A support base 7 is provided on one side of the cutting base. A hand-held cutting machine is hinged and connected to the upper part of the support base. The hand-held cutting machine includes a cutting cover 2, a hand-held rod 1, a cutting blade 18, and a cutting motor 19. On the front side of the cutting base, there is a longitudinally arranged scale straight plate 13, which is arranged perpendicular to the cutting blade. A scale ruler 23 is provided on the scale straight plate. A set of movable clamps is also provided on the scale straight plate. A horizontally arranged sliding clamp sleeve is fixed on the movable clamp. Further, in the present utility model, the sliding clamp sleeve includes a longitudinal plate 17 and a sliding sleeve 12. The longitudinal plate is perpendicularly welded to the movable clamp and is vertically welded to the top of the movable clamp. The sliding sleeve is a C-shaped sleeve, and a limiting slider is provided at the inner top of the C-shaped sleeve. Correspondingly, a linear sliding groove 20 is opened on the sliding plate, and the limiting slider slides in the linear sliding groove. A sliding plate 10 is slidably inserted into the sliding clamp sleeve. A baffle plate 11 is fixed on the sliding plate. The tail end of the sliding plate is connected to a return spring 22. One end of the return spring is connected to the sliding plate, and the other end of the return spring is connected to the outer wall of the sliding clamp sleeve. A transverse support rod 9 is also connected to the outer back of the sliding clamp sleeve. Brake wire sleeves 6 are respectively installed at the tail of the transverse support rod and on the support base. A brake wire 5 is installed in the brake wire sleeve. One end of the brake wire passes through the corresponding brake wire sleeve and is connected to the tail end of the sliding plate, and the other end of the brake wire passes through another brake wire sleeve and is connected to the cutting cover. Further, in the present utility model, a plastic leather sleeve 8 is sleeved on the brake wire.
[0019] Further, in this embodiment, the movable clamp includes an inverted rectangular channel steel block 14, which is buckled on the scale straight plate. A locking bolt 15 is inserted through the side wall of the rectangular channel steel block and presses against the side wall of the scale straight plate. Further, in the present utility model, the two ends of the return spring are respectively hooked on two hooks 21. One hook is fixed on the side wall of the tail end of the sliding plate, and the other hook is fixed on the outer wall of the sliding clamp sleeve. Further, in the present utility model, the support base is composed of two vertical support plates. A rotating shaft 4 is installed between the two vertical support plates. The outer wall of the cutting cover is connected to the rotating shaft through a connecting rod 3 and realizes rotation. Further, in the present utility model, the cutting base is a flat base, and a cutting notch for the downward movement of the cutting blade is provided on the flat base.
[0020] The above structural description is the basic structure of the present utility model, and its working principle is as follows:
[0021] First, slightly press down the whole cutting machine through the hand-held rod. The brake wire is tightened. At this time, the material baffle is pulled to the right by a certain distance and is in the normal position. Then, place the end of the steel pipe to be cut against the material baffle. There is a certain frictional force between the end of the steel pipe and the material baffle. Then the operator holds the hand-held rod and the cutting disc starts to cut the steel pipe. At this time, the brake wire is moderately tightened. After the cutting is completed, the operator slowly raises the hand-held rod. When raising it, the brake wire becomes slack, and the material baffle moves linearly to the left under the action of the return spring. While moving, the material baffle will naturally bring down a section of the cut steel pipe through the frictional force, and the cut steel pipe will not clamp the cutting disc.
[0022] In the present utility model, the scale ruler is applicable to the fixed-length processing of the cut steel pipe. The scale lines on it are set in advance, and the size of the steel pipe protruding can be directly read on the scale ruler, which is very convenient; the movable clamp below can be adjusted in position by loosening the locking bolt.
[0023] In this embodiment, by adding the brake wire, the sliding plate can move linearly, and then drive the material baffle thereon to move together. When the cutting machine is lifted, the material baffle moves during self-resetting, and at the same time drives the cut steel pipe to fall off automatically, avoiding the situation that the cutting disc is clamped and damaged, and having a good protection effect.
[0024] Based on the existing hand-held cutting machine, the present utility model makes improvement measures. One is to add a structure for flexible fixed-length cutting, and the other is to add a structure related to the return spring, so that the material baffle can self-reset, and at the same time drive the cut steel pipe to fall off automatically during resetting, avoiding clamping the cutting disc and damaging it. The actual use effect is obvious, and it has good popularization and utilization value.
