The opening and closing rod 5 is arranged on the side wall of the handheld sleeve 21 at one end far away from the valve body 4 and is rotatably connected with the side wall of the handheld sleeve 21, and the axial direction of the opening and closing rod 5 is parallel to the radial direction of the guide pipe 27. When the opening and closing rod 5 is rotated, the valve body 4 can be driven to rotate, the through hole 41 can rotate along with the valve body 4, and the stop valve can open and close the blood circulating in the flow guide pipe 27.

Referring to fig. 5 and 7, a shift lever 51 is arranged at one end of each opening and closing rod 5 far away from the valve body 4, the shift lever 51 is perpendicular to the opening and closing rod 5, one end of the shift lever 51 is fixedly connected with the opening and closing rod 5, and the other end of the shift lever 51 extends towards the opening direction of the handheld sleeve 21; when the axis of the through hole 41 is perpendicular to the axis of the delivery tube 27, the levers 51 of the two opening/closing rods 5 are parallel to each other and inclined toward the side wall of the handle sleeve 21, and the lever 51 in the inclined state is set to be a natural state of the lever 51. When the shift lever 51 is in a natural state, the axis of the through opening 41 is vertical to the axis of the guide pipe 27, so that the guide pipe 27 is sealed by the valve body 4; when the guide tube 27 is inserted into the tube 31, the end face of the end 32 can abut against the inclined shift lever 51, and when the end 32 further moves towards the interior of the hand-held loop bar, the shift lever 51 can be shifted, so that the opening and closing rod 5 is driven to rotate, the valve body 4 is rotated to an open state, and when the guide tube 27 is inserted into the tube 31, the end 32 can automatically open the valve body 4, so that blood in the guide tube 27 flows into the tube 31.

Referring to fig. 5 and 7, a reset spring 52 is fixedly connected to each of the levers 51 at an end away from the opening/closing rod 5, and the reset spring 52 extends into the hand-held loop bar at an end away from the lever 51 and is fixedly connected to the outer wall of the flow guide tube 27. When the reset elastic sheet 52 is in a natural state, the shift lever 51 is also in a natural state, so that the axis of the through hole 41 is vertical to the axis of the draft tube 27; when the shifting lever 51 is shifted under the action of the end head 32, the reset elastic sheet 52 can be stressed and bent, and when the end head 32 moves towards the direction far away from the shifting lever 51, the reset elastic sheet 52 is restored under the action of the elasticity of the reset elastic sheet 52, so that the shifting lever 51 is pushed to reset, the shifting lever 51 can be automatically restored to a natural state, and the stability of closing the valve body 4 is ensured.

The implementation principle of the embodiment 2 is as follows: during the use, the needle cover 111 is pulled out from syringe needle 11 earlier to the operator, then inject syringe needle 11 into the animal internally, later the operator holds handheld sleeve pipe 21 on one hand, another hand stretches into handheld sleeve pipe 21 with test tube 3 in, and rotatory body 31 when end 32 removes to screw thread department, make end 32 remove to handheld sleeve pipe 21 inside under the effect of screw thread, so that honeycomb duct 27 pierces through lock bottle pad 34, get into in the body 31, the operator can realize being convenient for to hold the effect of blood sampling subassembly 1 through handheld sleeve pipe 21, and can make things convenient for the ann of test tube 3 with honeycomb duct 27 to tear open, promote the practical convenience of blood sampling device. Meanwhile, the shift lever 51 can be shifted by the movement of the end head 32, so that the valve body 4 is driven to open, the guide tube 27 is enabled to circulate, and the guide tube 27 can draw the animal blood under the action of the vacuum section in the tube body 31, so that the collection of the animal blood sample is completed; and when changing test tube 3, end 32 separates with driving lever 51, and driving lever 51 resets under the effect of shell fragment 52 that resets for valve body 4 closes, and honeycomb duct 27 ends flows, thereby reduces blood and flows out in honeycomb duct 27 when being convenient for change test tube 3, realizes the effect of once only extracting multitube animal blood sample.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
