[0026] The working assembly includes a rotating wheel 2. The bottom of the machine body 1 is provided with the rotating wheel 2. A rotating shaft 3 is fixedly connected to one side of the rotating wheel 2. The outer wall of the rotating shaft 3 is rotatably connected with a connecting plate 4.

[0027] The clamping assembly includes a first fixed plate 5, the outer wall of the rotating shaft 3 is spirally connected to the first fixed plate 5, one end of the first fixed plate 5 is fixedly connected to a first clamping piece 6, the outer wall of the rotating shaft 3 is spirally connected to a second fixed plate 7, one end of the second fixed plate 7 is fixedly connected to a second clamping piece 8, the inner wall of the second clamping piece 8 is provided with a support column 9, and the bottom of the connecting plate 4 is fixedly connected to a base plate 10.

[0028] Among them, Figure 3 As shown, the first fixing plate 5 is provided with a threaded groove which matches the rotating shaft 3. The first fixing plate 5 forms a spiral structure with the rotating shaft 3 through the rotating wheel 2, which is conducive to driving the first clamping plate 6 to move by rotating the rotating shaft 3, thereby clamping the support column 9 and fixing the connecting plate 4 at the bottom of the body 1 for easy installation.

[0029] Among them, Figure 3 As shown, four groups of the first fixing plate 5, the first clamping plate 6, the second fixing plate 7, the second clamping plate 8 and the supporting column 9 are arranged, and the positional relationship of the four groups of the first fixing plate 5, the first clamping plate 6, the second fixing plate 7, the second clamping plate 8 and the supporting column 9 is symmetrically distributed about the midpoint of the fuselage 1, which is beneficial to ensure the stability of the fixing of the connecting plate 4 and prevent it from falling off during flight.

[0030] Example 2

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, the outer wall of the base plate 10 is fixedly connected with a hollow block 11, the inner wall of the hollow block 11 is fixedly connected with a spring 12, one end of the spring 12 is fixedly connected with a sliding block 13, one end of the sliding block 13 is fixedly connected with a protective shell 14, the inner wall of the protective shell 14 is fixedly connected with a sliding column 15, the outer wall of the body 1 is provided with an arm 16, one end of the arm 16 is fixedly connected with a spiral blade 17.
