The bracket 1 is made of aluminum alloy and has good strength and corrosion resistance. The lower part of the bracket 1 is connected to the protective cover 2, the upper side of the protective cover 2 is connected to the connecting pipe 3, and one hundred and sixty nozzles 4 are connected to the connecting pipe 3. The left and right parts of the bracket 1 are both connected by threads with three groups of first fixing screws 5, each group consists of two first fixing screws 5, and the left and right parts of the bracket 1 are both rotatably connected with three groups of rotating sleeves 6, each group consists of two rotating sleeves The bracket 1 is composed of a disc 6, the first fixing screws 5 all pass through the rotating disc 6 at the same longitudinal position, the rotating disc 6 is rotatably connected to the bracket 1, and a first spring 7 is connected between the rotating disc 6 and the adjacent first fixing screw 5. The left and right parts of the bracket 1 are slidably connected with three groups of damping rods 8, each group consists of four damping rods 8, the damping rods 8 are located on the outside of the adjacent rotating disc 6, and the damping rods 8 are connected to the bracket 1 with a second spring 9, the lower part of the first fixing screw 5 is threadedly connected to the second fixing screw 10, and the second fixing screw 10 is threadedly connected to the two damping rods 8 at the same lateral position.

[0020] When the vehicle lithium battery bracket 1 needs to be installed, the device can be used, and the device can be brought to the place where the vehicle lithium battery bracket 1 needs to be installed, and the bracket 1 is brought into contact with the vehicle floor. The bracket 1 is made of aluminum alloy and has good strength and corrosion resistance. The first fixing screw 5 passes through the rotating sleeve 6, and then the first fixing screw 5 and the rotating sleeve 6 are twisted by hand to install the bracket 1 on the vehicle floor, so that the protective cover 2, the first spring 7, the damping rod 8, and the second spring 9 are installed on the vehicle floor.
