Description
Technical field
The utility model relates to the technical field of PIT label injection device, specifically a kind of fish PIT label injection dress
It sets.
Background technique
PIT label is a kind of electronic tag, is made of the microchip and information transmitting apparatus that have memory, itself does not take
Charged can pass wherein stored information back under dedicated reader excitation.Information in PIT label can be by writing a yard device
Write-in usually has uniqueness, can be used for animal individual identification, dynamic in the wild animal research based on individual identification, laboratory
The fields such as property management reason, domestic animal, poultry and pet animals management, which have, to be more and more widely used.
PIT labelling technique is to carry out fish to mark one of common technology, in fish family breeding, enhancement releasing, comparison
Test etc., which has, to be widely applied.In the research process that family selective breeding applies to genetics-breeding in fish, need to setting up
Each (half sibs) family born of the same parents in individual carry out identity, blood relationship, growthform index etc. and file, by each
Body injects PIT marker, independently files to reach by coding, and construct database during entire family selective breeding.
Presently used PIT label is mainly marked using syringe type, syringe type label have operate it is convenient, quick,
Simple advantage, still, PIT marker are installed on before the injection in injection needle head tube, and marker is injected in fish body abdominal cavity, behaviour
After work, push rod needs are drawn back manually, could be loaded PIT marker again, in family Breeding Process, be needed to be marked
Individual amount it is often larger, continually pull push-rod piston, seriously affects markers work efficiency.
Summary of the invention
The purpose of the utility model is to provide a kind of fish PIT that can improve markers work efficiency to mark injection device.
To achieve the goals above, the technical solution adopted in the utility model are as follows:
A kind of fish PIT marks injection device, including syringe needle, syringe, mandril, piston and mandril handle, after the syringe needle
End is provided with needle holder, and syringe front end is provided with syringe needle connector, and needle holder is connected through a screw thread with syringe needle connector；It is set in needle cylinder wall
It is equipped with and holds handle；Mandril is connect by piston with mandril handle, and piston is mounted in syringe；It is equipped with back in the syringe of syringe needle tip side
Position spring.When injecting PIT marker to fish body, PIT marker is installed in injection needle, hand, which is buckled in, to be held on handle, by mandril
Handle is toward pushing away in syringe, and mandril is by PIT marker being pushed into fish body in syringe needle, piston press return spring, by mandril handle pine
After opening, piston return is not required to artificial pull push-rod piston by return spring, improves markers work efficiency.
It is preferred: spring installation base to be provided in the syringe of syringe needle tip side, it is convex that return spring is sleeved on spring installation
On platform, avoid return spring mobile.
It is preferred: pinhead sleeve being installed on the syringe needle.
It is preferred: the stop collar for preventing piston from skidding off is also equipped in the needle cylinder wall；Mandril and piston are inserted into needle
After in cylinder, stop collar is disposed, prevents spring force from crossing senior general's piston top and goes out.
The fish PIT label injection device structure of the utility model is simple, and return spring is installed in syringe, is infused to fish body
When penetrating PIT marker, PIT marker is installed in injection needle, hand, which is buckled in, to be held on handle, by mandril handle toward pushing away in syringe, is pushed up
PIT marker by being pushed into fish body in syringe needle by bar, and piston press return spring, after mandril handle is unclamped, return spring will
Piston return is not required to artificial pull push-rod piston, improves markers work efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the fish PIT label injection device of the utility model；
