Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments, but the present invention is not limited to these embodiments.
As shown in fig. 1, 2 and 3, a torque wrench comprises a handle, the handle comprises an upper wrench rod 1 and a lower wrench rod 1 with the same structure, and an upper wrench head 2 and a lower wrench head 2 respectively fixed at the front end of the wrench rods, the upper wrench head 2 and the lower wrench head 2 are provided with positioning screw holes 3 at corresponding positions, the upper wrench rod 1 and the lower wrench head 2 are fixedly connected into a whole by positioning screws penetrating the positioning screw holes 3, the upper wrench head 2 and the lower wrench head 2 are both ring-shaped, a first inner cavity (not shown) is formed at the central part of the assembled upper wrench head 2 and lower wrench head 2, a wrench chuck 4 is embedded in the first inner cavity, clamping grooves 5 are evenly distributed on the circumference of the wrench chuck 4, an inner working surface 6 capable of being matched with a workpiece is arranged at the center part of the wrench chuck 4, a second inner cavity 7 is arranged at the center part of the upper wrench rod 1 and lower wrench rod 1 after being assembled, an axial positioning mechanism is arranged in the second inner cavity 7 along the axial direction of the wrench rod 1, and the axial positioning mechanism is connected with the wrench chuck 4 in a sliding mode through a sliding block 8.
