1. A knuckle arm adapted to be connected to a machine body and a top cover of a machine, said knuckle arm comprising:
- a mounting seat including a mounting block adapted to be disposed fixedly on the machine body, and a first pivot block extending integrally from said mounting block and having a first cam edge;
a connecting seat connected pivotally to said first pivot block of said mounting seat and adapted to be attached to the top cover;
a sliding seat disposed slidably within said connecting seat and having an integral first projection; and
a resilient member disposed between said mounting seat and said sliding seat and biasing said sliding seat to move toward said mounting seat so as to keep said first projection of said sliding seat in contact with said first cam edge of said mounting seat;
wherein said mounting seat further includes a second pivot block extending integrally from said mounting block and having a second cam edge, and a mounting groove disposed between said first and second pivot blocks, said wing plates of said connecting seat being located respectively to two opposite sides of an assembly of said first and second pivot blocks of said mounting seat, said connecting seat being connected pivotally to said first and second pivot blocks of said mounting seat;
wherein said knuckle arm further comprises a pivot rod extending through said wing plates of said connecting seat and first and second pivot blocks of said mounting seat;

Abstract
A knuckle arm is connected to a machine body and a top cover of a machine, and includes a mounting seat, a connecting seat, a sliding seat, and a resilient member. The mounting seat includes a mounting block disposed fixedly on the machine body, and a pivot block extending integrally from the mounting block and having a cam edge. The connecting seat is connected pivotally to the pivot block of the mounting seat, and is attached to the top cover. The sliding seat is disposed slidably within the connecting seat, and has an integral projection. The resilient member is disposed between the mounting seat and the sliding seat, and biases the sliding seat to move toward the mounting seat so as to keep the projection of the sliding seat in contact with the cam edge of the mounting seat.
