Fig. 2 is a kind of structural schematic diagram at another visual angle of Tiebar structure for syringe pump of the utility model；
Fig. 3 is a kind of structural schematic diagram at another visual angle of Tiebar structure for syringe pump of the utility model.
Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that and described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Many details are explained in the following description in order to fully understand the utility model, but this is practical new
Type can also be implemented using other than the one described here other way, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case where novel intension, therefore the utility model is not limited by the specific embodiments disclosed below.
It as shown in Figure 1 to Figure 3, is a kind of structural schematic diagram of Tiebar structure for syringe pump of the utility model；This
Tiebar structure in utility model, including pull rod 1, draw-bar seat 2 and the extensible member 3 for being set to 1 outer surface of pull rod；The pull rod 1
It is placed on the draw-bar seat 2, pull ring 4 is additionally provided on the draw-bar seat 2, pull ring 4 is equipped with through-hole, the pull ring 4 and pull rod 1
Positioned at the both ends of the draw-bar seat 2；The end face that the pull ring 4 is connected to the draw-bar seat 2 includes cambered surface 41 and cambered surface 42；It is described
Fricting strip 6 is additionally provided on draw-bar seat 2.
The pull ring 4 is located at the lower end of the draw-bar seat 2 as a preferred technical solution, and the fricting strip 6 is placed in described
The lower end surface or side end face of pull rod 4, preferably, the diameter dimension of the pull ring 4 are slightly larger than the index finger size of manpower.
The draw-bar seat 2 is equipped with cavity, is equipped with multiple gussets 5, illustratively, the multiple link of boards in the cavity
