In addition, there is a circular hole seat 12 (as shown in Figures 1 and 2) between the front and rear ends of the aforementioned two shock absorber cranks 1 near the rear wall. The connecting wall is provided with a connected cut ditch 13 (as shown in Figure 1), and the opposite ends of the cut ditch 13 are respectively fixed with a hollow receiving seat 14 (such as a cylindrical nut) and a shield that can be penetrated from the outside. The inside of the shock absorber crank 1 extends through the cutting groove 13 into the locking piece 15 for locking and positioning in the receiving seat 14; a circular seat 16 that can be finely adjusted and rotated is respectively installed in the hole seat 12 of the two shock absorber crank 1 (please Cooperate with referring to the partially exploded top view shown in Figures 3 and 4), and an eccentric corresponding eccentric hole 160 is set on the two seat bodies 16, and the outside of the seat body 16 is uniformly and densely covered with straight strip-shaped locking ribs 161, The corresponding hole seat 12 has an inner tooth-shaped inner contact surface 120 that can be locked and positioned with the locking rib 161 .

After adjustment, Then through the tightening of the locking piece 15, the cutting path of the cutting groove 13 can be pressed to control the pressure of the hole seat 12 communicating with the cutting groove 13, so that the seat body 16 in the hole seat 12 will feel the pinch. On the contrary, if the locking piece 15 is unscrewed, the cutting path of the cutting groove 13 will naturally no longer be under pressure, and the clamping force on the inner seat 16 of the hole seat 12 can be released. , so that the seat body 16 can re-use the fine-tuning element 17 to adjust the displacement angle. Then the other end of the rear shock absorber 6 is corresponding to the vehicle frame 2, and the end is pivotally connected to the first -shaped connecting seat 61 (also please refer to Fig. The both sides of 61 positions are respectively fixedly connected with two left and right side-by-side vertical support frame bodies 22 (as shown in Figure 1, 3), there is corresponding and transverse row hole 220 between two support frame bodies 22; The locking bolt 221 passes through the rows of holes 220 of the two support frame bodies 22 and

形连接座61彼此枢设连结，即可将后避震器6的前端与车架2连接固定。The connecting seats 61 are pivotally connected to each other, so that the front end of the rear shock absorber 6 and the vehicle frame 2 can be connected and fixed.

当将上列构件组装完成之后，即如图1所示，在使用上，具有以下特点：After the above components are assembled, as shown in Figure 1, in use, it has the following characteristics:

1、避震夹角可调整(请配合参阅图5、6所示)。本实用新型后避震器6之枢接座60系与固设在二避震器曲柄1孔座12内的圆形座体16偏心孔160连接，并透过微调元件17穿过偏心孔160固接同体连动，因此，当旋转微调元件17，即可同步带动后避震器6改变角度，若将避震夹角(即后避震器6与车架2间所形成之夹角)调大时(即由图5所示之夹角调至图6所示)，则灵敏度相对比较低，此时后避震器6的避震能力倾向于刚性，亦即弹跳行程相对比较小，可适合上坡行走；反之，若将避震夹角调小时(如图5所示)，则灵敏度变得相对比较高，此时后避震器6的避震能力倾向于软性，亦即弹跳行程相对比较大，可适合下坡行走。使每位选手(使用者)可视操控性能、体重、及路况来调整避震器的缓冲避震效果。1. The included angle of the shock absorber can be adjusted (please refer to Figures 5 and 6). The pivot seat 60 of the rear shock absorber 6 of the utility model is connected with the circular seat body 16 eccentric hole 160 fixed in the hole seat 12 of the crank 1 of the second shock absorber, and passes through the eccentric hole 160 through the trimming element 17 It is fixedly connected with the same body, so when the fine-tuning element 17 is rotated, the rear shock absorber 6 can be synchronously driven to change the angle. When the adjustment is large (that is, the angle shown in Figure 5 is adjusted to that shown in Figure 6), then the sensitivity is relatively low. At this time, the shock absorbing ability of the rear shock absorber 6 tends to be rigid, that is, the bounce stroke is relatively small. It can be suitable for walking uphill; on the contrary, if the included angle of the shock absorber is adjusted to a small value (as shown in Figure 5), the sensitivity becomes relatively high, and the shock absorbing ability of the rear shock absorber 6 tends to be soft at this moment, that is, The bounce stroke is relatively large, which is suitable for downhill walking. Each player (user) can adjust the buffering and shock absorbing effect of the shock absorber according to the handling performance, body weight, and road conditions.

2、避震长度可调整(请配合参阅图7、8所示)。本实用新型车架2相对于后避震器6前端的支撑架体22设有横向排孔220，因此，不同长度的避震器皆可透过调整支撑架体22上横向排孔220的相对位置，达到可置换不同避震器的功能。2. The length of the shock absorber can be adjusted (please refer to Figure 7 and 8). The vehicle frame 2 of the present utility model is provided with a horizontal row of holes 220 relative to the support frame body 22 at the front end of the rear shock absorber 6. Therefore, shock absorbers of different lengths can adjust the relative position of the horizontal row holes 220 on the support frame body 22. position to achieve the function of replacing different shock absorbers.

3、避震器曲柄1与车架2之间的角度可调整。本实用新型车架2相对避震器曲柄1的承接面20具有不同的孔位21位置(如图7、8所示)，故避震器曲柄1与车架2间具有角度调整功能，亦可藉此调整后避震器6之缓冲避震效果。3. The angle between the shock absorber crank 1 and the frame 2 can be adjusted. The vehicle frame 2 of the utility model has different hole positions 21 relative to the receiving surface 20 of the shock absorber crank 1 (as shown in Figures 7 and 8), so the angle adjustment function between the shock absorber crank 1 and the vehicle frame 2 is also provided. Can thereby adjust the buffer shock absorber effect of rear shock absorber 6.

4、避震夹角调整方便(亦请配合参阅图5、6所示)。承前述第1点所述，本实用新型只需旋松锁接件15再旋转微调元件17，即可调整避震夹角，以本实用新型实施例而言，微调元件17系采用内六角旋杆，因此，透过简单的六角扳手工具即可带动座体16旋转调整角度、外置，之后，再透过锁接件15将割沟13之割道压迫，以控制与该割沟13相通之孔座12受压，如此，孔座12内之座体16将感受到夹掣的力量，而达到牢固的定位效果，使避震角度的调整具紧密牢固性。4. It is easy to adjust the included angle of the shock absorber (please also refer to Figure 5 and 6). According to the first point above, the utility model only needs to unscrew the lock joint 15 and then rotate the fine-tuning element 17 to adjust the included angle of the shock absorber. Therefore, a simple hexagonal wrench tool can drive the base 16 to rotate, adjust the angle, and place it outside. Afterwards, the cutting groove 13 is pressed through the locking piece 15 to control the communication with the cutting groove 13. The hole seat 12 is under pressure, so that the seat body 16 in the hole seat 12 will feel the power of clamping, so as to achieve a firm positioning effect, so that the adjustment of the shock absorbing angle is tight and firm.

经由上述说明可知，本实用新型车架避震器曲柄结构之设计的确已改善传统式后叉避震器长度固定、作动夹角固定不能调整的缺失，可提供使用者可视操控性能、体重、及路况来调整避震器的缓冲避震效果，确实具有显著的增进。From the above description, it can be seen that the design of the crank structure of the frame shock absorber of the present invention has indeed improved the lack of fixed length and fixed actuation angle of the traditional rear fork shock absorber, which can provide users with visual control performance, weight Adjusting the shock absorber's cushioning and shock absorbing effect according to , and road conditions does have a significant improvement.
