The specific implementation mode is as follows:

referring to the figures, the cantilever type swing ball swing trainer comprises an I-shaped steel base 14, a II-shaped steel vertical frame 15, an alloy steel pipe 4 and a racket fixing device 17, wherein the I-shaped steel base 14 is provided with the II-shaped steel vertical frame 15, the II-shaped steel vertical frame 15 is vertically provided with the alloy steel pipe 4, one end of the alloy steel pipe 4 is fixedly connected with the II-shaped steel vertical frame 15 through a self-lubricating radial bearing 1 with a base, the other end of the alloy steel pipe 4 is connected with one end of an alloy steel bent pipe 5 through a radial bearing 3, the other end of the alloy steel bent pipe 5 is connected with the racket fixing device 17 through the self-lubricating radial bearing 1 with the base, the pipe walls on two sides of the alloy steel pipe 4 are respectively connected with one end of a hydraulic adjustable supporting rod 16 through a rod end joint self-lubricating bearing 2, and the other end of the hydraulic adjustable supporting rod 16 is respectively connected with a II-type steel vertical frame 15 through a self-lubricating radial bearing 1 with a base and an outer spherical surface. The adjustable hydraulic support rod 16 comprises a shell, a hydraulic support rod fixed end 6 and a hydraulic support rod movable end 7, wherein one end of the hydraulic support rod fixed end 6 is connected with the II-type steel vertical frame 15 through a self-lubricating radial bearing 1 with a base outer spherical surface, the other end of the hydraulic support rod fixed end 6 is connected with the shell, one end of the hydraulic support rod movable end 7 is connected with an alloy steel pipe 4 through a self-lubricating bearing 2 with a rod end joint, the other end of the hydraulic support rod movable end 7 stretches into the shell and is connected with the inner wall of the shell through a compression spring 9, hydraulic oil 10 is filled in the shell, and one end of the hydraulic support rod movable end 7 in the shell is provided with an oil seal 8. The shell is provided with a door-shaped oil pipe 12, two ports of the door-shaped oil pipe 12 are respectively connected with the inside of the shell, two bent parts of the door-shaped oil pipe 12 are respectively provided with an elbow 13, and the door-shaped oil pipe 12 is provided with an adjusting valve 11.

The elbow 5 can radially encircle the alloy steel pipe 4, the elbow 4 can swing around the pipe 1, and the two hydraulic supporting rods III provide certain resistance to the elbow 4. The opening of the regulating valve 11 can change the flow of hydraulic oil, and the resistance of III can be regulated. The base resistance is provided by a compression spring 9 in iii when the valve opening is at its maximum, and 9 can also serve to maintain the rest position of 4 in the quiescent state.

When in use, the handle of the racket is fixed on the racket fixing device 17 at the tail end of the alloy steel bent pipe 5 in the fixing device and is fastened through the butterfly nut.

The personnel hold the racket by hand to swing up, down, left, right, turn and the like to simulate hitting. When the alloy steel pipe moves upwards, the hydraulic adjustable supporting rods 16 are all compressed under the pressure of the alloy steel pipe 4; when doing downward motion, the hydraulic adjustable supporting rods 16 are all stretched by the tensile force of the alloy steel pipe 4; when the hydraulic adjustable supporting rod 16 moves left and right, one of the two hydraulic adjustable supporting rods is under pressure, and the other hydraulic adjustable supporting rod is under tension. Meanwhile, the alloy steel bent pipe 5 surrounds the alloy steel pipe 4 at a certain angle along with the movement. Thus, the standard amplitude and standard direction of each action can be ensured in coordination with the change of the body position.

Two ends of the hydraulic adjustable supporting rod 16 are communicated with the regulating valve 11 through a gate-shaped oil pipe 12. When the hydraulic adjustable support rod 16 is pulled, the movable end 7 of the hydraulic support rod drives the oil seal 8 to compress the compression spring 9 in the upper cavity of the shell, and simultaneously, hydraulic oil is returned to the lower cavity of the shell through the door-shaped oil pipe 12 and the regulating valve 11. When the hydraulic adjustable strut 16 is pressurized, the hydraulic oil flows in the opposite direction. Because the channel of the gate-shaped oil pipe 12 is smaller than that of the wall body, according to the throttling principle, when hydraulic oil is extruded, the resistance is very large, and a certain resistance is applied to the swinging of the alloy steel pipe 4. When the opening degree of the regulating valve 11 is reduced, since the resistance is further increased when the hydraulic oil flows, it is possible to adapt to different force demands by the regulation of the regulating valve 11 in actual use.

When the alloy steel tube is not used, the pressure spring 9 in the shell cavity is only subjected to the dead weight of the alloy steel tube 4, so that the initial position angle of the alloy steel tube can be kept, and the single end of the alloy steel tube 4 is prevented from falling to the ground.

In conclusion, the cantilever type swing ball bat trainer can not only grasp the action key through the actions of up-down, left-right, side body and side turning by holding the racket fixed at the tail end by hand, but also adjust the resistance of the instrument during action through the adjusting valve on the hydraulic adjustable supporting rod to carry out different strength training, and can be used for teaching and training, and has wide application.
