The multi-site CPU heat sink mounting apparatus of claim 6, wherein: the gear set (32) comprises a transmission rod (321) arranged on the base (1), an upper gear (324) rotatably sleeved on the transmission rod (321), a lower gear (325) rotatably sleeved on the transmission rod (321) and a coaxial component (4) arranged between the upper gear (324) and the lower gear (325), wherein the coaxial component (4) is used for controlling the upper gear (324) and the lower gear (325) to be coaxially fixed or coaxially rotatably connected.

8. The multi-site CPU heat sink mounting apparatus of claim 7, wherein: coaxial part (4) include with last gear (324) slip locking post (41) of being connected and set up elastic component (42) on base (1), draw-in groove (326) have been seted up on lower gear (325), locking post (41) are followed when last gear (324) axis of rotation direction slides and are pegged graft the cooperation with draw-in groove (326), the bottom of locking post (41) is provided with the inclined plane towards lower gear (325) direction of rotation when the screw is screwed up, and elastic component (42) are used for supporting tight locking post (41) so that the inclined plane of locking post (41) support the border of tight draw-in groove (326) and then promote lower gear (325) and rotate.

9. The multi-site CPU heat sink mounting apparatus of claim 8, wherein: the locking columns (41) and the clamping grooves (326) are in one-to-one correspondence, and the locking columns (41) and the clamping grooves (326) are distributed at equal angle intervals along the circumferential direction of the lower gear (325).

10. The multi-site CPU heat sink mounting apparatus of claim 8, wherein: the transmission rod (321) is connected with a sliding rod (322) in a sliding mode along the direction of the rotating axis of the upper gear (324), the end portion of the sliding rod (322) is abutted to the elastic part (42), a screw rod (323) is connected to the transmission rod (321) in a threaded mode along the sliding direction of the sliding rod (322), one end of the screw rod (323) is abutted to the sliding rod (322), and the screw rod (323) drives the elastic part (42) to stretch and retract when rotating so as to adjust the torsion after the screw is locked.
