When the fixed plate 24 is squeezed, the sliding block 272 is squeezed. However, the sliding block 272 squeezes the connecting rod 271, so that the sliding block 272 is pushed by one end of the connecting rod 271 to drive the limit block 273 to slide on the inner side of the No. 1 slide slot 251, and one end of the sliding block 272 slides out a section and is inserted into the inner side of the fastening slot 121, thereby preventing the electric cabinet frame 11 from being hit and causing the battery to be smashed out of the inner side of the placement slot 12.

[0025] The movable structure 4 includes a movable track 41 fixedly installed on the inner bottom of the placement groove 12, and the outer walls on both sides of the movable track 41 are provided with rolling grooves 45, and the inner side of the rolling grooves 45 is slidably connected with a roller 42, and the outer wall of one end of the roller 42 is rotatably installed with a roller frame 43, and a placement table 44 is fixedly installed on the top of the roller frame 43, and the outer wall of the top of the placement table 44 is provided with a movable groove 442, and a movable spring 443 is fixedly installed on the bottom of the inner side of the movable groove 442, and a rubber block 441 is fixedly installed on the outer wall of the top of the placement table 44 and on the upper surface of the movable spring 443.

[0026] It should be noted that, in this embodiment, the battery is placed on the upper surface of the placement table 44, the rubber block 441 is used to cushion the battery when it is placed, and the movable spring 443 is used to quickly reset it, so as to reduce the damage to the battery when it is placed on the upper surface of the placement table 44 and when it is collided, and then the placement table 44 is pushed, so that the roller 42 installed on the roller frame 43 can roll on the inner side of the rolling groove 45, so as to facilitate the movement of the battery to the inner side of the placement groove 12.

[0027] The working principle of the present invention is as follows: by placing the battery on the upper surface of the placement table 44, using the rubber block 441 to buffer the battery when it is placed, and using the movable spring 443 to quickly reset it, so as to reduce the damage to the battery when it is placed on the upper surface of the placement table 44 and when it is hit, and then pushing the placement table 44, so that the roller 42 installed on the roller frame 43 can roll on the inner side of the rolling groove 45, so as to facilitate the movement of the battery to the inner side of the placement groove 12, After placing the battery on the upper surface of the placement table 44 inside the placement groove 12, the battery is pushed into the inner side of the placement groove 12, and the corresponding charging line is pulled out. The side plates 361 installed on both sides of the outer wall of the fixing sleeve 36 are blocked by the inclined guide plate 311 and deviated in the reverse direction, so that the side plates 361 can enter the inner side of the bottom of the guide plate 37, and then inserted into the positioning frame 38, so that the side plates 361 on both sides of the fixing sleeve 36 are inserted into the inner side of the positioning frame 38, so that the length of the charging line 33 is fixed, and then the charging interface 34 is inserted into the battery for charging. The fixing sleeve 36 enters the inner side of the positioning frame 38, and then the side plate 361 pushes the push plate 384 to move one end of the positioning frame 381 inside the movable card slot 385, so that one end of the positioning frame 381 is inserted into the card slot inside the movable card slot 385. At the same time, because the push plate 384 is moved, the fastening rod 3843 is blocked by the inclined groove 389, so that the fastening rod 3843 is rotated inside the mounting block 3842, so that it is inserted into the inner wall of the outer wall of the side plate 361 through the fastening hook 3844. The charging cable 33 is limited on the side, so that the charging cable 33 of the charging cable storage box 35 cannot be retracted, and the charging cable 33 is pulled again, so that the positioning frame 381 is separated from the inner slot of the movable slot 385, and the undulating block 386 is separated from the groove inside the movable slot 385, so that it can pull the second fixing column 387 through the pulling spring 383 to pull the pushed plate 384 back to its original position, and the fastening hook 3844 is separated from the inner side of the outer wall of the side plate 361, so that the cable can be retracted through the charging cable storage box 35. The damage caused by the collision of the electrical cabinet frame 11 causes the battery to move out of the inner side of the placement slot 12 and hit the cabinet door 21 in the opposite direction, squeezing the fixed plate 24. When the fixed plate 24 is squeezed, it squeezes the sliding block 272. However, the sliding block 272 squeezes the connecting rod 271, so that the sliding block 272 is pushed by one end of the connecting rod 271 to drive the limit block 273 to slide on the inner side of the No. 1 slide slot 251, and one end of the sliding block 272 slides out a section and is inserted into the inner side of the fastening slot 121, thereby preventing the electrical cabinet frame 11 from being hit and causing the battery to be smashed out of the inner side of the placement slot 12.
