After the engaging portion 42 ^ large (9) in is inserted, the force of the application chain 5 is released, the outer chain piece 5 is elastically returned to the horizontal state, and the engaging portion 42 of the right connecting shaft 4 is turned into The small hole portion 113 is seated on the abutting wall 12, so that the outer end surface 421 of the engaging portion 42 of the two connecting shafts 4 is flush with the outer side surface 14 of the tab 1 after completion/assembly. As shown in Figure 8). Referring to Figures 4, 6, and 8, in summary, the present invention has the following advantages: (1) The distance dl between the positioning ends 153 of the present invention is smaller than the diameter 01 of the engaging portion 42 of the connecting shaft 4, so positioning The end 153 will position the assembled buckle 42 and the distance d2 between the limit ends 164 is smaller than the diameter 0 2 of the neck 43. Therefore, the limit end 164 is used for positioning the neck 43. The above-mentioned clamping structure is designed such that the engaging portion 42 and the neck portion 43 of the connecting shaft 4 are not easily slid back to the mounting portion 151. That is, after the shaft 4 is assembled, it is less likely to slip or fall off the joint piece 1, and the safety of use can be improved. (2) In the assembly process, when the engaging portion 42 of the connecting shaft 4 moves toward the hole portion 182 of the ninth M345062, the engaging portion 42 can be allowed to pass because the bridging surface 171 is curved outward, so that the buckle portion 42 is buckled. The bottom edge of the joint portion 42 can be smoothly moved as long as it is higher than the sliding surface 172 of the joint piece, and the bottom edge of the engaging portion 42 does not need to protrude beyond the outer side surface 14 to move to the second hole portion 182, so the shaft 4 is assembled. The length of the protrusion does not need to be too much, so the length design of the shaft 4 can be shortened, and thus can be applied to a higher-order chain for multi-step shifting, for example, ten-speed shifting. (2) After the assembly of the new type, the outer end surface 421 of the connecting shaft 4 and the outer side surface 14 of the joint piece are flush, which can avoid the lack of damage caused by the outer end surface 421 being too prominent and interfering with the derailleur when the chain is running. Therefore, the present invention can improve the safety of use. Further, the outer end surface 421 is flush with the outer side surface 14, so that the width of the connecting shaft 4 and the tab 1 after assembly is small, and thus it is also applicable to multi-step shifting. Refer to Figure 9, 1G, this new connector piece! The second preferred embodiment is substantially the same as the first preferred embodiment. The same applies to the fact that the bridging surfaces 171 of the embodiment are planar and arranged parallel to each other, so that the distance between the two bridging surfaces is fixed. . In addition, the distance between the first and second center points VIII and B of the embodiment is longer than that of the first preferred embodiment, so that the length of the fastening hole 18 is longer than that of the first preferred embodiment, and the surrounding surface In addition to including a mounting portion ΐ5ι, and a fixed (four) 152, the surrounding surface 15 further includes two elongated portions ι 54 spaced apart and connected between the mounting portion 151 and the positioning portion ι52, and the elongated portion 154 is designed as a diagonal straight surface. The distance between the two extension portions 154 is gradually reduced by the mounting portion 151 toward the clamping portion 152. This design makes the distance between the right end portions of the two elongated portions 154 large, and the assembly shaft facilitates the movement from the right end to the left side during assembly. The left end of the elongated portion 154 has a small pitch to limit the neck of the assembled shaft. In the use process after assembly of the embodiment, when the engaging portion of the connecting shaft is slid toward the 10 M345062 first hole portion 181 by an external force, since the length of the engaging hole 18 is lengthened, the buckle portion is required to be slipped. The distance of the hole portion 181 becomes long, and the engagement portion has not yet reached the first hole portion 181, and the shaft may be pulled back to the positioning portion 152 in the reverse direction. Therefore, the present embodiment also has a good anti-drop effect. Referring to Figure 11, the third preferred embodiment of the present invention is substantially identical to the second preferred embodiment, except that the bridge surface 171 of the present embodiment is of curved design. Referring to Figures 12 and 13, the bridge surface m of the fourth preferred embodiment of the present invention is vertically inclined obliquely, and the distance between the bridge faces i7i is gradually reduced from the mounting portion m toward the positioning portion 152. Therefore, the distance d3 between the first ends π is greater than the distance d4 between the second ends 174, and is less than the diameter of the fastening portion of the shaft. Therefore, the design of the bridge surface m of the embodiment can also prevent the shaft from falling off. Referring to Figures 14 and 15, the fifth preferred embodiment of the present invention is substantially the same as the preferred embodiment of the present invention, except that the sliding surface m is disposed obliquely from the mounting portion (5) toward the mounting portion (5). The positioning portion 152 is gradually inclined upward and adjacent to the outer side surface 14, thereby increasing the positioning end 153 (four) straight length production, = even if the shaft is moved up and down relative to the joint ... can be added; the positioning end 153 is blocked without facing the first A hole portion 181 slides. Referring to Figure 16, the sixth preferred embodiment of the present connector piece 1 is substantially identical to the first preferred embodiment. The difference is that the opposite ends of the inner ring surface (6) respectively fall on the positioning ends. The extensions 154 are connected to and connected to each other, and the extensions 154 are parallel designs, and the distance d5 between the extensions (9) is equal to the distance between the two positioning ends 153, which is also equal to the inner ring surface 11 M345062 163 The distance between the opposite ends, the distance d5 is slightly greater than or equal to the neck diameter of the shaft, and is smaller than the diameter of the fastening portion. Referring to FIG. 17, the seventh preferred embodiment of the present invention is substantially the same as the first embodiment of the vehicle, except that the design of the bridge recess 17 (FIG. 6) is omitted in this embodiment. The embodiment can also achieve the effect of fixing the shaft and preventing the shaft from falling off by the positioning end 153 and the limiting end 164. Referring to FIG. 18, the bridge groove 17 of the eighth preferred embodiment of the new type connector piece 1 is provided. It is defined only by the bridging surface 171, which is a beveled design that extends obliquely from the outer side 14 toward the inner side 13. The bridging surface 171 is designed such that the engaging portion of the shaft does not need to protrude too much from the outer side surface 14, that is, the month b moves to the second hole portion 182. Therefore, the embodiment can also shorten the overall width of the chain after assembly. Referring to Figures 19 and 20, the ninth preferred embodiment of the present invention is different from the second preferred embodiment (Fig. 9) in that the present embodiment omits the provision of the art bridge recess 17, and this embodiment The flange 16 has a large extension area and is engaged with two mutually parallel extension portions 154 having a top and bottom parallel extending surface 161 and an abutting surface 162, and a connecting surface 161. The inner ring surface 163 with the 162 sides of the guilty face. The inner annular surface 163 surrounds a second central point B and has two limiting end ports 64 at the ends, and the distance between the limiting ends 164 is smaller than the neck diameter of the connecting shaft. In this embodiment, the limiting end 164 is used to clamp the neck of the positioning shaft to achieve the effect of preventing the shaft from falling off. Referring to Figures 21 and 22, the new connector piece! The tenth preferred embodiment differs from the 12 M345062 of the sixth preferred embodiment (Fig. 16) in that the abutment wall 12 includes a snap portion corresponding to the small hole portion 113 and the shaft is seated. The positioning recess 121' includes a top surface and a horizontal abutment surface 122, and the seating wall 12 further includes an end surface 120 having a height between the abutting surface 122 and the outer side 14. The positioning recess 121 further has two positioning ends 123 at the ends. The distance between the positioning ends 123 is smaller than the diameter of the fastening portion of the connecting shaft, so that the mounting hole lu also has the function of positioning the connecting shaft.
