Description
Technical field
The invention belongs to herding midwifery technical field of tools, and in particular to a boar obstetric apparatus.
Background technique
When sow produces piggy, it sometimes appear that the case where sow is had difficult labour, especially large-scale pig farm, often go out
The thing that existing piggy fails before being carrying out occurs.The main reason for causing sow to have difficult labour is that the intrauterine of sow has bull piggy will be simultaneously
It is produced, is easy a variety of situations such as transverse presentation in the piggy that producing initial stage causes sow to produce mouth since bull piggy squeezes and occurs, make
Sow is blocked at stillborn foetus and produces mouth, and then sow is caused to be had difficult labour, or because abnormal fetal position, malformation fetus and stillborn foetus are had difficult labour
Etc. factors, can also suppress dead bull piggy behind, eventually cause the death of sow, lose larger.In addition, because sow birth canal is narrow
The factors such as irritability difficult labour caused by narrow property difficult labour, the debilitating difficult labour of force of labor, the property difficult labour of bladder product urine and environmental stimuli, can also make
It has difficult labour at sow.And sow is too obese, birth canal deformity, has disease or depauperation that can also cause to have difficult labour.
For other larger animals, sow birth canal is less than normal, should not use large volume midwifery tool, existing using female
The useful obstetric hook of the common midwifery tool of pig difficult labour and traction rope are only used for sow difficult labour process, and midwifery tool inner end does not have
Operability, injures piglet bigger, or even will cause death, while may damage sow birth canal, it is necessary to the person that has clinical experience
Operation.
Summary of the invention
For existing sow production midwifery tool it is generally existing injure bigger problem to piglet, the present invention provides
A kind of pig obstetric apparatus that can easily control reduces and injures to piglet, reaches smooth midwifery purpose.
The present invention solves scheme used by its technical problem: a boar obstetric apparatus, including handle, core bar and card
Pawl and control mechanism etc., wherein the outer end of core bar connects handle, and the inner end of core bar is fixed with claw mounting base.Claw installation
It is evenly distributed with multiple axial card slots on the outer circumference surface of seat, L-type elastic slice is fixedly installed with respectively in each axial card slot, each
The end of L-type elastic slice is fixed with claw, and multiple claws respectively forwardly tilt tapered.
The handle is combination handle, and control mechanism includes combination handle, linkage spring and adjusting platen.Combination handle packet
Fixed handle and rotatable handle body are included, the two can be rotated and is locked, and the adjusting platen is threaded in core bar inner end
Position and it is located on the screw rod of rear side of claw mounting base, the circumferential edges for adjusting platen can overlay rear side in each L-type elastic slice
Face is connected with linkage spring between the rotatable handle body and adjusting platen.

Slot matching is set with and can rotate but not depart from.The fixed handle contains inner cavity, and fixed handle side wall is provided with to be connected with inner cavity
The radial hole of body, Matching installation has pressing to latch in radial hole, and the inner end for pressing lock is provided with card hole, and a locking spring plate passes through
It wears and is installed in the card hole；Interior pullover side wall is provided with perforative elastic slice locating slot, is arranged in the inner sidewall of the mounting groove
There is locking card slot, the end of the locking spring plate through elastic slice locating slot and is protruded into locking card slot, pressed described in downward push
After pressure lock, the end of locking spring plate is detached from locking card slot.
Claw can not only be structure as a whole, but also can be composite structure, and combination claw includes being sequentially connected to be integrated
Radix unguis, middle elastic slice and pawl head, radix unguis is fixed together with the L-type spring end, pawl head curve inwardly and be arranged convex block and
Anti-skid chequer.
In addition, core bar can pass through the compound rod that transverse pin axle hingedly forms using multistage bar, can be swung between each section of bar
But it is not able to rotate.
Beneficial effects of the present invention:
1. the present invention is controlled multiple claw synchronous (promptly) of core bar inner end using rotation mode and opened, easy to operate
It is convenient.Since twisting resistance is transmitted to internal screw rod from outside using linkage spring by the present invention and adjusts platen, pressed when adjusting
After disk rotational translation, each claw can be oppressed and shunk, and this contraction dynamics is uniformly and stable, control each claw expansion and received
The speed of contracting is gentle but great efforts, crawl effect are very good.
2. pressing lock is arranged to control the lock state of rotatable handle body, when handle revolves in combination handle side in the present invention
Swivel can rotate control rotatable handle body when being pressed, relaxation pressing lock automatically locks control section, it is ensured that linkage portion
Part and each claw all will not self-relaxation, ensure that the reliability of crawl.
3. the present invention is by setting combination claw, each claw can automatically adjust springing amplitude, to avoid making piggy
At damage.
