Tile cutting device provided with auxiliary base

A tile cutting device is composed of a base, two support frames, two guide rods, a slide seat, a cutting tool seat, a cutting tool, and a grip rod. The base is provided at one longitudinal side thereof with an auxiliary base which is detachably fastened therewith such that the upper surface of the auxiliary base is flush with a tile placing surface of the base, and that the auxiliary base gives an added width to the base to accommodate a large tile to be worked on by the tile cutting device. The auxiliary base can be unfastened and kept in the underside of the base.

FIELD OF THE INVENTION 
The present invention relates generally to a tile cutting device, and more 
particularly to a tile cutting device which is provided with an auxiliary 
base for giving an added width to the base of the tile cutting device. 
BACKGROUND OF THE INVENTION 
As shown in FIG. 1, a tile cutter 10 of the prior art comprises a 
rectangular base 11, two support frames 12, two guide rods 13, a slide 
seat 14, a cutting tool seat 15, a circular cutting tool 16, a press plate 
17, and a grip rod 18. 
The two support frames 12 are mounted on both longitudinal ends of the base 
11. The two guide rods 13 are fastened with the two support frames 12 such 
that the two guide rods 13 are parallel to each other, and that the slide 
seat 14 is fastened pivotally with the two guide rods 13. The cutting tool 
seat 15 is fastened pivotally with the slide seat 14 such that the cutting 
tool seat 15 is located between the two guide rods 13. The circular 
cutting tool 16 is fastened pivotally with the bottom of the cutting tool 
seat 15. The press plate 17 is fastened with the bottom of the cutting 
tool seat 15 such that the press plate 17 is located behind the circular 
cutting tool 16. The grip rod 18 is fastened with the cutting tool seat 15 
for pushing the cutting tool seat 15 to move along the guide rods 13. 
The tile cutter 10 of the prior art is in not effective design in that it 
has a long base 11 and two long guide rods 13, which complicate the 
storing and the packaging of the tile cutter 10. In addition, the base 11 
has a width which is insufficient to support securely a large tile to be 
worked on by the tile cutter 10, especially at such time when the cutting 
line is located away from the center of the large tile. 
SUMMARY OF THE INVENTION 
It is therefore the primary objective of the present invention to provide a 
tile cutting device with an auxiliary base for widening the base of the 
tile cutting device so as to facilitate the cutting of a large tile. 
It is another objective of the present invention to provide a tile cutting 
device with an auxiliary base which does not result in an increase in the 
packaging volume of the tile cutting device. 
In keeping with the principles of the present invention, the foregoing 
objectives of the present invention are attained by a tile cutting device 
consisting of a base, two support frames, two guide rods, a slide seat, a 
cutting tool seat, a cutting tool, a press plate, and a grip rod. The base 
is provided in one of two longitudinal sides thereof with an auxiliary 
base which is detachably fastened therewith such that the upper surface of 
the auxiliary base is flush with a tile placing surface of the base. The 
auxiliary base can be secured to the underside of the base without 
resulting in an increase in the total packaging volume of the tile cutting 
device.

DETAILED DESCRIPTION OF THE INVENTION 
As shown in FIGS. 2 and 3, a tile cutting device 20 embodied in the present 
invention is composed of a rectangular base 21, two support frames 22, two 
guide rods 23, a slide seat 24, a tile cutting tool seat 25, a circular 
cutting tool 26, a press plate 27, and a grip rod 28. The tile cutting 
device 20 is basically similar in construction to the prior art tile 
cutter, except that the base 21 is provided with a raised surface 211 
having a protrusion 212 and a threaded hole 213, and that the base 21 is 
provided with an auxiliary base 30 which is detachably attached to the 
base 21. 
The base 21 is provided at one end thereof with an auxiliary ruler 29 
contiguous to the raised surface 211. The auxiliary base 30 is rectangular 
in shape and is provided at one end of a longitudinal side thereof with a 
shoulder 31 extending therefrom such that the shoulder 31 is perpendicular 
to the upper side of the auxiliary base 30, and that the shoulder 31 is 
provided with an arm 32 extending therefrom. The arm 32 is perpendicular 
to the shoulder 31 and is provided with a first through hole 321 and a 
second through hole 322, which are respectively corresponding in location 
to the protrusion 212 and the threaded hole 213 of the base 21. The 
shoulder 31 has an outer side 311, which is not aligned with a 
longitudinal side 301 of the auxiliary base 30. 
The auxiliary base 30 is detachably fastened with the base 21 such that the 
first through hole 321 of the auxiliary base 30 is engaged with the 
protrusion 212, and that the outer side 311 of the shoulder 31 is engaged 
against a side 214 of the base 21, base 21 and the auxiliary base 30 are 
fastened by a bolt 35 which is engaged with the threaded hole 213 of the 
base 21 via the second through hole 322 of the arm 32 of the auxiliary 
base 30. The auxiliary base 30 has another longitudinal side opposite to 
the longitudinal side 301 and having a rib 33 extending therefrom for 
reinforcing the structural strength of the auxiliary base 30. The 
auxiliary base 30 has an upper surface 302, which is flush with a tile 
placing surface 202 of an elastic pad 201 of the base 21. In other words, 
the auxiliary base 30 gives an added width to the base 21 so as to 
accommodate securely a large tile (not shown in the drawings) to be worked 
on by the tile cutting device 20. 
As illustrated in FIGS. 4 and 5, the auxiliary base 30 can be unfastened 
with the base 21 by loosening the bolt 35. The base 21 is provided in the 
underside thereof with a reinforcing rib 216 extending along the direction 
of the longitudinal axis thereof and having a notch 217. The notch 217 is 
dimensioned to retain the arm 32 of the auxiliary base 30. The base 21 is 
further provided in the underside thereof with a threaded blind hole 218 
which is engaged with the bolt 35 via a third through hole 34 of the 
auxiliary base 30. As a result, the auxiliary base 30 is kept securely in 
the underside of the base 21 when the auxiliary base 30 is not in use.
