[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 This utility model discloses a grip 1, a bottom mounting base 5 fixedly mounted on the top of the grip 1, a square mounting box 4 fixedly mounted on the top of the bottom mounting base 5, clamping components symmetrically arranged on the inner side of the square mounting box 4 about the central origin, a drive shaft 10 movably mounted in the middle of the grip 1, one end of the drive shaft 10 passing through the bottom mounting base 5 and extending into the interior of the square mounting box 4, a base bevel gear 6 connected to the end of the drive shaft 10 near the clamping components by a pin key, the base bevel gear 6 meshing with the clamping components, a drive component provided at one end of the grip 1, the drive component being fixedly connected to the other end of the drive shaft 10, and a rubber collar 3 provided on the outer side of the grip 1.

[0022] This device drives the clamping assembly by rotating the base bevel gear 6 through the drive component, thereby opening and closing the clamps 11 in the clamping assembly. This changes the traditional linkage output form, making the action of the clamps 11 consistent and ensuring stable clamping during use.

[0023] Specifically, an observation slot 2 is provided on the outer side of the grip 1, and an arc-shaped glass is provided on the inner side of the observation slot 2.

[0024] In this embodiment, an observation slot 2 is provided to pass through the movement state of the drive shaft 10. Marks can be made on the surface of the drive shaft 10, and the closing angle of the clamps 11 is controlled by observing the number of rotations of the marks.

[0025] Specifically, the size of the rubber collar 3 is adapted to the size of the handle 1, and the surface of the rubber collar 3 is provided with control buttons.

[0026] In this embodiment, a rubber collar 3 is provided to increase the friction between the fingers and the grip, ensuring that the fingers can stably grip the handle 1, thereby ensuring that the pliers 11 can accurately clamp. The rubber collar 3 is fixedly connected to the outer surface of the handle 1.

[0027] Control buttons are provided on the surface of the rubber collar 3 to control the operating status of the motor 13. Preferably, the control buttons can be touch buttons or capacitive buttons. The motor 13 is powered on by touching the control buttons. There are two sets of control buttons: one set controls the clockwise rotation of the motor 13 and the other set controls the counterclockwise rotation. The principle is the same as that of a reversing switch, which achieves rotation in different directions by changing the direction of the current in the motor.

[0028] Specifically, the clamping assembly includes a rotating shaft 8, a clamp base 9, an output bevel gear 7, and clamps 11. One end of the rotating shaft 8 is movably mounted on the inner wall of the square mounting box 4. The inner wall of the square mounting box 4 has a shaft hole that matches the rotating shaft 8. The clamp base 9 is fixedly mounted on the inner end of the rotating shaft 8. The output bevel gear 7 is fixedly mounted on the outer side of the rotating shaft 8. The clamps 11 are fixedly mounted on the surface of the clamp base 9.

[0029] In this embodiment, the outer end of the rotating shaft 8 is movably connected to the shaft hole on the outside of the square mounting box 4. The pliers base 9 is used to install the pliers 11. The drive shaft 10 drives the base bevel gear 6 to rotate, thereby driving the two sets of output bevel gears 7 that mesh with the base bevel gear 6 to...

[0030] The clamps rotate in opposite directions, with clockwise rotation of the base bevel gear 6 expanding the clamps 11 and counterclockwise rotation converging and holding the clamps 11.

[0031] The clamp bases 9, which are set at the inner ends of the two sets of rotating shafts 8, are symmetrically arranged at the origin. The output bevel gear 7 moves relative to the base bevel gear 6, thereby realizing the convergence and expansion of the clamps 11.

[0032] Specifically, the surface of the pliers 11 is provided with several sets of plier teeth 12, and both sets of pliers 11 are made of stainless steel.

[0033] In this embodiment, several sets of clamp teeth 12 are provided on the surface of the clamps 11 to enable the two sets of clamps 11 to cooperate with each other to achieve stable clamping. The clamp teeth 12 provided on the surfaces of the two sets of clamps 11 are staggered. When the clamps 11 are closed, the groove formed by the clamp teeth 12 on the surface of one set of clamps 11 engages with the clamp teeth 12 on the surface of the other set of clamps 11.

[0034] Specifically, the drive assembly includes a power sleeve 14 and a motor 13. The power sleeve 14 is fixedly installed at the bottom of the handle 1, and the motor 13 is fixedly installed inside the power sleeve 14. The output end of the motor 13 is fixedly connected to one end of the drive shaft 10. The control button on the rubber collar 3 is electrically connected to the motor 13 and the power sleeve 14.

[0035] In this embodiment, a drive assembly is set up to drive the drive shaft 10, thereby providing a power source for the device. The motor 13 is electrically connected to the power supply in the power sleeve 14, and the motor 13 is electrically connected to the control button. The control button is connected to the power supply. The control button has a reversing function. By pressing the control button, the motor 13 is driven in different directions, thereby meeting the clamping requirements in actual surgical operations.

[0036] Specifically, the two adjacent square mounting boxes 4 are connected by snap-fit ​​15.

[0037] In this embodiment, a buckle 15 is provided between adjacent square mounting boxes 4 to ensure a more stable connection between the square mounting boxes 4. The square mounting boxes 4 are also provided to provide space for the installation of the rotating shaft 8. At the same time, the square mounting boxes 4 and the bottom mounting base 5 cooperate to form a semi-enclosed area, which can effectively protect the output bevel gear 7, the rotating shaft 8 and the clamp base 9.

[0038] The working principle and usage process of this utility model are as follows: When using, hold the handle 1 and grip the rubber collar 3 with your fingers. Adjust the position of the pliers 11 by hand and place the two sets of pliers 11 around the object to be clamped. Then, press the control button on the surface of the rubber collar 3 to power the motor 13. At this time, the motor 13 rotates counterclockwise, which drives the drive shaft 10 to rotate. The drive shaft 10 drives the base bevel gear 6 to rotate, thereby realizing the relative rotation of the two sets of output bevel gears 7. This drives the rotating shaft 8 and the pliers base 9 to converge inward, realizing the convergence and clamping of the pliers 11. There are two sets of control buttons: one set controls the clockwise rotation of the motor 13, and the other set controls the counterclockwise rotation. Therefore, when it is necessary to expand the pliers 11, it is only necessary to control the motor 13 to rotate clockwise to realize the expansion operation of the pliers 11.
