Abstract
The present invention provides a torque wrench with digital display for torque adjustment, including a main body, a wrenching member, a trigger mechanism, a torque adjustment device, and a torque sensing device. The torque adjustment device includes an elastic member, a moving member, a transmission gear, and a modulating member. The modulating member rotationally drives the transmission gear to rotate, so as to drive the moving member to generate a linear displacement, thereby adjusting the support position of the moving member with respect to the elastic member, achieving an efficient torque value adjustment effect and purpose.
Claims13
A torque wrench with digital display for torque adjustment, comprising:
- a main body comprising a first end and a second end away from the first end;
- a wrenching member pivotally disposed on the main body and able to sway with respect to the main body, the wrenching member comprising a wrenching part exposed out of the main body and a connecting part pivotally connected with the first end of the main body, the connecting part comprising a contacting end away from the wrenching part;
- a trigger mechanism disposed in the main body and contacting the contacting end of the connecting part;
- a torque adjustment device disposed in the main body and connected with the trigger mechanism, the torque adjustment device being operated by a user to adjust a predetermined torque, the torque adjustment device comprising an elastic member, a moving member, a transmission gear, and a modulating member, the elastic member comprising a fixing end and a free section connected with the fixing end, the fixing end is fixed to the trigger mechanism, the moving member is slidably disposed in the main body along an axis direction of the main body, the moving member comprises an abutting part, against which the free section abuts when bearing a force imposed thereon, the moving member comprising a first tooth part disposed along a direction in parallel to the axis, the transmission gear comprising a second tooth part which is engaged with the first tooth part, the modulating member being connected with the transmission gear, the modulating member being configured to be rotated by the user to drive the moving member to generate a linear sliding relationship with respect to the main body, facilitating an positional adjustment of the abutting part with respect to the free section;
- a torque sensing device disposed on the main body corresponding to the position of the torque adjustment device, the torque sensing device being configured to sense a displacement variation of the moving member, so as to display a torque value on a digital display.
