Abstract: An improved connecting mechanism includes a rotary frame, a connecting seat, and a tightening device. The rotary frame is a substantially inverted U-shaped frame having frame wings on both sides provided with symmetrical wing holes. The connecting seat is a substantially curved structure having a front end seat and a rear end seat, the front end seat being disposed between the two frame wings and formed with a through front axial hole in a transverse direction. The front axial hole has two ends each of which is provided with a recess that is further communicated radially with a groove and a sector-like end recess. Springs are fitted into the recesses, respectively, such that a spring end at one end of each of the springs is inserted into the groove, with a spring coil extending from a spring post at the other end passing through one of the end recesses to connect to one of the frame wings. The tightening device includes a shaft passing through the two wing holes, the two springs, and the front axial hole. The shaft is connected to a knob so as to be capable of abutting against or moving away from the frame wings. And when the baffle portions contact the spring posts, the connecting seat is prevented from downward displacement, ensuring that the rear end seat maintains a certain angle.

Abstract translation: 改进的连接机构包括旋转框架，连接座和紧固装置。 旋转框架是大致倒U形框架，其两侧具有设置有对称翼形孔的框架翼。 连接座是具有前端座和后端座的基本弯曲的结构，前端座设置在两框架翼之间并且在横向方向上形成有贯穿的前轴向孔。 前轴向孔具有两个端部，每个端部设置有凹槽，该凹部进一步与凹槽和扇形端部凹槽径向连通。 弹簧分别装配到凹部中，使得每个弹簧的一端的弹簧端插入凹槽中，弹簧线圈从另一端的弹簧柱延伸穿过其中一个端部凹槽连接 到一个框架的翅膀。 紧固装置包括穿过两个翼孔，两个弹簧和前轴向孔的轴。 轴连接到旋钮，以便能够抵靠或远离框架翼离开。 并且当挡板部分接触弹簧柱时，防止连接座向下移位，确保后端座保持一定的角度。

Abstract: A bicycle includes a frame, a pedaling device, a sprocket device, a stepping device and a clutch device. The pedaling device is furnished on the frame for a rider to perform pedaling operation. The sprocket device includes an axle pivotally coupled to the frame and a front sprocket rotatably mounted on the axle. The stepping device is connected between the pedal device and the sprocket device for transmitting power from the pedal device to rotate the axle and increasing moment of force of the pedaling operation by a reciprocal stepping operation. The clutch device is furnished on the frame for performing a first position to engage with the front sprocket so that the front sprocket is driven together with the axle by the stepping device to rotate, and a second position to disengage from the front sprocket so that the front sprocket is free from driven by the stepping device.

Abstract translation: 自行车包括框架，踏板装置，链轮装置，步进装置和离合器装置。 踩踏装置设在车架上，供骑车人执行蹬踏操作。 链轮装置包括枢转地联接到框架的轴和可旋转地安装在轴上的前链轮。 步进装置连接在踏板装置和链轮装置之间，用于从踏板装置传递动力，以通过往复步进操作来旋转车轴和增加踏板操作的力矩。 离合器装置设置在框架上，用于执行与前链轮接合的第一位置，使得前链轮通过步进装置与轴一起被驱动旋转，并且第二位置与前链轮脱离，从而使 前链轮由步进装置驱动。
