The polypropylene has good flexibility, so that the end cover is made of polypropylene, and after the end cover and the outer tube body are sleeved together, the whole pen has good flexibility, and the probability of crashing the whole pen is reduced.

Optionally, the inner tube is a cylindrical inner tube.

Because the outer tube body is made of polypropylene material, and the inner tube body is made of glass (with certain hardness), the structure adopts the cylindrical inner tube body, so that sharp objects on the inner tube body can be reduced as much as possible, and the probability of puncturing the outer tube body is reduced.

The beneficial effects of the utility model are as follows: as long as the outer pipe body is bent to the inner pipe body to be broken, the two solutions can react and emit light, no electrical equipment is needed, and the reliability is high.

Description of the drawings:

fig. 1 is a schematic diagram of a luminous pen.

The reference numerals in the drawings are as follows: 1. a sealing plate; 2. an inner tube body; 301. a first compartment; 302. a second compartment; 4. an outer tube body; 401. a grip portion; 5. a partition plate; 6. a pen core; 7. an end cap.

The specific embodiment is as follows:

the present utility model will be described in detail with reference to the accompanying drawings.

As shown in the attached drawing 1, the self-luminous pen comprises an outer tube body 4, an inner tube body and a pen core 6, wherein the outer tube body 4 is made of bendable transparent plastic materials, a baffle is arranged in the outer tube body 4, the outer tube body 4 is separated into an independent first cavity and a second cavity by the baffle, the first cavity is in a sealing state, the inner tube body is arranged in the first cavity, the inner tube body is a totally-enclosed inner tube body, an oxalate solution is stored in the inner tube body, a hydrogen peroxide solution is stored in the first cavity, the pen core 6 is arranged on the outer tube body 4, the pen core 6 is connected with the second cavity, fluorescent dye is coated on the inner wall of the outer tube body, and the fluorescent dye is positioned in the first cavity.

In this luminous pen, the inner tube adopts fragile material preparation of easily breaking, like glass or hard brittle plastic, stores hydrogen peroxide solution in the inner tube, and has stored oxalic ester solution in the first cavity of outer body 4, so when buckling outer body 4, can break the inner tube body, hydrogen peroxide solution in the inner tube body can with oxalic ester solution reaction release energy transfer for the fluorescent dye realize fluorescent dye and give out light, so this luminous pen need not to use electrical equipment can realize giving out light, and simple structure, adaptability is stronger.
