Technical Field

[0001] This utility model belongs to the field of carving tool technology, and more specifically, it relates to an adjustable carving knife. Background Technology

[0002] In art and design, carving knives, as a basic hand tool, are widely used for shaping details and depicting textures on the surfaces of various materials, such as wood carving, rubber stamp carving, ceramic decoration, and model finishing.

[0003] Most mainstream carving knives on the market use a fixed handle and blade as one piece or a very limited fixed angle mounting slot, which does not have flexible angle adjustment capabilities. When creators carve curves and slopes with different directions to present a gradient effect, they need to frequently change carving knives of various specifications and angles or adjust their wrists and grips awkwardly. This not only interrupts the creative process and reduces efficiency, but also increases the fatigue and risk of mistakes.

[0004] Based on the structural findings of existing technologies, traditional carving tools are difficult to continuously adjust the angle, and cannot meet the needs of subtle changes in complex carving lines. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an adjustable carving knife, thereby solving the technical problem that traditional carving knives in the prior art cannot achieve continuous angle adjustment.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] Example:

[0029] As attached Figure 1 To be continued Figure 5 As shown:

[0030] This utility model provides an adjustable carving knife, including a handle 1, with an adjustment component installed at one end of the handle 1;

[0031] The adjustment assembly includes a mounting base 2, which is mounted on a handle 1. A ball head 3 is located on one side of the mounting base 2, and an adjustment seat 4 is located on the other side. A pressing head 5 is mounted on one side of the adjustment seat 4, and a fixing seat 6 is mounted around the pressing head 5. Multiple sets of adjustment rails 7 are provided on the fixing seat 6. A return groove 8 is formed on the fixing seat 6, and a return plate 9 is installed within the return groove 8. A spring is installed at the bottom of the return plate 9. A locking groove 10 is formed on the fixing seat 6, and a locking block 11 is installed within the locking groove 10. A ball head seat 12 is installed at the bottom of the return plate 9. Two sets of fixing holes 1 are provided on the fixing seat 6. 3. An adjustment rail 7 is provided in one set of fixing holes 13. The pressing head 5 is locked in multiple sets of adjustment rails 7. One end of the pressing head 5 is connected to the adjustment button 15. The adjustment button 15 is locked in one set of fixing holes 13. The user drives the pressing head 5 to move along the adjustment rail 7 by pressing the adjustment button 15, so that the adjustment seat 4 is disengaged from the adjustment rail 7. After the user releases the adjustment button 15, the spring pushes the return plate 9 to push the adjustment seat 4 laterally through the ball head 3. One end of the pressing head 5 has multiple sets of bevels. The adjustment seat 4 enters the next set of adjustment rails 7 along the bevel of the pressing head 5, completing one angle adjustment.

[0032] One set of fixing holes 13 is connected to the return groove 8. A ball head 3 is inserted through one set of fixing holes 13. The ball head 3 is connected to the ball head seat 12. One end of the return plate 9 is provided with a locking groove. The locking block 11 can be locked in the locking groove. After the angle is adjusted, the locking block 11 is locked in the locking groove by the spherical cooperation between the ball head 3 and the ball head seat 12. At this time, the return plate 9 forms a hard contact with the ball head 3 by constraining the ball head 3 through the ball head seat 12, ensuring that the cutter head assembly does not shift when engraving force is applied, realizing the connection and lateral fixation between the mounting base 2 and the fixing base 6. When the angle adjustment reaches the limit, the user presses the spring of the return plate 9 to compress the spring by pushing the locking block 11 out of the locking groove, and at the same time, the mounting base 2 is returned to center. After releasing the return plate 9, the angle can be adjusted again.

[0033] A cutter head assembly is mounted on one end of the mounting base 6;

[0034] The cutter head assembly includes a locking seat 17, and the locking seat 17 is installed at one end of the fixed seat 6.

[0035] The locking seat 17 has a threaded hole, and an installation head 18 is installed in the threaded hole. The installation head 18 has an installation groove 19, which is formed by two sets of through grooves. A cutter head 20 is installed in the installation groove 19. A fixing sleeve 21 is installed around the installation head 18, and one end of the fixing sleeve 21 is connected to the locking seat 17. The cross-shaped through groove structure of the installation groove 19 can accommodate the mounting shank of different models of cutter heads 20. By rotating the installation head 18, the fixing sleeve 21 tightens the installation groove 19, so that the cutter head 20 does not rotate circumferentially when subjected to transverse cutting force.

[0036] The handle 1 is equipped with a protective cover and two sets of anti-slip blocks 22 around its perimeter. A portable hole is provided at one end of the handle 1. The vertical ridges of the anti-slip blocks 22 form multiple points of contact with the web of the hand, increasing the anti-slip ability when gripping. The portable hole runs through the axis of the handle 1 to meet the needs of hanging and storage.

[0037] The specific usage and function of this embodiment are as follows: When using this device, the adjustment is achieved by pressing the adjustment button 15. Pressing the button drives the pressing head 5 to move along the adjustment rail 7, causing the adjustment seat 4 to disengage from the current guide rail. After releasing the button, the spring pushes the return plate 9, which, through the ball head 3, pushes the adjustment seat 4 laterally, causing it to enter the next set of adjustment rails 7 at an angle along the pressing head 5, completing one angle step. After the angle adjustment is completed, the ball head 3 and the ball head seat 12 engage to lock the locking block 11 into the locking groove. At this time, the return plate 9, through the ball head seat 12, constrains the ball head 3 to form a hard contact, effectively preventing the cutter head assembly from shifting when engraving, and ensuring a stable connection between the mounting seat 2 and the fixed seat 6. When the adjustment limit is reached and reset is required, first push the locking block 11 out of the locking groove, then press the return plate 9 to compress the spring, simultaneously returning the mounting seat 2 to center. After releasing, readjustment is possible. The cutter head 20 is installed in the mounting slot 19, and its periphery is equipped with a mounting head 18 with a fixing sleeve 21. The cross-shaped through-slot structure of the mounting slot 19 is compatible with the mounting shanks of various cutter heads 20. Rotating the fixing sleeve 21 can drive the locking seat 17 to tighten the threaded force, effectively preventing the cutter head 20 from rotating circumferentially when subjected to transverse cutting force. The anti-slip slider 22 on the handle 1 has vertical raised lines, forming multiple contact points with the hand to enhance anti-slip capability; the portable hole through the shaft meets the needs of hanging and storage.
