When in use, the fitting plate 31 on the positioning device 3 is pushed towards the fixing plate 21. During the movement, the insertion strip 32 on the fitting plate 31 enters the insertion groove 22. During this process, the elastic sheets 33 on both sides of the fitting plate 31 gradually approach the limiting block 23. During this movement, the outer wall of the limiting block 23 gradually presses the elastic sheets 33. Due to the arc - shaped setting and elastic characteristics of the elastic sheets 33, the elastic sheets 33 press towards the insertion strip 32, so that the fitting plate 31 is completely attached to the fixing plate 21. After the elastic sheets 33 pass through the bending position of the limiting block 23, they return to their original state and enter the limiting groove 24, thereby fixing the position of the fitting plate 31.

[0021] The outer wall of the first wrapping ring 34 is slidably connected to the outer wall of the tank body 1. The outer wall of the insertion strip 32 is slidably connected to the outer wall of the fixing plate 21 through the insertion groove 22. The outer wall of the elastic piece 33 is slidably connected to the outer wall of the limiting block 23.

[0022] The locking device 4 includes a positioning shell 41. A reset spring 42 is fixedly connected to the side wall inside the positioning shell 41. One end of the reset spring 42 away from the positioning shell 41 is fixedly connected to a sliding plate 43. The outer wall of the sliding plate 43 is slidably connected to the inner wall of the positioning shell 41 through the moving groove 44, and the moving groove 44 is opened in the wall of the positioning shell 41. One end of the sliding plate 43 away from the reset spring 42 is fixedly connected to an anti - detachment block 45. The outer wall of the positioning shell 41 is fixedly connected to the outer wall of the tank body 1. The side of the sliding plate 43 away from the positioning shell 41 is slidably connected to the outer wall of the tank body 1.

[0023] The connecting device 5 includes a sliding block 51. An anti - detachment groove 52 is opened in the wall of the sliding block 51. A connecting block 53 is fixedly connected to the middle of the outer wall of the sliding block 51. Second wrapping rings 54 are fixedly connected to both sides of the sliding block 51. The outer wall of the second wrapping ring 54 is in contact with the outer wall of the first wrapping ring 34. The outer wall of the second wrapping ring 54 is slidably connected to the outer wall of the tank body 1. The outer wall of the sliding block 51 is slidably connected to the outer wall of the tank body 1. The outer wall of the sliding block 51 is slidably connected to the outer wall of the anti - detachment block 45 through the anti - detachment groove 52. Push the sliding block 51 into the surface of the tank body, and move the upper surface of the sliding block 51 close to the anti - detachment block 45, and insert the anti - detachment block 45 into the anti - detachment groove 52. Then push the sliding block 51 to move upward continuously until the outer wall of the sliding block 51 can be completely attached to the tank body 1. After the sliding block 51 is completely attached to the tank body 1, slide the sliding block 51 downward so that the anti - detachment block 45 at the bottom of the tank body 1 enters the anti - detachment groove 52 at the bottom of the sliding block 51. During the process of moving the sliding block 51, since the reset spring 42 was compressed when it was squeezed before, in order to return to its original state, the reset spring 42 will return to its original state, and then push the anti - detachment block 45 on the sliding plate 43 to move along with the sliding block 51 until the anti - detachment block 45 at the bottom completely enters the anti - detachment groove 52 at the bottom of the sliding block 51. At this time, the fixing of the sliding block 52 is completed.

[0024] Working principle:

[0025] During use, the positioning device 3 and the connecting plate 2 assist in the installation of the auxiliary connecting block 53. When in use, the fitting plate 31 on the positioning device 3 is pushed towards the fixing plate 21. During the movement, the insertion strip 32 on the fitting plate 31 enters the insertion slot 22. During this process, the elastic pieces 33 on both sides of the fitting plate 31 gradually approach the limiting block 23. During this movement, the outer wall of the limiting block 23 gradually squeezes the elastic pieces 33. Due to the arc-shaped setting and elastic characteristics of the elastic pieces 33, the elastic pieces 33 press towards the insertion strip 32, causing the fitting plate 31 to completely fit to the fixing plate 21. After the elastic pieces 33 pass through the bending position of the limiting block 23, they return to their original state and enter the limiting slot 24, thereby fixing the position of the fitting plate 31. The positioning device 3 is fixed on the tank body as a connecting component of the connecting device 5, facilitating the installation process for the operator and enabling the operator to hold the carbon canister and the connecting component without having to do so simultaneously.

[0026] The locking device 4 is provided to assist the staff in connecting the connecting device 5 and the positioning device 3. After the positioning device 3 is fitted and fixed to the connecting plate, the connecting device 5 is installed. First, the locking device 4 above the tank body 1 is operated, and the sliding plate 43 is pushed to compress the return spring 42, causing the sliding plate 43 to move inside the positioning shell 41 and within the movable slot 44. At this time, the sliding block 51 is pushed to slide onto the surface of the tank body, and the upper surface of the sliding block 51 is moved close to the anti-disengagement block 45, and the anti-disengagement block 45 is inserted into the anti-disengagement groove 52. The sliding block 51 is pushed to continue moving upward until the outer wall of the sliding block 51 can completely fit to the tank body 1. After the sliding block 51 is completely fitted to the tank body 1, the sliding block 51 is lowered so that the anti-disengagement block 45 at the bottom of the tank body 1 enters the anti-disengagement groove 52 at the bottom of the sliding block 51. During the movement of the sliding block 51, since the return spring 42 was compressed when the return spring 42 was previously squeezed, in order to return to its original state, the return spring 42 will return to its original state, and then push the anti-disengagement block 45 on the sliding plate 43 to move along with the sliding block 51 until the anti-disengagement block 45 at the bottom completely enters the anti-disengagement groove 52 inside the bottom of the sliding block 51. At this time, the fixing of the sliding block 52 is completed, and then the positions of the second wrapping ring 54 and the connecting block 53 are determined. Among them, the second wrapping ring 54 and the first wrapping ring 34 are mutually fitted, and at the same time, their respective hole positions are close to each other, reducing the time for the operator to align the holes.
