The invention provides a linear driving mechanism which comprises a machine shell, a front cover, a rear cover, a stator and a hollow rotor, the front cover and the rear cover are fixed to the two opposite ends of the machine shell respectively, the stator is arranged in the machine shell, the rotor is arranged in the stator and is hollow, and the stator drives the rotor to rotate; the linear driving mechanism further comprises a rolling screw rod sleeved with the rotor, a first bearing arranged on the rotor in a sleeving mode and fixed to one end of the rear cover, and a second bearing arranged on the rolling screw rod in a sleeving mode and fixed into the machine shell. The rolling screw rod comprises a central screw rod arranged on the inner circumferential side of the rotor and a screw rod nut arranged on the central screw rod in a sleeving manner; the lead screw nut is formed on the inner circumferential side of one end, close to the front cover, of the rotor. According to the linear driving mechanism, t
