In order to put the hand-held cutting device on site, the right-angle part is cut in a manner of reserving 1-2cm when the outer frame is cut in advance, the 45-degree angle part is cut on site, and after the outer frame is cut on site, a color pen is used for marking the boundary line to be cut on the side to be cut of the outer frame according to the actual size of the site, as shown in fig. 8, assuming that the outer frame is a, when the right-angle part is cut, the outer frame is firstly placed on the horizontal supporting surface of the supporting plate 330, the outer frame is attached to the supporting clamping plate 310, the outer frame is capable of moving according to the fixed direction under the constraint of the supporting clamping plate 310 and the horizontal supporting surface, the rolling body 400 is not attached to the first side plate 100 and the second side plate 200 because the rolling body 400 needs to move in the channel, so that a space is reserved for connecting the outer frame 412, and if the outer frame is attached to the second side plate 200, the side to be cut cannot be completely within the length range of the rolling body 400, and therefore part of the outer frame is not cut, but the outer frame is supported in advance by the supporting clamping plate 310.
When the outer frame a is moved, the boundary line to be cut is overlapped with the observation line formed by the observation plate 110, the telescopic rod 3211 works after the overlapping, the telescopic end of the telescopic rod pushes the extrusion clamping plate 322 to be close to the outer frame a until the telescopic end is contacted with the outer frame a, the outer frame a is clamped and fixed by the supporting clamping plate 310, the outer frame a is fixed in a channel at this time, and the other end of the outer frame a is grounded (in the state shown in fig. 8), so that the cutting is more convenient for an installer, and particularly, the rolling cutter 400 is driven in the channel by the handheld handle 411 to move along the movement starting point of the fixed track to the movement ending point, thereby forming the cutting boundary line a, cutting off the redundant part of the side to be cut of the outer frame a, achieving the purpose of trimming, and the trimmed plane is smoother and less in many burrs.
As shown in fig. 9, when cutting the 45 ° corner, the outer frame a is placed on the 45 ° supporting surface of the supporting plate 330, the outer frame a is attached to the supporting clamping plate 310, the outer frame a is moved to make the boundary line to be cut coincide with the observation line, after the coincidence, the telescopic rod 3211 works, the telescopic end pushes the pressing clamping plate 322 to approach the outer frame a until contacting with the outer frame a, the outer frame a is clamped and fixed by cooperating with the supporting clamping plate 310, at this time, the outer frame a is fixed in the channel, then the other end of the outer frame a contacts the ground (in the state shown in fig. 9), and then the rolling cutter 400 is driven by the hand-held handle 411 to move along the movement starting point of the fixed track in the channel to the movement ending point, thereby forming the cutting boundary line a, so as to cut off the redundant part of the side of the outer frame a to be cut.
