Abstract

The utility model relates to an adjustable laser indicating device for a cutter, wherein the cutter is provided with a working platform, a saw arm and a circular saw blade. The laser indicating device is characterized in that a sliding base, which is actively arranged on the upper edge of the rear of the saw arm and the position of which is adjustable along the left and the right direction of the circular saw blade; a laser indicating lamp, which is fixed on the sliding base and can be connected with an external power supply, wherein the lamp cap toward the working platform can project an indicating line parallel to the circular saw blade; by changing the position of the sliding base, the display position of the indicating line projected on the working platform can be flexibly adjusted, so as to meet the requirements for different saw cuttings and achieve the battery-free advantage.

Description

The adjustable laser indicating device of cutting machine

[technical field]

This is novel to relate to a kind of cutting machine, adjusts the index line position and is suitable for different sawing needs and exempts from adjustable laser indicating device with the cutting machine of advantages such as battery to reach but particularly relate to a kind of elasticity.

[background technology]

See also shown in Figure 1, tradition cutting machine 10 mainly is pivoted with one at place, a workbench 11 rears can lift the saw arm 12 that opens up and down, these saw arm 12 inner shafts are provided with a saw blade 13, on the saw arm 12 and axle be provided with an eye-protection cover 14, this eye-protection cover 14 is the outer peripheral edges that cover in saw blade 13 at ordinary times, can be on these workbench 11 table tops for placing a base material 100, its place, rear is provided with a striker plate 15 and can keeps off to this base material 100, when the operator presses down this saw arm 12, this eye-protection cover 14 is subjected to a connecting rod 16 start meetings and is gradually raised, saw blade 13 is exposed so that this base material 100 is carried out sawing, in addition, be positioned at place, saw blade 13 axle center and more be equiped with a laser indicating device 17, this laser indicating device 17 is in the form of annular discs, its periphery has a lamp hole 171 at least, and inside is equiped with a laser lamp 172 and a battery 173, battery 173 provides the laser lamp 172 power supplys, laser lamp 172 sees through lamp hole 171 can outwards project a luminous point, because this laser indicating device 17 is along with saw blade 13 rotates together, when luminous point is being done under the rotation of 360 degree fast, can on the table top of workbench 11, compile projection go out an index line that is parallel to saw blade 13, this index line mainly acts on and provides the operator and can know the position of distinguishing 13 times cuttves of saw blade, if draw on the base material 100 line of ink marker arranged, then can align, so can cut out the workpiece of just size with index line.

Really can project index line for the purposes of aiming at above-mentioned laser indicating device, yet its usability still has not enough place, when generally base material 100 being cut off, be to get useful position as workpiece, no position should be given up at base material 100 in the position of 13 times cuttves of saw blade, when the operator will take position, base material 100 left side as workpiece, this laser indicating device 17 is the limits, left side that are installed in saw blade 13, make index line be projeced into down the left side of cutter position, so just can not cut to the position that belongs to workpiece during 13 times cuttves of saw blade, but each operator's work habit difference, when if the operator wants to take position, base material 100 the right as workpiece, because this laser indicating device 17 is to be fixed in saw blade 13 left sides, its index line can't be incident upon down the right side of cutter position, therefore the aligning of right direction can't be provided, there is its restriction to exist in the use, often cause operator's inconvenience greatly, in addition, this laser indicating device 17 is to be installed on the saw blade 13, be to connect external power source during action, must be dependent on internal cell 173 and supply with laser lamp 172 electric energy, in use for some time, the electric weight of its internal cell 173 will deplete, just need remove laser indicating device 17 and take off this moment from saw blade 13, again load onto again after installing new battery, comparatively bother in the use.

[utility model content]
