[0039] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] See also Figure 1-10 As shown, a knife sharpener with adsorption function, comprising:

[0041] A support base 1, on which a knife sharpening mechanism 2 is provided, and the knife sharpening mechanism 2 is used to sharpen the blade;

[0042] The support base 1 is also provided with an assembly hole 1.1 at the bottom, and a side wall opening 1.11 of the assembly hole 1.1;

[0043] The adsorption mechanism 3 comprises: a suction cup seat 3.1, a plug-in portion 3.11 is arranged above the suction cup seat 3.1, and the plug-in portion 3.11 is plugged into the assembly hole 1.1;

[0044] The adsorption mechanism 3 further comprises a rotating frame 3.2, a transmission assembly 3.3, and an adsorption plate 3.4. The rotating frame 3.2 is arranged inside the plug-in portion 3.11. The rotating frame 3.2 is connected to the adsorption plate 3.4 below the suction cup seat 3.1 through the transmission assembly 3.3. The rotating frame 3.2 rotates through the transmission assembly 3.3 to drive the adsorption plate 3.4 to be adsorbed or de-adsorbed.

[0045] The handle 4 has a connection end 4.1 which is inserted into the assembly hole 1.1 from the opening 1.11 and is detachably connected to the rotating frame 3.2. The rotating frame 3.2 is rotated by the handle 4.

[0046] After adopting the above structure, the knife sharpener with adsorption function of the utility model has the following advantages compared with the prior art: an adsorption mechanism 3 is arranged on the support seat 1, and when the knife needs to be sharpened, the adsorption plate 3.4 is adsorbed with the base by rotating the rotating frame 3.2, and the position of the support seat 1 is firmly fixed, and the user can sharpen the knife through the knife sharpening mechanism 2; the support seat 1 with a stable position will not shake during the knife sharpening, thereby improving the knife sharpening effect and reducing the time required for knife sharpening;

[0047] The adsorption mechanism 3 includes a suction cup seat 3.1, which is plugged into the assembly hole 1.1 through the plug-in portion 3.11 to achieve a detachable connection between the suction cup seat 3.1 and the support seat 1;

[0048] An opening 1.11 is provided on the support seat 1 and is connected to the side wall of the assembly hole 1.1. The connecting end 4.1 of the handle 4 can be inserted into the assembly hole 1.1 through the opening 1.11, and the connecting end 4.1 of the handle 4 is also detachably connected to the rotating frame 3.2. After the above improvement, the adsorption mechanism 3 and the support seat 1 are designed as a detachable structure, and the handle 4 is also designed as a detachable structure with the adsorption mechanism 3 and the support seat 1. The multi-component detachable structural design facilitates the disassembly and assembly of the adsorption mechanism 3 and the maintenance of the adsorption mechanism 3.

[0049] The support frame 3.2 is provided with a rotatable rotating frame 3.2 and a vertically movable bracket 3.31, which is connected to the rotating frame 3.2 through the driving surface 3.22 and the transmission part on the rotating frame 3.2. When in use, the rotating frame 3.2 is rotated to make the suction plate 3.4 adsorbed or desorbed from the surface of the substrate. When the suction plate 3.4 is adsorbed to the surface of the substrate, the position of the support seat 1 is firmly fixed. At this time, the blade of the knife can be placed in the groove 2.12, and the side surface of the blade contacts the sharpening rod 2.1. The knife can be sharpened by pulling it back and forth. Since the position of the support seat 1 is stable, there will be no shaking during sharpening, and the blade can be stably contacted with the sharpening rod 2.1, thereby improving the sharpening effect and increasing the safety of the sharpening operation. After the sharpening is completed, the user rotates the rotating frame 3.2 to make the suction plate 3.4 desorbed from the surface of the substrate, which has the characteristics of simple operation and good user experience.

[0050] As an improvement of the utility model, a connecting portion 3.12 extending upward and having an annular structure is provided above the plug-in portion 3.11, and a ring groove 4.11 is provided at the connecting end 4.1 of the handle 4 for the connecting portion 3.12 to be inserted. After the above improvement, the annular connecting portion 3.12 is adapted to the ring groove 4.11, so that the connecting end 4.1 of the handle 4 and the rotating frame 3.2 can be detachably connected, which has the characteristics of simple structure, low cost, and stable and reliable operation.

[0051] As an improvement of the utility model, a block 3.21 is provided on the circumference of the rotating frame 3.2, and a slot 4.12 is vertically provided on the connecting end 4.1 to fit with the block 3.21. After the above improvement, when the plug-in portion 3.11 of the suction cup seat 3.1 is vertically inserted into the assembly hole 1.1, the block 3.21 on the rotating frame 3.2 can enter the slot 4.12. When the block 3.21 is combined with the slot 4.12, the connecting end 4.1 and the rotating frame 3.2 can rotate synchronously, and the structure is simple, reliable, and easy to disassemble and assemble.

[0052] As an improvement of the utility model, the rotating frame 3.2 is provided with a driving surface 3.22, the driving surface 3.22 is coaxially arranged with the rotating frame 3.2, and the driving surface 3.22 is provided with driving sections with heights from high to low;

[0053] The transmission assembly 3.3 includes a bracket 3.31 and a transmission pin 3.32. The bracket 3.31 is inserted into the inner side of the rotating frame 3.2 and can move vertically. A suction cup frame 3.311 is provided at the lower end of the bracket 3.31. The suction cup 3.4 is connected to the suction cup frame 3.311.

[0054] The transmission pin 3.32 is arranged on the bracket 3.31, and the transmission pin 3.32 contacts the driving surface 3.22.

[0055] The suction plate 3.4 is made of soft material. When the rotating frame 3.2 rotates, the driving surface 3.22 is switched to different height positions to contact the driving pin 3.32 to change the height of the driving pin 3.32;

[0056] When the handle 4 is rotated forward and the rotating frame 3.2 is driven to rotate forward, the side of the driving surface 3.22 with a higher height gradually contacts the transmission pin 3.32 to realize the vertical upward movement of the bracket 3.31. At this time, the suction cup frame 3.311 also drives the adsorption plate 3.4 to move upward, and the upper end surface of the adsorption plate 3.4 abuts against the flange at the bottom of the suction cup seat 3.1. The center of the adsorption plate 3.4 deforms upward and shrinks to close the gap with the suction cup frame 3.311. A sealed cavity is formed between the bottom of the adsorption plate 3.4 and the substrate to be adsorbed on the substrate.

[0057] When the handle 4 is rotated in the opposite direction and drives the rotating frame 3.2 to rotate in the opposite direction, the lower side of the driving surface 3.22 gradually contacts the transmission pin 3.32 to realize the vertical downward movement of the bracket 3.31. At this time, the suction cup frame 3.311 also drives the adsorption plate 3.4 to move downward, the center of the adsorption plate 3.4 deforms downward, and the sealed cavity formed between the bottom of the adsorption plate 3.4 and the substrate disappears and is separated from the substrate.

[0058] Positioning grooves 3.221 are respectively provided at the highest and lowest ends of the driving surface 3.22. The transmission pin 3.32 moves into the positioning groove 3.221 and is fixed to the rotating frame 3.2. The bracket 3.31 cannot move upward or downward. Of course, when external force intervenes and the rotating frame 3.2 is rotated by the handle 4, the transmission pin 3.32 can be moved out of the positioning groove 3.221.

[0059] As an improvement of the present invention, the suction cup frame 3.311 is radially extended outward along the bracket 3.31, and a connecting hole 3.41 is provided at the bottom of the suction cup 3.4. The suction cup frame 3.311 is inserted from the bottom opening 1.11 of the connecting hole 3.41 to support the suction cup 3.4, and the bracket 3.31 at the upper end of the suction cup frame 3.311 passes through the top of the suction cup 3.4. In the above improvement, the suction cup 3.4 is connected to the suction cup frame 3.311 in a floating manner. When the center of the suction cup 3.4 is deformed upward and contracts, the connecting hole 3.41 of the suction cup 3.4 is reduced, and the inner wall is sealed with the peripheral wall of the suction cup frame 3.311 to achieve the sealing of the sealed cavity;

[0060] When the center of the adsorption disk 3.4 is deformed downward and unfolded, the connection hole 3.41 of the adsorption disk 3.4 is enlarged, the inner wall is separated from the peripheral wall of the suction cup frame 3.311, and air can quickly enter the sealed cavity to achieve the desorption of the adsorption disk 3.4. The above can achieve the adsorption disk 3.4 firmly adsorbed to the substrate and can be quickly desorbed from the substrate.

[0061] As an improvement of the present invention, a spring 5 is sleeved on the outer side of the bracket 3.31, and the upper end of the spring 5 is stopped against the suction cup seat 3.1, and the lower end is stopped against the adsorption plate 3.4. When the suction cup frame 3.311 links the adsorption plate 3.4 to rise, the spring 5 is pre-tightened, and a downward pre-tightening force is applied to the adsorption plate 3.4, driving the adsorption plate 3.4 to be in closer contact with the suction cup frame 3.311, thereby improving the sealing effect between the inner wall of the connecting hole 3.41 and the suction cup frame 3.311, and the adsorption plate 3.4 is more firmly adsorbed to the substrate;

[0062] In addition, when the adsorption disc 3.4 made of soft material is used for a long time, the adsorption disc 3.4 is easy to harden and has poor flexibility. When adsorption is performed, the adsorption disc 3.4 is not easy to deform, and a gap is easily formed between the adsorption disc 3.4 and the suction cup frame 3.311, resulting in a poor sealing effect. After using the spring 5, the adsorption disc 3.4 is pressed against the suction cup frame 3.311 after pre-tightening the spring 5, so as to obtain a better sealing effect and improve the service life of the device.

[0063] As an improvement of the present invention, the suction cup seat 3.1 is fixed to the support seat 1 by screws 3.13. After the above improvement, the suction cup seat 3.1 is firmly connected to the support seat 1 and is easy to disassemble.

[0064] As an improvement of the utility model, the sharpening mechanism 2 includes two sharpening rods 2.1, which are arranged in a cross structure, the lower ends of the sharpening rods 2.1 are rotatably connected to the support seat 1, and the upper ends of the sharpening rods 2.1 are provided with a connecting shaft 2.11, which is passed through the curved groove 1.2 on the support seat 1 and is floatingly connected to the support seat 1;

[0065] The area between the upper ends of the two sharpening rods 2.1 and the intersection forms a slot 2.12 for the blade to enter. An elastic member is provided between each sharpening rod 2.1 and the support seat 1. The elastic member pulls the upper ends of the two sharpening rods 2.1 closer together. After the above improvement, when sharpening a knife, the blade can be placed in the slot 2.12. If the blade is thick, the upper ends of the two sharpening rods 2.1 can be driven to move relatively far apart, so that the slot 2.12 is expanded to fit the side of the blade and the peripheral surface of the sharpening rod 2.1.

[0066] The function of the spring 5 is to pull the upper ends of the two sharpening rods 2.1 closer together, thereby keeping the peripheral surfaces of the sharpening rods 2.1 in effective contact with the side surfaces of the blade.

[0067] The position of the adsorption plate 3.4 corresponds to the position of the notch 2.12, and a cushion block is also provided on the suction cup seat 3.1 outside the adsorption plate 3.4.

[0068] As an improvement of the present invention, the upper end height of the support seat 1 is higher than the upper end height of the sharpening rod 2.1, and the support seat 1 is also provided with a slot corresponding to the notch 2.12 for the blade to enter. The support seat 1 is provided with a slot that runs through the front and back for the blade to enter the notch 2.12 for sharpening, and the slot effectively restricts the knife from slipping out; in addition, the height of the support seat 1 is set to be higher than the upper end height of the sharpening rod 2.1, and the sharpening rod 2.1 is located between the uppermost end and the lowermost end of the support seat 1. When the device falls, the support seat 1 may first contact the ground, and the sharpening rod 2.1 may contact the ground and cause damage.

[0069] As an improvement of the utility model, the support seat 1 is provided with a scissor sharpening opening 1.3 running through the front and back, and the sharpening mechanism 2 also includes a sharpening portion 1.31 disposed transversely in the scissor sharpening opening 1.3, and the sharpening portion 1.31 divides the scissor sharpening opening 1.3 into upper and lower portions. After the above improvement, if the scissors need to be sharpened, the two blades of the scissors are respectively placed in the upper and lower scissor sharpening openings 1.3, and both blades of the scissors can contact the sharpening portion 1.31, and the scissors are sharpened by the friction between the sharpening portion 1.31 and the blades. The device integrates the function of sharpening scissors, thereby improving the applicability of the device.

[0070] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
