A straight stapling and cutting device, comprising: an upper clamp (1), a lower clamp (5), a closing handle (11), a staple anvil (3), and a staple chamber (7). Provided inside of the staple chamber (7) are a staple-pushing rod (13) and a cutter-pushing rod (15) that can simultaneously move along the axis of the stapling and cutting device. One end of the staple-pushing rod (13) and one end of the cutter-pushing rod (15) are disposed on a sliding block (17). Provided on the sliding block (17) is a toggle base (21) in a relatively fixed position with respect to the sliding block (17). At least one toggle (29) is pivotally installed on the toggle base (21). The toggle (29) can switch between the state of having the operation surface thereof perpendicular to the axis of the stapling and cutting device and the state of having the operation surface thereof parallel to the axis of the stapling and cutting device. The toggle (29) of the straight stapling and cutting device opens and extends to the outside of the clamps to satisfy the requirements of specific operations. The toggle (29) closes and is in close contact to the clamps so as to reduce the total volume of the stapling and cutting device and thus to reduce the packaging and transportation cost. Upon completion of an operation, the toggle is moved backward and closed so as to indicate the completion of the operation. The toggle (29) is simple in structure, convenient to assemble, and fairly practical.
