  • Patent number: 7757923
    Abstract: A stapler has a supporting base, a magazine assembly, a trigger assembly and a leg-flatting device. The trigger assembly has a trigger lever and a pushing element. The pushing element is mounted pivotally on the trigger lever with a pivot and has two pushing arms extending toward the supporting base. The leg-flatting device is mounted on the supporting base and has a sliding base, a moving base and an anvil element. The sliding base is slidably mounted on the supporting base and has a pushed segment corresponding to and selectively pushed by the pushing arms. The moving base is selectively blocked by the sliding base to keep the moving base from moving downwardly before the sliding base sliding relative to the supporting base and has an elongated hole. The anvil element is mounted in the elongated hole in the moving base.
    Type: Grant

  • Patent number: 7721636
    Abstract: A hole puncher has a base, multiple cutter brackets, multiple cutters, multiple springs, a linkage, an activating member and a handle. The base has two ends. The cutter brackets are mounted on the base. The cutters are mounted slidably through the cutter brackets. The linkage connects pivotally to one end of the base. The activating member connects pivotally to the linkage. The handle connects pivotally to the other end of the base and selectively pivots the linkage down. With the linkage and the activating member, the hole punch is effort-saving.

  • Patent number: 7621432
    Abstract: A stapler has a center of gravity and has a base assembly, a magazine assembly and a trigger assembly. The magazine assembly connects to the base assembly and has a cap. The trigger assembly connects to the base assembly and has a trigger lever and a limiting lever. The limiting lever prevents the trigger lever and the cap from pivoting excessively to keep the center of gravity of the stapler over the base assembly so that refilling the stapler is convenient.
