[0038] Please see Figure 2As one embodiment of this utility model, a tightening gun assembly 17 and an industrial control all-in-one machine 18 are provided on the upper part of the frame 1, and a screw storage box 19 is provided on the lower part of the frame 1 near the outer side of the guide bar 8.

[0039] In the above-described solution, the tightening gun assembly 17 is mounted above the frame 1, a crucial position as it allows the operator to tighten screws on the workpiece at the optimal angle and height. The tightening gun assembly 17 typically includes the tightening gun itself, a power supply, and a control system, all carefully assembled to ensure the accuracy and efficiency of the tightening process. During operation, the operator inputs tightening parameters via an integrated industrial control computer 18. The tightening gun tightens the screws on the workpiece according to the input parameters. After tightening is complete, the tightening gun automatically stops working and may issue a signal notification. The screw storage box 19 is located below the frame 1, near the outer side of the guide bar 8. This location is chosen to facilitate easy access to screws by the operator and to ensure the safety of the screws during storage and transportation. When screws need to be tightened, the operator takes an appropriate number of screws from the screw storage box 19 and places them into the feeding mechanism of the tightening gun assembly 17. The feeding mechanism automatically delivers the screws to the working position of the tightening gun, and then the tightening gun begins to tighten the screws. Through reasonable design and configuration, the stability and reliability of the tightening process can be ensured, improving production efficiency and product quality.
