[Prior Art] A general folding bicycle can reduce the overall size, which is convenient for handling and stopping, and is popular among consumers of the fork. However, a bicycle that is folded in a roundabout manner will have a h-shaped shape in which the front and rear wheels interfere with each other because the frame extends in a linear direction. Therefore, the front wheel must be unloaded from the frame before being folded. It is slow and can cause problems in use. Therefore, in order to improve the lack of the above-mentioned spiral folding bicycle, the applicant of the present invention applied for the "folding bicycle" invention specifically for the purpose of pivoting a front frame of the bicycle in a horizontal direction. And the rear frame rod, and the pivot shaft forms an inclination angle with the extension direction of the front and rear frame rods instead of being orthogonal, whereby the front and rear frame rotation folding days 3 are relatively staggered to form one The spacing between the front and rear wheels. The case is not satisfied by this case, and still adheres to the lean spirit and continues to engage in relevant development research. Therefore, it is found that the buckles disclosed in the original invention/order still have a simplified space in the structure ^, The inventor of this case has been continually pondering and using Qiaozhi, and actively concentrating on it; research and development have finally come out with the invention. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a simplification of the structure. The folding bicycle of the present invention comprises a frame unit. The frame unit has a front car extending along the axis-axis and a fish. (1) Dry 4' and pivoting the front frame and the rear rudder in a horizontal direction: the axis 'the pivot is formed with the axis - angled rather than orthogonal, such that: the rear frame surrounds the pivot When the gyroscopic folding is folded, a pair of -m2 splicing (four) splicing has a splicing device. The splicing device has a reversely extending two H 鳊 and a positioning end, and the pivoting end is pivoted with the front frame. The setting: 3⁄4疋 can be positioned on the rear frame when the front and rear frames are extended, so that the Z rear frame and the buckle form a mutually impinging limit relationship and obtain the effect county of the present invention. Table t VL_ π Μ ^ ,. Sex simplification of components, simple operation when using 【 [Embodiment] The foregoing and other technical contents, features and effects of the present invention are compared with the reference pattern of W. In the detailed description of the preferred embodiment, it is clearly presented. The preferred embodiment of the folding bicycle of the present invention comprises a rutting unit 1, an extension positioning device 2 and a folding positioning device 3. The cedar wood has a front frame 11 and a rear frame 12 and a pivot 13 extending along an axis. The mountain, the rear sill, and the rear sills U and 12 respectively have a yam mountain formed at a rear end portion and a front end portion. Oblique matte m, 121, and a pivot 112 and a pair of ear sockets 122 respectively formed at the lower end of the oblique surface ill 12 ι and respectively, and respectively formed on the inclined end surface m' 121 and mutually a fitting - 1254683 block 113 (Fig. 7) and a slot 123 (see Fig. 7), and the rear frame 12 has a tube 124 extending from the top to the bottom, and a pair extending rearward from the seat tube The rear fork set 125, and a rod ι26 that is placed in the seat tube 124. The cymbal 13 is a lug 122 that penetrates the rear frame 沿 2 in the horizontal direction and the front frame 11 _ ear 112, and has an inclination angle with respect to the axis 而 instead of being orthogonal.

The hook claw 213 is hooked on the shaft 231 of the quick release 23 ^ 'the material hook claw 213 is respectively located at the end edge 221 of the C-shaped buckle 22 and the forced portion [between the blocks 232 and then the eccentric pull handle 233 is forced to squeeze the clamp The end of the C-shaped buckle 22 and the hook 213 of the buckle 21 are positioned to position the straight port f 21 between the front and rear frames m. Therefore, in the case that the front and rear/squats 11 and 12 cannot be rotated upward, the front and rear frames u and 12 are formed in a relationship with each other and are mutually constrained, and cannot be Bottom rotation 'reaches the position for riding. > Figure 3, Item 4' When folding the bicycle, it is only necessary to release the quick release 23 handle 233 and disengage the buckle claw (1) from the shaft 231 so that the positioning end 212 of the buckle 21 is formed. Free end, limit the front and rear frames u, 12. In Figure 5 and Figure 6, the 11 and 12 can be lifted upwards to the pivot 13. At this time, the user only has to pull the buckle 21 upward, and the front and rear frames are made during the process of the frame 11. It is the center of rotation, and it is sag downwards with its own gravity equal to 1,254,683, and is relatively rotated and folded. 2, FIG. 7, due to the pivoting angle; therefore, when the buckle 21 lifts the front and rear vehicles up to force, the front frame 11 and the rear frame 12 are both grounded by their own gravity. Drop down and on the front teeth.罜 中 'The rear car... gradually deviates from the axis =: The == :: There is a distance D from the sub-shape, and the income can be folded into the left and right sides without mutual interference. At the time of the mouth, the rear frames 11 and 12 are combined into a folded state in which the left and right sides are juxtaposed to correspond to each other, so that only the coupling member 31 is required to be driven by the latching member 31. Place the 321 ^, ΠΜ 2 « to locate, to avoid a separate situation when carrying. Further, the reference figure is a second preferred embodiment of the present invention, which is substantially the same as the preferred embodiment of the present invention, except that the vehicle has a two-terminal tab 14, 15 further. The terminal pieces Μ and b respectively have end portions 1W, (5) which are fixed to the inclined end faces ln, 121, and a pair of ear holders which can pass through the front and rear frames " M2 and a pivot 152, and a rod 127 connecting the pivot 152 and the seat tube a*, the pivot 13 is horizontally penetrated through the ear seat 142 and the pivot ear μ], so that the front and rear vehicles The frames u, 12 are pivoted together through the terminal pieces 14, 15
