One word hole moves to the downside of arc-shaped guide rail, so as to release the fixation to arc-shaped guide rail, while unclamping the wedge shape of the left and right sides
Block can make wedge block is mobile to reset under the action of the first spring force, and then foot is placed on cushion by patient, medical care
Personnel again swing arc-shaped guide rail to the right, the wedge block of the left and right sides can be made mutually to draw close by a word hole, the first spring
It compresses therewith, the wedge block of the left and right sides can so be made to be located at the upside of snap-gauge, and under the action of the first spring, can make
Mobile reset of the wedge block of the left and right sides fixes arc-shaped guide rail, can so prevent when taking nail to patient foot, arc is led
Rail shakes takes nail to bring obstruction to medical staff.
When needing mobile mounting plate, medical staff, which presses down on baton round, moves down inserted link, and second spring is therewith
Compression, inserted link, which moves down, drives kelly to remove in latch, can so release the fixation to mounting plate, and subsequent medical staff moves
Dynamic mounting plate, mounting plate can make kelly be moved to suitable position in the second through-hole by inserted link, and then medical staff unclamps
Baton round can be such that kelly is caught in latch upwards, can so consolidate to mounting plate under the action of second spring elastic force
It is fixed, so as to facilitate medical staff to carry out mobile limit to mounting plate.
Blocking for the left and right sides can be made to contact always with screwdriver by the elastic force of third spring, and can be to screwdriver
It is limited, can so be prevented when taking nail to patient, screwdriver deviates to taking nail to bring obstruction.
The present invention has the advantage that the present invention can be such that screwdriver is moved to properly by mobile sliding and fixed device
Position, then medical staff carries out patient by screwdriver to take nail, is so not required to medical staff and holds screwdriver to patient's progress
Nail is taken, so as to reduce the labor intensity of medical staff, and can be improved and take nail efficiency；Blocking device can be to arc-shaped guide rail
Fixed, so as to prevent when taking nail to patient foot, arc-shaped guide rail shakes takes nail to bring obstruction to medical staff；Pass through
The elastic force of three springs can be such that blocking for the left and right sides contacts always with screwdriver, can so prevent when taking nail to patient,
Screwdriver deviates to taking nail to bring obstruction.
