Description

Book clamp

The utility model is a kind of folder book stationery, and its function is that the steady page of folder is convenient to read-write.

At present, known folder book stationery is made up of panel, adjustable support and pressure angle.This book clamp folder book trouble, page turning inconvenience meet paper than the hard-book nationality, and page turns over easily and many defectives such as sticks up.

The purpose of this utility model provides a kind of book clamp, and it is easy not only to press from both sides book, and page turning is convenient, and is widely used in 32 and opens and the books of less format, even paper is stiff, folder book effect is also very desirable.

The purpose of this utility model is achieved in that there is shoulder in base plate bottom, and there is projection on last plane, and the base plate both sides are equipped with a clip that can advance or extract out respectively; Elongated wire is passed in the clip axle center, and steel wire is made the L type, and steel wire passes the screw of band radial hole, and screw cooperates with the base plate respective aperture and the knurled nut is housed; The support that can open or regain is housed below the base plate.During reading, extract double fastener out, book is put on the base plate, spine is opened page against left side projection, determines folder position, left side, screws the knurled nut, makes folder location, left side, at this moment, only can press from both sides steady page with the left side folder, and the right side folder needn't use; The book page turning increases, during the page perk of right side, can be again with the right side folder, and this moment, double fastener was also used; When the page turning of book increases when having only right side page perk, spine against base plate the right projection, is determined folder position, right side, screw the knurled nut, make folder location, right side, at this moment, only can press from both sides steady page with the right side folder, the left side folder needn't use.Open the support below the base plate, can change the reading visual angle.

Owing to adopt such scheme, make the folder book easy, page turning is convenient, even paper is stiff, page is launched well.

Below in conjunction with drawings and Examples, the utility model is further specified.

Fig. 1 is the utility model front perspective view.

Fig. 2 is the book clamp back view.

Fig. 3 is the A-A profile of Fig. 2.

Fig. 4 is a book clamp embodiment structural map.

Among the figure 1, base plate 2, left side folder 3, right side folder 4, knurled nut 5, screw 6, support.Wherein, the manufactured materials of base plate, left and right sides clamping plate is plastics, and the material of knurled nut, screw and support is common charcoal steel.

In Fig. 1, left side folder (2) and right side folder (3) are by the steel wire of elongation, pass in base plate (1) two side holes, wherein, steel wire one end passes radial hole (the steel wire head bending of screw (5), avoid during pull extracting out), screw (5) is gone up respective aperture with base plate (1) and is cooperated also spinning knurled nut (4), and support (6) is installed in below the base plate (1).

In the embodiment shown in fig. 4, folder (2) and right side folder (3) on the left of extracting out, spine is gone up two projectioies in the left side, plane against base plate (1), opens page, behind folder (2) position, screws knurled nut (4) on the left of determining, makes left side folder (2) location.At this moment, only can press from both sides steady page with left side folder (2), right side folder (3) needn't use.

Claims (3)

1, a kind of book clamp is characterized in that: in the base plate two side holes, penetrate the clip that can extract out, the steel wire that forms one with clip passes the screw radial hole, and screw cooperates with respective aperture on the base plate and the spinning knurled nut, and support is equipped with in the base plate bottom.

2, book clamp according to claim 1 is characterized in that there is shoulder in base plate bottom, and there is projection on last plane.

3, book clamp according to claim 1 is characterized in that the clip axle center passes steel wire and make the L type.
