Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation Book word can be implemented according to this.

It should be noted that of the present utility model description in, term " horizontal ", " longitudinal ", " on ", D score, " front ", " afterwards ", the orientation of instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " or position relationship be based on Orientation shown in the drawings or position relationship, are for only for ease of description this utility model and simplify description, are not instruction or dark Show the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that right Restriction of the present utility model.

As shown in Figures 1 to 8, this utility model provides a kind of teaching to use textbook bracing frame, comprising:

Base 100, its bottom has a horizontal plane；

First expansion link 110, it is vertically arranged, the bottom of described first expansion link 110 and described base 100 Top is fixedly connected, and by adjusting the length of the first expansion link 110, supporting plate 130 can be made to have different height；

Gripper shoe 120, it is cuboid, and described gripper shoe 120 is horizontally disposed, the bottom of described gripper shoe 120 Portion is fixedly connected with the top of described first expansion link 110；

Supporting plate 130, it is cuboid, the length and width length with described gripper shoe 120 respectively of described supporting plate 130 Equal with width, described supporting plate 130 is arranged on the top of described gripper shoe 120, described supporting plate 130 side along its length Hinged with described gripper shoe 120 side along its length, that is, supporting plate 130 can rotate around gripper shoe 120, can adjusting supporting board 130 angle, thus adjusting the angle that teacher sees textbook, the top of described supporting plate 130 is divided along its width and length direction It is not arranged at intervals with multiple first grooves 131 and multiple second groove 132, the top of described first groove 131 is along described supporting plate 130 width is arranged at intervals with two pieces of first baffles 140, and described first baffle 140 is along the length of described first groove 131 Direction is arranged, and that is, along the bearing of trend setting of the first groove 131, the top of described second groove 132 is along described supporting plate 130 Length direction is arranged at intervals with two pieces of second baffles 150, and described second baffle 150 is along the length direction of described second groove 132 Setting, that is, along the bearing of trend setting of the second groove 132, described first baffle 140 and described second baffle 150 are rectangular The bodily form, two pieces of described first baffles 140 do not contact, and respectively with described first groove 131 relative to two sides fixing even Connect, two pieces of described second baffles 150 do not contact, and respectively with described second groove 132 relative to two sides be fixedly connected, Described first groove 131 is connected with described second groove 132, and described first groove 131 and described second groove 132 connectivity part First baffle 140 and second baffle 150 disconnect, described first groove 131 and described first baffle 140 are along described supporting plate 130 Width section respectively with described second groove 132 and described second baffle 150 along described supporting plate 130 length direction Section equivalently-sized, and each section be square；I.e. the width of the first groove 131 and the second groove 132 and depth are equal Identical, the width of first baffle 140 and second baffle 150 and height all same.First baffle 140 and second baffle 150 be for Restriction slide block 160 moves up to outside the first groove 131 and the second groove 132, also can fix slide block 160, make fixation clamp 180 Textbook can be clamped.

At least four slide blocks 160, it is optionally plugged in described first groove according to the width of textbook, length and thickness 131 and described second groove 132 in, described slide block 160 is the square bodily form, and the length of side of described slide block 160 is less than or equal to described The width of the first groove 131, the length of side of described slide block 160 is less than or equal to the bottom and described first of described first groove 131 Distance between the bottom of baffle plate 140, and the length of side of described slide block 160 is more than the distance between two pieces of described first baffles 140；So Slide block 160 can be made to insert in the first groove 131, and make slide block 160 be located at the lower section of first baffle 140, by first baffle 140 Limit slide block 160 to move upwards.

At least four connecting rods 170, it is equal with described slide block 160 quantity, and corresponds, and described connecting rod 170 is Cuboid, the bottom of described connecting rod 170 is hinged with the top of described slide block 160 or is rotatably coupled；So connecting rod 170 can rotate around slide block 160, so that fixation clamp 180 can rotate.

At least four fixation clamps 180, it is equal with described connecting rod 170 quantity, and corresponds, described fixation clamp 180 It is fixedly connected with described connecting rod 170, the top of described fixation clamp 180 is parallel with the top of described supporting plate 130, described fixation clamp 180 bottom tilts towards described connecting rod 170 gradually downward from the one end away from described connecting rod 170.For thicker book, On fixation clamp 180, the one end away from connecting rod 170 can be clamped, for relatively thin book, near connecting rod 170 on fixation clamp 180 One end can clamp, so that fixation clamp 180 can clamp the book of different-thickness.Fixation clamp 180 is arranged at least four, this Sample can clamp four angles of textbook completely, arranges four slide blocks 160, setting is more to be in order to preferably solid when actually used Determine textbook.

When using, the height according to teacher adjusts the length of the first expansion link 110 to this utility model, so that supporting plate 130 is had Have different height, by rotating pallet 130, make supporting plate 130 have different angles, further according to the width of textbook, length and Thickness sliding slider 160, enables fixation clamp 180 to clamp textbook.Taking only arrange four slide blocks 160 as a example, a fixation clamp 180 is right Answer an angle of textbook, textbook is placed on supporting plate 130, so that textbook is opened along the length direction of supporting plate 130, with textbook along supporting plate 130 length direction is length direction, and the width along supporting plate 130 is width, first by four slide blocks 160 about, front After be symmetrical arranged, when textbook is wider, four slide blocks 160 is slid in and out along the second groove 132 and can clamp class to fixation clamp 180 This four angles, when textbook is longer, four slide blocks 160 is slid in and out along the first groove 131 and can clamp class to fixation clamp 180 This four angles, when textbook is thicker, after opening textbook, the centre of textbook is thicker than both sides, by four slide blocks 160 along the second groove 132 slide in and out to fixation clamp 180 four angles that can clamp textbook, and as needed, also can further make four slide blocks 160 Slide in and out along the first groove 131 and can press textbook to fixation clamp 180.During fixing textbook, as needed by slide block 160 the Slide into fixation clamp 180 in one groove 131 and the second groove 132 and can clamp textbook.
