[0001] The utility model relates to the technical field of hoe-shaped connecting shaft processing, in particular to a fixing device for hoe-shaped connecting shaft processing. Background Art

[0002] As a common mechanical transmission device, the coupling is mainly used to connect two shafts so that they can transmit power under different working conditions. The working principle of the coupling is to connect the two shafts so that they can maintain synchronous movement during rotation, thereby achieving effective power transmission; the hoe-shaped connecting shaft is a connecting shaft with the shape of a hoe, and the connecting shaft is an inverted "T" shape, which expands the scope of use.

It is difficult to quickly clamp and secure the flat end and the shaft end of the hoe-shaped connecting shaft separately. The clamping stability is poor, and the hoe-shaped connecting shaft, due to its excessive length, can wobble, making machining inconvenient. Therefore, those skilled in the art have provided a fixture for machining hoe-shaped connecting shafts to address the issues raised in the background art. Utility Model Content
