detailed description

Please refer to FIG. 1 to FIG. 10, a middle beam combination with an improved assembly method includes a barrel 3, a fork 4, a spiral 2 and a jacket 1 which are coaxially inserted from the inside to the outside. A protrusion 30 is provided on the outer side wall of the bucket 3, and a hollow guide groove 40 matching the protrusion 30 is provided on the fork 4 in the axial direction, and is provided on the inner wall peripheral surface of the spiral 2 There is a spiral guide groove 20 that rises spirally in the axial direction. The protrusion 30 can pass through the hollow guide groove 40 of the fork 4 and be slid into the spiral guide groove 20 of the spiral 2. An elastic piece 41 is provided on the outer wall of the fork 4, and the elastic piece 41 is in contact with the inner wall of the spiral 2. An axially arranged rotation preventing mechanism and a circumferentially arranged anti-falling mechanism are provided between the spiral 2 and the outer casing 1.
