detailed description:

The present invention will be further described below in conjunction with the accompanying drawings. As shown in FIGS. The upper automatic screwdriver mounting frame 3, the upper screw positioning nozzle 2 are located at the bottom of the shell 1, the top of the shell 1 is provided with a screw storage bin 11, and the top of the screw storage bin 11 is provided with a top cover 16. The inside of the shell 1 is provided with an input slideway 4, a spiral slideway 5 for turning the direction of the screw, and an output slideway 6. The entrance of the input slideway 4 is connected to the screw storage bin 11, and the two ends of the spiral slideway 5 are respectively connected to the input slideway. The outlet of 4 is connected with the inlet of output slideway 6, and the outlet of output slideway 6 communicates with upper screw positioning nozzle 2.

The helix angle of the spiral slideway 5 is 180 degrees, so that the screw just changes direction by 180 degrees after passing through the spiral slideway 5 . A steering column 7 is arranged between the input slideway 4 and the output slideway 6 , and the spiral slideway 5 is arranged on the outer circumferential surface of the steering column 7 . The output slideway 6 is composed of two sections of inclined slideway 61 which are mutually angled.

Two parallel adjustment splints 8 are arranged in the screw storage bin 11, and the two adjustment splints 8 are connected by adjustment screws 9. The top of the adjustment splint 8 is provided with a slope 81 corresponding to the entrance of the input slideway 4, and through the adjustment screw 9 The distance between the two adjustable splints 8 can be adjusted, and screws between 2.4mm and 3.0mm can be used. The housing 1 is slidably connected with a lifting slide 12, and the installation frame 3 and the two adjusting splints 8 are fixedly connected to the lifting slide 12. When the lifting slide 12 slides down, it drives the adjusting splint 8 to slide downward. At this time, the screw storage bin 11 The screw will automatically slide onto the adjusting splint 8, and the threaded end of the screw will enter between the two adjusting splints 8. And the nut is stuck on the top of the adjustment splint 8. When the lifting slide 12 drives the adjustment splint 8 to reset upward, the screw sandwiched between the two adjustment splints 8 will slide into the input slideway 4 along the slope 81 of the adjustment splint 8. middle.
