Abstract

A portable tile cutter includes a main unit having a base frame and a guard connected to the base frame, a cutter blade pivotally mounted at the guard, a driving unit connected to the guard and operable to rotate the cutter blade, a first handle connected to the driving unit, and a second handle connected to the guard and providing a grip. The component parts of the portable tile cutter are so arranged that moving one or both the driving unit and the second handle can achieve adjustment of the gap between the first handle and the grip of the second handle. Thus, the portable tile cutter can fit different users having different body sizes.

First claim

What is claimed is:

1. A portable tile cutter, comprising:
a main unit comprising a base frame and a guard connected to said base frame;
a cutter blade pivotally mounted at said guard;
a driving unit connected to said guard and operable to rotate said cutter blade;
a first handle connected to said driving unit; and
a second handle connected to said guard, said second handle comprising a grip;
wherein at least one of said driving unit and said second handle is movable to adjust a gap between said first handle and said grip of said second handle,
wherein said driving unit and said second handle are connected to said guard and movable relative to said guard, and
wherein said main unit further comprises a first sliding guide fixedly mounted at said guard and a second sliding guide fixedly mounted at said guard; said driving unit comprises a drive member and a first connection member coupled to said drive member and movable along said first sliding guide; and said second handle further comprises a second connection member movable along said second sliding guide.

2. The portable tile cutter as claimed in claim 1 , wherein said second handle further comprises a pivot connection portion pivotally connected to said base frame.

3. The portable tile cutter as claimed in claim 2 , wherein said second handle further comprises a straight extension rod connected to the grip; and said pivot connection portion of said second handle is connected to one end of said straight extension rod opposite to the said grip of said second handle.

4. The portable tile cutter as claimed in claim 1 , wherein said first sliding guide of said main unit is an arcuate plate comprising an arcuate first sliding slot; said first connection member of said driving unit comprises a first pin rod mounted in said first sliding slot and prohibited from rotation relative to said first sliding slot, a first connection rod fastened to said first pin rod and a first operating grip connected to said first connection rod, and said first connection rod is pivotally connected to said drive member.

5. The portable tile cutter as claimed in claim 4 , wherein said first pin rod of said first connection member of said driving unit comprises a first baffle positioned between said first sliding guide and said guard, a rectangular first engagement block fixedly mounted at said first baffle and a first screw rod fixedly mounted at said first engagement block, said first engagement block is slidably inserted into said first sliding slot and prohibited from rotation relative to said first sliding slot, and said first connection rod is threaded onto said first screw rod.

6. The portable tile cutter as claimed in claim 4 , wherein said first sliding guide of said main unit further comprises an expanded mounting hole disposed in communication with said first sliding slot, and a stopper detachably mounted in between said first sliding slot and said expanded mounting hole.

7. The portable tile cutter as claimed in claim 1 , wherein said second sliding guide of said main unit is an arcuate plate comprising an arcuate second sliding slot; said second connection member of said second handle comprises a second pin rod inserted into said second sliding slot and prohibited from rotation relative to said second sliding slot, a second connection rod fastened to said second pin rod, and a second operating grip connected to said second connection rod.

8. The portable tile cutter as claimed in claim 6 , wherein said second pin rod of said second handle comprises a second baffle positioned between said second sliding guide and said guard, a rectangular second engagement block fixedly mounted at said second baffle, and a second screw rod fixedly mounted at said second engagement block, said second engagement block is slidably inserted into said second sliding slot and prohibited from rotation relative to said second sliding slot, and said second connection rod is threaded onto said second screw rod.
