When in use, the driving gear 15 can be driven to rotate through the external structure, thereby driving the movable rod 16 to move, so that it can shrink toward the inside of the limit block 9 with the positioning protrusion 18, so that the positioning protrusion 18 is separated from the positioning hole 6, thereby releasing the positioning state, so as to facilitate pushing the adjustment seat 7 and the frame 21 to slide inside the adjustment groove 3, thereby achieving the purpose of adjusting the position of the frame 21 and realizing the adjustment of the support position of the pipeline.

[0027] In a further technical solution, a second bevel gear 14 is fixedly sleeved on the top end of the transmission shaft 13, a connecting rod 11 is arranged on the top end of one side of the outer side of the adjustment seat 7, the connecting rod 11 is movably connected to the adjustment seat 7 through a bearing, a knob 10 is installed on the outer end of the connecting rod 11, and a first bevel gear 12 is arranged on the other end of the connecting rod 11, the first bevel gear 12 is meshingly connected with the second bevel gear 14, by rotating the knob 10, under the transmission of the connecting rod 11, the first bevel gear 12 and the second bevel gear 14, the power is transmitted to the driving gear 15 through the transmission shaft 13, so as to achieve the purpose of driving the movable rod 16 to move.
