Specific embodiments

[0025] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand and implement the process of how the present application uses technical means to solve technical problems and achieve technical effects.

[0026] As Figures 1 - 5 shown, the clip for clamping an object provided in this embodiment includes a U-shaped housing 1 and a connecting buckle 2 slidably disposed inside the U-shaped housing 1. One side of the top end of the connecting buckle 2 is fixedly installed with a rack 3. A first half gear 41 is rotatably disposed inside the U-shaped housing 1 and a second half gear 42 fixedly installed at the bottom end of the first half gear 41. The rack 3 meshes with the first half gear 41. Before the U-shaped housing 1 is installed, a steel wire or a thin string is fixed to the connecting buckle 2 first. Pulling the thin string can make the connecting buckle 2 slide downward. At this time, the rack 3 meshes with the first half gear 41, driving the first half gear 4 and the second half gear 42 to rotate;

[0027] The U-shaped housing 1 is rotatably provided with a left clamping member 51 and a right clamping member 52 on both sides corresponding to the first half gear 41 and the second half gear 42. A sector gear 522 is fixedly connected to one side of the right clamping member 52. The lower side of the sector gear 522 meshes with the second half gear 42. A sector half gear 511 is fixedly arranged on one side of the left clamping member 51. The sector half gear 511 meshes with the upper side of the sector gear 522. When the second half gear 42 drives the sector gear 522 to rotate, the wedge-shaped clamping opening 54 of the right clamping member 52 can rotate to the right. At the same time, it drives the sector half gear 511 to rotate. At this time, the wedge-shaped clamping opening 54 at one end of the left clamping member 51 rotates to the left, opening the chuck. After clamping, the steel wire or thin string is released, and the connecting buckle 2 can be reset through an elastic member such as a spring. When the two wedge-shaped clamping openings 54 are reset, the base or edge of the object can be clamped. The elastic member is a prior art and will not be elaborated here.

[0028] Among them, a steel wire or thin string is installed inside the long rod and is bound to the connecting buckle 2 to drive the connecting buckle 2 to slide downward. At this time, the rack 3 slides downward to drive the first half gear 41 to rotate. The second half gear 42 rotates accordingly and drives the sector gear 522 to rotate. The upper end of the sector gear 522 drives the sector half gear 511 to rotate, and thus the left clamping member 51 and the right clamping member 52 can be controlled to expand in opposite directions, thereby realizing the clamping of a distant object through the cooperation of the long rod and the clip.

[0029] Further, as Figures 1 - 5 shown, the U-shaped housing 1 includes a front housing 11 and a rear housing 12. Two pin shafts 13 are fixedly installed inside the rear housing 12. One end of the pin shaft 13 far from the rear housing 12 is fixedly arranged inside the front housing 11. The U-shaped housing 1 is divided into the front housing 11 and the rear housing 12, which is convenient for mass production and also convenient for assembly. Through holes 53 are formed in both the left clamping member 51 and the right clamping member 52. The pin shafts 13 pass through the through holes 53 and are fixedly connected to the front housing 11. Wedge-shaped clamping openings 54 are fixedly connected to the upper ends of the left clamping member 51 and the right clamping member 52. Taking the pin shafts 13 as the rotation centers of the left clamping member 51 and the right clamping member 52 realizes the synchronous rotation of the two wedge-shaped clamping openings 54 and avoids unnecessary displacement or misalignment of them during operation.

[0030] Even further, as Figures 1 - 5As shown in the figure, clamping member rotation cavities 14 are provided at the positions of the front housing 11 and the rear housing 12 corresponding to the left clamping member 51 and the right clamping member 52. The left clamping member 51 and the right clamping member 52 are rotatably arranged inside the clamping member rotation cavities 14 through pin shafts 13. At the upper ends of the left clamping member 51 and the right clamping member 52, wedge-shaped clamping mouths 54 are fixedly connected. The two wedge-shaped clamping mouths 54 are arranged opposite to each other, and the top ends of the wedge-shaped clamping mouths 54 extend to the outside of the front housing 11 and the rear housing 12. On one side of the left clamping member 51 and the right clamping member 52, sliding blocks 55 are fixedly arranged, and the sliding blocks 55 are in contact with the bottom side of the clamping member rotation cavities 14. The clamping member rotation cavities 14 can prevent the left clamping member 51 and the right clamping member 52 from jamming during the rotation process, which helps to improve the structural strength and stability of the entire device.

[0031] Furthermore, as Figures 1 - 5 shown, two sets of symmetrically distributed guide posts 15 are fixedly arranged below the pin shafts 13 on the front housing 11 and the rear housing 12. The guide posts 15 correspond to the edges of the sector half gear 511 and the sector gear 522. The guide posts 15 correspond to the edges of the sector half gear 511 and the sector gear 522, and can provide precise guidance for the rotation of the gears during the movement process. At the positions of the front housing 11 and the rear housing 12 corresponding to the first half gear 41 and the second half gear 42, snap pins 16 are fixedly arranged. The first half gear 41 and the second half gear 42 are rotatably arranged inside the U-shaped housing 1 through the snap pins 16. The snap pins 16 provide rotational support, enabling the first half gear 41 and the second half gear 42 to rotate smoothly inside the U-shaped housing 1, reducing friction and resistance, so that the entire gear transmission system can be compactly installed inside the U-shaped housing 1, saving space, and being beneficial to the miniaturization and lightweight design of the equipment.

[0032] As Figures 1 - 5 shown, the principle of the clip for clamping an object provided in this embodiment is as follows:

[0033] Before the U-shaped housing 1 is installed, first fix a steel wire or a thin string to the connecting buckle 2. Pulling the thin string can make the connecting buckle 2 slide downward. At this time, the rack 3 meshes with the first half gear 41, driving the first half gear 4 and the second half gear 42 to rotate. The second half gear 42 drives the sector gear 522 to rotate, which can make the wedge-shaped clamping mouth 54 of the right clamping member 52 rotate to the right. At the same time, it drives the sector half gear 511 to rotate. At this time, the wedge-shaped clamping mouth 54 at one end of the left clamping member 51 rotates to the left, opening the clip head. After clamping, release the steel wire or the thin string, and the connecting buckle 2 can be reset through an elastic member such as a spring, and the two wedge-shaped clamping mouths 54 can be reset to clamp the base or edge of the object.
