[0022] A car exhaust pipe hook, such as Figure 1 , 2 As shown, the exhaust bin 1 is characterized in that: an exhaust pipe 101 is fixed at one end of the exhaust bin 1, a first hook 102 is provided on the outer surface of the exhaust pipe 101, a second support column 306 is provided on the top of the first hook 102, a conical groove 201 is fixed inside the second support column 306, a first spring 203 is fixed inside the conical groove 201, a circular groove 204 is fixed at the bottom of the second support column 306, a conical column 2 is fixed at the bottom of the first spring 203, and the conical column 2 passes through the circular groove 204, and a baffle 202 is fixed on the top of the second support column 306;

[0023] The rebound of the first spring 203 will pull the conical column 2, and when the conical column 2 is pulled, it drives the first hook 102 to move upward.

[0024] like Figure 2 As shown, a first support column 301 is fixed to the top of the baffle 202, two groups of first grooves 304 are fixed to the outer surface of the first support column 301, and a second support plate 308 is fixed to the top of the first support column 301;

[0025] The conical column 2 slides inside the movable conical groove 201, and the circular groove 204 restricts the conical column 2 to prevent the conical column 2 from falling.

[0026] It can be understood that the first hook 102 is aligned with the exhaust pipe 101. When the first hook 102 is aligned, the first hook 102 is released. At this time, the first spring 203 will pull the conical column 2 due to its rebound. When the conical column 2 is pulled, it drives the first hook 102 to move upward. When the first hook 102 moves upward, the exhaust pipe 101 is suspended.

[0027] like Figure 3 , 4 As shown, the outer surface of the first support column 301 is slidably connected with a first sliding sleeve 305, the two sides of the first sliding sleeve 305 are fixed with support rods 3, the top of the support rod 3 is fixed with a first support plate 303, and the first support plate 303 is provided with a first screw 302 inside;

[0028] When the first sliding sleeve 305 is fixed, the first screw 302 is rotated, and the first screw 302 drives the first support plate 303 to be fixed. When the first support plate 303 is fixed, the second support plate 308 is fixed.

[0029] like Figure 4 As shown, the outer surface of the second support column 306 is slidably connected with the second sliding sleeve 4, the outer surface of the second sliding sleeve 4 is fixed with a third groove 405, the inner wall of the second sliding sleeve 4 is fixed with a second spring 403, one side of the second sliding sleeve 4 is fixed with a fixing block 402, the outer surface of the fixing block 402 is fixed with the second groove 404, the second spring 403 is provided with a second screw 307, and the second screw 307 passes through the second groove 404 and the third groove 405, and the top of the fixing block 402 is fixed with a second hook 401;

[0030] The second sliding sleeve 4 is rotated, and the rotation of the second sliding sleeve 4 drives the second hook 401 .

[0031] It can be explained that when the second hook 401 rotates to correspond to the first hook 102, the second sleeve 4 is fixed. When the second sleeve 4 is fixed, it drives the second hook 401 to be fixed. At this time, if the exhaust pipe 101 falls out from the top of the first hook 102, the exhaust pipe 101 will be restricted due to the action of the second hook 401 to prevent the exhaust pipe 101 from falling out.

[0032] Working principle: Slide the first sliding sleeve 305, and when the first sliding sleeve 305 slides, it drives the support rod 3 and the second screw 307 to slide. When the second screw 307 slides, it aligns with the first group of grooves 304 at the bottom. When aligned, rotate the second screw 307 to fix the first sliding sleeve 305. When the first sliding sleeve 305 is fixed, rotate the first screw 302. The first screw 302 drives the first support plate 303 to be fixed. When the first support plate 303 is fixed, fix the second support plate 308. If the second support plate 308 releases the first support column 301 and slides down, the first groove 304 at the bottom slides down. At this time, the second screw 307 clamps the first groove 304 at the top to prevent the first support column 301 from falling.

[0033] When the first support column 301 is fixed, the first hook 102 will be pulled to align with the exhaust pipe 101. When the first hook 102 is aligned, the first hook 102 will be released. At this time, the conical column 2 will be pulled due to the rebound of the first spring 203. When the conical column 2 is pulled, the first hook 102 will be driven to move upward. When the first hook 102 moves upward, the exhaust pipe 101 will be suspended. If the first spring 203 is damaged due to long-term use, when the movable conical column 2 moves downward without the pulling force of the first spring 203, the conical column 2 slides inside the movable conical groove 201, and the circular groove 204 is aligned with the conical column 201. The restriction of the conical column 2 prevents the conical column 2 from falling, and the conical column 2 holds the first hook 102 to prevent it from falling, and rotates the second sleeve 4. The rotation of the second sleeve 4 drives the second hook 401. When the second hook 401 rotates and corresponds to the first hook 102, the second sleeve 4 is fixed. When the second sleeve 4 is fixed, it drives the second hook 401 to be fixed. At this time, if the exhaust pipe 101 falls out from the top of the first hook 102, the exhaust pipe 101 will be restricted due to the action of the second hook 401 to prevent the exhaust pipe 101 from falling out.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
