Preference, in order to ensure that beat is reliable and stable, described swing arm side is provided with the hinged otic placode for installing oscillating oil cylinder, described hinged otic placode and oscillating oil cylinder be articulated with A point, swing arm and swing save be articulated with B point, swing save with oscillating oil cylinder be articulated with C point, the line of described three pin joints constitutes linkage, and pin joint C is that radius rotates with BC under the driving of oscillating oil cylinder.Piston rod excacation device when meta of described oscillating oil cylinder is also at meta, and the flexible promotion of oscillating oil cylinder swings joint beat, and its deflection angle controls at 50 to 60 degree.

Preference, stretch to extreme position to prevent oscillating oil cylinder and avoid oscillating oil cylinder and swing arm to interfere, described swing arm is provided with limited block, when described swing joint swings its medial surface contact with limited block realize spacing.

Preference, in order to expand job area, described dipper comprises flexible interior dipper and telescopic oil cylinder, and described flexible interior dipper is arranged on dipper inside, and dipper can slide along bucket arm length direction in flexible, described telescopic oil cylinder two ends are hinged with flexible interior dipper with dipper respectively.

Beneficial effect: the utility model is simple and reliable for structure, low cost of manufacture; The quality of foundation or at the foot of the hill operation under special operation condition and efficiency are significantly improved; The setting of extensible bucket rod is entered one and is not improve operating efficiency and job area.
