Carry groove (24), the support of bearing (25).
The built-in tennis of cone bucket (23), both sides are connected with cone bucket bracing frame (2), the tennis below cone bucket bracing frame (2) with both sides
Bearing groove support (6) connects, and connects tennis bearing groove by fastening bolt (20) in the upper part of tennis bearing groove support (6)
(24), its internal undertaking tennis (21).In the front end of tennis bearing groove (24), by bolt and nut securing member (4) closure
Modification plate (3).In the lower section of tennis bearing groove support (6), it is connected on base plate (7) by fastening bolt (18).Hold in tennis
The rear position for carrying groove (24) is hammer (22), and hammer (22) rear is once connected with tooth bar (1), guide rod (14), and three is one
Body formula structure.In guide rod (14) this section, spring (11) is installed with, guide rod (14) is fixed on the guide bar support (15) of lower section.
Stator on guide bar support (15) can make guide rod (14) reciprocatingly slide.The lower section of guide bar support (15) passes through fastening bolt (9)
Installed, be fastened on following base plate (7).In tooth bar (1) this section, there is gear (12) to be engaged with transmission, with tooth
It is turbine (5) that wheel (12) is coaxial mounted, and the two public same shaft part is fixed by the support of bearing (25) of both sides, under
Side is fixed on base plate (7) by fastening bolt.What is engaged with turbine (5) is worm screw (13), worm screw (13) and motor
(17) main shaft connection.Motor (17) is fixed on following base plate (7) by fastening bolt (16).After on the base plate (7)
Orientation is put, and equipped with handrail (10), in the lower section of base plate (7), equipped with roller (8), in the front of roller (8), is connected with base plate (7)
Be cushion block (19).
The beneficial effects of the utility model：The design of roller type can play a part of conveniently moving, and overall structure is simple, system
Make low cost, easily operate with.The drive mechanism of the turbine and worm of addition can greatly improve moment of torsion, make to overcome spring force to do work
More easily, while the selection to motor may be selected the less model of power, cost of manufacture is saved, exports can motor
Little moment of torsion can just complete serve a ball ability.
Description of the drawings
Fig. 1 is this utility model product overall structure diagram.
Fig. 2 is this utility model product overall structure diagram.
Specific embodiment
Present embodiment is described further according to Fig. 1, Fig. 2.Move can whole device by promoting handrail (10)
It is dynamic to be placed in region to be used.During service, the built-in netful ball of cone bucket (23), by the gravity of itself, tennis will drop down onto tennis and hold
Carry in groove (24), the pivot angle of plate (3) is changed so as to adjust the elevation angle of tennis service by adjusting direction.During service, motor
(17) rotate, main shaft drives worm screw (13) rotation, worm screw (13) to drive turbine (5) to rotate again, due to gear (12) and turbine (5)
