Problems solved by technology

[0002] The venetian blind is a kind of supporting equipment for blocking sunlight, sight, etc. It is used more in the company's office. The venetian blind is mainly made of aluminum alloy and wood and bamboo baking varnish. It is durable and always new, easy to clean, not aging, Non-fading, sunshade, heat insulation, breathable and fireproof, etc., can be controlled automatically or manually. Now there are magnetic control built-in louver glass and electric built-in louver glass on the market. At present, the magnetic control louver glass is easy to demagnetize and cannot be controlled. The electric venetian blind motor is built-in and easy to break, and the maintenance cost is high. With the continuous development of technology, people have higher and higher requirements for the manufacturing process of venetian blinds.
[0003] In the prior art, the patent with the authorized announcement number CN201920052132.7 discloses a double-control hollow glass built-in blind that can prevent the blind from slipping down. Between the control mechanisms, there will be no abnormal downward movement of the venetian blind due to the abnormal upward displacement of the control mechanism in the venetian blind lifting traction rope. The existing venetian blinds have certain disadvantages in use. First, when using When it is used, the control is more troublesome, the effect of the transmission drive is poor, and the stretching failure may occur due to its weight, which is not conducive to people's use. In addition, the biggest difference between the magnetic control louvers currently used on the market is that they will not be affected by Due to the weakening of the magnetic force caused by high temperature and time and other factors, the blinds cannot be controlled, which has brought certain adverse effects on people's use. Therefore, we propose a pull-bead blind
