Torsion indicating wrench

Abstract

The invention provides a torsion indicating wrench which comprises the components of a body with a pulling part and a supporting part, wherein the pulling part can drive a working member, and the bodyhas a radial line which divides the torsion indicating wrench area into a counterclockwise-side area and a clockwise-side area; a torsion rod which comprises a first end and a second end, wherein thefirst end of the torsion rod is connected with the supporting part, an offset segment is formed between the first end and the second end of the torsion rod, the axis of the offset segment exists in the counterclockwise-side area, the second end of the torsion rod can be pulled by a user so that the offset segment of the torsion rod is elastically bent in a direction from the counterclockwise-sidearea to the clockwise-side area; and an indicating device which is arranged between the body and the torsion rod, and when the offset segment of the torsion rod elastically bends from the counterclockwise-side area to the clockwise-side area, the user can observe a torsion value.

Description

technical field [0001] The invention relates to a small torque wrench, in particular to a torque indicating wrench which takes up little space. Background technique [0002] Such as figure 1 As shown, it is the structure of the existing fine-tuning torque wrench, which is mainly composed of a handle 1, an action rod 2, a pointer 3, an action head 4 and an indicator plate 5. The handle 1 and the actuating head 4 are respectively arranged at both ends of the actuating rod 2, and the indicator piece 5 is fixed on the actuating rod 2, wherein one end of the pointer 3 is set on the actuating head 4, and the other end corresponds to and points to the indicating piece 5. In this way, when force is applied to the handle 1, the action rod 2 will bend under the torsion force, while the pointer 3 remains straight, and the user can observe the magnitude of the torsion force by pointing the pointer 3 to the scale on the indicator sheet 5 . [0003] However, the pointer 3 of the aforeme...

Problems solved by technology

[0007] Although the aforementioned torque wrench 20 has no exposed pointer, it is still T-shaped as a whole, and still has the problem of occupying space, making it difficult to carry and store.

[0008] Moreover, all the above-mentioned existing wrenches use the pointer to swing in a small angle and draw a torque indicating scale, but due to the small angle, the scale that can be divided is limited, and it is not easy for the operator to judge the torque.
