[0029] The surface of the sliding baffle 108 is slidably connected with the inner wall of the telescopic arm 105, the surface of the rotating screw 103 is threadedly connected with the inner wall of the telescopic arm 105, the number of support sleeves 102 is three, and the support sleeves 102 are symmetrically distributed at the center of the protective shell 101.

[0030] The driving mechanism 2 comprises a motor 201, the output end of the motor 201 is fixedly connected with a rotating shaft 202, the surface of the rotating shaft 202 is fixedly connected with a driving bevel gear 203, the surface of the motor 201 is fixedly connected with a motor sleeve 204, the lower end of the motor sleeve 204 is fixedly connected with a mounting frame 205, the design that the motor 201 is used to drive the driving bevel gear 203 to rotate realizes the purpose that the surrounding driven bevel gear 104 is conveniently driven to rotate, provides power for the subsequent operation of the device, and makes the use of the device more convenient.
