[0023] This application discloses a handheld cutter, including a handle 100; a cutting positioning assembly 200 is installed at one end of the handle 100; the cutting positioning assembly 200 includes a top bracket 210, and a side bracket 220 is connected to the bottom end of the top bracket 210 away from the cutter assembly 300, the side bracket 220 being perpendicular to the top bracket 210; the cutter assembly 300 is slidably mounted on the handle 100 along its length extension direction; wherein, a first rolling assembly 211 is provided at the bottom of the top bracket 210; a positioning member 400 that contacts the side wall of the object to be cut is provided at the end of the side bracket 220 facing the cutter assembly 300.

[0024] In this embodiment, the handle 100 is used for gripping; the cutting positioning component 200 is used for cutting and positioning the object to be cut; taking a tile as an example, during use, the first rolling component 211 at the bottom of the top support 210 engages with the top surface of the tile to form a rolling contact, facilitating smooth movement and cutting of the handheld cutter; the side support 220 is provided with a positioning component 400 at one end facing the cutter assembly 300, which contacts the side wall of the object to be cut, to guide the side wall of the object to be cut; at the same time, the side support 220 and the top support 210 can be perpendicular to each other, thereby abutting the mutually perpendicular top and side surfaces of the tile itself, to ensure that the handheld cutter can move stably along a preset route when moving and cutting, reducing the possibility of swaying.

[0025] In an optional or preferred embodiment, the positioning member 400 and the side bracket 220 are detachably connected, thereby facilitating the installation and removal of the positioning member 400.

[0026] In an optional or preferred embodiment, the cutter assembly 300 is used to move and cut the object to be cut, such as a tile. The cutter assembly 300 itself is conventional technology, and its specific structure will not be described in detail.

[0027] In one optional embodiment, the positioning member 400 and the side bracket 220 are connected by a linear sliding connection assembly 410, which includes a sliding groove and a strip slider for sliding insertion. The positioning member 400 has one of the groove and the strip slider; the side bracket 220 has the other of the groove and the strip slider. Through the cooperation of the strip slider and the groove, the positioning member 400 can achieve the cooperation with the side bracket 200 through the insertion action. At the same time, the strip slider can provide a larger contact area with the groove, making the cooperation more stable. It should be understood that the positioning member 400 can also be fixed after the insertion is completed by a bolt structure or a locking structure to prevent it from shifting during use.

[0028] In an optional or preferred embodiment, the linear sliding connection component 410 is configured as at least one of a T-slot sliding connection structure and a dovetail sliding connection structure.

[0029] In an optional or preferred embodiment, the top support 210 and the side support 220 are integrally formed and connected, thereby improving the overall structural stability.

[0030] In one alternative embodiment, the side of the positioning member 400 facing the cutter assembly 300 is a vertical smooth plane. The smooth plane abuts against the side of the object to be cut, which firstly allows for a larger contact area between the object to be cut and the smooth plane, and since the plane itself matches the side shape of the object to be cut, such as a tile, it is less likely to wobble during movement; secondly, the smooth plane allows for less friction between the object to be cut and the smooth plane, making it easier to move and cut with the handheld cutter.

[0031] In one alternative embodiment, the side of the positioning member 400 facing the cutter assembly 300 is a rolling surface; thereby reducing the friction between the object to be cut and the object, facilitating smooth movement of the handheld cutter; and since the positioning member 400 is detachably connected to the side bracket 220, different positioning members can be disassembled and replaced according to the user's actual needs, for example, replacing the flat positioning member with a positioning member with a rolling surface, and vice versa.

[0032] In one alternative embodiment, the positioning member 400 includes a second rolling assembly 420, which includes a plurality of rollers arranged side by side, the outer surfaces of the plurality of rollers forming a rolling surface; the rollers themselves are standard parts, easy to obtain, and easy to assemble and produce efficiently.

[0033] In one alternative embodiment, the positioning member 400 has a vertical plane at one end facing the cutter assembly 300, and an installation groove extending along the length direction of the positioning member 400 is formed on the vertical plane. The height of the installation groove is less than the height of the object to be cut, and a roller assembly is installed in the installation groove. The roller assembly can protrude outside the installation groove and has an elastic movement tendency in the depth direction of the installation groove.

[0034] When in use, the upper end of the side wall of the object to be cut abuts against the vertical plane of the upper side of the mounting groove, the lower end of the side wall of the object to be cut abuts against the vertical plane of the lower side of the mounting groove, and the middle part of the side wall of the object to be cut abuts against the outer side of the roller assembly. This prevents the handheld cutter from wobbling during use because it abuts against the plane, and the contact between the roller assembly and the side wall of the object to be cut ensures smooth movement of the handheld cutter.

[0035] Optionally, the rolling outer surface formed by the roller assembly is flush with the vertical plane. It should be understood that there is no absolute flush, so the roller assembly can extend slightly beyond the mounting groove and have a tendency to move elastically into the mounting groove. The weight of the object to be cut or the limiting of other sides can prevent the object to be cut from being pushed. There are many ways for the roller assembly to have a tendency to move elastically into the mounting groove. For example, a spring can be provided between the roller assembly and the mounting groove, or the rollers on the roller assembly themselves are elastic. Preferably, the outer side of the rollers on the roller assembly has a rubber coating layer, so that it can have elastic movement while also protecting the rollers.

[0036] In an optional or preferred embodiment, the first rolling assembly 211 includes a groove 212 extending along the length of the top support 210, and a plurality of roller groups 213 rotatably disposed in the groove 212 and spaced apart along the extension direction of the groove 212, so as to form a rolling friction surface through the roller groups 213, which facilitates the smooth movement of the object to be cut. Since the surface of the object to be cut, such as a tile, is usually a large surface, there is no need to consider the sway caused by the gap between the rollers.

[0037] In an optional or preferred embodiment, the roller assembly 213 includes a mounting rod 2131 arranged along the width direction of the groove 212, and rollers 2132 rotatably connected to both ends of the mounting rod 2131; this structure allows the roller assembly 213 to form a stable rolling friction surface while ensuring the compactness of the overall structure.

[0038] In an optional or preferred embodiment, the handle 100 is provided with a scale to facilitate dimensional cutting.
