The specific embodiment

Referring to accompanying drawing 1-2, a kind of cutting machine 20 comprises workbench 22, the bearing 24 of support table 22, be located at the guard shield 30 on the workbench 22, adjustable Anchor plate kit 32 that workpiece is applied certain pressure that links to each other with guard shield 30, and the cutting mechanism 26 of being located at workbench 22 lower surfaces 38.

According to the usual occupation mode of operator to this type of cutting machine, the left side is the front portion of cutting machine 20 among definition Fig. 1, and the right side is the rear portion of cutting machine 20.Workbench 22 has upper surface 36, lower surface 38 and with respect to upper and lower surperficial 36,38 vertically extending sidewalls 39.Opening 40 is opened on the workbench 22, is positioned at the front portion of cutting machine 20, is through to lower surface 38 from upper surface 36.Saw blade 28 passes opening 40 from bottom to top.Workpiece 34 can be placed on the upper surface 36 of workbench 22, moves through saw blade 28 along upper surface 36, thereby is cut by saw blade 28.The shape of opening 40 is essentially square.A square saw blade backplate 42 can embed opening 40, and the dust that prevents that is used for to a certain degree enters cutting machine 20 inside, and when the abnormal conditions such as saw blade 28 fractures occurring, backplate 42 can be removed, and the operator is by taking-up saw blade 28 in the opening 40.The centre of backplate 42 offers slit 43, and saw blade 28 can pass through from slit 43.

Cover assembly 30 comprises dismountable support 52 that is connected on the workbench 22, with the adjutage 54 of support vertical setting and coupled extension cover body 55, the left and right sides

guard shield plate

56a, 56b and boot main body 53.Comprise that the guard shield clamp mechanism 57 of clamping knob 50 is with end cover body 59 adjustable being fastened on the adjutage 54.Boot main body 53 belows arrange guide wheel 61, for the reciprocating motion of saw blade 28 provides guiding.The top of boot main body 53 is provided with sweep-up pipe 63, is used for external dust catcher, with the dust sucking-off of cutting generation.
