[0006] Furthermore, the fixture includes a base plate with fixing blocks installed on the left and right sides of the base plate. These two fixing blocks are a left fixing block on the left and a right fixing block on the right. The right fixing block has adjusting screw holes in the left and right directions, and an adjusting bolt is installed in the adjusting screw holes. The left end of the adjusting bolt has a top plate, and the right end of the adjusting bolt has an adjusting handle. The workpiece is clamped between the left fixing block and the top plate.

[0007] Furthermore, the mounting base has left and right sliding tracks, on which a slider is mounted, and the fixture base plate is mounted on the slider; there are also pin screw holes on the side of the sliding track, and pin bolts are installed in the pin screw holes and press against the side of the slider.

[0008] The beneficial effects of this utility model are: such a sawing device has the advantages of being able to select different saw blades and being easy to use. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] As shown in the figure, a saw blade replaceable sawing device includes a mounting base 1, a workpiece clamp 2 on the mounting base, a column 3 mounted on the mounting base, a lifting cylinder 31 mounted in the middle of the column, and a saw blade 5 driven by a motor 4 mounted on the column. The device is characterized by: a shaft hole 32 on the column, and a laterally arranged rotating shaft 6 installed in the shaft hole; a handle 61 at the left end of the rotating shaft; and a rotating disk 62 fixed at the right end of the rotating shaft; one motor and one saw blade driven by it constitute a set; multiple sets of saw blades driven by the motor are also included. Each saw blade is installed around the rotating disk and has a positioning hole on the column, which is the first positioning hole 33. A positioning plate 63 is installed on the rotating shaft on the side of the column and is fixed to the rotating shaft. The positioning plate has multiple positioning holes, which are the second positioning holes 631. During the rotation of the rotating disk, when any saw blade rotates to the lowest position, there is a second positioning hole corresponding to the first positioning hole. The saw blade also includes a pin 7 inserted into the first positioning hole and the second positioning hole. The saw blades are of multiple models.

[0016] The saw blades mentioned are of multiple models; for example, some saw blades are thicker, some are thinner, some have more teeth, and some have fewer teeth.

[0017] The first positioning hole and multiple second positioning holes are provided to facilitate the positioning of the saw blade when using a particular saw blade for sawing.

[0018] The lowering of the lifting cylinder allows the saw blade to move downwards during sawing.

[0019] The above-mentioned features of this utility model allow for the selection of a specific saw blade, making it convenient to use.

[0020] Furthermore, the fixture includes a fixture base plate 21, with fixing blocks installed on the left and right sides of the fixture base plate, namely a left fixing block 22 on the left and a right fixing block 23 on the right. The right fixing block has adjusting screw holes in the left and right directions, and an adjusting bolt 24 is installed in the adjusting screw holes. The left end of the adjusting bolt has a top plate 25, and the right side of the adjusting bolt has an adjusting hand ring 26. The workpiece is clamped between the left fixing block and the top plate.
