Embodiment
1-2 below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this reality
Do not limited with new protection domain by embodiment.It is common based on the embodiment in the utility model, this area
The every other embodiment that technical staff is obtained on the premise of creative work is not made, belong to the utility model guarantor
The scope of shield.
A kind of tennis auxiliary practice device provided by the utility model, as shown in figure 1, including：Base 1, on the base 1
Provided with montant 2, limited post 3 and support column 4, the montant 2 is hinged on the base 1, the limited post 3 and support column 4
In the front and rear sides of the montant 2, and the limited post 3 and the montant 2 are adjacent, and the limited post 3 is provided with magnet, and institute
The side for stating the adjacent limited post 3 of montant 2 is provided with groove 3-1, and the top surface of the support column 4 is inclined-plane, the inclined-plane court
To the direction of the montant 2, the inclined-plane is provided with supporting plate 4-2, the support provided with spring 4-1, the spring 4-1
Plate 4-2 is parallel with the inclined-plane, and the upper end of the montant 2 is provided with return device 5, and the return device 5 is provided with tennis resetting means
6, the tennis resetting means 6 is provided with support tube 7, and the outer end of the support tube 7 is provided with tennis 8.
Further, as shown in Fig. 2 the tennis resetting means 6 is spring, one end of the spring and return device 5 connect
Connect, the other end connects through the support tube 7 with tennis.When impacting tennis 8, tennis 8 is launched, under the action of the spring net
Ball 8 can keep in the center rapidly, allow practitioner to continue to practise.
Further, the tennis resetting means 6 includes sutomatic winding machine, and the winding line of the sutomatic winding machine passes through institute
State support tube 7 to connect with tennis, sutomatic winding machine connects with power supply.When impacting tennis 8, the throwing of tennis 8 can reach in the air
More preferable visual effect, improves the interest of practitioner, and tennis can be retracted original position, continue to practise by winding line.
Further, the montant 2 is expansion link, can with adjusting means height, with the people suitable for different heights or
Different breaktests uses.
During using tennis auxiliary practice device of the present utility model, tennis 8 is arranged on one end of support tube 7, can be selected
Absorption or the mode of binding.Support tube 7 and tennis resetting means 6 connect, and tennis resetting means 6 and return device 5 connect, and beat
