The locking pin 123 passes through a first through hole and a second through hole at the same time, and locks the relative positions of the outer tube 121 and the inner tube 122. Preferably, the number of the first through holes is multiple, the multiple first through holes are uniformly arranged along the axial direction of the outer tube 121, the cross sections of the multiple first through holes on the outer wall of the outer tube 121 on the same side are located on the same straight line, that is, the first through holes are aligned, and the distance between every two adjacent first through holes is 10mm-30 mm. The cross sections of the second through holes on the outer wall of the inner tube 122 on the same side are located on the same straight line, that is, the second through holes are arranged in alignment, and the distance between every two adjacent second through holes is 10mm-30 mm. By adjusting the relative positions of the first through hole and the second through hole, the length of the telescopic rod 12 can be adjusted by using the locking pin 123 to penetrate through the first through hole and the second through hole which are located at the same height, so that the height of the bracket is roughly adjusted.
As shown in fig. 3, the fixed seat 13 is connected to one end of the inner pipe 122 far away from the base 11, the fixed seat 13 is connected with the inner pipe 122 through the adjusting nut 14, the fixed seat 13 and the inner pipe 122 are provided with external threads matched with the adjusting nut 14, and the direction of the external threads of the fixed seat 13 is opposite to the direction of the external threads of the inner pipe 122.
