[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please refer to Figures 1 to 8As shown, the repair fixer with safety lock of this utility model includes: a fixer body 1; a first pin 13 is installed on the fixer body 1, and a handle 14 is installed on the fixer body 1 via the first pin 13; a locking pin 15 that can slide back and forth is installed inside the fixer body 1; the front and rear ends of the handle 14 are respectively provided with a limiting groove 143 and an arc-shaped sliding groove 144, the handle 14 is provided with a waist-shaped through groove, a second pin 141 is installed in the waist-shaped through groove, and a rebound rod 142 is installed inside the fixer body 1; the left end of the rebound rod 142 abuts against the right side of the second pin 141; the rear end of the locking pin 15 moves in the arc-shaped sliding groove 144, and the front end of the locking pin 15 is fitted in the limiting groove 143; the locking pin 15 is made of metal and its surface is plated with a nickel-chromium alloy layer.

[0031] In this embodiment of the invention, a storage seat 12 is screwed into the internal thread of the fixture body 1. A movable rod 121 is installed inside the storage seat 12, and the left end of the movable rod 121 contacts the right side of the handle 14. When the handle 14 is pressed or rotated under external force, the movable rod 121 will be squeezed by the right side of the handle 14 and retract into the storage seat 12. When the external force is removed, in conjunction with the elastic force of the rebound rod 142, the movable rod 121 can push the handle 14 in the opposite direction, helping it to quickly return to its initial position, ensuring the continuity and convenience of the operation of the handle 14, and reducing the trouble of manual reset.

[0032] In this embodiment of the invention, the main body 1 of the fixture is provided with anti-slip texture 11, which is a strip-shaped groove structure. The anti-slip texture 11 can improve the stability during operation and prevent the hand from slipping.

[0033] In this embodiment of the invention, the handle 14 is a plastic part, injection molded. Plastic has a lower density, which significantly reduces the overall weight of the fixture compared to a metal handle 14, making it easier for operators to hold and use for extended periods and reducing hand fatigue.

[0034] In this embodiment of the invention, a hook 16 is provided at the upper end of the main body 1 of the fixation device. When the repair fixation device is not in use, it can be hung on a tool rack, wall hook, or other places by the hook 16 to avoid loss or damage caused by random placement, while also saving storage space.

[0035] In Example 2, based on Example 1, a locking sleeve 21 is threaded onto the left end of the fixture body 1. The outer wall of the locking sleeve 21 is knurled with straight knurling, and a sealing gasket is provided on the contact surface between the locking sleeve 21 and the fixture body 1. A nail tube 2 is installed inside the locking sleeve 21, and the nail tube 2 is locked onto the fixture body 1 by the locking sleeve 21. The locking sleeve 21 and the fixture body 1 are connected by threads, which can firmly clamp the nail tube 2 between them, ensuring that the nail tube 2 will not loosen or shift during operation, and facilitating the replacement of nail tubes 2 of different specifications according to different repair needs, thus improving the versatility and practicality of the fixture. The straight knurling design on the outer wall of the locking sleeve 21 increases the friction between the hand and the locking sleeve 21, allowing the operator to easily tighten or loosen the locking sleeve 21 without the need for additional tools, quickly completing the installation and removal of the nail tube 2, saving operation time and improving work efficiency. The sealing gasket on the contact surface between the locking sleeve 21 and the main body 1 of the fixing device can effectively fill the gap between them, prevent dust, liquid and other impurities from entering the inside of the fixing device during operation, avoid internal parts from being worn or failing due to contamination, and extend the service life of the fixing device.

[0036] In Example 3, based on Examples 1 and 2, the nail tube 2 is made of stainless steel. The left end of the nail tube 2 has an external thread, and a locking ring 22 is screwed onto the threaded left end. A flexible tube 221 is fixed to the left end of the locking ring 22, and a tube head 222 is fixed to the left end of the flexible tube 221. A spring 223 is movably sleeved on the flexible tube 221, and a corrugated tube 224 is fitted onto the flexible tube 221, covering the spring 223. The flexible tube 221 is made of medical-grade silicone. The stainless steel nail tube 2, with its high strength and corrosion resistance, can withstand significant pressure and external force during repair work, ensuring it is not easily deformed or damaged when pushing repair materials or performing fixation operations. It also adapts to various working environments, extending its service life. The medical-grade silicone flexible tube 221 has good flexibility and biocompatibility. On the one hand, it can be flexibly bent according to operational needs, adapting to repair operations at different angles and in different spaces, ensuring that the tube head 222 can accurately reach the target position. On the other hand, the medical-grade material ensures safety when in contact with the human body or in sensitive environments, avoiding contamination or irritation. Simultaneously, the flexible tube 221 stably transmits the repair material or force delivered by the nail tube 2, achieving efficient repair. The spring 223, movably sleeved on the flexible tube 221, enhances the tube's resistance to bending, preventing excessive deformation and blockage or damage caused by frequent bending or stress. It also provides support when the tube 221 is straight, maintaining its shape stability. The corrugated tube 224 covering the spring 223 effectively protects both the spring 223 and the flexible tube 221 from external dust and debris, reducing wear and extending their service life.

[0037] When not in use, the locking pin 15 has its front end engaged in the limiting groove 143 of the handle 14, and its rear end movable in the arc-shaped sliding groove 144, thus locking the handle 14 and preventing accidental operation. When repair work is required, press the locking pin 15 backward to disengage its front end from the limiting groove 143, releasing the lock. At this time, the rear end of the locking pin 15 slides accordingly in the arc-shaped sliding groove 144. Then, operate the handle 14, which rotates around the first pin 13. Its right side will press the movable rod 121, causing the movable rod 121 to retract into the storage seat 12. Simultaneously, the right side of the handle 14 exerts pressure on the rebound rod 142, causing the rebound rod 142 to deform and store force. During the rotation of the handle 14, the second pin 141 moves in the waist-shaped through groove, providing guidance for the rotation of the handle 14. When the handle 14 is rotated to the appropriate position, it is held stably by the anti-slip texture 11 on the main body 1 of the fixator. At this time, the nail tube 2 is firmly installed on the left end of the main body 1 of the fixator through the locking sleeve 21. The straight knurling on the outer wall of the locking sleeve 21 makes it easy to operate its tightness. The absorbable nail is transmitted through the nail tube 2, enters the hose 221 through the locking ring 22. The hose 221 is made of medical grade silicone and can be flexibly bent. The spring 223 enhances its bending resistance. The corrugated tube 224 protects the internal structure. Finally, it acts on the repair site through the tube head 222. After the operation is completed, the handle 14 is released. The rebound rod 142 releases the elastic force to push the handle 14 back to the original position. The movable rod 121 is reset in the storage seat 12 and assists the handle 14 to return to the initial position. The locking pin 15 is pushed forward so that its front end is re-engaged into the limiting groove 143 to achieve re-locking. The hook 16 can hang and store the fixator.
