[0008] The outer cylinder is detachably arranged on the inner cylinder, and the inner wall of the outer cylinder is provided with clamping holes on both sides.

[0009] When the roving tube needs to be replaced, the outer cylinder is moved upward by personnel, at which time the clamping column moves from the clamping hole to the inner cylinder direction, the two plate bodies of the V-shaped elastic plate move towards the middle, until the outer cylinder is taken off from the inner cylinder, and then a new outer cylinder is inserted into the inner cylinder.

[0010] One preferred scheme is that the outer wall of the upper end of the outer cylinder is provided with a Velcro.

[0011] A preferred solution is that the engaging members have two groups, and the two groups of engaging members are arranged at upper and lower positions in the inner cylinder respectively, and the upper and lower positions of the inner wall of the outer cylinder are respectively provided with clamping holes.

[0012] A preferred solution is that the upper end of the base is arc-shaped.

[0013] A preferred solution is that the upper end of the base is arc-shaped.

[0014] A preferred solution is that the upper end of the base is arc-shaped. BRIEF DESCRIPTION OF DRAWINGS
