Abstract
The invention discloses a multifunctional eraser. The multifunctional eraser comprises a basal body (1), a rotating cover (2), a fixed base (3), a lock (4) and an eraser (5), and is characterized in that the basal body (1) is connected with the fixed base (3), wherein the fixed base (3) is connected with the rotating cover (2); the basal body (1) and the rotating cover (2) are combined to form a circular structure; the lock (4) is arranged on the fixed base (3); and the eraser (5) is arranged on the basal body (1) in the rotating cover (2). The eraser is arranged on the basal body in the rotating cover, so that the eraser can be prevented from falling on the ground to be damaged through stepping by persons; the lock is arranged on the fixed base to prevent the eraser from being stolen and used by other persons; and the multifunctional eraser has the advantages of novel structure, convenience for use and complete functions.
Description
Technical field
The present invention relates to a kind of rubber, particularly relate to a kind of multifunctional eraser.
Background technology
Rubber in use, easily drops in place, will be trampled bad by people because of carelessness like this, and because some is age little also innocent student in the user of rubber, therefore often can steal the rubber with other people.For above-mentioned reasons we can design a kind ofly anti-to trample, the multifunctional eraser of anti-theft.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind of rubber is located at matrix in swivelling cover, can prevent rubber from dropping and locally be trampled bad by people, and holder is provided with lock, can prevent from rubber from being stolen by other people to use, there is novel structure, easy to use, the multifunctional eraser of multiple functional advantage.
For solving the problems of the technologies described above, the invention provides a kind of multifunctional eraser, comprise matrix, swivelling cover, holder, lock, rubber, it is characterized in that: described matrix is connected with holder, described holder is connected with swivelling cover, described matrix and swivelling cover combine rounded structure, and described holder is provided with lock, and described rubber is arranged on matrix and swivelling cover is inner.
Further, described rubber center offers the circular hole identical with holder diameter, and described rubber is located on holder by its circle hole sleeve.
Further, described matrix, swivelling cover, holder adopt metal or plastics to make.
Compared with prior art, beneficial effect of the present invention is:
Rubber is located at matrix in swivelling cover by the present invention, can prevent rubber from dropping and local be trampled bad by people, and holder is provided with lock, can prevent rubber from being stolen use by other people, have novel structure, easy to use, multiple functional advantage.

Detailed description of the invention
Below to being elaborated preferred embodiment of the present invention by reference to the accompanying drawings, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
See Fig. 1, shown in Fig. 2 and Fig. 3, a kind of multifunctional eraser, comprise matrix 1, swivelling cover 2, holder 3, lock 4, rubber 5, described matrix 1 is connected with holder 3, described holder 3 is connected with swivelling cover 2, described matrix 1 combines rounded structure with swivelling cover 2, described holder 3 is provided with lock 4, it is inner with swivelling cover 2 that described rubber 5 is arranged on matrix 1, described rubber 5 center offers the circular hole identical with holder 3 diameter, described rubber 5 is located on holder 3 by its circle hole sleeve, described matrix 1, swivelling cover 2, holder 3 adopts metal or plastics to make.
When there is use: first lock 4 to be turned clockwise certain angle (as shown in Figure 2) with key, now holder 3 is locked, then be in open mode, afterwards swivelling cover 2 is rotated in matrix 1, now rubber 5 just out exposed (as shown in Figure 3), at this moment just can employ.
To sum up, rubber is located at matrix in swivelling cover by the present invention, can prevent rubber from dropping and local be trampled bad by people, and holder is provided with lock, can prevent rubber from being stolen use by other people, have novel structure, easy to use, multiple functional advantage.
The foregoing is only better embodiment of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; in every case those of ordinary skill in the art modify or change according to the equivalence that disclosed content is done, and all should include in the protection domain recorded in claims.
