Abstract
The utility model belongs to sports goods, concretely relates to can train tennis of reaction, this tennis includes core (1), includes in outside covering (2) of core (1), being provided with the screw thread through -hole in the middle of core (1), being provided with focus adjusting block (2) in the screw thread through -hole, screw thread through -hole both ends are provided with stifled cap (4), the utility model discloses can train tennis of reaction is provided with the screw thread through -hole because core (1) is middle, is provided with focus adjusting block (2) in the screw thread through -hole, consequently can change the focus of tennis through the position of adjustment focus adjusting block (2) in the screw thread through -hole, and then can increase the rotation of tennis, the moving trajectory of change tennis, is favorable to improving sportsman's tennis sports level.
Description
Technical field
This utility model belongs to sports goods, be specifically related to a kind of can the tennis of training response.
Background technology
Tennis is the sports of a grace and fierceness, and the origin and the development of tennis can be summarized by four words: breeds in France, is born in Britain, starts universal and forms climax in the U.S., and the present whole world prevailing is referred to as second-biggest-in-the-world ball game.
Improve athletic tennis competitiveness, it is necessary to have quickly quick reaction, by increasing the rotation of tennis, changing the running orbit of tennis, it is possible to increase athletic reaction, but present stage, but without being found to realize the tennis of above-mentioned functions.
Utility model content
In order to solve the problems referred to above, this utility model devise a kind of can the tennis of training response, be conducive to improving athletic tennis competitiveness.
The purpose of this utility model is achieved in that
A kind of can the tennis of training response, including core body, include at the covering outside core body；Being provided with tapped through hole in the middle of described core body, be provided with centre of gravity adjustment block in tapped through hole, tapped through hole two ends are provided with blocking cap.
Above-mentioned can the tennis of training response, also include the clamp for fixing centre of gravity adjustment block position.
More than can the tennis of training response, described centre of gravity adjustment block is provided with " word " gap；It is also equipped with " word " screwdriver for screwing centre of gravity adjustment block.
Beneficial effect: due to this utility model can training response tennis core body (1) in the middle of be provided with tapped through hole, centre of gravity adjustment block (3) it is provided with in tapped through hole, therefore, it is possible to by adjusting the centre of gravity adjustment block (3) position in tapped through hole, change the center of gravity of tennis, and then the rotation of tennis can be increased, change the running orbit of tennis, be conducive to improving athletic tennis competitiveness.
Accompanying drawing explanation
Fig. 1 is that this utility model can the structural representation of tennis specific embodiment one of training response.
Fig. 2 is that this utility model can the structural representation of tennis specific embodiment two of training response.
In figure: 1 core body, 2 coverings, 3 centre of gravity adjustment blocks, 4 blocking caps, 5 clamps.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model detailed description of the invention is described in further detail.
Specific embodiment one
The present embodiment can the tennis of training response, structural representation is as shown in Figure 1.This tennis of training response can include core body 1, include at the covering 2 outside core body 1；Being provided with tapped through hole in the middle of described core body 1, be provided with centre of gravity adjustment block 3 in tapped through hole, tapped through hole two ends are provided with blocking cap 4.
Specific embodiment two
The present embodiment can the tennis of training response, structural representation is as shown in Figure 2.On the basis of specific embodiment one, further restriction also includes the clamp 5 for fixing centre of gravity adjustment block 3 position.
This structure qualification, it can be ensured that centre of gravity adjustment block 3 will not occur spin to change racket center of gravity in motor process, and then tennis center of gravity can be kept constant.
It should be noted that those skilled in the art can design the concrete structure of clamp 5 as required, no longer describe in detail in this application.
Specific embodiment three
The present embodiment can the tennis of training response, on the basis of specific embodiment one or specific embodiment two, limit further on centre of gravity adjustment block 3 and be provided with " word " gap；It is also equipped with " word " screwdriver for screwing centre of gravity adjustment block 3.
Present embodiments provide a kind of structure how screwing centre of gravity adjustment block 3 and instrument.
