Put and operate, fixing device is positioned laterally in inner shell body；Sleeve and inner housing are threaded connection, and when extracting medicinal liquid, can turn
Moving sleeve, arranges scale on sleeve, be easy to determine extraction amount, and scale is rotary scale, is often rotated to an angle, and arranges one
Scale, improves scale precision, improves dose accuracy；Action bars outer end is button, convenient to inject after medicinal liquid has been extracted
The push rod opposite direction of device is promoted, and push rod is departed from fixing device, completes to extract the process of medicinal liquid；The setting of block, and button
On the setting that is connected with positioning convex of positioning table position fixing device, Stability Analysis of Structures.
The cross section of described block is provided with crosswise through hole.Cross on crosswise through hole correspondence syringe outer tube
Catch is arranged, and is easy to after push rod enters fixing device position syringe outer tube, and convenient operation push rod enters into fixing device
Row is fixed.
One end of described latch correspondence retainer ring arranges
The cylindrical cavity of shape cavity connection, the opening diameter of conical cavity are less than end diameter.The setting of ladder cavity except
There is provided outside the space of latch, be fix pearl offer movement locus are provided, be easy to the entrance of the push rod end of taper
And fixed pearl is positioned in end recesses.
The invention has the beneficial effects as follows：
Advantages of simple, has reached the purpose accurately got it filled, the magnifier of setting by arranging fixing device and rotary apparatuss
It is easy to observation, easily operates, improve use.
