Under the elastic resetting action of the resetting member, one end of the positioning rod moves toward the inside of the receiving groove, so that the other end of the positioning rod is engaged with the positioning groove, and then the positioning screw is driven to rotate by turning the handle so that the end of the positioning screw is threadedly connected with the threaded hole, so that one end of the positioning rod is stably engaged in the positioning groove, so that the mounting plate and the fixing plate are firmly connected, which is convenient for the claw head to be quickly installed and fixed to the starting box of the bus duct, thereby improving the efficiency of later disassembly and assembly.

[0019] 2. In the utility model, through the installation mechanism provided, when the claw head is installed, one end of the claw head is inserted into the slot, and the rotating rod is used to drive the bidirectional screw rod to rotate, so that under the action of the threaded pair, the two sleeves are relatively moved along the length direction of the bidirectional screw rod. When the sleeve moves, it will drive the connecting plate to move, thereby driving the limit block to move, so that the limit block is engaged with the limit groove, thereby fixing one end of the claw head, and cooperating with the rotating thread sleeve to make it abut against the outer surface of the fixed plate, thereby preventing the rotating rod from rotating. According to the above steps, multiple claw heads can be installed at the same time, which is convenient and quick to install the claw heads according to the required number.
