[0049] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present application.

[0050] Unless otherwise defined, the technical terms or scientific terms used in the present application should be understood as the usual meaning understood by those of ordinary skill in the art to which the present application belongs. The terms "first", "second" and similar words used in the present application do not represent any order, quantity or importance, but are only used to distinguish different components. The terms "include" or "contain" and similar words mean that the elements or objects before the words cover the elements or objects listed after the words and their equivalents, without excluding other elements or objects. The terms "connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "up", "down", "left", "right" and the like are only used to represent relative positional relationships, which may change accordingly when the absolute position of the described object changes.

[0051] In order to keep the following description of the embodiments of the present application clear and simple, the detailed description of known functions and known components is omitted.

[0052] The present embodiment provides a tool clamping assembly for a tool sharpener, the tool sharpener being provided with a sharpener holder 5, the tool clamping assembly being connected with the sharpener holder 5, the tool clamping assembly being used for clamping a tool, and the tool is ground by the movement of the sharpener holder 5.

[0053] AsFigure 1 As shown, the tool clamping assembly mainly includes an arm body 1 and a clamping arm component 2.

[0054] The first end of the arm body 1 is used to connect to the grinding holder 5. The arm body 1 is provided with a top pin 15 and a driving member 14. The driving member 14 is used to drive the top pin 15 to move back and forth along the axial direction of the arm body 1.

[0055] The clamping arm component 2 includes a first clamping arm 21 and a second clamping arm 22, which are mirror-symmetrical.

[0056] The first clamping arm 21 and the second clamping arm 22 are rotatably connected by a rotating shaft 23, which is connected to the second end of the arm body 1. A torque member is provided on the rotating shaft 23, which is used to apply torque to the two clamping arms so that the first end of the first clamping arm 21 and the first end of the second clamping arm 22 jointly clamp the top pin 15. That is, in the natural state, the clamping arm component 2 clamps the top pin 15.

[0057] When the top pin 15 moves, the first clamping arm 21 and the second clamping arm 22 can rotate synchronously so that the second end of the first clamping arm 21 and the second end of the second clamping arm 22 close together to clamp the tool or separate from each other to release the tool.

[0058] like Figure 1 As shown, when the top pin 15 moves toward the rotating shaft 23, the second end of the first clamping arm 21 and the second end of the second clamping arm 22 close together to clamp the tool; when the top pin 15 moves away from the rotating shaft 23, the second end of the first clamping arm 21 and the second end of the second clamping arm 22 separate to release the tool.

[0059] In this embodiment, the tool clamping assembly ensures that the tool clamping point is centered when clamping the tool on both sides. Compared with traditional clamping assemblies, the tool clamping assembly of this embodiment eliminates the need for frequent use of Allen wrenches when disassembling the tool. It uses the movement of the top pin 15 to control the clamping arm to clamp or unload the tool, which greatly shortens the clamping and disassembly time of the tool.

[0060] like Figure 2 As shown, in some embodiments, the top pin 15 can be a trapezoidal block and can slide along the axial direction of the arm body 1 when it is fitted on the arm body 1. The first side wall 151 and the second side wall 152 of the top pin 15 are mirror symmetrical about the plane of symmetry between the first clamping arm 21 and the second clamping arm 22.

[0061] The first side wall surface 151 of the ejector pin 15 is in abutment with the first end of the first clamping arm 21, and the second side wall surface 152 of the ejector pin 15 is in abutment with the first end of the second clamping arm 22. Since the first side wall surface 151 and the second side wall surface 152 of the first side wall surface 151 of the ejector pin 15 are both inclined surfaces, in the case where the ejector pin 15 rotates away from the rotation shaft 23, the first ends of the two clamping arms can slide along the corresponding inclined surfaces respectively, thereby facilitating the rotation of the two clamping arms.

[0062] Preferably, the shapes of the first side wall surface 151 and the second side wall surface 152 of the ejector pin 15 are both arc surfaces, which can facilitate the sliding of the first ends of the two clamping arms along the corresponding inclined surfaces.

[0063] The structure of the ejector pin 15 in the embodiment can ensure that the center line of the tool is automatically centered during clamping, without frequent adjustment of the clamp.

[0064] As shown in FIG. 1, Figure 1 In some embodiments, the first clamping arm 21 and the second clamping arm 22 can be plate body structures respectively, which can increase the contact area between the two clamping arms and the tool, thereby ensuring the stability of clamping the tool.

[0065] As shown in FIG. 1, Figure 2 In some embodiments, the front wall surface 153 and the rear wall surface 154 of the ejector pin 15 can be flat surfaces respectively, the front wall surface 153 can be directly in abutment with the ejector pin 15, and the rear wall surface 154 can be directly connected with the driving member 14.

[0066] As shown in FIG. 1, Figure 1 In some embodiments, the driving member 14 can be a driving nut, which is located on the side of the ejector pin 15 away from the rotation shaft 23 and is in abutment with the rear wall surface 154 of the ejector pin 15. The driving nut 49 is threadedly connected with the arm body 1, the ejector pin 15 can be sleeved on the arm body 1 and is in clearance fit with the arm body 1, and the rotation of the driving nut 49 can drive the ejector pin 15 to move close to the rotation shaft 23, thereby causing the two clamping arms to clamp the tool.

[0067] For example, the clockwise rotation of the driving nut 49 can push the ejector pin 15 to move forward, thereby causing the second ends of the two clamping arms to close to each other to clamp the tool, and when the driving nut 49 is rotated counterclockwise, the ejector pin 15 moves backward under the action of the force between the two inclined side wall surfaces of the ejector pin 15 and the two clamping arms, thereby causing the second ends of the two clamping arms to separate to release the tool.

[0068] The driving nut 49 is rotated to push the ejector pin 15 to move, which can save labor, and can ensure that a girl can easily clamp the tool, thereby expanding the user population. And due to the self-locking action between the driving nut 49 and the arm body 1, the stability of the two clamping arms clamping the tool can be ensured, and the tool will not fall off and hurt the hand.

[0069] Of course, in other embodiments, the driving member 14 can have other structural forms, for example, the driving member 14 can be a telescopic driving member, the driving member 14 is fixed on the arm body 1, and the telescopic end of the driving member 14 is connected with the ejector pin 15, and the telescopic movement of the driving member 14 controls the movement of the ejector pin 15 along the axial direction of the arm body 1.

[0070] As shown in Figure 1 In some embodiments, the arm body 1 can include at least a first arm body 11, a second arm body 13 and a rotating sleeve 12.

[0071] The rotating sleeve 12 is located between the first arm body 11 and the second arm body 13, the first end of the first arm body 11 forms the first end of the entire arm body 1, and is used for connecting with the tool sharpener 5, and the first end of the second arm body 13 forms the second end of the entire arm body 1, and is used for connecting with the ejector pin 15.

[0072] The rotating sleeve 12 is fixedly connected with the second end of one of the two arm bodies 1, and is threadedly connected with the second end of the other arm body 1, and the ejector pin 15 and the driving member 14 are located on the second arm body 13. In this way, when one of the tool surfaces is ground and the other tool surface is to be ground, the tool can be turned over by rotating the arm body 1 or the rotating sleeve 12, so that the angle between the two surfaces of the tool during the grinding process is kept consistent, without disassembling the tool, saving time and labor.

[0073] The rotating sleeve 12 is fixedly connected with the second end of one of the two arm bodies 1, and is threadedly connected with the second end of the other arm body 1, and the ejector pin 15 and the driving member 14 are located on the second arm body 13. In this way, when one of the tool surfaces is ground and the other tool surface is to be ground, the tool can be turned over by rotating the arm body 1 or the rotating sleeve 12, so that the angle between the two surfaces of the tool during the grinding process is kept consistent, without disassembling the tool, saving time and labor.

[0074] 2 can be turned over by rotating the second arm body 13, thereby realizing the turning over of the tool surface.

[0075] Alternatively, the rotating sleeve 12 is threadedly connected with the second end of the first arm body 11, and is fixedly connected with the second end of the second arm body 13, and the turning over of the clamping arm part 2 can be controlled by rotating the rotating sleeve 12, thereby realizing the turning over of the tool surface.

[0076] As shown in Figure 1As shown, in some embodiments, the tool clamping assembly may further include a rotary joint 3, which connects the first end of the arm 1 to the grinding frame 5. The rotary joint 3 is used to swing the arm 1 relative to the grinding frame 5, thereby adjusting the position of the tool relative to the grinding stone.

[0077] The rotating joint 3 may include a first joint 31 and / or a second joint 32. The first joint 31 can be used to control the arm 1 to swing up and down relative to the grinding frame 5, and can be a bearing structure, etc. The second joint 32 can be used to control the arm 1 to swing relative to the grinding frame 5, and can be a hinge structure, etc.

[0078] like Figure 1 As shown, when the rotating joint 3 includes the first joint 31 and the second joint 32, the first joint 31 can be directly connected to the grinding holder 5, and the second joint 32 connects the first joint 31 and the first end of the arm body 1. Through the cooperation of the first joint 31 and the second joint 32, the arm body 1 can realize both the up-and-down swing of the grinding holder 5 and the left-and-right swing of the grinding holder 5. The two joints, the first joint 31 and the second joint 32, together form a four-axis motion of up-and-down and left-and-right, thereby ensuring that the large-angle left-and-right swing is required during the grinding process, and thus ensuring that tools of different lengths can be ground on the grinding stone, realizing the self-adaptive grinding of various knife types.

[0079] like Figure 3 to Figure 7 As shown, this utility model embodiment also provides a knife sharpener, the sharpening holder 5 mainly includes a sharpening base 4, a sharpening holder 5 and a knife clamping assembly as described in any of the above embodiments.

[0080] The sharpening base 4 can be used to fix a sharpening stone (not shown in the figure). The sharpening stone can be detachably connected to the sharpening base 4, so as to facilitate the replacement of the sharpening stone.

[0081] The sharpening holder 5 is mounted on the sharpening base 4, and the sharpening holder 5 can move relative to the sharpening base 4.

[0082] The first end of the arm 1 in the tool clamping assembly is connected to the grinding holder 5 and can move with the grinding holder 5, and grind the tool held by the clamping arm 2 by the grinding stone.

[0083] This sharpener ensures that the angles of both sides of the tool remain consistent during the sharpening process, eliminating the need to change sides and saving time and effort in clamping the tool.

[0084] In some embodiments, a first guide member is provided on the side of the grinding base 4 opposite to the fixed grinding stone.

[0085] The sharpener also includes a sliding seat 6, on which a second guide member is provided. The first and second guide members can cooperate with each other to allow the sliding seat 6 to slide relative to the sharpening base 4.

[0086] The grinding frame 5 is connected with the sliding seat 6 and can slide with the sliding seat 6.

[0087] As shown in Figure 3 and Figure 4 In the embodiment, the first guide is arranged on the lower surface of the grinding stone, and the two guides are matched at the bottom of the grinding stone, so that the mud or iron filings generated during the grinding process can be prevented from falling on the two guides, thereby affecting the sliding of the sliding seat 6.

[0088] In some embodiments, the first guide can be a sliding groove 46 on the bottom of the grinding seat 4, and the grooves of the sliding grooves 46 on the two sides are opposite, and the extension direction of the sliding groove 46 is consistent with the moving direction of the sliding seat 6.

[0089] As shown in Figure 8 The second guide can be a bearing roller 65 arranged on the sliding seat 6, and the two sliding grooves 46 on the grinding seat 4 correspond to the two bearing rollers 65 respectively, and the bearing roller 65 is embedded in the sliding groove 46. Through the cooperation of the bearing roller and the sliding groove 46, the high-precision and low-friction sliding of the sliding seat 6 can be realized, and the sliding seat 6 is silent and has a long service life.

[0090] As shown in Figure 8 In some embodiments, the sliding seat 6 can be provided with an open slot 66 on one side of the two groups of bearing rollers 65 respectively, and the extension direction of the two open slots 66 is consistent with the sliding direction. Further, the sliding seat 6 is provided with an adjusting bolt 63 on both sides along the moving direction thereof, and the two adjusting bolts 63 are embedded in the interior of the sliding seat 6 respectively and respectively extend into the open slot 66, and the end portions of the two adjusting bolts 63 abut against the side walls of the open slot 66. By rotating the two adjusting bolts 63, the width of the open slot 66 can be finely adjusted, and the distance between the two groups of bearing rollers 65 is adjusted, so that the bearing roller 65 can be tightly fitted with the groove wall of the open slot 66, thereby ensuring the stability of the sliding of the bearing roller 65.

[0091] As shown in Figure 8 In some embodiments, the sliding seat 6 can be provided with a first limiting piece 67, and the bottom of the grinding seat 4 is provided with a second limiting piece 45 at both ends in the moving direction of the sliding seat 6. When the sliding seat 6 moves close to the two ends of the grinding seat 4, the first limiting piece 67 can contact the second limiting piece 45, so that the bearing roller 65 on the sliding seat 6 can be prevented from being pulled out of the sliding groove 46 of the grinding seat 4.

[0092] Of course, in other embodiments, the first guide and the second guide can adopt structural forms to achieve high precision and low friction sliding fit. For example, the first guide can be a light pole, and the second guide can be a ball bearing; or the first guide can be a ball bearing, and the second guide can be a light pole.

[0093] As shown in Figure 3 and Figure 5 In some embodiments, the knife sharpener 5 includes a first side support 51 and a second side support 52 arranged at intervals, and a crossbar 53 connecting the first side support 51 and the second side support 52, the crossbar 53 is above the knife grinding seat 4, the knife grinding stone is below the crossbar 53, and the first end of the arm body 1 is connected with the crossbar 53, so that the user can hold the knife with both hands and slide back and forth on the knife grinding stone to achieve knife sharpening. The structure of the knife sharpener 5 is simple and does not hinder the user's hand holding the knife.

[0094] The first side support 51 is located at the first side of the knife grinding seat 4, and the second side support 52 is located at the second side of the knife grinding seat 4. The first side support 51 and the first side support 51 are respectively connected with the knife grinding seat 4. The two side supports can be rotated simultaneously to realize the rotation of the knife sharpener 5 relative to the knife grinding seat 4, so as to adjust the included angle between the cutting edge of the knife and the knife grinding stone, so as to better achieve knife sharpening.

[0095] As shown in Figure 3 and Figure 8 In some embodiments, the sliding seat 6 and the two side supports can be respectively provided with coaxially arranged pin shaft holes, and the side supports and the sliding seat 6 can be rotationally connected by the pin shaft 55 penetrating the pin shaft holes on the sliding seat 6 and the pin shaft holes on the side supports.

[0096] Further, in some embodiments, the first side support 51 and the first side support 51 are respectively provided with a fastening mechanism between the first side support 51 and the first side support 51 and the knife grinding seat 4. The fastening mechanism is used to fix the knife sharpener 5. After the user rotates the two side supports to adjust the included angle between the knife and the knife grinding stone, the knife sharpener 5 and the sliding seat 6 can be fixed together by the fastening mechanism, so as to ensure that the knife sharpener 5 does not rotate on the knife grinding stone when the user is sharpening the knife, and the stability of the grinding angle during movement is maintained.

[0097] As shown in Figure 3 and Figure 8 In some embodiments, the fastening mechanism for fixing the knife sharpener 5 and the sliding seat 6 together mainly includes an arc-shaped guide groove 56, a screw hole 62 and a tightening screw 54.

[0098] Among them, the first side support 51 and the second side support are respectively provided with arc-shaped guide grooves 56 penetrating through the opposite sides thereof. The extension direction of the arc-shaped guide groove 56 is consistent with the rotation direction of the two side supports.

[0099] Screw holes 62 are located on the sliding seat 6 and are opposite to the arc-shaped guide groove 56. Tightening screws 54 are respectively inserted into the arc-shaped guide groove 56 and the screw holes 62. By rotating the tightening screws 54, the two side supports can be tightly pressed against the sliding seat 6, thereby fixing the grinding holder 5.

[0100] Preferably, the tightening screw 54 in this embodiment can be a claw screw. Claw screws can achieve torque locking without the need for external wrenches or other tools. Under the structural components, it is ensured that the grinding holder 51 seconds can adjust the angle and 2 seconds can lock, and there is no shaking during grinding. This achieves simpler, more efficient and more convenient angle adjustment, thereby ensuring the grinding effect of the tool.

[0101] Of course, in some other embodiments, the arc-shaped guide groove 56 can also be provided on the sliding seat 6. Correspondingly, the screw hole 62 is provided on the two side brackets. The grinding seat 4 can also be fixed by tightening the screw 54, which is respectively inserted into the arc-shaped guide groove 56 and the screw hole 62.

Figure 3 and Figure 8 and Figure 8 As shown, the angle positioning mechanism may include positioning grooves on two side supports and positioning buttons 64 on the sliding seat 6. The positioning buttons 64 are located at both ends of the sliding seat 6 in the direction of movement.

[0103] The positioning groove is also arc-shaped, and its extension direction is consistent with the rotation direction of the two side supports. The positioning groove is composed of multiple interconnected spherical grooves 57 arranged in sequence. The positioning button 64 is movably mounted on the sliding seat 6 and can move up and down relative to the sliding seat 6. The positioning button 64 is always embedded in one of the spherical grooves 57 of the positioning groove. When the grinding holder 5 rotates to a certain angle, the positioning button 64 will be embedded in the corresponding spherical groove 57 at that angle, thereby achieving the initial positioning of the grinding holder 5. Then, the grinding holder 5 and the sliding seat 6 are fastened together by the fastening mechanism.

[0104] It should be noted that since the positioning button 64 can slide up and down relative to the sliding seat 6, when the grinding holder 5 or the two side supports rotate, the positioning button 64 will be continuously squeezed, thereby adjusting its position among the multiple spherical grooves 57.

[0105] like Figure 3 to Figure 6 As shown, in some embodiments, the sharpener further includes a first movable plate 41 and a second movable plate 42. The first movable plate 41 is located on the first side of the sharpening base 4, and the second movable plate 42 is located on the second side of the sharpening holder 5. The first and second sides of the sharpening base 4 are opposite to each other.

[0106] The first movable plate 41 and the second movable plate 42 are movably connected with the knife grinding seat 4, and the two movable plates can move relative to the knife grinding seat 4 to approach or separate from each other, so as to fix the knife grinding seat 4 on the sink or dismount the knife grinding seat 4 from the sink.

[0107] Specifically, the above-mentioned includes two cases, wherein the first case can be that the two movable plates can move relative to the knife grinding seat 4 to separate from each other, so as to fix the knife grinding seat 4 on the sink. For example, when the two movable plates separate from each other, they can be respectively correspondingly attached to the tank wall, so that the entire knife grinding seat 4 can be fixed above the sink. In this way, the grinding is carried out above the sink, and the water can wash away the dust generated at the first time. The knife grinding stone abrasive is a natural component and will not pollute the environment. The water flushing grinding can quickly flush away the mud and iron filings, ensure the sharpness of the grinding angle, and obtain better effect of uniform and sharp blade tip serrations. When the knife grinding seat 4 needs to be dismounted from the sink, the two movable plates can be controlled to approach each other, so that the distance between the two movable plates is reduced, and the two movable plates no longer abut against the tank wall, so that the knife grinding seat 4 can be conveniently dismounted from the sink.

[0108] Further, the second case can be that the two movable plates can move relative to the knife grinding seat 4 to approach each other, so as to fix the knife grinding seat 4 on the sink. For example, when the two movable plates approach each other, they can be respectively correspondingly attached to the outer wall of the sink, that is, the entire knife grinding seat 4 is clamped on the sink by the two movable plates, so that the entire knife grinding seat 4 can be fixed above the sink. When the knife grinding seat 4 needs to be dismounted from the sink, the two movable plates can be controlled to separate from each other, so that the distance between the two movable plates is greater than the caliber of the tank opening, and the two movable plates no longer abut against the outer wall of the sink, thereby realizing the separation of the knife grinding seat 4 and the sink.

[0109] The structure of the knife sharpener of the embodiment can adapt to sinks of different sizes, and can be used in different home environments, so that the adaptation range is wider, and more effective, cleaner and neater effect is realized.

[0110] The embodiment adopts a telescopic scheme to adapt to sinks of different sizes, and can be used in different home environments, so that the adaptation range is wider, and more effective, cleaner and neater effect is realized.

[0111] In some embodiments, the first movable plate 41 and the second movable plate 42 are connected with the grinding seat 4 through a light pole 47, the length direction of the light pole 47 is consistent with the moving direction of the movable plate, and the sliding stability of the first movable plate 41 and the second movable plate 42 can be ensured through the light pole 47. The extension and retraction driving mode of the first movable plate 41 and the second movable plate 42 is not limited, and the extension and retraction structure of the extension and retraction driving part 14 or the like can be used.

[0112] As shown in FIG. 1, in some embodiments, the knife sharpener can further include a third movable plate 43 and a fourth movable plate 44. Figure 3 to Figure 6

[0113] The third movable plate 43 and the fourth movable plate 44 are movably connected with the grinding seat 45, and the two movable plates can move relative to the grinding seat 45 to approach each other to fix the grinding stone or approach each other to remove the grinding stone. That is, the third movable plate 43 and the fourth movable plate 44 can realize clamping and releasing of the grinding stone. As shown in FIG. 1, support portions 410 can be respectively arranged on the third movable plate 43 and the fourth movable plate 44, so that the grinding seat 45 is clamped on the top of the sink. Figure 3

[0114] In some embodiments, the shape of the grinding seat 4 can be strip-shaped, and the first movable plate 41 and the second movable plate 42 can be located at two ends of the length direction of the grinding seat 4. The first movable plate 41 and the second movable plate 42 can be slidably connected with the two ends of the length direction of the grinding seat 4.

[0115] Further, in some embodiments, the third movable plate 43 and the fourth movable plate 44 are respectively located between the first movable plate 41 and the second movable plate 42, and the grinding seat 4 is provided with a avoiding slot for placing the third movable plate 43 and the fourth movable plate 44 respectively, a screw rod 48 penetrating the avoiding slot, and a nut 49 threadedly connected with the screw rod 48.

[0116] Among them, the third movable plate 43 and the fourth movable plate 44 can be clamped in the avoiding slot and sleeved on the screw rod 48. The third movable plate 43 is located on the side away from the first movable plate 41 of the nut 49, and the fourth movable plate 44 is located on the side away from the second movable plate 42 of the nut 49. One end of the nut 49 is connected with the first movable plate 41 and the second movable plate 42 respectively, and the first movable plate 41 and the second movable plate 42 can drive the screw rod 49 to move forward and backward when moving. The gap between the third movable plate 43 and the fourth movable plate 44 can be adjusted by rotating the nut 49 to push the third movable plate 43 and the fourth movable plate 44 to approach each other.

[0117] In addition, the specific mechanism of the first movable plate 41, the second movable plate 42, the third movable plate 43 and the fourth movable plate 44 of the embodiment is not limited.
