Often can all around swing, when swing stop when, ball is in fixed position, batting of swinging the bat when static when, continuous training
Shot, but this scheme, because ball is fixed on pendulous device, the drop point after can't see actual batting can not judge
The actual effect of batting, training effect are limited；
It, will by elastic force after batting 2. stretch cord training aids is to be fixed on tennis on the weight of ground by stretch cord
The tennis hit pulls back, and is batted next time, but due to batting during club rotate, will lead to stretch cord and hold very much
It easily knots, influences route of batting, it can not visual assessment ball-hitting quality；
3. elasticated net training aids is self-possessed heavier, and elasticated net limited area, beginner, which is easy to beat in ball, to fly, but very
Difficulty gets to tennis on elasticated net, trainer is required relatively high, and trainer is needed to have been provided with good tennis technology；
4. the simulated training of two people can not be carried out, or can be suitble to 2 human simulations training apparatus structure excessively
Complexity, higher cost are also not suitable for household or friend playing in field or roadside.
Such as the utility model patent tennis training machine of Publication No. CN202620642U, a kind of " net is mentioned in the literature
Ball training aids, the elastic long rope including tennis and one end connection tennis, the other end of elastic long rope are connected with pouring weight, constitute weight
Fixed-point apparatus.The pouring weight of the utility model can be used as the fixture of elastic long rope end, and weight, volume can be designed to
Suitable specification, not only fixed point is fixed reliable, will not loosen displacement, and avoids the suitable fixed point of searching or fixture
Time waste, it is also easy to carry, facilitate tennis to practice." by its binding directly for tennis and weight in view of the above, it can not solve
The problem of stretch cord knots.
Such as a kind of tennis training machine of the utility model patent of Publication No. CN205198895U, " one is mentioned in the literature
Kind tennis training machine, the elastic long rope including tennis and one end connection tennis, the tennis are placed in tennis bag, and tennis bag is set
There is sack section, sack section connects long rope through active section, and long rope end connects elastic long rope through active section.Solves single tennis instruction
The problem for practicing oil, the long rope that tennis is connected when it is simple, easy to use to have the characteristics that structure, and training does not beat section, easy to carry,
Tennis is facilitated to practice." combine above and its one end of its visible stretch cord of specification is tennis, other end is buckled in finger and buckles,
It still remains the case where knotting on finger, and is only suitable for 1 individual training.
Such as a kind of elastic force tennis ball hitting training aids of the utility model patent of Publication No. CN207071207U, mentioned in document
" the utility model discloses a kind of elastic force tennis ball hitting training aids, belong to Sports training apparatus technical field.Tennis ball hitting instruction
Practicing device includes: horizontal dovetail groove, the first slide plate, first support bar, second support bar and the second slide plate, and the first slide plate and second are slided
Plate is connect with horizontal dovetail groove, and the first slide plate is fixedly connected with first support bar, and first support bar is equipped with horizontal rod, water
One end of flat hanging rod sets through-hole, and the upper end of first support bar is equipped with internal screw thread, horizontal rod one end and first equipped with through-hole
The upper end of strut is bolted, the other end tennis connection of horizontal rod；The right end of second slide plate and second support bar
Lower end connection, the left end of the second slide plate are fixed with the first spring, and the other end of the first spring is connected with counter weight base；Second support
Bar upper end is fixed with multiple elastic striking plates, is connected between elastic striking plate by second spring.The elasticated net of the utility model
Ball batting training aids, structure is simple, can effectively promote batsmanship.", from the above, it is seen that its elasticated net limited area, begins to learn
Person, which is easy to beat in ball, to fly, and is but difficult to get to tennis on elasticated net, that is, is not suitable for beginner or amusement is used, and is suitable for having
The group of standby certain good basis tennis technology.
Such as a kind of tennis training device of the patent of invention of Publication No. CN105214295B, mention that " present invention relates in document
And a kind of tennis training device, including pedestal, elastic string and buckle tennis, the elasticity is connected between pedestal and buckle tennis
Rope；There is angular transducer and tension sensor on the pedestal, further include PLC system, for recording angular transducer and drawing
The numerical value of force snesor.The device can not only provide one kind in no place, the device of single tennis training, moreover it is possible to improve tennis instruction
Practice level, increases trained enjoyment.", from the above, it is seen that it further relates to angular transducer and tension sensor and PLV system,
Device is relative complex, and still without solving the problems, such as that tennis rotates kinking.
The purpose of the utility model is to provide a kind of tennis training devices of easy not kinking, are set by simple structure
Meter and easy operation, to help beginner's training net playing skill art and realize the enjoyment to play tennis, and beginner's quantity is a people
Or two people.
Summary of the invention
The purpose of this utility model is achieved through the following technical solutions:
A kind of tennis training device of simple not kinking, including columns assemblies, stretch cord, miniature bearing A, connector, band
The tennis of threading hole；The columns assemblies are rotatable；The columns assemblies are connected with stretch cord one end；The stretch cord is worn
Enter in the tennis with threading hole；The miniature bearing A Internal and external cycle is connected with connector respectively；The connector and stretch cord phase
Even.
Further, the columns assemblies include column, pedestal and bearing B.
Further, the column is nested on bearing B.
Further, the bearing B can be in column bottom, can also be in the middle part of column and top.
Further, when bearing B is located at column bottom, the outer ring of bearing B is fixed on the base, the inner ring of bearing B with
Column is fixed together, and column is connected with stretch cord one end.
Further, when bearing B is located at column middle part and top, the inner ring and column of bearing B is fixed together, and also wraps
Casing is included, covers pipe sleeve in the outer ring of bearing B.
Further described sleeve pipe is connected with stretch cord one end.
Further, the outer ring of the miniature bearing A is connected with a connector, the inner ring of miniature bearing A and other one
A connector is connected.
Compared with existing tennis training machine, the utility model is had the advantage that
(1) rotatable columns assemblies can prevent tennis rope to be wrapped on column；
(2) the miniature bearing A among stretch cord is used to eliminate the torsion of tennis rotation generated to rope；
(3) height of adjusting post can simulate the height of tennis court block, in this way it can be seen that the batting of oneself was
Net or off line, the label that tie surface is done, it can be seen that in play whether tennis drop point, while can be fought each other with two people.
