A stapler is an essential tool for woodworkers, the stapler connects different wood materials together. Users can discharge the staples only by pressing the pressing member. However, inventors of the conventional stapler only focus on the effort-saving mechanism of the stapler, but ignore configuration structures between a magazine assembly and staples effect a stability of discharging, and further effect the quality of assembled products.
The present invention is, therefore, arisen to obviate or at least mitigate the above mentioned disadvantages.
The main object of the present invention is to provide a magazine assembly and a staple including the same which is applied for different staples (such as T-shaped staples, U-shaped staples or reverse U-shaped staples), and is adapted for the T-shaped staples with different lengths to abut against a base exactly to improve the quality of discharging the staples.
To achieve the above and other objects, the magazine assembly includes a base and a rail assembly. The base has a first end portion and a second end portion. A direction from the second end portion toward the first end portion is defined as a first direction. The rail assembly is disposed on the base and adapted for a staple unit to movably abut thereagainst along the first direction. The rail assembly includes a first rail and a second rail which are separate. A first side wall of the first rail has at least one guiding portion extending in the first direction. Each guiding portion is adapted for a head of a T-shaped staple to slidably engage therewith along the first direction. The second rail is adapted for a U-shaped staple to abut thereagainst.
To achieve the above and other objects, further includes the stapler includes a main body, a shell and an impact plate. The main body includes a pressing member. A shell has a receive portion, the magazine assembly and the shell define a discharge opening therebetween. The discharge opening is for corresponding by the staple unit, the pressing member and the impact plate drive mutually. When the pressing member is moved relative to the shell, the pressing member drives the impact plate to move toward an opening of the discharge opening to discharge part of the staple unit.
