Description

Technical Field

[0001] The invention belongs to the field of tile cutting machinery, and in particular relates to a stroke extension mechanism and a tile pusher with the stroke extension mechanism. Background Art

[0002] As a building material, ceramic tiles play an important role in house decoration. Tile pushers are commonly used tile cutting equipment. At the decoration site, tile pushers can be used to split large tiles into multiple tiles of target size to meet different decoration requirements. Manual tile cutters are widely used because of their low requirements on the cutting site, no need to provide electricity and water, easy use, and high cutting efficiency.

[0003] The mainstream tile pushers on the market are generally fixed-size. Due to the current technological development, the size of tile production is getting larger and larger. In the existing technology, the fixed-size tile pushers limit the flexible cutting of large and small tiles. In actual observation, generally, decorators only carry one tile pusher. When encountering tiles that exceed the size of the tile pusher, they need to use an electric cutter to manually cut, which is time-consuming and laborious, and the cutting is uneven, or carry multiple tile pushers of different sizes, which adds a lot of disadvantages to the decorators. There are also attempts in the industry to develop adjustable tile pusher devices, such as CN201308486U. Although it can adjust the stroke of the pusher and ensure that the guide rail is in close contact with the bracket, the adjustment mechanism of the pusher (i.e., the hollow bracket 3) is too complicated; and the adjustable tile pusher device will cause the guide rail to be too long in order to adapt to different tile sizes, which makes the overall size of the adjustable tile pusher device too large, so that the decorators have difficulty carrying it during transportation. Therefore, how to design a device that can solve the above-mentioned problems is a problem that needs to be solved at present. Summary of the invention
