  • Patent number: 11174925
    Abstract: A dual-shaft driving module includes two shafts and a synchronizing block sandwiched between the two shafts. The two shafts are substantially parallel to each other and are substantially in a mirror symmetrical arrangement. Each shaft has two spiral grooves recessed on an outer surface thereof, and each spiral groove has a spiral angle within a range of 40 degrees to 60 degrees. The synchronizing block includes two concave surfaces arranged on two opposite sides thereof and four driving portions respectively protruding from the two concave surfaces. The two concave surfaces respectively face the two shafts, and each concave surface accommodates a part of the corresponding shaft. The four driving portions are respectively inserted into the four spiral grooves. When one of the two shafts is spun to transmit a force to the synchronizing block, the synchronizing block rotates the other shaft at the same time by the force.

    Abstract: A hand-held power tool includes a motor-driven percussion mechanism. The percussion mechanism includes a guide tube (21) and a reciprocating driving member (22) displaceable in the guide tube (21) for driving, via a gas spring, an impact member (23) likewise displaceable in the guide tube (21). The percussion mechanism further includes a motor-driven eccentric wheel (17) rotatable about an axis (D) which is spaced from the percussion mechanism axis (S) in a direction perpendicular to the percussion mechanism axis (S) by a distance (X). A connection rod (29) is eccentrically supported on the eccentric wheel (17) and connected to the driving member (22) for converting a rotational movement of the eccentric wheel (17) into a reciprocating movement of the driving member (22).

  • Publication number: 20110115577
    Abstract: A linear actuator includes a drive arm and an extension arm each extending along a common drive axis. One of the arms has a plurality of resiliently deformable fingers extending beyond the end of the arm towards the other arm. At least one of the fingers has a thread on its inner face while the other arm has a threaded portion. At least part of the threaded portion is received between the fingers. The fingers are adapted to urge the threads of the two arms into interengagement such that rotation of the drive arm about the drive axis displaces the extension arm along the drive axis. The two threads are arranged such that when the ridge of one thread is received in the groove of the other thread the two sides of the ridge abut the two edges of the mouth of the groove.

  • Patent number: 7895999
    Abstract: In one aspect the invention discloses a gas cooktop which is relatively easy to clean and which is not visually complex. The gas cooktop surface is provided with a trivet having two operating conditions. In a first condition the trivet is retracted and is substantially flush with the cooktop surface. In a second condition the trivet is extended to support a cooking vessel above a gas burner. In another aspect the invention discloses an improved gas burner with a high turn-down ratio. The improved burner includes first and second gas flow passages, a flame front locator, in one of the passages and a burner head. Fuel gas is injected into an end of one of said passages and is ignited to establish a flame at the flame front locator. Secondary combustion air is provided through the other of the passages which on a high setting enables secondary combustion and on a low setting may mix with the hot gases and cool them resulting in a lower temperature at the cooking vessel.
