With the above structure, the torque sensor detects the torque, and transmits the torque information to the display screen 221 through the controller, and then the torque information is displayed under the action of the display screen 221.

[0035] It should be noted that the torque sensor on the disassembly and assembly tool of the present application uses strain electrical measurement technology to detect torque. Specifically, strain gauges are pasted on the elastic shaft inside the handle to form a measurement bridge. When the elastic shaft is subjected to torque, it will produce a small deformation, which will cause a change in the resistance value of the bridge. The resistance change of the strain bridge will be converted into a change in voltage signal, thereby realizing the measurement of torque.

[0036] In other embodiments, the torque sensor uses a strain gauge to measure torque. When an object is subjected to torque, it will deform. The torque sensor measures the deformation through the strain gauge installed on the object to be tested. Specifically, the torque sensor includes a rotating shaft and two springs. When torque is applied to the rotating shaft, it will cause the springs to deform. The strain gauge records the amount of deformation of the springs and converts it into an electrical signal.

[0037] In this embodiment, the disassembly and assembly tool further includes a power source, which is arranged inside the handle 21. The power source is electrically connected to the display member 22, the torque sensor, and the controller respectively. With the above structure, setting the power source inside the handle 21 can provide electrical energy for the display member 22, the torque sensor, and the controller, ensuring the normal operation of the torque sensor and the display screen 221.
