Building template convenient to disassemble and assemble

The utility model discloses a building template convenient to disassemble and assemble, which relates to the field of building templates, and comprises first support plates and second support plates, and two groups of second support plates are arranged on the inner sides of the two groups of first support plates. The two sets of second supporting plates are moved to the inner sides of the two sets of first supporting plates, the clamping grooves are connected with the blocking plates in a clamped mode, the sliding blocks are pulled to move, the sliding blocks push the springs to conduct compression deformation, and the sliding blocks move to drive the limiting rods to be separated from the first limiting grooves; after a limiting frame is rotated to the outer side of a second supporting plate through a connecting shaft, a sliding block is loosened, a spring loses limiting and is reset, the spring pushes a limiting rod to limit a second limiting groove, the positions of a positioning block and the limiting fra
