In this embodiment, preferably, the driving portion 6 includes a driving rod body 6.1, the driving rod body 6.1 is rotatably connected in the cylindrical channel 5.2, a rotary driving member 6.2 is disposed at one end of the driving rod body 6.1, which is located at the outer side of the housing 1, the rotary driving member 6.2 can rotate to enable the driving rod body 6.1 to move in the cylindrical channel 5.2, the end portion of the driving rod body 6.1 can press the sliding rod 5.2 to move, the sliding rod 5.2 moves to elastically press the bonding portion, so that the fitting part fits the nose of the user, the telescopic part comprises a plurality of elastic balls 5.5 arranged between the end part of the driving rod body 6.1 positioned in the cylindrical channel 5.2 and the sliding rod 5.2, the elasticity of the elastic balls 5.5 and the elasticity of the spring part 5.4 are both very small, therefore, when the muscles of the nose move, the sliding rod 5.2 can press the elastic ball 5.5 to deform, so that the gasket main body 2 can move elastically along with the movement of the nose of a user.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
