The arrangement of the long groove optimizes the structure of the clamp main body 100, and reduces the occupied space of the section clamp; by means of the structural improvement, the clamping/loosening action of the profile piece in the first direction is finished by the pawl piece 200 in a mode of moving along the first direction, the risk that the pawl piece 200 is separated from a movement track can be greatly avoided, and the smooth work of the profile clamp is effectively guaranteed; meanwhile, due to the design that the claw pushing convex block 210 extends out of the long groove, the direct friction between the bottom of the profile piece and the top of the claw pushing piece 200 can be effectively avoided under most conditions, and therefore the risk of damage to the profile piece in the clamping process can be effectively reduced.

Further, the clamp body 100 is provided with a pushing member capable of driving the claw member 200 located at the release position to move to the clamping position, and a reset member driving the claw member 200 to stop at the release position. Due to the arrangement of the pushing piece and the reset piece, the accurate positioning of the pusher 200 at the loosening position and the clamping position by an operator is facilitated, and the pusher 200 can stop at the position set by the operator due to the design that the pusher pushes the pusher 200.
