Tread surface, causes the damage of the components such as oil cylinder and oil pipe, while reducing setting bracket or the time of other supporting objects,
Accelerate the working efficiency of dismounting forearm, and ensure safety of forearm during inverting inversion, eliminates due to supporter
Security risk caused by unreliable.
2) by setting hole for hoist, the time of setting assembly suspension hook hook can be reduced, makes to lift during lifting
It is more convenient, the working efficiency of lifting is improved, while avoiding forearm and the unmatched situation of hanging device.
3) by setting height adjusting part, suitable height can be adjusted when forearm is inverted in reversion, to solve
Practical reversion is inverted the problem of being caused in forearm due to difference in height, while suitable height can be adjusted according to practical situation.
4) by setting shock absorber part, vibration caused by placing and vibration can be reduced during forearm is inverted in reversion
Damage to forearm, while ensuring that forearm is steady when inverting inversion.

Specific embodiment
To keep the technical solution of the utility model and advantage clearer, below in conjunction with specific embodiment and specification
Attached drawing is described in further detail the utility model and its advantages, but the embodiments of the present invention is not limited to
This.
As shown in figures 1-4, a kind of small arm of digger, including small arm body, small arm body one end are equipped with scraper bowl mounting portion 1,
The small arm body other end is equipped with large arm mounting portion 2, and forearm bodies top is equipped with upper ear plate 3, and forearm bodies top is additionally provided with anti-
Protection unit, protective device 4 can be mounted on forearm bodies top by the modes such as being spirally connected, being clamped, can also be with small arm body one
It is body formed.When small arm body is inverted and is inverted, protective device is damaged for preventing forearm bodies top components touching ground,
