A compound saw includes a base, a housing, a transmission component and a table, the rear end of the table is rotatably connected to the housing, and is engaged with the cutter head through the transmission component, so as to expose the cutter head out of the first cutting slit or out of the second cutting slit when the front end of the table swings upward and downward. The cutter head of the compound saw can be switched between the bench cutting mode and the miter cutting mode. Accordingly, on one hand, the structure for switching between modes is simple and does not require the cooperation of too many parts; on the other hand, the switchover can be realized simply by manually operating the movable bench, without too many operations.

A multipurpose cutter table comprises a table member having a long hole in which a saw blade is installed; a pair of leg members foldably installed on a bottom surface of the table member and supporting the table member; a pair of side supporting members installed to be adjustable in length on both sides of the table member and to support a cutting object on both sides of the table member; and an upper surface supporting member foldably installed on an upper surface of the table member and installed so that the cutting object is placed on the upper surface of the table member. Accordingly, a cutting object longer than the table member can be stably placed by the side supporting member, the height of the horizontal fixed frame can be freely adjusted, and a huge working space placing a cutting object before and after cutting can be obtained.

An oil pressure mobile device for a wood working machine is provided in a wood working machine, including a power mechanism and a lifting mechanism. The power mechanism is provided with an oil hydraulic cylinder having its inner wall annularly mounted with a piston fixed with a telescopic rod. The lifting mechanism is disposed with two wheel pressing plates at the underside of the wood working machine. The two wheel pressing plates are jointly provided with a connecting link connected with the telescopic rod, and respectively installed with a moving wheel. Thus, the telescopic rod is driven by the power mechanism to extend or retract and actuate the wheel pressing plates to produce angular variation to make the moving wheels stretch out of the housing of the wood working machine for facilitating shifting of the wood working machine with less labor.

A table saw has a base assembly, a table assembly supported by the base assembly, and a saw assembly supported by at least one of the table assembly and the base assembly. The saw assembly includes a saw blade extending through the table assembly. The base assembly has at least one tube connected to the table assembly.

A post 22D may be disposed between holders 22H. Post 22D preferably does not extend from panel 22 as much as holders 22H. Post 22D may have a protrusion 22DD. Pushstick 70 may also have a detent or protrusion 70D extending therefrom. Preferably protrusion 70D moves past protrusion 22DD as pushstick 70 is moved along posts 22HP. Protrusions 70D and 22DD may contact, preventing pushstick 70 from moving along panel 22.

Persons skilled in the art will recognize that protrusions 70D and/or 22DD may engage notches in panel 22 and/or pushstick 70, respectively. Persons skilled in the art will recognize that the interaction of protrusions 70D and/or 22DD can be used instead or in conjunction with the friction-based retaining arrangement, i.e., where friction is created between narrow area 71N and post 22HH, discussed above.

Holders 22H and/or post 22D are preferably integrally molded with panel 22. Accordingly, pushstick 70 may be held unto the panel 22 without requiring any additional parts.

Persons skilled in the art may recognize other additions or alternatives to the means disclosed herein. However, all these additions and/or alterations are considered to be equivalents of the present invention.
