Embodiment Construction

[0023] The present invention relates to a measurement structure of an electronic torque wrench, please refer to figure 1 and figure 2 As shown, it mainly includes a driving part 10, a grip part 20 and a measuring unit 30; wherein:

[0024] One end of the driving part 10 is provided with a driving head 11, which is sleeved with a sleeve or screwdriver bit (not shown in the figure) required for the pulling operation, and the other end is provided with a coupling section 12, which is a cylinder The joint section 12 is provided with a long and narrow slot 13. The slot 13 passes through the axis of the joint section 12 and runs through the joint section 12. The plane of the slot 13 and the plane where the screw member (not shown) pulled by the driving head 11 is located. Vertical, and one end of the coupling section 12 is the bottom surface 14, the cut groove 13 runs through the bottom surface 14 to form two semicircles, the driving part 10 is provided with a perforation 15, and ...

Abstract

The invention provides a measuring structure of an electric torsion wrench, mainly comprising a driving part, a gripping part and a measuring unit; wherein, one end of the driving part is provided with a driving head and the other end is provided with a binding segment which is provided with a long dissection slot; one end of the binding segment is a bottom surface and the dissection slot goes through the bottom surface; the gripping part is provided with a containing space for the insertion of the binding segment; and the measuring unit is arranged at the bottom surface and stretches across the dissection slot. The structure can achieve the effects of increasing strain values and simultaneously reducing the error amount, improving the sensitivity and decreasing structural damages.

Description

technical field [0001] The invention relates to a wrench, in particular to an electronic torque wrench measurement structure with high sensitivity, reduced measurement error, accurate measurement of torque value, and reduced damage to the body structure. Background technique [0002] For the existing electronic torque wrench measurement structure, please refer to US Patent No. 3970155 and No. 4006629. The strain gauge is directly attached to the side of the integral wrench neck. When stress is applied to the electronic torque wrench, the wrench neck A corresponding strain change is generated, and the resistance change signal of the strain gauge is sent to the working circuit, and the working circuit calculates the torque value of the electronic torque wrench according to the signal. However, if the integral wrench is damaged during operation or the measuring component is damaged, the damaged part cannot be replaced, and a new product must be purchased. Furthermore, when the...
