New description: [New technical field] This creation department is about an additional carrier for bicycles. [Prior Art] In the conventional bicycle frame, there is a bicycle frame such as a parent-child bicycle disclosed in the TWD Secret No. 69 patent, which can be used for parent-child sharing, but such a bicycle is used after the child grows up, or when the adult goes out alone. The auxiliary handlebars and auxiliary cushions for children take up a lot of space, causing inconvenience in riding. [New Content] The main purpose of this creation is to provide a bicycle for parent-child sharing, and to provide a comfortable riding effect when the adult is riding alone. In order to achieve the above object, the present invention provides a bicycle sub-frame for assembly in a bicycle, comprising a main pole, wherein the main pole is provided with a portion and a grip for the user to ride on both ends of the main rod. A fixing portion is defined, and a fastening groove is defined in each of the fixing portions, and two extension plates are further disposed on the main rod, and the two extension plates and the main rod defining-positioning groove are provided at the free ends of the extension plates. - Pedal, the free ends of each of which extend toward the side remote from each other. By this means, the two buckles can be used to assemble the main rod to a bicycle bicycle frame and the bicycle frame is partially accommodated in the positioning groove, and the two extension plates or the main body are adapted to the bicycle. The frame allows the creation to be assembled or disassembled and provides a stable ride. [Embodiment] 3 The following is only to illustrate the creative spirit of this creation, but it is not intended to limit the scope of the creative protection, and the creative spirit of this creation should be covered in the scope of the creation of this creation. Within the first, the first description. Referring to Figure 1, the present invention provides a bicycle sub-frame raft that is used in a bicycle 2 and includes a main rod 11, a grip 12, a portion 13 and a tread portion 14. A fixing portion 111 may be disposed at each end of the main rod 11 for defining a first buckle groove 112 with a bicycle-assembling fixing portion at a front end of the main rod, and is defined at a fixing portion of the rear end of the cold main rod. a second buckle groove 113 is disposed such that the first buckle groove 112 extends in a direction substantially parallel to the main rod 11. The second buckle groove 113 extends in a direction perpendicular to the main rod 11 in another embodiment. Alternatively, the first buckle groove may be slanted to the fixing portion of the rear end of the main rod, so that the positions of the first and second buckle grooves are exchanged. Each of the two fixing portions may be provided with a pressing device, and each of the pressing devices includes a shaft 15 and a screw 152 and a pressing block 153 ′ at the end of the shaft 151 - the screw 152 ' is screwed on the shaft The other end is provided with the pressing block 153, wherein the pressing block can be protruded from the protruding block, or can be disposed as a cam handle, and the pressing block 153 is pivoted on the shaft 151. It can be yawed relative to the shaft. The main rod 11 is respectively provided with a riser 114 and a grip tube. The grip 12 is disposed at the free end of the grip tube 115, and the seat portion 13 is disposed at the free rise of the riser 114. The person rides on the seat 13 and holds the grip 12 by hand to facilitate balance. The step portion 14 includes two extension plates 141 and two pedals 142. Referring to FIG. 4, the two extension plates 141 are respectively disposed at one end of the main rod η and the other ends are spaced apart from each other by the two extension plates (4) and The charm rod u is fixed to the positioning groove 16. The two pedals 142 are respectively disposed at the free end of one of the extension plates 141, wherein the two pedals 142 can be respectively bent and extended by the two extension plates 141, or the other plate body gj can be disposed on the extension plate. The shafts, the free ends of the two pedals 142, extend toward one side away from each other. Referring to FIG. 1B, in another embodiment, the connecting plate 143 can also be formed on the two extension plates 141, so that the tread portion can be formed by folding the plate body f, which makes the creation easier. The positioning groove 16 is still defined between the two extension plates 141 and the main rod n. Referring to Fig. 1', the creation can be assembled in a bicycle 2 including a bicycle frame 21, a front fork 22 and a rear 23. The bicycle frame includes a rod body 2, a front tube 212 and a tube 213. The two ends of the rod body 211 are respectively fixed to the front tube 212 and the seat tube 213, and a buckle portion 24 is fixed to the front tube 212. Another buckle portion 24 is fixed to the seat tube, and each of the buckle portions can be actually set as a short tube. The front 22 is rotatably disposed on the front tube 212. The front fork 22 is provided with a front wheel 221 ', and the front fork 22 is provided with a bicycle handle 222 for rotating the front fork 22 and the front wheel 221 to control the movement of the bicycle. direction. The rear fork 23 is fixed to the seat tube 213, and is further provided with a rear wheel 23. In other embodiments, the rear fork can also be fixed to the rod body or other positions of the bicycle frame. The rear fork is located on a side of the bicycle frame that is away from the front fork. The bicycle frame 21 and the rear wheel 231 may be provided with a power unit such as a gear chain group or a motor. However, the power unit is not provided, and the user can directly advance with the ankle. Therefore, the present invention can be assembled, and the first buckle groove 112 can be firstly engaged with one of the buckle portions 24, and then the main rod 11 can be rotated, so that the second buckle groove 113 can be vertically fastened to the other buckle portion 24. As shown in FIG. 2 and FIG. 3, the bicycle sub-frame is assembled in the bicycle, so that the two ends of the main rod 11 are respectively detachably disposed on the front tube 212 and the seat 213, so that the two extension boards The 141 is placed on both sides of the rod body 211 so that the body is located between the two extension plates 141, and the rod body 211 is partially accommodated in the position. In the $-solid towel, the second button can be fixed on the rod body. 7. Both ends of the main rod are detachably disposed on the rod body. Then, the arranging rods can be used to pass the arranging rods to the respective fastening portions 24 and 24, so that the shackles L and the slabs 152 are respectively disposed on the screws 152 and the urging blocks 153. between. In summary, the bicycle sub-frame provided by this creation can be installed in the self and in the middle and can be transferred. The towel is fixed to the bicycle, and the rod of the Hong Kong The pasteable extension domain secrets against the benefit of 'making the bicycle passenger car inspection-step and bicycle fixed each other, providing a detachable heart-shaped ride effect, which is a proof of progress.
