[0032] By setting a clamping mechanism in this embodiment, when the user needs to process the surface of the bent drain pipe, the user can start the motor 3 in the clamping mechanism, drive the rotating rod 5 to rotate through the motor 3, drive the first bevel gear 6 to rotate through the rotating rod 5, and drive the second bevel gear 7 to rotate through the first bevel gear 6, and at the same time drive the threaded rod 8 to rotate around the bearing 18, and squeeze the internal thread inside the threaded hole 17 through the external thread on the surface of the threaded rod 8, so that the moving block 9 drives the sliding block 15, the first clamping plate 11 and the first anti-slip plate 19 to approach the center position of the drain pipe along the trajectory of the sliding groove 16 until it is clamped and fixed;

[0033] By setting the shapes of the first clamping plate 11 and the first anti-skid plate 19 to be arc-shaped, the contact area between the first clamping plate 11 and the surface of the drain pipe is increased, so that it can fit more closely when in contact with the surface of the drain pipe, and the clamping effect is better, thereby further improving the clamping effect of the clamping mechanism, and solving the problem that most of the existing clamping methods are to fix them manually using clamps and bench vises, which have high labor intensity and poor fixing effect, and are prone to shaking during the processing, thereby affecting the work efficiency.

[0034] The bottom of the moving block 9 is fixedly connected with a sliding block 15, and the inner wall of the square groove 4 is provided with a sliding groove 16 used in conjunction with the sliding block 15;

[0035] By providing the sliding block 15 and the sliding groove 16 , the sliding block 15 can be driven to move along the track of the sliding groove 16 when the moving block 9 moves, thereby limiting the moving track of the moving block 9 .

[0042] Embodiment 2:

[0043] On the basis of the first embodiment, the clamping mechanism in the first embodiment can play the role of clamping the exhaust pipe, but in the bending process, the exhaust pipe needs to be bent into the required tubular shape, which makes the shape of the exhaust pipe more complicated. It is not a straight pipe. When its surface needs to be processed, its tail will easily shake, and the user needs to manually support its tail, which will also affect its work efficiency. The fixing mechanism in the present application includes two fixing plates 12 fixedly connected to the top of the workbench 1, and two electric telescopic rods 13 are fixedly installed on one side of the fixing plate 12. The output end of the electric telescopic rod 13 is fixedly connected to the second clamping plate 14;

[0044] In this embodiment, by setting a fixing mechanism, the bent exhaust pipe can be clamped by the clamping mechanism, and at the same time, by starting the electric telescopic rod 13 in the fixing mechanism, the electric telescopic rod 13 drives the second clamping plate 14 and the second anti-slip plate 20 to move toward the tail end of the exhaust pipe until the tail end of the exhaust pipe is clamped, thereby playing a role in fixing the tail end thereof. By setting the second clamping plate 14 and the second anti-slip plate 20 to be both arc-shaped, the contact area between the second clamping plate 14 and the tail surface of the drain pipe is increased, so that the fixing effect is better, thereby further improving the fixing effect of the fixing mechanism;

[0045] The problem that the exhaust pipe needs to be bent into the required shape during the bending process causes the shape of the exhaust pipe to be more complicated. It is not a straight pipe. When its surface needs to be processed, its tail will easily shake, requiring the user to manually support its tail, which will also affect its work efficiency.

[0046] A second anti-slip plate 20 is fixedly connected to one side of the second clamping plate 14, and the second clamping plate 14 and the second anti-slip plate 20 are both arc-shaped;

[0047] By providing the second anti-skid plate 20, and the second anti-skid plate 20 and the second clamping plate 14 are both arc-shaped, the contact area between the second clamping plate 14 and the tail surface of the drain pipe can be increased, making its fixing effect better, thereby further improving the fixing effect of the fixing mechanism.

[0048] Working principle: When the user needs to process the surface of the bent drain pipe, the user can start the motor 3 in the clamping mechanism, drive the rotating rod 5 to rotate through the motor 3, drive the first bevel gear 6 to rotate through the rotating rod 5, and drive the second bevel gear 7 to rotate through the first bevel gear 6, and at the same time drive the threaded rod 8 to rotate around the bearing 18, and squeeze the internal thread inside the threaded hole 17 through the external thread on the surface of the threaded rod 8, so that the moving block 9 drives the sliding block 15, the first clamping plate 11 and the first anti-slip plate 19 to approach the center position of the drain pipe along the trajectory of the sliding groove 16 until it is clamped and fixed;

[0049] By setting the first clamping plate 11 and the first anti-slip plate 19 to be arc-shaped, the contact area between the first clamping plate 11 and the surface of the drain pipe is increased, so that the first clamping plate 11 can fit better with the surface of the drain pipe when in contact, and the clamping effect is better, thereby further improving the clamping effect of the clamping mechanism;

[0050] While the bent exhaust pipe is clamped by the clamping mechanism, the electric telescopic rod 13 in the fixing mechanism is started, and the electric telescopic rod 13 drives the second clamping plate 14 and the second anti-skid plate 20 to move toward the tail end of the exhaust pipe until the tail end of the exhaust pipe is clamped, thereby fixing the tail end thereof. By setting the second clamping plate 14 and the second anti-skid plate 20 to be both arc-shaped, the contact area between the second clamping plate 14 and the tail surface of the drain pipe is increased, so that the fixing effect is better, thereby further improving the fixing effect of the fixing mechanism.

[0051] It should be noted that the motor 3 and the electric telescopic rod 13 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. The specific composition and principle of the power supply of the motor 3 and the electric telescopic rod 13 are clear to those skilled in the art, so they are not described in detail.

[0052] 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.
