[0018] The structure of the electric tool torque detector provided by the present utility model is as Figure 1 and Figure 3 shown, including a detection table 1. Four Fukuma wheels 11 are installed at the bottom of the detection table 1. The Fukuma wheels 11 facilitate the movement and fixation of the detection table 1. A detection mechanism 3 is installed on one side of the surface of the detection table 1. The detection mechanism 3 is used for the torque detection of the electric tool; the detection mechanism 3 includes a support plate 31 and a torque sensor 32. The support plate 31 is fixedly connected to the surface of the detection table 1, and the top end of the support plate 31 is connected to the torque sensor 32. Four groups of locking screws 311 are arranged on the surface of the torque sensor 32. One end of the locking screw 311 passes through the torque sensor 32 and the support plate 31 and is threadedly connected with a locking nut 312. The locking screw 311 cooperates with the locking nut 312 to fix the torque sensor 32 on the surface of the support plate 31.

[0019] During implementation, insert the twisting end of the electric tool to be detected into the torque sensor 32 on the surface of the support plate 31, start the electric tool to twist the torque sensor 32, and the torque sensor 32 will detect the torque.

[0020] Furthermore, as Figure 2 and Figure 3As shown in the figure, a control mechanism 2 is provided on the lower surface of the top of the detection table 1. The control mechanism 2 is composed of a control box 21, a box cover 22, a PLC controller 23 and a transmitter 24. The control box 21 is fixedly connected to the surface of the detection table 1, and the PLC controller 23 and the transmitter 24 are respectively installed inside the control box 21. The output end of the torque sensor 32 is electrically connected to the input end of the transmitter 24, and the output end of the transmitter 24 is electrically connected to the input end of the PLC controller 23.

[0021] During implementation, the torque sensor 32 transmits the detected signal to the transmitter 24 inside the control box 21. The transmitter 24 converts the output signal of the sensor into a signal that can be recognized by the controller and transmits it to the PLC controller 23.

[0022] Further, as Figure 2 and Figure 4 shown in the figure, a display mechanism 4 is provided on one side of the detection table 1 away from the detection mechanism 3. The display mechanism 4 includes an adjustment component 41 and a display screen 42. The adjustment component 41 is connected to the surface of the detection table 1, and the display screen 42 is installed at the top of the adjustment component 41. The display screen 42 is used for post-detection display work. The adjustment component 41 is composed of a base 411, adjustment pieces 412 and a mounting seat 413.
