Hereinbefore, boss 113 is formed in pin-and-hole, and alternatively, boss 113 can also be formed in through hole.

During installation:

1) first, see Fig. 9 and Figure 11, wear-resisting tip 2 can be installed, by resistance to after wear-resisting root 1 is fixed on bucket labial lamina The chamber portion 21 in sharpening portion 2 is enclosed within the department of assembly 11 of wear-resisting root 1, chamber portion 21 and department of assembly 11 just phase contract, now, and wear-resisting The pin-and-hole in portion 1 and the hole of wear-resisting tip 2 are in the concentric or tangent state of inner circle of approximation, and the first through hole 211 of wear-resisting tip 2 is with resistance to First pin-and-hole 111 of mill root 1 is corresponding, and the second through hole 212 of wear-resisting tip 2 is relative with the second pin-and-hole 112 of wear-resisting root 1 Should；Being inserted into by adapter 3 in the pin-and-hole of wear-resisting root 1 and the through hole of wear-resisting tip 2, bearing pin main body 312 is by wear-resisting tip 2 The first through hole 211 enter the first pin-and-hole 111 of wear-resisting root 1, be persistently inwardly inserted into, until making the boss of wear-resisting root 1 113 by the second slideway 315 on the bearing pin head 311 of adapter 3, and now, boss 113 enters in the first slideway 323, Due to the barrier effect of jump ring main body 331 of jump ring 33 in X-direction, adapter 3 cannot continue deeper into shifting in the X-axis direction Dynamic；

2) then, see Figure 10 and Figure 12, the dismounting clamping part 313 that toothed tool 4 inserts or put on adapter 3 will be torn open, Rotary connector 3 certain angle, now boss 113 applies pressure to jump ring 33, and cushion 32 makes jump ring 33 in the Y-axis direction Produce certain elastic module so that boss 113 is in the rotation process of adapter 3, it is possible to convex by the stop on adapter 3 Playing 332, until boss 113 enters in the receiving district 324 of adapter 3, the end of bearing pin main body 312 is then through wear-resisting root Second pin-and-hole 112 of 1 enters the second through hole 212 of wear-resisting tip 2；Then, due to the elastic-restoring force of cushion 32, cushion 32 resiliences, stop that protruding 332 can stop the activity of boss 113 (boss 113 can be stoped to return to first in the Y-axis direction In slideway 323), and the second end end wall 3142 of the groove 314 of bearing pin head 311 and jump ring 33 are to boss 113 in the X-axis direction There is restrictive function.Thus, adapter 3 all cannot be movable in X-axis and Y direction, and wear-resistant components is in steady statue, by means of Tearing toothed tool 4 open, this installation process becomes very comfortable.

After use after a while, wear and tear in wear-resisting tip 2, when needing to change, uses and tears toothed tool 4 rotary connector open 3, direction of rotation is contrary with when installing, and can be labeled with clear and definite rotation instruction on adapter 3, so that wear-resisting root 1 Boss 113 invert the receiving district 324 from adapter 3 and return to the first slideway 323, then from the second through hole 212 of wear-resisting tip 2 Adapter 3 (applying active force on the axial direction of bearing pin 31) is touched at place, and boss 113 is taken advantage of a situation the first slideway by adapter 3 323 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.
