Abstract: A slider base has a slider lock combined therewith so as to be selectively and laterally displaced between a locked position and an unlocked position. The mount has a passage formed therein so as to receive a leg portion of the slider lock, the passage including a locking shoulder formed between an upper compartment and a lower compartment so as to face downward. When the slider is set in the locked position, the leg portion of the slider lock is located under the locking shoulder, and when the slider is set in the unlocked position, the leg portion of the slider lock is located so as to be capable of being inserted into the upper compartment by depressing the mount toward a lower position against an urging force of an urging device.

Abstract: A simple type power stapler has a main body 1, a punching arm 2, a housing frame 3, a hanging means 8 having a hook member 81 engaging with an upper portion of the punching arm 2 and a support portion 80 for supporting a lower portion of the housing frame 3, and a pushing member movable vertically by a motor 5 wherein a pair of support frames 22 are provided above the punching arm so as to accommodate the vertically movable pushing member; the punching arm 2 and the housing frame 3 descend by their own weight to lower their front end side F so that a lower surface 32 of the front end of the housing frame 3 pushes an upper surface of an object to be stapled W when the pushing member is moved downward; and the distance between the hook portions 81 and the support portion 80 of the hanging means 8 is determined to have a dimension which allows the downward movement of the front end side F of the punching arm 2 caused by the movement of the pushing member to its lowest position whereby staple pins P are punched o
