fourth gear shifting blocks 4 becomes a face, now bolt 7 is conflicted with the arc shelves limit 121 of reverse gear locking plate 12, because gear shift moving tooth 6 is subject to the radial force effect of moving back grade power and reverse gear locking plate 12 selecting shift shaft 1, the guiding surface 601 and 602 in gear shift moving tooth 6 shifting block portion is along the guiding surface 502 of five reverse gear shifting blocks 5, the guiding surface 402 of three fourth gear shifting blocks 4 slides, until the shifting block portion of gear shift moving tooth 6 enters the shifting block opening 401 of three fourth gear shifting blocks 4 completely, gear shift moving tooth 6 is again around selecting shift shaft 1 to rotate a gear shift angle, and then drive five reverse gear shifting blocks 5 get back to neutral and drive three fourth gear shifting block 4 actions, automotive transmission is made to be linked into fourth gear, just because of the existence having reverse gear locking plate 12 and these guiding surfaces, thus the oblique gear-change operation completing each gear making automotive transmission energy rapid, smooth-going, when speed changer is linked into reverse gear by neutral gear, shift shaft 1 is selected to drive gear shift moving tooth 6 to move to five reverse gear shifting block 5 directions, until be fixed on the cylinder boss 701 portions open reverse gear locking plate 12 of the bolt 7 on shifting axle 1, five reverse gear shifting blocks 5 face the shifting block breach of chain baffle plate 8, then shift shaft 1 is selected to rotate a gear shift angle, gear shift moving tooth 6 synchronous axial system also drives five reverse gear shifting block 5 actions, automotive transmission is made to enter reverse gear position, reverse gear locking plate 12 gets back to original position under the effect of torsion spring 13, now a second gear shifting block 3 and three fourth gear shifting blocks 4 are all by shifting block opening 301, 401 are connected on chain baffle plate 8, because the be fixed shelves limit 111 of support 11 of the shelves limit groove 801 on chain baffle plate 8 positioning plate is blocked, make chain baffle plate 8 cannot action, also make a second gear shifting block 3 and three fourth gear dial 4 pieces restrained cannot action, complete reverse gear operation smoothly.
