[0038] For this simple torque wrench adapter, the contact between the wrench head 7 and the object. The shape of the wrench head 7 is designed to fit tightly with the bolt or nut to be operated, ensuring the accuracy of torque transmission. When the user rotates the handle part 4 of the wrench, the torque is transmitted through the wrench rod body 3 to the wrench head 7, and then acts on the bolt or nut to be operated. By adjusting the length of the handle part 4 or using different extension rods, the magnitude of the torque can be changed to meet different operation requirements.

[0039] The docking of the installation docking block 15 and the installation docking bayonet 14. By inserting the installation docking block 15 into the installation docking bayonet 14, the preliminary connection between the wrench head 7 and the connecting plate member 9 is realized. The tightening of the first locking bolt 10 is achieved by passing the first locking bolt 10 through the locking hole 16 to fasten the installation docking block 15 and the installation docking bayonet 14 together, ensuring the stability of the connection. The installation of the U-shaped clamp member 8. The U-shaped clamp member 8 is covered from the top surface of one end of the wrench rod body 3 close to the wrench head 7, aligned with the top of the connecting plate member 9, and fixed by the second locking bolt 13 to further enhance the stability of the connection.

[0040] The fixed vertical plate 11 is welded to the bottom of the wrench rod body 3 for fixing the micro damper 18 and the buffer spring member 19. The micro damper 18 and the buffer spring member 19 work together to absorb the vibration and impact generated during the operation, reduce the fatigue of the user, and improve the comfort and accuracy of the operation. The tail end of the handle part 4 is provided with a connectable docking slot 5 and is equipped with a connection hole 6 for docking and connecting with other extension rods or accessories, so as to realize the extension of the torque transmission distance or the expansion of functions. Check whether all components are intact, install the U-shaped clamp member 8 in place and fix it with the second locking bolt 13, insert the installation docking block 15 into the installation docking bayonet 14 and fasten it with the first locking bolt 10, and install the micro damper 18 and the buffer spring member 19 on the fixed vertical plate 11.

[0041] Align the wrench head 7 with the bolt or nut to be operated, use the handle part 4 to rotate the wrench, and the torque is transmitted through the wrench rod body 3 to the wrench head 7. During the operation, the micro damper 18 and the buffer spring member 19 absorb the vibration and impact. If it is necessary to extend the torque transmission distance, an extension rod can be connected through the connectable docking slot 5 and the connection hole 6. After the operation is completed, release the first locking bolt 10 and the second locking bolt 13 for quick adjustment or disassembly during the next use, and clean and maintain all components to ensure they are in good condition for the next use.
