携帯型切断機
Document Type and Number:
Japanese Patent JP6857536
Kind Code:
B2
Abstract:
The hand-held cutter 1 includes: a cutting blade 3 which is configured to rotate about a rotation shaft 23a to cut a target; a cutter body 2 which rotatably supports the cutting blade 3; a protection cover 4 which covers a portion of the cutting blade 3 and is rotatable about the rotation shaft 23a; a pressing mechanism 5 which is configured to move toward the protection cover 4 to press a guide plate 44 onto a support plate 26 so as to impose and maintain restrictions on rotation of the protection cover 4; and a torsion coil spring 7 exerting a biasing force to move the pressing mechanism 5 toward the protection cover 4. The hand-held cutter 1 is configured such that moving the pressing mechanism 5, against the biasing force of the torsion coil spring 7, away from the protection cover 4 removes restrictions on the rotation of the protection cover 4.
