Problems solved by technology

[0007] In addition, in the case of a combination of a tension spring and a link mechanism to obtain a sufficient restoring force of the switch cover, it is necessary to secure an operating space for the link mechanism, and in this regard, the cutting will be realized. It is difficult to miniaturize the machine

Embodiment Construction

[0021] Next, an embodiment of the present invention will be described based on FIGS. 1 to 4 . 1 and 2 show a cutting machine 1 according to this embodiment. In the present embodiment, a portable (handheld) cutter in which the user moves the cutting material W by hand is exemplified as the cutter. This cutter 1 includes: a base 2 placed on the cutter W; and a cutter main body 10 supported on the upper surface side of the base 2 .

[0022] The cutting machine main body 10 is supported on the base 2 by the support part 3 on the front side (right side in FIG. 1 ) of the cutting travel direction of the base 2 and the support part 4 on the rear side (left side in FIG. 1 ) of the cutting travel direction. surface side. In this example, the cutting machine main body 10 is supported so that it can tilt left and right with respect to the direction of cutting progress, that is, it has the function of performing so-called bevel cutting. It is supported tilting up and down, that is, it ...

Abstract

The invention provides a switch shield of a cutter in a cutting machine. In the cutting machine such as the movable portable disc saw bed held by the user, the switch shield for covering the circular saw cutter projecting from the lower surface of the bottom seat is forced to the off direction so that the switch shield can be maintained in the off position reliably. The constitution is that two extension springs are arranged between the switch shield and the cutter box so as to improve the force to the off position side; and two extension springs are installed in parallel in the direction vertical to the main-shaft axis to get a compacted accommodation.

Description

technical field [0001] The present invention mainly relates to a switchable cover (so-called protective cover) that covers the lower side of the circular cutter protruding from the tool box for approximately half a circle in a cutting machine such as a portable circular sawing machine. ). Background technique [0002] A portable circular saw machine that is held and moved by a user includes: a base placed on a cutting member; a cutting machine body supported on the upper surface side of the base, wherein the cutting machine body further includes: a motor as a driving source; And the rotating circular cutter; the cutter box covering the upper half of the cutter. The lower side of the cutter protrudes from the knife case for approximately half the circumference, and protrudes toward the lower surface side of the base. The range protruding toward the lower surface side of the base of the cutter is covered by a switch guard called a so-called guard. The guard is rotatably sup...
