diameter of the clamping groove 3 becomes smaller and the stud bolt to be removed is clamped. The second clamping member 22 is arranged close to the fastening nut 42, and the fastening nut 42 is screwed to push the second clamping member 22 to deform toward one side of the first clamping member 21, so that the diameter of the clamping groove 3 becomes larger and is separated from the stud bolt to be removed.

[0043] Furthermore, the clamping groove 3 has at least two groove planes, and the at least two groove planes are arranged opposite to each other. The stud bolt to be disassembled is clamped by the two oppositely arranged groove planes to prevent the stud bolt and the clamping groove 3 from being displaced.

[0044] Furthermore, the radial cross section of the clamping groove 3 is a polygon. That is, the radial cross section of the clamping groove 3 can be a triangle, a quadrilateral, a pentagon, a hexagon, etc.

[0045] In the embodiment of the present application, the radial cross section of the clamping groove 3 is a hexagonal structure, that is, the clamping groove 3 abuts against the stud bolt to be removed through the groove plane.

[0046] Furthermore, the connection hole of the disassembly part 1 is a threaded hole, and the disassembly part 1 is used for threaded connection with the stud. Through the threaded connection, the connection between the disassembly part 1 and the stud is more stable.

[0047] Furthermore, the radial cross section of the disassembly part 1 is a hexagonal structure, which is convenient for connecting with the disassembly part 1 by a hexagonal wrench, and the stud bolt can be separated from the fixed position by reversely twisting the disassembly part 1.

[0048] Furthermore, a protective pad is laid on the groove surface of the clamping groove 3. The clamping groove 3 abuts against the stud bolt through the protective pad to prevent the clamping groove 3 from damaging the thread of the stud bolt.

[0049] Furthermore, the protective pad is made of rubber material. The clamping groove 3 is in contact with the stud bolt through the rubber material, which not only avoids damaging the thread of the stud bolt, but also provides a pre-tightening force to make the connection between the clamping groove 3 and the stud bolt more compact.

[0050] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0051] 1. After the clamping part 2 and the disassembly part 1 of the disassembly tool are connected to the screw to be disassembled, the stud bolt is separated from the fixed position by reversely twisting the disassembly part 1, which not only does not damage the thread structure of the stud bolt, but also makes the whole disassembly process simple, fast and easy to operate.

[0052] 2. The radial cross section of the disassembly part 1 is a hexagonal structure, which is convenient for connecting with the disassembly part 1 through a hexagonal wrench, and the stud bolt can be released from the fixed position by twisting the disassembly part 1 in the reverse direction.
