ABSTRACT:
A pen-shaped tire pressure gauge includes a hollow body having one end formed with a pressure measuring head and the other end formed with an open end and its interior formed with an accommodating space. The pressure measuring head is formed with an air intake passageway communicating with the accommodating space and has its outside fitted with a metallic protecting ring. A scale rod is received in a coiled spring and they both are positioned in the hollow body. The coiled spring is fitted with a piston at the upper end, and the scale rod is fitted with a stop ring and a stop sleeve around the lower end. A fixing cap is combined with the open end to prevent the components inside the hollow body from dropping out, strengthening the pressure measuring head to prolong its service life.
