FIELD OF THE INVENTION
The present invention relates to a marking structure for a tool surface which has variable color appearance so that a user distinguishes a size of a tool clearly.
DESCRIPTION OF THE PRIOR ART
As illustrated in FIGS. 1 and 2, a conventional marking structure contains a marking portion 12 laser marked on a tool surface 11, wherein a color of the marking portion 12 is different from that of the tool surface 11 so that the user distinguishes a size of a tool 10.
However, the color of the marking portion 12 is slightly different from that of the tool surface 11, so when the user views the marking structure at different angles, he/she cannot distinguish the size of the tool 10 clearly.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a marking structure for a tool surface which has variable color appearance so that a user distinguishes a size of a tool clearly.
To obtain the above objective, a marking structure for a tool surface provided by the present invention contains: a marking area laser marked on a tool surface, a color zone pad printed or screen printed a color material in the marking area. The color zone is overlapped with the printing area.
In another embodiment, a marking structure for a tool surface of a tool contains a color zone formed by printing a color material on the tool surface and a marking area connecting with the color zone.
The color zone includes any one of a pattern, at least one number, at least one letter, a combination of the pattern and the at least one number, and a combination of the at least one letter and the pattern.
Preferably, a height of the marking area is equal to a height of the tool surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 3, 5 and 7, a marking structure for a tool surface 21 of a tool 20 according to a first embodiment of the present invention comprises: a marking area 23 laser marked on the tool surface 21, a color zone 24 pad printed or screen printed a color material in the marking area 23, wherein the color zone 24 is overlapped with the marking area 23 and includes any one of a pattern, at least one number, and a pattern and at least one number. Preferably, a height of the marking area 23 is equal to a height of the tool surface 21.
Referring further to FIGS. 4, 5, 6 and 8, a marking structure for a tool surface 21 of a tool 20 according to a second embodiment of the present invention comprises: a color zone 24 formed by printing a color material on the tool surface 21 and a marking area 23. The color zone 24 includes any one of a pattern, at least one number, and a pattern and at least one number which is formed by removing any one of a pattern region, at least one number region, and a pattern region and at least one number region in a laser marking manner. Preferably, a height of the marking area 23 is equal to a height of the tool surface 21.
In addition, any one of the pattern, the at least one number, and the pattern and the at least one number of the color zone 24 is formed by removing a remove portion beyond any one of the pattern region, the at least one number region, and the pattern region and the at least one number region in a laser marking manner, such that the remove portion forms in the marking area 23 which connects with the color zone 24.
As shown in FIGS. 9 and 10, the color zone 24 includes a plurality of color layers, and each color layer has a varying color so that the marking structure has variable color appearance. Preferably, the color zone 24 also includes at least one letter or the at least one letter and the pattern.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
