[0040] When the height of the positioning pipe 2 needs to be adjusted, the first motor 13 needs to be started, the reciprocating screw rod 14 is driven to rotate by the output shaft of the first motor 13, the moving block 16 is driven to move by the reciprocating screw rod 14, the positioning pipe 2 and the trumpet pipe 23 are driven to move by the moving block 16, until the appropriate position is reached, wherein the moving block 16 slides on the guide rod 15 during the movement process, the guide rod 15 limits the movement of the moving block 16 in the vertical direction. During the movement of the positioning pipe 2, the movement distance of the positioning pipe 2 is monitored by the laser range finder 22, when the specified position is reached, the signal is transmitted to the system, the first motor 13 is controlled to be turned off by the system, so that the intelligent lifting effect is realized.
