State the mounting groove of the big end of multi-diameter shaft.
As preferred technical solution, the mounting groove is equipped with big for the multi-diameter shaft in the upper surface of the nail kit pedestal
Hold the opening being caught in.
As preferred technical solution, the step surface of the multi-diameter shaft is adjacent to the inner surface of resist-nailed seat upper cover.
As preferred technical solution, the mounting groove includes the guiding extended along the length direction of the nail kit pedestal
Slot, the guide groove and the opening are interconnected, and the front end of the guide groove is equipped with the outer surface for being fitted in the multi-diameter shaft
Arcwall face, it is described opening positioned at the guide groove rear end.
As preferred technical solution, the radius of the arcwall face is equal to the radius of the big end of the multi-diameter shaft.
As preferred technical solution, the both sides of the resist-nailed seat upper cover are respectively equipped with the mounting hole, the mounting hole
It is inside installed with the multi-diameter shaft respectively.
By adopting the above-described technical solution, a kind of resist-nailed seat upper cover pivotal mounting means, for resist-nailed seat upper cover to be turned
Dynamic to be mounted on nail kit pedestal, including shaft, the shaft is that cross section is circular multi-diameter shaft, covers and sets on the resist-nailed seat
There is mounting hole, the small end of the multi-diameter shaft is fixedly mounted in the mounting hole, and the nail kit pedestal is equipped with rotational installation institute
The mounting groove of the big end of multi-diameter shaft is stated, the mounting groove is equipped in the upper surface of the nail kit pedestal and supplies the multi-diameter shaft big end card
The opening entered；The arcwall face that cross section is oriented to front of the slot for circular multi-diameter shaft with being arranged on coordinates, and multi-diameter shaft and arcwall face
Coaxial arrangement, stable connection is reliable, and rotation is smooth, and accuracy is high, therefore jaw closed-gap is stablized, suturing nail molding accuracy
Height, myometrial suture are high-quality.
