[0028] The working principle of the utility model is as follows: when the equipment needs to be assembled during actual production and use, the bolts can be laid in advance inside the placement grid on the placement rack 306.

After the bolts in the front row of placement grids are used, the pushing component can be operated to move the tray 307 toward the discharge port 305, so that the next placement grid is moved to the level of the discharge port 305 for use, so that the tightening mechanism 1 can better take the bolts.

[0029] Furthermore, the translation assembly includes a first rotating drive member 308, a screw rod 304 and a slider 309. A slide groove adapted to the slider 309 is provided at the lower portion of the frame 2. One side of the slider 309 is slidably connected to the inside of the slide groove, and the other side of the slider 309 is connected to the tray 307.

[0033] Furthermore, the tightening mechanism 1 includes a lifting assembly and a tightening assembly. The lifting assembly is disposed on the upper portion of the frame 2, and the lifting assembly is drivingly connected to the tightening assembly.

[0034] From the above description, it can be seen that when parts need to be assembled, the parts can be placed under the tightening assembly, and then the lifting assembly is operated to make the lifting assembly drive the tightening assembly to descend to the position where the parts need to be tightened, and the bolts taken are inserted into the bolt head holes and the threaded holes one by one, and then the tightening assembly is operated to make the tightening assembly rotate the bolts into the threaded holes, thereby fixing the two parts.
