This utility model provides a hat cover height adjustment device and a sock machine, including an upper column, a lower column, and a fixing component. The upper column is connected to the hat cover and is located above the lower column. The fixing component is disposed on the upper and lower columns. The upper end of the lower column is provided with a second inclined surface. The upper column moves a certain displacement along the second inclined surface and is then fixed by the fixing component, thereby realizing the height adjustment of the hat cover. The fixing component includes a support part and a tightening part. The support part is connected to the tightening part. The support part limits and supports the upper column, and the tightening part fixes the upper column. This utility model allows for convenient adjustment of the hat cover height by moving the upper column a certain displacement along the second inclined surface at the upper end of the lower column and fixing it with the fixing component. Furthermore, it effectively solves the problem of parallelism error in the processing and assembly of the hat cover in the prior art, improving the product qualification rate.
