Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the utility model includes blood collecting tubulasis 1, vein blood taking needle 7, is oriented to needle guard 5 and connecting seat；
The one end for being oriented to needle guard 5 is fixedly connected with connecting seat, and the other end is set to needle point structure, by being oriented to needle guard 5
Needle tip first vein blood vessel can be accurately positioned；
It is oriented in needle guard 5 and is provided with guiding needle tray 9, is oriented to the insertion of needle tray 9 and is entirely oriented to needle guard 5, be oriented to the appearance of needle guard 5
Face is provided with bar-shaped trough 6, bar-shaped trough 6 and is provided with sliding block 8；
Vein blood taking needle 7 is arranged in guiding needle tray 9, and the needle tip of vein blood taking needle 7 is worn from the needle tip for being oriented to needle guard 5
Go out, sliding block 8 is extruded and fixed on vein blood taking needle 7；
Flexible drive chamber 15, cushion chamber 12, soft connecting tube 11, spring 13 and hard connecting tube are provided with connecting seat
10, soft connecting tube 11 is located in cushion chamber 12, and spring 13 is arranged in flexible drive chamber 15, and vein blood taking needle 7 is by elasticity
Driving chamber 15 is worn to flexible drive chamber 15 and is connected with one end of soft connecting tube 11, and the other end of soft connecting tube 11 passes through
Hard connecting tube 10 is connected with blood collecting tubulasis 1, and hard connecting tube 10 is fixed in connecting seat, and spring 13 is enclosed within vein blood taking needle 7
On, vein blood taking needle 7 is fixedly installed push pedal 14, and spring 13 is installed between push pedal 14 and the inwall of flexible drive chamber 15.
