[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Reference Figure 1 and Figure 2 The utility model discloses a trigger type plug-in head, comprising a mounting body 1, a plug-in head 3, an extrusion piece 4, a trigger 5 and a lever 6.

[0027] A set of pistol grips 2 are provided on the installation body 1. The pistol grips 2 can be integrally formed with the installation body 1, or the pistol grips 2 and the installation body 1 can be assembled after being separately formed.

[0028] Among them, there is an air channel inside the plug head 3, and the socket end of the plug head 3 can be connected to the socket of the medical gas terminal to introduce the gas into the user or gas-using equipment. The other end of the plug head 3 opposite to the socket end is arranged in the installation body 1.

[0029] The extrusion piece 4 can be slidably arranged on the installation body 1 parallel to the axial direction of the plug head 3 . The extrusion piece 4 is used to extrude the gland (decorative cap). Therefore, the extrusion piece 4 can be a group of sliders slidably connected to the installation body 1 .
