Below, in conjunction with accompanying drawing and specific embodiment, the utility model is described further:

In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying No device or element must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as limiting the invention.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of this invention. The terminology used in the description of the utility model herein is only for the purpose of describing specific embodiments, and is not intended to limit the utility model.

A hand-held injection dispenser as shown in Fig. 1, Fig. 2 and Fig. 3 includes a dispensing base 10, a dispensing rod 13 and a dispensing head 15, a driver and a dispensing groove 16 are arranged on the distributing base 10, and the distributing rod 13 It is slidably installed on the distribution seat 10 , and the distribution rod 13 can slide close to or away from the distribution groove 16 . A distribution head 15 is provided at the end of the distribution rod 13 close to the distribution groove 16 .

Specifically, the driving member includes a first driving arm 11 and a second driving arm 12, the first driving arm 11 is hinged on the distribution base 10, and the other end of the first driving arm 11 is formed as a pressing end, and the above-mentioned second driving arm One end of the arm 12 is hinged on the first driving arm 11; the other end of the second driving arm 12 is formed as a linkage end, which can be abutted against the distributing rod 13, and when the pressing end is stressed, the linkage end drives the distribution The rod 13 slides close to the dispensing slot 16 .

On the basis of the above structure, when using the hand-held injection dispenser of the present utility model, the injection liquid tube 20 can be assembled in the distribution groove 16 of the distribution seat 10, and then the distribution head 15 of the distribution rod 13 can be correspondingly placed in the distribution groove 16 Afterwards, by manually pressing the pressing end of the first driving arm 11, the pressing end moves downward, and then drives the end of the second driving arm 12 hinged at the bottom end of the first driving arm 11 to rotate downward. , and then drive the linkage end of the second driving arm 12 close to the dispensing groove 16, the dispensing head 15 can be pushed in the injection liquid tube 20 to realize the distribution of liquid.

It should be noted that after the assembly is completed, the first driving arm 11 is manually pressed, and the second driving arm 12 and the distributing rod 13 are linked to realize liquid distribution without external power driving, and the operation is convenient. And the liquid doses of different injection liquid tubes 20 are different, the lengths of the injection liquid tubes 20 are different, and the second driving arm 12 of the present application can abut against different positions of the distribution rod 13, which is suitable for injection liquid tubes 20 of different lengths Internal liquid distribution, so the scope of application is wider.

Further, the distributing rod 13 may also be provided with a plurality of snap-in slots 131, and the plurality of snap-in slots 131 are distributed at intervals in the length direction of the distributing rod 13. During assembly, after the injection liquid tube 20 is assembled in the distribution groove 16, The dispensing head 15 can match the length of the injection liquid tube 20 to drive the dispensing rod 13 in different positions of the dispensing seat 10. At this time, the linkage end of the second driving arm 12 can be snapped into one of the slots 131 corresponding to the dispensing rod 13 .

Thereafter, press the pressing end of the first driving arm 11, and then the linkage end of the second driving arm 12 can be connected with the distributing rod 13 through the slot 131, and realize linkage with the second driving arm 12, while the linkage of the second driving arm 12 The end is connected with the card slot 131, which can realize detachable assembly on the one hand, and can also make the sliding of the distribution rod 13 more stable on the other hand.
