Obviously, the described embodiments represent only a part of the embodiments of the present invention, and not all the embodiments. The directional terms such as "upper", "lower", "left", "right", "inner", "outer", "front" and "rear" used in the description refer to the directions illustrated in the drawings and serve only for describing the present invention and for simplifying the illustration. They do not indicate that the described device must have a particular orientation or must be constructed and operated in a particular orientation, and therefore should not be taken as a limitation of the present invention. Based on the embodiments of the present invention, all other embodiments that can be derived by those skilled in the art without inventive activity fall within the scope of the present invention.Embodiment 1With reference to Figures 1 to 5, the present invention provides a technical solution: a height-adjustable tile cutting tool comprises a base 1, a guide rail 2 and a support plate 3, characterized in that the base 1 comprises at least two base parts 11 fastened together by connecting elements. The guide rail 2 comprises at least two guide rail parts 21, the number and length of which correspond to those of the base parts 11, wherein the guide rail parts 21 are fastened to one another by connecting elements. The connecting elements consist of a connecting plate 41, fastening screws and fastening nuts 42, wherein the connecting plate 41 is connected by the fastening screws and fastening nuts 42 respectively to two adjacent base parts 11 or two adjacent guide rail parts 21. The number of base parts 11 and guide rail parts 21 is 2 The connecting elements comprise a connecting plate 41, at least two fastening screws and at least two fastening nuts 42.This patent allows the connection elements to combine at least two base parts and guide rail parts into a base and a guide rail of suitable length. Assembly is simple, convenient to handle, and the field of application is wide, particularly suited for cutting large tiles. After use, the connecting elements of the base or the guide rail can be disassembled, thereby reducing the length to that of the base or guide rail parts and facilitating transport.Two or more pedestal parts form the pedestal, two or more guide rail parts form the guide rail. In this embodiment, the number of the pedestal parts and guide rail parts is 2 each, which is not limited in other embodiments of the present invention. The base parts are connected by connecting elements, for example the base parts can be connected front and back by connecting elements, respectively, wherein a connecting plate, four fastening screws and four fastening nuts can be used for fastening, respectively. This is not limited in other embodiments of the present invention. The connecting plate connects two adjacent base parts or guide rail parts, respectively, and is arranged inside the base or guide rail, which facilitates assembly and fastening. By connecting the base parts or guide rail parts by the connecting elements, it can be achieved that the connected base parts or guide rail parts have the same cross section and the same height, thereby ensuring that the cutting process is not impaired.The number and length of the guide rail parts correspond to that of the base parts in order to enable corresponding adaptations. For example, if three base parts are used, three guide rail parts are chosen accordingly, in order that the cutting carriage can better slide on the guide rail and cut the tiles.Embodiment 2With reference to Figures 1 to 5, the present invention provides a technical solution: a height-adjustable tile cutting tool comprises a base 1, a guide rail 2 and a support plate 3, characterized in that the base 1 comprises at least two base parts 11 fastened together by connecting elements. The guide rail 2 comprises at least two guide rail parts 21, the number and length of which correspond to those of the base parts 11, wherein the guide rail parts 21 are fastened to one another by connecting elements. The connecting elements consist of a connecting plate 41, fastening screws and fastening nuts 42, wherein the connecting plate 41 is connected by the fastening screws and fastening nuts 42 respectively to two adjacent base parts 11 or two adjacent guide rail parts 21.It further comprises an adjusting device, wherein the adjusting device comprises a toothed wheel 51 and a rack region 52 cooperating with the toothed wheel 51 and having a rack 521. The gear 51 is rotatably fixed to the base plate 3, the rack portion 52 is fixed to the base plate 3 and connected to the base 1, and the rotation of the gear 51 moves the rack portion 52 and the base 1, and the moving device further includes a rotating rod 53, the gear 51 is fixedly connected to the rotating rod 53, the base plate 3 is provided with rotating holes at both ends, the rotating rod 53 is rotatably fixed to the base plate 3 through the two rotating holes, and the rotating rod 53 is provided with fixing blocks at both ends.
