Description

Torque post

The present invention relates to a torsion post, in particular to a post structure that is guided between a wrench head and a sleeve to detect a torque value when the drive is driven, and the display screen has an unrotated rotation. The perspective adjustment function of the influence.

According to the technical field of mechanical assembly, bolts and nuts are used to lock various components, which is a relatively well-known fixing method. However, because each person's feeling of strength is not the same, and some special combinations are not as tight as possible, so there is a torque wrench to ask the market, so that every screw lock operation, even in different people Under the operation, the same torque requirement can also be achieved; however, the torque wrench has a pure mechanical design. When the user applies a force close to the preset torque value, the torque wrench will generate a swinging feel. The user is reminded that there is also an electronic torque wrench with a display module for the user to obtain information about the torque value through the display module.

Please refer to the "Digital Torque Post" of the Patent No. M392714 of the Republic of China, which mainly comprises a torsion post having a first adapter body and a second adapter body, the first transfer The rod body has a first joint portion and a first joint portion.
