Description

Technical Field

[0001] The utility model relates to the technical field of miter saws, in particular to a horizontal moving device for a miter saw blade. Background Art

[0002] A miter saw is a movable electric saw used to cut wood, plastic, non-ferrous metals, etc. It consists of a base, a working disk, a motor, a saw blade, a saw blade box, and a linear motion structure. Among them, the horizontal linear motion structure of the saw blade is used to move the saw blade along a vertical plane, so that the miter saw has a larger cutting range and strictly prevents the saw blade from moving horizontally.

[0003] Existing miter saws mainly use a pull rod structure as a guide so that the saw blade can move forward and backward. One end of the pull rod structure is fixed to the saw blade box, and the other end slides on the workbench support. However, when using the pull rod structure, space must be provided behind the saw blade box during the use of the machine so that the pull rod structure can extend when the saw blade is close. Therefore, first of all, it is necessary to pay attention to whether there is an object at the rear end of the machine. If there is an object, it will affect the movement of the pull rod structure. If the pull rod is accidentally touched during the cutting process, it will affect the cutting of the machine; secondly, the pull rod structure takes up a large space for operation and cannot be placed against a wall for use.
