The trigger is movably and pivotally connected to the shell and engaged with the block at an engagement point. The extensive element includes a first end connected to the hammer and a second end telescopically connected to the trigger. When the trigger is operated, the hammer is lifted by the extensive element and the engagement point is moved towards the hammer.

Abstract: An apparatus includes a cartridge for storing C-clips. The cartridge includes two lateral members and a lower member extending between the lateral members. The lateral members extend beyond the lower member by at least the thickness of the C-clips so that first one of the C-clips can be moved past the lower member. A saddle is movably connected with the lower member for carrying some of the C-clips. The saddle includes a slope for contact with the first one of the C-clip. Thus, the saddle is moved as the first one of the C-clips is moved. A pocket is connected with the cartridge below the saddle for receiving a pin. A pusher is put movably in the cartridge for pushing the C-clips. An elastic element biases the pusher. A shell receives the cartridge. A hammering device forces the first C-clip onto the pin against the slope.

Abstract: An effort-saving stapler includes a shell device and a triggering device installed to the shell device. The triggering device includes a trigger, an operation element and two bearings. An end of the trigger defines a lever for user to hold, and another end of the trigger includes teeth engaging with the shell device. A pivot pin is adapted for inserting through the trigger, the operation element and the bearings so that the pivot pin can drive the operation element to move in the trigger. A limit pin is adapted for inserting through the trigger and the operation element and abuts with the shell device. The pivot pin is regarded as a fulcrum, while the trigger is pressed, the teeth of trigger engage with the shell device so that the pivot pin quickly moves with the trigger.
