Description

Torque wrench

This creation is related to a torque wrench, especially a torque wrench that can provide a variety of fixed torque and different torque values by simply adjusting the force applied arm in the torque.

Press, the general torque wrench is also called torque wrench or torque wrench. The torque (L) = force arm (D) × force (F), the upper limit of the torque value needs to be set when the screw or bolt is locked or disassembled. In order to prevent damage of the screw or bolt due to excessive force application, the torque wrench is generated as shown in the first and second figures, and the socket wrench 1 is mainly pivoted to the grip 11 One end of the grip 11 is provided with a torsion jumping mechanism 12, and the end of the torsion jumping mechanism 12 is abutted by a pressure spring 13 whose end is restrained by an adjusting seat 14 and The surface of the grip 11 is provided with a torque value display numeral 15. Thus, by adjusting the position setting of the seat 14, the pressure formed by the end of the pressure spring 13 to the torque trip mechanism 12 is set to conform to the set of the socket wrench 1. Torque value, when the nut is locked, when the nut is applied by the socket wrench 1 to reach the set torque value (when the torque is greater than the pressure set by the pressure spring), the torque tripping mechanism 12 will instantaneously Disconnected to produce a sound to inform the user of the utility However, the nut size in the workplace is different, and the required torque value is different. Therefore, the relative position of the adjusting seat 14 needs to be adjusted due to the difference in the torque value to adjust the pressure applied to the pressure spring 13 and by the torque. The value displays the scale display of the number 15 to provide the user with the adjustment identification, thus, by turning the grip 11 is stopped until the pressure required by the pressure spring 13 is stopped. Although it can be used to provide a socket wrench that provides a plurality of different torque values, the grip 11 is rotated until the action of the pressure spring 13 is complicated, and the value of the torque 15 is displayed by the torque value. The display shows the torque value and is identified by manpower. There will still be some errors. Over time, the screw or bolt will still be damaged.
