[0029] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0030] Example 1

[0031] Referring to Figure 1 and Figure 2 , the retracting assembly 1 comprises an extrusion cylinder 2, a movable support 3, a limiting rack 4, and a tooth-shaped limiting piece 5 arranged on the movable support 3; the extrusion cylinder 2 is mounted on the movable support 3, and the limiting rack 4 is arranged along the moving direction of the movable support 3; the tooth-shaped limiting piece 5 is adapted to the limiting rack 4. The tooth-shaped limiting piece 5 comprises a connecting end 501 connected to the movable support 3, and a tooth-shaped end 502 engaged with the limiting rack 4; the line between the connecting end 501 and the tooth-shaped end 502 is the supporting direction i, and the supporting direction i and the extending direction X of the limiting rack 4 form an included angle θ; when the movable support 3 needs to be fixed, the tooth-shaped end 502 is engaged with the limiting rack 4, and in this state θ < 90°. In this arrangement, when the tooth-shaped end 502 is engaged with the limiting rack 4, it is the locked state of the movable support 3, and the tooth-shaped limiting piece 5 provides an inclined supporting force for the movable support 3, making the support more stable. The limiting rack 4 is provided with two limiting racks, which are symmetrically arranged on both sides of the movable support 3; the tooth-shaped limiting piece 5 adapted to the limiting rack is provided with two tooth-shaped limiting pieces, so that the movable support 3 can be locked on both sides synchronously, ensuring that it is stable and uniform in force.

[0032] The working principle of the retracting assembly 1 provided in this embodiment is as follows: when the movable support 3 is fixed, the tooth-shaped limiting piece 5 is engaged with the limiting rack 4; when the movable support 3 moves, the tooth-shaped limiting piece 5 is disengaged from the limiting rack.

[0033] In order to facilitate the adjustment of the tooth-shaped limiting piece 5, a connecting pivot 6 is further included, and the tooth-shaped limiting piece 5 is rotatably connected to the movable support 3 through the connecting pivot 6; when the tooth-shaped limiting piece 5 is flipped around the connecting pivot to engage with the limiting rack 4, the movable support 3 can be locked in the X-axis direction; when the tooth-shaped limiting piece 5 is flipped around the connecting pivot 6 to disengage from the limiting rack 4, the movable support 3 can be released in its moving direction.

[0034] In order to enhance the restriction of the rotation of the tooth-shaped limiting member 5 in the locked state, a rotation limiting device is further provided. When the tooth-shaped end portion 502 is engaged with the limiting rack 4 in place, the rotation limiting device limits the rotation of the tooth-shaped limiting member 5, avoiding its disengagement from the limiting rack.

[0035] The connecting end portion 501 is connected with the movable support through a bolt 7, and the connecting rotating shaft 6 and the rotation limiting device are both formed on the bolt 7.
