[0026] A reset part for automobiles includes a reset spring for automobiles and an upper limit mechanism 2, wherein the upper limit mechanism 2 includes a sleeve 201 sleeved inside a spring body 101, a plurality of strip-shaped limit openings 202 are provided in an annular array at the bottom of the sleeve 201, a second curved portion 103 is inserted into the strip-shaped limit openings 202, and the strip-shaped limit openings 202 are provided for the second curved portion 103 to be inserted, thereby limiting the second curved portion 103. A limit ring 203 is fixedly connected to the outer side of the sleeve 201, and the limit ring 203 is located above the second curved portion 103. The setting of the limit ring 203 can further block and limit the second curved portion 103. The top of the limiting ring 203 is fixedly connected with a plurality of reinforcing ribs 204 in a circular array, and each group of reinforcing ribs 204 is fixedly connected to the sleeve 201. The setting of the reinforcing ribs 204 can further connect and fix the sleeve 201 and the limiting ring 203, thereby improving the connection stability between the limiting ring 203 and the sleeve 201.

[0027] The top of the sleeve 201 is fixedly connected with a plurality of connecting columns 205 in an annular array, and the top of each group of connecting columns 205 is fixedly connected with a top plate 206, and the top of the top plate 206 is fixedly connected with a first hexagonal shaft 207, and the first hexagonal shaft 207 is used to be inserted into the corresponding shaft hole on the handle of the roof handle, so that when the roof handle rotates, the first hexagonal shaft 207 and the sleeve 201 can be driven to rotate accordingly, and when the sleeve 201 rotates, the second curved portion 103 can be driven to rotate accordingly, so that the spring body 101 is twisted and deformed. The lower limit mechanism 3 includes a base 301 arranged below the sleeve 201, and the top of the base 301 is provided with a plurality of slots 303 in an annular array, and the third curved portion 104 is inserted into the inside of the slots 303, and the arrangement of the slots 303 can limit the third curved portion 104.
