To achieve the goals above, the technical solution adopted in the utility model is: a kind of for making the injection of negative pressure source
Device piston lever fixing apparatus, including syringe and piston rod further include built-in piston lever fixing apparatus on the piston rod, piston
The global shape of lever fixing apparatus is a quarter cylindrical body；The piston lever fixing apparatus includes being located at the fixed dress of piston rod
Tail portion is set close to the fixing end of syringe injection port, stationary body and is located at piston lever fixing apparatus head and tailpiece of the piston rod head
The press end of position fitting；The fixing end, stationary body are connected with press end integration；One side end face of the fixing end
On be provided with the arc-shaped slot matched with the circular open of syringe；Two vertical sides at the press end are led with fixed respectively
At 10 degree of angles, two vertical sides for pressing the side end face and press end at end are respectively perpendicular two connected vertical sides of body.
Preferably, the shape of the arc-shaped slot in the fixing end is quadrant arcuation, the groove depth of arc-shaped slot
For 0.5cm.
Preferably, the material of the piston lever fixing apparatus is polypropylene, and toughness of material is good, and intensity is high.
The beneficial effects of the utility model are: syringe, which provides negative pressure, needs that piston is disposably drawn the higher position of cause, it is living
The fixation of stopper rod is most important, easy to operate, and fixed device is not easy to slip, and does not influence vacuum effect.By on the device
One arc groove is connected on one of the arc port at the top of syringe, and piston rod is preferably fixed with syringe,
Lever principle is utilized simultaneously, certain angle is set in the bottom of device, can be made directly by simply pressing end position
It obtains the other end to tilt, and then the arc groove on device can be disposably clamped on the injector, reach fixed effect.
Detailed description of the invention
