The machine is made up of motor, flexible axle subassembly, vibrating bar 1, The husk of motor is made by aluminum alloy, the upper is installed with switchand handle bar, the top is equipped with hold-back device and joint ends, whichmakes it move easily and flexibly. 2, The hold-back device is born by a pushing key. When motor rotates in forward directionaccording to the requirement, due to the centrifugal force, the end ofpushing key quickly plugs in flexible axle pin, push flexible axle rotate, and causebar to vibrate. When motor rotate in reverse because of the correct up-downconnection of electrical wire, the pushing key comes away with the plug of flexibleaxle, thus prevents the reversal plunge into and gets the purpose of protectingflexible axles. 3, The motor adopts the newest three-phase asynchronous motor that has characteristicsof small volume, lightness, full seal, grade E insulation and can be usedin places full of dust and splashing water and soils producing area:China payment:TT supplying capacity:50pcs/month
