An obliquely staggered state, thereby causing one side of the card block 30 to be caught on the inner wall of the front fork riser 40 to cause interference, so that the seat bar member 10 can be fixed to the front fork riser 40 without Will be separated.

The use state of the first preferred embodiment of the present invention is as shown in FIG. When the front fork riser 40 or the faucet riser 50 generates upper and lower vibrations in a place where the road surface is undulating, the movable member 20 will be displaced toward the seat member 10, so that the movable seat 21 is displaced. The upper and lower displacements are generated along the shaft tube 13, and the two guide posts 24 also extend toward the first guide post hole 116, and the compression spring 14 is compressed to generate a cushioning effect, thereby slowing down the front. The vibration generated by the displacement of the fork riser 40 or the faucet riser 50 up and down, and the cooperation of the two guide posts 24 and the cushioning pad 23 can assist the guiding and reduce the noise generated during the compression.

A second preferred embodiment of the present invention is shown in FIGS. 9 and 10. The difference is that the two first guide post holes 116A of the seat member 10A are screw holes, and the two second guide post holes 214A of the movable member 20A are through holes. Two guide columns 24A In the lower stage, the threaded portion 241A is passed through the two second guide post holes 214A, and the threaded portion 241A is screwed and fixed to the two first guide post holes 116A. Therefore, when the seat post is When the member 10A is relatively moved with the movable member 20A, the two guide posts 24A are fixed to the seat member 10A without causing relative movement with the movable member 20A.

The novel system can be assembled and coupled to the front fork stand relatively easily The tube 40 and the faucet riser 50 are small in size, simple in structure, and have the advantages of being lightweight and convenient to carry, and can be arbitrarily combined with various bicycles without requiring a considerable time to assemble, which is quite practical and convenient.

The above description is only a preferred embodiment of the present invention, and it is not The present invention is to be limited in any form, and any one of ordinary skill in the art may, if not departing from the scope of the technical features of the present invention, the equivalent implementation of the local modification or modification made by the disclosed technology. For example, they are still within the scope of the novel technical features.
