In main body 81, the angle of footing 82 and center bearing bracket 10 is 100 degree, is preferred support angle.Anti-skidding cushion block 83 is fixedly arranged on bottom
The bottom of foot 82 keeps the stability of pedestal 80 stronger for enhancing the frictional force between footing 82 and ground.
Further, refering to fig. 10, footing 82 is articulated in base body 81 by screw, for footing 82 in expansion and
Switch between the state folded.When footing 82 turns to be bonded parallel with center bearing bracket 10 with center bearing bracket 10, footing 82 is
Folded state.
The working principle of tennis training machine is described in detail below: first stablizing pedestal 80 expansion of footing 82 and stands
In in the first T-type card slot 111 for being plugged on appropriate height on ground, by cross bar 20, by bracket outer tube 11 be adjusted to be suitble to height；
Sportsman strikes simulation tennis 70, and simulation tennis 70, swing arm 50, swing seat 40 are together around the central axis of cross bar 20
Rotation is then realized that rebound resets by the screen resilience of torsion spring member 30, the backhaul limit that limit film 22 resets it, fortune
Moving member can carry out repeatedly breaktest repeatedly.
The folding process of tennis training machine is described in detail below: refering to Fig. 9-Figure 10, by swing arm 50 around swing
Seat 40 rotates, and makes the fitting parallel with cross bar 20 of swing arm 50, by cross bar 20 and the swing arm 50 folded together from bracket outer tube
It removes on 11, two cross bars 20 is fastened on the second T-type card slot 114 by the fastener 21 of cross bar 20；Trip spring Button Block 13,
The height of bracket outer tube 11 is adjusted to it is minimum, make its with bracket inner tube 12 completely set merge it is fixed with spring Button Block 13；By footing
82 rotate around pedestal 80, make the fitting parallel with center bearing bracket 10 of footing 82.So far, then the entire mistake of tennis training machine is completed
Journey；Conversely, being then the expansion process of tennis training machine.
By being elaborated to above-described embodiment, it will be understood that the utility model can allow trainer in the short time
Interior multiplicating strikes the same tennis, does not need other and carries out cooperation service to white silk personnel and pick up ball, when saving a large amount of
Between and physical strength；And the position that tennis resets every time is identical, trainer is not required to move repeatedly to strike；It can be to tennis
Height is adjusted, and so that tennis training machine is adapted to the crowd that uses of different heights, and can be to a variety of impact height
Technical movements are trained, and expand training area, enhance training effect.In addition, tennis training machine can carry out significantly
Folding, fold fold after small in size, use easy to carry, allow trainer in a variety of places such as office, family
Parlor, park etc. are practiced whenever and wherever possible, very easy to use.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
