Tutorial for making telescopic sword with building blocks

The tutorial of building block telescopic sword making is as follows:

1. Telescopic category: after the telescopic lattice pushes out the blade, the clamp clamps, the telescopic lattice retracts or the spring retracts. Up to now, most of them are controlled by multiple switches. Advantages: convenient use and simple principle. It is easy to make a multi-section cuff sword. Disadvantages: low reliability, difficult manufacturing and slow shrinkage. Design trend: single rope control switch, speed ejection and retraction.

2. Cuff sword is a very precise thing, and its principle is extremely complicated. However, there will be some simple and complicated designs to simplify the complex. After making 1: 1 with computer software sketch master, solidworks, 3D max or other drawing software, it is known through measurement. Use fine and simple processing materials, such as plastic board and wood board, to make concrete model for measurement. Pure technology is recorded after complicated calculation according to the reference object.

Accurate data is an extremely important part. After this link is prepared in advance, the cuff sword will perform perfectly at the beginning, which can leave energy and money time for your production. It plays an important role in optimizing the structure. It can realize expansion and contraction, solve the problem of expansion and contraction length well, and convert strength into length. The disadvantage is that it is laborious, and the structure will be a little strong if it is not done well.

4. The specific switch has a specific length, but the range of human fingers is limited, so your cuff sword will definitely be a laborious and distance-saving setting. Finger strength can not be ignored, and human functions complement each other. You need to get used to your fingers, and your finger strength will naturally go up.
