Description
Technical field
The utility model relates to a kind of tennis ball hitting point trainer, belongs to tennis training device.
Background technology
Beginner is when training tennis ball hitting point, need an auxiliary by tennis from certain altitude throwing, striker until tennis land upspring after bat, auxiliary is after toss, need fast arm to be regained, otherwise likely got to by the racket of striker, there is certain danger.
Utility model content
The utility model, for the problem in background technology, proposes a kind of tennis ball hitting point trainer.
The utility model, for overcoming the above problems, adopts following technical scheme:
A kind of tennis ball hitting point trainer, comprises base plate, column, hinge, iron, hand-tight screw, ball holder, support, electromagnet and spring; Described column lower end is connected with base plate; Described iron one end is flexibly connected with column by hinge, and the iron other end is provided with screwed hole; Described hand-tight screw screws in screwed hole and is connected with ball holder; Described spring one end is connected with iron, and the spring other end is connected with column; Described electromagnet is fixed on column side by support; Described base plate is provided with switch; Described electromagnet is connected with power supply by the normally-closed contact of switch.
Preferably, described switch adopts floor push.
As scheme optimization, described iron is also provided with handle.
Technique effect:

Detailed description of the invention
Below in conjunction with accompanying drawing, introduction is in further detail done to the technical solution of the utility model:
Structure of the present utility model as shown in Figure 1, comprises base plate 1, column 2, hinge 3, iron 4, hand-tight screw 6, ball holder 7, support 8, electromagnet 9 and spring 10; Described column 2 lower end is connected with base plate 1; Described iron 4 one end is flexibly connected with column 2 by hinge 3, and iron 4 other end is provided with screwed hole 5; Described hand-tight screw 6 screws in screwed hole 5 and is connected with ball holder 7; Described spring 10 one end is connected with iron 4, and spring 10 other end is connected with column 2; Described electromagnet 9 is fixed on column 2 side by support 8; Described base plate 1 is provided with switch 11; Described electromagnet 9 is connected with power supply by the normally-closed contact of switch 11.
Described switch 11 adopts floor push, is convenient to user and is controlled electromagnet 9 power on/off by foot-operated mode.
Described iron 4 is also provided with handle 12, facilitates user to pull iron 4 to rotate along hinge 3.
Described electromagnet 9 adopts the triumphant peaceful automatic control device factory in Nanjing model to be the sucked type electromagnet of PCT340, supporting plate can be held when sucker electromagnet is energized.The height in electromagnet 9 adhesive face is highly identical with hinge 3.
Described floor push adopts Zhejiang Tian get Electrical Appliances Co., Ltd model to be the floor push of TFS-201, for controlling electromagnet 9 power on/off.
Described ball holder 7 is the block rubber of end face band arc groove, for being held by tennis.
During training, user first pulls iron 4 to rotate along hinge 3, until iron 4 contacts with electromagnet 9, because floor push is not operated, the normally-closed contact of floor push closes, and electromagnet 9 and power supply are connected and held by iron 4, thus make iron 4 maintenance level, now, spring 10 is in extended state, and tennis 13 can be placed on (as shown in Figure 2) in ball holder 7 by trainer.Afterwards, trainer only need step on floor push, disconnect to make the normally-closed contact of floor push, electromagnet 9 and power supply disconnect and lose suction, iron 4 and ball holder 7 go back to rapidly column 2 (as shown in Figure 3) under the pulling force effect of spring 10, rebound after tennis 13 freely falling bodies to base plate 1, bat for trainer.
