The bolt enters the groove 5-3 and moves linearly along the gap between the positioning plate 5-4 and the limit rod 5-8. When the conveyor belt 5-2 moves to the tapping position, it stops. Then the telescopic cylinder 4-2 is started to push the clamping block 4-5, and the bolt material is pushed into another clamping block 4-5 and clamped. The round rod 5-7 moves in the cross plate 4-3 and shrinks in accordance with the change of position to position the bolt material in the tapping position. Then the lifting seat 2 and the tapping motor 3 are started to perform tapping. After completion, the telescopic cylinder 4-2 is reset, and the spring 4-6 pushes the clamping block 4-5 to reset the bolt after tapping is completed. Start the conveyor belt 5-2 to convey the bolt again, and after moving to the other side, it falls into the collection box 6-4 through the inclined mouth 6-1 and the sliding plate 6-2, and the collection box 6-4 can be taken away.
