Tool for installing curb

The invention discloses a curb mounting tool which comprises rotating arms, the joint of the rotating arms on the two sides is hinged, a clamping plate body is fixedly arranged at the bottoms of the rotating arms, the clamping plate body is in an L shape and is perpendicular to the ground, and adjusting mechanisms are slidably arranged on the two sides of the clamping plate body; when a curb needs to be clamped, a guide block and a trapezoidal block slide in a matched mode to enable a follow-up plate to move upwards, then an elastic telescopic column is driven to contract, a clamping plate body and a sawtooth strip on the outer side of a side clamping plate tightly extrude the curb, clamping points of the curb can be evenly distributed, and the curb clamping effect is improved. And the adjusting mechanism is adjusted according to the length of the curb, the sliding plate slides front and back, the overlapped groove holes of the sliding plate and the clamping plate body are locked through the locking pin, the
