Description
Technical Field
[0001] The invention relates to the technical field of oar shaft punching, and in particular to an automatic oar shaft punching mechanism with simple structure, high punching efficiency, high punching precision and labor saving. Background Art
[0002] As we all know, a paddle is a rowing tool that propels a boat forward. The paddle uses the principle of a forceful lever to simulate the pectoral and pelvic fins of a fish. During the paddling process in the water, the paddle can propel the boat forward through the reaction force of the water waves. The paddle generally includes a paddle shaft and a paddle blade. The paddle shaft is plugged into and fixed to the tail end of the paddle blade. The paddle shaft is generally configured as a telescopic or plug-in paddle shaft. Adjacent telescopic or plug-in paddle shafts are generally fixed by marbles. Circular holes for the marbles to engage need to be punched out on the paddle shaft. In order to ensure the overall feel of the paddle shaft, the circular holes are generally provided on the paddle shaft where the paddle blade is installed. In order to ensure that the circular holes are on the axis of the paddle blade, it is generally necessary to manually align them by feel. In this way, there is an error between the circular hole and the axis of the paddle blade, which affects the feel of the operator in the later stage. Summary of the Invention
