[0002] In daily life, knife sharpeners are important tools for sharpening knives in the kitchen. When sharpening a knife, the knife is usually held between the hand and the sharpener for sharpening, which makes it impossible to fix the knife surface when adjusting the angle. As a result, the blade of the knife after processing and grinding will be deformed due to uneven force, which will cause the blade of the knife to deform during sharpening, greatly reducing the sharpening effect.

[0003] In order to solve the above problems, the Chinese utility model patent with announcement number CN218427283U discloses a new type of knife sharpener, which fixes the position of the clamp by the combination of bolts and nuts, and then fixes the tool through the fixing piece at the top after the clamp fixes the tool, thereby fixing the tool to achieve stability during tool grinding. However, it is still inconvenient to adjust the grinding angle and cutting surface of the tool by the clamp, especially for special-shaped tools, when different clamping angles are required, there are still great limitations, and there are problems such as single clamping angle, inconvenient angle adjustment and insufficiency.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-7 As shown, a tool fastening device for a knife sharpener comprises a clamp 1 for clamping a tool, such as Figure 6 As shown, the middle of the fixture 1 has a mounting position 102 for mounting a tool. After the tool is placed at the mounting position 102, the tool can be fastened by using a screw connected to the fixture 1, so that the tool is connected and fixed to the fixture 1. The fixture 1 is movably mounted on one side of the sharpener mounting seat 3, and the other side of the mounting seat 3 has a locking device that is connected to the fixture 1 and locks the fixture 1 after the fixture 1 is rotated to a specified angle. By operating or debugging the locking device, the overall structure formed by the tool and the fixture 1 can be adjusted in angle, and then locked by using the locking device, so that when grinding the tool, the tool can be adjusted in angle according to demand.

[0027] Specifically, the locking device includes a connecting rod 6 threadedly connected to one end of the clamp 1, one end of the connecting rod 6 has an external thread and is connected to the clamp 1, and the other end is a cylindrical head, the connecting rod 6 passes through the mounting seat 3 and is sleeved with a lock body 4 on the outside, a lock buckle 7 is sleeved inside the lock body 4 and located on the outside of the connecting rod 6, and the lock buckle 7 and the lock body 4 form an internal cavity. The connecting rod 6 is sleeved with a spring 5 on the outside, one end of the spring 5 abuts against the end wall position of the lock body 4 on the side close to the clamp 1, and the other end abuts against the end wall position of the lock buckle 7 on the side away from the clamp 1. Figure 3 As shown, the spring 5 applies opposite elastic forces to the lock catch 7 and the lock body 4, so that the lock catch 7 applies an outward force to the connecting rod 6, and the connecting rod 6 pulls the clamp 1 to be in a locked state.

[0028] Specifically, an adjusting device for adjusting the positions of the clamp 1 and the connecting rod 6 is installed on the side of the clamp 1 .

[0029] Among them, the adjusting device is a locking bolt 2, a nut, a buckle or a knob located at the end of the connecting rod 6. In this example, the adjusting device is a locking bolt 2, which is installed on the side of the clamp 1. After tightening, the end of the locking bolt 2 can abut against the connecting rod 6. This arrangement is used to avoid relative rotation between the connecting rod 6 and the clamp 1. In addition, the relative fixation of the clamp 1 and the connecting rod 6 can be achieved by setting a nut, a knob, etc. at the end of the connecting rod 6. This fixing method belongs to the conventional locking means in the prior art and will not be elaborated here.

[0030] Specifically, a slot 401 is provided at the end of the lock body 4, and a lock tongue 701 is provided at the outer diameter of the end of the lock buckle 7. The lock buckle 7 can rotate relative to the lock body 4, so that the lock tongue 701 on the lock buckle 7 is placed in the slot 401 at the end of the lock body 4. This state is the unlocked state. At this time, the clamp 1 can be rotated to adjust the angle. After the position of the clamp 1 is determined, the lock tongue 701 is moved out of the slot 401, and the lock tongue 701 is contacted with the end of the lock body 4 to lock it.

[0031] Specifically, the outer end of the lock body 4 is evenly distributed with slope surfaces 402 connected to the grooves 401, and the slope surface 402 extends to the middle position of the end between two adjacent grooves 401 and forms a positioning step 403. The lock tongue 701 of the lock buckle 7 can contact the slope surface 402 during the rotation process to achieve a locked state, and the lock tongue 701 can abut against the positioning step 403 to limit the excessive rotation of the lock tongue 701; the purpose of setting the slope surface 402 is to facilitate the lock tongue 701 to contact the end of the lock body 4 after leaving the groove 401, and gradually apply force to the connecting rod 6, so that the connecting rod 6 gradually applies force to the clamp 1 to complete the locking. When the lock tongue 701 contacts the positioning step 403, the maximum force application point is reached, which can avoid the lock tongue 701 from excessive rotation and re-entering the groove 401.

[0032] Specifically, a boss 301 protruding outward is provided on one side of the mounting seat 3 close to the clamp 1, and a slot 101 matching the boss 301 is provided at the end of the clamp 1. The boss 301 can be placed in the slot 101 to limit the rotation of the clamp 1 on the mounting seat 3. This state is the most commonly used state when the tool is grinding, and it has better stability for tool clamping.

[0033] In addition, in this example, a fixed base 9 is provided below the mounting seat 3, and the fixed base 9 can be set as a clamping plate structure for fixing the entire sharpener. A grinding assembly 8 is provided above the mounting seat 3. The grinding assembly 8 mainly includes an oilstone and a structure for fixing the oilstone. The tool can be ground by operating the grinding assembly 8. This part of the structure belongs to the conventional technical means in the prior art, and its structure and principle will not be described in detail here; in addition, in addition to the above-mentioned fixed base 9 and the structure of the grinding assembly 8, the tool fastening device in this example can also be applied to vertical sharpeners, handheld sharpeners and the like.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
