Fig. 1 is a schematic view of a first embodiment of the present application, which includes a central shaft 100 and a sleeve that is sleeved outside the central shaft 100 and sequentially arranged from bottom to top: the device comprises a rotating mechanism, a jacking mechanism and a fixed supporting mechanism; the rotating mechanism is clamped at the bottom end of the central shaft 100; the jacking mechanism comprises an oil cylinder body 200, a vertical telescopic locking piston 210 is arranged in the oil cylinder body 200, the fixed supporting mechanism comprises a support 300, an elastic locking sheet 220 is arranged at the lower edge of the support 300 corresponding to the locking piston 210, the locking sheet 220 is sleeved on the periphery of the central shaft 100 and is fixedly connected with the central shaft 100, and a set distance is reserved between the locking sheet 220 and the locking piston 210 in a natural state.

In this embodiment, the central shaft 100 is connected to the jacking mechanism and the fixing and supporting mechanism in a clamping manner, and a gap with a predetermined distance is left between the inner side of the jacking mechanism corresponding to the central shaft 100 and the inner side of the fixing and supporting mechanism corresponding to the central shaft 100 in a natural state. In this embodiment, the housing of the support 300 is fixed above the housing of the cylinder body 200, and the two housings do not move relative to each other all the time.

In a preferred embodiment, a work holder seat 600 is provided above the support 300 corresponding to the top end of the central shaft 100.

When the workpiece 700 to be processed is fixedly processed, the locking piston 210 inside the cylinder body 200 extends and moves in a direction close to the support 300 until the end of the locking piston 210 is in abutting contact with the locking sheet 220 at the lower edge of the support 300, that is, a gap between the inner side of the jacking mechanism and the inner side of the fixed supporting mechanism disappears, the inner side of the jacking mechanism is in abutting contact with the inner side of the fixed supporting mechanism, and under the action of friction force when the end of the locking piston 210 is in abutting contact with the surface of the locking sheet 220, the locking piston and the locking sheet do not move relatively, and the rotating mechanism is controlled to be stationary at the moment, so that the central shaft 100 fixedly connected with the locking sheet 220 is stationary and does not rotate between the jacking mechanism and the fixed supporting mechanism, the fixed connection between the central shaft 100 and the fixed supporting mechanism for mounting the workpiece 700 to be processed is stably fixed for processing.
