[0093] A mounting base 2, wherein the mounting base 2 is detachably mounted on the knife sharpening slide 11;

[0094] A knife sharpener 3, wherein the knife sharpener 3 is received in the mounting base 2;

[0095] A knife-sliding plate 5, one end of which is detachably mounted on a side end of the mounting base 2 via a fixing plate 51, and the other end of which is connected to a knife sheath handle 6;

[0096] The knife sheath fastener 4 is sleeved on the knife sheath 1, the mounting base 2, and the knife swinging plate 5, and the knife sheath fastener 4 is clamped on the opening end of the knife sheath handle 6.

[0098] The present invention discloses a portable knife sharpening sleeve, which can sharpen the knife accurately. The knife sleeve handle 6 is provided, so that the knife sleeve is convenient to carry. When the blade needs to be sharpened, the knife sleeve fastener 4 is manually disassembled, so that the knife sleeve 1, the mounting base 2 and the knife swinging plate 5 are separated. At this time, the knife is inserted into the knife sleeve 1, and the position of the knife sleeve 1 close to the blade faces upward. The blade magnetic fixing mechanism 12 located at the position of the knife sleeve 1 close to the blade back absorbs the blade back of the knife, so that the blade part of the knife is located in the middle of two knife sharpening slideways 11, ensuring the accuracy of knife sharpening. The knife sharpener 3 is taken out from the mounting base 2, and the trajectory of the knife sharpening slideway 11 is adapted to the blade part of the knife. The knife handle is arranged in one hand and the knife sharpener 3 is held in the other hand to sharpen the blade of the knife along the knife sharpening slide 11. Due to the arrangement of the knife sharpening slide 11, when the knife sharpener 3 sharpens the blade of the knife along the track of the knife sharpening slide 11, the knife sharpener 3 contacts the blade edge of the knife and slides toward the tip of the knife to complete a sharpening action. The detachable knife-swinging plate 5 meets the demand of not having to carry a knife-swinging plate separately. After the knife blade is used lightly, the knife blade can be sharpened directly on the flat part of the knife-swinging plate 5 to keep the knife blade sharp. The fixed plate 51, the knife-swinging plate 5 and the knife cover handle 6 are arranged in an integrated cowhide style.

When the blade is pulled out of the knife feeding cavity, the friction wheel 72 is driven to rotate in the opposite direction. At this time, the tension on the first rope body 70 disappears. Under the action of the second reset coil spring, the third rotating shaft 83 rotates in the opposite direction, and the second rope coil 79 rewinds the rope body 70 thereon. The first screw 81 connected to the third rotating shaft 83 rotates in the opposite direction, and the transmission screw sleeve 82 sleeved on the first screw 81 moves away from the third rotating shaft 83. The transmission screw sleeve 82 pulls the first slider 84 through the first connecting rod 85 to slide at the bottom end of the fixed square groove 76 toward the rotating shaft fixing seat 77, and the second slider 86 slides on the inner wall of the fixed square groove 76 away from the groove end of the fixed square groove 76. The suction cup 87 is automatically retracted into the fixed square groove 76, and the suction cup 87 releases the suction force on the blade, so that the blade can be easily pulled out of the blade sleeve 1.

[0179] The working principle and beneficial effects of the above technical solution are:

[0180] The tool is inserted into the knife feeding cavity formed at the inner ends of the two blade fixing parts 14. At this time, the blade drives the friction wheel 72 located in the friction wheel fixing groove 71 to rotate around the first rotating shaft 73, thereby driving the fourth rope winding drum coaxially connected to the friction wheel 72 on the first rotating shaft 73 to rotate, and the fourth rope winding drum pulls the second rope body 60, and the second rope body 60 pulls the third rope winding drum 62 located in the third mounting chamber 61 to rotate along the second rotating disk 69 installed in the fourth mounting chamber, and the reset coil spring is stressed. At this time, the third rope winding drum 62 drives the first rotating shaft 63 to rotate, and then drives the transmission sleeve 95 to rotate in the transmission sleeve mounting chamber 94 through the meshing bevel gear 97, and drives the second rotating shaft 68 to rotate through the meshing second transmission gear 67, thereby driving the first transmission gear 65 installed on the second rotating shaft 68 to cooperate with the inner gear ring to rotate along the annular groove 64. At this time, the wiping seat 92 rotates around the first rotating shaft 63 in the wiping seat mounting groove 91, thereby driving The movable wiping block 98 rotates circumferentially to wipe the surface of the blade. As the transmission sleeve 95 rotates, the second screw 96 inserted in the transmission sleeve 95 is driven to rotate. The second screw 96 drives the wiping block 98 to slide in the sliding transverse groove 93 away from the transmission sleeve installation chamber 94, thereby increasing the rotation radius of the wiping block 98. At this time, the extrusion plate connected to the end of the second screw 96 away from the wiping block 98 moves in the oil storage chamber 99 toward the transmission sleeve installation chamber 94, thereby The lubricating oil in the oil storage chamber 99 is squeezed out from the oil outlet hole. The wiping block 98 wipes the lubricating oil on the surface of the blade while cleaning the surface of the blade. The lubricating oil slides to the blade edge of the blade, making it convenient for the sharpener 3 to sharpen the blade. When the blade is pulled out, the friction wheel 72 rotates in the opposite direction, the tension on the second rope body 60 disappears, the return spring connected to the first rotating shaft 63 returns to a natural state, and drives the first rotating shaft 63 to rotate in the opposite direction, and the wiping seat 92 rotates in the opposite direction in the wiping seat mounting groove 91.
