After the slide cylinder is adjusted to the completed position, the return spring will drive the positioning piece to press on the elastic rope due to its own elastic force, so as to position the V-shaped keel, prevent the V-shaped keel from sliding by itself, and improve the stability during use.

[0010] As a preferred subject of the utility model, the outer surface of the reset spring is provided with a waterproof film. Since there may be a lot of sweat on the head of a person, the rust rate of the reset spring can be effectively slowed down, thereby helping to extend the service life of the reset spring.

[0011] As a preferred embodiment of the subject of the utility model, the outer surface of the pulling block is provided with anti-skid patterns, which can increase the friction between the hand of the person and the pulling block, thereby helping to solve the problem of slipping when pulling the pulling block.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By pulling the elastic rope, the elastic rope can be stretched, and then the mask body is covered on the person's face. Then the elastic rope is released, and the elastic rope can be used to fix the mask body on the person's face due to its own elastic force. In this process, the slide tube slides on the elastic rope, and then the V-shaped keel drives the protective pad to be stuck on the upper edge of the person's ear, which can avoid the elastic rope from cutting, strangling, and pressure damage to the upper edge of the ear, thereby improving the comfort of the person;

[0015] 2. At the same time, by setting a reset spring, after the slide tube has adjusted its position, the reset spring can drive the positioning piece to press on the elastic rope due to its own elastic force, so as to position the V-shaped keel and prevent the V-shaped keel from sliding on its own, thereby improving the stability during use. By setting anti-slip textures, the friction between the personnel's hands and the pulling block can be increased, thereby helping to solve the problem of slipping when pulling the pulling block.
