The specific embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are done concrete description:

See also Fig. 1, it is in the utility model preferred embodiment, the schematic appearance of a structure.As shown in the figure, of the present utility model structure comprises a shaft of a writing brush 1, a plurality of pen core monomer 2 (only showing one of them in this figure), a metal tube 3 and and presses and touch unit 4.The shaft of a writing brush 1 can be transparent material and constitutes, and grips for the user, has an arrival end 11 and a port of export 12.

The arrival end 11 and the port of export 12 respectively have an inlet and an outlet, and inlet and outlet are the holding channels that is communicated with in the shaft of a writing brush 1.Those pen core monomers 2 are connected in series mutually and are arranged in the holding channel, and one of them pen core monomer 2 protrudes in the port of export 12 for writing by outlet.

The outside of metal tube 3 has a plurality of ring-type rags with as decorating, and metal tube 3 bottoms are socketed on the shaft of a writing brush 1.Pressure is touched the top that unit 4 is arranged at metal tube 3, can be made of an erasing rubber material or a plastic material, can be a cylinder in the moulding or decorate body by extending one on the cylinder again.

As shown in Figure 1, pressing and touching unit 4 is a cylinder that is made of the erasing rubber material, but also can be as shown in Figure 2, press to touch unit 4 ' and constituted by plastic material, and by the decoration body that extends the doll moulding on the cylinder.It should be noted that decorating body can have design miscellaneous, is not limited by this drawing.

Then, see also Fig. 3, it is in the utility model preferred embodiment, the part section of a structure and decomposing schematic representation.As shown in the figure, the arrival end 11 of the shaft of a writing brush 1 has a narrow neck structure, and the diameter dimension of this narrow neck structure is less than the caliber size of the shaft of a writing brush 1.The bottom of metal tube 3 is socketed on the shaft of a writing brush 1 by being located on described narrow neck structure, and wherein, metal tube can set firmly or dismountable mode is socketed on the shaft of a writing brush 1.

The port of export 12 of the shaft of a writing brush 1 has outlet, for protruding in the port of export 12 one of in those pen core monomers 2.The holding channel of the shaft of a writing brush 1 inside is placed those pen core monomers 2, and each pen core monomer 2 comprises a socket part 21 and a pen core 22, and socket part 21 has a front end 211 and a tail end 212.

Metal tube 3 is sheathed on to press and touches unit 4, presses the end face that touches unit 4 to expose metal tube 3, presses the bottom surface of touching unit 4 to be positioned at metal tube 3, utilizes and presses the bottom surface of touching unit 4 that socket part 21 is pressed in the shaft of a writing brush 1.Pressure is touched the unit and be can be an erasing rubber.

See also Fig. 4, in first application examples of its utility model preferred embodiment, the enlarged diagram of pen core monomer.As shown in the figure, socket part 21 is a cylindrical shell, and the diameter dimension of front end 211 has a plurality of ribs less than the diameter dimension of tail end 212 on the tail end 212.Pen core 22 protrudes out from front end 211, and in should use-case, pen core 22 be a pencil pen core.

Simultaneously, see also Fig. 4 A, it is in second application examples of the utility model preferred embodiment, the enlarged diagram of pen core monomer.As shown in the figure, similarly, the socket part 21 ' of pen core monomer 2 ' is a cylindrical shell, and the diameter dimension of front end 211 ' is less than the diameter dimension of socket part 21 ' tail end 212 ', have a plurality of ribs on the tail end 212 ', 21 ' front end 211 ' protrudes out pen core 22 ' from the socket part.

Only, in should use-case, the socket part 21 ' of pen core monomer 2 ' be made with plastics with pen core 22 ', and this socket part 21 ' is formed in one with this pen core 22 ', with the purposes as the pointer of resistance touch screen.

Please later consult Fig. 3.As shown in Figure 3, the front end 211 of the socket part 21 of another pen core monomer 2 of tail end 212 sockets of the socket part 21 of visible those pen core monomers 2 in the shaft of a writing brush of cutting open 1 is so that those pen core monomers 2 are connected in series mutually and are arranged at simultaneously in the shaft of a writing brush 1.

See also Fig. 5, it is the user mode schematic diagram of of the present utility model structure.Of the present utility model structure write for the user, when the pen core 22 of the pen core monomer 2 that protrudes in the port of export 12 is write to blunt, the user can be taken out by the pen core monomer 2 of the port of export 12 blunt, and metal tube 3 and the pressure that is arranged at metal tube 3 tops are touched unit 4 take off by arrival end 11, so that the pen core monomer 2 of blunt is inserted in the shaft of a writing brush 1 via arrival end 11, make whole string pen core monomer 2 promote another pen core monomer 2 forward and protrude in the port of export 12.

Will be when the pen core monomer 2 of blunt has been inserted the shaft of a writing brush 1 via arrival end 11 when user's desire, can utilize to press and touch unit 4 pen core monomer 2 is pressed in this shaft of a writing brush 1.As shown in Figure 4, arrival end 11 is inserted by the user elder generation front end 211 of the pen core monomer 2 of blunt, then, with thumb and middle finger clamping metal tube 3, touch unit 4 with the forefinger light press, so that the bottom of metal tube 3 is placed in the tail end 212 of pen core monomer 2, and the application of force presses the bottom surface of touching unit 4 that pen core monomer 2 is pressed in the shaft of a writing brush 1 to utilize.

In addition, as shown in Figure 6, it is non-dismountable because metal tube 3 ' also may be fixedly arranged on the shaft of a writing brush 1, the user also can touch pressure unit 4 and take off separately, inserts arrival end 11 by the metal tube 3 ' front end 211 of the pen core monomer 2 of blunt, then, touch unit 4 with thumb and middle finger clamping pressure, middle finger peaks at metal tube 3 ', and the application of force is touched unit 4 with pressure and pressed down then, presses the bottom surface of touching unit 4 to promote pen core monomer 2 to pass metal tube 3 ' and enter in the shaft of a writing brush 1 to utilize.

Thus, can avoid in the prior art, the user directly contact with thumb pen core monomer 2 tail end 212 the bottom surface and cause application of force place too to concentrate the problem cause pointing the contact-making surface discomfort.What is more, touching unit 4 when pressure is a cylinder erasing rubber, and the metal tube 3 of can arranging in pairs or groups visually produces the moulding image of traditional pencil, makes of the present utility model structure have the design sense of unique innovation in appearance.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
