A support column 2 is slidably arranged up and down inside the lifting groove 32. A smoke generator 4 is fixedly installed at the top of the upper support column 2. A nozzle 5 is communicated with the side wall of the smoke generator 4. A grip 1 is arranged at the bottom wall of the lower support column 2. And a bidirectional lead screw 31 is rotationally connected inside the lifting sleeve 3 through a driving assembly. The bidirectional lead screw 31 is threadedly connected with the support column 2. The driving assembly includes an installation groove 33 opened inside the lifting sleeve 3. A driving motor 34 is fixedly installed inside the installation groove 33. A driving gear 35 is fixedly installed on the output shaft of the driving motor 34. A driven gear 36 meshing with the driving gear 35 is fixedly installed on the outside of the bidirectional lead screw 31.

[0021] Here, by starting the driving motor 34, the driving motor 34 can drive the driving gear 35 to rotate. The driving gear 35 meshes with the driven gear 36 to drive the bidirectional lead screw 31 to rotate. The bidirectional lead screw 31 can push the upper and lower support columns 2 to approach or move away from each other, so that the height of the smoke generator 4 and the nozzle 5 can be adjusted according to requirements, improving the convenience of height adjustment of the device.

[0022] Refer to Figure 2 and Figure 3 , a limit sliding groove 321 communicated with the lifting groove 32 is opened inside the lifting sleeve 3. A limit slider 23 is slidably connected inside the limit sliding groove 321. The limit slider 23 is fixedly connected with the support column 2.

[0023] Here, by providing the limit sliding groove 321 and the limit slider 23, when the bidirectional lead screw 31 rotates, the support column 2 can be pushed to move up and down without rotating along with the bidirectional lead screw 31.

[0024] Refer to Figure 3, a limiting groove 11 is formed at the top of the grip 1, a limiting post 21 is rotatably arranged inside the limiting groove 11, the limiting post 21 is fixedly connected to the lower support post 2, and a locking bolt 12 for restricting the rotation of the limiting post 21 is threadedly connected to the side wall of the grip 1.

[0025] By loosening the locking bolt 12 here, the limiting post 21 can rotate inside the limiting groove 11, so that the angle of the nozzle 5 can be adjusted, improving the practicability of the device.

[0026] Refer to Figure 3 , a plurality of anti-slip grooves are formed in the circumferential direction of the grip 1.
