Claims

[Scope of utility model registration request]

An extrusion port 4 is provided at the distal end of the cylinder 1 to form an application section 6, and a partition plate 12 having a through hole 13 is provided within the proximal end of the cylinder 1, and the inside of the cylinder 1 is formed into a non-circular shape. Partition plate 1
A cylindrical portion 14 having a circular interior is provided on the proximal end side of the cylinder 1, and a piston 31 formed into a non-circular shape corresponding to the shape inside the cylinder 1 is slidably fitted into the cylinder 1, and the piston 31 is fitted with the partition. Through hole 1 in plate 12
A bolt 32 passing through the cylinder 1 is connected to the cylinder 1, and a cylindrical body 21 containing the bolt 32 is rotatably connected to the base end of the cylinder 1.
A cylindrical nut 33 is rotatably provided in the cylindrical portion 14, and is screwed into the cylindrical nut 33 by passing through the cylindrical nut 33.
One protrusion 20 along the axial direction of the nut 33 is provided on either the outer circumferential surface of the outer peripheral surface of the nut 33 or the inner surface of the cylindrical portion 14, and a plurality of protrusions 20 are provided on the other at equal intervals. Side protrusion 20 and cylinder part 1
The protrusions 20 on the fourth side are in a positional relationship in which they come into contact with each other by the rotation of the nut 33 and ride over the other, and furthermore, the sliding member is biased by a spring 35 so as to pass through the bolt 32 and come into contact with the nut 33. The slider 34 is slidably provided in the cylinder body 21, and the nut 33 and the slider 34 are each provided with a plurality of chevron-shaped protrusions 41 that engage with each other, one side of each chevron-shaped protrusion 41 is a gentle slope 42, and the other side is vertical. Applicator formed as surface 43.
