Abstract

The invention discloses a handheld electric tool noise and vibration reducing device which comprises a handheld electric tool clamping transmission portion and a motor output portion. The motor outputportion is in driving connection with the handheld electric tool clamping transmission portion through the noise and vibration reducing device. By the adoption of the noise ad vibration reducing device, vibration brought when large-diameter clamps and different shafts are clamped can be effectively reduced, and noise brought when different shafts work can also be effectively reduced. The servicelife of the machine can be effectively prolonged, and the device has the performance of isolating vibration.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a noise reduction and vibration reduction device for a hand-held electric tool. Background technique [0002] In existing electric tools, such as brushless jade engraving machines, etc., the link between the front clamping part and the rear motor part is usually a hard link. Its disadvantages are: 1. The clamps (engraving tools, grinding tools, and steel sand clamps) in the front clamping part during work, especially the vibration caused by large-diameter tools will be transmitted to the motor part, causing damage to the motor part; 2. The noise caused by the vibration is large. Contents of the invention [0003] The object of the present invention is to provide a noise reduction and vibration reduction device for a hand-held electric tool to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invent...
