Description

Technical Field

[0001] This utility model relates to the field of clamping tools, and in particular to a finger clamp. Background Technology

[0002] Tweezers are tools used to pick up lumps of medicine, metal particles, hair, thorns, and other small objects. They typically consist of two thin metal plates connected at one end, with the other end manipulated manually to pick up the object.

[0003] Chinese patent CN202668388U discloses tweezers with rings, comprising two tweezers whose ends are machined together at an acute angle to each other, with their front ends separated. Each tweezer has a ring machined on its outer side. The tweezers allow users to control the opening and closing of the tweezers by inserting two fingers into the rings and opening and closing them. During use, the rings on the tweezers are worn on the fingers, allowing easy control over the opening and closing of the tweezers. This allows the tweezers to be both closed and opened to handle items of different sizes, making it convenient and practical.

[0004] However, the above technical solution has the following shortcomings: Although the tweezers can control the opening of the tweezers through the set ring to pick up items of different sizes, the tweezers are still like traditional tweezers. When picking up some small or fragile items, improper force may cause damage to the items. In addition, the user needs to have certain skills and experience. At the same time, the ring will squeeze the fingers for a long time and feel uncomfortable. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a finger clip that not only reduces the difficulty of clamping operations and improves the comfort of use, but also allows for adjustment of the clamping effect according to the object being clamped, thus expanding the scope of application.

[0007] Preferably, both the index finger placement slot and the thumb placement slot are provided with removable elastic pads inside.

[0008] Preferably, the clamping surface of the clamping mouth is provided with a plurality of protrusions arranged in a linear array.

[0009] Preferably, the connecting assembly includes a central shaft disposed inside the snap-fit ​​block, a slide rod slidably disposed inside the central shaft, a first rectangular block and a second rectangular block disposed on the slide rod, a spring disposed inside the central shaft, and a push block disposed on the central shaft; the end of the spring away from the central shaft is disposed on the slide rod.

[0010] Preferably, a limiting cylinder is coaxially arranged on the central shaft, and the limiting cylinder is located inside the snap-fit ​​block.

[0011] Preferably, the snap-fit ​​block is provided with an oblong hole for the push block to slide along the slide rod axis.

[0012] Preferably, the slide bar is provided with four guide blocks arranged in a circular array, and the interior of the central shaft is provided with a limiting groove for the guide blocks to slide.

[0013] Preferably, the spring sheet has two rectangular stepped grooves.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] 1. This utility model, through its crane beak-like design, not only facilitates the clamping of items and greatly reduces the difficulty of operation, but also improves finger comfort with the addition of an elastic pad. Furthermore, by changing the sharpness of the clamping tip, it can be adapted to clamp different items, avoiding damage to the items or failure to achieve the desired effect, thus expanding the applicability of the finger clamp.

[0016] 2. This utility model allows for quick installation and disassembly of the upper and lower jaws of the crane beak through a connecting component, facilitating the replacement of damaged crane beaks and improving the practicality of the finger clip. Attached Figure Description

[0023] Example 1

[0024] like Figures 1-5 As shown, the finger clip proposed in this embodiment includes an upper jaw 1 and an elastic mechanism; a lower jaw 3 is provided on the side of the upper jaw 1, and an index finger placement groove 2 and a thumb placement groove 4 are respectively provided on the upper jaw 1 and the lower jaw 3. A clamping mouth 6 is provided on both the upper jaw 1 and the lower jaw 3, and the clamping surfaces of the two clamping mouths 6 are arranged opposite each other. A removable elastic pad 5 is provided inside the index finger placement groove 2 and the thumb placement groove 4. A plurality of linearly arrayed protrusions 7 are provided at the end of the clamping surface of the clamping mouth 6.

[0025] The elastic mechanism includes two connecting blocks 9 respectively disposed on the upper jaw 1 and the lower jaw 3 of the crane, a snap-fit ​​block 10 disposed on the connecting blocks 9, a connecting component disposed inside the snap-fit ​​block 10, and a spring piece 8 that can open to both sides.

[0026] In this embodiment, when using this finger clamp to pick up delicate items in daily life and production, first insert the index finger and thumb into the index finger placement groove 2 and thumb placement groove 4 inside the upper and lower jaws 1 and 3, which have a certain degree of elasticity. The fingers fit snugly in the index finger placement groove 2 and thumb placement groove 4, which not only provides a large contact area, but also allows the finger flexion and extension length to follow the length direction of the finger clamp. With the help of the spring piece 8 and connecting block 9, it is easy to control the rotation of the upper and lower jaws 1 and 3 so that the items can be clamped by the clamping mouth 6. Furthermore, the protrusion 7 improves the clamping effect of the clamping mouth 6, greatly reducing the difficulty of operation. The elastic pad 5 improves the comfort of the fingers and avoids discomfort to the finger joints or skin surface during prolonged use. The sharpness of the clamping mouth 6 can also be changed to suit different objects, avoiding damage to the objects or failure to achieve the desired effect, thus expanding the applicability of the finger clamp.

[0027] Example 2

[0028] like Figures 3-5As shown, this embodiment of the finger clip, compared to the first embodiment, includes a connecting component comprising a central shaft 11 disposed inside the snap-fit ​​block 10, a slide rod 13 slidably disposed inside the central shaft 11, a first rectangular block 14 and a second rectangular block 15 disposed on the slide rod 13, a spring 16 disposed inside the central shaft 11, and a push block 19 disposed on the central shaft 11; one end of the spring 16 away from the central shaft 11 is disposed on the slide rod 13; the snap-fit ​​block 10 is provided with an oblong hole for the push block 19 to slide along the axial direction of the slide rod 13; the slide rod 13 is provided with four guide blocks 17 arranged in a ring array; the central shaft 11 is provided with a limiting groove 18 for the guide blocks 17 to slide; and the spring piece 8 is provided with two rectangular stepped grooves. The guide blocks 17 and the limiting groove 18 guide and limit the movement direction of the slide rod 13, preventing the spring 16 from twisting and ensuring the service life of the spring 16.

[0029] A limiting cylinder 12 is coaxially arranged on the central shaft 11. The limiting cylinder 12 is located inside the snap-fit ​​block 10 and is used to limit the axial position of the central shaft 11 inside the snap-fit ​​block 10.

[0030] In this embodiment, the upper jaw 1 and lower jaw 3 of the crane can be installed and disassembled through the set connecting components, which improves the practicality of the finger clip. When disassembling, the slide bar 13 is moved along the central axis 11 by pushing the push block 19. The slide bar 13 compresses the spring 16 and drives the first rectangular block 14 and the second rectangular block 15 to move until the first rectangular block 14 and the second rectangular block 15 on the slide bar 13 are moved out of the stepped groove of the spring piece 8. Then the snap-fit ​​block 10 can be removed from the spring piece 8. The operation is simple and convenient.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
