Through slot, the through slot are built-in with rubber cushion blocks.
Preferably, the diameter of the first rank bar is consistent with the diameter of second-order bar, the diameter of the second-order bar is small
In the diameter of third rank bar, the aperture of the first through hole is consistent with the diameter of the first rank bar, the aperture of second through-hole with
Length between two opposite angles of first turret head end face hexagon is consistent, and the first through hole and the second through-hole connect.
Preferably, the external screw thread on the first rank bar is matched with the internal screw thread on first through hole inner wall.
Preferably, the two sides of the rubber cushion blocks are equipped with convex block, the two sides of the through slot are equipped with up and down for convex block
Groove.
Preferably, one side of the rubber cushion blocks far from female bar axle center is cambered surface.
Preferably, the first rank bar and the first turret head are integral structures, the second-order bar, the second turret head,
Changeover portion and third rank bar are integral structures.
Beneficial effects of the present invention: the present invention changes the by adjusting the length in the first rank bar precession first through hole
The position in entire double end gear rack of three rank bars is pressed in through slot in the attachment on third rank bar to axis direction using covering
Rubber cushion blocks, to compress the sub bar in female bar, using flexible, anti-loosing effect is good.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
