Appliance and connector for attaching same to machine

The utility model discloses an appliance and a connector for attaching the same to a machine. The connector comprises a mounting structure, a locking mechanism and a connection indicating assembly. Mounting holes are formed in the mounting structure and are configured in such a manner that mounting pins which are arranged on the appliance can be accommodated in the mounting holes. The locking mechanism comprises an actuating system which is rigidly connected to the mounting structure. The locking mechanism comprises a guide clamp disc, and the guide clamp disc is operationally connected to the actuating system and is configured in such a manner that the mounting pins accommodated in the mounting holes can be selectively locked by the guide clamp disc. The connection indicating assembly comprises a marking component which is pivotally connected to the guide clamp disc of the locking mechanism. An elastic component is attached to the marking component, so that the marking component can be offset and reaches a first position. The connection indicting assembly comprises a detection component, and the detection component is attached to the marking component and is configured in such a manner that the detection component and the mounting pins of the appliance can react to one another, so that the marking component can move to a second position. The appliance and the connector have the advantage that the complexity of an existing connection system can be lowered, operators do not need to manually detect and identify whether the appliance is forcedly locked with the connector or not, accordingly, the time can be saved, and the productivity of the machine can be improved.
