[0050] Reference Figure 3 and Figure 4 In a preferred embodiment, the contact switch 209 is electrically connected to the rare-earth permanent magnet motor 103 via a wire, and the torque sensor 203 and the electric push rod 208 are both electrically connected to the small PLC controller 207 via wires.

[0051] Specifically, by setting up a small PLC controller 207, the purpose of precise torque control can be achieved.

[0053] Specifically, by setting the connecting block 2011 and the connecting groove 2012, it is easy to quickly connect the torque sensor 203 and the sliding column 205.

[0054] Reference Figure 3 and Figure 4 In a preferred embodiment, the outer surface of the rotating shaft 204 is provided with a through-connecting groove 2012 insertion hole, the inner wall of the insertion hole is fixed with a bolt 2013, and the surface of the connecting block 2011 is provided with a limiting hole that is adapted to the bolt 2013 and slides in connection with the surface of the bolt 2013, and the surface of the bolt 2013 is threaded with a locking nut 2014.

[0055] Specifically, by setting bolts 2013 and locking nuts 2014, it is easy to fix the rotating shaft 204 and the sliding column 205.

[0056] Reference Figure 3 and Figure 4 In a preferred embodiment, the control component 200 further includes a rotating disk 2015 rotatably disposed on the outer surface of the sliding column 205, and a spring 2016 fixed on the lower surface of the rotating disk 2015. A telescopic frame 2017 is fixedly disposed on the surface of the cylindrical housing 101, and the telescopic end surface of the telescopic frame 2017 is fixedly connected to the surface of the torque sensor 203 by screws.

[0057] Specifically, by setting the rotating disk 2015 and the spring 2016, the rotating disk 2015 can be moved when the wrench body 100 is pressed, so that the rotating disk 2015 contacts the contact switch 209, thereby achieving the purpose of automatically controlling the rare earth permanent magnet motor 103 to open. At the same time, the setting of the spring 2016 prevents the rotating disk 2015 from moving away from the contact switch 209 when the wrench body 100 is not working.

[0058] In this embodiment, by setting the control component 200, the torque value of the torque sensor 203 can be preset in advance through the small PLC controller 207 during actual use. After the socket is connected to the socket connecting shaft 102 and fitted onto the screw end of the mounting part, the wrench body 100 can be pressed, causing the rectangular insert 201 to move within the rectangular groove 2010. When the rectangular insert 201 is inserted into the bottom of the rectangular groove 2010, the surface of the rotating disk 2015 can contact the contact switch 209. At this time, the contact switch 209 automatically controls the rare earth permanent magnet motor 103 to rotate. The mechanism achieves automatic tightening. During the tightening process, the torque sensor 203 monitors the torque in real time. When the torque reaches the preset value, the torque sensor 203 transmits a signal to the small PLC controller 207. The small PLC controller 207 automatically controls the electric push rod 208 to retract, causing the contact switch 209 to disengage from the rotating disk 2015. At this time, the contact switch 209 automatically controls the rare earth permanent magnet motor 103 to shut down, thereby achieving precise control of the tightening torque and effectively protecting the rare earth permanent magnet motor 103.

[0059] Working principle: In actual use, the wrench allows the socket to be fitted onto the socket connecting shaft 102. Then, the wrench is lifted, and the other end of the socket is engaged with the screw end at the installation location. The rotation of the rare-earth permanent magnet motor 103 drives the socket connecting shaft 102 to rotate, thus achieving automatic tightening. This reduces the workload of personnel and meets the tightening requirements of large-size screws on high-voltage transmission towers, making it highly practical. Furthermore, in actual use, the torque value of the torque sensor 203 can be preset via a small PLC controller 207. After connecting the socket to the socket connecting shaft 102 and fitting it onto the screw end at the installation location, pressing the wrench body 100 causes the rectangular insert 201 to move within the rectangular groove 2010. When the rectangular insert 201... When the 01 is inserted into the bottom of the rectangular slot 2010, the surface of the rotating disk 2015 can contact the contact switch 209. At this time, the contact switch 209 automatically controls the rare earth permanent magnet motor 103 to rotate, achieving the purpose of automatic fastening. During the fastening process, the torque can be monitored in real time by the torque sensor 203. When the torque reaches the preset value, the torque sensor 203 transmits the signal to the small PLC controller 207. The small PLC controller 207 automatically controls the electric push rod 208 to retract, causing the contact switch 209 to disengage from the rotating disk 2015. At this time, the contact switch 209 automatically controls the rare earth permanent magnet motor 103 to turn off, thereby achieving the purpose of precise control of the fastening torque and effectively protecting the rare earth permanent magnet motor 103.
