[0007] A circle block is screwed onto the inner wall of the storage chamber, and a spiral protrusion is fixedly connected to the circle block. A plurality of protrusions that mesh with the circle sheet are fixedly connected to the outer wall of the circle block. A worm screw is movably connected to the circle block, and the worm screw of the pressing unit can movably extend out of the column, and the worm screw moves toward the needle body. One end of the worm screw extending out of the column is fixedly connected to the sticking block, and a plurality of through-holes are reserved in the sticking block. The through-holes are connected to the end of the storage chamber farther from the vertical block via the ring block. The ring block is retractable, and the end of the through-hole farther from the column is fixedly connected to a rubber sheet, and the rubber sheet is retractable.

[0008] Furthermore, a rubber ring 1 is fixedly connected to a wall surface of the column which is farther from the linkage block 2, and the vertical block can move through the rubber ring 1.

[0009] Furthermore, a second rubber ring is fixedly connected to the side wall surface of the column, and the worm gear can movably pass through the second rubber ring.

[0010] Furthermore, a four-sided bar is fixedly connected to the inner wall of the storage chamber, and a four-sided placement opening is reserved in the worm screw for the four-sided bar to be movably inserted into.

[0013] The beneficial effects of the present invention are:

[0014] 1. The present invention is provided with linkage block 1. In the stage of cutting off the production of acupuncture needles, when the needle body is not pressed, linkage block 1 has the property of attracting iron, cobalt and nickel through the passage of electric current. When no electric current passes through linkage block 1, circle column 1 and connection block 1 remain in their original state. When the needle body is pressed, when the linkage block 1 has electric current passing through, linkage block 1 having the same sex as linkage block 2 is used to move linkage block 2 toward the support platform, shortening the distance between linkage block 2 and the support platform, so as to press the needle body. Linkage block 2 moves toward the support platform to extend connection block 1 and circle column 1. When the needle body is not pressed, when no electric current passes through linkage block 1, connection block 1 and circle column 1 return to their original state. Connection block 1 moves linkage block 2 toward the end farther from the support platform, expanding the distance between linkage block 2 and the support platform, releasing the pressing on the needle body. Linkage block 1 and linkage block 2 are used to press the needle body. Connection block 1 and circle column 1 are conducive to restoring the original state when the pressing is released.

[0015] 2. The present invention is provided with a column. When the column enters the storage port, the cavity between the end of the block closer to the vertical block and the inner wall of the storage chamber expands, and the cavity between the end of the block farther from the vertical block and the inner wall of the storage chamber shrinks, so that the pressure in the cavity between the end of the block closer to the vertical block and the inner wall of the storage chamber becomes lower, and the pressure in the cavity between the end of the block farther from the vertical block and the inner wall of the storage chamber increases. When the pressure decreases, the water-like substance is transformed from water to gas. The heat absorption of the water-like substance when it is transformed from water to gas is beneficial to the cooling treatment of the column. The column cools the needle body through temperature conduction. When the needle body is pressed, it is beneficial to cool the contact surfaces that are pressed against each other and move relatively.

[0016] 3. According to the present invention, through the installation of the sticker, when the column enters the receiving port, the circle block moves toward the end closer to the circle sheet, and the circle sheet rotates the circle block through the interlocking protrusion 2. The positive rotation of the circle block causes the worm to move toward the end closer to the needle body, and the worm pushes the sticker toward the needle body. The stickers of a pair of columns press the needle body to prevent the needle body from being displaced in the cutting stage and to prevent the needle body from being twisted when being pressed. When the column moves away from the receiving port, the circle block moves toward the end farther from the circle sheet, and the circle sheet rotates the circle block in the opposite direction through the interlocking protrusion 2. The reverse rotation of the circle block causes the worm to move toward the end farther from the needle body, thereby releasing the pressure of the sticker on the needle body, that is, when the needle body moves due to traction, the pressure of the sticker on the needle body is released, so that the needle body can move smoothly with the traction.

Specific implementation method:

[0027] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Reference Figure 1-Figure 7The embodiment of the present invention provides a cutting device for acupuncture needles, comprising a support platform 2 and a plurality of pressing units mounted on the support platform 2, a slicer is mounted on the top of the support platform 2, the pressing unit comprises a linkage block 1 3, a connecting block 1 4 and a linkage block 2 5, the linkage block 1 3 and the linkage block 2 5 have the property of attracting iron, cobalt and nickel, the linkage block 1 3 and the linkage block 2 5 are of the same nature, the end of the linkage block 2 5 closer to the support platform 2 is fixedly connected to a vertical bar 1 6, the vertical bar 1 6 is movably connected to the support platform 2, and the vertical bar 1 6 The end farther from the linkage block 25 protrudes out of the support platform 2, the end of the vertical bar 16 farther from the linkage block 25 is fixedly connected to the connection block 262, and the side wall of the vertical bar 16 is movably connected to the circle column 17. The installation of the vertical bar 16 is conducive to the moving track of the lead-belt linkage block 25 to prevent the linkage block 25 from sticking to the needle body 32 and causing the needle body 32 to be not straight. One end of the circle column 17 is fixedly connected to the connection block 262, and the other end of the circle column 17 is fixedly connected to the support platform 2, and the needle body 32 is located between the linkage block 25 and the support platform 2;

[0029] When the needle body 32 is not pressed, the linkage block 13 has the property of attracting iron, cobalt and nickel through the current. When the linkage block 13 has no current, the circle column 17 and the connecting block 14 remain in their original state. When the needle body 32 is pressed, the linkage block 13 has current passing through it, and the linkage block 25 is moved toward the supporting platform 2 through the linkage block 13 with the same property as the linkage block 25, shortening the distance between the linkage block 25 and the supporting platform 2, so as to press the needle body 32, and the linkage block 25 moves toward the supporting platform 2 so that the connecting block 4 and the circle column 1 7 is stretched, and when the needle body 32 is not pressed, when no current passes through the linkage block 3, the connection block 4 and the circle column 7 return to their original state, and the connection block 4 moves with the linkage block 25 toward the end farther from the support platform 2, thereby increasing the distance between the linkage block 25 and the support platform 2, and releasing the pressing on the needle body 32. The linkage block 3 and the linkage block 25 are used to press the needle body 32, and the connection block 4 and the circle column 7 are conducive to restoring the original state when the pressing is released, thereby reducing the loss of the connection block 4 and the circle column 7;

[0030] The end of the linkage block 25 closer to the support platform 2 is fixedly connected to a pair of columns 8, and the needle body 32 is located between the pair of columns 8. The pair of columns 8, the support platform 2 and the linkage block 25 are conducive to the pulling of the needle body 32, and enhance the pulling balance of the needle body 32. A storage port 212 is reserved on the support platform 2 for the column 8 to be movably inserted. When the linkage block 25 moves toward the support platform 2, the column 8 extends into the storage port 212, and the upper wall surface of the storage port 212 is fixedly connected to the vertical block 9. A storage chamber 82 for movably connecting the blocking block 10 is reserved in the column 8. The vertical block 9 can be movably extended into the storage chamber 82, and the lower wall surface of the vertical block 9 is fixedly connected to the upper wall surface of the blocking block 10. A water-like substance is contained between the end of the blocking block 10 closer to the vertical block 9 and the inner wall surface of the storage chamber 82, and the column 8 enters In the stage of the receiving port 212, the cavity between the end of the blocking block 10 closer to the vertical block 9 and the inner wall of the receiving chamber 82 expands, and the cavity between the end of the blocking block 10 farther from the vertical block 9 and the inner wall of the receiving chamber 82 shrinks, so that the pressure in the cavity between the end of the blocking block 10 closer to the vertical block 9 and the inner wall of the receiving chamber 82 becomes lower, and the pressure in the cavity between the end of the blocking block 10 farther from the vertical block 9 and the inner wall of the receiving chamber 82 increases. When the pressure decreases, the water-like substance is transformed from water to gas. The heat absorbed by the water-like substance when it is transformed from water to gas is beneficial to the cooling treatment of the column 8. The column 8 cools the needle body 32 through temperature conduction. When the needle body 32 is pressed against the needle body 32, it is beneficial to cool the contact surfaces that are pressed against each other and move relatively, which is beneficial to reduce the damage to the outer surface of the needle body 32.

[0031] The wall surface of the blocking block 10 far from the vertical block 9 is fixedly connected to a circle piece 21, and a plurality of protrusions 1 are fixedly connected to the side wall of the circle piece 21. A circle block 22 is screwed onto the inner wall surface of the storage chamber 82, and a spiral protrusion is fixedly connected to the circle block 22. A plurality of protrusions 2 that mesh with the circle piece 21 are fixedly connected to the outer wall surface of the circle block 22. A worm screw 23 is movably connected to the circle block 22, and the worm screw 23 of the pressing unit can movably extend out of the column 8, and the worm screw 23 moves toward the needle body 32. One end of the worm screw 23 that extends out of the column 8 is fixedly connected to the sticking block 24. When the column 8 enters the storage port 212, the circle block 22 moves toward the end closer to the circle piece 21, and the circle piece 21 rotates the circle block 22 via the meshing protrusions 2, and the positive rotation of the circle block 22 causes the worm screw 23 to move closer to the needle body 32. The worm 23 pushes the sticker 24 toward the needle body 32, and the stickers 24 of the pair of pillars 8 press against the needle body 32 to prevent the needle body 32 from being displaced in the cutting stage and to prevent the needle body 32 from being twisted when being pressed. When the pillar 8 is protruding away from the receiving opening 212, the circle block 22 moves toward the end farther from the circle sheet 21, and the circle sheet 21 rotates the circle block 22 in the opposite direction through the interlocking protrusions. The circle block 22 rotates in the opposite direction to move the worm 23 toward the end farther from the needle body 32, thereby releasing the sticker 24 from pressing against the needle body 32, that is, releasing the sticker 24 from pressing against the needle body 32 when the needle body 32 is pulled and moves, so that the needle body 32 can move smoothly with the traction, thereby reducing the unnecessary loss of the needle body 32 in the pulling stage.

[0032] A plurality of through openings 242 are reserved in the sticking block 24, and the through openings 242 are connected to the end of the storage chamber 82 farther from the vertical block 9 through the ring block 25. The ring block 25 is elastic, and the end of the through opening 242 farther from the column 8 is fixedly connected to the rubber sheet 26, and the rubber sheet 26 is elastic. The rubber sheet 26 is closer to the needle body 32. When the column 8 enters the storage opening 212, the chamber pressure between the wall of the blocking block 10 farther from the vertical block 9 and the inner wall of the storage chamber 82 rises, and the air is guided into the through opening 242 through the ring block 25 and pushes the rubber sheet 26, so that the rubber sheet 26 protrudes toward the needle body 32 and contacts and presses with the needle body 32 to prevent the needle body 32 from displacement during the cutting stage.

[0033] A rubber ring 27 is fixedly connected to the wall of the column 8 far from the linkage block 2 5, and the vertical block 9 can move through the rubber ring 27. The installation of the rubber ring 27 is conducive to inhibiting the leakage of water-like substances from the gap between the column 8 and the vertical block 9, so as to prevent the needle body 32 from being stained with water-like substances, which is conducive to improving the cooling efficiency of the needle body 32;

[0034] A rubber ring 28 is fixedly connected to the side wall of the column 8, and the worm gear 23 can move through the rubber ring 28. The installation of the rubber ring 28 is conducive to suppressing the air in the cavity between the end of the blocking block 10 farther from the vertical block 9 and the inner wall of the storage chamber 82 from leaking through the gap between the column 8 and the worm gear 23, so as to prevent the pressure in the cavity between the end of the blocking block 10 farther from the vertical block 9 and the inner wall of the storage chamber 82 from becoming low, which is conducive to the air being guided into the through hole 242 through the ring block 25 and pushing the rubber sheet 26, so that the rubber sheet 26 protrudes toward the needle body 32 and contacts and presses with the needle body 32, so as to prevent the needle body 32 from being displaced during the cutting stage.

[0035] A four-sided bar 29 is fixedly connected to the inner wall of the storage chamber 82, and a four-sided placement opening is reserved in the worm gear 23 for the four-sided bar 29 to move into. The installation of the four-sided bar 29 and the four-sided placement opening is conducive to suppressing the rotation of the worm gear 23, and is conducive to the rotating ring block 22 to move the worm gear 23 to prevent the worm gear 23 from rotating with the rotating ring block 22 when moving.

[0036] The end of the linkage block 3 that is closer to the linkage block 25 is fixedly connected to the circle column 210, and the linkage block 25 is fixedly connected to the vertical bar 231 which can move and extend into the circle column 210. The circle column 210 and the vertical bar 231 are both located on the inner side of the connection block 4. The installation of the circle column 210 and the vertical bar 231 is conducive to suppressing the twisting of the connection block 4 when changing the state, and is conducive to enhancing the smoothness of the movement of the linkage block 25. The linkage block 25 is fixedly connected to a pair of vertical bars 6 that can move and penetrate the supporting platform 2, and a pair of columns 8 are located between the pair of vertical bars 6. The installation of the pair of vertical bars 6 enhances the smoothness of the movement of the linkage block 25.

[0037] The specific implementation method is as follows: in the stage of cutting off the production of acupuncture needles, when the needle body 32 is not pressed, the linkage block 3 has the property of attracting iron, cobalt and nickel through the current. When no current passes through the linkage block 3, the ring column 7 and the connecting block 4 remain in their original state. When the needle body 32 is pressed, the linkage block 3 has the same current as the linkage block 25, so that the linkage block 25 moves toward the support platform 2, shortening the distance between the linkage block 25 and the support platform 2, so as to press the needle body 32, and the linkage block 3 is connected to the support platform 2. The block 25 moves toward the support platform 2 to extend the connection block 14 and the circle column 17. When the needle body 32 is not pressed, and no current passes through the linkage block 3, the connection block 14 and the circle column 17 return to their original state. The connection block 14 moves the linkage block 25 toward the end farther from the support platform 2, expanding the distance between the linkage block 25 and the support platform 2, and releasing the pressure on the needle body 32. The linkage block 13 and the linkage block 25 are used to press the needle body 32. The connection block 14 and the circle column 17 are conducive to restoring the original state when the pressure is released.

[0038] When the column 8 enters the receiving port 212, the cavity between the end of the block 10 closer to the vertical block 9 and the inner wall of the receiving chamber 82 expands, and the cavity between the end of the block 10 farther from the vertical block 9 and the inner wall of the receiving chamber 82 shrinks, so that the pressure in the cavity between the end of the block 10 closer to the vertical block 9 and the inner wall of the receiving chamber 82 becomes lower, and the pressure in the cavity between the end of the block 10 farther from the vertical block 9 and the inner wall of the receiving chamber 82 increases. When the pressure decreases, the water-like substance is transformed from water to gas. The heat absorption of the water-like substance when it is transformed from water to gas is beneficial to the cooling treatment of the column 8. The column 8 cools the needle body 32 through temperature conduction. When the needle body 32 is pressed against the needle body 32, it is beneficial to cool the contact surfaces that are pressed against each other and move relatively.

[0039] When the column 8 enters the receiving opening 212, the ring block 22 moves toward the end closer to the ring sheet 21, and the ring sheet 21 rotates the ring block 22 through the interlocking protrusions. The positive rotation of the ring block 22 causes the worm 23 to move toward the end closer to the needle body 32, and the worm 23 pushes the sticking block 24 toward the needle body 32. The sticking blocks 24 of the column 8 press against the needle body 32 to prevent the needle body 32 from being displaced during the cutting stage and to prevent the needle body 32 from being twisted when being pressed. In the case where the column 8 is protruding away from the receiving opening 212, the circle block 22 moves toward the end farther from the circle sheet 21, and the circle sheet 21 causes the circle block 22 to rotate in the opposite direction via the interlocking protrusions. The circle block 22 rotates in the opposite direction to cause the worm screw 23 to move toward the end farther from the needle body 32, thereby releasing the pressure of the sticker 24 on the needle body 32. That is, when the needle body 32 is pulled and moves, the pressure of the sticker 24 on the needle body 32 is released, so that the needle body 32 can move smoothly with the traction.
