Support arm

A support arm for supporting a display monitor on a support member, the support arm comprising:

• a support mechanism comprising:
• a support plate having a first pivot pillar for being detachably disposed on the support member;
• and
• a first pivot base having a first eccentric rod and sleeving the first pivot pillar to be rotatable relative to the support plate;
• a wall-mounted mechanism comprising:
• a wall-mounted plate detachably disposed on the display monitor and having a second pivot pillar;
• and
• a second pivot base sleeving the second pivot pillar to be rotatable relative to the wall-mounted plate;
• and
• an arm mechanism comprising:
• a casing;
• an arm body disposed in the casing and having a first pivot end and a second pivot end;
• a first spring disposed in the arm body, two ends of the first spring being connected to the arm body and the first eccentric rod respectively;
• a first shaft passing through the first pivot base and the first pivot end to make the arm body rotatable relative to the first pivot base;
• a second shaft passing through the second pivot base and the second pivot end to make the arm body rotatable relative to the second pivot base;
• and
• a first damping member sleeving the first shaft for increasing a rotating torque of the first shaft relative to the first pivot base.
