In the Qing Dynasty, an old man sitting and watching wrote in "The Wild Notes of the Qing Dynasty": "The children's toys in the capital include the so-called empty bell, which is a bell from other provinces. It is made of bamboo tubes at both ends, with a column in the middle, and a rope is used to make the sound. . Only the empty bell from the capital (referring to Beijing) is round and flat in shape, with a shaft running through two wheels. Its sound is clearer and longer than those made in other provinces. "When shaking, the posture changes, making the rope tumble. Actions such as "crossing the bridge", "throwing each other", "circling", and "grabbing for heights" are also played using pot lids and other equipment instead of single-axis diabolo. There are many techniques for playing diabolo, including "immortal jump", "chicken on the shelf", "twirling", "flying all over the sky" and other names. Diabolo playing is a traditional acrobatic game activity among Chinese Han people. It is popular all over the country, especially in the north.

2 From the current structure, specifications, functions and raw materials of diabolo, its classification is as follows:

(1) According to the structure of diabolo, its types are as follows:

p>

1. Single-headed diabolo - one shaft is connected to a sounding wheel;

2. Double-headed diabolo - one sounding wheel is connected to each end of a shaft;

< p>3. Double-shaft diabolo - one shaft is connected to each side of the center of the sound wheel;

4. Louzi diabolo - whether it is single-head diabolo, double-head diabolo or double-shaft diabolo, Any connected multiple sounding wheels (more than 2) are diabolos for the building, such as: single-axis building (currently added to a maximum of nine floors); double-headed building (currently added to a maximum of 12 floors): double-axis building (Currently up to 3 levels).

5. Earth axis diabolo - a stick runs through the center of a sounding wheel, and is also equipped with a string and a bamboo board with holes.

(2) Divided by specifications: There are hundreds of sizes, the smallest diameter is only 2 cm, the largest can be more than 40 cm, but diabolo is often used (for practice or performance) Generally, 10 cm to 13 cm are used. Diabolo that is too small can be used to practice skills; diabolo that is too large can be used to practice arm strength, waist strength, and leg strength. (3) According to the raw materials, the types are as follows:

1. Bamboo-wood structure diabolo: It is made of thick bamboo poles cut and combined with wood. This is the most traditional method. Its advantages: the sound produced is pleasant to the ear, but its disadvantages: poor strength and easy to damage.

2. Plastic steel and plastic wood structure diabolo: Due to the development of modern science and technology, new materials are used, such as ABS engineering plastic injection molding, and then connected with metal shafts or wooden shafts. Its advantages: quality Basically the same: the service life is about 3 times that of bamboo-wood structure Ningzhu.

3. FRP (epoxy resin + glass fiber cloth) and wood structure diabolo:

The advantages: loud sound, high strength, good toughness, long service life, usually bamboo Wood structure diabolo 3 times to 5 times.

4. Plastic + metal structure diabolo: It is made of rubber or modified plastic and connected to a metal shaft. Its advantages: not easy to damage, longer service life, but silent (produced abroad), domestic Although the ones produced have sound, they are very small
