[0008] As a further solution of the utility model: the driving mechanism includes a turntable, the turntable is in rotational contact with the bracket, and a plurality of connecting blocks are fixedly connected to the contact surface between the bracket and the turntable, and the connecting blocks extend into the turntable and are in sliding contact with the turntable.

[0009] As a further solution of the utility model: a handle is fixedly connected to one end of the turntable, a card slot is opened inside the turntable, the card slot is inclined, and the card slot cooperates with the fixing device.

[0010] As a further solution of the utility model: the fixing device includes a moving rod, the moving rod passes through the card slot, the moving rod is in sliding contact with the bracket, a guide groove is opened inside the bracket, one end of the moving rod extends into the guide groove, the other end of the moving rod is fixedly connected to a connecting rod, and the other end of the connecting rod is fixedly connected to a fixing piece.

[0011] As a further solution of the utility model: the impact device includes an impact rod, one side of the impact rod is fixedly connected to a support rod, the other end of the support rod is fixedly connected to a slider, the slider is in sliding contact with the bracket, a limiting slide groove is provided inside the bracket, and the slider is located in the limiting slide groove.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: when the device is used, the handle is turned, the handle drives the turntable to rotate, and the turntable drives the slot to rotate. Since the slot is inclined, the guide groove limits the moving rod so that it can only move vertically, and the moving rod passes through the slot. The moving rod is in sliding contact with the turntable, that is, when the turntable drives the slot to rotate, the turntable squeezes the moving rod to make the moving rod move vertically, and the moving rod drives the fixing part to fix the fan through the connecting rod, and then pushes the impact rod, that is, the slider drives the impact rod to impact the fan main shaft through the support rod. The device can prevent the fan from shaking, facilitate the impact on the fan main shaft, and improve the efficiency of disassembling the fan main shaft. BRIEF DESCRIPTION OF THE DRAWINGS
