Embodiment:

As shown in attached drawing 1 to attached drawing 8:

The present invention provides a kind of auxiliary device of double-purpose adjustable type tennis service training, includes: aggravating pedestal 1, function Slot 2, thread bush 3 step on bar 4, pull rod 5, connector sleeve 6, the first rubber corrugated section 601, attachment base 7, column 8, abduction rod 9, the second rubber Glue bellows segment 901, jack 902, handle 10, retaining ring 11, training rod 12 strike ball 13, spring linkage section 14, and part 15 of serving a ball is prevented Guard bar 16, fender rod abduction rod 1601, sunpender 17, lifting hole(eyelet) 1701, lifting rope 18, fastener 19 of serving a ball, function seat 20, racket card slot 2001, racket handle jack 2002 and demarcation plate 2003；The connector sleeve 6 is solid by the solid first rubber corrugated section 601 of bottom It is scheduled on the top surface middle position for aggravating pedestal 1, forms right angle setting；The connector sleeve 6 is screw thread luminal structure, is led in inner cavity The mode for crossing screw threads for fastening installation is equipped with attachment base 7, and it is integrally-built column 8 that the top of attachment base 7 is equipped with therewith；Institute The top for stating column 8 is equipped with retaining ring 11 further through the mode of screw threads for fastening, and the top of retaining ring 11 is equipped with handle 10；The button The outer wall of set 11 is connected with the arc-shaped rod that training rod 12 and spring linkage section 14 are constituted, and in the arc plate terminal of composition The impact ball 13 of rubber net chondritic is installed；The side of the column 8 is also equipped at one by welded connecting rod The function seat 20 of box body structure, and the abduction rod 9 of a left-hand bending structure is welded in the other side of column 8.

Wherein: function trough 2 is provided with the top surface right positions for aggravating pedestal 1, and is inlayed in this vallecular cavity by running through Thread bush 3 be equipped with and step on bar 4, and the pull rod 5 of U-bend rod structure is also welded in the top side for stepping on bar 4 again, steps on bar 4 and pacify Equipped with pull rod 5, so that stepping on bar 4 after device by impact force shakiness due to being moved in present apparatus batting training process convenient for foot Or foot draws pull rod 5 that the present apparatus is retracted return.

Wherein: abduction rod 9 is poured by double rod section and the second intermediate rubber corrugated section 901, and in the rod segment of top A socket hole 902 is offered, it can be seen that service part 15 can carry out the adjusting of upper and lower position, after adjusting, by existing skill The standard component of art is inserted into jack, and height is made to change, flexible and changeable under battle conditions when service training.

Wherein: service part 15 is sleeved in the top rod segment of abduction rod 9 by round pipe fitting, and in the circle of service part 15 Through-hole corresponding with jack 902 is also provided on pipe fitting, due to being designed as between the bottom pipe fitting and lifting rope 18 of service part 15 30 centimetres of safe distance prevents tennis racket square stance, and racket side strikes on the pipe fitting of service 15 bottom of part, improves knot Structure reasonability.

Wherein: fender rod 16 is the welding rod piece of the rear wall upper position of service part 15, and the fender rod 16 is the curved of Z-shaped Bar, and the rod segment fender rod abduction rod 1601 of its most left rear side is stretched towards rear side, is described herein as structure such as Fig. 4, shown in Fig. 5, The setting of fender rod 16 is placed exactly in the rear side of lifting rope 18, and lifting rope 18 is struck when throwing away backward, is just stopped by fender rod 16, Prevent lifting rope 18 from getting rid of excessively high or excessively inclined, the service fastener 19 of bottom hits human body, improves entire real training ball serving device Safety.

Wherein: sunpender 17 is arc welded tube section, it is welded on the round tube wall of service part 15, and sunpender 17 is most left End position offers lifting hole(eyelet) 1701, in such a way that lifting hole(eyelet) 1701 installs lifting rope 18, hangs and is connected with service fastener 19 at one, and serve a ball Fastener 19 is U-shaped fastener structures made of sheet type spring steel, and the specific structure for fastener 19 of serving a ball will be as shown in figure 4, that will hit The tennis beaten is clipped in fastener 19, fixes the tennis greater than 19 outer dimension of fastener naturally in the case where by external force, only When tennis racket strikes, hit the tennis in fastener 19.

Wherein: the right side opening of function seat 20 sets the racket card slot 2001 there are two U-lag mouth structure, the other side and racket card Slot 2001 is corresponding to offer racket handle jack 2002 at two, this compages is used to store tennis racket, makes to train Tennis racket afterwards can be stored, more reasonable than existing structure.

Wherein: the inner cavity middle position of function seat 20 also passes through two panels demarcation plate 2003 and the interior plate of a piece of streamline shape welds It connects and has formed a small-sized slide holder structure, this composite structure is to set multiple tennises for putting rotation, function seat 20 is made to exist It stores in sexual function structure, reinforcing of having got back is promoted, it can thus be seen that the simulated training of present apparatus collection and combat training are one Body, than on existing market, a series of device functionalities on sale are stronger.

When use: the present apparatus utilizes the impact ball 13 on right side to realize normal impact, completes real training, but device is in multiple frequency It can be rotated during beating, if after rotation is severe, stepping on bar 4 by foot or foot drawing pull rod 5 that the present apparatus is retracted return, instruct After practicing a period of time, the tennis in the intermediate tennis displacement structure of function seat 20 is taken out, is placed on service fastener 19, tennis is just The actual combat tennis that formula is had an effect on impact service fastener 19, completes hair ring training, according to individual demand, can send out this actual combat device Ball element 15 is improved upwards from abduction rod 9, and using in the jack 902 of both the bolt of prior art insertions, keeps service part 15 real Existing height and position is adjusted, and makes the tennis being clipped on service fastener 19, and height and position changes, and is improved flexible and changeable when striking Property, and structure has a preferable protective herein, design rationally, the present apparatus many places functional structure it can be seen from herein Addition makes the batting training device of original frame structure on sale in the market, is functionally being improved, and structure is closed Reason.

The embodiment of the present invention is given for the purpose of illustration and description, and is not exhaustively or by this to send out It is bright to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Choosing Selecting and describe embodiment is and to make those skilled in the art to more preferably illustrate the principle of the present invention and practical application It will be appreciated that the present invention is to design various embodiments suitable for specific applications with various modifications.
