It is moved in slot 12, is accommodated in the needle tubing 222 in piercing assembly 22 in protective case ontology.
When piercing assembly 22 is separated from indwelling component 21, needle stand handle 2212 by card slot 12 to close to card slot 12
The direction of cecum 121 is mobile, and in the process, the second shaft portion of the butt joint body 2213 of needle stand ontology 2211 will be with the first conical walls
142 and second conical walls 162 contact so that the first extension 14 and the second extension 16 are to the axis far from protective case ontology
Direction distortion enables needle stand handle 2212 to be smoothly moved to the cecum 121 of card slot 12.As shown in figure 11, when needle stand handle
2212 when being moved to the cecum 121 of card slot 12, and the first conical walls 142 and the second conical walls 162 are docked with needle stand ontology 2211
The second shaft portion of body 2213 disengages relationship, and the first extension 14 and the second extension 16 will be under the action of natural resiliency power
It restores to the original state, at this point, the first confined planes 141 of the first limiting section and the second confined planes 161 of the second limiting section are respectively positioned on needle stand
The abutment face 2216 of the butt joint body 2213 of ontology 2211 is on the mobile track in the direction of the butt end 11 close to protective case ontology.
That is, piercing assembly 22 is mobile to the direction far from butt end 11, needle stand handle 2212 connects the cecum 121 with card slot 12
Touching；Piercing assembly 22 is mobile to the direction close to butt end 11, and the abutment face 2216 of needle stand ontology 2211 will be with the first confined planes
141 and second confined planes 161 contact, thus limit piercing assembly 22 with respect to protective case ontology be axially moved, guarantee needle tubing 222 receive
It will not be stretched out again after being contained in protective case ontology.After needle stand handle 2212 is moved to cecum 121 of card slot 12, make protective case
Ontology is separated with casing seat 211, and the needle tubing 222 of piercing assembly 22 will be always positioned in protective case ontology, by protective case ontology and
Used piercing assembly 22 is thrown away together.
A kind of safety protective cover 10 provided in this embodiment, can be to the needle in the piercing assembly 22 isolated with indwelling component 21
Pipe 222 plays a protective role, and avoids the generation of safety accident.
In the present embodiment, the first extension 14 and the second extension 16 are formed on protective case ontology, the first extension 14
Second confined planes 161 of the first confined planes 141 and the second extension 16 are in the same plane, so that 141 He of the first confined planes
Second confined planes 161 can be contacted with the abutment face 2216 on needle stand ontology 2211 simultaneously, have better restraining ability.This
Outside, since the first basal plane 143 of the first extension 14 is concordant with the first cell wall 122 of card slot 12, the second of the second extension 16
Basal plane 163 is concordant with the second cell wall 123 of card slot 12, so that needle stand handle 2212 will not be with during mobile in card slot 12
First basal plane 143 and the contact of the second basal plane 163, the first extension 14 and the second extension 16 will not be because of needle stand handle 2212 and the
One basal plane 143 and the second basal plane 163 are contacted and are deformed.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
