Inside, when pressed down to the set position, the fixing seat (9〇) is in the state of being made on the pipe wall (501), and the effect of tightening the fixing member is achieved. Although the above-mentioned prior art fixing seat (90) has the function of pressing and fixing, when the components in the steering tube are damaged, it needs to be replaced or maintained, especially when the components mounted on the upper end of the steering tube (5〇) are replaced. Seat (10)) After being fixed in the steering tube (50), it cannot be removed from the upper mounting port, resulting in the need to remove the part from the lower end of the steering tube (5G) to the lower end of the steering tube (5). Parts mounted on the upper end are inconvenient when repairing or replacing parts. [New Content] In view of the above-mentioned shortcomings of the prior art, the present invention provides a tamper-evident bicycle steering tube fastening device, which is expected to solve the disadvantages of the prior art fixing seat being incapable of being disassembled and inconvenient to maintain. In order to achieve the above-mentioned creative purpose, the technical means used in this creation is that the detachable bicycle steering tube is tightly fixed, including: and a: a fixed seat, which is formed with a screw hole, a screw hole end and The outer expansion is formed with a pushing inclined surface, and a plurality of grooves are formed from the edge of the M 4m ^ seat to the center of the circle to form a plurality of blocks in the upper portion of the seat; 6 M343633 tightening screw 'the screw is formed around the ancient head - Extend the bevel, this part with the screw head, screw the screw hole of the seat, and make it the seat = face position is opposite. The advantage of the external expansion of the slanting (four) screw is that it is screwed to the fixing seat, and the block of the seat is externally expanded and forced to be clamped on the wall of the steering tube to obtain the effect of fixing, and the screw is loosened by the right side. , the block of the fixed seat can be taken out from the steering tube. For example, the parts inside the deflated solid can be taken out from the upper end of the south tube, so that the replacement or captive shoes can be turned to "3 maintenance. The upper part of the fixed tube is more suitable for Ma Guyi. [Embodiment] Please refer to the H. The embodiment of the pre-tightening type includes: Brother-fixing seat U0), the fixing seat (10) is one Circular block shape... Bu and small: It should be placed in the steering tube (50) inside the steering tube (10), and two opposite parallel planes (11A) are formed on the two end faces of the tamping seat (10). And (11B) 'the upper plane (11A) is provided at the center - a screw hole (12) penetrating through the fixing seat (/Ο), and a thread is formed in the hole, and the upper end of the screw hole (12) faces the plane ( 11A) forming a pushing inclined surface (13), and forming a complexing around the inclined surface (13) on the plane (11A) a hole (14), pushing against the slope (HA) and forming a plurality of grooves (15), the groove (15) is cut from the outer wall of the fixing seat (1〇) to the center, so that the fixing seat (10) The upper portion forms a plurality of protruding blocks (16) 'the depth of the hole (14) and the groove (15) is approximately close to the bottom of the fixed seat (ι) but not through the fixed seat (10)' and on the plane (11B) From the circumference, 7 M343633 is concave in a class (17), and is formed on both circles of the class (m and plane (1) A) with chamfering (1 8); tired 4 (2 0), δ hai screws (2 〇) formed with a threaded portion (2^) and a screw head (22), the screw head (22) has an outwardly extending inclined surface (23) from the joint with the threaded portion (21), and the threaded portion (21) can be combined correspondingly In the screw hole (I?), a hexagonal groove (221) is formed in the top surface of the screw head (22), and the tool rotating screw (20) is moved up and down. φ is matched with the second drawing. A hollow positioning sleeve (6〇) is disposed at the inner upper end of the steering tube (50) of the bicycle front fork, and the first implementation is performed when the component in the steering tube (50) is tightly fixed by the present invention. First, the fixing seat (10) is first placed into the steering tube (50), so that the concave portion (17) of the bottom surface of the fixing seat (1) abuts against the upper edge of the cylindrical wall of the positioning sleeve (60) Forming an abutting positioning function, the screw (20) is coupled into the screw hole (12), and when it is coupled to the fixed position screw (20), the bevel (2 3 ) will abut the screw hole (1 2) Push the upper surface of the inclined surface (13), and further insert the screw (20) into the screw hole (23) with the thread φ ° and 50 degrees, and then enter the screw hole (23) to generate an outward pushing force, due to the fixing seat ( 10) The upper part is divided by the groove (15) to form a plurality of blocks (16), so when the inclined bevel (13) is pressed by the screw (2〇), the blocks (16) are outwardly stretched and pressed tightly. It is clamped on the wall (5〇1) of the steering tube (5〇) to achieve the effect of fixing. Referring further to the third figure, a second embodiment of the present invention has a fixing base (30) and a screw, and further has an outer diameter of the screw and a corresponding screw hole (31) and a screw head (42). The top recessed hexagonal groove (421) is enlarged in size, and further 8 M343633 is provided at the center of the screw (4〇) with an axial locking hole (44), the locking hole (44) A thread is formed and penetrates the screw (40) and communicates with the hexagonal groove (421). Referring to the fourth figure, the second embodiment of the present invention is equipped with a locking rod (61) and a top cover (71) when the steering tube (50) is installed. The locking rod (61) It is a rod member, and the screw hole (44) on the screw (4〇) has an aperture matching the outer diameter of the locking rod (61), and one end of the locking rod (61) can be threaded through the screw hole (44) The top cover (71) includes a guide block (711) and a cover sheet (712), and a stud (Π3) is formed at a lower center of the guide block (711), and the stud (713) can correspond to Combined with the screw hole (ο) of the screw (4〇); in the second embodiment of the present invention, when the component in the steering tube (50) is tightly fixed, the fixing method is the same as the first type of the creation. In the embodiment, the screw (40) is combined with the screw hole (31) to force the fixing seat (10) to be tightly clamped on the pipe wall (501), and the locking bar (61) is fixed after the fixing seat (10) is fixedly fixed. Through the screw hole (44), the lower end of the locking rod (61) enters the steering tube φ (50) and is combined with the inner part of the steering tube (5G), and then the aforementioned top cover (7) is combined with the stud (7) 3) to The wire (4) of the screw holes ⑼, further studs ⑺3) combined downward to cap ⑺) against the steering tube ⑽ the nozzle, closing the steering tube (50). A ~ 々 a 丨 from the gravel (20) (40) combined with the fixed seat (10) (30), # screw (2 〇) (4 〇) generates - down pressure, and by snail,,, 糸 ( 2 0 ) ( 4 0 ) outside the slanting and wide 9, / ..., the surface (23) (43) squeezes the bevel of the fixing seat (10) (30) against (13) (32), so that the block ( ^ ^ ^ ^ 蹬(16)(34) is diverging and expanding outward, and is firmly clamped to the s-wall (501) of the steering tube (50) for a fixed purpose; 9 M343633 The second implementation of the creation In the example, the step is provided with a screw hole (44) which can be matched with the locking rod and the top cymbal (71), and can be used in the case where the locking rod (5) or other rod-shaped and reading components are required, and the top is used. The cover (7) is coupled with the screw hole (44) of the screw (10) with its stud 713) instead of the screw wall (10), so the pipe wall (5〇1) does not need to be tapped separately to be threaded with the top cover. (7)) Combination, the processing steps can be omitted; when the fixing seat (10) (10) needs to be disassembled, the screw (20) can be retracted to make the block (10) (5) of the fixing seat (10) (10) retract, and the self-steering tube can be 50) Take out the fixing seat (10) (10), and take out the upper end nozzle by the rotation = 0) It is possible to make replacement or maintenance and it is convenient to repair.
