Description

torque wrench

The present invention relates to a torque wrench.

Press, the general torque wrench is usually available to set the torque value, so that it can select the appropriate torque setting value according to the assembly and disassembly process of various components. The conventional torque wrench has a driving head at one end of the body, and the torque wrench body The other end is provided with a central push rod to adjust the torque setting value, and an adjustable rotating member is installed at this end. When the rotating member is rotated, the central push rod will be driven by the rotating member to move axially, thereby adjusting the torque The torque setting value of the wrench, and then the user can perform the locking operation, such as the patent described in the patent number TWM540019. In order to prevent the rotating member from rotating arbitrarily, the rotating member can slide along the axial direction in a locked position and a In the release position, when it is in the locked position, the teeth of the rotating piece are locked against the teeth of the main body, and the rotating piece cannot be rotated. The rotating part can be rotated only when the locking teeth of the piece do not abut against the locking teeth of the main body.

However, after a conventional torque wrench is used for a period of time, the rotating part is easy to loosen and cause any sliding relative to the main body. In this way, during the use of the torque wrench, the rotating part tends to move to the release position by itself, causing the torque wrench to The change of the torque setting value will cause errors in the operation, and there are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive torque wrench to solve the above problems.

The main purpose of the present invention is to provide a torque wrench, the torque wrench has an adjustment piece, the adjustment piece is screwed to lock or release the rotation of the rotating piece, so it can ensure that the adjustment piece does not arbitrarily release the rotation of the rotating piece Rotate to avoid errors in operation.

In order to achieve the above object, the present invention provides a torque wrench, which includes a body, a driving part, a positioning member, a torque adjusting component, a rotating component, an adjusting component and a latching component. The body defines an axis. The driving part is arranged at one end of the main body, and when the driving part receives a torsion force greater than a torque setting value, an idling phenomenon occurs. The positioning piece is fixed in the body. The torque adjustment assembly is movable along the axial direction to adjust the torque setting value. The rotating member is rotatably assembled with the torque adjusting component relative to the main body, so as to drive the torque adjusting component to move along the axial direction. The adjusting member is screwed on the rotating member along the axial direction. The latching component includes a first latching portion and a second latching portion, the first latching portion is disposed on the positioning member, and the second latching portion is disposed on the rotating member and can be relative to the rotating member along the The axial slide is between a first position and a second position. Wherein, when the second latching portion is located at the first position, the second latching portion is not latched against the first latching portion; the second latching portion can be driven to move by screwing the adjusting member When reaching the second position, the second engaging portion is engaged with the first engaging portion.
