The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0044] In the specific use of this embodiment, when it is necessary to cut the pipe fitting 3, firstly, the pipe fitting 3 is placed inside the placement groove on the top surface of the placement plate 2, and then the turntable 88 is rotated by the lever 89. The rotation of the turntable 88 drives the connecting column 87 coaxially fixed thereto to rotate, and the rotation of the connecting column 87 drives the rotating column 82 coaxially fixed thereto on the same side to rotate, and the rotation of the rotating column 82 drives the two-way screw rod 83 coaxially fixed thereto to rotate, and the rotation of the two-way screw rod 83 drives the two moving rods 84 threadedly connected thereto to approach each other, and the moving rod 84 moves under the guidance of the slider 85 on the same side and the sliding groove on the top surface of the working plate 1, and the movement of the moving rod 84 drives the clamping plate 86 fixed thereto to move, and when the surface of one side of the clamping plate 86 close to the pipe fitting 3 is in close contact with the circumferential outer wall of the pipe fitting 3, the rotation of the lever 89 is stopped;

[0045] Subsequently, the water supply pipe of the external water supply device is tightly connected to the water inlet end of the water pump 73, and the electric push rod 92, the cutting motor 96, the water pump 73 and the cooling motor 79 are started through the external PLC. The output shaft of the cutting motor 96 rotates to drive the roller 95 coaxially connected thereto to rotate, and the rotation of the roller 95 drives the circular saw blade 97 coaxially fixed thereto to rotate. At the same time, the piston rod movement of the electric push rod 92 drives the mounting block 93 fixed thereto through the gasket 94 to move downward. The movement of the mounting block 93 can indirectly drive the circular saw blade 97 to move downward. During the downward movement of the circular saw blade 97, the pipe fitting 3 can be cut. At the same time, after the water pump 73 is started, the water in the external water supply device is transported from its water supply pipe to the inside of the water inlet pipe 74 and enters the inlet The water in the water pipe 74 then enters the water box 71 and flows into the water outlet pipe 75. The water in the water outlet pipe 75 then enters the water spray plate 76 and sprays out from a plurality of water outlet holes on the outer wall thereof. At the same time, the output shaft of the cooling motor 79 rotates to drive the rotating shaft 710 coaxially connected thereto to rotate. The rotating shaft 710 rotates to drive the driving gear 78 coaxially fixed thereto to rotate. The driving gear 78 rotates to drive the driven gear 77 meshing therewith to rotate. The driven gear 77 rotates to drive the water outlet pipe 75 coaxially fixed thereto to rotate. The rotating water outlet pipe 75 rotates to drive the water spray plate 76 fixed thereto to rotate. Thus, the water spray plate 76 can spray water while rotating, thereby cooling the cut end face of the pipe 3 and the circular saw blade 97.

[0046] When the cutting is completed, the cutting motor 96, the water pump 73 and the cooling motor 79 are turned off through the external PLC and the piston rod of the electric push rod 92 is controlled to retract. The movement of the piston rod of the electric push rod 92 drives the circular saw blade 97 to rise. When the circular saw blade 97 moves to the initial position, the electric push rod 92 is turned off through the external PLC.
