[0037] As a preferred embodiment of the utility model, the stamping mechanism 8 also includes a proximity switch 83, which is installed on the workbench. The proximity switch 83 is electrically connected to the pushing cylinder 7. A proximity block 84 that cooperates with the proximity switch 83 is provided on the pressure rod 82. When the pressure rod 82 presses the steel ball into the sleeve, the proximity block 84 is detected by the proximity switch 83. At this time, it means that the pressure rod 82 has been partially inserted into the sleeve, and there is no need for the pushing cylinder 7 to support and position the sleeve. The pushing cylinder 7 can be reset to the initial position at this time to push the next sleeve, thereby effectively improving the hole extrusion efficiency.

[0038] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto.
