[0025] Specifically, as shown in Figure 2, a sliding adjustment plate 4 is provided at the front end of the support frame 3, and a rotating cylinder 5 is connected to the top of the sliding adjustment plate 4. The rotating cylinder 5 is used to control the rotation of the bottom screw end 14 to tighten the screw, and the sliding adjustment plate 4 controls the lifting and lowering.

[0026] Specifically, as shown in Figure 2, the bottom end of the rotating cylinder 5 is connected to a connector 6, and a connecting rod 7 is connected to the bottom end of the connector 6. The connector 6 and the connecting rod 7 are movably connected for the extension connection of the bottom end rotation.

[0027] The front end of the support frame 3 is provided with a screwing replacement component, which includes a connecting rod 7. The bottom end of the connecting rod 7 is connected to an installation rod 8. The bottom end of the installation rod 8 is provided with a screwing end 14. The screwing replacement component is used for adjusting and replacing the screwing end 14.

[0028] Specifically, as shown in Figure 3, the bottom end of the mounting rod 8 is connected to the plug block 9, and the bottom end of the plug block 9 is connected to the magnetic block 10. A rubber pad 11 is provided on the outside of the plug block 9. The magnetic block 10 facilitates the adsorption and pre-fixation of the plug block 9 after insertion, and the rubber pad 11 on the outside improves the sealing during connection.

[0029] Specifically, as shown in Figure 3, the inside of the screwing end 14 is provided with a positioning hole 15. The size of the positioning hole 15 is the same as that of the plug block 9, which can be adapted and fixed by snap-fit.

[0030] Specifically, as shown in Figure 3, a retaining ring 12 is connected to the outer side of the screwing end 14, and a positioning screw 13 is connected inside the retaining ring 12. A groove is provided on the outer side of the screwing end 14, and the retaining ring 12 is locked in the groove. Then, the positioning screw 13 passes through the screwing end 14 and is screwed onto the plug block 9 for fixation.

[0031] The inner side of the support frame 3 is provided with a replacement storage component, which includes a sliding block 18 and a folding box 19 at the top of the sliding block 18.

The bottom end is provided with a sliding structure to facilitate position adjustment. It is fixed by magnetic attraction and is easy to unfold and merge, so as to facilitate the storage and retrieval of the screwing end 14.

[0034] The specific solution is as follows: When assembling screws and workpieces placed on the processing table 2, the tightening end 14 needs to be selected according to the screw model. First, pull out the sliding block 18, then open the folding box 19, take out the appropriate tightening end 14 from inside the replacement placement plate 21, and then clip it into the bottom of the plug-in block 9. At this time, the plug-in block 9 and the positioning hole 15 inside the tightening end 14 are matched and positioned. Then, the magnetic block 10 is attracted to the inside of the tightening end 14 for pre-positioning. The contact part is set with a rubber pad 11 for stable connection. Then, the retaining ring 12 is matched and clipped together. Finally, the positioning screw 13 is screwed in for fixed position, ensuring the stability of the tightening end 14 during use and facilitating disassembly and replacement. Placing different models of folding boxes 19 also makes it easy to pull out and adjust the position, avoiding the loss of the tightening end 14 after replacement. After the tightening end 14 is selected, the equipment is started, and the power is provided by rotating the cylinder 5 and the height is adjusted by sliding the adjustment plate 4 to tighten the screws and workpieces.
