Abstract

The invention discloses a glass knife, which comprises a knife head (14), a knife rod (15), a backup plate, a ruler (12) and a sliding device, wherein the knife head (14) is arranged at one end of the knife rod (15); one end of the ruler (12) is fixedly connected onto the backup plate in the vertical direction; the sliding device is glidingly connected with the ruler (12); and the knife rod (15) is connected with the sliding device and perpendicular to the plane, close to the glass surface, of the ruler (12). After the structure is adopted, the ruler is combined with the knife head and the knife rod, namely the knife head can be driven by the knife rod to be in sliding fit along the ruler, so that a user only needs to carry one glass knife for performing the function of scribing lines on glass; and meanwhile, arbitrary parallel lines can be scribed by enabling a vertical drawing board of the backup plate to be propped against the edge of the glass, the operation is very convenient, and the depth of parallelism is also more accurate.

Description

technical field

[0001] The invention relates to the technical field of cutting tools, in particular to a glass knife. Background technique

[0002] A glass knife refers to a knife used to cut glass. Usually, the part of the glass knife used for cutting is made of diamond or alloy material that is stronger than glass. The glass cutter in the prior art includes a cutter head and a cutter rod, and the cutter head is fixed on the end of the cutter rod. During operation, the user holds the cutter rod with his hand and scratches the cutter head on the glass. But there is following shortcoming in the glass knife of this structure:

[0003] 1) When the glass is cut, the marking line must be smooth and continuous, so that the cut glass section will be smooth and regular. Therefore, the glass knife needs to be equipped with a ruler or other rulers to mark the line when marking. In this way, The user must carry the required ruler or other rulers during operation, and the work cannot ...

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Depend on Figure 1 to Figure 7 As can be seen from the shown structural representation of the glass cutter of the present invention, it comprises a cutter head 14 and a knife bar 15, and said cutter head 14 is arranged at one end of the knife bar 15, and it also includes a backing plate, a ruler 12 and a sliding device, so One end vertical direction of said ruler 12 is fixedly connected on the backing plate, and the slide device is slidably connected with the ruler 12, and the cutter bar 15 is connected with the slide device and is perpendicular to the plane of the ruler 12 close to the glass surface.

[0031] The backing plate is formed by connecting the upper panel 1, the lower panel 16, the vertical panel 3 and the side panel 5, one end of the ruler 12 is fixedly connected to the upper panel 1, and the vertical panel 3 has ...
