The centripetal moving clamping assembly 6 is a key component responsible for clamping the object to be operated, realizing the centripetal clamping action of the object, and ensuring the stability of the object to be operated during the operation. The moving clamping plate 12 directly contacts and clamps the object to be operated, and moves centripetally or away from each other under the drive of the double-headed screw 19, ensuring the stability of the object during the operation.

[0033] In this embodiment, the fastening components 7 are symmetrically disposed on the outer walls of both sides of one end of the expander plate 4 away from the wrench end 3. The fastening components 7 penetrate into the clamped area 5 to centripetally clamp and abut against the moving clamping plates 12, so that when the two moving clamping plates 12 centripetally clamp the object, they are in close contact with the object. The fastening components 7 are used to assist in fastening the centripetal moving clamping assembly 6, providing an additional clamping force, ensuring that the object to be operated is firmly clamped, and enhancing the stability of the centripetal moving clamping assembly 6.

[0034] In this embodiment, behind the clamped area 5 and inside the expander plate 4, there is an installation chamber 18 for accommodating the double-headed screw 19. At both ends of the smooth rod of the double-headed screw 19, there are interference fits with bearings 21, and the bearings 21 are embedded inside the expander plate 4. The double-headed screw 19 drives the moving clamping plates 12 to move centripetally or away from each other, realizing the clamping action, and ensuring the reliable clamping of the object to be operated.

[0035] In this embodiment, one end of the double-headed screw 19 extends to the outside of the expander plate 4 and is fixedly installed with a nut knob 11, so that when the nut knob 11 is screwed, the double-headed screw 19 rotates in the installation chamber 18 in cooperation with the two bearings 21. The nut knob 11 is used to manually adjust the double-headed screw 19, facilitating the user's operation to change the position of the moving clamping plate 12 and realizing a quick and precise adjustment of the clamping force.

[0036] In this embodiment, on the outer peripheral sidewalls at both ends of the double-headed screw 19, there are external thread paths 20 with opposite thread directions. The two moving clamping plates 12 are respectively connected through the two external thread paths 20, so that the two moving clamping plates 12 move away from each other or centripetally. The external thread paths 20 are used to cooperate with the moving clamping plates 12 to realize the movement of the moving clamping plates 12 away from each other or centripetally, ensuring the smoothness of the clamping action.

[0037] In this embodiment, the fastening member 7 includes two fastening screw members 13, and both of the two fastening screw members 13 penetrate into the clamped area 5 and abut against the back surface of the movable clamping plate 12. The fastening screw member 13 is used to fasten the movable clamping plate 12, providing an additional clamping force and enhancing the stability of the clamping assembly.

[0038] In this embodiment, template members 15 are connected to the opposite side surfaces of the two movable clamping plates 12 through magnetic detachable members, and clamping cavities 16 for accommodating the clamped object are provided on the opposite side surfaces of the two template members 15.

[0039] In this embodiment, the magnetic detachable member includes a magnetic absorption installation groove 14 opened on the inner wall of each movable clamping plate 12 and a magnet absorption block 17 fixedly installed on the back surface of the template member 15. When installing the template member 15, the magnet absorption block 17 fits into the magnetic absorption installation groove 14 and undergoes magnetic attraction. The magnet absorption block 17 is used to cooperate with the magnetic absorption installation groove 14 to realize the quick installation and disassembly of the template member 15, improving the flexibility of the device.

[0040] In this embodiment, a wrench rectangular clamping block 9 is integrally connected to the bottom surface of the wrench end 3.

A locking anti-loosening bolt 10 is threadedly connected upward from the bottom surface of the expander plate member 4 and aligned with the wrench rectangular clamping block 9. The screw end of the locking anti-loosening bolt 10 extends into the wrench rectangular clamping block 9, while the nut end of the locking anti-loosening bolt 10 abuts against the bottom surface of the expander plate member 4 to lock the expander plate member 4 and prevent the expander plate member 4 from detaching from the wrench rectangular clamping block 9. The wrench rectangular clamping groove 8 is used to connect with the wrench rectangular clamping block 9 to ensure the reliable connection between the expander plate member 4 and the wrench end 3 and prevent the expander plate member 4 from accidentally falling off. The locking anti-loosening bolt 10 is used to lock the connection between the expander plate member 4 and the wrench end 3, providing a reliable locking mechanism to ensure that the connection part does not loosen during use.

[0041] Working principle:

[0042] For this multi-functional torque wrench expander, prepare the multi-functional torque wrench assembly 1, ensure that the torque wrench member 2 and the wrench end 3 are in a usable state, check whether the expander plate member 4 has been correctly installed on the wrench end 3, and confirm that the locking anti-loosening bolt 10 has been tightened to prevent the expander plate member 4 from separating from the wrench end 3. According to the size and shape of the object to be operated, select a suitable template member 15 and connect it through the magnet absorption block 17 and the magnetic absorption installation groove 14 on the movable clamping plate 12, and confirm that the clamping cavity 16 on the template member 15 matches the size of the object to be operated.

[0043] Place the object to be operated into the clamping cavity 16 within the clamping area 5. By screwing the nut knob 11, drive the double-headed screw 19 to rotate. The rotation of the double-headed screw 19 drives the two moving clamping plates 12 to move towards each other through the external thread path 20, achieving centripetal clamping. The fastening screw member 13 in the fastening component 7 abuts against the back surface of the moving clamping plate 12 to ensure that the object to be operated does not slide stably during the clamping process. Use the torque wrench member 2 to rotate the wrench end 3, thereby driving the object to be operated in the clamping area 5 to rotate, achieving fastening or loosening operations.

[0044] Screw the nut knob 11 in the reverse direction to make the double-headed screw 19 rotate in the reverse direction. The moving clamping plates 12 move away from each other to release the object to be operated. Take out the object to be operated. If it is necessary to replace the template member 15, just remove the magnet suction block 17 from the magnetic suction installation groove 14 to replace the new template member 15. If it is necessary to disassemble the expander plate member 4, first loosen the locking anti-disengagement bolt 10, and then take out the expander plate member 4 from the wrench rectangular clamping groove 8.
