On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0030] In this embodiment, the top end of the housing 11 is provided with a cooling hole (not shown in the figure), which communicates with the inside of the housing 11, ensuring that the cooling fan 15 can effectively exhaust the heat generated by the vertical transmission motor 13 from the housing 11, thereby avoiding the accumulation of heat inside the housing 11.

[0031] Furthermore, in this embodiment, the vertical transmission assembly 10 also includes a plurality of guide rods 16 fixedly connected inside the housing 11. The guide rods 16 are arranged parallel to and spaced apart from the lead screw 12, and the guide rods 16 are slidably connected to the adapter block 14, which can effectively ensure that the lead screw 12 and the adapter block 14 remain stable when moving relative to each other, thereby improving the reliability of the overall transmission.
