In the use process, firstly, the product is installed according to the height problem of a user, and the installation block 5 is arranged on one rail of the quadrangular fence and is perpendicular to the baffle 13.

Wear to be equipped with adjusting bolt in the installation piece 5, adjusting bolt aims at the hole on the wall, and adjusting bolt twists the hole to the wall, twists to close, has just accomplished the butt joint after twisting to close, because the hole on the wall has the height to divide, consequently can fix installing support 1 on suitable height.

And the mounting block 5 and the baffle 13 are vertically arranged, so that the floor area of the mounting bracket 1 is greatly reduced, the tennis ball 4 can be hit in the hitting process, the end part of the connecting rod 3 is fixedly connected with the tennis ball 4 through a spring, one part of the spring is clamped into the tennis ball 4, and the other part of the spring is welded with the connecting rod 3.

The tennis ball 4 receives the correct force, as shown in fig. 6, the swing direction is between 0 degree and 45 degrees, so as to hit a parabola, which is the force that can make the connecting rod 3 rotate counterclockwise around the hinge shaft 9, which is the normal hitting angle of the tennis ball, and at this time, the hinge shaft 9 is located right above the hinge hole 7, and only rotates, and cannot move.

However, many people do not rotate about the hinge axis 9 if they do not throw a parabola while hitting the tennis ball 4, because they are also novice during practice.

First, as shown in fig. 5, when the tennis ball 4 is hit from the side, the tennis ball 4 with the connecting rod 3 will be deflected, the deflected connecting rod 3 will be abutted against the upright post 2, and an elastic sponge pad is arranged between the connecting rod 3 and the upright post 2 to reduce looseness and noise, at this time, the user does not hit a parabola to be exercised because the connecting rod 3 cannot generate a rotating force.
