[Prior Art] The conventional coupling has a main power connection end and a secondary power connection end, the main power connection end is connected to the engine output shaft with the south torque, and the sub power connection end is connected to the driven shaft of the driven part. Thereby, the power of the engine output shaft is transmitted to the driven shaft. Usually, in order to ensure that the power of the engine output shaft can be reliably transmitted to the driven shaft, a keyway is respectively arranged on the secondary power connecting end and the driven shaft, and the key and the keyway are used together to avoid the secondary power connecting end and the slave when the power transmission occurs. The sliding between the moving shafts affects the efficiency of power transmission. However, it is usually limited by the processing precision. 'The gap between the keyway and the key will be generated, so that the power cannot be transmitted exactly' and the key separated from the keyway when the shaft is rotating will produce relative sliding in the keyway, which makes the power more powerful. The transfer is affected. In addition, the provision of the pin groove and the slot key on the secondary power connection end and the driven shaft are another common design. However, the processing of the bolt groove and the bolt key is difficult to achieve a fairly accurate degree, so that a gap is easily generated between them, so that when the bolt groove and the bolt key are combined, the actual power transmission cannot achieve the actual power transmission.

The fixing portions 122 are configured to fix the first coupling 11 and the second coupling 13. A portion of the fixing portion 122 for fixing the first coupling 11 and a fixing portion 122 for fixing the second coupling 13 are alternately disposed, wherein each of the fixing portions 122 for fixing the first coupling 11 is provided. Correspondingly, the surface 111 of the first coupling 11 is provided with a fixing hole 114 in a direction along the central axis 16. After the fixing member 17 passes through the corresponding through hole 1221 and is fastened to the corresponding -6 - 1354073 fixing hole 114, the fixing between the elastic member 12 and the first coupling u is completed, as shown in FIG. The adjacent fixing portions 122 are connected by a connecting portion 123 to form a receiving opening 124. Each of the connecting portions 123 is substantially in the shape of a long strip having a smaller cross section than the connecting surface 1223 of the two connecting end faces thereof, so that the fixing portion 122 can securely fix the first coupling member and the second coupling member 13. Moreover, since the cross section of the connecting portion 123 is thin, the elastic member 12 is made more elastic. In the present embodiment, there are three fixing portions 122 for fixing the first coupling device ,, and three fixing portions 122 for fixing the second coupling device 13, and the fixing portions 122 are connecting portions. After the 123 is coupled, the elastic member 12 assumes a hexagonal shape. Referring to Figures 3 and 4, each of the fixing portions 122 for fixing the second coupling 13 is provided with a uniform through hole 1222 which penetrates the corresponding fixing portion 122 in the radial direction. The body 131 of the second coupling 13 is disposed at a position penetrating the through hole 222 in the radial direction, and is provided with a fixing hole 1311. When the body 131 of the elastic member 12 is received in the opening 124, the second coupling 13 is fixed to the elastic member 12 after the fixing member 17 passes through the through hole 1222 and is fastened to the corresponding fixing hole 1311. on. In the embodiment of the present invention, the elastic member 12 may be made of a rubber material, but is not limited thereto, and other suitable elastic materials may be used for the elastic member 12. Referring to Fig. 3, the second coupling 13 includes a body 131, a shaft connecting portion 132, and a sleeve 133. The body 131 has a cylindrical shape, and a surface 1312 is formed at one end thereof, and the shaft connecting portion 132 is protruded from the surface 13 12 of the body 131. Referring to FIG. 4, the shaft connecting portion 132 is for connecting one of the shaft end portions 141' of the power output shaft 14. Therefore, when the power input shaft 15 is connected to the shaft end portion 112 of the 1354073, the first coupling shaft can be a power wheel input shaft. 15 is rotated, and the elastic member 12 drives the second coupling 13 and rotates the power output shaft ^. Referring to FIG. 3 and FIG. 5, the power output shaft 14 is a bolting shaft, and the second coupling shaft The shaft connecting portion 132 of the device 13 is constructed to fit the bolt shaft (power take-off shaft 14). On the shaft connecting portion 132, there is an inner surface defining a slotted hole 1323 in which the power take-off shaft 14 is received. The inner surface of the shaft connecting portion 132 is provided with a bolt groove 1322 fitted in one of the power wheel output shafts 14 so that the power output shaft 14 does not slide relative to the shaft connecting portion 132. In the embodiment of the present invention, the inner pin slot 1322 may include a plurality of pin teeth, but is not limited thereto, and the pin groove is circumferentially disposed on the inner surface. Each of the pin teeth extends toward the central axis 16. The pin teeth may have an involute tooth shape, but are not limited thereto. Referring to FIG. 5, which is an end view of the shaft connecting portion 132 of FIG. 3, the inner bolt groove 1322 can have 14 bolt teeth; and as shown in FIG. 6, it is also FIG. The end face diagram of the shaft connecting portion 132 can include 21 bolt teeth. Referring to FIGS. 5 to 7, the shaft connecting portion 132 further includes an end surface 1324 and an outer tapered surface 1325. The end surface 1324 Located at the extreme end of the shaft connecting portion 132, it is connected to the inner surface and the outer tapered surface 13 2 5 . The outer tapered surface 13 2 5 is a sloped surface having an inner diameter that gradually increases from the end surface 1324 toward the body 131. In the present embodiment, the taper angle of the outer tapered surface 1325 is about 2.86 degrees' or Morse taper #2. A plurality of slits 1326 may be formed on the shaft connecting portion 132 to form the plurality of slits 1326. The slits 1326 equally divide the shaft connecting portion -8 - 1354073 132 into a plurality of portions, and each cut The grooves 1326 extend from the end face 1324 to the surface 1312 of the body 131 such that the end face 1324 is also substantially equally divided into portions. Referring to FIGS. 5 and 6, in the present embodiment, the inner pin slot 1322 includes a plurality of pin teeth '' and each slot 1326 is formed on the tooth top surface 1328. This avoids the formation of the slot 1326. The reduction of the pin teeth causes the structural strength of the inner detection slot 1322. A plurality of slots 1326 are formed in the shaft connecting portion 132, i.e., the shaft connecting portion 132 is divided into substantially equivalent portions that are independently movable. In general, as described in the [Prior Art] section, the gap between the pin groove and the pin groove is due to the machining accuracy, and since the entire shaft connection portion without the groove is relatively rigid, it is not easy to deform even if pressure is applied. That is, the bolt groove sleeve of the shaft connecting portion cannot be attached to the bolt shaft portion of the power input shaft, and the gap cannot be eliminated. However, in the present invention, the shaft connecting portion 13 2 is cut into a plurality of movable portions by the slits 1326, except that the portions are relatively easily biased to be deformed to be in close contact with the shaft end portion 141 of the power output shaft 14. In addition, the individual parts can be individually adjusted according to the size of the gap to be adjusted, so that the gap between the inner pin groove 1322 and the shaft end portion 141 can be effectively controlled to be more effectively eliminated. In general, the slits 1326 may have a width of any size as long as each divided portion of the shaft connecting portion 132 can be effectively pressed against the shaft end portion 141' and the gap between them is eliminated to be a suitable width. However, in this embodiment, the width of the slot 1326 is substantially less than the width of the top surface 1328 between the inter-groove teeth. In particular, the two adjacent slots 1326 may include a plurality of pin teeth. In an embodiment, the inner slot 1322 includes 14 bolt teeth, and the adjacent slots 1326 may include 2 bolting teeth; and in another embodiment 9-1357443, in the case where the inner bolt groove 1322 includes 21 bolt teeth, the adjacent slots 1326 may include 3 bolt teeth, so that Allow the shaft connection! 32 more reliably eliminates the gap between the shaft end portion 141 and the mechanical strength of each divided portion of the shaft connecting portion 132. Referring to FIGS. 7-9, the second coupling 13 further includes a sleeve 133. The sleeve 133 includes an inner edge surface 1331'. The inner edge surface 1331 defines an inner hole 1333' in which the inner hole 1333 and the shaft The connecting portion 132 is in a shrink fit such that the shaft connecting portion 132 can be tightened to be tight with the shaft end portion 141. In the present embodiment, the inner edge surface 丨331 has a taper that matches the taper of the shaft connecting portion 132, and the taper angle of the inner edge surface 1331 is about 2,86 degrees or the taper of the No. 2 (Morse taper #2) . By the taper fit between the inner edge surface 1331 and the shaft connecting portion 132, the respective divided portions of the shaft connecting portion 132 can be effectively pressed to the inside, and the bolt teeth of the shaft connecting portion 132 can be coupled with the power output shaft 14 The pin grooves on the shaft end portion 141 are tightly coupled. The outer tapered surface 1325 of the shaft connecting portion 132 is further provided with a locking portion 1327, and the sleeve portion 33 is correspondingly provided with a locking portion 332, and the locking portion U27 is disposed on the outer tapered surface. And close to the surface of the body ΐ3ι. Where the locking portion 1332 is constructed to be locked to the locking portion 1327. In the embodiment, the locking portion 1327 is a male thread, and the locking portion 1332 is a female thread that can rotate the sleeve 133 by using a ratio of the female, the 11⁄4 thread and the inner edge surface 丨33 i and the outer tapered surface 325. In a manner, the respective knives of the shaft connecting portion 132 are pressed to the inside, so that the bolt teeth of the shaft connecting portion 132 can be tightly coupled with the bolt grooves on the shaft end portion 141 of the power output shaft 14, and After the sleeve 133 is locked in position, the sleeve 133 can also be firmly fixed. In particular, 10. 1354.073, as shown in FIG. 7, each slot 1326 extends from the end face 1324 to the surface 13 12 of the body 131 and extends through a male thread formed on the outer tapered surface 1325. The technical content and technical features are disclosed above, but those skilled in the art can still make various substitutions and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention should be construed as not limited by the scope of the invention, and the invention should be
