Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, an ejector sleeve comprises an ejector sleeve body 1, wherein the vertical section of the ejector sleeve body 1 is in a T shape, and the upper end and the lower end of the ejector sleeve body 1 are open and hollow, and is characterized in that a plurality of first placing grooves 11 are formed in the inner peripheral wall of the ejector sleeve body 1, the first placing grooves 11 are all arranged along the height direction of the ejector sleeve body 1, a sliding plate 3 is arranged at the first placing grooves 11 in a sliding manner on the ejector sleeve body 1, a mounting block 4 is fixed at the position, close to the central axis of the ejector sleeve body 1, of the sliding plate 3, a plurality of major arc grooves 5 are formed in the top of the mounting block 4 along the length direction of the mounting block, and rolling wheels 51 are movably arranged in the major arc grooves 5;

a plurality of reset components 2 are arranged between the sliding plate 3 and the bottom of the inner wall of the first placing groove 11.

The reset assembly 2 comprises a fixed rod 22, one end of the fixed rod 22 is fixed on one side of the sliding plate 3 far away from the mounting block 4, a sleeve 21 is fixed at the bottom of the inner wall of the first placing groove 11, one end of the sleeve 21 is fixed on one side of the inner wall of the first placing groove 11, the sleeve 21 corresponds to the position and the quantity of the first placing groove 11, one end of the fixed rod 22 extends to the inside of the corresponding sleeve 21, and an elastic part is arranged between the fixed rod 22 and the sleeve 21.

The elastic part is a spring 23, and two ends of the spring 23 are respectively fixed with the fixed rod 22 and the inner wall of the sleeve 21.

First spout 12 has all been seted up to the inner wall both sides of first standing groove 11, and the both sides of sliding plate 3 are fixed with sliding block 31, and sliding block 31 is located inside corresponding first spout 12, and sliding block 31 and first spout 12 sliding connection.
