Abstract

A stamp including a casing, a spring supported actuating member moved in and out of the casing, a stamp plate moved with the casing relative to the actuating member and having a semi-circular gear at one end meshed with a longitudinal rack inside the actuating member, and an ink pad mounted inside the actuating member and disposed in contact with the stamping face of the stamp plate, wherein when the actuating member is pressed on a workpiece, the stamp plate is moved out of the bottom open end of the actuating member and turned through a 180° angle, causing the stamping face to be stamped on the workpiece.

Claims

1. A stamp comprising:

a casing having a top open end, a bottom open end, two through holes bilaterally aligned near the bottom open end, and a transverse insertion slot at a front side thereof near the top open end;

a pivot connected between the through holes of said casing;

an actuating member moved in and out of the bottom open end of said casing, said actuating member comprising a bottom open end, a closed top end, a longitudinal rack on the inside, two longitudinal sliding slots disposed at two opposite lateral sides through which said pivot passes, a stub rod raised from the closed top end, a transverse insertion slot at a front side thereof near the closed top end, and two symmetrical inside flanges bilaterally disposed on the inside adjacent to the closed top end;

a stamp plate turned about said pivot within a 180°

angle and moved in and out of the open bottom end of said actuating member, said stamp plate comprising a semi-circular gear at one end meshed with the longitudinal rack of said actuating member, an axle hole which receives said pivot, and a stamping face made with a mark for stamping;

a top cover covered on the top open end of said casing, said top cover having a bottom coupling flange fitted into the top open end of said casing and a downward stub rod raised from a bottom side thereof;

spring means connected between the stub rod of said actuating member and the stub rod of said top cover to impart a downward pressure to said actuating member; and

an ink pad inserted through the transverse insertion slot of said casing and the transverse insertion slot of said actuating member and held inside said actuating member in contact with the stamping face of said stamp plate by the inside flanges of said actuating member;

wherein when said actuating member is pressed on a workpiece and said casing is pressed down relative to said actuating member, the stamping face of said stamp plate is turned out of the bottom open end of said actuating member and stamped on the workpiece.
