Thrust bearings and the like may be provided at both ends of the first transmission shaft 07, the first winding shaft 08, the second transmission shaft 09, and the second winding shaft 10.

The working principle is as follows: in the initial state, the second transmission shaft 09 does not rotate, the spiral teeth 0902 are engaged with the worm gear 1001, the second transmission shaft and the worm gear 1001 do not rotate, one end of the suspension wire 1003 is connected with the suspension wire wheel 1002, and the other end of the suspension wire 1003 is connected with the lower surface of the top frame 0402 of the bracket 04, so that the lifting device stays above the bracket 04. The first stay 0802 is connected with the bottom of the engine frame 11, the second stay 0805 is connected with the top of the engine frame 11, the rocking rocker 0302 or the starting motor drives the starting chain wheel 0303 to rotate, the chain 02 starts to drive, and then drives the first transmission shaft 07 to rotate, the first bevel gear 0701 is meshed with the second bevel gear 0801 of the first winding shaft 08 to drive the first winding shaft 08 to rotate, because the first stay 0802 and the second stay 0805 are respectively fixedly connected with the first stay 0807 and the second stay 0808, the diameter of the first stay 0807 is larger than that of the second stay 0808, the rising speed of the first stay 0802 is larger than that of the second stay 0805, and then the engine frame 11 is driven to turn over while rising when the first winding shaft 08 rotates, in addition, because the two ends of the first winding shaft 08 are provided with threads, the threads are rotatably arranged on the mounting seat, so the engine frame 11 is driven to move backwards when the first winding shaft 08 rotates, when the third bevel gear 0806 is moved to the joint of the third bevel gear 0806 and the fourth bevel gear 0901, the third bevel gear 0806 is meshed with the fourth bevel gear 0901 to further drive the second transmission shaft 09 to rotate, the spiral teeth 0902 on the second transmission shaft 09 are meshed with the transmission worm gear 1001 on the second winding shaft 10, so that the second winding shaft 10 rotates, the second winding shaft 10 is provided with the suspension wire wheel 1002, one end of the suspension wire 1003 is fixedly connected to the suspension wire wheel 1002, the other end of the suspension wire 1003 is fixedly connected to the middle of the lower surface 0402 of the top frame 0402 of the support 04, the suspension wire 1003 is unfolded when the second winding shaft 10 rotates, the diameter of the suspension wire wheel 1002 is larger than that of the first stay wire wheel 0807, so that the wire unwinding speed of the suspension wire wheel 1002 is larger than that of the first stay wire 0802, the lifting device slides downwards to drive the engine frame 11 to move downwards, and the bottom surface of the engine continues to turn upwards until the engine is. Because the lifting device moves downwards, the distance between the lifting device and the starting chain wheel structure 03 is reduced, so that the chain 02 between the first transmission shaft 07 and the starting chain wheel 0303 is shortened, the chain 02 between the first transmission shaft 07 and the tensioning chain wheel 0104 and the chain 02 between the starting chain wheel 0303 and the tensioning chain wheel 0104 are extended, the two tension springs 0105 are contracted to drive the sliding block 0103 to move left, and further the tensioning chain wheel 0104 is driven to move left, so that the chain 02 is kept in a tensioning state.
