我找到一种解决办法，虽然貌似有点繁琐，你自己看着办吧。。

from tkinter import *

        super().__init__()
        self.geometry(geo)

        self.tree = ttk.Treeview(self, )
        self.tree.pack()
        self.tree['columns'] = (1, 2, 3)
        self.tree['show'] = 'headings'
        self.tree.column(1, width=90, anchor='c')
        self.tree.column(2, width=90, anchor='se')
        self.tree.column(3, width=90, anchor='se')
        self.tree.heading(1, text='Name')
        self.tree.heading(2, text='Sex')
        self.tree.heading(3, text='Age')
        self.iid = self.tree.insert("", 'end', text ="item_1", values =("Bill", "M", "25"), 
                         tags=('d_click', 'test'))  # 为每条item添加tags，然后利用该tags来触发事件，如双击
                        #  https://tkdocs.com/tutorial/tree.html#appearance
        self.tree.tag_bind('d_click', '<Double-1>', lambda e:self.entry_popup(e))  

        self.tree.insert("", 'end', text ="item_2", values =("Caty", "M", "23"), 
                        tags=('d_click',)) # 同样给它打上一个“双击”的标签

        # self.tree.bind("<Double-1>", lambda e: self.entry_popup(e))
        # self.tree.bind("<Double-1>", lambda e:self.d_click(e))

    def entry_popup(self, ev):
        self.tl = Toplevel(self.tree, )
        self.tl.title('输入弹窗...')
        self.tl.geometry(f"300x40+{ev.x_root}+{ev.y_root}")
        # self.tl.overrideredirect(True)
        self.ent = Entry(self.tl, borderwidth=2)
        self.ent.focus()
        self.ent.pack()
        curItem = self.tree.focus()
        item_val = self.tree.item(curItem)
        print(item_val)
        self.ent.insert(END, ','.join(map(str, item_val['values'])))
        self.ent.bind("<Return>", lambda e:self._input(self.ent.get()))
    
    def _input(self, entry_text):
        # print(entry_text)
        self.after(10, self.tl.destroy)
        focused = self.tree.focus()
        print(focused)
        x = entry_text.split(',')  # 根据 item的特点，输入逗号分隔的 name,sex,age 
        self.tree.insert('', str(focused)[1:], values=x)
        self.tree.delete(focused)  # 删掉原有的
