Abstract

The invention comprises a pneumatic tool, a leakproof piston, a male joint and a bolt. At the bottom port of the pneumatic tool is disposed an internal screw hole. At the bottom of the pneumatic tool is disposed a spring-holding hole, in which is held an elastic element. One end of the leakproof piston contacts with an elastic element and the other end is connected with the male joint. One spherical end of the male joint contacts with the leakproof piston and the other end passes through the bolt. The bolt is fixed in the internal screw hole at the bottom port of the pneumatic tool.

Description

technical field

[0001] The invention relates to an air inlet of a pneumatic tool, in particular to a combination of an air inlet of a pneumatic tool and a male joint of a quick connector so that it can be directly and quickly fitted with a female connector of the quick connector, and has 360-degree rotation and a suitable Angular deflection function. Background technique

[0002] Commonly used pneumatic tools are shown in Figures 4 to 7, including an air dust blowing gun 11 (as shown in Figure 4), a pneumatic grinder 12 (as shown in Figure 5) or a paint spray gun 13 (as shown in Figure 6). ) ... etc., the air inlet 14 at the end must be screwed with a male connector 15 of a quick connector, and the male connector 15 can be quickly fitted or quickly disengaged with the female connector 17 screwed on the air pipeline 16 (as shown in Figure 7 shown). Generally, any kind of pneumatic tool often needs to be rotated when it is used, and it often happens that the air pipeline 16 ...
