Accompanying drawing explanation
In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment being clearly and completely described.
Referring to Fig. 1, this detailed description of the invention is achieved by the following technical solutions, it comprises the shell 1 doubling as shank, a cavity is provided with in this shell 1, bottom in this cavity is provided with a piston hole 2, be provided with in this piston hole 2 one with it piston coordinate piston head 6, the other end of this piston head 6 is provided with piston rod 3, the other end of described piston rod 3 is axially across the end of shell 1, the side of described piston rod 3 is axially arranged with tooth bar, the side of described shell 1 upper end is provided with the gear 4 with tooth bar engagement fit, be provided with bottom described gear 4 one with the location tenon 5 of tooth bar snap-fit engagement, the other end of this tenon extends shell 1, described piston rod 3 is provided with the positioning boss 7 that a circle and shell 1 inner chamber are closely slidably matched, the top of this positioning boss 7 is provided with only limit 8, location, this location is stopped limit 8 and is fixed on the inwall of shell 1, the hole be closely slidably matched with piston rod 3 is provided with in the middle part of it, described boss 7 and location are only provided with piston rod spring 11 between limit 8, the bottom of described piston hole 2 be provided with dock with pipette socket 13.
One end bent outward that described location tenon 5 extends shell 1 folds depression bar 51, described shell 1 extends outward safe edge 9 along the both sides of depression bar 51, the middle part of described depression bar 51 is rotatably assorted by bearing pin and safe edge 9, the adjacent one end that described tenon 5 is positioned at the close piston rod 3 of shell 1 is provided with one end chimb 10, is provided with tenon spring 12 between this chimb 10 and shell 1.
