Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, a kind of breastbone closing fixer erecting tools is provided, it can position with fastening breastbone closing fixer, making breastbone closing fixer balancedly give breastbone fixes, and degree of tightness is controlled, be easy to operate fixing-stable.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of breastbone closing fixer erecting tools, it comprises tooth bar and two drawing arms, two drawing arms all are sleeved on the tooth bar, be provided with on each drawing arm and can limit the non-return mechanism that drawing arm moves relative to tooth bar, and be equipped with on one of them drawing arm and drive its driving mechanism that moves relative to tooth bar, the bottom of each drawing arm is equipped with one group of positioning boss and trip bolt that can match with breastbone closing fixer.
Further, described driving mechanism comprises knob and gear, knob rotatably is inserted on the drawing arm that driving mechanism is installed, and gear set is on knob, and wheel and rack is meshed in order to utilize the relative tooth bar move left and right of this drawing arm of gear driven during rotary knob.
Further, described non-return mechanism comprises non-return clamp and torsion spring, the non-return clamp is hinged on the corresponding drawing arm, one end of torsion spring is connected on the non-return clamp, the other end is connected on the corresponding drawing arm, one end of non-return clamp be provided with can with the hook part of tooth bar groove clamping, the other end of non-return clamp is provided with button breaks away from hook part and tooth bar groove in order to press the button.
Further, described positioning boss and pass drawing arm bottom trip bolt the ailhead setting at grade, and positioning boss is positioned at the inboard of ailhead.
Further, described positioning boss is square structure.
After having adopted technique scheme, the positioning boss of two drawing arms of the present invention inserts respectively in the locating hole of male fixture and female fixture, the trip bolt of two drawing arms is screwed into respectively in the screw of male fixture and female fixture, pass through driving mechanism, rotary knob namely, driven gear is mobile at tooth bar, thereby one of them drawing arm is moved with respect to tooth bar, thereby can control the distance between the male fixture of breastbone closing fixer and the female fixture, the width of breastbone is opened in adjusting, it is mobile at tooth bar that non-return mechanism can limit corresponding drawing arm, thereby guarantee the fixedly reliability and stability of breastbone of breastbone closing fixer, press the button, hook part and tooth bar groove are broken away from, two drawing arms can move relative to tooth bar again, two drawing arms are adjusted to suitable position on the tooth bar, realize that degree of tightness is controlled, after breastbone closing fixer locking, can screw out trip bolt, the present invention is separated with breastbone closing fixer.
