Drill chuck is the main parts of small drill type electric tool, electric drill costsaccounted for 10%-15%. Common are key drill chuck, at present, development and production of light closefisted drill chuck has achieved remarkable results.Hand, self tightening drill chuck, there is an important index, is the output torqueof drill chuck can be greater than the input torque is more than 90%. The high-end drill chuck is mainly used in the requirements of the higher professional power tools, drill and other occasions, the high performance self-locking drill chuck and heavy spanner drill chuck increased demand. High performance self-locking drill chuck has the advantages of high precision, high technology content,high added value and high efficiency and so on, DC electric impact drillsupporting electric impact drill and 24V 850W more than a small desk major and professional class of electric tools. Chuck shell are engineering plasticsmanufacturing, light weight, and is favorable for environmental protection; there are also metal chuck, high strength, good rigidity; chuck coaxial degree is very high, can ensure machining accuracy; chucks top with six hexagon head, very easy to chuck installation, fastening and disassembly; chuck top with rotary dust cover, with work to prevent dust, debris embedded chuck and the operator can be used to support the dual role of the drill chuck to make work more stable; the clamping claw by special hardening, high strength, drilling force is too large when the drill rotates in the clamping jaws, but can not be damaged chuck jawswith clamping force signal function. In the clamping bit or working, when the clamping force reaches a certain value clip hair out "clicking" sound, tell the userbit has been completely clamping, tool can be absolutely safe to use. With theclamping force, the drill bit can be issued three times a "clicking" sound,respectively corresponding to the clamping force of the three kinds of different sizes, small bench drill can be either in the three clamping force in stateabsolutely safe to use. The clamping force signal can make the drill chuckclamping force and security work in the best condition, and can greatly prolong the service life of chuck. And the clamping force signal can give the user a verygood feeling, making it extremely easy to judge whether to achieve the bestchuck clamping force and safe state, thereby avoiding the clamping force is not enough, the big force of drill bit slippage damage accident and clamping.
