Description

Technical Field

[0001] The utility model belongs to the technical field of tool storage devices, in particular to a tool storage and clamping tool. Background Art

[0002] In many industries, workers often need to use knives for cutting, trimming and other work. However, there are certain safety hazards in the use and storage of clamped knives, because the blade of the knife is very sharp and it is easy to cut the workers. Therefore, a tool storage and clamping tool is designed to effectively protect the safety of workers and prevent the blade of the knife from being exposed.

[0003] In the prior art, knives are usually stored in knife sheaths or knife holders; knife sheaths are usually made of plastic or leather. The knife sheath can protect the blade by inserting the scabbard or handle of the knife. However, the knife holder is a tool for clamping and storing knives to fix the knives in a specific position. The knife holder is usually made of metal or plastic, and can keep the knife fixed by clamping the handle or scabbard of the knife. However, whether it is a knife sheath or a knife holder, there is a problem that the knife is easy to loosen and fall off; the blade on the loosened knife is exposed, which is easy to scratch the staff.

[0004] The patent with the publication number CN111281561B discloses a scalpel storage device, which effectively solves the problem of sealing the blade of the scalpel by fixing and storing the scalpel and sealing the blade of the scalpel. Different scalpels are placed in order, and the positions of each scalpel can be seen at a glance. This structure only prevents the blade from being exposed by covering the blade, and the blade body is not fixed. During the storage of the blade, the blade is easily displaced, thereby exposing the blade. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example

[0030] A tool storage and clamping tool, such as Figures 1 to 3 As shown, it includes a mounting shell 1, a clip 2, a contact plate 8, a rack 14, a gear and a bidirectional screw rod 13;

[0031] The clip 2 is movably connected to both sides of the mounting shell 1, the contact plate 8 is movably connected to the mounting shell 1 and is located at the bottom of the clip 2, the rack 14 is fixed to one side of the contact plate 8, the bidirectional screw rod 13 is rotatably connected to the mounting shell 1, and the clips 2 on both sides are respectively threadedly connected to the bidirectional screw rod 13; wherein, the threads on both sides of the bidirectional screw rod 13 have opposite rotation directions.

[0032] The gears include a first gear 11 and a second gear 12 . The first gear 11 is rotatably connected in the mounting housing 1 . The second gear 12 is fixed to the middle of the bidirectional screw rod 13 . The first gear 11 is meshed with the rack 14 , and the second gear 12 is meshed with the first gear 11 .

[0033] Specifically, the opening of the mounting shell 1 faces upwards, which is used to facilitate the storage of tools. When in use, the tool is inserted from the opening of the mounting shell 1 and inserted between the clips 2. The tool contacts the contact plate 8 at the bottom of the clip 2, and the tool is pressed downward. The tool pushes the contact plate 8 to move downward, and the contact plate 8 drives the rack 14 to move downward. The rack 14 drives the first gear 11 to rotate, the first gear 11 drives the second gear 12 to rotate, and the second gear 12 drives the bidirectional screw 13 to rotate. Since the threads on both sides of the bidirectional screw 13 rotate in opposite directions, the clips 2 on both sides of the bidirectional screw 13 will approach each other or move away from each other. At this time, it should be ensured that the clips 2 on both sides are close to each other. The clips 2 that are close to each other clamp the tool, and the tool will not be able to continue to be inserted, and it is also difficult to pull out. To pull out the tool, it is necessary to reset the contact plate 8 and reset the rack 14 to drive the first gear 11, the second gear 12 and the bidirectional screw 13. If a knife or tweezers is inserted into the mounting shell 1 , the blade of the knife and the end of the tweezers can be clamped and protected by the clamping piece 2 to prevent the dangerous parts from being exposed, thereby improving safety and stability.

[0034] In a preferred embodiment, Figure 1 to Figure 2 As shown, a plurality of slide bars 3 are arranged in the mounting shell 1, and the clip 2 is slidably connected to the slide bars 3. The slide bars 3 are designed to assist the sliding of the clip 2. The clip 2 can be prevented from tilting when sliding.

[0035] In a preferred embodiment, Figures 1 to 3 As shown, one side of the clip 2 is fixedly connected to the connecting plate 9, and the connecting plate 9 is threadedly connected to the bidirectional screw 13, and the clip 2 is threadedly connected to the bidirectional screw 13 through the connecting plate 9. The design of the connecting plate 9 is to ensure that the clip 2 will not block the insertion of the tool when connected to the bidirectional screw 13.

[0036] In a preferred embodiment, Figures 1 to 3 As shown, a clamp block 7 is fixedly connected to the side of the clamping pieces 2 on both sides that are close to each other. The clamp block 7 is used to stably clamp the tool, which is particularly useful for clamping a relatively thin blade. Further optimized, the cross section of the clamp block 7 is a trapezoidal structure. This structure makes the top of the clamp block 7 an inclined surface, which can have a certain guiding effect, ensuring that the tool can be located between the clamping pieces 2 on both sides after being inserted.

[0037] In a preferred embodiment, Figures 1 to 3 As shown, a telescopic rod 17 is connected to the bottom of the contact plate 8, and the other end of the telescopic rod 17 is connected to the bottom of the mounting shell 1; a compression spring 16 is arranged on the outside of the telescopic rod 17, and one end of the compression spring 16 is connected to the contact plate 8, and the other end is connected to the mounting shell 1;

[0038] like Figures 4 to 5As shown, a ratchet mechanism 10 and a limiting mechanism are also provided in the mounting shell 1. The ratchet mechanism 10 includes an outer disc body 20, an inner ratchet 21, a pawl 18 and a limiting spring piece 19. The outer disc body 20 is rotatably connected in the mounting shell 1, the inner ratchet 21 is rotatably connected to the outer disc body 20, the pawl 18 is hinged on the outer disc body 20, one end of the limiting spring piece 19 is connected to the outer disc body 20, and the other end is connected to the pawl 18. The limiting spring piece 19 is used to pull the pawl 18 to clamp the inner ratchet 21 and make the inner ratchet 21 only rotate in one direction relative to the outer disc body 20.

[0039] One end of the first gear 11 is rotatably connected to the mounting shell 1, and the other end is fixed to the inner ratchet 21; the limiting mechanism includes a rotating rod 5 and a limiting member 4, the rotating rod 5 is rotatably connected to the outer side of the mounting shell 1, the outer side of the rotating rod 5 is provided with a thread, the limiting member 4 is threadedly connected to the rotating rod 5, and one side of the limiting member 4 extends into the mounting shell 1 and contacts the outer disk body 20. After the limiting member 4 contacts the outer disk body 20, it can prevent the outer disk body 20 from rotating.

[0040] Specifically, when in use, after the tool is inserted, it contacts the contact plate 8 at the bottom. The contact plate 8 is pressed by the tool, and the contact plate 8 moves downward, and the contact plate 8 drives the telescopic rod 17 to contract. At the same time, the compression spring 16 shortens. The rack 14 on the contact plate 8 drives the first gear 11 to rotate, and the first gear 11 drives the inner ratchet 21 to rotate. At this time, the pawl 18 will not block the rotation of the inner ratchet 21. The first gear 11 then drives the second gear 12 and the two-way screw 13 to rotate and make the clips 2 approach each other. After releasing the tool, the compression spring 16 will try to push the contact plate 8 to reset. The contact plate 8 drives the first gear 11 to try to reset through the rack 14, and the first gear 11 drives the inner ratchet 21 to try to reset, but the inner ratchet 21 will be restricted by the pawl 18 and cannot rotate. In order to reset the first gear 11, it is necessary to enable the inner ratchet 21 to rotate. By rotating the rotating rod 5, the limit piece 4 is moved outward, and the outer disk body 20 can be rotated after it is no longer in contact with the limit piece 4. At this time, the inner ratchet 21 can drive the outer disk body 20 to rotate through the pawl 18, so that the first gear 11 can be reset, and the first gear 11 drives the second gear 12 and the two-way screw rod 13 to reset, so that the clip 2 is opened, which is convenient for taking out the stored tools.

[0041] In a preferred embodiment, a rotating handle 6 is fixedly connected to the end of the rotating rod 5. The rotating handle 6 is used to facilitate the rotation of the rotating rod 5.

[0042] In a preferred embodiment, a plurality of contact protrusions are fixedly connected to the end surface of the outer plate 20 close to the stopper 4. The contact protrusions are used to increase the friction between the outer plate 20 and the stopper 4 to ensure that the outer plate 20 cannot rotate after contacting the stopper 4.
