Preferably, the base is provided with a claw frame in a rotating manner. The goat's horn frame plays the supporting role, and the initiative setting makes things convenient for the rotation of support, can rotate the angle at will on the goat's horn frame such as stock and fishing rod place.

Preferably, the inside of the goat's horn frame is provided with an insert, the goat's horn frame is connected with the base through a screw, and the screw penetrates through the base to be matched with the insert. The screw connection is fixed effectual, through the inserts as the intermediate junction spare, can make fixed effect better under rotatable condition.

Preferably, the insert is of a cylindrical structure with a threaded hole inside and anti-slip teeth outside. The antiskid tooth that the outside was equipped with can play the effect that the rotation goat's horn frame did not skid, also can play firm effect to the goat's horn frame after the turned angle simultaneously, under the condition of not exerting external force, the goat's horn frame is difficult for rotating.
