[0024] In this embodiment, a reinforcement ring 3 is fixedly connected to the upper surface of the base 1, and the inner wall of the reinforcement ring 3 is fixedly connected to the outer surface of the column 2, which strengthens the firmness of the column 2, avoids the shaking of the device during use, and prolongs the service life of the device. A sealing ring 16 is fixedly connected to the upper surface of the column 2, and the inner ring of the sealing ring 16 contacts the outer surface of the threaded tube 9 to avoid dust in the air from entering the device and ensure the normal operation of the device.
