[0009] The central axis protruding from the top surface of the bottom cylinder is set to the central axis of the annular groove ring penetrating into the cylinder cavity; the top cover is provided with a needle hole facing the annular groove.

[0010] Axially, the top cover is provided with a rod hole; a pressure rod placed in the rod hole is linked to a blade arranged in the top cover to cross-cut into the needle hole through a cross-cutting assembly arranged in the middle of the pressure rod, and the top cover is linked to rotate a certain angle based on the central axis through a ratchet assembly arranged at the bottom of the pressure rod;

[0011] The pressure rod sleeve is provided with a second spring, the top end of the second spring presses the pressure cap, and the bottom end of the second spring presses the top cover.

[0012] The cross-cutting assembly comprises a cone column arranged on a ring pressure rod, the side surface of the cone column longitudinally cuts the end of the handle placed in the first slide groove,

[0013] The knife handle is convex, and the front end of the first spring sleeved on the knife handle presses against the inner wall of the first sliding groove; the blade fixed to the front end of the knife handle cross-cuts into the needle hole in the knife groove.

[0014] The ratchet assembly comprises a second spring, an annular upper ratchet and a lower ratchet;

[0015] The upper ratchet is coaxially fixed to the bottom of the pressure rod, and the bottom of the pressure rod is provided with a shaft hole corresponding to the central axis; longitudinally, a second sliding groove is provided on the inner wall of the ring of the upper ratchet, which is matched with the second sliding rail provided on the outer wall of the central axis;

[0022] The beneficial effects of the present invention are as follows:

[0023] A sharp tool box of the present invention uses a needle clamping component to limit the needle head, which is convenient for transverse cutting and quantitatively controls the amount of transverse cutting, avoiding excessive cutting into the hose filling the box cavity. Moreover, the needle clamping component effectively prevents the needle head in the cylinder from falling out of the cylinder, improving safety; through the downward pressure rod, the middle part of the pressure rod drives the blade to perform transverse cutting through the transverse cutting component, and at the same time, the bottom of the pressure rod makes the top cover rotate a certain angle relative to the bottom cylinder through the ratchet component, avoiding the next needle head falling at the same position in the cylinder, preventing the needle heads from piling up in the cylinder, improving the even distribution rate, and improving the utilization rate of the cylinder cavity of the bottom cylinder.

[0024] A sharp tool box of the present invention has a simple structure and is convenient to use. Only the bottom cylinder needs to be replaced, effectively reducing costs, and has strong practicability and wide applicability. Description of the Drawings

DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] A sharp tool box is composed of a top cover 1 and a bottom tube 2.

[0031] Axially, the top surface of the bottom cylinder 2 is provided with a protruding central axis 9, and the outer wall of the central axis 9 is provided with a longitudinal second slide rail. Around the central axis 9, the top surface of the bottom cylinder 2 is provided with an annular groove 4 penetrating into the cylinder cavity, which is a feed groove.

[0032] Axially, the top cover 1 is provided with a transparent rod hole 14. A pressure rod 5 is placed in the rod hole 14, the top of the pressure rod 5 is a pressure cap, the middle part is a cone column, and the bottom is a fixed upper ratchet 7.

[0033] In the longitudinal direction, the top cover 1 is provided with a needle hole 3 facing the annular groove 4. Preferably, the needle hole 3 is conical, open at the top and constricted at the bottom. A "convex" first slide groove 12 is horizontally arranged in the top cover 1, and a "convex" knife handle 10 is horizontally placed in the first slide groove 12. The blade 13 fixed to the front end of the knife handle 10 cross-cuts the needle hole 3 through the first slide groove 12; the cross section of the end of the knife handle 10 is inclined, which fits the side of the cone column in the middle of the pressure rod 5, and is linked by the side of the cone column moving in the longitudinal direction. In the first slide groove 12, the knife handle 10 is sleeved with a first spring 11 for resetting, and the end of the first spring 11 abuts the inner wall of the first slide groove 12. The pressure rod 5, the first slide groove 12, the knife handle 10, and the blade 13 constitute a cross-cutting assembly. At the bottom of the pressure cap, the pressure rod 5 is sleeved with a second spring 6 for resetting, and the bottom end of the second spring 6 presses the top cover 1.

[0034] In order to limit the pressure rod 5 to slide in the longitudinal direction without circumferential rotation, a second longitudinal slide groove is set on the inner wall of the ring of the upper ratchet 7 (the inner wall of the shaft hole), and a second longitudinal slide rail is set on the outer wall of the central axis 9, so that the pressure rod 5 slides up and down along the second slide rail based on the central axis 9.

[0035] The lower ratchet 8 is encircled by the central axis 9 and matches with the upper ratchet 7. Figure 2 As shown (there is also a dislocation slide bar between the lower ratchet 8 and the upper ratchet 7, which is used to facilitate the lower ratchet 8 to enter the next tooth position when the upper ratchet 7 is pressed down again, so as to link the lower ratchet 8 to rotate in one direction, Figure 2The outer wall of the lower ratchet 8 is provided with a third slide groove in the longitudinal direction, which matches with the third slide rail provided on the inner wall of the rod hole 14; so that the rotating lower ratchet 8 is linked to the top cover 1 to rotate based on the central axis 9 through the rod hole 14, that is, the needle hole 3 of the top cover 1 rotates along the annular groove 4 of the bottom tube 2. The second spring 6, the upper ratchet 7, the lower ratchet 8 and the offset slide bar constitute a one-way ratchet assembly.

[0036] The top cover 1 is also provided with a clamping pin assembly consisting of a fourth sliding slot 17 , a third spring 16 , and a limiting rod 15 .

[0037] The fourth slide groove 17 is in an "I" shape, and the "I"-shaped limit rod 15 is placed in the fourth slide groove 17. The inner end of the upper part of the limit rod 15 is supported by the third spring 16 placed in the fourth slide groove 17, and the outer end is pressed by the blade 13 that cuts into the needle hole 3.

[0038] The outer end of the lower part of the limiting rod 15 is placed at the bottom of the needle hole 3 when the upper part is not pressed by the blade 13, so that the needle hole 3 is in a semi-closed state; when the upper part is pressed by the blade 13, it slides in the fourth slide groove 17 with the upper part, so that the needle hole 3 is in an open state.

[0039] When using,

[0040] The needle with the hose is placed into the needle hole 3, and the head of the needle is limited by the lower part of the limiting rod 15, so that the needle is suspended in the needle hole 3, which plays a positioning effect and facilitates quantitative cutting.

[0041] The pressure rod 5 is pressed, and the downward pressure rod 5 pushes the knife handle 10 to move horizontally, so that the blade 13 crosses the hose on the needle. The blade 13 moves horizontally further, pushing the upper part of the limit rod 15, and the limit rod 15 moves horizontally in linkage, so that the lower part of the limit rod 15 moves out of the needle hole 3, the bottom of the needle hole 3 is unobstructed, and the needle falls into the bottom tube 2 through the annular groove 4.

[0042] At the same time, the downwardly moved pressure rod 5 causes the top cover 1 to rotate relative to the bottom cylinder 2 at a certain angle through the ratchet assembly.

[0043] Repeat the above operation, and the needle is inserted into the bottom tube 2 in an offset manner.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
