Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, book is described further to the present invention.

Embodiment 1:

As shown in Figure 2, Figure 3, Figure 4, a kind of file, comprise base plate 2, crotch 1 and torsion spring 5, the both ends of the front side of described base plate 2 extend all forward and curl into the reel 3 with axis hole, described crotch 1 comprises the fixed part 11 being positioned at the rotating shaft 12 of both sides, front end, the connecting portion 13 of both sides, middle part and being positioned at rear end, the two ends of connecting portion 13 are connected with one end of corresponding rotating shaft 12 and wherein one end of fixed part respectively, the other end of rotating shaft 12 inserts axis hole and stretches out, and described torsion spring 5 is placed on rotating shaft 12, crotch 1 is hinged by torsion spring 5 and base plate 2; The other end of at least one rotating shaft 12 is provided with the rotating part 6 that can be used for rotating crotch 1.

When this file folder is fixed on after on certain backboard, in use, one hand just can control rotating part 6, during operation, under 4 fingers of tiger's jaw side are placed on backboard, thumb pressing rotating part 6, utilizes rotating part 6 to control whole crotch 1 and rotates the object that just can reach out folder, another hand can be used for putting file to reach effect easy to use, uses very laborsaving.Also the backboard being provided with file can be positioned over desktop, with the rotating part 6 of one hand pressing file, reach out the object of folder; The mode now driving folder changes into pressing rotating part by traditional stretch bending hook, and power thrusts changes, easy to use.

Further, the other end of described rotating shaft 12 is bent to form bent rod 4, and bent rod 4 is described rotating part 6; When the fixed part 11 of crotch 1 offsets with base plate 2, bent rod 4 is in tilting or vertical shape.

Adopt integral structure structure simple, and bent rod 4 structure easily realize, only need by the part bending exposing to axis hole of the other end of rotating shaft 12; And be under bent rod 4 normality or vertical state, nip bent rod 4 and base plate 2 or backboard with a hand and bent rod 4 just can be realized to rotate for rotating shaft with rotating shaft 12, while rotation, also achieve out folder.

Embodiment 2:

As shown in Figure 5, a kind of file, its structure is substantially the same manner as Example 1, difference is: the side of described rotating part 6 is provided with the trepanning 14 matched with the other end of rotating shaft 12, rotating part 6 and rotating shaft 12 are socketed, for improving the cooperate degree of trepanning 14 and rotating shaft 12, the cross section of the other end of trepanning 14 and rotating shaft 12 is all set to polygon; The front end of rotating part 6 is provided with press section 17.The present embodiment adopts external rotating part 6.

Pinch press section 17 and base plate 2 or back by hand, folder can be realized open easily, and the distance between press section 17 and rotating shaft 12 can design according to whole clamp, file can be made to use very laborsaving, comfortable.Meanwhile, the cross section of the other end of trepanning 14 and rotating shaft 12 is all set to polygon; Can prevent from, between trepanning 14 and rotating shaft 12, skidding occurs.

As the equivalent variations of the present embodiment, two sides of rotating part 6 are respectively equipped with the trepanning 14 matched with the other end of two rotating shafts 12, and the two ends of rotating part 6 are socketed (see accompanying drawing 6) with rotating shaft 12 respectively.

Embodiment 3:

As described in Fig. 7 to Figure 10, its structure difference from Example 1 of a kind of file is: described file also comprises the handle 8 for pressing, and the rear end face of described handle 8 is provided with the slot 10 matched with bent rod 4, and bent rod 4 inserts slot 10.

Handle 8 can be the handle 8 that matches with single bent rod 4, and when only having a rotating shaft 12 to be designed with bent rod 4, this handle 8 is enclosed within outside bent rod 4, due to this handle 8 comparatively bent rod 4 more easily control, convenient hand push pressure.Handle 8 also can for the handle 8 matched with two bent rods 4 simultaneously, when two rotating shafts 12 are all designed with bent rod 4, two bent rods 4 insert in two slots 10 of handle 8 front end face respectively, at this moment not only convenient hand push pressure, when pressing simultaneously, file is stressed also comparatively even, and the rotating shaft 12 at two places is also all subject to the effect of power.

Further, the middle part of the front end of described base plate 2 extends to form forward a lower clip arm 7.

After forming lower clip arm 7, conveniently can be fixed on backboard, hand also can be facilitated to clamp; When clamping, lower clip arm 7 and handle 8 form V-shaped, only need one hand just to nip lower clip arm 7 and handle 8, just can rotate by joystick 8 easily, and lower clip arm 7 and handle 8 are pinched as stress point and staff the hand-type pinched and coordinated, easy to use.In addition, because lower clip arm 7 protrudes from base plate 2, the middle part of lower clip arm 7 is provided with installing hole, can hang placement by installing hole file.

Further, the upper surface of described handle 8 is provided with convex body 9 for increasing frictional force or groove, and the present embodiment adopts convex body 9 structure.

When use hand is pinched and pinched, the active force of hand generally directly vertically can not act on the upper surface of handle 8, after arranging convex body 9 and groove, therefore can increase the frictional force of pressing; Prevent from skidding.

Further, the outer of described lower clip arm is arranged with upper overturning 15.

Arrange upper overturning 15, and the flange direction of upper overturning 15 is identical with the direction of the power acted on lower clip arm, makes lower clip arm when in use, the edge of lower clip arm can not scratch hand.

Further, the middle part of described lower clip arm raises up and forms reinforcement 16.

The middle part of lower clip arm raises up and forms reinforcement 16, makes lower clip arm can bear the power of increasing, lower clip arm can be prevented to be out of shape, increase the service life.

Further, the side of the rearward end of described handle 8 is provided with the hole clipping 18 for matching with the rotating shaft 12 of crotch 1.

After the slot 10 bent rod 4 of crotch 1 being inserted the rear end face of handle, the end of the rotating shaft 12 of crotch 1 is moved in hole clipping 18, thus the end of rotating shaft 12 is limited in hole clipping 18, handle 8 can be prevented when driving crotch 1 to rotate, and bent rod 4 moves along slot 10 opposite handle; Even bent rod 4 shifts out slot, makes troubles to use.In order to increase usability, the rear end of hole clipping 18 can be raised up, the end of the rotating shaft 12 of crotch 1 is limited in hole clipping 18 completely.

Below be only the preferred embodiment of the application, equivalent technical solutions on this basis still falls into application protection domain.
