Abstract

A matrix plate and a matrix plate holder for a hand stamp are disclosed, wherein the matrix plate can be easily attached to and detached from the matrix plate holder. The matrix plate includes a mounting element defining a guide, a pair of arc-shaped fitting portions integrally formed on two lateral sides and a front of the guide, wherein each fitting portion defining an engaging tip, and a pair of manipulating wings integrally formed on two lateral sides of the fitting portions. The matrix plate holder includes a main board defining a cutout, two locating blocks located beside the cutout, wherein each locating block defines a locating recess and a connecting structure for connection to a casing of the handle stamp. When the matrix plate and the matrix holder are assembled, the guide is fittingly received in the cutout, the fitting portions are fixedly clamped between the locating blocks and the engaging tips are received in the locating recesses. By exerting a clamping force on the manipulating wings, the engagement between the locating blocks and the arc-shaped fitting portions is released.

Claims

1. A matrix plate and a matrix plate holder for a hand stamp, wherein the matrix plate comprises:

a main plate defining a plurality of recesses at a first side face thereof, said recesses are used to accommodate a matrix;

a flexible mounting element attached to a second side face of the main plate opposite to the first side face, said mounting element comprising;

a guide attached to the main plate;

a pair of arc-shaped fitting portions integrally formed on two lateral sides of the guide, each of said arc-shaped fitting portions defining an engaging tip; and

a pair of manipulating wings integrally formed with the arc-shaped fitting portions; and

the matrix plate holder comprises;

a main board defining a cutout;

two locating blocks located beside the cutout and each defining a locating recess; and

means for connecting the matrix plate holder to a casing of the hand stamp;

whereby,

when the matrix plate and the matrix holder are assembled, the guide is fittingly received in the cutout, the fitting portions are fixedly clamped between the locating blocks and the engaging tips are received in the locating recesses so that the matrix plate and the matrix holder are fixedly connected together, and, by exerting a clamping force on the manipulating wings the engagement between the locating blocks and the arc-shaped fitting portions is released so that the matrix plate is detachable from the matrix plate holder.

2. The matrix plate and matrix plate holder in accordance with claim 1, wherein the matrix plate is formed with two projections on two lateral sides thereof and the matrix plate holder is formed with two mounting slots, and when the matrix plate and matrix holder are assembled, the projections are inserted into the mounting slots.

3. The matrix plate and matrix plate holder in accordance with claim 1, wherein the matrix plate further comprises an auxiliary guide in alignment with the guide and located between the two manipulating wings and when the matrix plate and the matrix plate holder are assembled, the auxiliary guide is also fittingly received in the cutout of the main board of the matrix plate holder.
