Description

Technical Field

[0001] This utility model relates to the field of handle-free grooving tools, and in particular to a handle-free grooving tool. Background Technology

[0002] Currently, a common way to achieve handle-free functionality is to create a specific groove along the edge of the cabinet door panel. This groove is created using a specialized grooving tool. (See reference...) Figure 1 Traditional handleless grooving knives use an integrated blade with a split hollow structure at the bottom. These knives have a relatively large diameter, and when running at high speed clockwise, they release an upward pulling force, causing the grooved board to shift or deviate, resulting in poor processing accuracy. Furthermore, at high speed, the sawdust is discharged from the bottom upwards, leading to localized knife skipping. In more severe cases, the sawdust cannot be discharged and blocks the groove opening and the cutting edge, causing continuous compression and resulting in an uneven surface on the groove opening. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the aforementioned problems in the prior art, this utility model provides a handle-free grooving knife.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A handle-free grooving knife includes a handle, a blade head, and a cutting edge;

[0008] The cutting head is disposed at one end of the tool holder. The cutting head includes a cutting part and a connecting part. The cutting part is connected to the tool holder through the connecting part. The cutting part is used for grooving cutting.

[0009] The blade is inclinedly disposed on the surface of the handle and above the blade head.

[0010] Preferably, there are two cutting heads, which are fixedly arranged sequentially along the axial direction of the handle, and the two cutting heads are spaced 180 degrees apart in the circumferential direction.

[0011] Preferably, there are two blades, which are fixedly arranged sequentially along the axis of the handle, and the two blades are spaced 180 degrees apart in the circumferential direction.

[0012] Preferably, the surface of the handle is provided with a chip removal groove, and the cutting edge is installed in the chip removal groove.

[0013] Preferably, the cutting part is a rounded-angle cutting edge.

[0014] Preferably, the blade has a 60° bevel.

[0015] (III) Beneficial Effects

[0016] The beneficial effects of this utility model are as follows: By adopting the above technical solution, this application designs the head part and the blade part separately. When grooving, the head part is used first to groove, and then the blade part is used to trim the edge. The split design greatly improves the service life of the handle-free grooving knife. Moreover, when grooving, the sawdust is discharged faster and more efficiently than that of traditional grooving knives. Furthermore, the oblique blade releases the cutting force when it rotates with the handle, so that there is continuous downward pressure when grooving the board, which prevents the grooved board from shifting or deviating and improves the grooving accuracy.

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figure 2 and Figure 3 This utility model provides a handle-free grooving knife, including a handle 1, a blade head 2, and a blade 3;

[0029] The cutting head 2 is disposed at one end of the tool holder 1. The cutting head 2 includes a cutting part 21 and a connecting part 22. The cutting part 21 is connected to the tool holder 1 through the connecting part 22. The cutting part 21 is used for grooving cutting.

[0030] The blade 3 is obliquely disposed on the surface of the handle 1 and above the head 2;

[0031] In use, this application separates the blade head 2 and the blade 3. When grooving, the blade head 2 is used first to groove, and then the blade 3 is used to trim the edge. The split design greatly improves the service life of the handle-free grooving knife. Moreover, when grooving, the sawdust is discharged faster and more efficiently than traditional grooving knives. The oblique blade releases downward cutting force when it rotates with the handle 1, so that there is continuous downward pressure when grooving the board, which prevents the grooved board from shifting or deviating and improves the grooving accuracy.

[0032] In this embodiment, two blades 2 are provided. The two blades 2 are fixedly arranged sequentially along the axial direction of the handle 1, and the two blades 2 are spaced 180 degrees apart in the circumferential direction.

[0033] In this embodiment, there are two blades 3, which are fixedly arranged sequentially along the axial direction of the handle 1, and the two blades 3 are spaced 180 degrees apart in the circumferential direction.

[0034] In this embodiment, the surface of the handle 1 is provided with a chip removal groove 4, and the blade 3 is installed in the chip removal groove 4.

[0035] In this embodiment, the cutting part 21 is a rounded corner cutting edge.

[0036] In this embodiment, the blade 3 is a 60° beveled blade.

[0037] The working principle of this utility model is as follows:

[0038] This application separates the blade head 2 and the blade 3. When grooving, the blade head 2 is used first to groove, and then the blade 3 is used to trim the edge. The split design greatly improves the service life of the handle-free grooving knife. Moreover, when grooving, the sawdust is discharged faster and more efficiently than traditional grooving knives. The oblique blade releases the cutting force when it rotates with the handle 1, so that there is continuous downward pressure when grooving the board, which prevents the grooved board from shifting or deviating and improves the grooving accuracy.
