[0016] The following further describes the present application in detail Figures 1-3 in conjunction with the attached drawings.

[0017] An embodiment of the present application discloses an automobile part correction device, including a negative pressure cover body 1. Multiple telescopic parts 2 and flaring parts 3 are sequentially arranged at the opening end of the negative pressure cover body 1, and the telescopic parts 2 and the flaring parts 3 are arranged alternately. The openings of the flaring parts 3 increase sequentially from top to bottom. A fixing mechanism is arranged between adjacent two groups of flaring parts 3. The fixing mechanism includes a plug board 7 fixedly installed on the surface of one group of flaring parts 3 and a socket 12 fixedly installed on the surface of another group of flaring parts 3. One end of the plug board 7 is fitted and inserted into the socket 12 to form a moving pair with it. A fixing bolt 11 is inserted into the socket 12, and one end of the fixing bolt 11 abuts against the surface of the plug board 7.

[0018] In this embodiment, by providing multiple flaring parts 3 with different opening sizes, the appropriate flaring part 3 can be selected according to actual usage needs. Loosen all the fixing bolts 11 on the surface of the socket 12 below the flaring part 3. During use, only need to align the appropriate flaring part 3 with the correction part and press it towards the correction part, so that the flaring part 3 fits around the correction part. During this process, after the fixing bolts 11 on the socket 12 below the flaring part 3 are loosened, the plug board 7 and the socket 12 can move relative to each other, and the telescopic part 2 between the plug board 7 and the socket 12 will contract, and adjacent flaring parts 3 will move closer and gather.

[0019] In this embodiment, the telescopic part 2 can be made of a flexible rubber material, which can ensure good sealing performance while telescoping.

[0020] Furthermore, the insertion plate 7 is of a U-shaped structure. A guide rod 8 is fixedly connected between the two ends of the insertion plate 7. A fixing plate 9 is fixedly connected to the surface of the insertion sleeve 12. The guide rod 8 passes through the fixing plate 9 and is slidably engaged therewith. A spring 10 is sleeved on the surface of the guide rod 8. One end of the spring 10 is fixedly connected to the fixing plate 9, and the other end of the spring 10 is fixedly connected to the insertion plate 7.

[0021] Furthermore, when the telescopic part 2 contracts, the two flaring parts 3 approach each other, and the spring 10 undergoes elastic deformation.

[0022] In this embodiment, by providing mechanisms such as the guide rod 8 and the spring 10, when the user aligns the flaring part 3 with the correction part and pushes it towards the correction part, the telescopic part 2 corresponding to the loosened fixing bolt 11 will contract, and the insertion plate 7 and the insertion sleeve 12 will also move relative to each other, so that the spring 10 is compressed. After use, the flaring part 3 can be separated from the correction part, and the compressed spring 10 will reset, which can drive the guide rod 8, the insertion plate 7, and the corresponding flaring part 3, etc. to reset, without the user manually resetting.

[0023] Furthermore, cushion plates 5 are provided on the lower surfaces of the flaring parts 3. The cushion plates 5 are arranged around the edges of the flaring parts 3, and sealing rubber pads 6 are fixedly connected to the lower surfaces of the cushion plates 5. The sealing rubber pads 6 can ensure that the cushion plates 5 are in contact with the part correction part to achieve the purpose of negative pressure correction.

[0024] Furthermore, a connecting pipe 4 is fixedly connected to the upper surface of the negative pressure cover 1. One end of the connecting pipe 4 is communicated with the inside of the negative pressure cover 1, and the other end of the connecting pipe 4 is connected to an external pump.

[0025] In this embodiment, during use, an external pump can be used to pump air out of the inside of the negative pressure cover 1, so as to be able to adsorb the sunken part covered by the negative pressure cover 1.

[0026] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. "Up", "down", "left", "right", etc. are only used to represent relative position relationships.
