The sensing component is disposed in the strainable region of the torque wrench, and generates a signal when the strainable region is deformed; the control and the signal processing system electrically connect the sense, the J component, and the sensed sfl wave generated by the sensing component— Relative to the physical quantity, the display device is controlled by the edge control and signal processing system to display the relative physical quantity. The display device uses an LED display and a 〇LED display. However, it should be considered that the torque wrench can be insufficiently accommodated in the cage field, and the display device needs to be clothed with its exclusive outer casing before being assembled on the outside of the torque wrench; the display device is obviously convex. Outside the strained area of M405341, a part that is extremely vulnerable to external force is formed, and the display device is easily damaged. In addition, the setting of the sensing element is related to the accuracy of the torsional response, but the problem is that the torsion force (4) can be applied to the surface of the surface or the arc surface, and the feeling is sincerely attached to such a surface. The measurement capability is weakened. 'The sensed torque is usually less than the actual tightening force of the wrench on the screw', causing a destructive torsional force to occur, or the screw tightening preload is too large. In addition, 'the author's number is not the same as the number of torques on the || is limited by the ambient light and the angle of view. 'The ambient light must be sufficient, the angle of view must be orthogonal, and the number is the most complete. In other words, when the ambient light and the viewing angle condition (4) are satisfied, the number of the operator's visual observation may be incomplete, which may cause misjudgment of the torque value. [New content] Based on the above discussion, the solution required for the whole creation is required. The four major topics, which are how to reduce the size of the display device, can be fully accommodated in the limit of the shaft of the torque wrench; the second is how to improve the tangible tangles of the torque wrench __; The third is how to make the torque value of the digital display read correctly; the fourth is how to make the digital display be stably installed on the shaft of the torque wrench with simple assembly means. The case reaches the reduced display volume and the surgical plan, mainly to start In the selection of the display module, the liquid crystal display module (LCD) replaces the conventional LED display and the OLED display, and the thinned and miniaturized backlight module is arranged to reduce the display. The purpose of the volume, and further reduce the size of the outer casing, so that the entire display module can be placed in the confined space of the shaft of the torque wrench 'protected by the rigid strainable area of the force wrench. This case achieves the enhanced sensing element The technical solution of adhesion stability is to provide a flat groove on the surface of the corrugated surface of the curved surface or the circular arc surface, to limit the sensing element in the groove, and to make the M405341 and the plane of the groove completely The contact can fully sense the torque change of the strainable area, the sensitivity of the gain sensing, and the torque sensed by the sensing element and the actual tightening force of the wrench on the screw: The case reaches the correct value of the residual torque The technical solution of reading mainly focuses on the LCD screen and the backlight module _ optional, relying on the LED system as the system, and has the LCD screen size and miscellaneous illuminating surface, the f-light module increases the lcd _ Show brightness, and expand the angle of view of the big coffee. In the low light operating environment, the operator can clear the material_force value by the brightness of the display, and the sight ship (4) on the LCD screen, The author's Lu Tu's line can read the *torque value even if it is not with the screen. This case achieves the technical solution of installing the digital display with a simple assembly means on the torsion wrench shaft. - the combination means is mounted on the upper cover, the upper cover has a wire corresponding to the opening σ shape preset by the shaft of the twisted hand, and the upper cover and the shaft are combined with the second combination means 'the upper cover completely seals the opening σ, and the tilting display The module is placed in the interior of the shaft and protected.

The grip 63 has a variety of independent items suitable for gripping according to the requirements of the wrench. In the wrench manufacturing assembly stage, a suitable grip 63 is assembled to the _ end of the shaft 61, and the port between the assembly chamber is set on the shaft. The upper cover 7Q of the liquid crystal display module of 61 is separated from each other by a predetermined distance, and is formed separately from the shaft 61 without any interference with the liquid crystal display module 1, and is applied to the grip of the grip 63. The force is not transmitted to any improper external force of the liquid crystal display module. In summary, the technical solution for reducing the size of the display in this case is to replace the conventional LED display and the 〇LED display with a liquid crystal display module, and to configure the thinned backlight module 2 〇 and the liquid crystal screen 30' to reduce the display volume. The purpose of the 'step-by-step reduction of the size of the outer casing, so that the entire display module can be set in the limited space t of the shaft 66 (or strainable area) of the torque wrench 6Q, the rigid shaft of the torque wrench 61 (or strainable area) protection. In this case, a strainable area is defined on the surface of the tool head of the torque wrench 6〇. Since the surface of the tool head is a curved surface, a flat groove 65 is provided in the secret domain to limit the sensing element to the concave surface. Contact with the _ time surface (4), and the torque change of the sensing strainable region 66 is 'gain sensing sensitivity, so that the torque sensed by the sensing tillage is equal to the actual tightening force of the wrench to the screw. ' M405341 The backlight module 20 of the present invention can increase the display brightness of the LCD screen and expand the viewing angle of the liquid crystal screen 30. In the low light operating environment, the operator can use the brightness of the liquid crystal screen. The torque value can be clearly read, and the operator's line of sight can clearly read the torque value even if it is not orthogonal to the screen within the half angle angle of the viewing angle allowed by the liquid crystal screen 3Q. In this case, the liquid crystal display module is made by the first combination means. The upper cover 7G is combined with the upper cover 7G, and the liquid crystal age module is disposed in the shaft 61 through the preset opening σ 64 of the torque wrench 60. The upper cover 7 is packaged and fixed to the opening by the second combination means. 64. The liquid crystal display module is packaged and protected by the shaft 61. The combination method of the first age means is simple and easy to implement. Although the shaft Μ is pre-configured with an opening 64, the upper cover 〇 The opening is encapsulated in the opening to compensate for the discontinuity of the structural surface of the shaft due to the opening 64. Therefore, the rigidity of the shaft 61 is not affected.
