[0021] A quick positioning assembly structure for a motor housing comprises a motor housing 1 and a connecting plate 2 installed at one end of the motor housing 1, a mounting end cover 3 is provided at the end of the connecting plate 2 away from the motor housing 1, and connecting holes are provided on the outer walls of the connecting plate 2 and the mounting end cover 3, characterized in that: a control gear 4 is rotatably connected to the outer wall of the mounting end cover 3, a first driven gear 5 and a second driven gear 6 are respectively meshed and connected on both sides of the control gear 4, a bolt rod 7 is fixedly connected to the inner walls of the first driven gear 5 and the second driven gear 6, a control handle 8 is fixedly connected to the outer wall of the control gear 4, the control handle 8 is used to drive the control gear 4 to rotate, and the first driven gear 5 and the second driven gear 6 can be driven to rotate synchronously by rotating the control gear 4, the first driven gear 5 and the second driven gear 6 are symmetrically distributed about the center of the control gear 4, the bolt rod 7 is rotatably connected to the connecting hole of the mounting end cover 3, and the bolt rod 7 is threadedly connected to the connecting hole of the connecting plate 2.

[0022] A first movable groove 9 and a second movable groove 10 are respectively provided on the two side walls of the bolt rod 7, a reinforcement block A11 is slidably provided on the inner wall of the first movable groove 9, and a reinforcement block B12 is slidably provided on the inner wall of the second movable groove 10, and movable plates 13 are fixedly connected to the opposite ends of the reinforcement blocks A11 and B12, and elastic elements 14 are fixedly connected to the opposite ends of the two groups of movable plates 13. When the elastic elements 14 are in a relaxed state, one end of the reinforcement blocks A11 and B12 protrude from the first movable groove 9 and the second movable groove 10 respectively, and the movable plate 13 is slidably connected to the inner wall of the bolt rod 7, and the reinforcement blocks A11 and B12 are both components made of rubber material.

[0023] Specifically, when assembling the motor housing 1, it is only necessary to align the bolt rod 7 with the connecting hole of the connecting plate 2, and then toggle the control handle 8, and use the control handle 8 to drive the control gear 4 to rotate, thereby driving the first driven gear 5 and the second driven gear 6 to rotate synchronously, and the first driven gear 5 and the second driven gear 6 drive the two groups of bolt rods to rotate synchronously.
