When the laser cutting machine for processing hardware is used, the radius of an arc line of a bent pipe is measured firstly, then the electric telescopic rod 6 is adjusted to enable the sum of the electric telescopic rod and the fixing components to be equal to the length of the radius, then the two fixing components are respectively fixed with the bent pipe, after the fixing, the fixing components and the electric telescopic rod 6 are positioned on the same straight line and are coincided with the arc radius line of the bent pipe, after the two fixing components fix the bent pipe, a shape similar to a triangle is formed between the two electric telescopic rods 6 and the bent pipe, and therefore the fixing effect of the bent pipe is achieved, and as shown in figure 1, the state after the fixing is well shown in figure 1.

After the fixation, the disc 5 is driven by an external mechanism to rotate, so that the two fixing components are respectively positioned at two sides of the laser cutting component 8, as shown in figure 8, then the disc 5 is driven by an external mechanism to move horizontally and move towards the laser cutting component 8, the bent pipe is cut by laser, because of the clamping effect of the two fixing components on the bent pipe and the coincidence of the electric telescopic rod 6 and the radius, it is possible to confirm that the bent pipe is a standard arc, and the laser cutting assembly 8 is located in the horizontal moving direction of the disc 5, the movement of the disc 5 is on the radius line of the bend, since the tangent at the cut of the bend is perpendicular to the radius line, therefore, the cutting surface of the elbow pipe cut by the laser cutting component 8 is vertical to the tangent line of the elbow pipe, so that the tangent plane is level and round, thereby being convenient for the tight fit of return bend and straight tube, reducing the influence of interface truncation degree and shape when connecting.

a drive assembly for driving the sprocket 16 to rotate and lock is also included.

Referring to fig. 7 in particular, when the elbow is fixed, the elbow passes through the fixing piece 7, then the driving assembly drives the chain wheels 16 to rotate, all the chain wheels 16 rotate and drive the mounting rods 17 thereon and the clamping wheels 18 to rotate together under the transmission of the chain, the clamping wheels 18 are used for clamping and fixing the elbow, and then the driving assembly locks the chain wheels 16.

Moreover, the plane of the clamping wheel 18 is perpendicular to the tangent line of the arc line of the elbow at the position, so if the elbow is in a standard arc line, the two electric telescopic rods 6 can be superposed with the metal plate of the elbow, namely the clamping wheel 18 can clamp and fix the elbow, and conversely, if the elbow is not in a standard arc line, the clamping wheel 18 in one fixing piece 7 cannot clamp and fix the elbow;

and if the two fixing pieces 7 clamp the bent pipe tightly, when one clamping block 14 is not clamped into the corresponding clamping groove, the bent pipe is not in a standard arc shape, so that the effect of detecting the bent pipe before cutting is achieved, and the quality of subsequent cutting is improved.

Example two, with reference to fig. 9 and 10, in contrast to example one, a second embodiment of a connection assembly is provided;

further, coupling assembling is including fixing the dead lever 22 at 7 outer walls of mounting, dead lever 22 rotates with the one end that electric telescopic handle 6 is relative to be connected, electric telescopic handle 6's outer wall rotates installs gag lever post 23, spacing groove 24 has been seted up to dead lever 22's outer wall, and the inner wall slidable mounting of spacing groove 24 has stopper 25, the one end that electric telescopic handle 6 was kept away from to gag lever post 23 rotates the outer wall of installing at stopper 25, still install the locking piece 26 that is used for locking stopper 25 on dead lever 22, when gag lever post 23 is in the time of being parallel with electric telescopic handle 6, locking piece 26 locks stopper 25.
