1. Prepare manufacturing materials and tools: wooden boards, electric drills, saws, tape measures, loose-leaf hinges, nylon ropes, right angles, hammers and nails. 2. The cut wooden board is positioned with the aid of a right-angle device, hammered into a right-angle arch bracket with nails, and inserted into the beam plate at the middle height of the two legs of the bracket. 3. Make four wooden shelves, tighten the screws and connect the shelf brackets with loose leaves. 4. Drill holes in the middle of the beam and slab, and tie both ends of the rope head after passing through the nylon rope.

5. A pair of shelf table brackets can be folded in half when not in use. When in use, a simple folding table is formed by opening a board on them.

Exercise 2

1. First make a small shelf at the back, and fix the shelf with wood gluing screws. 2. Then make the desktop and legs on both sides, and pay attention to the hollowing out and cutting style of the legs. 3. Fix the table legs and shelf side plates with long hinges, and test whether they can freely expand and contract. 4. Finally, link the desktop with the shelf beam with a long hinge (the reason why the side hinge is installed first and then the desktop is installed is to let the desktop wrap its legs).

Characteristics of folding table

Various materials: the common materials of folding computer desk are wood-based panel, solid wood, aluminum-magnesium alloy, ABS material, bamboo and so on. Generally, wood-based panels are the mainstay, and colorful patterns can be attached to the decorative surface, which has a wide range of choices and reasonable prices; Aluminum-magnesium alloy computer desk is relatively high-grade. Through scientific design and simple appearance, it can be used for a long time.

Heat dissipation: Generally, the folding computer desk will be designed under the board to prevent the computer from overheating due to long-term use. Folding: The biggest feature of this computer desk is its small size, simple structure and portability. When in use, the legs of the computer desk can be completely placed under the desktop, which does not occupy too much space, is beneficial to storage, does not need to be disassembled, and is convenient to use.

Adjustment: Some folding computer desks with slightly complicated structures can be adjusted from multiple angles to meet the needs of different angles, so as to achieve the best and most comfortable posture. Non-slip: Some computer desks are equipped with baffles at the edge of the desktop to facilitate computers, books, etc. It will not slide down when adjusting the desktop angle.
