Detailed Description

The utility model is further described with reference to the following figures and specific embodiments.

Example (b):

referring to fig. 1, the hand-push type brush cutter of the present embodiment includes a frame assembly 4, a handle, an engine 9 and wheels 3 mounted on the frame assembly 4, a cutting rod 6, and a grass-mowing head 5 mounted at the front end of the cutting rod 6, wherein a transmission shaft is disposed in the cutting rod 6, and two ends of the transmission shaft are respectively connected to a power output end of the engine 9 and a power input end of the grass-mowing head 5. The part of the cutting rod 6 connected with the power output end of the engine 9 is sleeved with a vibration damping rubber pad 8, a pressure plate 7 is assembled outside the vibration damping rubber pad 8, and the pressure plate 7 is fastened at the front end of the frame assembly 4 through bolts. The wheels 3 are used for walking and supporting the main body of the whole brush cutter.

The handle comprises a middle handle 2 and an upper handle 1, the middle handle 2 is of a U-shaped structure, and two end parts of the middle handle are butted and fixed on two ends of the tail part of the frame assembly 4; the upper handle 1 is also of a U-shaped structure, and two arms of the upper handle are positioned outside two arms of the middle handle 2 and are fixedly connected with the two arms of the middle handle 2 through bolts; the upper handle 1 is provided with a throttle mechanism 12 on the arm for controlling the operation of the engine.

The engine 9 is a 1E48F type gasoline engine, and the bottom of the engine is fixed on an engine base 13 of the frame assembly 4; and a support plate 11 is fixed at the tail part of the frame assembly 4. Two groups of damping devices are arranged between the engine base 13 and the supporting plate 11, each damping device comprises a middle damping rubber column 10 and bolts fixed at two ends of each damping rubber column 10, and the bolts at two ends of each damping rubber column 10 are respectively connected with the engine base 13 and the supporting plate 11.
