Description

Technical Field

[0001] This utility model relates to a fixture, and more particularly to a general-purpose fixture for circular saws that is easy to use, improves practicality, and provides stable clamping. Background Technology

[0002] Existing power saws are handheld rotary cutting machines equipped with toothed discs or grinding wheels. They cut materials by driving the toothed discs or grinding wheels to rotate. Existing power saws generally include handheld circular saws and track-mounted circular saws. When a handheld circular saw is used to make a straight cut on a material, a straight-edge tool such as a ruler must be used to ensure the accuracy and quality of the cut. When a track-mounted circular saw is used to make a straight cut on a material, the track is set in a straight line, so the existing track-mounted circular saw can cut a straight line on the material using the track. Furthermore, the straight-edge tool used with the existing handheld circular saw and the track used with the existing track-mounted circular saw need to be clamped and positioned by a fixture. The existing fixture clamps and positions the straight-edge tool or the track by pressing down a clamping mechanism.

[0003] However, while existing track-mounted circular saws can provide a straight-line cutting effect, they require pre-installation and alignment on the sheet material, which is time-consuming. Furthermore, they can only be used with corresponding track-mounted circular saws and are not compatible with existing handheld circular saws or track-mounted circular saws of different sizes, thus limiting their practicality. Additionally, the overall size of existing track-mounted circular saws makes them inconvenient to carry and store. Therefore, currently, for straight-line cutting of sheet material, existing handheld circular saws can only be used with straight-edge tools. However, existing track-mounted circular saws can only be used with corresponding tracks. Therefore, it is not possible to use existing handheld circular saws and track-mounted circular saws with a single fixture, which is relatively inconvenient to use and increases the cost of use. Furthermore, the existing fixtures position the straight-edge tool or track by pressing down. The frictional force of the pressing down on the fixture itself, the straight-edge tool, and the track can easily cause damage or breakage to the existing fixture, straight-edge tool, or track. Therefore, there is room for improvement regarding the above-mentioned problems and shortcomings. Utility Model Content

[0004] Therefore, to address the problem that existing circular saws require the use of straight-edge tools or tracks for straight cutting, and cannot be used with a single fixture, thus limiting their convenience and practicality, and that the pressing clamping method of existing fixtures easily leads to damage or breakage of the fixture, straight-edge tools, or tracks, this utility model provides a universal fixture for circular saws that can be used with straight-edge tools or tracks of different sizes, greatly improving practicality and convenience. Furthermore, the inclined clamping mechanism clamps and positions the straight-edge tools or tracks, effectively preventing damage to the fixture itself, straight-edge tools, and tracks due to the friction caused by pressing. This provides a universal fixture for circular saws that is easy to use, improves practicality, and provides stable clamping.
