Abstract (en)
A laborsaving hole puncher (1, 2, 3, 4, 5) has a base (10, 10a, 10b), at least one cutter (15, 15a), a top cover (40, 40a, 40b) and at least one articulated linkage (14, 60, 160). The base (10, 10a, 10b) has at least one bracket (13, 13a, 13b). The least one cutter (15, 15a) slidably is mounted respectively on the at least one bracket (13, 13a, 13b). The top cover (40, 40a, 40b) is mounted pivotally on the at least one bracket (13, 13a, 13b). The least one articulated linkage (14, 60, 160) connects respectively to the at least one bracket (13, 13a, 13b), the at least one cutter (15, 15a) and the top cover (40, 40a, 40b). The at least one articulated linkage (14, 60, 160) makes people easily conveniently use the laborsaving hole puncher (1, 2, 3, 4, 5) without strenuous effort.
