The present invention is for the technical scheme that is used of its technical problem of solution：
A kind of foldable trailer for bicycle attachment means, including connection main body, connection main body are installed on trailer support body, even
Main body is connect provided with drawbar, drawbar end is connected with bicycle saddle tube by removable connector, wherein：
Connect to have in main body and limited block is provided with converting interface, converting interface, limited block one end is fixedly connected with drawbar, and its is another
One end is installed in converting interface by rotating shaft, limited block is rotated in installing port；
Locating piece is additionally provided with installing port, has the interface arrangment being mutually adapted between locating piece and limited block, locating piece with
The mutual clamping of limited block, makes locating piece be positioned in installing port.
Having on limited block has clamping joint on buckling groove, locating piece, clamping joint is stretched into buckling groove, makes locating piece in peace
Fill intraoral positioning.
Buckling groove have at least one pair of, between each buckling groove centered on rotating shaft curved array arrangement.
Installing port inwall has chute, and locating piece both sides are stretched into chute, and locating piece can be moved along the chute, make locating piece
With limited block clamping or releasing.
Locating piece is provided with projection, and back-moving spring is provided with installing port, and back-moving spring withstands projection, make locating piece with it is spacing
Block clamping is close.
There is grafting termination, drawbar head end is stretched into grafting termination, and is fixedly connected by rivet on limited block.
Connecting has jack in main body, trailer support body is stretched into jack, and is fixedly connected by rivet, connects body top
With handle.
Connecting main body includes mutually fastening between a pair of cover plates, cover plate, and is connected by bolt.
The advantage of the invention is that：
The cover plate bottom of the attachment means is clamped at the top of trailer support body, and is fixed with rivet, passes through bolt lock between cover plate
Fixed, locating piece is pushed by back-moving spring, with limited block clamping, it is necessary to when changing angle, locating piece be pulled up, clamping joint
Deviate from from buckling groove, locating piece is separated with limited block, limited block is rotated to predetermined angular, limited block, back-moving spring is discharged
Locating piece is pushed, clamping joint is stretched into another buckling groove, make limited block and positioning hole clamping, so that drawbar be folded, folded
Simple to operate, volume after folding is small, regular shape, is easy to deposit and carries.
