A retractable limit block 40 is arranged on the processing platform 10 , and the limit block 40 is arranged in a limit oil cylinder 41 .

Both sides of the drill bit 20 are provided with pressing heads 51 that can move downward.

A clamping mechanism is provided under the drill bit 20 , and the clamping mechanism includes clamping heads 52 respectively arranged on both sides of the processing platform 10 and an air cylinder driving the clamping heads 52 to move toward the processing platform 10 .

The two sides of the feed port 11 of the processing platform 10 are respectively symmetrically provided with guide blocks 53 , and the side of the guide block 53 facing the feed port 11 is provided with an outwardly expanding slope.

A material rack 80 is provided on the other side of the material outlet 12 of the processing platform 10 relative to the material return cylinder for receiving the processed leaf spring 60 .

The outwardly expanded slope of the guide block 53 facilitates the entry of the leaf spring 60 from the feeding port 11 of the processing platform 10 .

The pull block 36 is used to control the pull block 33, and the second bump 361 provided on the pull block 36 is used to cooperate with the first bump 331 of the pull block 33.
