However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1 As shown, an aluminum suction tube clamping device of this application includes a first arc plate 1 and a second arc plate 2. When the first arc plate 1 and the second arc plate 2 are opposite each other, the rightmost end of the first arc plate 1 is hinged to the rightmost end of the second arc plate 2. A fixing plug 3 is fixedly connected to the end of the second arc plate 2 that is away from itself and hinged to the first arc plate 1. A lock body shell 4 is fixedly installed on the left end of the first arc plate 1, and the lock body shell 4 and the fixing plug 3 are pluggable.

[0021] The outer side of the fixed plug 3 has ratchet teeth 5 arranged linearly along the outer side contour of the fixed plug 3; the top surface of the lock body 4 is provided with a locking chamber 6 for the fixed plug 3 to enter and exit.

[0022] A cylinder 7 is installed inside the lock body shell 4. The output end of the cylinder 7 is horizontally positioned to the right, and an L-shaped baffle 8 is fixedly connected to the output end of the cylinder 7. The L-shaped baffle 8 includes a horizontally positioned horizontal section 801 fixedly connected to the output end of the cylinder 7, and an inclined section 802 that is integrally formed with the horizontal section 801 at one end away from the horizontal section 801 and the cylinder 7. In this embodiment, the angle between the inclined section 802 and the horizontal section 801 is an obtuse angle. The other end of the inclined section 802 is meshable with the ratchet teeth 5. In use, the aluminum suction tube is placed inside the first arc plate 1, and then the second arc plate 2 is rotated to close the gap between the first arc plate 2 and the first arc plate 1 to clamp the aluminum suction tube.

[0023] In this process, the cylinder 7 pushes the L-shaped baffle 8 to the right and presses down the left end of the second arc plate 2, causing the fixed plug 3 to extend into the locking chamber 6. The first arc plate 1 and the second arc plate 2 are closed by the engagement of the inclined section 802 of the L-shaped baffle 8 with the ratchet teeth 5. At the same time, the second arc plate 2 is pressed down to move the ratchet teeth 5 downward. Finally, the inclined section 802 engages with the ratchet teeth 5 at a higher point, changing the aperture between the first arc plate 1 and the second arc plate 2, thereby clamping aluminum suction tubes of different sizes.

[0024] The spring washer 9 is fixedly installed on the inner wall of the first arc-shaped plate 1, and the profile of the spring washer 9 matches the profile of the inner wall of the first arc-shaped plate 1; the spring washer 9 is arranged to avoid the extrusion and scratching of the aluminum suction pipe during clamping;

[0025] The handle 10 is fixedly connected to the outer side of the second arc-shaped plate 2, the handle 10 is U-shaped, and the outer side of the top horizontal section of the handle 10 is fixedly sleeved with the anti-skid handle 11; during use, the temperature of the first arc-shaped plate 1 and the second arc-shaped plate 2 close to the aluminum suction pipe is high due to the high temperature of the aluminum suction pipe during use, and therefore the handle 10 can avoid the staff from being scalded when the second arc-shaped plate 2 is moved;

[0026] The base 13 is fixedly connected to the outer side of the first arc-shaped plate 1 through the U-shaped plate 12, and the bottom surface of the lock body shell 4 is fixedly connected to the left side of the top surface of the base 13; the T-shaped frame 14 is fixedly installed on the inner wall of the bottom surface of the lock body shell 4, and the top surface of the T-shaped frame 14 is fixedly connected to the bottom surface of the air cylinder 7.
