したものである。 By the way, one of the gripping parts of the pair of gripping scissors is formed into a plate body and the other part is formed into a flat sheath body with an opening on the side, so that the plate body can be housed in the abdomen of the sheath body when performing a cutting operation. For example, a pair of scissors made in
It is known from Publication No. 36793,
In the present invention, in such gripping scissors, a coil spring is housed in the sheath body to bias both the plate body and the sheath body to open freely, and the biasing elasticity of this spring causes the plate body to close to the sheath body. By providing a stopper on the rear end of the inner edge of the plate located inside the abdomen, which can be hooked inside the rim of the opening in the sheath body when pushed out to the outside of the abdomen. ,
This prevents the creation of a gap between the front sheath body and the externally extruded plate body that would cause a hand or fingers to get caught.

である。 The present invention will be explained below with reference to the embodiment shown in the drawings. Reference numerals 1 and 2 are blade parts pivoted in a cross-shape by a support shaft 3. Behind one blade part 1, which serves as a gripping part, is a wide plate 4.
Further, a flat sheath body 5 is formed behind the other blade part 2 and has an abdomen 5' through which the plate body 4 can be taken in and out from an opening 5a on one side. Reference numeral 6 denotes an engaging tool interposed on the upper edge of the sheath body 5 so as to be able to slide in the front-rear direction.
The hook portion 6' bent forward inside the plate body 4
It is designed so that it can be engaged with a locking part 7 provided in a part of. Reference numeral 8 denotes a coil spring, which is housed in the abdomen 5' of the sheath body 5 by locking both leg ends of the coil portion 8' into the notches 9 and 10 provided on the opposing inner surfaces of the sheath body 5 and the plate body 4, respectively. When the plate 4 is pushed into the abdomen, the spring 8 is compressed to tighten the coil portion 8', and its restoring elasticity causes the plate 4 to be pushed into the abdomen 5'. 11 is a recess formed in the inner edge of the plate 4 in the shape of a notch,
When the plate 4 is pushed into the abdomen 5' against the spring 8, most of the coil spring, including the coil portion 8', enters. 12,
Reference numeral 13 denotes stoppers provided on both sides of the rear end of the plate body 4. By interposing the mouth edge 5b of the rear side of the sheath body 5 between these stoppers, the plate body 4 can be moved in and out of the sheath body 5. The stopper 12 on the inner side is arranged to restrict the range of the mouth edge 5b.
The inner edge 4' of the plate 4 is positioned within the abdomen 5' of the sheath body when the plate body 4 is hooked to the sheath body.

ことになるのである。 In the gripping scissors of the present invention, when both the plate body 4 and the sheath body 5 are grasped against the restoring elasticity of the coil spring 8 from the state shown in FIG. 2 with the blade parts 1 and 2 opened, the plate body 4
The blade rotates around the support shaft 3 and its inner part is pushed into the abdomen 5' of the sheath body 5, thereby closing the blade parts 1 and 2 as shown in FIG. When the external grip force is weakened, the elasticity of the spring 8 causes the stopper 1 provided at the rear end of the inner edge of the plate 4 to move.
The plate body 4
is pushed out of the abdomen 5' of the sheath body 5, and the blade portion can be opened. Note that when both the plate body 4 and the sheath body 5 are grasped, the engagement tool 6
When the blade is moved forward, the hook portion 6' is engaged with the locking portion 7, so that the blade portions 1 and 2 can be kept in a closed state.

するのである。 In this way, according to the present invention, one plate is used as the gripping part of a pair of blade parts whose intersection parts are pivotally connected by a support shaft, while the other plate is used as the grip part of the blade part In the scissors formed as a sheath body having an abdomen in which the sheath body is housed when closed, a coil spring is housed in the abdomen of the sheath body to bias the plate body in a direction to push the plate body out of the abdomen. A stopper is provided at the rear end of the inner edge of the plate located in the abdomen, so that the stopper can be hooked inside the mouth of the opening in the sheath, so that the plate does not respond to the biasing elasticity of the coil spring. Therefore, when the plate is pushed out of the sheath, the stopper provided at the rear end of the inner edge of the plate comes into contact with the rim of the opening in the sheath, and in this abutting state, the plate By locating the inner edge of the sheath inside the abdomen of the sheath, it is possible to eliminate the problem of fingers or other foreign objects getting caught between the sheath and the plate.
