Taking four unit base modules 1 as an example: (see fig. 8) the adjacent unit base modules 1 are spliced and combined in the direction of fig. 7.

The invention has the advantages that the material of each unit base module 1 is easy to obtain, the structure is simple, and the weight of a single piece is light; the cross plate 3 is supported, and the triangular support is stable in structural support; the bottom plate 4 is arranged for increasing the stress area of the pole-holding modularized base and the ground and preventing the base from sinking.

After the modules are combined, the upper parts of the modules are used for connecting different support I-beams, and the support I-beams can be used as holding pole bases with different specifications, so that the universal design of the bases is realized.

The invention prefers the left, right, inner and outer vertical connecting lock plates 5 to connect the adjacent two modules in a pin joint and socket combination way with different coordinate directions, the connection is more reliable and firm, and the base support structure of the modularized combination is more stable.

In summary, the invention adopts the unit base module which can be combined and modularized, and the modules are spliced and combined through the pin shaft locking structure between the modules to form the required size, so as to solve the technical problems of complex structure, huge volume, inconvenient transportation and turnover and non-universal use of the existing holding pole base.
