After the storage vehicle 4 storing the workpiece is moved into the machining chamber 1, the movable plate 7 is moved to drive the limiting block 8 to move inward, so that the limiting block 8 limits the movable wheel 5 of the storage vehicle 4, thereby avoiding the movement of the storage vehicle 4.

[0029] In addition, sliding grooves 10 are formed on both sides of the top of the bottom plate 6, and the movable plate 7 is in sliding fit with the sliding grooves 10, so that the sliding grooves 10 guide the movement of the movable plate 7, thereby stably moving the movable plate 7 to drive the limiting block 8 to limit the movable wheel 5 of the storage vehicle 4.
