Piece is equipped with the ring-type of through-hole centered on the retaining ring, and the retaining ring is set on the intermediate plate, and the retaining ring is located at two
Position is bent downward between the intermediate plate of side, and is squeezed the intermediate plate and curved inwardly and generate deformation, further includes pressing push rod, the pressing
Push rod is threaded through the upper turbine center, and the pressing push rod lower end two sides topstick is in the retaining ring.
Further, further include be arranged in the head upper by gland, it is described press gland middle inside be equipped with it is downwardly convex
Out and the protrusion for pressing push rod can be pressed.
Further, described to be formed by gland by stamped metal on chip, the protrusion is described to press gland by being stamped and formed out downwards
Side is equipped with the fixinig plate being plugged on head.
It deformation can be pushed easily when pushing by gland as preferably ensuring that, it is described to press gland and fixinig plate junction two sides
Equipped with fluting.
Preferably, further impetus is played to vehicle needle when providing stable clamping and pressing to vehicle needle, it is described to press
Press the accommodation groove being equipped in the middle part of push rod for vehicle needle merging.
Further, the pressing push rod lower section is equipped with the lead-over groove passed through when pressing down on for the intermediate plate.
Further, the chamfering that guide car needle enters accommodation groove is equipped between the lead-over groove and accommodation groove.
Preferably, the clip number be every side it is each at least one, intermediate plate carries out stable clamping to vehicle needle.
Further, limiting slot is equipped with the intermediate plate contact position in the retaining ring.
The beneficial effects of the present invention are: joined using at least two longitudinally disposed intermediate plates with the retaining ring being laterally arranged
Dynamic cooperation clamps vehicle needle, intermediate plate bite to vehicle needle set have it is upward cut power, effectively prevent vehicle needle to loosen, laterally set
The retaining ring set provides lateral fastening force to intermediate plate and provides enough clamping forces, while pressing push rod downward push and make retaining ring
Pine pushes vehicle needle and plays auxiliary disassembly to vehicle needle, so that pressing rear car needle falls off conveniently.
