Problems solved by technology
[0002] In the existing electric wrench, the motor directly drives the flywheel to rotate, and it will inevitably stop instantly under the reaction of the impact. If the torque of the motor is small, the nut cannot be removed, so the motor is required to have enough power, so the size of the electric wrench is usually large. , it is inconvenient to use, the flywheel rotates at high speed, there is no protection device, it is very dangerous

The invention discloses an improved electric wrench comprising a motor and a flywheel. The motor is connected with an output shaft through a belt. The end of a motor shaft is connected with a small gear engaged with a buffer gear. The buffer gear is connected with the flywheel provided with a torque regulator. The fly wheel is mounted on an output shaft, and the tail end of the output shaft is connected with a rotary shaft and is sleeved with a nut sleeve. A safety cover is sleeved on the flywheel. A buffer spring and a buffer pad are arranged between the buffer gear and the flywheel. Two sides of the flywheel are provided with centrifugal blocks provided with return springs. The improved electric wrench has the advantages that the buffer gear, the buffer spring and the buffer pad are arranged between the motor and the flywheel, the centrifugal blocks move under the centrifugal effect of the flywheel to engage with the output shaft, the output shaft rotates and drives the nut sleeve to produce sufficient impacting force to a nut and open the nut.
Description
technical field [0001] The invention relates to an electric wrench, in particular to an improved electric wrench. Background technique [0002] In the existing electric wrench, the motor directly drives the flywheel to rotate, and it will inevitably stop instantly under the reaction of the impact. If the torque of the motor is small, the nut cannot be removed, so the motor is required to have sufficient power, so the size of the electric wrench is usually large. , It is inconvenient to use, the flywheel rotates at a high speed, there is no protective device, it is very dangerous. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide an improved electric wrench with easy-open nut and small volume. [0004] The technical scheme adopted in the present invention is: [0005] The improved electric wrench includes a motor and a flywheel, the motor is con...
