Problems solved by technology

[0002] In order to make the blade of the electric tool similar to the green pole machine stop quickly when the power tool is stopped, the previous torsion spring clutch brake structure is to fit the torsion spring in the hole of the large gear and the eccentric block seat by interference, and through the reverse direction of the torsion spring Tension force transmission, when braking, tighten one end of the torsion spring through the cage to make the blade and the motor clutch. The disadvantage is that the precision of the parts is high, and it is easy to cause slippage when transmitting a large torque.

Abstract

The present invention discloses a brake device and electric tool containing said brake device. Said brake device includes the following several portions: large gear which is driven by a drive device; eccentric block which is driven by large gear through the agency of a clutch device, said eccentric block can be used for driving tool blade and making it work, the described clutch device includes a brake disk positioned over said large gear, the eccentric block is positioned under the large gear, and coaxially-connected and fixed with said brake disk, and a pair of shifting forks is pin-connected on the brake disk. Besides, said invention also provides the concrete working principle of said brake device and its concrete operation method.

Description

technical field [0001] The invention relates to a brake device and an electric tool containing the brake device. Background technique [0002] In order to make the blade of the electric tool similar to the green pole machine stop quickly when the power tool is stopped, the previous torsion spring clutch brake structure is to fit the torsion spring in the hole of the large gear and the eccentric block seat by interference, and through the reverse direction of the torsion spring Tension force transmission, when braking, tighten one end of the torsion spring through the cage to make the blade and the motor clutch. The disadvantage is that the precision of the parts is high, and it is easy to cause slippage when transmitting a large torque. Contents of the invention [0003] The object of the present invention is to provide a brake device and an electric tool containing the brake device, which can disengage the blade from the driving device and stop immediately when the device...
