[0046] On the basis of the above structural arrangement, in order to prevent external objects from touching the turntable drive motor 63, a protective cover 64 is provided outside the turntable drive motor 63 for peripheral protection.

[0047] The above structure arranges the turntable drive motor 63 at the upper part and is of a fixed design, which can effectively prevent the pipeline from being entangled due to the interference of the turntable drive motor 63.

[0048] Embodiment 3:
