[0028] Example:

[0029] Please see Figures 1-4 A cotter pin installation aid includes a mounting bracket 1. The front end of the mounting bracket 1 has a through hole 2. The inner end of the through hole 2 is engaged with a cotter pin body 3. An auxiliary component is sleeved on the outer end of the cotter pin body 3. The auxiliary component includes an auxiliary crossbar 5. The auxiliary crossbar 5 is located at the turning point of the cotter pin body 3. A transverse through hole 10 is opened at the connection between the auxiliary crossbar 5 and the cotter pin body 3. Magnetic upper slots 8 are symmetrically opened at the upper and lower ends of the auxiliary crossbar 5. A strong magnetic cylinder 9 is placed in the inner end of the magnetic upper slot 8. The two strong magnetic cylinders 9 are magnetically connected to the upper and lower ends of the cotter pin body 3, respectively. A circular striking plate 6 is fixedly connected to the end of the auxiliary crossbar 5 away from the cotter pin body 3. Several anti-corrosion coatings are evenly applied to the outer end of the auxiliary component.

[0030] Please see Figures 1-4A replaceable reinforcing plate 7 is provided at the end of the circular striking plate 6 away from the cotter pin body 3. An inner groove ring 13 is provided at the end of the circular striking plate 6 near the replaceable reinforcing plate 7. Multiple buffer spring horizontal members 11 are fixedly connected to the inner sidewall of the inner groove ring 13. The multiple buffer spring horizontal members 11 are arranged in a ring at equal intervals. A spherical buffer member 12 is fixedly connected to the end of the buffer spring horizontal member 11 near the replaceable reinforcing plate 7. The spherical buffer member 12 is connected to the inner sidewall of the replaceable reinforcing plate 7. Multiple threaded external grooves 14 are provided on the outer side of the end of the replaceable reinforcing plate 7 near the circular striking plate 6. The threaded external grooves 14 are threadedly connected to the inner sidewall of the inner groove ring 13. Multiple arc-shaped external rods 4 are provided at the front end of the cotter pin body 3. The multiple arc-shaped external rods 4 are arranged in a horizontally equidistant manner. Multiple reinforcing vertical ribs 15 are fixedly connected to the outer side of the replaceable reinforcing plate 7. The multiple reinforcing vertical ribs 15 are arranged at equal intervals.

[0031] Please see Figures 1-4 This cotter pin installation aid mainly consists of a mounting bracket 1, a cotter pin body 3, and auxiliary components fitted onto the outer end of the cotter pin body 3. During cotter pin installation, the outer end of the cotter pin body 3 is first engaged with the inner end of the through hole 2 at the front end of the mounting bracket 1, completing the initial connection. At this time, the auxiliary components work together through the magnetic connection between the auxiliary crossbar 5 and the cotter pin body 3. The operator can use tools to strike the circular striking plate 6 or the replaceable reinforcing plate 7. The striking force is transmitted to the cotter pin body 3 through these components. Because the circular striking plate 6 provides a larger point of force, the striking operation is more precise and effective, allowing the cotter pin body 3 to be accurately installed in the predetermined position. If impact force is generated during the striking process, the replaceable reinforcing plate can be used. The impact force on plate 7 is transmitted to the buffer spring cross member 11 through the spherical buffer member 12. The buffer spring cross member 11 absorbs and buffers the impact force through elastic deformation, preventing the impact force from damaging the internal components of the device. When it is necessary to remove the cotter pin, the magnetic connection between the auxiliary cross member 5 and the cotter pin body 3 can be removed, and an appropriate external force can be applied to make the cotter pin body 3 detach from the through hole 2. During this process, the arc-shaped outer rod 4 may play a role in stabilizing the cotter pin body 3 or providing an additional point of force, which facilitates the smooth operation. The anti-corrosion coating on the outer end of the auxiliary component effectively prevents corrosion. The reinforcing vertical rib 15 enhances the strength of the replaceable reinforcing plate 7, ensuring that the entire disassembly process is stable and reliable, reducing damage to the cotter pin and surrounding components, and improving operational efficiency and safety.
