The rotation axis of tool housing setting is positioned in the square opening of driven wheel; The knob that turns clockwise, rotation axis drives driven wheel and turns clockwise, and driven wheel then drives two idle pulleys and rotates simultaneously; Produce slight frictional force between damping rubber circle on the driven wheel and the switching-over slide plate simultaneously; Because the active force that turns clockwise of driven wheel makes the switching-over slide plate draw close to clockwise direction, makes left idle pulley and the upper winding shaft gears engaged that is rotated counterclockwise and drive it to turn clockwise.In like manner, the counter-rotating driven wheel then can drive the lower winding shaft gear and do counter-rotating, thereby has so just realized driving the spool gears that the both sides different directions requires through the change of a knob direction of rotation.And be located at the damping rubber circle on the switching-over slide plate upper side, and then be used for the location, make being flapped toward of slide plate of switching-over remain consistent with power direction.In the whole roll film process, have only a pair of spool gears and idle pulley to be in engagement all the time.
Described upper and lower spool gears is shaped on spline respectively and is connected with the spline of two scroll cores upper end.
This utility model also comprises the two hollow spools that are enclosed within respectively on two scroll cores, all has axial narrow hole on the described spool, and spool upper end all is shaped on spline and is connected with spline on each self-corresponding scroll core.
When assembling scroll core and spool, the film termination is passed the narrow hole of scroll core and spool simultaneously, the scroll core and spool gears is pressed on the spline on the scroll core screwed again positions, and the termination of film is anchored in the spool.
Relative prior art, the beneficial effect of this utility model:
1, the rotation of corresponding film different directions only is provided with a drive knob, and is simple to operate; When knob was left-handed, film was to left movement, and during dextrorotation, film moves right, and more met people's daily logic, can effectively reduce the damage of the winding mechanism that maloperation causes.
2, cover plate is set, when stoping dust and other impurities to stop up gear, prevents that gear drive is squeezed, guarantee that winding mechanism safely and steadily runs.

Fig. 1 is the explosive view of this utility model preferred embodiment;
Fig. 2 is the another one visual angle of this utility model preferred embodiment explosive view;
When Fig. 3 turns left and right for knob, the gear drive local state sketch map of this utility model preferred embodiment.
The specific embodiment
Below, in conjunction with accompanying drawing this utility model is further described:
Like Fig. 1, shown in 2, the preferred embodiment of this utility model comprises: 1, two of framework has the scroll core 4,13 that axial narrow hole is respectively applied for the film winding operation two ends, is enclosed within two hollow spool 2,3, one gear drives on two scroll cores 4,13 respectively; Described two scroll cores, 4,13 lower end correspondences are bearing in the both sides of framework 1 inside, and scroll core 4,13 upper ends pass framework 1 end face and are connected with gear drive; Also all have axial narrow hole on the described spool 2,3, and spool 2,3 upper ends all are shaped on spline and are connected with the spline of each self-corresponding scroll core 4,13 upper end; Described framework 1 top face has a cover plate 12 through the connector fixed support, leaves the ccontaining described gear drive in space between cover plate 12 and framework 1 end face.
Described gear drive comprises driven wheel 10; Upper and lower spool gears 7,8; Be used to the to be connected with a joggle left and right idle pulley 5,6 of driven wheel and last or lower winding shaft gear, and a switching-over slide plate 11, the spline that described upper and lower spool gears 7,8 is provided with through the lower end connects the spline of two scroll cores, 4,13 upper ends respectively; Described left and right idle pulley 5,6 is bearing in respectively on two outstanding protruding axles of described switching-over slide plate 11; Described driven wheel 10 has mandrel, and the driven wheel 10 upper surface mandrels outsides is provided with and is used to make switching-over slide plate 11 to produce the damping rubber circle 14 of skew, and the mandrel lower end is bearing in the perforate of framework 1 end face, the upper end is passed switching-over slide plate 11 corresponding through holes and is bearing in the perforate of described cover plate 12; Described switching-over slide plate 11 upper sides are provided with the damping rubber circle 9 that is used to locate switching-over slide plate 11; Described mandrel upper end has square hole, so that insert a square shaft knob, thereby drives whole driving mechanism rotation.
