IS-like workbench, located in the booth a saw mechanism having a motor and a circular saw blade thereon, and a corner bracket connecting the work table and the saw mechanism, wherein the saw mechanism is rotatably coupled to the work table around a pivot fixed relative to the work table, and is used for cutting the workpiece operation. The sawing work of the traditional miter saw is mainly: the operator first draws the cutting mark line on the part to be cut off, and then performs the tool setting, that is, when the power is turned on, the saw mechanism is pressed, and the workpiece to be cut is moved. The cutting mark line on the workpiece to be cut is aligned with the circular saw blade; thus, when the power is turned on, the circular saw blade is rotated at a high speed under the driving of the motor, and the workpiece can be cut into a size desired by the operator. However, since the operator observes the alignment of the circular saw blade and the cutting mark line by the naked eye, and the saw blade has a certain thickness, it is difficult to report that the circular saw blade [S] 5 1354592 is aligned with the cutting mark line. The whisker will also be pressed down to the sawing mechanism and then the tooling ratio will be reversed. (4) It will often be set up again - the laser alignment device, which can project a laser beam on the surface of the workpiece. This allows the operator to know the position of the lower blade of the circular saw blade very clearly, and to move the workpiece more easily, so that the cutting mark line on the circular silver piece is aligned, the workpiece can be accurately cut into The size desired by the operator β US Pat. No. 648 U22 discloses a oblique broken mine comprising a table, a saw mechanism having a motor and a circular saw blade above the table, and a connection table and a saw mechanism.

A laser alignment device is mounted on the arm, and the laser alignment device can project a laser beam on the surface of the workpiece, so that the operator can clearly know the position of the lower blade of the circular saw blade. The workpiece is accurately cut to the size desired by the operator. However, because the miter saw will produce a lot of sawdust during the cutting process, and the sawdust will fly around, if the laser alignment device is absorbed by the sawdust, the projected laser beam will become more and more bleak and affect The operator's observation makes it difficult for the operator to accurately align the workpiece with the projected laser beam; in severe cases, the laser beam projected by the laser alignment device will be shielded, making it impossible for the operator to quickly and easily. Cut the ground. 1354592 SUMMARY OF THE INVENTION It is an object of the present invention to provide a miter saw that can keep the laser alignment device clean.

The dust collecting device 6 may be at least in active engagement with the fixed shield 33 and the support device 4, in the present embodiment the dust collecting device 6 respectively The saw mechanism 3. is coupled to the support device 4. As shown in the first figure, the dust collecting device 6 includes a pair of side walls 61 and an end wall 62, and the side walls 61 are substantially fan-shaped, and are of course designed as needed. Shape. For effective dust guiding, the end wall 62 The wall 61 and the end wall 62 form a dust collecting passage 63. Here, the dust collecting passage 63 is not a sealed pipe. 15 1354592 = 6. Solid-state pivoting The two drawing axes 66 are fixed with respect to the support 4 and the second pivot 65 and the second holding shaft 66 are arranged on different axes. Referring to the third figure, the supporting device 4 includes the first support that is mated with the table 2. The member 41 and the second support member 42β==the member is widened to define a longitudinal axis 43, and the first support member 4i can be clockwise and counterclockwise with respect to the table 2 about the longitudinal axis 43. Rotating in both directions to tilt-set the angle 'for cutting the workpiece 2〇〇β between the first support member 2 is provided to lock the first support member 4 to the work tightening mechanism 44. As shown in the second figure, the dust collecting device 6 and the second support member 42 are fixedly pivotally connected by the second yoke 66. As shown in the third and tenth views, the second support member 42 is movable relative to the first leg member 41 in the direction of the longitudinal axis 43 and is cut X after reaching a predetermined number of predetermined working positions. Thus, the cutting ability of the skewer can be increased so that the oblique _ 1GG can cut a variety of workpieces. The predetermined different working positions correspond to the maximum allowable cutting workpiece [S1 17 1354592 specifications. The maximum allowable cutting specifications of the workpiece include the maximum allowable dimension of the workpiece in the direction of the longitudinal axis 43 (ie the width of the workpiece) or the maximum allowable dimension in the direction perpendicular to the longitudinal axis 43 (ie the south of the workpiece) ). The miter saw 100 includes an indicating mechanism 9 for indicating the predetermined working positions. As shown in the third figure, the indicating mechanism 9 includes a working position mark 91 disposed on the first support member 41, and an indicator mark 92 disposed on the second support member 42 when the second support member 42 is moved to the corresponding work. In the position, the indication mark g 2 is opposite to the work position mark 91. Of course, the work position mark can also be provided on the second support member 42, and the indicator mark matched thereto is disposed on the first support member 41. The plurality of predetermined working positions are in a direction parallel to the longitudinal axis 43, and the human arrangement is 'in this embodiment, the oblique saw has three working positions'. Of course, more or more may be provided as needed. Fewer cutting positions. As shown in the second drawing, the working position mark 91 includes the first, second, and third working position marks 911, 912, and 913. The first one of the swing members 4 and the second of the second push members 5 can be made of an iron-based material. , such as cast iron or iron alloy. The use of iron-based materials increases rigidity and reduces costs. f Sj 18 1354592 The first support member 41 and the second support member 42 may be integrally formed as in the case of a conventional miter saw. Before the factory is cut off, it is necessary to align the alignment line 52 emitted by the laser generator 5 with the circular saw blade 31 in the same parallel degree, so that the operator can obtain accurate indication effect during use, so support The seat 54 is designed to be adjustable relative to the dust collector 6, or the laser generator 53 0 can be adjusted relative to the support 54. It is of course also possible to adjust the position of the dust collecting device 6 relative to the fixed shroud 33 or the supporting device 4 such that the alignment line 52 emitted by the laser generator 53 is kept at the same parallelism as the calibration of the round silver plate 31. As shown in the third figure, the miter saw 100 is in the rest position and the indicator mark 92 is aligned with the first work position mark 911, which is in the pre-determined first working position. At this point, the switch of the laser alignment device 5 is turned on, and the laser alignment device 5 produces a laser beam 51 which is projected into the cutting area, i.e., onto the workpiece 200 being cut. The laser beam 51 is projected onto the workpiece 2 to form a track alignment line 52' so that the operator can move the workpiece 2 to be cut so that the cutting mark line 210 on the alignment line aligns with the alignment line 52. Allows the operator to accurately cut the workpiece. 19 1354592 The mining mechanism 3 continues to rotate clockwise to reach the position of (4), as shown in the eighth to ninth diagrams, at which time the circular error piece 31 is rapidly rotated by the motor (9), and the workpiece 200 is cut and π i 仃 cut, At the same time, the dust collecting passage 63 and the fixed shroud 33 form a dust collecting duct β4β & mountain ^ and the sawdust and dust generated by the circular saw blade 31 during the cutting process are along the screen of the drama & _ , ^ The flow direction 39 moves and is guided into the dust collecting duct 64, and the #丹田 dust outlet 37 is discharged into the dust collecting bag. After the laser alignment device 5 is rotated in the frame, because the (4) generating device 4 is completely separated from the dust collecting duct 64, it is not adsorbed by the four (four) swarf, so that the laser aligning device 5 can be maintained. Clean. As shown in the tenth figure, at this time, the second support member 42 is moved relative to the first support member 41 / σ in the longitudinal direction 43 so that the indicator mark 92 is opposite to the third working position 913, which is obliquely The saw 1 is in a predetermined third working position. The difference from the first working position is that as the saw mechanism 3 rotates clockwise around the frame shaft 3, the dust collecting device 6 is caused to drive the laser alignment 5 and surround the second pivot 66 (such as the third The figure shows) turning clockwise; continuing to press the mining mechanism 3 until the end wall 62 of the dust collecting device 6 is in contact with the table. At this time, the dust collecting device 6 has reached the lowest limit position. Thus, the dust collecting passage of the dust collecting device 6 The inlet of the dust collecting duct 64 formed by the fixed shield 33 and the fixed shield 33 is in contact with the table and is located at the cutting groove 21. In this way, more sawdust can be collected. After the element is cut, as shown in Fig. 3, the saw mechanism 3 quickly returns to the rest position under the action of the return spring (not under the circle). During this process, the lock shaft 331 on the cover 33 of the fixed guard slid in the chute 71 until the top end of the pin 331 of the pin 331 contacts 'as shown in the sixth figure, at which time the dust collecting device 6 will Driving the laser alignment device 5 to rotate counterclockwise around the second frame axis 66, as shown in the fifth figure 'until the end wall 62 of the dust collecting device 6 is in contact with the supporting device 4, such as
