Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

The embodiment is shown in the attached drawings 1-3 of the specification, the pollution-preventing couplant smearing head comprises an extrusion sleeve 1 and a couplant bottle 2, wherein the couplant bottle 2 is screwed on the extrusion sleeve 1, and the extrusion sleeve 1 and the couplant bottle 2 are provided with auxiliary structures;

the auxiliary structure includes: an isolation protection part, an inner rod 3 and an extrusion part;

the isolation protection part is arranged at the bottom of the extrusion sleeve 1, the inner rod 3 is fixed in the couplant bottle 2, and the extrusion part is arranged on the couplant bottle 2.

The isolation protection part includes: the clamping groove 4, the isolating sleeve 5, the round hole 6 and the clamping block 7;

the clamping groove 4 is formed in the outer surface of the extrusion sleeve 1, the round hole 6 is formed in the bottom surface of the round hole 6, the fixture block 7 is arranged on the inner wall of the isolation sleeve 5, and the isolation sleeve 5 is fixed in the clamping groove 4 through the fixture block 7.

The extrusion section includes: the extrusion air bag 8, the extrusion plate 9 and the sealing ring 10;
