[0046] The use process of the present invention:

[0047] First, build the template mounting frame, put the tension screw 9 in place, install the nut state detection assembly on each tension screw 9 in turn, and then insert each movable support plate 13 into the fixed block in the vertical back rib 3, and insert the movable latch 14 to fix it, and then connect the linear motor 16 and the device connected thereto to several movable support plates 13, and then place the control box 31 on the bottom plate 2, connect the control circuit and power supply circuit of the control box 31, and then start it for use;

[0048] The pressure sensor 36 monitors the tightening force of each tension nut 10. When it is found that the pressure at a tension nut 10 decreases, it means that the tension nut 10 is loose. The controller 33 first controls the warning light 35 and the warning speaker 34 to start and issue a warning. At the same time, it controls the linear motor 16 to start and drive the fixed seat 17 to move toward the tension nut 10 with the problem. At the same time, the photoelectric sensor transmitter 30 at the loose tension nut 10 is turned on. When the fixed seat 17 reaches the correct position, the photoelectric sensor receiving head 29 receives the photoelectric sensor signal. The linear motor 16 stops moving when the sensor transmitter 30 sends a signal. At this time, the sleeve 22 is opposite to the tension nut 10, and then the electric cylinder 19 starts to extend, driving the fastening box 21 to move forward, so that the sleeve 22 is connected to the tension nut 10, and then the fastening motor 23 is started to drive the sleeve 22 to rotate, and the tension nut 10 is tightened. After the pressure sensor 36 detects that the pressure value returns to normal, the warning speaker 34 and the warning light 35 are turned off, and the fastening motor 23 is stopped to control the electric cylinder 19 to retract, and the fastening of the tension nut 10 is completed;

[0049] In special cases, when the external power supply is disconnected, the device uses the power in the battery 32 to operate, and the battery 32 can be recharged after the power supply is restored;

[0050] In unexpected circumstances, such as installation errors or damage to the fastening structure, the tension nut 10 cannot be tightened in time. At this time, the warning speaker 34 and the warning light 35 will continue to issue warnings, and nearby operators can discover the problem in time and correct it by manually tightening it. Then the warning light 35 and the warning speaker 34 are turned off, and the device can be repaired or adjusted.

[0051] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
