When the connecting rod assembly 14 is used for extrusion, the top cover 12 is downwards placed upside down, the whole packaging tube is placed upside down, the connecting rod assembly 14 is respectively pushed downwards by two hands for extrusion, more residues are easy to generate at the transition position of the tube body edge part 111 and the hose body 11, and part of residues can be gathered towards the middle through inward extrusion of the track block 13, so that the connecting rod assembly 14 can extrude the residues conveniently. The rail block 13 is pressed in an inward rotation or the link assembly 14 is pressed in a translational upward direction, and both can be used independently or alternately.

As shown in fig. 5, a positioning block 15 is disposed at the bottom of the pipe edge 111, the positioning block 15 is made of plastic, the positioning block 15 includes a gap for fixing the rail block 13 on the meeting surface 151, the opening direction of the gap on the meeting surface 151 is located in the tangential direction of the rotation of the lower end of the rail block 13, and the lower end of the rail block 13 can be directly fastened into the positioning block 15 from the meeting surface 151 on the side of the positioning block 15 to be fixed after the rail block 13 rotates, so that the rail block 13 can be prevented from moving at will when the rail block 13 is not needed to be extruded.

The pressing head 133 may be integrated with the inner club head 1411 and the outer club head 1421, and pushing the pressing head 133 may instead push the inner club head 1411 and the outer club head 1421 to rotate the rail block 13. The specific operation is as follows:

the buckling end of the lower end of the track block 13 is loosened, and the inner rod head 1411 and the outer rod head 1421 of the connecting rod assembly 14 are pushed inwards and upwards simultaneously, so that the effect of extruding the hose body 11 upwards and inwards simultaneously is achieved, the buckling end of the lower end of the track block 13 can be fixed, and only the extrusion mode of upwards extruding the connecting rod assembly 14 is used, and the connecting rod assembly is selected according to actual use conditions.
