Detailed description of the invention

Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.

Shown in Fig. 1, a kind of light-duty shock-resistant column, comprise that column 19 bottoms are provided with mounting seat 2, described column 19 front ends are provided with front wall 16, and rear end is provided with rear wall 14, and both sides are all disposed with straight wall 4, tool magazine installed surface 7 and sloping core 3, inside is provided with several floors 12,121,122,123, described front wall 16 tops are provided with motor mount 1, and bottom is provided with screw mandrel bearing mounting base 15, and both sides are provided with projection 18.

Further, described floor 12,121,122,123 mid portions are provided with sand removal lightening hole 13.

Further, described sloping core 3 bottoms are arranged at mounting seat 2 tops, and on the metope of described sloping core 3, are provided with some lifting eyes 8, and the quantity of described lifting eye 8 is at least 2.
