Thus, two guide rails are arranged on the first reinforcing rib 500, and the running stability of the guide rails is further improved by increasing the number of the guide rails; further, the lifting stability of the smoke collecting box 200 of the lifting smoke machine 10 is improved, and the smoke collecting box 200 can be prevented from shaking relative to the fan box 100 when the fan 120 works. In addition, there will typically be an assembly gap between the first sliding connector 321 and the first rail 311 and between the second sliding connector 322 and the second rail 312. The inventors have found that the first rail 311 and the second rail 312 are of the same type, such that when they are placed in the same posture, they are substantially in line with possible shaking directions in the horizontal direction between the respective sliding connectors. By mounting the first rail 311 and the second rail 312 on the first sidewall 510 and the second sidewall 520, respectively, which are located at different planes, a possible shaking direction between the rails and their corresponding sliding connectors becomes different, and the two sliding connectors are reduced in the degree of freedom of being movable with respect to the respective rails under the action of the reinforcing ribs, so that the smoke collecting case 200 can be prevented from shaking with respect to the fan case 100.
