The right surface of the limiting plate 20 is fixedly connected to the handle 21. The inner surface of the limiting plate 20 is slidably connected to the sliding rod 22. The right surface of the limiting plate 20 is fixedly connected to the spring 23. The right surface of the insertion box 18 is fixedly connected to the limiting seat 24.
