Electric mechanism with locking function

The utility model discloses an electric mechanism with a locking function. The electric mechanism solves the problem that in the prior art, due to the fact that the driving power of a motor in an electric locking mechanism is small, the requirement for certain locking force in any working stroke cannot be met. The device comprises a driving assembly and further comprises an output assembly connected with the driving assembly through a straight tooth transmission assembly. The driving assembly is a driving motor, and the output assembly is a lead screw assembly. According to the utility model,the output capability of the driving motor with relatively low power is indirectly increased through a reliable straight tooth form, so that the cost is reduced; and meanwhile, through the combinationof the straight tooth form and the transmission form of the lead screw assembly, the requirement that certain locking force can be achieved within any working stroke can be met, and the requirementsfor reliability, force bear
