[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a technical solution to solve the existing problems raised in the background technology.

[0021] Combined with Figure 1-4It can be known that the device includes a valve stem body 1, which is divided into a threaded rod section 1.1 and a connecting rod section 1.2. A threaded sleeve 2 is rotatably provided on the outer side of the threaded rod section 1.1, a threaded groove is provided on the outer side of the threaded sleeve 2, a connecting component 3 is rotatably provided on the inner side of the bottom end of the threaded sleeve 2, a plurality of plug-in grooves 1.3 are provided on the upper side of the connecting rod section 1.2, and the connecting component 3 includes a plurality of plug-in rods 3.1, which are plugged into the plug-in grooves 1.3.
