[0024] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, below will be combined with the drawings to the utility model make further detailed introduction.

[0025] The utility model discloses a portable pen type syringe.

[0026] The utility model provides a Figures 1-3 The utility model discloses a portable pen type syringe including pen body 1 and the pen cap 2 of setting in pen body 1 lower extreme, the pen cap 2 is hollow tubular and is set, and the outer wall of pen body 1 is set with moving groove 3, and the sliding block 4 is slidably arranged in moving groove 3, and the outer wall of pen cap 2 is set with strip hole 5, and the sliding block 4 is fixedly arranged in strip hole 5.

[0027] The bottom of pen cap 2 is fixedly provided with a plurality of connecting plates 6 which are symmetrically arranged in a ring shape, the outer side of connecting plate 6 is sleeved with protection plate 7, the lower end of a plurality of protection plates 7 is in contact and fit, elastic opening and closing mechanism is arranged between connecting plate 6 and protection plate 7, and the elastic opening and closing mechanism includes crossbar 8, crossbar 8 is rotatably arranged in connecting plate 6, the top of protection plate 7 is provided with rotating groove, connecting plate 6 is located in rotating groove, crossbar 8 is fixedly arranged in rotating groove, both ends of crossbar 8 are sleeved with torsional spring 9, and both ends of torsional spring 9 are fixedly connected with connecting plate 6 and protection plate 7 respectively.

[0028] When the syringe is not in use, multiple protective plates 7 contact each other and cover the bottom of the pen cap 2 under the torsion limit of the torsion spring 9. At this time, the pen cap 2 can protect the injection end of the syringe and try to prevent the injection end from being damaged or contaminated by the outside. At the same time, the pen cap 2 is integrally connected to the pen body 1, which avoids the possibility of the pen cap 2 being lost, so that the syringe can be conveniently carried and used. When injection is required, the pen cap 2 can move longitudinally along the pen body 1. During this process, the injection end of the syringe begins to push the multiple protective plates 7. At this time, the protective plates 7 drive the cross bar 8 to rotate. At the same time, the cross bar 8 rotates in coordination with the connecting plate 6, so that the protective plates 7 rotate stably while the torsion spring 9 is twisted. At this time, the torsion spring 9 can function so that after the syringe is used, when the pen cap 2 moves back to its original position, the multiple protective plates 7 can rotate back to their original position and continue to protect the injection end of the syringe.

[0029] In order to enable the pen cap 2 to move upward stably, the injection end of the syringe is exposed, such as Figure 1 As shown, a driving screw 10 is rotatably provided inside the movable groove 3 , the slider 4 is threadedly sleeved on the outside of the driving screw 10 , and a rotating block 11 is fixedly sleeved on the upper end of the driving screw 10 .

[0030] When injection is required, the user can push the rotating block 11, so that the rotating block 11 drives the driving screw 10 to rotate. At this time, the slider 4 drives the pen cap 2 to move quickly under the sliding limit of the inner wall of the moving groove 3, exposing the injection end, thereby improving the convenience of using the syringe.

[0031] In order to ensure that the syringe can be carried in a variety of ways and to avoid the possibility of falling, such as Figure 2 As shown, a buckle 12 is fixedly provided at the upper end of the outer wall of the pen body 1, and an anti-falling mechanism is provided at the lower end of the buckle 12. The anti-falling mechanism includes a blocking rod 13, which is slidably arranged at the inner lower end of the buckle 12. A pull ring 14 is fixedly provided at the end of the blocking rod 13, and a spring 15 is provided on the rod wall of the blocking rod 13. The two ends of the spring 15 are fixedly connected to the buckle 12 and the blocking rod 13 respectively.

[0032] The setting of the buckle 12 can pin the entire syringe to the outside of the clothing pocket. In order to ensure the carrying stability of the syringe, the pull ring 14 can be pulled to make the blocking rod 13 move laterally. At this time, the buckle 12 can be put on the outside of the ring-shaped object, and the blocking rod 13 can be loosened. Under the elastic force of the spring 15, the buckle 12 and the pen body 1 are blocked, so that the syringe can be stably suspended and cannot fall, further improving the convenience and stability of the use of the syringe.

[0033] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
