Specific embodiment：

For the technical characterstic of this programme can be clearly described, below by specific embodiment, and combine its accompanying drawing, to this reality It is described in detail with new.

As Figure 1-3, a kind of reading assists book clamp, and including a clamping plate 1, before and after the front of clamping plate 1, both sides set respectively There is a leading screw 2, in the oppositely oriented external screw thread of leading screw 2 two ends setting, in the slide bar 3 that is respectively arranged on the left side and the right side of clamping plate 1, slide The two ends of bar 3 are sheathed on two leading screws 2 respectively, and the two ends bottom activity of slide bar 3 is placed in the cunning being arranged on both sides before and after clamping plate 1 On rail 4, two leading screws 2 pass through chain drive 5 and are connected, and are provided with swing handle 6 in one end of leading screw 2, activity respectively on two slide bars 3 Be provided with a slide 7, slide 7 active card be disposed along slide bar 3 length direction be extended chute 10 in, slide 7 is provided with One depression bar 8, one end of depression bar 8 is hinged with slide 7 with by being provided with the bearing pin of torsion spring, and the other end is abutted with the plate face of clamping plate 1.

It is provided with a U-type groove at the back side of clamping plate 1, hinged one U-shaped handss button bar 9 in U-type groove.

During use, books are launched to be put on clamping plate 1, then a leading screw 2 is rotated by swing handle 6, another leading screw 2 is in chain It is synchronized with the movement under the transmission of strip transmission mechanism 5, thus driving two slide bars 3 along slide rail 4 move toward one another, according to the big ditty of books Whole enter line slip slide 7 to after correct position, push down books using depression bar 8.When needing page turning, sliding slide 7 make depression bar 8 from Remove on books, reusing after page turning that depression bar 8 pushes down again can.When needs lie on a bed or stand reading, take for convenience Read additional lock, handss button bar 9 can be produced from U-type groove, people by handss stretch into handss button bar 9 hand-held reading additional lock read Read.

Above-mentioned specific embodiment cannot function as the restriction to this utility model protection domain, for the skill of the art For art personnel, any alternate modification that this utility model embodiment is made or conversion all fall within guarantor of the present utility model In the range of shield.

This utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
