The level height for filling section is lower than the level height of left construction section, and the linkage section is obliquely installed to right front from left to right, described
The tilt angle of linkage section upper surface with respect to the horizontal plane is greater than the tilt angle of lower surface with respect to the horizontal plane；The left installation
Section tilts down setting from left to right, and the left construction section upper and lower surface is in the cambered surface of indent.
The upper and lower surface of the right construction section and linkage section is equipped with reinforcing rib along its edge respectively.
The thickness of the right construction section is greater than the thickness of linkage section right end.
The right mounting hole small big taper hole under being.
Linkage section equivalent width in the front-back direction.
The left construction section corresponds to the first left mounting hole and the end of the second left mounting hole is respectively equipped with boss, and boss is corresponding
The end of first left mounting hole and the second left mounting hole is respectively equipped in pyramidal limiting slot, and the internal diameter of the limiting slot is by interior
Be gradually increased outward, the minimum diameter of the limiting slot respectively with the internal diameter of corresponding first left mounting hole and the second left mounting hole
Unanimously.
After adopting the above structure, the utility model passes through the improvement of left and right construction section, linkage section, makes arm body angle, size
Bonding strength at variation is more preferable, and stress, which is concentrated, to be reduced, and effectively improves arm body intensity, improves the service life and safety of arm body
Property.
Detailed description of the invention
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model:
Fig. 1 is the structural schematic diagram of the utility model；
