[0018] The technical scheme in the utility model embodiments will be described clearly and completely below in combination with the drawings of the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] In the description of the utility model, it needs to explain, the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and so on indicate the position relation or position relation based on the position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, a specific orientation and operation, therefore, it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0020] In the description of the utility model, it needs to explain, unless otherwise specified and limited, the terms "installation", "provided with", "connection" and the like should be understood broadly, for example, "connection", can be fixed connection, or detachable connection, or integrally connected; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0021] Please refer to Figures 1-4 The utility model provides an embodiment: a ball cover structure of tennis ball serving machine convenient to connect and store and carry, including body 1, body 1 top is provided with upper ball cover 2, upper ball cover 2 adopts flexible material to be made, such as cloth etc.;

[0022] Among them, body 1 and upper ball cover 2 are all hollow structure design;

[0023] Specifically refer to the description of the drawings Figure 1 And Figure 4 As shown in the drawing, the upper edge inner ring of body 1 is fixedly installed with lower magnetic attraction ring 7, and the lower edge outer ring of upper ball cover 2 is fixedly installed with upper magnetic attraction ring 6 matched with lower magnetic attraction ring 7, and the diameter of upper ball cover 2 is slightly smaller than the diameter of body 1, so that upper ball cover 2 can be inserted in the inside of body 1;

[0024] This kind of structure design, when needing to install upper ball cover 2 on the body 1 of serving machine, upper ball cover 2 can be inserted into the upper inside of body 1 at this moment, during the insertion of upper ball cover 2, the upper magnetic attraction ring 6 outside upper ball cover 2 and the lower magnetic attraction ring 7 of body 1 inner wall will mutually magnetically adsorb, so that the preliminary magnetic attraction positioning connection can be carried out through the mutual adsorption of the two magnetic attraction rings, with good magnetic attraction type fixing characteristics, with the structure use characteristics of preliminary positioning, convenient to use;

[0025] The top end outside body 1 is fixedly installed with not less than two groups of fixed band 3, the top end of fixed band 3 is installed with buckle plug 4, and the bottom end outside upper ball cover 2 is fixedly installed with buckle seat 5 matched with buckle plug 4.

[0026] When the upper ball cover 2 and the machine body 1 are preliminarily positioned and adsorbed by the two magnetic attraction rings, the plurality of buckle plugs 4 between the upper ball cover 2 and the machine body 1 can be inserted into the buckle seats 5, so that the positioning and fixed connection between the upper ball cover 2 and the machine body 1 can be completed.
