れている。2. Description of the Related Art Conventionally, the cutting edge portion is housed in the palm of a hand, and a pair of grip portions urged in the opening direction are closed by gripping the hand, and the scissors blade edge of the opening / closing tip portion is closed. The so-called hand-held scissors that polymerize and cut an object to be cut are often used.
【0003】このような握り鋏において、常時働いてい
る付勢力により開き角(刃先の間隔)を常に一定に保持
する開き角保持機構を有するものがある。Some of such gripping scissors have an opening angle holding mechanism for always holding the opening angle (distance between the cutting edges) constant by the urging force which is constantly applied.

ガイドピンを設けた構成である。This opening angle holding mechanism will be described, for example, on the basis of the type shown in the drawings of the present embodiment. Scissors blade edges are formed at the opening and closing tip of the handle, and a polymerized portion that overlaps with each other is projected on the inside of each handle, and a guide hole is formed in at least one of the polymerized portions,
A guide pin slidably engaged with the guide hole is provided in the other overlapping portion.
【0005】従って、常態では前記付勢力によりガイド
ピンの係合外面がガイド孔の内端縁に当接係止する。Therefore, in the normal state, the engaging outer surface of the guide pin abuts against and engages with the inner end edge of the guide hole by the urging force.

得る構成である。Therefore, in a normal state, the scissor blade edges are held at a pair of opening angles, and when the hands are held and the grip portions are pressed inward, the guide pin and the guide pin guide the guide pin to the other inner end of the guide hole. The scissors blade is of a composition that can be polymerized until it hits the edge.

【発明が解決しようとする課題】従来このような握り鋏
があるが、保持される鋏刃縁の開き角(刃先の開き間
隔)を調整したい場合がしばしばある。Conventionally, there are such gripping scissors, but it is often desired to adjust the opening angle of the scissors blade edge to be held (opening interval of blade edges).
【0008】例えば、細かい切断作業や正確な切断作業
をする場合には、開き角が小さい程切断位置が位置決め
し易く、わずかな部分のみを正確に切断し易くなり非常
に作業し易い。For example, when performing a fine cutting operation or an accurate cutting operation, the smaller the opening angle, the easier it is to position the cutting position, and it becomes easier to accurately cut only a small portion, which is extremely easy to work.
【0009】逆に大まかで大きな切断作業をする場合に
は、開き角が大きい程非常に作業が速い。On the contrary, when performing a rough and large cutting operation, the larger the opening angle, the faster the work.
