The ends of the bolts 8 fit with the inner walls of the grooves 9, and the ends of the bolts 8 are against the grooves 9 to fix the frame 7, thereby fixing the transparent plate 6. The height of the transparent plate 6 can be adjusted by loosening the bolts 8 to adapt to the use of users of different heights. After adjusting to a suitable height, the bolts 8 are tightened so that the ends of the bolts 8 fit closely with the inner walls of the grooves 9. An L-shaped handle 11 is fixed on the side of the square cover 5 away from the bracket 2, and wiping strips 15 are fixed on the opposite sides of the inner wall of the square cover 5. The opposite surfaces of the two wiping strips 15 are respectively slidably connected to the two sides of the transparent plate 6. During the up and down movement of the transparent plate 6, the wiping strips 15 fixed in the square cover 5 are used to wipe the two sides of the transparent plate 6 to make the transparent plate 6 cleaner and tidier.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, the connecting frame 4 includes two connecting blocks 41 fixed on the side of the bracket 2, and a connecting plate 42 is fixed to the side of the connecting block 41. The side of the connecting plate 42 away from the connecting block 41 is fixedly connected to the side of the square cover 5. The connecting plate 42 is used to connect and fix the connecting block 41 and the square cover 5, so as to fix the square cover 5 to the side position of the base 1.

[0029] like Figure 2 As shown, in this embodiment, a square bar 43 is fixed between the two connecting blocks 41, and the square bar 43 is fixed on the top of the bracket 2. The square bar 43 is used to increase the contact area between the connecting block 41 and the bracket 2, thereby improving the connection strength between the connecting block 41 and the bracket 2.

[0030] like Figure 2 As shown, in this embodiment, a round rod 44 is fixed between the two connecting plates 42 , and the round rod 44 is used to connect the two connecting plates 42 to improve the structural strength of the connecting plates 42 .

[0031] like Figure 1 and Figure 2As shown, in this embodiment, a hollow groove is opened on the side of the connecting plate 42, and the hollow groove is used to reduce the weight of the connecting plate 42, so that the rotation of the connecting plate 42 is easier.

[0032] like Figure 2 As shown, in this embodiment, an arc angle iron 13 is fixed to the bottom of the connecting plate 42, and the inner wall of the arc angle iron 13 is slidingly connected to the top and the arc surface 16 of the base 1 respectively. When the connecting frame 4 rotates, the arc angle iron 13 is driven to rotate along the top and the arc surface 16 of the base 1. The arc angle iron 13 is used to support the rotation of the connecting frame 4, so that the horizontal rotation of the transparent plate 6 and the fog cannon 3 is smoother and smoother.

[0033] like Figure 1 As shown, in this embodiment, the top of the L-shaped handle 11 is rotatably connected to a round sleeve 12, and anti-slip grooves are provided on the circumferential surface of the round sleeve 12. By holding the round sleeve 12, the fog cannon 3 can be driven to rotate through the L-shaped handle 11. The round sleeve 12 can rotate on the L-shaped handle 11, thereby reducing the friction between the L-shaped handle 11 and the hand, and the design of the anti-slip grooves makes the holding of the round sleeve 12 more stable and reliable.

[0034] like Figure 3 As shown, in this embodiment, the end of the bolt 8 is hemispherical, and the shape of the inner wall of the groove 9 is adapted to the shape of the end of the bolt 8. The hemispherical shape increases the contact area between the bolt 8 and the inner wall of the groove 9, thereby making the fixation of the frame 7 and the transparent plate 6 more stable and reliable.

[0035] Working principle: when the wind blows from the dust generating position toward the user of the fog cannon 3, the transparent plate 6 is used to block the dust and water mist, preventing the water mist and dust from blowing to the user of the fog cannon 3, thereby protecting the user. When it is necessary to adjust the height of the transparent plate 6, the bolt 8 is loosened to separate the end of the bolt 8 from the inner wall of the groove 9. After separation, the transparent plate 6 can be moved upward or downward. The transparent plate 6 drives the frame 7 to move along the inner wall of the square cover 5 and the guide rail 10. The height of the transparent plate 6 is adjusted to adapt to the use of users of different heights. After adjusting to the appropriate height, the bolt 8 is tightened to make the end of the bolt 8 fit closely with the inner wall of the groove 9, so as to fix the height of the frame 7 and thus fix the height of the transparent plate 6.

[0036] When the transparent plate 6 moves up and down, the wiping strip 15 fixed in the square cover 5 is used to wipe both sides of the transparent plate 6 to make the transparent plate 6 cleaner and tidier.

[0037] When adjusting the horizontal angle of the fog cannon 3, the square cover 5 can be rotated by holding the round sleeve 12 on the L-shaped handle 11, so that the square cover 5 drives the bracket 2 to rotate around the rotating shaft 14 through the connecting frame 4, and the horizontal angle of the fog cannon 3 is adjusted to adapt to different usage requirements. When the connecting frame 4 rotates, the arc angle iron 13 is driven to rotate along the top and arc surface 16 of the base 1. The arc angle iron 13 is used to support the rotation of the connecting frame 4, so that the horizontal rotation of the transparent plate 6 and the fog cannon 3 is smoother and smoother.

[0038] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
