As shown in fig. 1 to 4, the ink bag type double-color pen includes two pen components, a pen holder 2 and a pen cap, which are identical in structure and symmetrically arranged; the pen assembly includes: the pen comprises a pen body 1, a sliding sleeve 4, a pressing column 6, a connecting rod assembly 5 and a switching block 8 for rotating the connecting rod assembly 5; wherein, the sliding sleeve 4 is a semi-cylindrical hollow sleeve structure; specifically, the pen holder 2 is a cylindrical structure with one open end.

The pen is characterized in that the pen body 1 is sleeved in the sliding sleeve 4 and detachably connected with the sliding sleeve 4, the sliding sleeve 4 is located in the pen holder 2, the pressing column 6 is arranged on the upper end face of the sliding sleeve 4, the connecting rod assembly 5 is arranged on the pen holder 2, the switching block 8 is arranged on the sliding sleeve 4, and the lower portion of the pen holder 2 is detachably connected with the pen cap. In practical applications, the switch block 8 and the sliding sleeve 4 may be an integrally formed structure.

In order to enable the sliding sleeve 4 to slide up and down along the pen holder 2, a guide strip 201 is vertically arranged on the inner side wall of the pen holder 2, a groove corresponding to the guide strip 201 is formed in the arc-shaped outer end face of the sliding sleeve 4, the guide strip 201 is correspondingly inserted into the groove, and specifically, the length of the groove is greater than that of the guide strip 201. In a preferred embodiment, the two sliding sleeves 4 are provided with elongated ribs and grooves, respectively, into which the ribs are inserted.

The sliding sleeve 4 is of a two-section structure with a small upper part and a large lower part, the switching block 8 is fixedly arranged on the small-diameter section of the sliding sleeve 4, the upper end surface of the switching block is lower than or flush with the upper end surface of the sliding sleeve 4, and the lower end surface of the switching block 8 is an inclined surface; link assembly 5 includes quarter butt 501, montant 502 and stock 503, the quarter butt 501 articulates the setting on pen-holder 2, and quarter butt 501 is located switching block 8 below of terminal surface down, stock 503 wears to establish on the lateral wall of pen-holder 2 and rotates with pen-holder 2 to be connected, the articulated stock 503 of torsional spring is passed through with quarter butt 501 fixed connection, upper end to the lower extreme of montant 502. Specifically, the pen holder 2 is provided with holes at positions corresponding to the short rod 501 and the long rod 502, so that the short rod 501 and the long rod 502 rotate, and the torsion spring is in an initial state when the short rod 501 vertically faces the push rod groove 401 without receiving torsion.

Specifically, a set angle alpha is formed between the lower end surface of the switching block 8 and the horizontal plane, and alpha is larger than 0 degree and less than or equal to 60 degrees. When the lower end surface of the switching block 8 is an arc surface, the angle α is an included angle between a plane where the two ends of the arc surface are located and a horizontal plane. In this embodiment, the lower end surface of the switch block 8 is a flat surface, and the angle α is 45 °.

The upper end face of sliding sleeve 4 with press post 6 fixed connection, press post 6 to stretch out the tip of pen-holder 2, press the cover on the post 6 and be equipped with spring 7, the upper end and the pen-holder 2 fixed connection of spring 7 lower extreme and the upper end that the upper end face of sliding sleeve 4 contacted.

In use, the ink bags of the two pen bodies 1 can suck ink with different colors (for example, red and blue), the two pen bodies 1 are respectively arranged in the two sliding sleeves 4, and then the two sliding sleeves 4 are arranged in the pen holder 2 along the guide strip 201. Taking red writing as an example, when needing to write, pressing a pressing column 6 corresponding to a pen body 1 filled with red ink, wherein the pressing column 6 pushes a sliding sleeve 4 to descend, a spring 7 fixedly connected with the sliding sleeve 4 is stretched, meanwhile, an inclined end surface of a switching block 8 pushes a short rod 501 to rotate towards the side wall of a pen holder 2, a vertical rod 502 fixedly connected with the short rod 501 is also forced to rotate, at the moment, a torsion spring between the vertical rod 502 and the long rod 503 is in a stressed state, when the sliding sleeve 4 descends below the long rod 503, one end of the long rod 503 rotates towards the center of the sliding sleeve 4 under the action of the elasticity of the torsion spring, the other end of the long rod 503 rotates towards the outer wall of the pen holder 2, and finally, one end of the long rod 503 is positioned on the; when the pressing column 6 is released, the spring 7 contracts and the sliding sleeve 4 rises, but the sliding sleeve 4 cannot be reset because the sliding sleeve 4 is blocked by the long rod 503 positioned on the upper end surface, and the pen body 1 in the sliding sleeve 4 can be used for writing. After writing, the accessible is rotatory stretches out the tip of the stock 503 of penholder 2, makes stock 503 reset, and spring 7 shrink rises this moment, and sliding sleeve 4 rises, and quarter butt 501 resets under the effect of torsional spring, and pen body 1 resets. Similarly, when the blue ink is needed to be used for writing, the above process can be performed, and details are not described here.

According to the above, the embodiment of the present invention, by pressing the pressing column 6 downwards, the long rod 503 is rotated to the upper end of the sliding sleeve, and the pen body 1 in the sliding sleeve 4 and the sliding sleeve 4 is kept fixed under the action of the spring 7 and the long rod 503, so as to write, and the alternate writing of two colors is convenient, and the two colors can not affect each other.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that equivalent changes or modifications made by the structure, features and principles of the present invention should be included in the claims of the present invention.
