[0023] This application discloses a handheld cutter, including a C-shaped bracket 100. The C-shaped bracket 100 includes a top plate 110, a bottom plate 120, and a side plate 130 connecting the top plate 110 and the bottom plate 120. A handle 200 is connected to one side of the C-shaped bracket 100. A cutting structure 300 is provided on the handle 200 and is positioned relative to the opening of the C-shaped bracket 100. At least one of the three sides of the top plate 110 facing the bottom plate 120, the bottom plate 120 facing the top plate 110, and the side plate 130 facing the cutting structure 300 has a rolling friction plane. The length of the top plate 110 along the rolling friction plane is less than the length of the bottom plate 120 along the rolling friction plane.

[0024] In this embodiment, the C-shaped bracket 100 allows the object to be cut to fit through the opening of the C-shaped bracket 100. For ease of understanding, a ceramic tile is used as an example. The side of the tile abuts against the inner wall of the side plate 130, and the upper and lower surfaces of the tile abut against the inner walls of the top plate 110 and the bottom plate 120, respectively. This multi-directional positioning of the tile ensures stability when the cutting blade structure 300 moves relative to the tile via the handle 200, preventing swaying. Simultaneously, the top plate 110 faces the side of the bottom plate 120... At least one of the three sides of the base plate 120 facing the top plate 110 and the side plate 130 facing the cutter structure 300 has a rolling friction plane, thereby changing the sliding friction between the tile and the C-shaped bracket 100 into rolling friction, reducing the frictional resistance when the handheld cutter moves relative to the tile; and the length of the top plate 110 along the rolling friction plane is less than the length of the base plate 120 along the rolling friction plane, making it easier for the user to directly observe the state of the object to be cut, such as the fit between the object to be cut and the side plate 130.

[0025] In an optional or preferred embodiment, the two end faces of the top plate 110 extending along the rolling friction plane are both located between the lines connecting the two end faces of the bottom plate 120 extending along the rolling friction plane.

[0026] In this embodiment, such as Figure 3 As shown, since the two end faces of the top plate 110 along the length direction are located inside the corresponding end faces of the bottom plate 120, the user can observe the fit between the object to be cut and the side plate 130 at the front and rear, which helps to determine whether the object to be cut has swayed or tilted.

[0027] In an optional or preferred embodiment, a first rolling structure 400 is provided on the side of the top plate 110 facing the bottom plate 120; the first rolling structure 400 includes multiple rows of first rollers arranged at intervals and rotating, the multiple rows of first rollers together forming a rolling friction plane, and the rolling friction plane formed by the multiple first rollers can more stably position and support the object to be cut.

[0028] In an optional or preferred embodiment, the first roller group includes a plurality of first rollers 410 spaced apart from each other and rotatably arranged, and multiple rows of first roller groups are spaced apart along the length direction of the top plate 110; the plurality of first rollers 410 are spaced apart along the width direction of the top plate 110.

[0029] In this embodiment, multiple rows of first rollers are spaced apart along the length of the top plate 110; multiple first rollers 410 are spaced apart along the width of the top plate 110. Thus, the lateral and longitudinal spacing between each first roller 410 allows the user to visually observe the state of more positions of the object to be cut, which helps to more accurately determine whether the object to be cut is swaying. At the same time, by setting the first rolling structure 400 on the top plate 110 to form a rolling friction plane, the friction between the top plate 110 and the top surface of the tile can be reduced, making it easier for the handheld cutter to move relative to the tile.

[0030] Furthermore, the width of the top plate 110 is shorter than the width of the bottom plate 120.

[0031] In an optional or preferred embodiment, the first rolling structure 400 includes a U-shaped groove 420 formed on the corresponding plate surface, a plurality of first rollers 410 are rotatably connected in the U-shaped groove 420, and at least a portion of the body of the first rollers 410 is exposed in the U-shaped groove 420.

[0032] In this embodiment, the U-shaped groove 420 allows most of the body of the first roller 410 to be hidden inside the groove, making the overall structure of the handheld cutter simple and compact, and also more aesthetically pleasing; part of the body of the first roller 410 is exposed outside the U-shaped groove 420, so that the resulting rolling friction plane is also located outside the U-shaped groove 420, so as to make rolling contact with the object to be cut.

[0033] In an optional or preferred embodiment, the U-shaped groove 420 is configured to penetrate the corresponding plate surface along the rolling direction of the rolling friction plane; a plurality of first rollers 410 are detachably rotatably connected within the U-shaped groove 420.

[0034] In this embodiment, the U-shaped groove 420 is configured to penetrate the corresponding plate surface along the rolling direction of the rolling friction plane, thereby facilitating the installation and removal of the first roller 410; for example, when the flatness of the rolling friction plane is poor due to long-term wear, it can be disassembled and replaced.

[0035] In an optional or preferred embodiment, the first roller 410 is arranged horizontally or at an angle, as long as it can form a rolling friction plane.

[0036] In an optional or preferred embodiment, a second rolling structure 600 is provided on the side of the base plate 120 facing the top plate 110. The second rolling structure 600 includes a plurality of rollers 610 spaced apart and rotatably arranged along the length direction of the base plate 120 to form a rolling friction plane. The axial length of the rollers 610 is greater than or equal to the total axial length of all the first rollers 410 on the same first roller group. Unlike the first rolling structure 400, the second rolling structure 600 has lower requirements for the field of view and is mainly for rolling support. Therefore, a long roller structure design is adopted to achieve a good rolling support effect.

[0037] In an optional or preferred embodiment, the second rolling structure 600 further includes a groove formed on the base plate 120 for rotating the roller 610.

[0038] In an optional or preferred embodiment, a third rolling structure 500 is provided on the side of the side plate 130 facing the cutter structure 300. The third rolling structure 500 includes a mounting groove 510, in which a plurality of rotatably arranged second rollers 520 are installed to form a rolling friction plane; wherein the second rollers 520 are arranged horizontally or at an angle.

[0039] In this embodiment, the second roller 520 is disposed in the mounting groove 510 to conceal the body of the second roller 520; the second roller 520 is disposed horizontally or at an angle to form a rolling friction plane.

[0040] In an optional or preferred embodiment, all the second rollers 520 form a rolling friction plane at one end facing the cutter structure 300 and are exposed outside the mounting groove 510 to facilitate rolling contact with the object to be cut.

[0041] In an optional or preferred embodiment, the outer peripheral surface of the second roller 520 faces the opening of the C-shaped bracket 100.

[0042] In an optional or preferred embodiment, the gap width between the top plate 110 and the bottom plate 120 is adjustable, thereby allowing adjustment to accommodate tiles of different thicknesses and improving its applicability.

[0043] In an optional or preferred embodiment, the first roller 410 and / or the second roller 520 and / or the roller 610 have a certain degree of elasticity, thereby facilitating the placement of the object to be cut into the C-shaped bracket 100 for support and positioning.

[0044] In an optional or preferred embodiment, the side plate 130 has an elongated hole 131 extending along the vertical line connecting the top plate 110 and the bottom plate 120. A fastener 132 passes through the elongated hole 131 to connect the top plate 110 or the bottom plate 120.

[0045] In this embodiment, the top plate 110 or the bottom plate 120 can move up and down. After moving to a predetermined position, the top plate 110 or the bottom plate 120 can be fixed to the side plate 130 by the fastener 132 passing through the elongated hole 131. Optionally, the side plate 130 and the bottom plate 120 can be integrally formed, and the width between the top plate 110 and the bottom plate 120 can be adjusted by raising and lowering the top plate 110. Optionally, the side plate 130 and the bottom plate 120 can be integrally formed, and the width between the top plate 110 and the bottom plate 120 can be adjusted by raising and lowering the bottom plate 120. Optionally, the side plate 130 includes a portion, one portion of which is connected to the bottom plate 120 and the other portion is connected to the top plate 110 for adjustment when connected up and down.

[0046] In an optional or preferred embodiment, the handle 200 is connected to the top plate 110 and extends toward the opening direction of the C-shaped bracket 100; the cutter structure 300 is slidably disposed along the extending direction of the handle 200; and the cutter structure 300 is disposed on the side of the handle 200 facing the bottom plate 120.

[0047] In this embodiment, the cutter structure 300 is located opposite the opening of the C-shaped bracket 100, which facilitates the cutting of tiles, while the handle 200 is connected to the top plate 110, which provides sufficient space for the installation of the cutter structure 300. Optionally, the handle 200 is elongated and has graduations, which facilitates the control of the cutting size. Optionally, the handle 200 is provided with a locking structure that cooperates with the cutter structure 300, so that after the cutter structure 300 moves to any position on the handle 200, the position of the cutter structure 300 can be locked by the locking structure.
