The lightweight seat tube assembly 2 includes a tube 22, a screw 23, and a screw. The head 21 includes a support portion 211 that is inclined to the adjustment cam 212 of the transverse axis 201. The clamping unit comprises: 5 M334808 an adjusting member 221 for clamping the supporting portion 211, a connecting soil 222' for holding the adjusting members 221, and a clamping member 223. The adjustment member 221 has an adjustment side 224 that is parallel to a vertical axis 202 and a mounting surface 225 that abuts the mounting bars 200, respectively. The clamping members 223 each have a fastening surface 226 against the mounting rod 200, a clamping side surface 227 parallel to the vertical axis 202 and abutting the adjustment side surface 224, and abutting the adjustment curved surface 212. Limit surface 228. The screw 23 passes through the clamping side surface 227 and the adjusting side surface 224 along the transverse axis 201. Since the adjusting curved surface 212 is inclined to the lower horizontal axis 201 to generate a downward pressure, the clamping members 223 clamp the same. When the member 22i is adjusted, the fastening surfaces 226 simultaneously fasten the mounting rods 2〇〇. Although the screw 23 is disposed along the transverse axis 2〇1, the seat tube device 2 can adjust the seat angle up and down, but the following is still missing: - the screw, 23 passes through the clamping side from 227 and the like The side surface 224 is adjusted, and the clamping side surface 227 is perpendicular to the adjusting side surface 224. Therefore, when the bicycle seat vibrates up and down, the cross section of the screw 23 must bear a great shearing force, so the screw 23 must also be large enough. It is the size of the M6 or M8) to withstand the shearing force, and the improvement in the weight reduction of the bicycle is limited, resulting in the lack of lightweighting difficulties. - <The seat g device 2 only buckles the mounting rod by adjusting the dusting force generated by the curved surface 212 and the limiting surface 228. The force of the fastening is still insufficient, resulting in a lack of fastening force. The clamping unit has more than 7C pieces and requires multiple assembly steps to be assembled, resulting in a lack of assembly. [New content] 6 M334808 Therefore, the object of the present invention is to provide a lightweight seat tube device that is easy to adjust, lightweight, easy to buckle, and easy to assemble. Therefore, the lightweight seat tube device of the present invention is suitable for use in a bicycle seat. The bicycle seat has two mounting rods, and the lightweight seat tube device comprises a tube head, a clamping unit and a fixing component. The tube head includes a support portion that defines a plurality of adjustment cambers inclined to a first axis and a support cam surface. The clamping unit includes an adjusting member and a plurality of clamping members, the adjusting member is disposed on the supporting arc surface, and forms a plurality of side inclined surfaces inclined to a second axis, and a plurality of respectively respectively abutting the mounting rods Mounting surface. The clamping members respectively abut the side slopes and each have a fastening surface that abuts the mounting rod and a limiting surface that abuts the adjustment curve. The fixing member passes through the clamping members and the side slopes along the first axis to cause the clamping members to clamp the adjusting members to respectively fasten the mounting rods to the new lightweight seat tube device. The utility model is characterized in that: the solid-state component is disposed laterally along the first axis, so that the bicycle seat can adjust the angle up and down without any segment, thereby achieving the effect of easy adjustment. ^ Second, the fixing component is laterally disposed, the bicycle seat is left and right The vibration has a smaller impulse than the conventional vibration, and the size of the fixing member can be reduced. Furthermore, the fixing element passes through the side slopes, because the fixing element is not perpendicular to the side slope, so when the bicycle seat vibrates up and down, the shearing force of the fixing element is oblique, and the fixing component is inclined The cross-sectional area of the direction is larger than the cross-sectional area of the general upright direction, so the shear force that can be withstood is also large, and the size below 7 M334808 can further reduce the size of the fixed component to the milk and w size to achieve a more lightweight effect. Third, because the side slope is inclined with the second axis, so that the buckle surface can generate a downward pressure to buckle the mounting rod, and the lower pressure generated by the upper limit surface is added to add the fastening surfaces. Sufficient to fasten the fastening force of the mounting rods. Not only the adjustment piece, but also the assembly steps
