On, compatible with first push plate is installed on the Antipricking protective case inner wall of locking clamp front end
Two push plates；The length of second push plate to Antipricking protective case front end is greater than Antipricking protective case front end to the syringe needle
The length of front end.
First push plate and the second push plate are ring structure movable set on the lever.
The utility model advantage is that structure is simple, easy to operate.It pulls out after needle by pressing push button downwards, makes to protect
The locking clamp for covering locking rod front end is detached from the first push plate, and under the thrust of adjustable spring, the first push plate pushes second to push away
Plate, so that Antipricking protective case be made to move forward protection syringe needle；It prevents medical staff from stabbing, reduces occupational exposure risk, avoid
Communicable disease is infected, infection risk, the life and health of protection medical staff, transport and post-processing personnel are reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 be in Fig. 1 A-A to cutaway view Amplified image.
Fig. 3 is the enlarged structure schematic diagram of Antipricking protective case in Fig. 1.
Specific embodiment
As shown in Figure 1, 2, Antipricking dialysis puncture needle described in the utility model, including it is soft by syringe needle 1, lever 2, PVC
Matter conduit 3, needle base 4, needle base lid 5 and be set in 2 front end of lever the needle wing 6 constitute dialysis puncture needle ontology；It is in one's hands
Fixed ring 7 is set on handle 2 at rear end, 7 rear end of fixed ring and 2 lateral wall of lever are connected, between fixed ring 7 and lever 2
Form pressing chamber 8；Annular Antipricking protective case 9, Antipricking protective case 9 are movably installed on the lever 2 of 7 front end of fixed ring
Sliding chamber 10 is formed between lever 2,9 rear end of Antipricking protective case is installed with spring retaining plate 11, and spring retaining plate 11 is living
Dynamic to be set on lever 2, the arranged on left and right sides of Antipricking protective case 9 offers the sliding slot 12 being slidably matched with the needle wing 6 from front to back
(as shown in Figure 3) guarantees that Antipricking protective case 9 can not be by the blocking forward slip of the needle wing 6；By opening up in fixed ring 7
Mounting hole is movably installed with push button 13, is installed with protection lock set on 13 front side wall of push button in pressing chamber 8
Only bar 14, protective case locking rod 14 pass through spring retaining plate 11 horizontally forward and extend into sliding chamber 10, protective case locking rod
14 front ends are provided with locking clamp 15, pass through hinged shaft 17 and 2 side wall of lever hinge (hinged shaft with torsional spring 16 at rear end
17 axis is vertical with the axis of protective case locking rod 14, and protective case locking rod 14 is made to form similar lever construction with hinged shaft 17),
Torsional spring 16 can make 14 rear end of protective case locking rod return after the pressing of push button 13, certainly can also be to be fixed on push button
Pressure spring between 2 lateral wall of 13 bottom walls and lever；It is set with adjustable spring 18 on the lever 2 in sliding chamber 10, is stretched
