The water pump inside the water pump box 25 is fixedly connected to the water sprinkling nozzle 27 through a connecting water pipe, and the steam engine in the steam box 26 is fixedly connected to the steam nozzle 28 through a steam pipe.

[0043] The inner wall of the dividing plate 2 is provided with a driving mechanism, the outside of the driving mechanism is provided with a lamp clamping mechanism, and the upper surface of the lamp clamping mechanism is provided with a detection component.

[0044] like Figure 1-Figure 7 As shown, the driving mechanism drives the lamp clamping mechanism and controls the coordination state of the structure inside the lamp clamping mechanism. The driving mechanism includes a rotating mouth 3 opened in the middle of the dividing disk 2 to divide the above-mentioned dividing disk 2 into an upper part and a lower part. In order to control the rotation of the driving disk 34 and the detection disk 35, a driving motor 31 is fixedly sleeved on the inner wall of the lower dividing disk 2, and the main shaft end of the driving motor 31 is installed with the inner wall of the upper dividing disk 2 through a bearing. A connecting ring 32 is fixedly sleeved on the outer surface of the main shaft of the driving motor 31. In order to intermittently drive the driving disk 34 and the detection disk 35, a docking disk 33 is fixedly sleeved on the outer surface of the connecting ring 32, and the outer surface of the docking disk 33 is movably sleeved with the driving disk 34 and the detection disk 35, respectively.

[0045] In order to make the driving disk 34 and the detection disk 35 dock with the docking disk 33 in sequence, three limiting openings 36 evenly distributed in a circular array are opened on the inner surfaces of the driving disk 34 and the detection disk 35, and the inner wall of the docking disk 33 is respectively opened with a middle telescopic opening 37 and an auxiliary telescopic opening 38, and the middle telescopic opening 37 and the auxiliary telescopic opening 38 are respectively placed for the main plug-in block 39 and the auxiliary plug-in block 310, and the inner wall of the middle telescopic opening 37 is movably sleeved with the main plug-in block 39, and the inner walls of the two auxiliary telescopic openings 38 are movably sleeved with auxiliary plug-in blocks 310, in order to control the reverse movement between the main plug-in block 39 and the auxiliary plug-in block 310, a wire groove 311 is opened between the two auxiliary telescopic openings 38 and the middle telescopic opening 37, and a pressure spring 312 and a traction rope 313 are respectively fixedly connected at one end of the auxiliary plug-in block 310, and the free end of the pressure spring 312 is connected to the auxiliary telescopic opening The inner wall of one end of 38 is fixedly connected, and the free end of the traction rope 313 is fixedly connected to the surface of one end of the main plug-in block 39, so that the main plug-in block 39 and the two auxiliary plug-in blocks 310 are movably plugged into the inner walls of the three limit openings 36 respectively. When the main plug-in block 39 moves to the limit opening 36 in the driving disk 34, the traction rope 313 will be pulled. Since the pulling force is greater than the elastic force of the pressure spring 312, the auxiliary plug-in block 310 is pulled out from the limit opening 36 on the detection disk 35, so that the docking disk 33 and the driving disk 34 are docked. After the main plug-in block 39 moves to the middle telescopic opening 37, the traction rope 313 loses the pulling force, and the pressure spring 312 squeezes the auxiliary plug-in block 310, so that the auxiliary plug-in block 310 is inserted into the limit opening 36 on the detection disk 35, so that the docking disk 33 and the detection disk 35 are docked.
