Description of reference numerals
100 jacking blocks, 101 first inclined-planes, 102 through holes, 200 latch segments, 201 second inclined-planes, 202 screws, 203 boss, 300 bolts, 400 locking slots, 500 locking holes.
Detailed description of the invention
Fig. 1 shows the built-in motor catch gear of prior art, and built-in motor and bicycle bottom bracket are fixed together by screw by it, and this fixed form screw in Electrical Bicycle use procedure there will be and gets loose and drop.
Fig. 2-9 shows built-in motor catch gear of the present utility model, it comprises locking slot 400, locking hole 500, jacking block 100, latch segment 200 and lock bolt 300, wherein locking slot 400 is arranged on the outer wall of built-in motor, locking hole 500 is arranged at the inwall of Electrical Bicycle five-way, jacking block 100 is wedge shape, it has through hole 102 along its length and the first inclined-plane 101, latch segment 200 is also wedge shape, its the second inclined-plane 201 that there is threaded hole 202 along its length and coordinate with described first inclined-plane 101, latch segment 200 has boss 203, boss 203 is positioned at the one end away from jacking block 100, lock bolt 300 enters and extends in the screw 202 of latch segment 200 in the through hole 102 of jacking block 100, and be spirally connected with the screw thread of latch segment 200.
