FIGS. 5 and 6 show the fitting portion ₁ and the torque-electricity converting member 3 similar to the tightening member.
It shows a spanner-type tightening member that can be removably fixed to the end ₃₂ of the holder, and a 12-sided wrench with a ratchet function.

Claims

[Scope of Claim for Utility Model Registration] 1. A tightening member is removably fixed to one end of a tubular handle member, and one end of a torsion bar having a strain gauge fixed to its effective diameter is fixed to the tightening member, The other end of the handle member is formed flat, a protective case consisting of several parts is attached to this part, and a digital display circuit connected to the strain gauge and a battery for power supply are housed inside, as well as switches and a digital display. A torque wrench that features a window etc. 2. A wrench head, spanner head, etc. having a ratchet mechanism is removably fixed to one end of the tightening member, a strain gauge is fixed to both sides of a leaf spring provided in the middle, and the other end is detachably attached to the tubular handle member. The torque wrench as claimed in Claim 1 of the utility model registration, characterized in that the torque wrench is fixedly mounted and a strain gauge is connected to the digital display circuit. 3. An elastic sealing material such as rubber is crimped at the joint between the tightening member and the tubular handle member, the joint between the protective case, the joint between the protective case and the tubular handle member, and the end opening of the tubular handle member. A torque wrench according to claims 1 and 2 of the utility model registration, which is characterized by:
