Fig. 1 is a schematic structural diagram of a conventional pin.
Referring to fig. 1, the excavator body includes a pin 10, one end of the pin is radially provided with a first connecting through hole 11, the accessory includes a sleeve, and the sleeve is provided with a second connecting through hole. When the accessory is replaced, the bolt sequentially penetrates through the second connecting through hole in the sleeve and the first connecting through hole 11 in the pin shaft 10, and then the bolt is screwed and fixed through the nut, so that the accessory is replaced.
However, at the time of actual replacement of the attachment, since the first coupling through-hole 11 of the pin shaft 10 on the excavator body and the second coupling through-hole on the sleeve are not necessarily aligned, the bolt cannot smoothly pass through. Currently, the following two methods are adopted for adjustment:
the first adjustment mode is as follows: the pin shaft of the excavator body is radially provided with an adjusting hole, and during specific adjustment, the pin shaft is driven to rotate along the axis of the pin shaft through inserting a tool into the adjusting hole. When the first adjusting mode is adopted for adjustment, the aperture of the adjusting hole needs to be large enough, and if the aperture is too small, the pin shaft 10 cannot be rotated after the tool is inserted. When the aperture is large, the length of the pin 10 needs to be increased.
The second adjustment mode is as follows: the pin shaft 10 is driven to rotate along the axis of the pin shaft 10 by means of the plane on the fixing plate 12 at the end part of the pin shaft 10 and pulling at the plane through a large wrench. When a large-scale wrench is matched with the plane of the fixing plate 12 for pulling, a large-scale wrench is needed under general conditions, and due to the fact that the large-scale wrench is used less times, a suitable large-scale wrench is not easy to find out during specific replacement, and smooth adjustment is not facilitated.
