Problems solved by technology
[0004] Although the above-mentioned saw blade angle adjustment device can achieve the purpose of adjusting the processing angle of the saw blade unit, because the distance between the locking bolt and the shaft bolt is short, and the saw blade unit connected to the rotary member has a considerable weight , the operator must first hold the saw blade unit with one hand before unscrewing the locking bolt, and then use the other hand to go around the rear of the sawing machine to operate the locking bolt, which is inconvenient to operate
[0005] Furthermore, the tightening force generated by the locking bolt on the rotating part may be insufficient in locking force and inaccurate in the angular positioning of the saw blade unit after a period of use.

Embodiment Construction
[0029] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:
[0030] figure 1 , figure 2 and Figure 5 A preferred embodiment of the angle adjustment device of the sawing machine of the present invention is shown. The sawing machine also includes a base unit 100 , a saw table 200 that can rotate relative to the base unit 100 , and a sawing unit 300 that can rotate relative to the saw table 200 and has a saw blade 301 . The angle adjusting device of this embodiment is mainly suitable for adjusting the sawing angle of the sawing unit 300 , and includes a fixing member 10 , a positioning unit 20 and a locking unit 30 .
[0031] with reference image 3 and Figure 4 , the fixing part 10 of this embodiment is connected to the saw table 200, the fixing part 10 is in the shape of a fan-shaped plate, and has an axis L approaching the top surface of the saw table 200 and a flange 11 arranged around the axis L and a plurality...

The invention provides an angle adjusting device of a sawing machine. The angle adjusting device comprises a fixing piece and a positioning unit, wherein the fixing piece is provided with an axis and a flange which is arranged around the axis; the positioning unit is provided with a body, a first clamping block, a second clamping block and a fixed pawl; the body is provided with an axle hole; the first clamping block and the second clamping block are nested in the body; the fixed pawl is arranged in the axle hole in an axle way, and is provided with a wrenching part. According to the angle adjusting device, when the wrenching part is operated, the first clamping block and the second clamping block can be driven to generate approaching clamping or departure release relative to the flange; therefore, the sawing machine realizes an angle adjusting purpose.
Description
technical field [0001] The invention relates to a sawing machine, in particular to an angle adjustment device of the sawing machine. Background technique [0002] There is an existing saw blade angle adjustment device for a sawing machine, which locks a support seat on the top surface of a workbench that can rotate relative to a base, and enables a rotating part to rotate using a shaft bolt and the shaft is set on the On the supporting base, the rotating part has an arc slot and a locking bolt that can pass through the arc slot and be locked on the supporting base, and a saw blade unit is installed on the rotating part. [0003] When the locking bolt is unscrewed, using the cooperation between the arc slot and the locking bolt, the rotating part can drive the saw blade unit to pivot with the center line of the shaft bolt as the center point of rotation, and then When the locking bolt is locked, the inclination angle of the saw blade unit can be fixed. [0004] Although the...
