New description: [New technical field] This creation is related to the torque wrench. In more detail, it refers to a kind of controllable adjustment screw and adjustment knob between the rotation or limit, so as to facilitate A torque wrench that corrects the torque display value and adjusts the torque. [Prior Art] Lu Xizhi's torque wrench has a hollow main body, and two ends are respectively provided with a tool member for fitting a screw or bolt and a rotatable adjusting grip, the main rod is in the body A clutch assembly and a spring are further disposed between the tool member and the adjusting grip, and the torque value and the indicating scale are provided at the joint of the main rod body and the adjusting grip. Wherein, the adjusting grip can be pushed against the spring by a rotating action to change the pre-stress of the spring, and the clutch assembly can generate a clutching action when the torsion force of the tool member is greater than the elastic pre-stress of the spring. To limit the torque of the tool. Moreover, the clutch assembly can generate a tripping knocking sound during the clutching action to remind the user of excessive force application. So that the snail # cap or bolt is damaged. ' However, the adjustment grip is rotated to the top by an adjustment screw to change the pre-stress of the spring. There is a device between the adjustment grip and the adjustment screw. Rotate the two to the limit to prevent the adjustment of the adjustment between the grip and the adjustment screw, resulting in incorrect torque adjustment. Moreover, the device also has the function of being severable: it is idling, so that it can be used to correct the torque value and indicate the scale display value. & [New content] 3 M434652 This solution can control the adjusting screw to have the convenience of correcting the torsion.

[Embodiment] For the convenience of description, the central idea expressed in the column of the above novel content is expressed by a specific embodiment. The various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual components, as set forth above. In the following description, like elements are denoted by the same reference numerals. Referring to the first to fourth figures, the present invention provides a torque wrench comprising: a hollow main body 10 comprising a first end 11 and a second end 12; a tool member 20 The adjusting screw 30 includes an abutting end 31 that can be screwed on the second end 12 of the main rod body 10, and an adjusting screw 30. The driving end 5 M434652 32; wherein the second end 12 is fixed with a screw hole block 33, and a screw hole 331 is formed in the center of the screw hole block 33 for screwing with the adjusting screw 30; 40, which is disposed in the main rod body 10 and directly or indirectly abuts against the abutting end 31 of the adjusting screw 30, for example, at least one slider 41 abuts between them; a clutch assembly 50, It is disposed between the torsion adjusting elastic member 40 and the tool member 20, and is configured to generate a clutching action; and an adjusting grip 60 having a shaft hole 61 therethrough for receiving the driving end 32 of the adjusting screw 30 And the adjustment grip 60 is rotatably coupled to the second end 12; wherein the second end 12 is The outer peripheral edge is provided with at least one torque value scale 121, and the adjustment grip 60 is provided with at least one indicator scale 601 corresponding thereto. Furthermore, a convex ring 62 protrudes from the inner wall surface of the shaft hole 61; a first screw member 63, a positioning piece 64 and a second screw member 65 are sequentially disposed on the driving end 32, and the first screw member And the positioning piece 64 is respectively disposed on the two sides of the convex ring 62; wherein the driving end 32 is recessed with a groove 321 parallel to the axial direction thereof, and the positioning piece 64 is provided with a groove 321 The positioning block 641 is disposed on the side of one of the protruding rings 62 and is provided with a plurality of positioning ribs 642. A fixing seat 66 for accommodating the first screw member 63 is further disposed in the shaft hole 61 between the first screw member 63 and the protruding ring 62. The outer circumference ring of the fixing seat 66 is provided with a plurality of anti-slip grooves 661, and the inner wall of the shaft hole 61 of the adjusting grip 60 is fixed. And the fixing seat 66 is recessed with a corner groove 662 for the first screw 63 to accommodate the yak 63 system as a hex nut, and the corner groove 662 is available for the first screw 63 Each end angle is stuck. After clarifying the detailed structure of the above case, the following is a detailed description of the action of the case: ', as shown in the second; third, fifth and fifth figures, the first screw 63 accommodates the corner groove 662, when the fixing seat 66 and the adjusting grip 6 are tightened, the second screw 65 is screwed to the first screw member 642. The positioning piece 64 is pressed against the convex ring 62. And the positioning ridges can enhance the occlusion effect of the first screw 63, the fixing seat %, the fixing 64 and the adjusting ring 62 of the adjusting grip 6 紧固 are integrally fastened. And the function of fitting the block 641 into the groove 321 is such that the adjustment grip 6 can drive the adjusting screw 30 to generate a screw rotation on the screw hole block 33. As shown in the fifth figure, when the adjusting screw 3 is rotated in the screw hole of the screw hole block 33, the axial displacement can be generated by the screwing action (as shown in FIG. 2, the adjusting screw 3 is offset to the top end). 31 changing the pre-stress of the torsion adjustment spring 4 to achieve the adjustment of the torque value of the clutch assembly 50 to generate the clutch action. Further, when the torque value scale 121 and the corresponding indication scale 6〇1 are in error or need to be corrected, The second screw member 65 can be screwed loosely opposite to the direction of the first screw member 63, so that the positioning piece M and the convex ring ^ are loosely released. At this time, when the adjusting grip 60 is rotated, the adjusting screw 3 is not adjusted. Drive 'so does not change the torque value' but the torque value scale i2i and the indicator scale 601 can change the corresponding position, in order to adjust the correct display torque M434652 force value. After the adjustment is completed, only need to re-tighten the second screw Therefore, when the first screw 63, the positioning piece 64 and the second screw 65 are locked to each other on both sides of the convex ring 62, the rotation between the adjusting screw 30 and the adjusting grip 60 can be controlled. Limit to ensure that the adjustment screw 30 and the adjustment grip 60 are idling The problem is that when the above components are loosely released, the work of correcting the torque display value can be performed to ensure the accuracy of the torque display value. Although the present invention is described in a preferred embodiment, it can be understood by those skilled in the art. Various changes may be made without departing from the spirit and scope of the invention. The embodiments described above are only intended to illustrate the present invention and are not intended to limit the scope of the present invention. Changes are all in the scope of this creative intention. [Simplified illustration] The first picture is a three-dimensional appearance of the creation.
