Description

Technical Field

[0001] The utility model relates to the technical field of right-angle cutting guides for track saws, in particular to a right-angle cutting guide device for a track saw. Background Art

[0002] As the name suggests, a track saw consists of a linear track and a cutting saw. The linear track is composed of a wider straight board and a track, and the cutting saw moves along the track on the straight board through the engagement between the groove at the bottom and the track.

[0003] At present, when a traditional track saw is used to cut a plate, first, the worker draws a straight line on the plate, then places the straight track on the plate, and aligns one side of the straight board with the line on the plate. After alignment, the worker installs the cutting saw on the straight track. At this time, the cutting saw is turned on and pushed so that the cutting saw moves in a straight line along the track, thereby completing the straight-line cutting of the plate.

[0004] Because the traditional linear track is only placed on the plate during installation, but not fixed on the plate. When the track saw is used for cutting, it is easy to be affected by the resistance of the cutting saw blade or the shaking of the hand, which will cause the linear track to shift on the plate, resulting in the problem of not being able to maintain a straight cutting line during cutting.

[0041] The working principle and use process of this utility model:

[0042] In use:

[0043] During installation, first, align the guide groove 34 on the lower slide plate 32 with the guide track 24 on the bottom surface of the guide plate 21. After alignment, insert the lower slide plate 32 into the lower part of the guide plate 21, and make the guide track 28 slide in the guide groove 34. After the lower slide plate 32 and the side baffle plate 31 are installed, flip the flip plate 62, and the flip plate 62 will drive the hook 64 to flip. When the hook 64 flips to one side of the lock track 24, rotate the paddle 66. When the paddle 66 rotates, it will drive The rotating column 65 and the L-shaped block 68 rotate, and when the stopper L-shaped block 68 rotates, it rotates in the square groove 610 and drives the hook 64 to move. At this time, the rectangular rod 69 and the square groove 610 cooperate with each other, so that the hook 64 moves horizontally, and one end of the hook 64 can be hung on the lock track 24. After hanging, the paddle 66 is turned over, so that the positioning hole 67 on the paddle 66 is inserted into the surface of the positioning piece 612, and the auxiliary vertical component 3 can be fixed on the guide component 2.

[0044] After fixing, at this time, align the dovetail groove 4 on the bottom surface of the cutting saw 1 with the dovetail track 22, and insert the cutting saw 1 into the upper part of the guide plate 21, so that the cutting saw 1 slides on the guide plate 21 through the dovetail track 22;

[0045] When the guide plate 21 needs to be lengthened later, first, the pressing bent rod 265 on one side of the guide plate 21 is pressed, and the pressing bent rod 265 will squeeze the damping rod 264 when it moves. At this time, another guide plate 21 is taken, and the first plug-in rod 251 and the second plug-in rod 252 on one side of the guide plate 21 are aligned with the first plug-in hole 261 and the second plug-in hole 262, and they are inserted. After insertion, the pressing bent rod 265 is released, and the pressing bent rod 265 is reset under the action of the damping rod 264. After reset, the locking hole 266 on one side of the pressing bent rod 265 will be inserted into the locking groove 263, and the two guide plates 21 can be spliced ​​to adapt to the length of the plate, and at the same time, it is convenient for later carrying;

[0046] When in use, first, make one side of the side guard plate 31 and the side guard plate 33 contact with the side of the plate to be cut. After contact, the guide plate 21 can be located above the cutting plate. Since the side guard plate 31 and the guide plate 21 are installed vertically, when the cutting saw 1 is moved, the cutting saw 1 cuts in a straight line above the plate.
