[0022] The following is in conjunction with the appendix Figure 1-19 The following is a further description of the proposed solution:

[0023] See appendix Figure 1-16 An automatically retractable knife holder sharpener includes a fixed base 1 and a movable base 2; the fixed base 1 is fixed to a knife holder; the movable base 2 is retractably mounted on the fixed base 1 to switch between an extended position and a retracted position; a sharpening stone assembly is mounted on the movable base 2; the sharpening stone assembly is located outside the fixed base 1 when the movable base 2 is in the extended position; the sharpening stone assembly is located inside the fixed base 1 when the movable base 2 is in the retracted position.

[0024] The fixed base 1 is provided with an inner cavity 10 for accommodating the movable base 2 and an opening 11 for the movable base 2 to enter and exit the inner cavity 10. The opening 11 is located at the front end of the fixed base 1, and the rear end of the movable base 2 is embedded in the inner cavity 10 through the opening 11 and slides with the inner cavity 10 to perform telescopic movement.

[0025] An elastic reset member is sandwiched between the rear end of the movable seat 2 and the inner cavity 10. The elastic reset member is used to keep the movable seat 2 in a pop-out position so that the movable seat 2 can automatically pop out when it switches to the pop-out position, which is convenient for use.

[0026] When the movable seat 2 is in the retracted position, its front end face is flush with the front end face of the fixed seat 1, or slightly protrudes from the fixed seat 1.

[0027] The elastic reset component is a spring 3; a fixed post 12 is provided in the inner cavity 10 of the fixed seat 1, and a sleeve part is provided in the movable seat 2. One end of the spring 3 is sleeved on the fixed post 12, and the other end of the spring 3 is embedded in the sleeve part 24; when the movable seat 2 is in the retracted position, the sleeve part 24 is sleeved on the outside of the fixed post 12, and the spring 3 is compressed in the space between the sleeve part 24 and the fixed post 12, making it difficult to displace.

[0028] The fixed seat 1 is provided with a slide groove 13 extending along its length direction. The outer wall of the movable seat 2 is provided with a limiting member 4. The limiting member 4 falls into the slide groove 13 and slides along the slide groove 13 when the movable seat 2 is extended. The front end of the slide groove 13 is provided with a front baffle 131. When the movable seat 2 is in the extended position, the limiting member 4 abuts against the front baffle 131 to prevent the movable seat 2 from detaching from the fixed seat 1 when it is extended.

[0029] The limiting member 4 is rotatably mounted on the outer wall of the movable seat 2 to switch between a locked state and an unlocked state; specifically, the movable seat 2 is provided with a shaft hole 21, and the limiting member 4 is provided with a shaft portion 43, which is inserted into the shaft hole 21 and rotates with the shaft hole 21.

[0030] The slide 13 includes two side walls extending along the length of the fixed base 1; the limiting member 4 has vertical surfaces 41 on both sides that slide in cooperation with the two side walls; the limiting member 4 is in an unlocked state when the vertical surfaces 41 are parallel to the side walls of the slide 13; the end of the limiting member 4 is provided with a slot 42; the rear end of the slide 13 is provided with a locking part 134 and a trigger part 136; the limiting member 4 is in a locked state when the locking part 134 falls into the slot 42.

[0031] When the movable seat 2 reaches the retracted position, the limiting member 4 is rotated by the trigger part 136, causing the locking part 134 to fall into the slot 42 and switch to the locked state to lock the retracted position. When the movable seat 2 continues to move backward from the retracted position, the locking part 134 disengages from the slot 42 and is switched to the unlocked state by the trigger part 136. At this time, under the action of the elastic reset member, the movable seat 2 can move forward and pop out to switch to the extended position.

[0032] like Figure 6As shown, the initial position of the movable seat 2 is the retracted position, and the limiting member 4 is in the locked state; in use, as... Figure 7-8 As shown, pressing the movable seat 2 causes it to move backward, disengaging the locking part 134 from the slot 42. The trigger part 136 then rotates the limiting member 4 until its vertical surface 41 is parallel to the side wall of the slide groove, thus switching to the unlocked state. Releasing the hand at this point will automatically pop the movable seat 2 to the extended position. Figure 9 As shown. Similarly, when storing, after pressing the movable seat 2, it moves to one end of the limiting member 4 and contacts the trigger part 136, as shown. Figure 8 As shown, the triggered part 136 then deflects the other end of the limiting member 4, causing the locking part 134 to fall into the slot 42, thus locking the retracted position. Figure 6 As shown.

[0033] This technical solution uses the rotating limiting member 4 to cooperate with the locking part 134 and the trigger part 136 to lock and unlock the retracted position of the movable seat 2. The state of the limiting member 4 can be switched by pressing the movable seat 2 to move it back, thereby switching the position of the movable seat 2. The operation is simple and convenient, improving the user experience.

[0034] The slide 13 has two side walls, namely a first side wall 132 and a second side wall 133. The front baffle 131 connects the front ends of the first side wall 132 and the second side wall 133. The rear end of the first side wall 132 is provided with an expansion surface 135 that is inclined outward to gradually increase the width of the rear end of the slide 13. The trigger part 136 is located behind the expansion surface 135. The rear end of the second side wall 133 is provided with a clearance part 137 that increases the width of the rear end of the slide 13. The connection between the second side wall 133 and the clearance part 137 forms an angle, which is a snap-fit ​​part 134. The expansion surface 135 and the clearance part 137 are provided with a limiting member 4 to provide rotation space.

[0035] The distance between the two vertical surfaces 41 of the limiting member 4 is less than the distance between the two ends of the limiting member 4; both ends of the limiting member 4 are provided with the slot 42; the slot 42 is V-shaped; when the limiting member 4 is in the locked state, the locking part 134 falls into the slot 42 at one end of the limiting member 4 and the other end of the limiting member 4 abuts against the expansion surface 135.

[0036] The limiting component 4 of this technical solution has slots 42 at both ends. Rotating it about 90 degrees can achieve a state switch, which is convenient for operation.

[0037] The side of the fixed base 1 is provided with an openable side cover 14, and the slide groove 13 is provided inside the side cover 14; the cavity wall of the inner cavity 10 is provided with an air-avoiding opening 101 communicating with the slide groove 13, and the side cover 14 covers the air-avoiding opening 101; the limiting member 4 extends out of the air-avoiding opening 101 and falls into the slide groove 13.

[0038] In this technical solution, the slide groove 13 is provided on the side cover 14, which can open the side cover 14 to facilitate the installation of the limiting member 4.

[0039] The inner cavity 10 is provided with a guide groove 102, and the outer wall of the movable seat 2 is provided with a guide rail 22. The guide rail 22 falls into the guide groove 102 and slides with the guide groove 102.

[0040] When the movable seat 2 of this technical solution retracts, it can move smoothly through the cooperation of the guide rail 22 and the guide groove 102, as well as the cooperation of the limiting member 4 and the slide groove 13.

[0041] The movable seat 2 is provided with an openable cover 23. The whetstone assembly is installed inside the movable seat, and the cover 23 covers the whetstone assembly. The whetstone assembly includes at least one grinding wheel 5. The grinding wheel 5 is provided with a grinding hole 51 for grinding tools. The cover 23 is provided with a notch 231 for the tool to extend into the grinding hole 51.

[0042] See Figure 17-19 A tool holder includes a tool holder body 6 and the aforementioned automatically retractable tool holder sharpener. The side of the tool holder body 6 is provided with a mounting hole 61, and the fixing seat 1 is fixed in the mounting hole 61.

[0043] This technical solution installs the whetstone assembly on the movable base 2. The movable base 2 and the fixed base 1 are telescopically movable. The whetstone assembly can retract into the fixed base 1 together with the movable base 2. The fixed base 1 is installed in the mounting hole 61 of the knife holder. That is, when the whetstone is not in use, it can be hidden in the knife holder, which is convenient to store and does not take up space.
