[0040] Working principle: When in use, the base 8 can be fixedly installed in a designated position through the installation hole on the base 8. After the base 8 is installed, the knob 48 can be turned to drive the transmission rod to rotate. When the transmission rod rotates, the active bevel gear 47 is driven to rotate. When the active bevel gear 47 rotates, the threaded rod 41 on one side is driven through the driven bevel gear 46. The belt 411 can drive the threaded rods 41 on both sides to rotate synchronously. When the threaded rod 41 rotates, the threaded sleeve 42 is driven to move upward. When the threaded sleeve 42 moves upward, it will jointly drive the lifting plate 2 to move upward, thereby driving the shielding instrument body 3 to move upward, and the threaded sleeve 42 is also driven when it moves. The guide plate 421 will be driven to move upward on the guide rod 422, and the cover plate 7 will be driven to move upward through the fixing rod 423. When the cover plate 7 moves upward, the brush 72 will be driven to slide on the dustproof net 73 to clean the dust. When the shielding instrument body 3 is lifted to a suitable position, the knob 48 can be stopped from turning, and its angle can be adjusted during use. The worm 93 can be driven to rotate by rotating the turntable 94. When the worm 93 rotates, the worm wheel 92 is driven to rotate. When the worm wheel 92 rotates, the dustproof box 1 is driven to rotate, so that the angle of the shielding instrument body 3 can be adjusted, and the rotation can be stopped after it is adjusted to a suitable position.
