Description
Technical field
This utility model belongs to shears, is meant a kind of separate type shears especially.
Background technology
Two Herba ixeritis debiliss of common shears adopt connecting elements hinged, utilize relatively rotating of Herba ixeritis debilis to finish shear action, can not separate between two Herba ixeritis debiliss, and medical scissors can not separate owing to two Herba ixeritis debiliss, cause bringing very big inconvenience for the disinfection of medical equipment to the junction disinfection difficulty of Herba ixeritis debilis and not thorough; If simultaneously any one in two Herba ixeritis debiliss is damaged, wholely can only scrap shears, cause very big waste.CN88211411U discloses a kind of separate type multifunctional shears, adopt pin and gap slot to articulate cooperation, this technology exists two Herba ixeritis debiliss and repeatedly cooperatively interacts after the dismounting not closely, and the segregative problem of Herba ixeritis debilis brings problems such as very big inconvenience for medical accurate operation.
Summary of the invention
The purpose of this utility model is to provide a kind of two Herba ixeritis debiliss can separate freely, and compact again in use separate type shears is to overcome the deficiency of prior art simultaneously.
Overall structure of the present utility model is:
A kind of separate type shears is made up of two Herba ixeritis debiliss 1,2, and Herba ixeritis debilis 1 is provided with bearing pin 3, and Herba ixeritis debilis 2 surfaces offer the bearing pin 3 corresponding through holes 6 with Herba ixeritis debilis 1, and bearing pin 3 is rotatably assorted with through hole 6, and bearing pin 3 tops are provided with positioning head 8; Through hole 6 one sides of Herba ixeritis debilis 2 offer gap slot 4, the A/F of gap slot 4 is between the width of the diameter of bearing pin 3 and positioning head 8, that gap slot 4 lower surfaces offer is consistent with gap slot 4 opening directions, convenient and shallow groove 5 that Herba ixeritis debilis 1 is installed, shallow groove 5 other ends are cecum, and positioning head 8 lower surfaces and through hole 6 inner surfacies are that tight fit is rotated assembling.
Concrete structure of the present utility model is:
The cross section of shallow groove 5 is rectangle, trapezoidal or wedge shape.Bearing pin 3 is screw or bolt, and the bottom of screw or bolt and Herba ixeritis debilis 1 adopts fixing assembling or screw thread tight fit, and positioning head 8 is the nut with the top secure fit of screw or bolt.
The degree of depth of shallow groove 5 is not less than its opening part to the distance between the bearing pin 3.
Herba ixeritis debilis 1 is provided with a wedge shape or class wedge shape boss 7 with at least one side surface root of the cooperation place of Herba ixeritis debilis 2.
Positioning head 8 is a kind of in truncated cone-shaped, tubaeform, the cylindrical or spherical crown shape.
The inner surface of through hole 6 offers and the corresponding plane of rotation of positioning head 8 lower surfaces.
The beneficial effect that this utility model is obtained is:
Overall construction design of the present utility model is reasonable, and part replacement is convenient, sterilizes up hill and dale respectively after can splitting it when sterilizing as medical equipment, and assembling finishes back two Herba ixeritis debiliss cooperation closely, is difficult for getting loose, and is beneficial to accurate medical operation.
