The invention has the working principle and advantages that: when the basketball three-point remote shooting auxiliary training device is used, the working process is as follows:

as shown in fig. 1, fig. 2, fig. 3 and fig. 4, two supporting seats 5 are respectively and fixedly installed on two sides of a base of a basket frame body 1 by using a fixing rod 2, then a sliding seat 33 separates a worm 34 from a worm wheel 22, a supporting rod 8 is inserted into a corresponding sleeve 17, the worm wheel 22 is rotated to drive each tooth post 20 to rotate by a gear ring 21, a bolt 19 is inserted into a ring groove 18 of the supporting rod 8, the supporting rod 8 is locked in the sleeve 17 by using the bolt 19, then the sliding seat 33 is released, the sliding seat 33 drives the worm 34 to be meshed with the worm wheel 22 under the action of a spring 35, and finally two ends of an arc limiting rod 6 are fixed on the two supporting rods 8.

As shown in fig. 2, when the height of the arc limiting rod 6 is required to be adjusted according to the pitching characteristic of each athlete, the screw 14 is rotated to drive the lifting plate 13 to move up and down through the screw transmission, so that the lifting plate 13 drives the piston plate 11 to move up and down with the pump cylinder 45 through the slide rod 12, when the piston plate 11 moves down, the piston plate 11 conveys hydraulic oil in the pump cylinder 45 into the hydraulic telescopic cylinder 7 through the liquid pipe 10, so that the hydraulic telescopic cylinder 7 stretches and drives the supporting rod 8 and the arc limiting rod 6 to lift, when the piston plate 11 moves up, the piston plate 11 generates suction force in the pump cylinder 45, and the hydraulic oil in the hydraulic telescopic cylinder 7 is conveyed into the pump cylinder 45 through the liquid pipe 10, so that the hydraulic telescopic cylinder 7 is shortened and drives the supporting rod 8 and the arc limiting rod 6 to be lowered, the arc limiting rod 6 is convenient to adjust to be at an adaptive height according to pitching characteristics of different athletes, and the practicability is improved, and the adjustment operation is simple and convenient.
