Referring to fig. 1 to 4, a detachable micro-scissors according to an embodiment is shown, wherein the detachable micro-scissors include a scissors main body 1, a sliding member 2 having one end movably connected to the scissors main body 1, and a rotating member 3 having one end penetrating the scissors main body 1 and detachably embedded in the sliding member 2, and the rotating member 3 performs a reciprocating swing motion around the scissors main body 1 with a position penetrating the scissors main body 1 as a center. The microscissors 4 are mounted at the same ends of the scissors main body 1 and the sliding part 2, and the rotating part 3 controls the sliding part 2 and the scissors main body 1 to slide in a reciprocating manner in a reciprocating swinging process, so that the microscissors 4 mounted at the same ends of the scissors main body 1 and the sliding part 2 can move (namely the cutting edges of the two blades of the microscissors 4 can be closed or separated to realize a cutting function).

In this embodiment, the microscissors 4 are mounted on the head of the scissors main body 1, the first blades 41 of the microscissors 4 are further mounted on the head of the scissors main body 1, the first finger ring 11 for inserting a finger is formed at the tail of the scissors main body 1, the tail of the scissors main body 1 is bent to the approximate center to form the handle 12, so as to be matched with the rotating part 3, and the overall external contour of the microscissors is shaped like a pistol, so that an operator can use the microscissors conveniently. The scissors main body 1 is provided with an installation opening 5 penetrating through the scissors main body 1 at a position close to the center, and a limit groove 6 is formed at a position of the side wall of the scissors main body 1 where the installation opening 5 is located. The slider 2 is provided with a caulking groove 21 at an end opposite to the end connected to the scissors main body 1. The head of the rotating member 3 is provided with an embedding head 31 with the contour being consistent with the shape of the embedding groove 21, the side wall of the rotating member 3 near the embedding head 31 is provided with a convex column 32, and the tail of the rotating member 3 is provided with a second finger ring 33 for inserting a finger.

The embedded head 31 of the rotating part 3 penetrates through the mounting opening 5 and is embedded in the embedded groove 21, the convex column 32 is located in the limiting groove 6, the rotating part 3 is embedded behind the sliding part 2, meanwhile, the sliding part 2 and the scissors main body 1 are basically close to and attached to each other through the limiting of the convex column 32 in the limiting groove 6, only a certain gap 20 is reserved, and certainly, the sliding part and the scissors main body 1 can be completely attached to each other without the gap 20. The rotating part 3 performs reciprocating swing motion around the scissors main body 1 by taking the convex column 32 as a center, and the second finger ring 33 is close to or far away from the first finger ring 11 in the reciprocating swing process.

In this embodiment, the contour of the caulking groove 21 is a semicircular shape with a major arc length, and the outer contour of the same insert head 31 of the rotating member 3 is also a semicircular shape with a major arc length, that is, the whole outer shape of the caulking groove 21 is a circular structure with an opening at the lower part, and the major arc structure enables the insert head 31 to be firmly installed in the caulking groove 21, and will not fall out of the caulking groove 21 in the using process.

In the present embodiment, the pair of microscissors 4 includes a first blade 41 integrally formed with the head of the scissors main body 1 (of course, in other embodiments, the first blade 41 does not have to be a structure integrally formed with the scissors main body 1, but may be a connection structure in a detachable manner via another connection member), and a second blade 42 pivotably connected to the first blade 41 via a rotation shaft (not shown), respectively, the second blade 42 being pivotally connected to the slider 2 (i.e., also connected to the slider 2 via the rotation shaft, but not shown), and the slider 2 controlling the second blade 42 to close or separate from the first blade 41 during the sliding back and forth relative to the scissors main body 1.

In the embodiment, the limiting boss 14 protrudes outwards from the surface of the scissors main body 1 opposite to the sliding part 2, the limiting step 22 matched with the limiting boss 14 in structure is inwards recessed from the surface of the sliding part 2 opposite to the scissors main body 1, and when the limiting step 22 is contacted with the limiting boss 14, the second blade 42 is closed with the first blade 41. Thus, when the limit step 22 is away from the limit boss 14, the second blade 42 is separated from the first blade 41, i.e., the scissor head is opened.

In the present embodiment, the slider 2 has a positioning block 23, and the scissors main body 1 has a positioning groove 13 at a position corresponding to the positioning block 23. The main functions of the positioning block 23 and the positioning groove 13 are to accurately position the sliding member 2 when approaching the scissors main body 1, so as to avoid the micro scissors from being damaged by misoperation such as misloading.

In this embodiment, the scissors further include a lock catch 7 rotatably mounted on the scissors main body 1 through a pin 8, the lock catch 7 has a bent edge 9, the lock catch 7 is rotatably limited through the bent edge 9 in the rotating process, and when the lock catch 7 is located at the rotation limiting position, the lock catch 7 shields a gap 20 between the scissors main body 1 and the sliding member 2. The lock catch 7 is mainly used for limiting the sliding part 2 and the scissors main body 1 in the horizontal direction and preventing the sliding part 2 and the scissors main body 1 from being dislocated in the working process to influence the operation process.

To sum up, the utility model discloses a to micro-scissors make the detachable structure, through set up the installing port in the scissors main part, supply to rotate the piece and insert and connect to the slider, still can realize the function of micro-scissors itself after the installation is accomplished, when needing cleaning and disinfection after follow-up operation finishes simultaneously, only need to rotate the piece respectively with slider, the separation of scissors main part can wash, realized that the part that will micro-scissors is torn open and more easy cleaning and disinfection alone, will micro-scissors spot etc. remain thoroughly to clear away totally, further improved operation health security.

The above is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, and it should be appreciated by those skilled in the art that various equivalent substitutions and obvious changes made in the specification and drawings should be included within the scope of the present invention.
