[0033] Embodiment 2:

[0034] On the basis of the first embodiment, in this embodiment, the driving shaft 312 drives the driving pulley 45 to rotate together, so that the driving pulley 45 drives the dust suction fan blade 44 to rotate together through the transmission belt 461, the driven rotation and the driven shaft 47, so that negative pressure is generated inside the dust suction box 42 to suck in most of the dust, thereby preventing the dust generated during the cutting process from floating around without being dealt with in time and damaging the respiratory health of the staff.

[0035] The dust collection assembly 4 includes a dust collection box 42, dust collection blades 44, a driving pulley 45, a driven pulley 46, a driven shaft 47 and a stabilizing bracket 48.

[0036] A driving pulley 45 is arranged on the left side of the annular side of the driving shaft 312, and a transmission belt 461 is arranged between the driving pulley 45 and the driven pulley 46. The driving pulley 45 drives the driven pulley 46 to rotate through the transmission belt 461. A protective mesh plate 41 is installed on the right end face of the dust box 42. The protective mesh plate 41 is a detachable structure. The detachable protective mesh plate 41 not only protects the right end face of the dust box 42, but also facilitates disassembly and cleaning at a later time. A discharge hose 43 is connected to the left end of the dust box 42, and the outlet of the discharge hose 43 is connected to the external filter. The dust collector inlet is connected, and the discharge hose 43 is made of a corrugated hose. The discharge hose 43 made of a corrugated hose will not only guide the dust discharged from the dust box 42 to the outside filter dust collector for filtration, but also has many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance, etc. An annular baffle 481 is installed on the left end face of the stabilizing bracket 48, and a limiting ring 471 is set on the annular side of the driven shaft 47. The annular baffle 481 and the limiting ring 471 prevent the driven shaft 47 from displacement or shaking during rotation.

[0037] Working principle: During the process of electric power design and construction, the electric power pipe body 7 needs to be cut to the required length. The staff first places the electric power pipe body 7 to be cut horizontally on the upper end surface of the cutting table 1. During this process, the electric power pipe body 7 needs to be leaned against the front end surface of the rear baffle 36, and the part of the electric power pipe body 7 to be cut is aligned directly below the cutting blade 31 and remains motionless. Then another staff member controls the two sets of second electric telescopic rods 38 to extend through the control panel, so that the two sets of second electric telescopic rods 38 drive the two sets of positioning push plates 37 to move backward to the electric power. The tube body 7 is clamped and fixed to prevent the electric tube body 7 from being displaced during the cutting process; then the driving motor 311 is started through the control panel and the first electric telescopic rod 35 is controlled to extend. During this process, the driving motor 311 drives the cutting blade 31 to rotate through the driving shaft 312, and the first electric telescopic rod 35 drives the support plate 32 to move downward through the connecting frame 33, so that the support plate 32 drives the cutting blade 31 to move downward together through the driving motor 311 and the driving shaft 312, so that the rotating cutting blade 31 moves downward to the electric The power pipe body 7 is cut off. When the power pipe body 7 is cut off, the first electric telescopic rod 35 is controlled to retract, so that the support plate 32 drives the cutting blade 31 to move upward to the original position through the driving motor 311 and the driving shaft 312. At this time, the two sets of second electric telescopic rods 38 are controlled to retract, so that the two sets of second electric telescopic rods 38 can drive the two sets of positioning push plates 37 to move forward, so that the staff can take away the cut power pipe body 7; at the same time, the driving shaft 312 will drive the driving pulley 45 to rotate together, so that the driving pulley 45 passes The transmission belt 461 drives the driven rotation, and the driven pulley 46 will drive the dust suction fan blades 44 to rotate together through the driven shaft 47. At this time, negative pressure will be generated inside the dust suction box 42 and most of the dust on the right side will be sucked in through the protective mesh plate 41. The sucked dust will be blown to the outside through the discharge hose 43 to the inside of the filter dust collector for filtration, thereby preventing the dust generated during the cutting process from floating around and not being dealt with in time, which will damage the respiratory health of the staff. When the power pipe body 7 has been completely cut, the staff only needs to turn off the drive motor 311.

[0038] 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.
