[0028] The beneficial effects of such a setting are as follows. The eraser of the present utility model has a closable outer shell protection, that is, the block eraser is installed in the sealed cavity between the first shell and the second shell, avoiding the direct exposure of the eraser to contact with other items. Moreover, the first shell and the second shell are detachably connected. When the eraser needs to be used, only the first shell and the second shell need to be separated. In addition, the lighting component installed on the outer shell can also provide a lighting function, with richer functions, greatly enhancing the practicality and interestingness.
[0029] Furthermore, a fixing block 6 protrudes from one side of the second shell 3 corresponding to the sealed cavity 4. The block eraser 1 is recessed with a card slot 7 adapted to the fixing block 6. The block eraser 1 is installed on the second shell 3 through the cooperation of the card slot 7 and the fixing block 6.
[0030] The beneficial effects of such a setting are as follows. Through the cooperation of the fixing block and the card slot, the block eraser is installed on the second shell. When not in use, the block eraser will not roll randomly in the sealed cavity, thus affecting storage. When in use, directly hold the second shell for erasing, and the hand can not contact the block eraser, keeping it clean and hygienic.
[0031] Furthermore, a convex ring 8 extends from the first shell 2 towards the inside of the second shell 3. The first shell 2 is connected to the second shell 3 by inserting the convex ring 8. A first convex rib 9 protrudes from the outer wall of the convex ring 8, and a second convex rib 10 protrudes from the inner wall of the second shell 3. The first convex rib 9 and the second convex rib 10 are arranged relatively and alternately.
[0032] The beneficial effects of such a setting are as follows. The convex ring extends into the inside of the second shell, enabling the first shell and the second shell to form an insertion connection. Then, through the relatively alternating first convex rib and second convex rib, the connection strength of the insertion is improved, increasing the sense of paragraph and the feel of insertion and extraction. The first convex rib is located at a position away from the first shell relative to the second convex rib, and the second convex rib is located at a position close to the first shell.
[0033] Furthermore, the lighting component 5 includes a lamp bead 11, a battery 12, and a switch 13 that are electrically connected to each other. The lamp bead 11 is installed at one end of the first shell 2 away from the second shell 3.
[0034] The beneficial effects of such a setting are as follows. The lamp bead is controlled by the switch to be lit, and the lamp bead is used to provide light. The battery uses a button battery to supply power to the lamp bead, adding a lighting function and increasing the interestingness.
[0035] Further, the first housing 2 includes a first half-shell 14 and a second half-shell 15. The first housing 2 and the second housing 3 are symmetrically arranged along the axis direction of the lamp bead 11. At least one slot 16 is provided on the inner wall of the first housing 2, and at least one plug-in member 17 is provided on the inner wall of the second housing 3. The plug-in member 17 is inserted and connected with the slot 16. A sliding groove 18 for the switch 13 to slide and connect is formed on the side wall of the first housing 2, and an installation groove 19 for installing the battery 12 is provided on the inner wall of the second housing 3.
[0036] The beneficial effects of such a setting are as follows. The first half-shell and the second half-shell are connected together by the insertion and cooperation of the plug-in member and the slot, which is convenient for installation and facilitates the disassembly and assembly of the lighting component.
[0037] Further, an installation cover 20 is included. The installation cover 20 is sleeved around the first half-shell 14 and the second half-shell 15 at the same time, and the center thereof allows the lamp bead 11 to pass through.
[0038] The beneficial effects of such a setting are as follows. The first half-shell and the second half-shell are connected together by the installation cover, which further improves the connection strength between the first half-shell and the second half-shell and makes it more firm.
[0039] Further, the housing further includes a third housing 21 detachably connected to the second housing 3. The connection structure between the second housing 3 and the third housing 21 is the same as the connection structure between the first housing 2 and the second housing 3. A pencil sharpener 22 is provided on the third housing 21.
[0040] The beneficial effects of such a setting are as follows. The third housing and the second housing are also connected by the same insertion connection method as that between the first housing and the second housing, which is convenient for opening and closing. The third housing is also equipped with a pencil sharpener, which adds the function of sharpening pencils. The three-in-one multifunctional eraser has more abundant functions.
[0041] Further, an opening 23 for installing the pencil sharpener 22 is formed on the end face of the third housing 21 away from the second housing 3, and a chip storage cavity 24 is formed between the third housing 21 and the second housing 3.
[0042] The beneficial effects of such a setting are as follows. The pencil sharpener can be installed at the opening, and the pencil can be sharpened directly without opening the second housing and the third housing. Then, the chips are stored in the chip storage cavity between the third housing and the second housing, which is convenient for unified cleaning.
[0043] Further, at least two tail fins 25 are evenly distributed around the third housing 21. One end of the first housing 2 away from the third housing 21 is in a contracted shape, and the outer shape of the housing is in the shape of a rocket.
[0044] The beneficial effects of such a setting are as follows. The overall shape is similar to a rocket, which further increases the interest.
[0045] The above-disclosed is only the preferred embodiment of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
