[0023] Please see Figure 1-3 A leather processing punching device with adjustable punching size includes a mounting frame 1, with multiple punching rods 2 mounted on the upper end of the mounting frame 1, and punching heads 3 mounted on the lower end of the punching rods 2. It also includes: a spring; a through tube 4 fixedly connected to the lower part of the punching rod 2; a spring 5 mounted in the middle of the surface of the through tube 4; a ball bearing 6 mounted at the lower end of the spring 5; a limiting ring 7 at the lower end of the ball bearing 6; a movable buckle 9 movably connected to the side end of the through tube 4 corresponding to the position of the limiting ring 7; a connecting tube 10 mounted inside the through tube 4; an annular groove 11 on the surface of the connecting tube 10 corresponding to the position of the limiting ring 7; and a fixed mounting component mounted on the lower end of the connecting tube 10 for fixing the structure of the punching head 3. The fixing component enables quick replacement of the punching head 3, improving work efficiency and ease of operation. Simultaneously, the design of the fixing component and the shock-absorbing spring ensures the stability and safety of the punching head 3 during replacement.

[0024] Furthermore, a fixed plate 12 is fixedly connected inside the punching rod 2. A shock-absorbing spring 13 is fixedly connected to the center of the lower end of the fixed plate 12, and the other end of the shock-absorbing spring 13 is fixedly connected to a first cone block 14. A second cone block 15 is provided at the lower end of the first cone block 14, and a limiting spring 16 is fixedly connected to the lower end of the second cone block 15. The lower end of the limiting spring 16 is fixedly connected to the bottom end of the punching head 3. The first cone block 14 and the second cone block 15 facilitate the positioning of the connecting tube 10.

[0025] Furthermore, the surface of the through tube 4 is provided with holes, and the holes are gradually reduced in size from the center to the outside. Ball bearings 6 are installed inside the holes. When the ball bearings 6 are in the inner part of the holes, they fix the connecting tube 10.

[0026] Furthermore, a protrusion is provided on the inner side of the movable buckle 9, and a clip is provided on the upper end of the protrusion. The clip is installed inside the ball bearing 6 to fix the movable buckle 9 and prevent the movable buckle 9 from moving out of the range.

[0027] Furthermore, a limiting block 8 is installed at the connection between the lower half of the punching rod 2 and the mounting frame 1. The limiting block 8 is installed at the connection between the lower half of the punching rod 2 and the mounting frame 1 to limit the movement range of the punching rod (2) and ensure its stability during operation.

[0028] Furthermore, the fixing components include a through tube 4, a spring 5, a ball bearing 6, a limiting ring 7, a limiting block 8, a movable buckle 9, a connecting tube 10, and an annular groove 11. The lower half of the punching rod 2 is fixedly connected to the through tube 4. The spring 5 is installed in the middle of the surface of the through tube 4, and the ball bearing 6 is installed at the lower end of the spring 5. The limiting ring 7 is set at the lower end of the ball bearing 6. The movable buckle 9 is movably connected to the side end of the through tube 4 corresponding to the position of the limiting ring 7. The connecting tube 10 is installed inside the through tube 4, and the annular groove 11 is set on the surface of the connecting tube 10 corresponding to the position of the limiting ring 7. The punching head 3 is fixedly installed at the lower end of the connecting tube 10. The through tube 4, spring 5, ball bearing 6, limiting ring 7, movable buckle 9, connecting tube 10, and annular groove 11 are used to fix and support the punching head 3, ensuring its stability and accuracy during the punching process.

[0029] Working principle: When the punching device is stationary, the punching rod 2 is securely mounted on the mounting frame 1 by a fixing component. The limiting block 8 restricts the initial position of the punching rod 2 to prevent accidental movement. When the punching rod head 3 needs to be replaced, push the movable buckle 9 upward. The protrusion inside the movable buckle 9 disengages from the ball 6. The lower end of the movable buckle 9 presses against the spring 5, the pressure on the ball 6 is released, and the ball 6 leaves the annular groove 11. Take out the punching head 3, remove the punching head 3 that needs to be replaced, and align the connecting tube 10 on the punching head 3 with the through tube 4. At the center, the connecting tube 10 is inserted. The upper end of the second cone block 15 collides with the first cone block 14. The shock-absorbing spring 13 is compressed, which in turn generates a rebound force on the connecting tube 10, causing the connecting tube 10 to reach a certain position. The movable buckle 9 is released, and the spring 5 unfolds to generate a rebound force on the movable buckle 9. The limiting ring 7 prevents the movable buckle 9 from sliding out of the range. The movable buckle 9 exerts pressure on the ball 6, and the movable buckle 9 pushes the ball 6 to move inward. While the ball 6 moves inward, a part of the ball 6 enters the interior of the annular groove 11, thereby fixing the ball 6 to the annular groove 11.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
