As shown in Figures 1 to 6, a multifunctional cutting machine includes: a frame main body 1 having an upper base plate 11 and a lower base plate 12 arranged in parallel; a longitudinal guide device 2 fixed between the two base plates; a transverse guide device 3, Move up and down along the longitudinal guide device 2; the cutting device 4 moves horizontally along the transverse guide device 3; wherein, the cutting device 4 is rotated and has two working positions, and when it is in the first working position, it is used to place it on the lower base plate 12. When the object is located at the second working position, it at least partially penetrates the upper bottom plate 11 and cuts the object located thereon. In this embodiment, the frame main body 1 is used as the equipment main body of the whole cutting machine, and plays a supporting role. During the horizontal movement of the cutting device 4 along the lateral guide device 3, the cutting device 4 obtains the first degree of freedom, and the cutting device 4 obtains the first degree of freedom. During the vertical movement of the guide device 3 along the longitudinal guide device 2, the cutting device 4 obtains a second degree of freedom, and the above two degrees of freedom enable the cutting device 4 to achieve straight cuts of various depths. During specific processing, as shown in Figure 8, the cutting depth and linear motion speed of the cutting device 4 can be directly controlled by applying force to the object placed on the lower base plate 12, or, through such as an air cylinder or a motor screw assembly, etc. The power device automatically controls its linear motion, and manually controls its cutting depth, or, through a power device such as a cylinder or a motor screw assembly, automatically controls its cutting depth, and manually controls its linear motion; and for the cutting of the second working position The action, as shown in Figure 7, can adopt the same control form as above after its part penetrates the upper base plate 11. The above working modes are all within the protection scope of the present invention. Through the above method, the multifunctional cutting machine can at least obtain working modes similar to those of a hand-held cutting machine, a pressure saw and a sliding table saw.

In the above embodiment, when the cutting device 4 is in the second working position, the part penetrates the upper base plate 11, which may be only the penetration of the saw blade structure. This type of penetration can minimize the penetration area of the upper base plate 11, ensuring Its strength and processing difficulty.

As a preference of the above-mentioned embodiment, as indicated in Fig. 1 and Fig. 2, a positioning device 21 is arranged on the longitudinal guiding device 2, which is used to fix the lateral guiding device 3 at any specified height, wherein, the specific quantification of the height can be Realized by the scale set on it.
