According to Chinese utility model patent application No. is a kind of continous way syringe for animals disclosed in 201320667911.0, Including handle, injection tube, piston, injection needle and bottle cap, injection needle is connect by needle cap with injection tube front end, and piston is placed in injection In cylinder, piston rod is fixedly connected with handle, and injection tube is connect with handle front end by nut, is equipped with bottle on the top of injection tube Lid, is connected between bottle cap and injection tube by aspirating needle, and aspirating needle syringe needle passes through bottle cap bottom, and handle is equipped with spring, spring Spring adjusting knob is equipped between handle, handle and piston rod connecting portion are equipped with dose knob.This structure Syringe injection dosage inaccuracy, and in adjustment process, it is complicated for operation, it is time-consuming and laborious.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide veterinary syringe.

The utility model is achieved through the following technical solutions:

A kind of veterinary syringe, including fixed handle, active handle, piston rod, injection cylinder, piston, medicine bottle Connector, needle stand are movably connected between the fixed handle and active handle by elastic movable supports part, institute The front end that needle stand is mounted on the injection cylinder is stated, one end of the piston and the piston rod links together, and described Piston is located at the inside of the injection cylinder；It is integrally formed in the upper end of the fixed handle and is provided with pilot sleeve, it is described Piston rod passes through the pilot sleeve, is equipped with screw thread in one end of the pilot sleeve and adjusts lid, in the pilot sleeve The other end adjusting nut is installed, be machined with open slot on the pilot sleeve, and the screw thread adjusts lid and has and has The turning set of scale, the open slot is for showing scale value.

Further, the vial connector is mounted on the outside of injection cylinder, and the inside phase with the injection cylinder It is logical, flask for medicinal preparations is installed on the vial connector.

Further, aspirating needle is installed between the flask for medicinal preparations and vial connector, the syringe needle of aspirating needle passes through medicine The bottle cap bottom of agent bottle.

Further, it is integrally formed in the upper end of the active handle and is provided with lantern ring, one end of the piston rod Across lantern ring.

Further, the elastic movable supports part includes spring, spring adjusting knob, adjusts rotation using spring and spring The elasticity between fixed handle and active handle is adjusted in button.

Compared with prior art, it the beneficial effects of the utility model are: the structure design of the utility model is reasonable, is using When, flask for medicinal preparations is installed on vial connector, can be replaced for different types of flask for medicinal preparations, does not need to use and lead Pipe, is directly plug-in, and replacement is convenient；By being equipped with aspirating needle between flask for medicinal preparations and vial connector, medical fluid can It is entered in injection cylinder by aspirating needle, can be realized continue in this way can into medicine by forcing in active handle in this way It drives piston rod to be moved, so that piston is moved along injection cylinder, realizes function of injection.The utility model uses Screw thread adjusts lid and is adjusted, and the turning set that screw thread adjusting covers can be realized scale value and show, be convenient for observing, such Regulative mode is simple, time saving and energy saving.
