Connect problem.
For achieving the above object, this utility model adopts the following technical scheme that：
A kind of attachment structure with eccentric pin shaft, including quick connector, excavator accessory and eccentric pin shaft, described digs
Pick machine accessory is connected with described quick connector by described eccentric pin shaft, and described eccentric pin shaft includes two bearing pin heads and with two
The pin body that individual bearing pin head connects as one, described bearing pin head and described pin body are provided in round structure, described in two
Bearing pin head concentric, the center of circle of described bearing pin head is deviateed in the center of circle of described pin body.
As a kind of improvement of the present utility model, the center of circle of described pin body and the center of circle of described bearing pin head are apart from H
For 10 ~ 30mm.
As a kind of improvement of the present utility model, the center of circle of described pin body and the center of circle of described bearing pin head are apart from H
For 15mm.
As a kind of improvement of the present utility model, one of two described bearing pin heads are provided with fixing hole.
As a kind of improvement of the present utility model, described quick connector has two and connects hook, described excavator accessory
There are two groups of connecting holes side by side, two described eccentric pin shafts are arranged on two groups of connecting holes side by side, two described connections hook
It is connected in two described eccentric pin shafts respectively.
As a kind of improvement of the present utility model, described excavator accessory is bucket, quartering hammer, bucket hook and grab bucket.
The beneficial effects of the utility model are：This utility model includes quick connector, excavator accessory and cam pin
Axle, described excavator accessory is connected with described quick connector by described eccentric pin shaft, and described eccentric pin shaft includes two pins
Spindle nose and the pin body connecting as one with two bearing pin heads, described bearing pin head and described pin body are provided in round tying
Structure, two described bearing pin head concentrics, the center of circle of described bearing pin head is deviateed in the center of circle of described pin body.Due to this utility model
Bearing pin be eccentric pin shaft, when it is connected with excavator accessory adjustable orifice away from（Reduce pitch-row or increase pitch-row）, so solve
Determine the connectivity problem of quick change adapter connector and excavator accessory.

Specific embodiment
With reference to specific embodiment and Figure of description, this utility model is described in further detail, but this
The embodiment not limited to this of utility model.
As shown in Fig. 1 ~ 5, a kind of attachment structure with eccentric pin shaft, including quick connector 1, excavator accessory 2 and
Eccentric pin shaft 3, excavator accessory 2 is connected with quick connector 1 by eccentric pin shaft 3, and eccentric pin shaft 3 includes two bearing pin heads 31
And the pin body 32 connecting as one with two bearing pin heads 31, bearing pin head 31 and pin body 32 be provided in round structure, and two
Individual bearing pin head 31 concentric, the center of circle of bearing pin head 31 is deviateed in the center of circle of pin body 32.Usually, the center of circle of pin body 32 with
The center of circle of bearing pin head 31 apart from H be 10 ~ 30mm, excavator accessory 2 have two installation pin body 32 hole, they
Pitch-row is typically in the range of this.The center of circle of pin body 32 is arranged apart from H by present embodiment with the center of circle of bearing pin head 31
For 15mm.
Preferably, one of two bearing pin heads 31 are provided with fixing hole 311, and this fixing hole 311 is used for adjustment hole away from rear
Fixing eccentric pin shaft 3.
Preferably, quick connector 1 has two connection hooks 11, and excavator accessory 2 has two groups of connecting holes 21 side by side,
Two eccentric pin shafts 3 are arranged on two groups of connecting holes 21 side by side, and two connect hook 11 and are connected in two eccentric pin shafts 3 respectively.
