The present invention can be selected as clamp or scissors according to actual use demand and use, when needing as clamp in use,
First rotating shaft 7 is pressed, spring 13 is compressed, and flange 15 is mobile to 5 direction of the first blade therewith and enters in flange sliding slot 16, to
Right sliding first rotating shaft 7, thrust block 12 and spring 13 move, when first rotating shaft 7 slides into the right end of first sliding groove 8,
First rotating shaft 7 is unclamped, under the elastic force effect of spring 13, flange 15 is pushed into the counterbore 17 of 16 right end of flange sliding slot, and first
The position of shaft 7 is locked；It according to same operation, presses the second shaft 9 and slides to the right, when the second shaft 9 slides into the
When the right end of two sliding slots 10, the second shaft 9 is unclamped, it is right that flange 15 corresponding with the second shaft 9 enters corresponding flange sliding slot 16
In the counterbore 17 at end, the position of the second shaft 9 is locked；Meanwhile in above-mentioned adjustment process, the hinge of cutter 5 and bottom knife 6
Spindle crosses to the right the articulated shaft of upper clamp 1 Yu lower clamp 2, and cutter 5 is completely disposed inside upper clamp 1, and bottom knife 6 is set completely
Inside lower clamp 2, cutter 5 and bottom knife 6 will not enter on the inside of jaw in jaw closing course, because cutting without generating
The effect of cutting, upper clamp 1 are directly contacted with lower clamp 2, realize that the clamping to article operates.
When needing as scissors in use, pressing first rotating shaft 7 and the second shaft 9 by above-mentioned same method and sliding to the left
It is dynamic, first rotating shaft 7,15 quilt of flange corresponding with first rotating shaft 7 are unclamped when first rotating shaft 7 slides into the left end of first sliding groove 8
Corresponding spring 13 is pushed into the counterbore 17 of corresponding 16 left end of flange sliding slot, and the position of first rotating shaft 7 is locked again；When
Two shafts 9 unclamp the second shaft 9 when sliding into the left end of second sliding slot 10, corresponding with the corresponding flange 15 of the second shaft 9
Spring 13 is pushed into the counterbore 17 of corresponding 16 left end of flange sliding slot, and the position of the second shaft 9 is locked again；Meanwhile upper
It states in adjustment process, the articulated shaft of cutter 5 and bottom knife 6 crosses the articulated shaft of upper clamp 1 and lower clamp 2 to the left and is placed in pincers
On the inside of mouthful, in jaw closing course, cutter 5 and the angle of bottom knife 6 constantly become smaller, to realize that the shearing to article is grasped
Make.
Structure of the invention is exquisite, easy to use, integrates the function of clamp and scissors, only need to be by changing first rotating shaft
The switching of two kinds of functions can be realized with the position of the second shaft, and clamping with shearing manipulation is controlled by lever, is not needed
Other control mechanisms ensure that convenience when medical staff uses, can also avoid clamp and scissors to a certain extent
The case where taking by mistake reduces issuable security risk；It meanwhile when not in use, can be completely hidden by cutter and bottom knife
Hiding, can be effectively reduced take in transportational process because of blade accidental exposure bring security risk.
