[0025] Please refer to Figure 1-5 A fracture reduction nailing pliers, comprising: a reduction nailing pliers body 1, a connecting shaft 2 is movably connected to the middle position of the reduction nailing pliers body 1, and a locking cap 3 is rotatably connected to the connecting shaft 2;

[0026] Bases 4 are fixedly installed symmetrically on the left and right sides of the resetting nailing forceps body 1; and the lower end surfaces of the bases 4 are movably connected with rotating shafts 6.

[0027] Optionally, a screw rod 7 is movably provided in the middle position of the rotating shaft 6, and a handle 8 is rotatably connected to the upper end surface of the screw rod 7. The rotating shaft 6, the screw rod 7, and the base 4 are provided. The main function of the rotating shaft screw rod base is to support and fix the rotating shaft screw rod. The rotating shaft screw rod is usually used as a part of a transmission mechanism to convert rotational motion into linear motion. The base ensures that the rotating shaft screw rod can operate stably by providing support and fixation functions. It can also provide an adjustable mounting point so that the rotating shaft screw rod can be fine-tuned and aligned during work. The base can also connect the rotating shaft screw rod with other related components (such as motors, sensors, etc.) to realize the overall operation of the system. In short, the function of the rotating shaft screw rod base is to provide support, fixation and connection of the rotating shaft screw rod to ensure its normal operation;

[0028] Optionally, a mounting seat 9 is fixedly installed symmetrically on the left and right sides of the reset nailing forceps body 1, and a mounting groove 10 is provided inside the mounting seat 9. The mounting seat 9 and the mounting groove 10 are provided to facilitate installation, and the mounting seat 9 plays a supporting and stabilizing role;

[0029] Optionally, an elastic torsion spring 11 is inserted into the interior of the mounting groove 10, and the torsion spring 11 is in conflict with the inner wall of the reset nailing pliers body 1. The torsion spring 11 is used to control the torsion of the rotating or turning system. They can provide restoring force within the normal working range to keep the system balanced and stable. When the external force or torsion stops, they will release the stored energy and push the system back to its original state. The torsion spring 11 can also be used as a vibration reduction and shockproof device. By absorbing and dispersing the energy from vibration or impact, they can reduce the impact of vibration transmission to other components or structures. In some mechanical devices, torsion springs can be used to transmit torque or torque. They can transfer torque from the driving component to the driven component, thereby realizing power transmission and rotation. In general, the role of torsion springs is to store and release torsional energy, provide restoring force, control torsion, reduce vibration and transmit torque, etc. They play an important function and role in various mechanical systems and devices.

[0030] Optionally, nail pliers 12 are welded symmetrically on the left and right sides of the inner side of the reset nail pliers body 1, and the nail pliers 12 are provided with clamp grooves 13, and the clamp grooves 13 are in a line. The purpose of setting the nail pliers 12 and the clamp grooves 13 is that the nail pliers 12 is a common hand tool for fixing and driving nails. The clamp groove refers to the lower jaw part of the nail pliers, which has a special design and structure. The clamp groove provides a suitable position and shape to fix the head or tail of the nail. When the nails are placed in the clamp groove, they can be tightly fixed by the clamping force of the pliers to prevent the nails from sliding or moving during use. The design of the clamp groove allows the nails to remain stable during the driving process. They usually have certain sizes and shapes to accommodate nails of different types and sizes. By placing the nails in the appropriate clamp groove, the nail pliers can ensure that the nails do not deviate or tilt during the driving process. The clamp groove plays a role in fixing the nails, keeping the nails stable and protecting the user's fingers in the nail pliers. They are an indispensable part of the nailing process and are essential for the safe and effective use of nail pliers;

[0031] Optionally, hook velvet Velcro columns 14 are inserted inside the clamp grooves 13, and hook velvet Velcro columns 14 are connected to hook velvet Velcro 15 on their upper end surfaces. The hook velvet Velcro columns 14 and hook velvet Velcro 15 are provided to function as follows: hook velvet Velcro columns are common fixing devices and are commonly used in various occasions and applications. Velcro is an interlocking connection system composed of hooks and velvet, and has the following functions: fixing and connecting: the hooks and velvet of Velcro can adhere to each other, providing powerful fixing and connecting functions. It can form good adhesion on the surface of objects, so that objects are firmly connected to each other. Another important feature of Velcro is that it is reusable. It can maintain good adhesion after multiple separations and connections. This makes Velcro very suitable for occasions that require frequent disassembly and reassembly, such as clothing, shoes, furniture and other decorations, and the use of Velcro is very simple and convenient. Just align the hooks and velvet and apply a little pressure to achieve adhesion. Compared with other fixing methods (such as buttons, zippers, etc.), hook and loop Velcro is easier to operate and use. The interlocking structure of hook and loop Velcro can provide a certain shock absorption and shock reduction effect. In the case of moving objects or undergoing vibration, hook and loop Velcro can reduce the transmission of shock and vibration and provide additional protection. The function of hook and loop Velcro is to provide fixing and connection functions. It is reusable, simple and easy to use, and can also provide a certain shock absorption and shock reduction effect.

[0032] Optionally, the structure of the reset nailing pliers body 1 is set to a vise shape. The role of setting the vise shape is that the special shape of the vise usually has a curved or toothed design, which can increase the clamping force. This shape can provide a more secure clamping, ensuring that the clamped object does not slide or move. Therefore, the vise is very useful in work that requires strong clamping, such as processes such as metal processing, welding and turning, and the shape design of the vise also helps to provide a more stable clamping. Its special geometric shape can disperse the applied force when clamping, making the clamping more uniform. This can reduce the risk of deformation or deformation of the object and ensure stability and safety during the clamping process. Another role of the vise shape is to provide a wider adaptability. They often have an adjustable clamping range or a variety of clamping positions to accommodate objects of different sizes and shapes. This flexibility enables the vise to cope with various work requirements and provide more usage options. The shape design of the vise usually also takes into account the convenience of operation. For example, some vises may have handles or knobs to make it easier to clamp and release. Such a design can improve work efficiency and reduce fatigue during use. In general, the shape of the vise is designed to provide a stronger and more stable clamping ability, increase stability, adapt to different work needs, and provide ease of operation. This makes the vise an important tool in many work situations.

[0033] Working principle: During specific use, the utility model is a kind of fracture reduction nailing pliers. When used by medical staff, they first contact the connecting block 5 inside the base arranged on the main body 1 of the reduction nailing pliers, and lift the screw rod 7 upward from the side slot by turning the handle 8. At this time, the screw rod 7 can be rotated by the rotating shaft, and the nailing pliers 12 can be used to gently drive the nail into the specific position of the patient's designated bone. The hook and velvet Velcro column 14 is arranged inside the clamp groove 13 and the hook and velvet Velcro is adhered to each other to protect the surface of the patient's bone from damage, which greatly improves the convenience of medical staff. The structural design is simple and the practicality is greatly improved.
