Referring to fig. 1 to 4, in the present embodiment, a buckle-type gel ink pen casing is provided, which includes a pen head 1, go up a shell 2 and lower shell 3, still include spring 65, 1 threaded connection of nib is on the surface of last shell 2, go up and be connected through adjusting part between shell 2 and the lower shell 3, slot 5 has been seted up to the bottom of lower shell 3, sliding connection has supporting disk 6 in the lower shell 3, the side fixedly connected with of supporting disk 6 and the lug 61 of slot 5 looks adaptation, thread groove 4 has been seted up on the surface of lower shell 3, thread groove 4's surface threaded connection has ring body 7, the surface and the lug 61 butt of ring body 7, recess 62 has been seted up on the surface of supporting disk 6, the inner wall of recess 62 is provided with flexible piece 63, recess 62 sliding connection has backup pad 64, the both ends of spring 65 are connected with recess 62's inner wall and backup pad 64's fixed surface respectively.

More specifically, in this embodiment, the pen point 1 is rotated to separate the pen point 1 from the upper pen shell 2, then the pen core is placed in the upper pen shell 2, the bottom of the pen core extends into the first groove 62 and contacts with the elastic sheet 63, at this time, the pen core is pressed downwards to deform the elastic sheet 63 until the pen core contacts with the support plate 64, the pen core is clamped by the elastic sheet 63 under the elastic action, shaking during use is prevented, stability during use is improved, the pen can be used by screwing in the pen head, the support plate 6 can be driven by the rotating ring body 7 to move, the top of the pen core is clamped by the pen point 1 and cannot move, so that the pen core is longitudinally clamped by the first spring 65 and the support plate 64 along with the support plate 6, shaking is further reduced, stability is improved, when writing is performed again, the elasticity of the first spring 65 is enough to support the pen core to normally write, and when writing force is too large, the first spring 65 can be compressed, so that the pen core is retracted into the pen point 1, buffering is performed through the first spring 65, the damage to the pen core caused by overexertion is avoided, and the service life of the pen core is prolonged.

Further, in the present embodiment: the adjusting part comprises a clamping block 9 and a second spring 12, the inner wall of the upper pen shell 2 is provided with a plurality of clamping grooves 10 for the clamping block 9 to extend into, the outer surface of the lower pen shell 3 is provided with a second groove 11 for the clamping block 9 to extend into, and two ends of the second spring 12 are fixedly connected with the inner wall of the second groove 11 and the surface of the clamping block 9 respectively.

More specifically, through rotating last shell 2 in this embodiment, hold down shell 3 when rotating, make it keep motionless, rotate through last shell 2, drive draw-in groove 10 and rotate, rotate through draw-in groove 10, press and move fixture block 9 and stretch into in the recess two 11, and make two 12 contractions of spring, when fixture block 9 breaks away from draw-in groove 10, can longitudinal movement last shell 2, adjust the holistic length of a shell, when adjusting to suitable length, reverse last shell 2 again, make fixture block 9 stretch into in another draw-in groove 10 under the effect of two 12 springs, can adapt to the refill of different length, the practicality of a shell has been improved.

Further, in the present embodiment: the surface of the upper pen shell 2 is sleeved with the anti-slip sleeve 13, the anti-slip sleeve 13 is made of rubber, the friction force between the palm and the pen shell is improved by arranging the anti-slip sleeve 13 when the pen is used, the hand slip is prevented, and the stability during writing is improved.

Further, in the present embodiment: the bottom threaded connection of lower shell 3 has visor 8, and the surface of visor 8 is provided with buckle 14, prevents that external impurity from getting into the shell through setting up visor 8 when using, is convenient for carry the shell through setting up buckle 14.

Further, in this embodiment: the elastic pieces 63 are arc-shaped, the number of the elastic pieces is not less than four, the elastic pieces are distributed in an annular array, and at least four elastic pieces 63 distributed in the annular array are arranged, so that the clamping force of the pen core is uniformly distributed, and the shaking of the pen core is reduced.

Further, in this embodiment: the quantity of adjusting part is two to with the symmetric distribution, set up two adjusting part through the symmetry, be difficult for taking place to rock when making last shell 2 and lower shell 3 be connected, improve stability.

The working principle is as follows: this buckle formula gel ink pen shell when the installation, earlier stretch into pen shell 2 in pen shell 3 down, stretch into the in-process, fixture block 9 slides along the inner wall of last pen shell 2, and the shrink of second 12 springs is pressed, slide to when contacting with draw-in groove 10 when fixture block 9, spring two 12 is not receiving pressure, thereby promote fixture block 9 and stretch into in the draw-in groove 10, accomplish the installation of pen shell 2 and pen shell 3 down, correspond lug 61 and slot 5 of supporting disk 6 side again, later with supporting disk 6 in pushing into pen shell 3 down, again with ring body 7 screw in at thread groove 4 surface and with lug 61 butt, can accomplish the installation in pen shell 3 bottoms to 8 threaded connection of visor at last.

When the pen is used, the pen point 1 is separated from the upper pen shell 2 by rotating the pen point 1, then the pen core is placed into the upper pen shell 2, the bottom of the pen core extends into the first groove 62 and contacts with the elastic sheet 63, at the moment, the pen core is pressed downwards to enable the elastic sheet 63 to deform until the pen core contacts with the support plate 64, the pen core is clamped tightly under the elastic action of the elastic sheet 63, shaking during use is prevented, the stability during use is improved, the pen can be used after being screwed into the pen point, the support plate 6 can be driven by the rotating ring body 7 to move, the top of the pen core is clamped by the pen point 1 and cannot move, therefore, the pen core moves upwards along with the support plate 6, the pen core is longitudinally clamped tightly under the action of the first spring 65 and the support plate 64, shaking is further reduced, the stability is improved, when writing is carried out, the elastic force of the first spring 65 is enough to support the normal writing of the pen core, and when the writing force is overlarge, the first spring 65 is compressed, the pen core is retracted into the pen point 1 and buffered through the first spring 65, so that the damage of the pen core caused by over-force is avoided, and the service life of the pen core is prolonged.

When the refill that needs the different length of adaptation when using, through rotating last shell 2, press down shell 3 when rotating, make it keep motionless, rotate through last shell 2, drive draw-in groove 10 and rotate, rotate through draw-in groove 10, press and move fixture block 9 and stretch into in the recess two 11, and make two 12 contractions of spring, when fixture block 9 breaks away from draw-in groove 10, can longitudinal movement last shell 2, adjust the holistic length of a shell, when adjusting to suitable length, reverse last shell 2 again, make fixture block 9 stretch into in another draw-in groove 10 under the effect of two 12 springs, the refill of the different length of adaptation, the practicality of a shell has been improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
