[0016] 1. The utility model provides a damper between the workbench and the base, and the damper can achieve good shock absorption of the workbench during operation to avoid vibration of the workbench during cutting. At the same time, when vibration occurs, the vibration is transmitted to the lifting plate through the connecting column, so that the lifting plate moves up and down inside the buffer cavity. Since the buffer cavity is filled with shock-absorbing silicone oil, good buffering can be achieved through the compression elasticity of the shock-absorbing silicone oil, thereby further reducing the amplitude of vibration and achieving a good shock absorption effect.

[0017] 2. The utility model opens a dust collecting chamber inside the base. When the cutting mechanism cuts the pipe, the vacuum machine is started, which will generate negative pressure in the dust collecting chamber. The dust collecting chamber will generate suction through the connection of the air inlet pipe. The dust generated by the cutting will enter the dust collecting chamber through the through hole, and then the dust will be transported to the inside of the dust collecting chamber through the air inlet pipe. The dust can be filtered through the filter net, thereby reducing the escape of dust during cutting, achieving good dust collection, and avoiding harm to the health of the user.

[0018] 3. The utility model is provided with an electric slide rail at the upper end of the workbench, and a lower fixed block and an upper fixed block are provided at the output end of the electric slide rail.

[0035] See also Figure 1 and Figure 3 Two sealing doors 3 are movably installed at the front end of the base 1. The setting of the sealing doors 3 is convenient for users to clean the dust regularly.

[0036] Working principle: When in use, start the second electric telescopic rod 10 to separate the upper fixed block 9 and the lower fixed block 8, put the pipe into the fixed groove at the upper end of the lower fixed block 8, start the second electric telescopic rod 10 to make the lower fixed block 8 move downward, so that the placed pipe can be clamped and fixed, start the electric slide rail 7 to make its movable end drive the pipe to move, so that one end of the pipe passes through one side of the workbench 2 and moves to the bottom of the cutting mechanism 6, start the first electric telescopic rod 5 to make the cutting mechanism 6 move downward, and then start the cutting mechanism 6 to cut the pipe. The cut pipe will slide into the interior of the collection box 4 through the slope due to gravity, and dust will be generated during cutting. Start the suction machine 21, and the suction machine 21 will extract the air inside the dust collecting chamber 20 through the outlet pipe 22, thereby generating negative pressure. The connection through the air inlet pipe 19 will generate suction in the dust suction chamber 17, and the dust generated by cutting will enter the interior of the dust suction chamber 17 through the through hole 18. The through hole 18 can prevent larger impurities from falling into the dust suction chamber 17, and the dust will pass through The air inlet pipe 19 enters the interior of the dust collecting chamber 20, and the dust can be filtered through the filter 23 to prevent the dust from entering the suction machine 21 and causing it to malfunction, so that the dust can be left in the dust collecting chamber 20. The user can clean the dust by opening the sealing door 3, which is convenient to use. The workbench 2 will vibrate during cutting, and the rubber column 11 can buffer the vibration to a certain extent. The damper 12 can effectively reduce the vibration amplitude of the workbench 2, and when the workbench 2 rotates, the vibration will be transmitted to the lifting plate 15 through the connecting column 16, so that the lifting plate 15 can be lifted up and down in the buffer chamber 13. The guide rod 14 can limit the direction of the lifting plate 15 to prevent the lifting plate 15 from being offset. Since the buffer chamber 13 is filled with shock-absorbing silicone oil, the lifting plate 15 can be buffered by the compression elasticity of the shock-absorbing silicone oil, and then the shock absorption of the workbench 2 can be achieved through the connecting column 16, which can further reduce the vibration amplitude of the workbench 2 and achieve a good shock absorption effect.
