Lower free to adjust, the bottom of the connection shaft is fixed with handle, and the junction for strutting tooth and positioning tooth is fixed with soft
The transition pad of softwood matter.
Further, in order to which to adapt to the different edges of a knife by the adjusting of itself, the angle between the installing handle can
It is freely adjusted under the promotion of adjusting screw rod.
Further, the contraction of the edge of a knife reduces the angle between two installing handles in order to prevent, and the support spring can be right
The installing handle of two sides applies outside elastic force.
Further, it carries out disinfection in order to facilitate the later period, the support shank can freely dismantle installation from installing handle.
Further, in order to prevent support when occur sliding reduce support effect, it is described strut tooth and positioning tooth all at
It arc and is mutually perpendicular to therebetween.
Further, in order to avoid damage struts the tissue such as position fat, muscle, described strut is fixed on tooth outer end face
One layer of protective pad.
Further, it is held in order to facilitate user of service, the arc that indent is fixed on the lateral surface of the installing handle is held
Hold block.
Further, fixed on the two sides of the fixed link in order to enable the more fastening that installing handle is connected with support shank
There is the locking reed for capableing of deformation.
Further, in order to enable the junction transition of the two is smoother, the junction for strutting tooth and positioning tooth
It is fixed with the transition pad of soft material.
The beneficial effects of the present invention are: this to strut fixer structure connection compact, using simple, design rationally, installing handle
Between angle can freely be adjusted under the promotion of adjusting screw rod, can accomplish to support the edge of a knife at any angle, Ke Yitong
The adjusting of itself is crossed to adapt to the different edges of a knife, support spring can apply outside elastic force to the installing handle of two sides, can be to peace
Hilt provides outside support force, prevents the contraction of the edge of a knife from reducing the angle between two installing handles, to play good branch
Effect is supportted, support shank can freely dismantle installation from installing handle, be able to carry out free dismantling, the later period be facilitated to carry out disinfection,
It struts tooth and positioning tooth all cambers and is mutually perpendicular to and the skin shape of edge of a knife two sides matches therebetween, in support
Edge of a knife two sides can be effectively stuck in, prevents that sliding reduction support effect occurs in support, struts and be fixed on tooth outer end face
One layer of protective pad, plays a protective role to tissue, avoids damage to strut the tissue such as position fat, muscle, the lateral surface of installing handle
On be fixed with the arc of indent and hold block, be easy to use personnel to hold, will not slide in the hand, it is solid on the two sides of fixed link
Surely there is the locking reed for capableing of deformation, so that the more fastening that installing handle is connected with support shank, it is not easy to relatively move, support
The junction of tooth punching and positioning tooth is fixed with the transition pad of soft material, so that the junction transition of the two is smoother, support
When be not easy injury tissue.
