Abstract: A function setting method for a control panel of an exercise equipment combines buttons of the control panel with a light source, which makes it easy for the user to tell which button needs to be pressed when the user is setting functions since the button that needs to be pressed has a turned-on backlight, namely, it turns on the button that needs to be pressed to guide the user to press, so as to reduce the possibility of pressing the wrong button and enable the user to use the control panel in a dim environment.

Abstract: A mechanical type control panel of an exercise equipment comprises a light source layer, a light-transmitting cover layer, and a film button layer, which employs the light-on button with a turned-on backlight to guide the user to press so as to reduce the possibility of pressing the wrong buttons, and also to enable the user to use the control panel to do the setting of the exercise equipment even in a dim environment. On top of that, the light-transmitting cover layer enables the light of the light emitting elements to be smoothly distributed to the buttons, so as to provide a better sense of the look of the buttons.

When the weight end is lifted by forcing a power end, the pivoted end is turned and lifted while a foot end of the second frame is lowered to rest on the ground so as to permit the tabletop bracing member to be displaced to a working position.

Abstract: A workpiece supporting device of a circular sawing machine includes a base frame for rotatably supporting a worktable and having an arcuate surface region which defines an angularly extending guiding route. A platform is disposed on and is movable along the guiding route, and has an upper mounting surface that cooperates with the worktable to support a workpiece. A tightening mechanism is displaceable between unmovable and movable positions, where the platform is brought into tight and loose engagements with the arcuate surface region. An actuator is coupled with the tightening mechanism is operable to displace the tightening mechanism. The platform is movable along the guiding route when the tightening mechanism is in the movable position such that the worktable is turnable within a relatively large angular range.

Abstract: A protective cover assembly includes a cover unit and a support plate unit. The cover unit includes an elongated hollow cover-mounting seat, two protective covers disposed on said cover-mounting seat, a positioning mechanism, and a quick release mechanism.
