[0049] By adopting the above technical solution, the motor 103 is operated so that the two third gears 426 that are fixedly connected and mesh with each other rotate at the same time, thereby causing the rotating shaft 1 210 and the rotating shaft 3 422 to rotate at the same time.

[0050] A testing method for a multifunctional portable charging pile tester comprises the following steps:

[0051] Step 1: By turning the handle, the screw rod 2 302 is rotated, and then the protection plate 305 can be moved up and down in the cooperation between the inclined platform 303, the protection plate 305 and the plug block 304, thereby completing the protection effect of the connection port 102;

[0052] Step 2, after the motor 103 is running, the two third gears 426 rotate at the same time, and then the bevel gear 5 424 and the bevel gear 6 425 cooperate with each other, so that the rotating shaft 1 210 drives the bevel gear 2 209 and the bevel gear 1 207 to rotate, and the screw rod 1 205 rotates, and then the plug shaft 1 202 connected by the threaded rotation drives the mounting plate 203 to move, so that the awning 204 is unfolded, thereby preventing rainwater from splashing into the wiring port 102;

[0053] Step three, the motor 103 rotates to make one of the third gears 426 rotate, and then with the cooperation of the bevel gear four 423 and the bevel gear three 420, the effect of driving the rotating shaft 2 419 to rotate is achieved, so that the wedge block 404 can be moved to the outside of the storage box 401, and with the cooperation of the limit frame 408, the electric gun cable is limited to prevent the electric gun cable from shaking during the connection process.

[0054] Working principle: When the present invention is in use, when the wiring port 102 needs to be used for testing, the staff rotates the handle, thereby rotating the screw rod 302 that is fixedly connected. At this time, the inclined platform 303 that is rotatably connected to the screw rod 302 will move horizontally inside the installation box 301, so that the protective plate 305 and the plug block 304 can move upward with dampers set on both sides, thereby leaking out the wiring port 102 to complete the work of testing it. While the protective plate 305 is moving, the roller 306 can touch the control button 307, thereby achieving the effect of controlling the running motor 103. The protective plate 305 is set at the wiring port 102, thereby completing the protection effect of the wiring port 102, thereby solving the problem that dust or moisture may be mixed into the wiring port 102 during the carrying and moving process, resulting in affecting the sensitivity of the wiring port 102;

[0055] After the motor 103 is running, the two meshing third gears 426 can rotate at the same time, and then the fixedly connected rotating shaft 1 210 can be rotated under the mutual cooperation between the bevel gear 5 424 and the bevel gear 6 425, so that the fixedly connected bevel gear 2 209 drives the bevel gear 1 207 to rotate, and the fixedly connected screw rod 1 205 will rotate at this time, so that the plug shaft 1 202 connected by the outer ring thread rotation can move horizontally under the action of the top box 101, and then under the cooperation of the mounting plate 203, the effect of unfolding the awning 204 is completed, so as to achieve the effect of shielding the wiring port 102 below from rain and sun, and prevent rainwater from splashing into the wiring port 102;

[0056] At the same time, one of the third gears 426 can also drive the rotating shaft 3 422 to rotate, and then, under the cooperation of the bevel gear 423 and the bevel gear 3 420, the rotating shaft 2 419 is driven to rotate, and then, under the mutual cooperation between the two sets of vertical rods 1 402 and the vertical rods 2 403, the wedge block 404 is moved to the outside of the storage box 401. Before the wedge block 404 moves, the staff needs to open the door of the storage box 401, so that the limit frame 408 moves out of the storage box 401 and is at the same level as the wiring port 102, and by running the telescopic rod 414, the fixedly connected short plate 413 drives the cylinder 412 to move in an inclined manner. The sliding block 410 can drive the second plug-in shaft 417 to squeeze the spring 418 and move away from the limit rack 406. At this time, the support frame 407 can be pushed to move horizontally above the wedge block 404 to complete the effect of adjusting the position of the limit frame 408. After the adjustment is completed, the telescopic rod 414 can be operated in the reverse direction to make the second plug-in shaft 417 inserted into the limit rack 406 under the action of the spring 418 to complete the limit fixing effect, thereby realizing the limit operation of the plug cable, thereby solving the problem that the electric gun cable connected to the wiring port 102 will be suspended in the air during the connection between the charging plug and the wiring port 102, causing unstable shaking.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
