Preferably, a stabilizing plate is fixed at the bottom of the supporting leg.

Preferably, a storage box is fixed to the lower surface of the table plate.

Preferably, one end of the clamping rod contacting with the table plate is semicircular.

Preferably, the upper surface of the supporting plate is provided with a limiting plate.

The invention has the beneficial effects that:

1. the supporting plate has the advantages that the supporting plate is lifted to a proper angle by overturning one end of the supporting plate inside the groove during reading, the supporting rod is overturned to the bottom of the supporting plate, the supporting plate is pressed downwards to enable the supporting rod to be connected with the limiting groove below the supporting plate in a clamped mode, the supporting plate angle is fixed, the angle can be adjusted automatically according to the height and the habit of a reader, both hands are liberated, and convenience is brought to the reader when the reader needs to read multiple books for comparison.

2. The clamping devices are arranged on two sides of the supporting plate, the clamping rods are pressed at one ends, the other ends of the clamping rods pull the pressure springs to lift the clamping rods, the bottoms of the clamping rods are respectively placed at two ends of a book, the clamping rods are placed down to fix the book, and the clamping rods are semicircular and small in contact area, so that pages can be directly inserted into the bottoms of the clamping rods when the pages are turned, the clamping rods do not need to be pressed when the pages are turned, and the reading comfort and the reading quality are improved.

In the figure: 1. a stabilizing plate; 2. a support leg; 3. a table plate; 4. a groove; 5. a storage box; 6. a support plate; 7. a limiting plate; 8. a support bar; 9. a limiting groove; 10. a clamping device; 11. a clamping lever; 12. fixing the rod; 13. a pressure spring.

Detailed Description

Any feature disclosed in this specification may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

As shown in fig. 1-5, the portable desk for the library comprises supporting legs 2, a desk plate 3, a supporting plate 6, a supporting rod 8 and a clamping device 10, wherein the supporting legs 2 are fixedly connected to four corners of the bottom of the desk plate 3, a groove 4 is formed in the top of the desk plate 3, the supporting plate 6 is rotatably connected to one side of the inner wall of the groove 4 through a hinge, limiting grooves 9 are formed in the bottom of the supporting plate 6 at equal intervals, the supporting rod 8 is rotatably connected to one side, far away from the supporting plate 6, in the groove 4 through a hinge, the supporting rod 8 is clamped in the limiting grooves 9, the clamping device 10 is symmetrically arranged on the upper surface of the supporting plate 6, the clamping device 10 comprises a fixing rod 12, a pressure spring 13 and a clamping rod 11, one end of the fixing rod 12 is fixedly connected to the upper surface of the desk plate 3, one end, the clamping rod 11 is fixedly connected with a pressure spring 13, and one end, far away from the clamping rod 11, of the pressure spring 13 is fixedly connected with the upper surface of the table plate 3.

The bottom of the supporting leg 2 is fixed with a stabilizing plate 1, so that the contact area between the desk and the ground is increased, and the stability is improved.

The lower surface position of the table plate 3 is fixed with a storage box 5 which can be used for placing personal articles.

The one end that presss from both sides tight pole 11 and table 3 contact is the semicircle, reduces the area of contact with table 2, reduces frictional force, is convenient for place the page clamping rod 11 bottom.

The limiting plate 7 is arranged on the upper surface of the supporting plate 6 and used for limiting the position of books and improving the reading quality.
