According to what I have previously known, the torque wrench structure that I have used is also a patent that I have assigned. For example, the US patent number: US8863624B2, the Taiwan patent application number: 103215530, the certificate number: M492808, the patent name: with locking device The structure of the patent is: a torque wrench with a locking device, which includes: a hollow main rod body 10; a tool member 20; a torque adjusting elastic member 40; a clutch assembly 50; and a The locking device 60 is arranged on the outer periphery of the second end 12 of the main rod body 10, and produces relative axial movement along the main rod body 10 between a locked position and a non-locked position, wherein , The locking device 60 includes a metal locking ring 61, a compression spring 62, a metal C-shaped buckle 63, and at least one metal positioning bead 65.

But the shortcomings of this conventional torque wrench structure are:

1. Please supplement as shown in Figures 6 to 8 of the US Gazette. When you want to adjust the torque value, move the locking ring 61 to the direction of the adjusting handle 30 to make the locking device 60 slide To non-locking position The compression spring 62 is compressed due to the displacement of the locking ring 61, so that the C-shaped buckle 63 is engaged with the ring groove 614 to position the locking ring 61 in the non-locking position, and the positioning bead 65 is Without being pushed by the pushing surface 612 and corresponding to the inclined surface 616, the positioning bead 65 can move between the accommodating groove 611 and the positioning groove 13, and the adjusting handle 30 can be opposed to the main rod body 10 However, when the adjusting handle 30 is rotated relative to the main rod body 10 to adjust the torque value, the adjusting handle 30 is rotated without any warning sound that can be emitted for the purpose of understanding the torque wrench The current torque status is not convenient for manipulation.

2. The positioning groove 13 is hidden in the adjusting handle 30. When the adjusting handle 30 is rotated, the positioning bead 65 may not be aligned with one of the positioning grooves 13, and the displacement of the locking ring 61 will not make the The positioning bead 65 is accommodated in the positioning groove 13, and the locking ring 61 cannot be returned to the locked position, which is inconvenient for operation.

In view of the shortcomings of the above-mentioned conventional structure, the inventors have used many years of experience in manufacturing, production and design in related industries to finally have a product with a torque wrench structure that can solve the disadvantages of the conventional use.

In the conventional torque wrench structure, when the grip should be adjusted When rotating relative to the main rod body to adjust the torque value, the adjusting handle is rotated without any prompt sound that can be emitted when rotating. In the torque wrench structure of the present invention, the positioning member is supported by the second ring body When the elastic restoring force is placed in the next positioning groove, the sound of entering the positioning groove will occur, and the positioning between the positioning part and each positioning groove will generate a prompt sound for understanding and adjusting the torque wrench The situation.

The present invention relates to a torque wrench structure, which The system includes: a first system with an accommodation groove, a first through groove, a first ring groove and a bead holding groove; a second system with a driving part and a plurality of positioning grooves; a control sleeve ring system The spring groove, the second tapered groove, the first abutting edge, the first peripheral surface, the first tapered groove, and the second peripheral surface are sequentially provided; an elastic element springs against the control sleeve Ring; a positioning member is accommodated in the first through groove, the positioning member is hidden in the control collar, the positioning member can be locked or not locked in the positioning groove, the positioning member is A third ring groove is provided, and the third ring groove is in the shape of a concave ring groove; a second ring system is sleeved on the third ring groove, and the positioning member is also restricted by the second ring body and does not come out The first piercing groove outside.

When the control collar axially moves to the non-locking position When the first system can rotate relative to the second body, the positioning member can be displaced on the second body to be positioned at any positioning groove. When the positioning member moves from one positioning groove to the next positioning When the groove is located, the positioning member is pushed by the outer peripheral surface of the second body to prop up the second ring body. When the positioning member is aligned with the next positioning groove, the positioning member is supported by the second ring body. When the elastic restoring force is placed in the next positioning groove, a sound entering the positioning groove will occur, and the positioning between the positioning member and each positioning groove will generate a prompt sound. When the positioning member is further accommodated in the positioning groove, the elastic restoring force of the second ring body is accommodated. The displacement path of the positioning member is based on the elastic restoring force of the second ring body. The positioning of the curved surface of the groove is performed, so the sound of the positioning member is more reliable, and the sound of the positioning member is restricted by the second ring body when the positioning member is displaced can be smoother.
