When the operating lever is rotated, the free end 252 of the spring bar will rotate integrally with the rotating rod ′ and accumulate the returning elastic force; t release the operating lever, then the operating lever will return to the original position according to the returning elastic force of the spring lever. The following is a detailed description of the embodiment with reference to the drawings, which will be clearly shown. FIG. 1 to FIG. 5 are respectively a schematic view showing the appearance of a pedaling vehicle according to an embodiment of the present invention, and (4) a large image of the device (4). Exploded view, section view and side view. As shown in the drawings, a bicycle-mounted vehicle according to the present invention includes a carrier unit (10) and a plurality of fixing devices 2 disposed in the vehicle unit. The carrier unit is left as a trailer, and has a carrier plate ιι and a pair of wheel bodies 12 pivoted on the bottom surface of the carrier plate 110. Please - and as shown in Figure 6, the carrier UGG can be towed by the vehicle, and the outer M378920 of the carrier unit (10) is provided with a cover 130 such as a canvas cover to cover the interior of the carrier unit 100. Delivery. Each of the fixing devices 200 includes an obstructing unit 210 and an opposite first wheel frame 220 and a second wheel frame 230, which are respectively disposed at two ends of the track unit 210. The obeying unit 210 includes a plate body 211, a body 212 and a tooth row 213. The plate body 211 is disposed on the top surface of the carrier plate 110; the rail body 212 is disposed on the top surface of the plate body 211; and the tooth row 213 is disposed on the top surface of the plate body 211 and located at a side of the body 212 Position, and the tooth row 213 has a plurality of concave teeth 214. The first wheel frame 220 and the second wheel frame 230 each include a groove body 221 and an arc frame body 222. The trough body 221 is slidably disposed on the body 212 of the obliging unit 210; the arcuate frame body 222 is disposed on the top surface of the trough body 221, and the arcuate frame body 222 has a curvature corresponding to the wheel body 410 of the bicycle 400, and is curved. The inner wall of the frame 222 is covered with a slip-resistant lining 223 to provide a slip-stop effect on the pedal body 410. • The first wheel frame 220 and/or the second wheel frame 230 are provided with a positioning unit 240 that meshes or disengages from the tooth row 213 of the obstruction unit 210. Hereinafter, the positioning unit is provided in the first wheel frame 220 for explanation. The positioning unit 240 includes a first fixing member 241 and a second fixing member 242, and an operating lever 243. The first fixing member 241 is disposed on the top surface of the groove body 221 at a distance from the second fixing member 242. The operating lever 243 has a connecting rod 244 and a handle 245. The rotating rod 244 is pivotally disposed on the first fixing member 241 and the second fixing member 242, and the rotating rod 244 is connected with a braking member 246. The direction of the tooth row of the unit 210 is provided with a convex tooth 247 7 M378920. When the operating lever 243 is rotated, the braking member 246 is integrally driven to cause the protruding teeth 247 on the brake pad 246 to mesh with the concave teeth 214 of the tooth row 213 (as shown by the solid line in FIG. 4) or to separate the phases ( As shown by the dotted line in Figure 4). The rotating rod 244 is connected with a connecting piece 248 adjacent to the first fixing member 241, and the positioning unit 240 further has a spring rod 250 having opposite ends. A fixed end 251 and a free end 252 are respectively set. The second fixing member 242 and the connecting piece 248 are disposed. When the operating lever 243 is rotated, the free end 252 of the spring bar 250 is integrally rotated with the rotating lever 244 and accumulates the returning elastic force; when the operating lever 243 is released, the operating lever 243 is biased by the returning force of the spring lever 250, The operating lever 243 is returned to the original position. A footrest vehicle according to an embodiment of the present invention can be used to secure the bicycle 400 with a plurality of fixtures 200 provided on the carrier unit 100. When the bicycle is fixed, the bicycle 400 is placed between the first wheel frame 220 and the curved frame body 222 of the second wheel frame 230 with its front and rear wheel bodies 410; then, the operating rod 243 is rotated to make the bicycle 243 The protruding teeth 247 of the braking member 246 are disengaged from the concave teeth 214 of the I-tooth 213 (as shown by the dashed line in FIG. 4), so that the first carrier 220 slides on the track unit 210 to adjust the first a distance between the wheel frame 220 and the second wheel frame 230 to suit the wheel track between the front wheel and the rear wheel body of different bicycles 400 (as shown in FIG. 5) for firmly clamping the bicycle 400; Then, the operating lever 243 is released, which returns to the original position according to the return elasticity of the spring rod 250, so that the convex teeth 247 of the braking member 246 of the operating rod 243 are again engaged with the protruding teeth 214 of the tooth row 213 (eg, 4 is shown by the solid line), and the positioning state is maintained. Thus, the bicycle 400 can be firmly fixed to the fixture 200. 8 M378920 In order to make the bicycle 400 more securely fixed to the fixing device 200 of the carrier unit 100, the bicycle device according to an embodiment of the present invention is further fixed to the top surface of the carrier 100 of the carrier unit 100. A fixed post 300 is pivotally mounted to the position of the device 200. In the normal case, the fixing post 300 is flatly attached to the top surface of the carrier 100 so as not to affect the obstacles on the handling of the bicycle 400. In use, the fixing post 300 is erected perpendicularly to the carrier 100 for supply. A lock member (not shown) locks the bicycle 400 with the fixed post 300 and has an anti-theft function. • When the vehicle 500 is carried by the vehicle 500 and the vehicle unit 100 is towed to the destination, if the bicycle 400 is to be unloaded, the lock member is disengaged and the operating lever 243 is rotated to disengage the convex teeth 247 of the brake member 246. Engaged with the concave teeth 214 of the tooth row 213, and pushes the first wheel frame 220 to slide outward on the track unit 210 to increase the distance between the first wheel frame 220 and the second wheel frame 230. The bicycle 400 can be easily removed from the fixture 200. Alternatively, the fixture 200 can be attached to a stationary carrier surface (e.g., the ground) for display and securing the bicycle 400. The fixture has exactly the same construction, operation and efficacy as the fixture 200 of the carrier unit 100 described above. The pedaling vehicle and the fixing device thereof according to an embodiment of the present invention have at least the following advantages: (1) The adjustable distance between the first wheel frame 220 and the second wheel frame 230 of the fixing device 200 is adapted to various Different bicycles 400 have different applicability; (2) The bicycle 400 is firmly fixed between the first and second wheel frames of the fixing device by the front and rear wheel bodies, and has good fixing property; (3) The bicycle is locked to the fixed column 300, and the 9 M378920 has the function of stability and anti-theft; (4). Because of the boundary of the fixing device 2, the bicycle 400 is between each other or with the vehicle unit 1 There will be no collision between the rafts, and the integrity of the bicycle will be maintained. (5) The bicycle 4〇〇 is exposed inside the cover 130 of the vehicle unit 1〇〇, and will not be exposed to the sun and rain during long-distance transportation. And the erosion of the wind, to maintain the life expectancy of the bicycle; (6) Carrying the bicycle with the vehicle unit 100 in cooperation with the vehicle 500, the vehicle can be carried at the same time, carried, and the carrying capacity is good.
