New description: [New technical field] The present invention provides a technical field of folding bicycle towing and telescopic fixed structure, in particular, it provides a folding bicycle tow steering telescopic fixed structure, and its adjustable seat The chair lifts and ensures that the seat is turned positive and its pulley is also turned positive to ensure safe driving. [Prior Art] According to the bicycle, the bicycle has the advantage of not using fuel, and the bicycle does not cause environmental pollution. Therefore, it is deeply loved by the public and will not be forgotten because of the long time. The effect, so the equipment, three are the means of transportation. On the other hand, the use of bicycles is one of the means of transportation and the other is sports. The bicycle needs to be designed according to the height ratio of the user. The total volume of the two wheels is quite large, if it is to be placed behind the car. The suitcase is either to carry the MRT system, and the large size will cause considerable trouble. Therefore, more and more people are now switching to folding bicycles, and the bicycles are convenient to transport or The building line, Xiao Xi used to fold from: When the towing wheel of the car is towing and riding, the big Dan is different from the one, and if the tow is riding, the towing wheel will be perpendicular to the direction of travel. A & The elbows can be quite dangerous, and the conventional folding bicycle cannot be adjusted so that the adult can ride the state of the week' so there is still considerable room for improvement. Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop M381572 more innovative and practical structures, consumers are eagerly awaiting, and the relevant industry must strive to develop breakthrough goals and directions. In this case, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation, the creator has finally achieved a practical and practical creation. [New content] The bicycle needs to occupy a considerable range according to the overall volume of the user's or to carry the technical problems to be solved by the MRT system: the design of the height ratio is used, and if two wheels are to be placed in the brakes, The rear luggage compartment 'causes the bulk of the volume will cause considerable trouble, so nowadays more and more people use folding bicycles. 'With this (four) bicycle, it is convenient to carry and carry the towed wheel of the conventional folding bicycle. When towing and riding, the direction is different' and if the towing wheel is perpendicular to the direction of travel when riding, it will be dangerous, and the conventional folding bicycle cannot be adjusted to a state in which the adult can comfortably ride, so there is still quite Great room for improvement. Technical features of the problem: a telescopic fixed structure, the seat tube fixes the first bundle, and the first bundle is provided with the first tube passing through the seat tube, and the middle bundle is provided with the first "^, a' A convex portion, a body, and a seat tube protrusion body are fixed at the top end of a rod, so that the seat rod is limited to provide a finger-folding bicycle towed to the frame, and the top end of the seat tube is provided with a slot and a positioning slot, A second beam member is disposed on the top end of the bottom end pulley, and the second first beam member is provided with a bump inside the middle tube. The circumference of the pedestal rod is provided with a grooved clamping mid-lower or the second bundle is tightly fixed, and when the M381572 seat is rotated by 90 degrees, the middle tube and the pulley are also rotated 90 households and the first and second The positioning convex portion is locked by the first and second positioning grooves, and the mouth is used for towing. When the seat is turned positive, the middle tube and the pulley are also turned positive to ensure that the pulleys are in the same direction to ensure safety. Compared with the effect of the prior art: the artificial folding tow steering telescopic fixed structure of the present invention can ensure that the pulley is also rotated positively while the seat is turning positively to ensure the safety of the driving, and the seat is combined with the seatpost Adjustable lifting height for adult riding. A description of the techniques, means and functions used in this creation, and a better example and with the m 4 „ 配 口 图 坪 坪 , , , , , , , , , , , , , When it is possible to obtain an in-depth and specific understanding. [Embodiment] Referring to the first to sixth figures, the present invention provides a folding bicycle towing steering telescopic fixing structure, comprising: a seat f (1 0 ), The seat tube (10) is fixed to the bicycle (i >> frame f9, the center, the upper end of the seat tube (10) is provided to the rear circumferential surface - the first split groove (1 1 );固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定a first beam (2〇) 1 ) aligned with the first trough (1 1 ), the first surface being perpendicular to the first actuator (2 1 ) (2 2) and a second positioning groove 5 M381572 a middle tube (30), the middle tube (30) is disposed in the seat tube (1 Ο), and the middle tube (30) can be rotated and adjusted by 360 degrees Slip adjustment, the middle tube (3 0) a pulley (3 1 ) is pivoted to the rear of the bottom end, and a second slot (32) and a third slot (33) are disposed on the side of the top end of the middle tube (30); a second beam member (40), the second beam member (40) is fixed to the top end of the middle tube (30), and the second beam member (40) is provided with a second actuation portion (4 1 ) aligned with the second beam member (40) a second positioning groove (32), wherein the second beam member (40) is disposed in a direction perpendicular to the second actuation portion (4 1 ), and is respectively provided with a first positioning convex portion (42) and a second positioning a convex portion (43), and the second beam member (40) is provided with an inward convex block body (4 4 ) aligned with the third cutting groove (3 3 ), the convex body (4 4 ) After the three slots (3 3 ), protrude into the inner hole of the middle tube (30); and, a rod (50), a seat (60) is fixed at the top end of the seat rod (50), a groove (5 1 ) is disposed on a right side of the seat surface of the seat post (50) perpendicular to the direction of the seat (60), and the seat rod (50) is inserted into the inner tube (30), the groove The slot (5 1 ) is snapped into the bump body (4 4 ) so that the seat post (50) can only be lifted or lowered, or the second bundle member (40) is tightened and fixed. When the seat (60) rotates 90 degrees, it will also drive the middle tube (30) and the pulley (3 1) to rotate 90 degrees, and the first and second positioning protrusions (4 2), (43) The first and second positioning slots (22) and (23) are engaged and positioned for towing, and the seat (60) is rotated to the middle tube (3 0 6 M381572 is) and the pulley (3 1) is also Turn positive to ensure that the pulleys are in the same direction when traveling to ensure safety.
