Abstract

A multifunctional tool and a core structure thereof are provided. The core structure comprises a central frame as well as a power mechanism and a transmission system mounted to the central frame. The central frame includes an extension (22) located in a front portion of the central frame as a base to fix various working assemblies. The core structure further comprises a reciprocating movement platform, the reciprocating movement platform is connectable to a rear end of a work executing element of various working assemblies through a connection interface provided on a front end of the reciprocating movement platform, the connection interface being entirely located within the extension, and the transmission system transmits power output by the power mechanism to the reciprocating movement platform so that the reciprocating movement platform makes reciprocating movement forward and backward with respect to the central frame and drives the work executing element connected to the connection interface to make desired movement. The core structure is connected to working assemblies with different functions and specifications and the operation of replacing the working assemblies is simplified and facilitated.

Abstract

Disclosed are a machine head locking structure of a compound saw and a compound saw. The machine head locking structure comprises a locking fastener (7) located on one of a frame (5) and a working turntable (2) of the compound saw, wherein an overlapping body (71) is provided on the locking fastener (7), an overlapping cooperation body (51) able to form a lock catch with the overlapping body (71) is provided on the other one of the frame (5) and the working turntable (2), and the overlapping body (71) is a protrusion or recess on the locking fastener (7) and the overlapping cooperation body (51) is a matching recess or protrusion. The locking fastener (7) can move between a locking position and an unlocking position. When in the locking position, the overlapping body (71) on the locking fastener and the overlapping cooperation body (51) are fitted together; and when in the unlocking position, the overlapping body (71) on the locking fastener is disengaged from the overlapping cooperation body (51).

Abstract

Disclosed is a compound saw comprising: a frame (8), fixed to a bench panel (9) at its top; a base assembly (1); a working turntable assembly (2); a rocker frame holder (4), which is located between the frame (8) and the working turntable assembly (2) and is hinged to the frame (8) and the working turntable assembly (2), respectively; a saw blade (6), which is used to cut a workpiece; and a saw blade lifting device (12), provided at a lower portion on one side of the frame (8) remote from the hinged end of the frame (8) that is hinged to the rocker frame holder (4), wherein the saw blade (6) is mounted on the saw blade lifting device (12), and the saw blade (6) is able to perform a lifting movement relative to the frame (8), so as to be switched between a bench saw mode, in which the saw blade lifting device (12) lifts the saw blade (6) to an upper portion of the frame (8) such that part of the saw blade (6) is higher than an upper surface of the bench panel (9), and a mitre saw mode, in which the saw blade lifting device (12) lowers the saw blade (6) to the lower portion of the frame (8) such that the entire saw blade (6) is below the upper surface of the bench panel (9).
