Abstract: A rip fence adjustment structure includes a guide rail, a first slide slidably coupled to the guide rail and fixedly connected with a rip fence, a micro-adjustment device mounted in the first slide, a second slide slidably coupled to the guide rail and connected to the first slide by the micro-adjustment device for movement with the first slide. Thus, after moved the first slide to achieve coarse adjustment of the position of the rip fence, a second locking member is fastened up to lock the second slide, and then the micro-adjustment device is operated to drive the first slide in moving the rip fence, and then a first locking member is fastened up to lock the first slide, achieving fine adjustment of the position of the rip fence.

Abstract: A viewing window for a band saw machine includes a cover plate and a transparent plate mounted between two locating portions of the cover plate and facing a window opening penetrating through external and internal sides of the cover plate, such that the transparent plate is located between the locating portions of the cover plate. Thus, the transparent plate can be quickly and conveniently assembled on the internal side of the cover plate.

Abstract: A saw blade tension adjusting apparatus of a band saw machine includes a retaining base, a movable base movably connected with the retaining base through two opposite sliding shafts, and a control unit having a handle and a cam connected with the handle so as to be driven to rotate between a tightening position and a loosening position. When the cam is located at the tightening position, the movable base is lifted by a large diameter portion of the cam to tighten the tension of a saw blade, and when the cam is located at the loosening position, the movable base is moved downwards to lean on a small diameter portion of the cam for loosening the tension of the saw blade.

Abstract: A disk spray device includes a shell having a top air inlet and an annular air outlet, a fan for sucking air from above the device and distributing the air through the annular air outlet to generate an air cushion around the shell, and a spray tube mounted around an outer periphery of the shell and having a plurality of nozzles adjacent to the air outlet of the shell. The spray tube is adapted to be connected with a water supply device such that water running in the spray tube can be sprayed into water mist through the nozzles of the spray tube. The water mist can be further radially delivered far away by the flow of air exhausted out of the annular air outlet of the shell by the fan.

Abstract: A disk spray device includes a shell having a bottom air inlet and a lateral air outlet, a fan rotatably mounted in the shell for streaming air through the bottom air inlet into the shell and then out of the lateral air outlet, and a spray tube mounted around an outer periphery of the shell and having a plurality of nozzles near the lateral air outlet of the shell. The spray tube is adapted to be connected with a water supply device such that water running in the spray tube can be sprayed into water mist through the nozzles of the spray tube. The water mist can be further delivered far way by the wind that is exhausted out of the lateral air outlet of the shell by the fan.
