Handle slide block mechanism is driven by motor realizes its movement, and sliding block is when stretching and withdrawing two extreme positions, driving link slot
The corresponding two positions of crank are on same straight line on wheel, so the mechanism is without the characteristic suddenly returned, sliding block is in stroke and return
It is slowly to move along a straight line, then the opening and closing speed of binding clip is consistent, to simulate actual operational circumstances in operation.Spring
It is inserted in, is then charged on card slot body in corresponding hole from the head end of spring constraint bolt, the end of spring should be pressed in assembly at this time
On the surface of pressure measuring module, but spring constraint bolt must not stretch out spring end and contact with pressure measuring module.Adjust bolt
The end of spring constraint bolt, the pine that then spring is contacted with pressure sensitive unit are withstood by the screw hole screwed on card slot body
Tight degree is adjusted by adjusting bolt, and the reaction force of spring makes card slot body that can only carry out limited sliding along guide rail,
In test, card slot body will not contact always with pressure sensitive unit.
When carrying out the fatigue property test of surgical clamp, first the end of claw beam seat and pull rod is caught on card slot body and sliding block
In corresponding slot, it then is parked in maximum stroke by can be manually rotated sheave, i.e., crank when binding clip opens maximum angle
Position, rotation adjust bolt and set the pulling force to be applied, and the numerical value of pulling force is shown on control display unit, while being controlled
Setting needs the number recycled that can be in circulation to the weakness such as surgical clamp pull rod and binding clip link mechanism on display unit
Pulling force effect under the mechanical properties such as intensity, rigidity measure and assess.The present apparatus can effectively reduce testing cost and
Subjective factor bring is avoided to influence, test speed is fast and result is accurate, ensure that the safety and validity of product.
The present invention is not limited to the above-described embodiments, makees any variation no matter constituting in its shape or material, all to adopt
It is designed with structure provided by the present invention, is all a kind of deformation of the invention, is considered as within that scope of the present invention.
