In this embodiment, the inner tube 3 is cylindrical, and the inner wall is smooth, and a sealing ring is installed around the plug 51 of the piston 5, so that the inner wall of the inner tube 3 can slide smoothly while sealing is realized, and the flexibility of operation is improved. The inner tube 3 and the push rod 52 of the piston 5 form a piston type extrusion device; the sealing structure 1 is made of silica gel material, one end of the sealing structure is open, the sealing structure is sleeved on the discharge hole 21, at least one slit (which can be in a shape of a Chinese character 'yi' or a cross) is slipped out of the other end surface of the sealing structure, two edges of the slit are attached together in a natural state (without stress), pigment can be spread out in a stress state, and the sealing structure is elastically sealed by using silica gel.

Preferably, a step 31 is arranged on the outer wall of the inner tube 3, and the part from the open end of the inner tube 31 to the step 31 is provided with external threads matched with the outer tube 4; the end cap 2 is detachably connected to the step 31.

Preferably, the end cap 2 has an end surface for enclosing a pigment cavity, and in one embodiment of the present invention, the end surface is a plane, and the discharge port 21 is disposed on the end surface; the end face, the inner tube 3 and the plug 51 of the piston 5 are jointly enclosed to form a pigment cavity; the piston 5 moves axially along the inner tube 3 under the action of external force and is used for extruding the pigment in the pigment cavity from the discharge hole 21; the top surface of the plug 51 (on the side of the paint cavity) mates with the end surface.

When the device is used, the outer tube 4 is rotated, the outer tube 4 drives the piston 5 to move relative to the inner tube, the plug 51 of the piston 5 extrudes pigment in the pigment cavity, and when the pigment is extruded, the pigment flows out of a gap of the silica gel head of the device and directly flows into the pigment box disc for a user to use. The top surface of the plug 51 (the surface located in the pigment cavity) is matched with the end surface to enable the pigment in the pigment cavity to be extruded from the gap of the silica gel sealing structure as far as possible in the extruded state, so that the material waste is avoided.

Preferably, an annular sliding limiting structure is arranged between the push rod 52 and the bottom cover 6. Since the piston 5 is in a static state due to static friction force between the plug 51 and the inner tube 3 during rotation of the outer tube 4, in order to prevent the push rod 52 of the piston 5 from being stressed in other directions (directions other than axial thrust) along with the action of the outer tube 4, so that the plug 51 and the inner tube 3 are not smooth in movement (so as to cause unsmooth pigment generation) or the two matching parts are stressed and deformed, the annular limiting structure has the function of limiting the relative movement track between the piston and the outer tube 4 and preventing the push rod 52 from being stressed in a non-axial direction during rotation of the outer tube 4.

The piston 5 needs to be overlapped with the central axes of the outer tube 4 and the inner tube 3, the higher the overlap ratio is, the better the performance of the structure is, including the aspects of flexibility of operation, service life and the like, and the structure can reduce the centering installation error among the three.

Preferably, a rotation bolt 7 is mounted on the bottom cover 6 (a bearing is mounted between the bottom cover 6 and the rotation bolt 7), one end of the rotation bolt 7 passes through the bottom cover 6 from bottom to top and then is detachably connected (in threaded connection or plug connection) with the push rod 52, and the other end is located at the lower part of the bottom cover 6.

Preferably, the portion 71 of the rotation bolt 7 extending into the outer tube 4 is screwed with the push rod 52, and the portion of the rotation bolt 7 located outside the outer tube 4 forms a manual knob 72 for manual rotation operation.

When the manual knob 72 is screwed, the ball pushes the piston push rod to push and squeeze pigment, power is transmitted between the manual knob and the piston push rod 52 through the ball, and friction between the manual knob and the piston push rod is rolling friction, so that friction force is small.
