The elastic tensioning piece I refers to a spiral spring or a rubber elastic sleeve.
The second elastic tension member is a spiral spring or a rubber elastic sleeve.
The working process of the present invention is as follows.
1) The poster roller is taken down, the medical science popularization poster to be posted is rolled on the outer cylindrical surface of the middle part of the poster roller, one end of the medical science popularization poster roll, which is observed from top to bottom, points to the clockwise direction, and the back surface of the medical science popularization poster faces outwards.

3) The relative angle between the extension bar and the connecting bracket is determined according to the height of an operator, the height of the part to be pasted in the publicity column, the horizontal distance and the like, and the extension bar and the connecting bracket are fixedly connected into a whole by using a clamping screw.
4) The medical science popularization poster is rolled up the back of the free end of the outside and is pasted on the publicity column through the tail end of the double-sided adhesive tape, the free end of the medical science popularization poster is not free, and the roller also leans on the publicity column. The existence of the roller component can facilitate the direction holding and can not be inclined leftwards or rightwards.
5) The operator moves the footfalls to the left and translates the invention as a whole to the left. The scroll wheel passively scrolls along the billboard. The end of the medical science popularization poster rotates with the medical science popularization poster and the poster roller assembly, and the end of the medical science popularization poster winds away. The medical science popularization poster rolls up and drives the fixed roller to rotate by means of friction force, and the fixed roller drives the movable roller and the isolation paper clamped between the movable roller and the fixed roller to operate by means of friction force. The linear velocity of the double-sided adhesive tape pasted on the publicity column relative to the connecting support, the rotary linear velocity of the outermost layer of the medical science popularization poster, the rotary linear velocity of the surface of the fixed roller and the linear velocity of the separation paper clamped between the fixed roller and the movable roller are equal, namely the double-sided adhesive tape can be synchronously stripped while being wound and separated, the separation paper is conveyed to the surface far away from the publicity column, and the separation paper is prevented from interfering with work.

The diameter of the roll rolled by the medical science popularization poster is smaller and smaller, the combination of the roll rolled by the medical science popularization poster and the poster roll still depends on the fixed roll under the action of the tension of the elastic tensioning member I, although the angular speed of the poster roll is increased, the linear speed of the double-sided adhesive tape attached to the publicity column relative to the connecting support, the rotational linear speed of the outermost layer of the medical science popularization poster, the rotational linear speed of the surface of the fixed roll and the linear speed of the part of the isolation paper clamped between the fixed roll and the movable roll are still equal. And stopping the step of the operator until the medical science popularization poster is completely unfolded and attached to the part to be posted in the publicity column.
6) The trigger is pulled, the trigger swings downwards around the lengthening rod-trigger hinge, the trigger pulls the brake cable, the brake cable passes through the spool, the brake cable transmits pulling force to the pressure spring guide post through the movable knife connecting wire, the movable knife overcomes the pressure of the pressure spring and translates along the movable knife sliding groove, the movable knife does shearing movement relative to the fixed knife, and the double-sided adhesive tape is sheared and cut off.
7) When the trigger is released, the pressure spring pushes the movable knife, the movable knife connecting wire, the brake cable and the trigger to reset, and the operation is finished after the pull-type switch is taken down.
The invention has the beneficial effects that: need not step on the height just can paste the medical science popularization poster on the publicity column of eminence, the operator does not have the risk of falling, convenience safe in utilization.
