It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0025] Please refer to Figures 1-4As shown, a sub-saw convenient to adjust, including a sub-saw main body 1, the sub-saw main body 1 is installed in the first support 2, the first support 2 is arranged inside the second support 3, the second support 3 is arranged inside the third support 4;

[0026] One end of the first support 2 is hinged with one end of the second support 3, the other end of the first support 2 is provided with a first connecting part 5, the third support 4 is provided with a second connecting part 6 relative to the first connecting part 5, the first connecting part 5 is provided with an operating part passing through the second connecting part 6, so that the first connecting part 5 is close to or away from the second connecting part 6.

[0027] Preferably, the operating part is a screw, one end of the screw is rotationally arranged in the through hole of the first connecting part, and the other end is threadedly connected in the through hole of the second connecting part, by rotating the screw, the first connecting part is driven to lift, at this time, the first support takes the hinge point as the rotation center, drives the sub-saw to flip up and down, so as to change the flushness of the end face of the sub-saw and the end face of the mother saw.

[0028] In the embodiment, one end of the second support 3 is hinged with one end of the third support 4, the side wall of the third support 4 is provided with a first through hole 7 for passing through the operating part, both side walls of the third support are provided with the through hole, taking the left side through hole as an example, a screw is threadedly passed through the through hole, by rotating the screw, the screw pushes the tail of the second support, because the front end of the second support is hinged, the second support swings horizontally with the hinge point as the rotation point, in turn drives the sub-saw blade to swing to the left side, and the screw on the right side drives the sub-saw blade to swing to the right side.

[0029] Through the above structure, the sub-saw of the present application can adjust the flushness in the horizontal direction and the vertical direction.

[0030] In the embodiment, the lower end of the third support 4 is provided with a moving part 8, the moving part 8 is threadedly matched with a screw rod 9, when the screw rod is rotated, the thread drives the moving part, in turn drives the whole sub-saw to move forward and backward.

[0031] In the embodiment, both sides of the third support 4 are provided with lifting parts 10, the lifting parts 10 pass through optical shafts 11, realizing the whole sub-saw to move up and down.

[0032] Through the above structure, the sub-saw can be adjusted in four dimensions.

[0033] In the embodiment, one end of the first support 2 is provided with a first hinge hole 12, the second support 3 is also provided with a first hinge hole 12, the hinge pin passing through the two holes can realize the relative hinge of the two supports.

[0034] In the embodiment, one end of the second support 3 is provided with a second hinge hole 13, and one end of the third support 4 is also provided with a second hinge hole 13, and the two supports can be hingedly connected by passing a hinge pin through the two holes.

[0035] In the embodiment, the sidewall of the first support 2 is provided with a first clamping hole 14, and the second support 3 is provided with a first clamping groove 15 opposite the first clamping hole 14.

[0036] The bottom of the second support 3 is provided with a second clamping hole 16, and the third support 4 is provided with a second clamping groove 17 opposite the second clamping hole 16.

[0037] After being adjusted to the appropriate position, a screw is passed through the clamping hole and the clamping groove to achieve locking.

[0038] In the embodiment, the hole diameter of the first connecting part 5 is larger than the hole diameter of the second connecting part 6. Since the first support will swing relative to the second support, the hole diameter of the first connecting part needs to be larger than the hole diameter of the second connecting part, so that the screw can pass through.

[0039] In the embodiment, one end of the lifting part 10 is provided with a locking part 18 passing through the side plate, and the locking part 18 is provided with a first pointer 19, and one side of the first pointer 19 is provided with a scale, which can remind the user of the distance moved.

[0040] In the embodiment, one side of the screw rod 9 is provided with a second pointer 20, and the sidewall of the third support 4 is provided with a scale matched with the second pointer 20, which can remind the user of the distance moved.

[0041] The above is only the preferred embodiment of the present application, and is not intended to limit the scope of the present application. Other principles and basic structures that are the same as or similar to the present application are within the scope of the present application.
