Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a groove drawing knife. Background Art

[0002] When laying ceramic tiles, exterior wall insulation boards and other operations, it is necessary to use a grooving knife to apply adhesive to the board surface. Existing grooving knives usually fix the handle on the blade, and the handle cannot move. It is not convenient to use in some specific work scenarios, which greatly reduces work efficiency. At the same time, due to the needs of various working environments, workers often need to carry many kinds of knives during work, which is very inconvenient to carry. Utility Model Content

[0003] In view of the defects of the existing grooving knives, the technical problem to be solved by the utility model is to provide a grooving knife with an adjustable and detachable handle, which can effectively improve the working efficiency and is easy to carry.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, the utility model is realized through the following technical measures: a grooving knife comprises a blade and a handle, the blade is provided with a guide rail, the edge of the blade is provided with scraping teeth, the handle can slide back and forth along the guide rail, and the handle is fixed to the guide rail by a fastening screw.

[0005] Furthermore, the guide rail is provided with a groove, the base of the handle is provided with a protrusion, and the protrusion is stuck in the groove.

[0006] Furthermore, the handle is provided with an anti-slip rubber sleeve.

[0007] Furthermore, one long side and one short side of the blade are provided with scraping teeth, and the other long side and short side are smooth.

[0008] Compared with the prior art, the advantages of the utility model are: the grooving knife is provided with a guide rail on the blade, and the handle can be moved back and forth on the guide rail to adjust the position. It can be adjusted to the best output position when in use, and the grooving can be applied more smoothly and effectively; the handle and the blade can be disassembled and assembled at will, and in various working environments, the workers only need to replace blades of different specifications, without the need to carry multiple sets of knives, which is more convenient to carry, transport and store; the handle can be detachable and reversible, which can adapt to the usage habits of left-handed workers; the blade is provided with scraping teeth, which has two functions of uniform plastering and scraping strips, and there is no need to replace tools, thereby increasing work efficiency.

[0013] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0014] In the description of the present utility innovation, it should be understood that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "bottom", "top", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present utility innovation and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility innovation.

[0015] Please refer to Figure 1 , Figure 2 The grooving knife provided in this embodiment includes a blade 1, a guide rail 3, a handle 2, and a fastening screw 5. The handle 2 is provided with an anti-slip rubber sleeve 8, the guide rail 3 is fixed on the blade 1, and a groove 6 is provided on the guide rail 3. A protrusion 7 is provided on the base of the handle 2, and the protrusion 7 is stuck in the groove 6. The handle 2 can slide back and forth on the guide rail 3 and work after being fixed by the fastening screw 5. Uniform scraping teeth 4 are provided on one side of the blade 1.

[0016] The grooving knife provided in this embodiment can be operated by loosening the fastening screw 5, sliding the handle 2 to a suitable position, and tightening the fastening screw 5; after removing one handle 2, only one handle 2 can be used for the operation; after removing two handles 2, the two handles 2 can be reversed and installed into the guide rail 3 for operation; the handle 2 can be connected and used with other different blades 1 with guide rails 3 of the same specifications.

[0017] The handle 2 of the grooving knife provided in this embodiment can be moved back and forth on the guide rail 3 to adjust its position. It can be adjusted to the optimal output position when in use, so that the grooving can be applied more smoothly and effectively; the handle 2 and the blade 1 can be disassembled and assembled at will. In various working environments, workers only need to replace blades 1 of different specifications without carrying multiple sets of cutting tools, which is more convenient to carry, transport and store; the handle 2 is detachable and reversible to adapt to the usage habits of left-handed workers; the blade 1 is provided with scraping teeth 4, which has two functions of uniform plastering and scraping strips. There is no need to replace tools, which increases work efficiency.
