[0002] A torque device for nut assembly is a tool used to install nuts. It is usually used to install nuts on bolts. A torque device for nut assembly can help ensure that the nut is installed correctly. A torque device for nut assembly usually consists of a handle and a torsion mechanism. The torque can be transmitted to the nut through the torsion mechanism. When the set torque value is reached, the device will make a sound or vibrate to remind the operator to stop applying torque to prevent the nut from being over-tightened.

[0006] The adjusting mechanism includes a slider slidably connected to the inside of the rectangular groove, a rectangular block fixedly connected to one end of the slider, and a groove opened on one side of the slider, the inner wall of the groove is fixedly connected to two springs, the interior of the two springs is sleeved with a buffer rod, one end of the two springs is fixedly connected to a movable block, one side of the movable block is rotatably connected to two connecting rods, one end of the two connecting rods is rotatably connected to a semicircular plate, one side of the semicircular plate is fixedly connected to two movable plates, one side of the surface of the two movable plates is fixedly connected to a rotating rod, and the surfaces of the two rotating rods are rotatably connected to both sides of the surface of the rectangular block
