Through above-mentioned technical scheme, in the in-service use, drive the spring pearl through expanding spring and carry out concertina movement at expanding spring's length direction to realize the spring pearl joint in the joint inslot of difference, and then realize the expansion joint of butt piece and U type pole.

Furthermore, the cross-sectional area of one end, far away from the U-shaped rod, of the abutting block is larger than that of the U-shaped rod.

Through above-mentioned technical scheme, in the in-service use, the area of butt piece is great, prevents that the butt piece from getting into U type pole completely in, can not dismantle the operation.

Furthermore, the ejector pin piece comprises an ejector pin block detachably connected with the U-shaped rod and an ejector pin bolt with a thread penetrating the ejector pin block.

Through above-mentioned technical scheme, in the in-service use, the knock pin piece can be dismantled and be connected U type pole, and the knock pin bolt is used for dismantling the operation with the butt piece.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) through the detachable ejector pin piece, the interference connection parts with different sizes can be detached by using different ejector pin pieces, so that the detachable ejector pin piece is suitable for detaching the interference fit parts with different sizes;

(2) furthermore, the abutting block is connected to one end of the opening end of the U-shaped rod in a telescopic mode, and interference fit parts of different sizes can be detached through the matched ejector pin piece.
