It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

As shown in fig. 1-3, the present embodiment discloses a table saw 100. The table saw 100 includes a base frame 10, a saw blade 30, a power assembly 20, and a dust collection cover 40. The top of the base frame 10 forms a table 11 for holding a workpiece. The base frame 10 also has an installation space 12 below the work table 11, and the installation space 12 is used for installing the power assembly 20 and the transmission assembly. The power assembly 20 and the transmission assembly are at least partially located in the installation space 12.

A saw blade 30 is mounted to the base frame 10 and is used to cut a workpiece. The table 11 has a through hole through which the saw blade 30 passes. At least a portion of the saw blade 30 extends from the through hole above the top surface of the table 11. The power assembly 20 and the transmission assembly drive the saw blade 30 to cut a workpiece. During the process of the saw blade 30 cutting the workpiece, chips are generated. The chips are collected by the dust collection hood 40 and discharged. Specifically, the dust collecting cover 40 is mounted to the base frame 10 and has a first chip outlet 412. At least part of the dust collection cover 40 is located in the installation space 12.

Normally, the dust collecting hood 40 collects the chips and discharges the chips from the first chip outlet 412. However, the chips are easily discharged incompletely, resulting in a part of the chips accumulating in the vicinity of the first chip outlet 412 of the dust collection cover 40.

In order to improve the chip removal effect, as shown in fig. 3 to 5, the dust collecting cover 40 of the present embodiment includes a main body cover 41 and a cover body 42, the main body cover 41 has a first chip outlet 412 and a second chip outlet 413, the second chip outlet 413 is located inside the first chip outlet 412, and the cover body 42 is movably connected to the main body cover 41 to open or close the second chip outlet 413. When the chips accumulated at the first chip outlet 412 need to be removed, the accumulated chips can be discharged through the second chip outlet 413, so that the chip discharging effect is improved.

As shown in FIG. 3, the first exhaust port 412 is a round tubular structure having a length. The first exhaust port 412 extends at least partially out of the mounting space 12.

As shown in fig. 5, in the present embodiment, the cover 42 is a flip cover, and the flip cover is rotatably mounted on the main body cover 41. Specifically, the bottom end of the cover 42 is rotatably mounted to the main body cover 41 through a rotation shaft. The shape of the cover 42 matches the shape of the second chip outlet 413 so that the cover 42 can completely close the second chip outlet 413. For example, the cover 42 and the second chip outlet 413 may be rectangular, circular, other polygonal shapes, and irregular shapes.

The extending direction of the movement space 6121 and the axial direction of the operating member 62 form an acute angle with the axial direction of the support leg 50. A stopper 64 is installed in the moving space 6121. The limiting member 64 is a shaft-like structure, for example, the limiting member 64 may be a cylindrical shaft. The two ends of the limiting member 64 extend out of the moving space 6121. The mounting assembly 60 further includes an operating member 62 that can be inserted into the socket cavity 6122. The operating member 62 can push the limiting member 64 to move in the moving space 6121.

Two oppositely disposed mounting housings 63 are coupled together and the mounting housings 63 are mounted to the base frame 10. The opposite faces of the two oppositely disposed mounting housings 63 are referred to as inner faces. The inner side surfaces of the two mounting cases 63 are respectively configured with slide grooves 631, and the slide grooves 631 extend along arcs. Both ends of the sliding groove 631 are respectively provided with a first limit groove 632 and a second limit groove 633. The first and

second limit grooves

632 and 633 are both communicated with the slide groove 631. The limiting member 64 can move in the sliding groove 631, the first limiting groove 632, and the second limiting groove 633.
