The 1378053 seat body (531) is provided with two ends; Preferably, the two ends of the base body (531) are respectively provided with a yoke recess (5311) and a tab (5313), and each of the yoke recesses (5311) is recessed corresponding to the seat body (531). The end portion has a semicircular cross-sectional shape, and each of the fins (5313) extends horizontally and is integrally coupled to the corresponding abutting recess (5311); the two pivoting systems are respectively pivotally disposed at opposite ends of the seat body (531) Different from the two recessed portions (5311) and the two protruding pieces (5313), the two pivoting systems are respectively detachably fixed to the rod body (513) and the second tow bar (315); The second tow bar (315) is fixedly coupled to the quick release seat (53), so that the telescopic frame (313) can be fixed and the base frame (311) can be horizontally displaced relative to the telescopic frame (313); Each of the pivoting systems includes a clamping piece (533) and a quick release shaft member (535). Each clamping piece (533) is provided with a clamping recess (5331) and an abutting portion (5333). The recessed portion (5331) has a semi-arc shape and the openings of the respective recessed portions (5331) are oriented toward the corresponding abutting recesses (5311); the respective abutting portions (53 3 3 3) are horizontally extended and integrally coupled to each other. The clip recesses (53 3 31) and abut against the corresponding tabs (5313); each quick release shaft member (535) is vertically erected and fixed to the corresponding tab (5313) and abuts The part (5333); the quick release shaft member (535) belongs to the prior art member, and the detailed structure thereof is not described herein. As shown in the first and sixth figures, the present invention is installed in a conventional bicycle (B). The bicycle (B) is provided with a tube (B1) and a rear axle (B2); the assembly mechanism of the present invention The bracket (1531) of the fixing frame (153) of (15) is fixed to the seat tube (B1) of the bicycle (B). The bracket (1531) can be fixed by welding or quick-release sleeve fitting. It is located in the seat tube (B1), and the hair 137053 (51) can be connected. In other words, the fixing rod (51) can also be directly fixed to the sleeve seat (511), and the quick release seat (53) utilizes the bearing. The method is rotatably sleeved on the pry bar (51), and the form of the fixing bar (5丨) and the quick release seat (53) is not particularly limited in the present invention. As shown in the first and ninth figures, the trailer unit (3〇) can be removed from the quick-release group (5〇) as a general trolley trailer, which is excellent in practicality and convenience. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and the simple equivalent changes and modifications made by the scope of the present invention and the contents of the specification. All should remain within the scope of the invention patent. BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is a perspective view of a preferred embodiment of the present invention.
