For the aged players, because the S needs to travel through various differently set road sections, the riding speed is quite diverse, which makes it relatively high demand for the control and stability of the riding. However, the riding sensitivity and stability, as well as the cruising ability, depend on the distance between the front and rear wheels and the limbs of the front fork. When the wheelbase is changed, the handling degree will increase, so it is more suitable for more bending. Jobs, and when the track becomes longer, the degree of imprisonment will increase, so it is more suitable for 5 straight 13⁄4 speed sections. Although most of the frames are designed with appropriate track, for sensitivity and brilliance. Balanced between the two, but the singularity and the track distance can not be used to meet the diversified needs of the rider. [New content] Comprehensively, the shortcomings of the prior art, including the angle and the track system of the front fork standpipe of the conventional bicycle, are fixed, so it is not possible to adjust the angle and the track distance of the front standpipe to match the ride.

Forming an eccentric seat for inserting into the round hole and contacting the same stop surface; and a guiding member for sliding the turtle ground along the short axis of the elliptical hole to be disposed on the upper bowl, which has a circular hole for arranging the annular portion so that the upper bowl member can rotate within the guiding member; thereby, when the upper bowl member rotates, the eccentric seat will contact the stopping surface, and the guiding guide member is synchronously driven Slip 'the displacement of the upper part of the bowl in the direction of the axis of the inspection, 俾 to guide the axial position of the eccentric slot' so that it can only be along the long axis of the hole Move, and then drive the angle of the front and then the yaw. The purpose of this creation is to ensure the displacement of the upper bowl member along the short axis direction of the elliptical hole by the cooperation between the stop surface and the eccentric seat and through the uniaxial sliding of the guide member, so that the eccentric slot is only The crucible can be displaced parallel along the long axis of the elliptical hole to generate a yaw at the angle of the front and the second tube, so that the wheelbase can be changed by adjusting the angle of the vertical and the angle of the officer, so that the rider can rely on the riding condition. To make adjustments to meet the diverse needs of the rider. One of the purposes of this creation is that the Palin group and the lower Peilin group in the upper and lower bowls are each of the - arc family Weilin, so that the mosquito green can be obliquely slanted along the Qing surface. The third purpose of this creation is that the operation adjustment is quite easy, so that it can be quickly performed by rotating the upper bowl member, and it is time-saving for tJl phase #. M406569 The fourth purpose of this release is to correct the error of the angle of the head pipe of the frame by adjusting the angle of the pipe before and after the adjustment, so as to ensure the best track of the bicycle. [Embodiment] In order to facilitate the creation of the above-mentioned textbook, it is expressed in a specific embodiment. The various items in the embodiment are bribed in proportion to the size, deformation, or displacement of the description, rather than the ratio of the actual components (4), first (4). In the following description, like elements are denoted by the same reference numerals. • As shown in the first and second figures, this creation is a head group that can adjust the angle of the front fork, which mainly includes the upper bowl 10 and the lower bowl 20, respectively, to be respectively arranged on the frame head. The upper and lower ends of the tube 3 are provided, and the frame head tube 30 is provided for the front fork tube 40, and the front fork tube 4 is provided with a handle riser 50 at the top end. The upper bowl 10 includes an upper bowl seat 11, an upper bowl member 12, a guiding member 13, and an upper palin group 14 and a pressing sheet 15; the upper bowl 11 is disposed along the axis direction There is an elliptical hole, the elliptical hole has a long axis and a 'turned' hole 1H on both sides of the parallel long axis direction inner wall is divided into a curved surface 彳12, and the bottom end of the curved surface 112 is inward A top abutting portion ns is formed, and each of the curved surface 112 and the top abutting portion 113 forms a blocking surface 114. The upper housing portion 11 is respectively provided with a limiting portion 115 on both sides of the long axis direction of the elliptical hole. A receiving groove 116 is formed between the two limiting portions 115, and a fixing piece 117 is disposed on each of the limiting portions 115. The upper bowl member 12 is disposed on the upper bowl seat 11. The upper bowl member 12 has an annular portion 121. The annular portion 121 is provided with an eccentric slot 122, and the eccentric slot 122 is provided for the front and the vertical tube. 40, the eccentric slot 122 is tapered downwardly to the bottom end of the annular portion 121 to form an eccentric seat 123 for inserting into the elliptical hole 111 of the upper bowl 11 to be normally received. The abutting portion 113 is provided to be in contact with the curved surface 112. The upper bowl member 12 has at least one adjusting protrusion 124 protruding from the annular portion 121; the upper Palin group 14 is disposed in the eccentric slot 122, and the upper Palin group 14 is an arc outer ring. In the Palin, the pressing ring 15 is disposed in the upper Palin group 14 by means of the pressing ring 15 to provide a pressing force between the front fork vertical tube 4 and the upper Palin group. The sigma guiding member 13 is slidably disposed on the upper bowl buckle in the short axis direction of the elliptical hole 111, and has a circular hole 131, and the bottom portion is provided with a ring groove 132 for the upper bowl The second portion of the upper surface of the guiding member 13 is respectively abutted against each of the fixing pieces 117, and each of the fixing pieces 117 is forced by a fixing member 118. The guiding member 13 is tightly fixed, so that the guiding member 13 is fixed in the receiving groove 116 without causing falling off. The lower bowl 20 includes a lower bowl 21, a lower Palin set 22, and a lower plug 23, and the lower plug 23 is press-fitted into the bottom of the front fork stand 40, and the lower bowl 21 is sleeved on the frame. The bottom tube 3 is at the bottom end, and the lower Palin group 22 is disposed in the lower bowl 21, and the lower Palin group 22 is also a curved outer ring. After the above structure is clarified, the following is a detailed description of the action and principle of the present creation: As shown in the third figure, when the upper bowl member 12 is rotated until the adjustment projection 124 faces forward, the eccentric seat 123 is not in contact with the two. The arcuate surface 112 of the side, and the upper bowl member 12 and the guiding member 拕 are aligned with the center of the upper bowl seat, at this time, the eccentric slot 122 is offset rearwardly from the axial position of the upper bowl; As shown in the fourth figure, when the angle of the front vertical tube 40 is to be adjusted, the fixing piece 117 on the fixing piece 117 is first secreted and the snail piece above the pure hand riser is used and used. The finger pushes the adjustment protrusion 124 on the upper bowl member 12 to rotate the upper bowl member 12. When the upper bowl member 12 rotates until the adjustment projection 124 faces to the right, the eccentric seat 123 will be curved with the right side. 112 is connected to the M406569 to synchronously drive the guiding member 13 to slide to the right. When the guiding member 13 is slid by the cooperation between the stopping surface 114 and the eccentric seat 123, the upper bowl member 12 can be eliminated along the ellipse. The displacement of the hole ^ short axis direction: g, 俾 to guide the axial position of the eccentric groove 122, so that it can only along the elliptical hole 11 < (long axis · square The displacement is displaced to the axial position of the upper bowl 11. As shown in the fifth and sixth figures, the upper bowl member 12 is continuously rotated according to the above adjustment manner, 'when the upper bowl member 12 is rotated to the adjustment projection 124 When facing backward, the eccentric slot 122 will be forwardly offset from the axial position of the upper bowl 11, and when the upper bowl 12 is rotated until the adjustment projection 124 is directed to the right, the eccentric slot 122 will also And returning to the axial position of the upper bowl 11; thereby, the eccentric displacement of the eccentric slot 122 is adjusted to generate a yaw at the angle of the front tube. However, the direction of rotation of the upper bowl member 12 and The direction of the adjustment of the eccentric slot 122 is only to illustrate the action and principle of the present invention. The actual adjustment direction depends on the direction in which the eccentric seat 123 and the adjustment protrusion 124 are disposed. The direction of the long axis of the elliptical hole on the bowl 11 coincides with the direction of the axis of the frame body' and the frame head tube 30 is disposed obliquely. Therefore, if the wheel track is to be adjusted to the maximum, the bowl is closed. 12 is rotated until the adjustment bump 124 faces forward (as shown in the third figure), ie The front fork tube 40 can be driven along the upper Palin group 14 and the lower Palin group 22 for oblique yaw. After the desired angle is adjusted, the fixing members 118 are tightened to force the fixing pieces 117. The positive guide 13 is tightly fixed; otherwise, when the track is to be minimized, the upper bowl 12 is rotated until the adjustment projection 124 faces rearward (as shown in FIG. 5); The angle adjustment of the Feng Guan 4〇 allows the rider to adjust the length of the track according to the riding conditions and different riding needs to meet the diversified needs of the rider; in addition, due to the frame head tube 30 The angle is affected by the position of the bicycle before the triangle is welded to the frame head tube 30. However, since the welding position is inevitably subject to a slight error amount, the angle of the 7 lvl^Ub569 frame head tube 30 is changed, Through the angle adjustment of the front fork standpipe 4〇, the error amount of the angle of the frame head pipe 30 can be corrected to ensure the optimum track distance of the bicycle. Although the present invention is described in terms of a preferred embodiment, those skilled in the art can make various changes in the form without departing from the spirit of the present invention. The above-mentioned real pay is used to illustrate the creation of this work. It is not intended to limit the scope of this creation. Any modification or change that does not violate the spirit of this creation is the scope of patent application for this creation.
