Description

Wrench jig

The present invention relates to a wrench jig for fastening or disassembling a bolt to a member to be fastened. In particular, when fastening or disassembling the bolt, the operator's pressing force is not transmitted to the bolt, thereby preventing damage to the bolt and other parts. That is about the wrench jig.

Generally, a wrench (or spanner) is a tool used when fastening or disassembling various bolts or nuts.

Such wrenches have already been proposed and used in various forms to select and use those suitable for the characteristics of the parts fastened to the respective mechanical parts.

In other words, various mechanisms or parts require various bolts and nuts to fasten them organically, and these machines or parts are indirectly provided when fastening fastening members such as batts or nuts to which they are organically fastened. Due to the rotational torque, a mechanical device or a component, which is to be fastened, may be damaged or may not be able to fully function.

Therefore, when fastening fastening members suitable for each machine or parts, a fastening device capable of imparting a suitable fastening force so that a rotating torque of too large force (or too small force) is not imparted to the machine or parts to be fastened. Should be used.
