Abstract

An embossing seal has a base, a die assembly disposed in the base, a driven shaft assembly movably disposed in the base, and a pressing handle pivotally disposed on the base for driving the driven shaft assembly. The driven shaft assembly has a lower shaft, an upper shaft, a cushion spring, and a restoring spring. The lower shaft is movably disposed in a shaft tube of the base. The upper shaft is movably disposed in the lower shaft. The cushion spring and the restoring spring are coaxially disposed around the upper shaft. Two ends of the cushion spring respectively abut against the upper shaft and the lower shaft. Two ends of the restoring spring respectively abut against the upper shaft and the shaft tube. Structure of the base and structure of the driven shaft assembly are simplified. The embossing seal is restored accurately and quickly.

An embossing seal comprising:

a base having
a carrying member having a carrying platform formed on the carrying member;
an embossing space formed in the base and located above the carrying platform;
and
an operating member formed on the carrying member and having
a shaft tube formed on the operating member, and having a shaft hole formed through the shaft tube and communicating with the embossing space of the base, wherein the embossing space of the base is located between the shaft tube and the carrying member;
a die assembly disposed in the base and having
a lower die disposed on the carrying platform and located in the embossing space of the base;
an upper die located in the embossing space of the base and facing the lower die;
and
an elastic part connected to the lower die and the upper die;
a driven shaft assembly movably disposed in the operating member of the base and having
a lower shaft disposed in the shaft hole of the shaft tube, being moveable up and down relative to the base, and having a top end and a central hole formed through the lower shaft;
an upper shaft disposed in the central hole of the lower shaft, being moveable up and down relative to the lower shaft, and having
a top end of the upper shaft protruding out of the top end of the lower shaft;
and
an active end portion formed on the top end of the upper shaft;
a cushion spring disposed around the upper shaft and having two ends respectively abutting against the active end portion of the upper shaft and the top end of the lower shaft;
a restoring spring disposed around the upper shaft, located around the cushion spring, and having two ends respectively abutting against the active end portion of the upper shaft and the top end of the shaft tube, wherein the driven shaft assembly is able to drive the upper die to move relative to the lower die;
and
a pressing handle pivotally disposed on the operating member of the base, and having
a bottom end being adjacent to the shaft tube;
a pushing portion formed adjacent to the bottom end of the pressing handle and abutting against the active end portion of the upper shaft.
