Application: It can simplify the transmission machines, at the same time the transmission accuracy is high and widely used. It is mainly used for computer cases, control cabinets, furniture, electrical appliances and other tight spaces where screwdrivers cannot work properly. Strong and stable: Metal material, sturdy and durable, with good durability and long service life. Standardized manufacturing can ensure machine accuracy to achieve a high degree of compatibility with devices. Stiffness is small: Elasticity can be bent freely. It is used to connect two different waves in the same direction or have the relative motion to transfer movements. It can flexibly transfer the rotation movement in any position. Applicability: The flexible shaft can be used for general cordless screwdrivers and also for electric screwdrivers. The flexible shaft head can be installed with a hexagonal handle screwdriver bit (1/4 handle), a hexagonal screwdriver or a cordless screw drill rod with a diameter of 6.35 mm (1/4 inch). Flexible: The metal tube is bent 300 degrees, can be rotated in different directions and is easy to control. Flexible drill extension solves the problem of car engine frame disassembly screw repair. Reach dead corners and tight parts, outperform conventional screwdrivers
