Referring to fig. 1 and 2, the saw cutting machine is shown in a working state, in which the driver 35 is suspended above the working surface 211 of the saw table 20, when a workpiece to be cut is positioned on the working surface 211 (not shown), the extended member 50 and the fixed wing 122 can provide a longer supporting length for the workpiece, and the supporting arm 33 of the saw cutting unit 30 is operated to drive the saw blade 34 and slide the guiding seat 32 along the supporting seat 31, so as to achieve the purpose of cutting the workpiece to be cut.

As shown in fig. 4, the extension member 50 is shown in an extended position and can support a workpiece, at this time, the shoulder 54 is opposite to the side surface 11, the extension surface 51 is connected to one side of the top surface 15 along the long axis X, the bottom side surface 522 is opposite to the groove bottom surface 172, the elastic member 40 is elastically abutted against the bottom side surface 522, the stopper 55 is abutted against the adjusting screw 60, and the levelness of the extension surface 51 can be adjusted by adjusting the adjusting screw 60 to be screwed in or out relative to the side surface 11.

When the saw cutting machine is temporarily not used and is to be stored or packaged for transportation, an operator first operates the extension element 50 to convert from the unfolded position of fig. 4 to a folded position (see fig. 5-6), the extension element 50 rotates around the pivot center of the shaft rod 18 (the center line L1) during the folding operation (see fig. 5), the elastic element 40 is slightly deformed by being pressed by the pivot end 52, when the extension element 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, at this time, by the arrangement position of the elastic element 40 between the center line L1 of the pivot 174 and the side surface 11, the elastic force of the elastic element 40 can be elastically abutted against the side end surface 521 adjacent to the bottom side surface 522, which can ensure that the extension element 50 in the folded position can not easily rotate again towards the unfolded position, at this time, the protrusion 524 abuts against the slot side surface 171, so as to ensure that the extending member 50 is kept substantially perpendicular to the top surface 15, thereby reducing the length of the saw cutting machine extending along the long axis direction X, reducing the overall volume of the saw cutting machine, and reducing the transportation cost.

Next, the operator operates the saw table 20 and the sawing unit 30 to rotate at an angle of 45 degrees to the left side of fig. 1 with respect to the base unit 10. Continuing, the operator operates the supporting seat 31 to rotate relative to the shaft seat 22, the supporting seat 31 can drive the whole sawing unit 30 to rotate relative to the saw table 20 with the axis L as a rotation center until the saw blade 34 rotates to the outside of the rear side edge 14 and the saw blade 34 is substantially parallel to the working surface 211, so that the sawing unit 30 can be operated to be folded (see fig. 7), at this time, as shown in fig. 8, the inner end of the guiding member 321 abuts against the limiting block 19 (see fig. 8), and better support can be provided for the folded sawing unit 30.

As shown in fig. 9, when the sawing unit 30 is folded, the first foot seat 111 of the base unit 10, the second foot seat 322 at the end of the guiding member 321, and the third foot seat 56 of the extending member 50 jointly generate a positioning plane P, so that the sawing machine can be vertically placed on the ground, the bottom area of the sawing machine can be increased when the sawing machine is vertically placed, the sawing machine can be stably positioned when being stored, and the sawing machine can be stored in a narrow space, which is beneficial to the application of space.

At this time, the side surface 12, the carrying handle 121 and the fixing wing 122 are disposed upward, and the carrying handle 121 can be used to facilitate carrying and moving by an operator.

Therefore, by using the extension member 50 to be pivotally mounted to the base unit 10 and enabling the extension member 50 to be switched between the extended position and the folded position relative to the base unit 10, a support for the workpiece can be provided and the base unit 10 can be folded at a proper time to shorten the length thereof corresponding to the long axis X. Moreover, the first foot seat 111 of the base unit 10, the second foot seat 322 at the end of the guiding member 321, and the third foot seat 56 of the extending member 50 at the turning position are used together to cooperate, so that the sawing unit 30 is supported on the ground when operating to the folded state, and the whole use is very convenient.
