[0022] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0023] As shown in the figure, the utility model discloses a fast lifting and switching mechanism, including a fixed component 1, a lifting component 2 and a support component 3. The fixed component 1 includes a support base plate 11 and a guide cylinder 12. The guide cylinder 12 is arranged in the middle of the support base plate 11. A through hole 13 is arranged in the middle of the guide cylinder 12. A guide groove 14 is arranged on the outer wall of the guide cylinder 12. The outer diameter of the lifting component 2 is smaller than the inner diameter of the guide cylinder 12. A horizontal clamping rod 21 is arranged on the outer wall of the lifting component 2. The clamping rod 21 is located at the guide groove 14. The support component 3 is arranged on the top of the lifting component 2. The fixed component 1 is fixed in the workshop. When it is necessary to switch the subframe of another station, the clamping rod 21 is manually pushed to move along the guide groove 14 to drive the support component to lift and lower. The support component 3 of the utility model has 2 positions.
