Description

Torque tool with full rotation

technical field

The invention relates to an all-round rotating torque tool.

Background technique

The existing torsion tool is shown in FIG. 4 . The torsion tool has a hollow handle 6 and a hollow shaft 61 , which uses a second rod 611 located in the hollow shaft 61 by rotating the handle 6 . A first rod 612 is supported by a steel ball 62, so that the second rod 611 can press the first rod 612 by the steel ball 62, thereby changing the torque output value of the torque tool.

However, although the aforementioned torsion tool can tighten the first rod 612 by means of the steel ball 62, due to the movement of the steel ball 62 between the two inclined surfaces 613, the contact between the steel ball 62 and the two inclined surfaces 613 will not be sufficient when tightening. The area is a point contact, so the steel ball 62 will bear a huge force, and then cause the service life of the torque tool to be short.

Furthermore, the pressing effect is performed by the steel ball 62 moving between the two inclined surfaces 613, so that the head 63 extending from the first rod 612 farther than the second rod 611 can only be twisted in one direction. The effect, relatively, limits the utility of the torque tool.

Therefore, how to improve the practicability and service life of this torsion tool is the focus of creation of the present invention.

Detailed ways

Referring to Fig. 1 to Fig. 3, the structure of the selected embodiment of the present invention is shown in the figure.

The omni-directional torsion tool of present embodiment, as shown in Figure 1 and Figure 2, it is to comprise:

A hollow handle 1, which has a freely rotatable handle portion 11 and a connecting portion 12 of a torque observer 121;

A hollow shaft 2, one end of which is connected to the connecting portion 12, and the inside of the shaft 2 has a first rod 21 and a second rod 22, the first rod 21 has a first end 211 and a second end 212, the first end 211 of the first rod 21 is opposite to the second end 222 of the second rod 22, and a first groove 213 is recessed at the first end 211 of the first rod 21, corresponding to the first A Groove 213 A second groove 223 is defined at the second end 222 of the second rod 22 to form a generally rhombus-shaped accommodating space 23 for a rotating member 24 to be accommodated in the accommodating space 23 . In this embodiment, the rotating member 24 refers to a steel ball, so that the first rod 21 and the second rod 22 form a supporting shape, and the end of the shaft rod 2 away from the connecting portion 12 is provided with a joint portion 25, And the joint portion 25 is recessed with a mounting groove 251 . In this embodiment, the mounting groove 251 is in the shape of a pyramid for mounting a head 3 , and an annular groove 26 is formed around the mounting groove 251 for accommodating a positioning member 4 .
