Angle between tractive unit is 15 ° -30 °, while piercing portion is controlled with respect to the angle that tractive unit turns forward at 13 ° -15 °,
Allow and be formed by the more convenient skin tangled on the outside of neck in space between piercing portion, interconnecting piece and tractive unit, leads
Pull-up with shape flesh, visual area exposure is big, provides conveniently for operation.
3, the caliber in piercing portion becomes larger from its top to bottom end, can reduce resistance when skin penetrating, reduces wound.
4, the minimum pipe in piercing portion is 0.8mm-1.2mm, and the maximum caliber in piercing portion is 1.8mm-2.2mm, is being guaranteed
It while drag hook has sufficient intensity, may make the caliber of drag hook sufficiently fine, be more easier so that puncturing, while reducing to visual area
Block, exposure effect is good.
5, piercing portion, interconnecting piece and tractive unit are integrally formed, the largest tube of the caliber and piercing portion of interconnecting piece and tractive unit
Diameter is equal, so that the overall structure of drag hook is smooth, can reduce wound when skin penetrating.
6, the bottom of interconnecting piece offers drainage hole, tissue fluid, the blood being conveniently discharged into drag hook.
7, drag hook is crome metal material, and chromium matter is extremely hard, corrosion-resistant, using drag hook made of crome metal, it is ensured that higher
Use intensity, indeformable guarantee traction dynamics in use process, while corrosion-resistant, long service life.
