Description

Hand tool combination structure capable of extending and adjusting torque

This creation is about the technical field of a hand tool, in particular, a hand tool combination structure that can change the driving direction, can extend the driving arm, and can adjust the output torque to extend and adjust the torsion.

Generally, the hand tool is made of a metal material, and the handle body is used as a force arm, and a suitable force can be used to form a driving torque for screwing or loosening a workpiece. In addition to being applied to the locking of mechanical devices or mechanisms, such hand tools can also be used as medical tools.

Regardless of the field in which the hand tool is applied, one of the ways to increase the output torque is to increase the user's exertion. However, this method obviously has a laborious effect on the user, and it is not easy to control the output torque. Another way is to increase the length of the arm, however the handle is mostly a solid metal body and the handle does not provide a mechanism for extending the length.

In addition, fixed-length hand tools may not be suitable for some locking elements that are hidden in a deep position, or where the operator's hand is not suitable for contact with the peripheral position of the workpiece.

The purpose of this creation is to solve the shortcomings of traditional hand tools that do not have an extended length.

The purpose of the present invention is to provide a hand tool assembly structure capable of extending and adjusting the torsion force, which has the effect of extending the length of the tool body, thereby increasing the length of the force arm to improve the output torque and reduce the operation force.

The purpose of this creation is to provide a hand tool combination structure capable of extending and adjusting the torsion force, which has the effect of accurately controlling the output torque by adjusting the preset output torque of the adjustment torque sleeve.

In addition, the tool body of the present invention has an extension effect, so that the locking element hidden in the deep position can be locked or loosened, and the probability of the operator's hand contacting the peripheral position of the workpiece can be reduced.
