New description: [New technical field] This creation is about a fixed structure of seat tube base, especially a locking structure that can improve the fastening effect and achieve stable support. [Prior Art] The bicycle seat tube is mainly used for the connection of the seat cushion. The seat tube is connected to the fixing rod at the bottom of the seat cushion through a fastening structure, and the seat cushion can be adjusted to adjust the inclination angle or the adjustment seat. The front and rear displacement of the pad, so the design of the fastening structure has a great influence on the fastening point and the comfort of the ride. Generally, the top seat of the seat tube is provided with a curved curved surface at the top of the seat tube, and a fastening structure is arranged between the head seat and the seat cushion, which has two clamping blocks, and the bottom of the clamping block has a curved arc-shaped card slot, so that The two clamping blocks are oppositely arranged, and the two card slots are respectively clamped on the two sides of the head seat, and the two clamping blocks are provided with a groove which can be folded out of the seat cushion to fix the positioning rod, so that the seat cushion can be assembled Provides a secure connection on the seat tube. The fastening structure is generally affixed to the upper and lower clamping type and the left and right clamping type according to the manner in which the seat cushion fixing rod is clamped. The "lightweight seat tube device" disclosed in the above-mentioned Japanese Patent No. 099213436 includes a tube head including a support portion having a support portion. a top surface and a bottom surface; • an adjustment seat disposed on the top surface and including two upwardly opening and fitting to the M M412910, the mounting groove of the mounting rods; and the two clamping blocks respectively abutting in a left and right direction In the adjusting block, each clamping block includes an inner side facing the adjusting seat, an outer side opposite to the inner side, an upper stop protruding from the inner side to the upper through slot, and a The inner side surface protrudes from a lower stop portion below the bottom surface of the support portion; a screwing member is connected to the clamping blocks, and the missing holding blocks clamp the adjusting seat via the screwing of the screwing member, and respectively Adjusting the seat buckle to engage the mounting rods; and - the elastic member, comprising two contact segments respectively facing the clamping blocks, and a connection between the contact segments and providing a force to keep the contact segments away Elastic section. The utility model relates to a seat-seat-type pipe fastening structure of a left-right clamping type, such as the "seat-clamping pipe locking device" disclosed in the Japanese Patent No. 094126976, which is characterized in that: The clamping groove of the clamping seat is supported by a clamping groove, and a shaft hole is arranged in the center of the block body, and the bottom end of the clamping block is formed with an arc-shaped card slot corresponding to the curved edge of the head of the head; The clamping jaws are arranged oppositely, so that the clamping grooves of one clamping block are respectively clamped and clamped on the two side blocks of the seat cushion supporting beam, and the bottom slots of the two clamping blocks are respectively clamped and clamped to the curved edge of the head seat. On the surface, a plug body is respectively inserted into the shaft hole of the two clamp blocks and locked, and the seat cushion and the riser tube are integrally joined; the seat cushion can be adjusted to be displaced forward and backward by loosening the plug body and After the seat cushion can be adjusted to an appropriate angle, the plug body and the clamp block can be locked to obtain an effective and stable snap connection; by the above components, the branch beam can be passed through the set of clamps The squats are directly connected to the general riser, which provides users with a practical and cost-effective 4
