323 and second slideway 315, it is thus connected device 3 and comes off from wear-resistant components, tear tooth process open and complete.
During excavating equipment work, digging force acts on wear-resisting tip 2, and chamber portion 21 is passed through to excavating equipment in wear-resisting tip 2
Conducting, the pin-and-hole of the most wear-resisting root 1 and the through hole of wear-resisting tip 2 are in concentric or that inner circle is tangent state, by
Radial dimension in adapter 3 is less than pin-and-hole, clear size of opening, so adapter 3 is in free state in pin-and-hole, through hole.When
Adapter 3 also can be produced from side and clash into by right irregular building stones, but the shock dynamics of non-frontal is limited, bearing pin main body
312 have strong restriction effect with jump ring 33 to the boss 113 of wear-resisting root 1, and the side impact of building stones also cannot make adapter 3
Escape wear-resistant components, it is ensured that the safety that adapter 3 uses.Alternatively, adapter can have elasticity, now its radial ruler
Very little can also be more than pin-and-hole, the size of through hole.
When adapter 3 uses, muddy water can enter, and by accumulation for a long time, muddy water can become hard, market much connects
The inefficacy connecing device 3 is all such reason, and this utility model has taken into full account this situation, by controlling wear-resisting root 1 pin-and-hole
The building stones preventing bulk with the size of adapter 3 enter.Owing to accommodating district 324 for a long time by shared by the boss 113 of wear-resisting root 1
Neck, then the region that the intrusion of muddy water can exist is the second slideway 315 and the first slideway 323.During installation, each parts are totally without examining
Consider muddy water;After using after a while, when wear-resisting tip 2 is removed, although hard clod occupies the second slideway 315 and the
One slideway 323, but in demolishing process, the another one effect of the boss 113 of wear-resisting root 1 highlights again, that is, shear
Clod, touches adapter 3 in the X-axis direction at the second through hole 212 of wear-resisting tip 2, and now boss 113 will have one to clod
Individual shear action, clod flows out along the second slideway 315 and the first slideway 323, adapter 3 and pin-and-hole, the size difference of through hole
To mediate these the most size-reduced clods, demolishing process terminates.
