使用思路为：
Timestamp->字符串->datetime.datetime

示例代码

import pandas as pd
from datetime import datetime


def convert_timestamp(this_date):
	"""转Timestamp为datetime.datetime"""
    target_date = datetime.strptime(this_date.strftime("%Y-%m-%d"), "%Y-%m-%d")
    return target_date


new_date = convert_timestamp(this_date=pd.to_datetime("2022-01-01"))
print(new_date, type(new_date))

得到结果：

2022-01-01 00:00:00 <class 'datetime.datetime'>
