[0002] The shaft fixing device for the coil holder is mainly used to ensure the stability of the coil during processing or transportation. This device usually includes a mechanical structure that can be fixed and unlocked, allowing the coil to be easily loaded or unloaded when needed. Since the shaft fixing device in the related art does not have an adjustment function, when the diameter of the coil shaft to be installed changes, the shaft fixing device cannot switch between coils of different specifications. The locking mechanism is a crucial part of the shaft fixing device, which is responsible for locking the shaft firmly in the required position. Since the locking mechanism of the shaft fixing device in the related art is prone to wear, the locking force is weakened, or even the locking mechanism fails, affecting the stability and safety of the entire device.

[0015] Compared with the prior art, the rotating shaft fixing device for a coil support described in the utility model has the following advantages:

[0016] The utility model discloses a rotating shaft fixing device for a coil support, wherein the adjustable rotating shaft locking mechanism can adjust the distance between two arc-shaped pressing plates, thereby being able to adapt to the coil rotating shafts of different diameters, wherein the arc-shaped pressing plate is designed to adapt to the curved surface of the rotating shaft, provide uniform and adjustable pressure, thereby ensuring that the rotating shafts of different diameters can be stably and reliably locked. The buffer mechanism provides additional stability and buffering capacity for the rotating shaft fixing process.

Due to the rolling effect of the ball bearing, it can evenly distribute the pressure, avoiding local wear caused by concentrated pressure, so that even under long-term use, a high locking force can be maintained.

[0029] The adjustable shaft locking mechanism includes a locking screw 601, two arc-shaped pressure plates 501 and four guide pressure plates 502.
