The upper end surface of the conveyor belt 303 is on the same horizontal plane as the placement groove 4. By providing the feeding component 300, the nut can be effectively automatically fed. When it is necessary to automatically feed the nut, the nut is placed on the conveyor belt 303, and then the driving motor two 304 is started to drive the conveyor belt 303 to rotate. The conveyor belt 303 drives the nut to be conveyed into the placement groove 4, so as to automatically feed the nut.

[0032] During operation, first place the nut on the conveyor belt 303, then start the second driving motor 304 to drive the conveyor belt 303 to rotate. The conveyor belt 303 drives the nut to be conveyed into the placement groove 4. Then start the driving motor 2 to drive the turntable 3 to rotate. The turntable 3 drives the nut in the placement groove 4 to rotate to one side of the movable groove 205. Then start the electric push rod 201 to drive the V-shaped abutting block 203 to squeeze the nut in the placement groove 4, so as to squeeze and fix the nut in the placement groove 4. Then use the tapping mechanism to tap the nut. After tapping is completed, the driving motor 2 drives the turntable 3 to continue rotating to directly above the blanking groove 113. Then start the first driving motor 101 to drive the rotating block 102 to rotate. While the rotating block 102 is rotating, the second sliding rod 111 slides in the rotating block 102 under the elastic action of the spring 112. Then through the mutual cooperation between the guide rod 104, the sleeve 105, the first sliding rod 106, the sliding block 107 and the support rod 108, the insertion rod 109 is driven to insert into the nut hole, and then move towards the blanking groove 113.
