Specifically, the interior bottom of round platform storehouse 11 is provided with fixed frame, the outer bottom of round platform storehouse 11 is provided with circular bin gate, fixed frame with circular bin gate threaded connection is convenient for regularly open circular bin gate and overhaul the maintenance to the part of round platform storehouse 11 inside.

Specifically, the inner side wall of the main body bin 3 is symmetrically provided with electric heating plates 9, the electric heating plates 9 are electrically connected with the control panel 5, and when the device is at a low temperature, the electric heating plates 9 can be controlled by the control panel 5 to heat;

a discharge valve is arranged at the bottom of the main body bin 3, and an oil filling hole is arranged at a non-circle center position at the top of the rotary table 7;

the main part storehouse still is provided with the observation window outward, just be provided with the capacity scale mark on the observation window to in time know for operating personnel the inside surplus oil mass in main part storehouse 3, and in time supply.

The specific use method of the device comprises the following steps: as shown in fig. 1, 2, 3, 4, 5, 7 and 8, when oil is injected into the front fork of the electric vehicle, an operator manually inserts two tubes at the bottom of the front fork of the electric vehicle into the corresponding pair of insertion holes 15 until the bottom of the front fork of the electric vehicle is inserted into the placement groove 13, then controls the first motor 102 to drive the rotating shafts 106 at both sides of the circular plate 2 to rotate through the control panel 5, when one group of rotating shafts 106 at one side rotates, because the two groups of connecting gears 101 are engaged with each other, the two groups of mounting bars 107 at the same side at the bottom of the circular plate 2 rotate out from the bottom of the circular plate 2 at the same time, the oil injection head 601 is positioned right above the tube of the front fork of the electric vehicle, and then controls the second motor 121 to drive the threaded rod 124 to rotate, due to the screw action, the mounting tube 4 is forced to gradually descend, the circular plate 2 and the oil injection head 601 follow-down until the bottom end of the oil injection head 601 is inserted into the tube of the front fork of the electric vehicle, then controlling the oil delivery pump 606 to spray the oil inside the main body bin 3 into the pipe body for injecting oil to the front fork of the electric vehicle through the output end of the oil injection head 601, after the oil injection to a group of front forks of the electric vehicle is completed, controlling the oil injection head 601 to ascend, and rotating the bottom of the circular plate 2 again, then controlling the driving device 14 to drive the rotating pipe 16 to rotate by 45 degrees, rotating the turntable 7 and the mounting ring 8 by 45 degrees, moving the next pair of jacks 15 to positions right facing to the operator, gradually leaking and flowing back the redundant oil to the inside of the main body bin 3 for the front fork of the electric vehicle which is just injected with oil, when the front fork of the electric vehicle which is discharged with oil moves to the other operator, taking the front fork of the electric vehicle which is not injected with oil away by the operator and inserting the front fork of the electric vehicle which is not injected with oil into the jacks 15, so that the device can continuously inject oil to the front fork of the electric vehicle, and the mounting ring 8 is installed at the position which is not located at the center of the bottom of the center of the turntable 7, the bottom of the mounting ring 8 is uniformly provided with stirring paddles 10, when the device is used for oiling in cold weather, the electric heating plate 9 is controlled in advance to heat the oil in the main body bin 3, and in the process that the driving device 14 drives the rotating disc 7 to rotate, the stirring paddle 10 at the bottom of the mounting ring 8 can also stir the oil in the main body bin 3, so as to ensure the heating effect of the electric heating plate 9, when the device is not used, the first motor 102 is controlled to drive the four groups of mounting bars 107 to be received below the circular plate 2, then the lifting adjusting assembly 12 controls the mounting pipe 4 and the circular plate 2 to slowly descend until the four groups of oil injection heads 601 are respectively inserted into the corresponding through holes 18, and at this moment, the circular plate 2 is also very close to the top of the turntable 7, so that the occupied space of the whole device is reduced, and the circular bin door at the bottom of the circular bin 11 is opened periodically to overhaul and maintain parts in the circular bin 11.
