As shown in FIG. 1 and FIG. 2 again, it is shown that the sawing machine is completed and is in a working state. In this state, the driver 35 is suspended above the working surface 211 of the saw table 20. When the workpiece to be cut is placed and positioned On the working surface 211 (not shown), the extension piece 50 and the fixed wing 122 can provide the workpiece with a larger support length, and the support arm 33 of the sawing unit 30 is operated to drive the saw blade 34 and The purpose of sawing the workpiece to be cut can be achieved by making the guide seat 32 slide along the support seat 31 .

As shown in FIG. 4 , the extension member 50 is shown in a deployed position and can support the workpiece. At this time, the shoulder portion 54 is opposite to the side surface 11 , and the extension surface 51 is connected to the long axis X along the long axis X. On one side of the top surface 15 , the bottom side 522 is opposite to the bottom surface 172 of the groove, the elastic member 40 springs against the bottom side 522 , and the block 55 abuts against the adjusting screw 60 , and the adjusting screw 60 is adjusted by adjusting the adjusting screw 60 . The horizontality of the extension surface 51 can be adjusted by screwing in or out relative to the side surface 11 .

When the sawing machine is temporarily not in use and is to be stored or packaged for transportation, the operator first operates the extension piece 50 to convert from the unfolded position of FIG. 4 to a folded position (as shown in FIGS. 5 to 6 ). During the folding operation (see FIG. 5 ), the shaft 18 (the center line L1 ) will be pivoted to rotate, and the elastic member 40 will be slightly deformed by the extrusion of the pivot end 52 , when the extension piece 50 is operated to the folded position (see FIG. 6 ), the shoulder 54 is opposite to the top surface 15 , and the extension surface 51 is perpendicular to the top surface 15 . The setting position is located between the center line L1 of the pivot portion 174 and the side surface 11 . The elastic force of the elastic member 40 can bounce against the side end surface 521 adjacent to the bottom side surface 522 to ensure that the extension member 50 is located at the folded position. It will not easily rotate toward the unfolded position. At this time, the protrusions 524 abut against the side surface 171 of the groove, which can ensure that the extension piece 50 is kept substantially perpendicular to the top surface 15, and can reduce the size of the saw cutter along the side surface 171. The length of the long axis extending to X can reduce the overall volume of the sawing machine and reduce the handling cost.

Next, the operator operates the saw table 20 and the sawing unit 30 to rotate 45 degrees to the left side of FIG. 1 relative to the machine base unit 10 . Continuing, the operator operates the support base 31 to rotate relative to the axle base 22, and the support base 31 can drive the sawing unit 30 as a whole to rotate relative to the saw table 20 with the axis L as the rotation center until the saw blade 34 When it is rotated to the outside of the rear side edge 14 and the saw blade 34 is substantially parallel to the working surface 211 , the sawing unit 30 can be operated into a folded state (see FIG. 7 ). At this time, as shown in FIG. 8 , the inner end of the guide member 321 abuts against the limiting block 19 (see FIG. 8 ), which can provide better support for the folded sawing unit 30 .

As shown in FIG. 9 , when the sawing unit 30 operates in a folded state, the first foot seat 111 of the machine base unit 10 , the second foot seat 322 at the end of the guide member 321 , and the extension member 50 are used. The third feet 56 together produce a positioning plane P, which can make the sawing machine stand upright on the ground, and can increase the bottom area of the sawing machine when it is placed upright, so as to ensure stable positioning of the sawing machine when it is stored. , and the sawing machine can be stored in a small space, which is conducive to the use of space.

At this time, the side surface 12 , the carrying handle 121 , and the fixed wing 122 are disposed upward, and the carrying handle 121 is convenient for the operator to carry and move.

Thus, with the extension 50 being pivotable and mounted to the base unit 10 and enabling the extension 50 to be converted relative to the base unit 10 between a deployed position and a folded position, support for the workpiece can be provided, as well as The length of the base unit 10 corresponding to the long axis X can be shortened by folding in time. Furthermore, the first foot seat 111 of the base unit 10, the second foot seat 322 at the end of the guide member 321, and the third foot seat 56 of the extension member 50 in the folded position are also used to cooperate together, so that the The sawing unit 30 stands upright on the ground when it is operated in a folded state, and is quite convenient to use as a whole.

To sum up, the sawing machine of the present invention has a folding extension piece, and the extension piece 50 can be switched between the unfolded position and the folding position relative to the base unit 10, and the workpiece can be unfolded and supported or folded over in time. The length of the sawing machine extending along the long axis X can be reduced, the overall volume of the sawing machine can be reduced, and the handling cost can be reduced, which can indeed achieve the purpose of the present invention.
