Fig. 2 be the cell taking gun protective sleeve embodiment of Fig. 1 be enclosed within cell taking gun outside state under the structural representation along A-A section;
The structural representation of tubaeform sleeve pipe in the cell taking gun protective sleeve embodiment that Fig. 3 provides for this utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, this utility model is further described.
It should be noted that, in this utility model embodiment, the statement of all uses " first " and " second " is all the parameters in order to the entity or non-equal distinguishing two same names non-equal, visible " first " " second " convenience only in order to state, should not be construed as the restriction to this utility model embodiment, subsequent embodiment illustrates no longer one by one to this.
With reference to accompanying drawing 1 and accompanying drawing 2, the perspective view being respectively the cell taking gun protective sleeve embodiment that this utility model provides and the cross-sectional view under the state being enclosed within cell taking gun outside.
As shown in the figure, described cell taking gun protective sleeve, comprises bag-shaped protective sleeve main body 10 and the horn-like extensive protection that is connected with protective sleeve main body 10 one end overlaps 20, and the two is inner is communicated with; Described horn-like extensive protection cover 20 extends along the direction away from protective sleeve main body 10 and its area of section reduces gradually, and described protective sleeve main body 10 is silica gel material, has certain elasticity.Do not hinder the operation to cell taking gun main body like this, as cocking and the operation discharging puncture needle.Extensive protection cover 20 is silica gel material.
Described protective sleeve main body 10 other end has opening 30, and the edge of described opening 30 is provided with a circle elastic webbing 40, is symmetrically arranged with the auxiliary draw ring 50 of two ear shape on protective sleeve main body 10 lateral surface of opening 30 position;
