摘要： A treadmill with an anti-entrapment function allows a user to stand on the treadmill and includes a running unit, a control unit, and a sensing unit. The running unit includes two lateral bases, a driving roller, a driven roller, and a running belt. Each lateral base has a bottom end portion. The sensing unit includes a guard bar pivotally provided at the bottom end portions and at least one sensing member. When the user is accidentally pulled into the gap between the running belt and one of the lateral bases, the guard bar will be subjected to an external force and thus rotated downward about a rotation axis, thereby driving the at least one sensing member to send a warning signal to the control unit, in order for the control unit to control the rotation speed of the driving roller accordingly, lest the user be pulled deeper into the gap.

摘要： A miter saw includes a worktable and a cutting unit. The cutting unit includes a movable arm pivotably connected with the worktable, a saw blade, a triggering switch and a tilt power-off module. The movable arm defines a reference plane which intersects a working surface of the worktable at an included angle. The tilt power-off module is disposed to detect the included angle and shift the triggering switch between a power-on state and a power-off state. The triggering switch is shifted to the power-off state when the tilt power-off module detects that the included angle is less than a predetermined breaking angle so as to prevent rotation of the saw blade in a folded position for safety purposes.

摘要： A treadmill with a safety monitoring function includes a running unit and a detection unit. The running unit includes a driving roller and a running belt for a runner to stand and run thereon. The detection unit includes a sensor for detecting whether the runner exists at a predefined height on the running belt. The detection unit can be moved to change the predefined height. A safety monitoring function for a treadmill includes adjusting a height of the sensor, detecting whether the runner exists at the predefined height above the running belt, and generating a first monitoring output. Through detecting whether the runner exists at the predefined height, it determines whether the driving roller can be driven by the driving unit to prevent accidental activation by a child. Since the detection unit can be moved to change the predefined height, it allows the use by runners of different body shapes.

摘要： An elliptical trainer with incline adjustment mechanism includes a frame, a link assembly, a pedal assembly and an adjustment mechanism. The frame has a base member and a supporting member. The supporting member defines an inner space. The link assembly has two swinging arms. The pedal unit has two pedal arms. The adjusting mechanism has a shaft, a sleeve member, two coupling members, and two links corresponding to the coupling members. When the sleeve member moves along the shaft, the coupling members and the links are driven by the sleeve member, such that the pedal arms are driven to move relative to the base member. The shaft is disposed in the inner space, preventing the shaft from protruding outward. The coupling members are pivotally connected to the supporting member to evenly distribute the weight of the coupling members and the links.

摘要： A foldable miter saw with safety device includes a base unit having a working surface and an axial holder, and a cutting unit including a rotating member, a blade, a driving unit and a safety assembly that has a safety switch and a safety member. When the safety switch is not operated, the driving unit cannot drive the blade to rotate. During the period when the rotating member rotates to drive the blade from a working position to a folded position, a free end of the safety member can be rotated downward under the action of gravity, so that the safety member can rotate to an anti-touch position where the free end is relatively close to the safety switch so that the safety switch cannot be operated, and the driving unit cannot drive the blade to rotate, which can avoid accidentally touching the blade to rotate.

摘要： A saw machine placement base for holding a saw machine including a saw machine base, a saw table mounted at the saw machine base and a cutting unit pivotally connected to the saw table. The saw machine placement base includes a bottom wall, a peripheral wall intersected with the bottom wall and defining with the bottom wall an accommodation chamber, and one or multiple position clamps connected to one of the bottom wall and the peripheral wall within the accommodation chamber and adapted for clamping on the machine base of the saw machine against the peripheral wall to hold down the saw machine in the accommodation chamber. The saw machine placement base is also usable in conjunction with the saw machine as a support to extend the length of the machine base.

摘要： A tile cutter includes a base, and a cutting head assembly including a supporting arm having one end pivotally connected to the base and an opposite end connected to the saw base for enabling the cutting head assembly to be biased relative to the base and selectively positioned in a standby position, a cutting position or a received position. When shifting the cutting head assembly from the standby position to the cutting position, the supporting arm is received by a stopper to limit the cutting depth of the cutting head assembly. When shifting the cutting head assembly from the cutting position to the received position, the stopper is moved to release the supporting arm. When the cutting head assembly is shifted to the received position, a part of the saw base and the saw blade are received in a sink in the base.

摘要： A foldable miter saw includes a base unit, a worktable, a cutting unit, and a safety device. The cutting unit can be set between a working position where the saw blade and the worktable define therebetween a contained angle within 90°˜45° angle and a folded position where a stoppage signal is provided to power off the driver. The arrangement of the safety device enables a power supply to be cut off from the driver automatically when the cutting unit is moved to the folded position.
