The whetstone is detachably fixed to the transition beam. This application, by placing the whetstone on the transition beam of a multi-basin structure, provides convenient access to water and facilitates the removal of dirt generated during sharpening. The structure is simple, economical, and practical. Furthermore, the whetstone on the transition beam between the basins is close to the water source, making it convenient to remove dirt generated during sharpening.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 A whetstone is installed on the upper surface of the middle crossbeam of a double-pool basin 3. It includes a replacement part 1 and a connecting plate 2. The replacement part 1 includes a stacked whetstone block 11, a buffer pad 12, and an adhesive layer 13. The replacement part 1 is bonded to the connecting plate 2 by the adhesive layer 13. The length and width of the connecting plate 2 are one to five millimeters larger than the adhesive layer 13, while the length and width of the whetstone block 11 and the buffer pad 12 are the same. In this way, when the whetstone block 11 is worn and needs to be replaced, the user can easily pry the replacement part 1 from the connecting plate 2 by inserting their fingertip into the gap around the adhesive layer 13, and then attach a new replacement part 1 to the connecting plate 2 for subsequent whetstone use.

[0030] Preferably, the adhesive layer 13 is covered with a release paper 14 on the side away from the buffer pad 12, and at least one release sheet 15 is inserted between the adhesive layer 13 and the release paper 14. The release sheet 15 protrudes from the overlapping area of ​​the adhesive layer 13 and the release paper 14. The release paper 14 can cover the adhesive layer 13 to maintain the adhesiveness of the adhesive layer 13 when the replacement part 1 is not in use. The user can easily peel the adhesive layer 13 from the release paper 14 with the help of the release sheet 15 so that the adhesive layer 13 can be fully exposed and pasted to the connecting plate 2.

[0031] Preferably, the upper surface of the middle crossbeam of the double-pool basin 3 has a buffer pad 12 integrally formed therewith, and the sharpening block 11 is directly covered by the buffer pad 12 as a dressing to form a whole, so that the sharpening block 11 is more firmly installed on the middle crossbeam of the double-pool basin 3.

[0032] Preferably, the sharpening block 11 is made of a flexible substrate, which is attached to a wire mesh or thin steel plate. The sharpening block 11 with the flexible substrate is integrally formed and connected with the adhesive layer 13 and bonded to the middle crossbeam of the double pool basin 3. While maintaining the sharpening feel, the buffer pad 12 can be eliminated, thereby reducing costs. It is worth mentioning that the wire mesh or thin steel plate used as the substrate for the sharpening block 11 with the flexible substrate needs to be pre-annealed, and the annealing temperature should be controlled between 500 and 600 degrees Celsius.

[0033] Example 2

[0034] Reference Figure 1-5 A washbasin for mounting a whetstone includes a double-pool basin 3 with two water tanks on the left and right. After the whetstone is installed in a groove 301 on the upper surface of the middle crossbeam of the double-pool basin 3, the user's left and right hands can be placed in the two water tanks of the double-pool basin 3 for convenient sharpening. The water outlet of the faucet 4 installed on the middle crossbeam of the two water tanks of the double-pool basin 3 can be adjusted to be directly above the groove 301, so as to supply water when sharpening. The wastewater after rinsing the whetstone can also be collected by the two water tanks on the left and right sides of the double-pool basin 3, effectively avoiding pollution.

[0035] The groove 301 has a longitudinal cavity 302 on each of its left and right sides. A shaft rod 5 extending forward and backward is provided in the longitudinal cavity 302. The front of the double pool basin 3 has a threaded hole 303. An adjusting screw head 6 is installed in the threaded hole 303. The adjusting screw head 6 is threaded into the threaded hole 303 and extends to the front end of the double pool basin 3 so that it can be adjusted and rotated by the user. When the user rotates the adjusting screw head 6, the adjusting screw head 6 will move horizontally forward and backward. The adjusting screw head 6 keeps its rotational position unchanged in the threaded hole 303 and will only rotate when subjected to external torsional force.

[0036] The rotating shaft 5 can rotate freely axially within the longitudinal cavity 302, but is restricted from moving horizontally back and forth. The front end of the rotating shaft 5 extends out of the longitudinal cavity 302 and is coaxially connected with the adjusting screw head 6. The end of the adjusting screw head 6 facing the rotating shaft 5 has a mating interface 601. The side wall of the mating interface 601 has a limiting groove 602. The end of the rotating shaft 5 is inserted into the mating interface 601. The limiting ear 51 provided on the side wall of the rotating shaft 5 is exactly in the limiting groove 602, and the length of the limiting ear 51 is less than the limiting groove 602, so that the adjusting screw head 6 can drive the rotating shaft 5 to rotate axially while also being able to move smoothly back and forth.

[0037] At least one inclined groove 304 is provided on the left and right side walls of the setting groove 301. A sliding limiting block 31 is provided in the inclined groove 304. The inclined groove 304 connects the setting groove 301 and the longitudinal cavity 302 so that the sliding limiting block 31 can slide from the setting groove 301 into the longitudinal cavity 302. A vertical moving connector 32 is installed at one end of the sliding limiting block 31 facing the longitudinal cavity 302. The vertical moving connector 32 is vertically movable and installed in the vertical sliding groove inside the sliding limiting block 31, thereby driving the sliding limiting block 31 to move horizontally.

[0038] An eccentric piece 52 is fixedly installed on the outer peripheral wall of the shaft rod 5. A linkage arm 53 connected to the rotating shaft of the vertical moving connector 32 is fixedly installed on the side wall of the eccentric piece 52. One of the rotating shafts of the eccentric piece 52 is coaxial with the rotating shaft of the adjusting screw head 6. The linkage arm 53 is installed at a position away from the rotating shaft of the eccentric piece 52. When the adjusting screw head 6 drives the shaft rod 5 to rotate axially, the linkage arm 53 will rotate around the rotating shaft of the adjusting screw head 6 along with the eccentric piece 52, thereby pulling the vertical moving connector 32 to pull the sliding limit block 31 into the inclined upper groove 304. The length of the vertical sliding groove of the sliding limit block 31 and the length and angle of the inclined upper groove 304 are set so that the sliding limit block 31 can be completely moved into the inclined upper groove 304 without leaving the inclined upper groove 304 after the shaft rod 5 rotates.

[0039] The connecting plate 2 has a downward inclined groove 201 on its left and right side walls, which corresponds to the upward inclined groove 304. The shaft rod 5 can rotate to push the sliding limit block 31 from the upward inclined groove 304 into the setting groove 301, and insert it into the downward inclined groove 201 of the connecting plate 2, thereby further locking the position of the connecting plate 2 to ensure the stability of the whetstone during sharpening. The buffer pad 12 between the sharpening block 11 and the adhesive layer 13 solves the problem of the wobble of the sharpening block 11 during sharpening, making the contact between the blade and the surface of the sharpening block 11 better and the sharpening efficiency higher.

[0040] Preferably, the bottom of the setting tank 301 is provided with a guide tank 305 that connects the setting tank 301 with the two water tanks on the left and right sides of the double pool basin 3, so that the sewage accumulated in the setting tank 301 can flow down smoothly and be discharged without affecting the knife sharpening operation.
