Tightly, opening oil cylinder 14 and c-type card 16 is more closely adhered to the side wall of mounting hole 13, open oil cylinder 14 and c-type card at this time
Spacing between 16 slightly becomes larger, and wedge 15 can be further inserted into therebetween, is closely attached toothholder retaining mechanism 12
In mounting hole 13, finally so that toothholder 11 is closely installed in the lip of bucket.
Toothholder 11, can very easily be connected in lip by the mounting means of this structure in assembling.And make
Toothholder 11 is securely attached in lip.
As can be seen from figures 8 and 9, c-type card 16 is away from the one side for opening oil cylinder 14 structure low between the senior middle school of both ends so that C
Buckling groove 18 is formed on type card 16;It is respectively provided with stop part 21 on first root 19 and the second root 20, buckling groove 18 is by stop part
21 are connected in inside buckling groove 18.
When connecting toothholder retaining mechanism 12, first c-type card 16 is inserted into mounting hole 13, makes the first root 19 and second
The stop part 21 in portion 20 is located in buckling groove 18, c-type card 16 is vertically being rocked;Oil cylinder 14 and wedge will be opened afterwards
15 install into mounting hole 13, and oiling causes toothholder retaining mechanism 12 closely to connect.
As shown in Fig. 4 and Fig. 7, c-type card 16 has the first tooth engaged 22 close to the one side of wedge 15, and wedge 15 is close to c-type
The one side of card 16 has the second tooth engaged 23, and the first tooth engaged 22 is engaged with 23 phase of the second tooth engaged.
To opening in oil cylinder 14 after oiling, tapping wedge 15 makes its downlink, makes the first tooth engaged 22 and the second tooth engaged
23 occlusal positions are lower, and wedge 15 can not uplink after making two groups of tooth engaged occlusions.
As shown in the figure, first tooth engaged 22 has the first inclined-plane and the second inclined-plane, the first inclined-plane and c-type card on c-type card 16
For angle between 16 length directions less than 45 degree, the angle between 16 length direction of the second inclined-plane and c-type card is more than 45 degree, passes through
Such setting so that wedge 15 can not uplink after the first tooth engaged 22 and the occlusion of the second tooth engaged 23.
As shown in Figures 5 and 6, opening oil cylinder 14 includes cylinder body 24, and the top of cylinder body 24 is provided with cylinder cap 25, cylinder cap 25 and
Cylinder body 24 is detachably connected, and the pump nozzle 26 connected inside cylinder body 24 is provided between cylinder cap 25 and cylinder body 24.
Shown with cylinder cap 25 in Fig. 4.Cylinder cap 25 is set outside pump nozzle 26, cylinder cap 25 is played protection to pump nozzle 26
Effect, enables pump nozzle 26 in the excavator course of work to be protected.
The sidepiece of cylinder body 24 has extension 27, and the middle part of extension 27 forms vertical mounting groove 28;In mounting groove 28
Screw rod 29 is hinged with, screw rod 29 can be rotated around horizontal axis;The top ends of screw rod 29 are bolted with nut 30;Have on cylinder cap 25
