Description

Tool support structure

The invention relates to a hand tool, in particular to a supporting structure of a tool that can support the working head.

Generally, when tightening or loosening the workpiece, in order to be able to produce a reverse idling operation during use, a ratchet wrench is used. Please refer to FIG. 1, which provides a conventional ratchet wrench 90, including: a ratchet The head 91 and a shaft 92 are formed. The ratchet head 91 can produce a ratcheting effect, that is, a single direction can generate a rotating force, and the other direction is idling, so that the ratchet wrench 90 can be repeated back and forth It can rotate, and can produce unidirectional force application. In addition, in order to produce the effect of reversing force control, the ratchet head 11 will be provided with a reversing mechanism 911 on the top. Through the switching of the reversing mechanism 911, Generate force operations with different directions.

While the conventional ratchet wrench 90 is in operation, in order to operate stably, the user usually holds the shaft 92 with one hand to apply force, and then holds the ratchet head 91 with the other hand. When the shaft 92 rotates, the hand holds the ratchet head 91 to increase its stability, so as to avoid that the ratchet head 91 and the workpiece are not combined and cannot be actuated during force application.

However, while the user's hand is applying force and gripping, in addition to the process of applying force, the hand holding the ratchet head 91 is easy to dial to the reversing mechanism 911, so that the position of the reversing mechanism 911 changes, As a result, the ratchet teeth in the ratchet head 91 are incompletely engaged and damaged.

In addition, in a state where the locking torque is required to be used accurately, the ratchet wrench 90 is provided with a torque mechanism (not shown). The torque value can be measured through the torque change between the shaft 92 and the ratchet head 91, When the hand is held on the ratchet head 91 and the shaft 92 rotates, the hand held on the ratchet head 91 will cause interference, so that the torque value measured by the torque mechanism will be Holding the hand on the ratchet head 91 generates damping, which causes an error in the measurement of the torque value.

The main object of the present invention is to provide a tool support structure that can be supported by the hand but does not affect the operation of the tool.
