Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, the utility model discloses a portable lift pawl mechanism, including base 9, fixed column 1, rocking arm 4, rocking arm connecting axle 7, T type commentaries on classics cover 8 and cylinder 11, rocking arm 4 is installed at the both ends of rocking arm connecting axle 7, and T type commentaries on classics cover 8 is installed to the centre of rocking arm connecting axle 7.

Two linear bearings 14 with seats are arranged below the base 9, the mechanism is arranged on two guide shafts of the equipment through the linear bearings 14 with seats, and the mechanism can be moved to different positions through other power mechanisms on the equipment.
