Driving support and electric steering locking device provided with the same

The invention discloses a driving support and an electric steering locking device provided with the same. A driving support (8) used for driving a support (7) comprises a plate-shaped structural element (9) provided with an accommodation framework (11) and a supporting seat (16). The accommodation framework can be fixedly used for accommodating a driving motor (2) of the driving unit (7). The supporting seat is used to support a free end part (15) of a driving worm shaft (3) coupled with the driving motor (2). The driving support also comprises a baffle block element (10), which can be used to limit at least one axial-direction motion of the driving worm shaft (3). The element (10) is provided with a first baffle block surface (18) and a second baffle block surface (19). The first baffle block surface is disposed between the accommodation framework (11) and the supporting seat (16). The second baffle block surface is disposed on the end part (23) of the end part (15)by adopting the axial baffle block way. The baffle block element (10) is detachably fixedly disposed on the plate-shaped structural element (9), the better steering locking device can be provided in a simple way, and the higher function safety performance can be provided.
