    Abstract: A screwdriver has a barrel, a screwdriver-bit assembly, and a push assembly. The screwdriver-bit assembly has a screwdriver-bit seat, multiple screwdriver-bit shafts, and multiple screwdriver-bit resilient elements. The screwdriver-bit seat is fixed in the barrel and has multiple locating holes. Each one of the screwdriver-bit shafts is slidably mounted through a respective one of the locating holes. The screwdriver-bit resilient elements abut the screwdriver-bit shafts such that the screwdriver-bit resilient elements tend to retract inside the barrel. The push assembly has an abutting mechanism, an abutting rod, and a plunger. The abutting rod is connected to the abutting mechanism and is selectively aligned with one of the screwdriver-bit shafts. A press of the plunger forces the screwdriver bit to protrude. Another press of the plunger makes the screwdriver-bit shaft retract inside the barrel and makes the abutting rod align with another one of the screwdriver-bit shafts.

    Abstract: An adjustable wrench has a handle assembly and a gripping assembly. The handle assembly includes a rotating handle, a pivot shaft, and a holding handle. The pivot shaft is securely mounted in the rotating handle, and has a right-handed screw thread and a left-handed screw thread. The holding handle is mounted around the pivot shaft. The gripping assembly includes a base, a lower jaw, an upper jaw, and a guiding module. The lower jaw engages with the left-handed screw thread of the pivot shaft. The upper jaw engages with the right-handed screw thread of the pivot shaft. The guiding module is slidably mounted through the base and the lower jaw and is securely connected to the upper jaw. By turning the rotating handle as well as the pivot shaft, the upper jaw and the lower jaw can be quickly moved to a closed state or an open state.

    Abstract: A circuit interface device includes a shell and a circuit board assembly. The circuit board assembly has a circuit board protection cap and a circuit board installed on the circuit board protection cap. A plurality of electrical connection contacts is disposed on one side surface of the circuit board. The circuit board assembly and the shell are assembled together in a structural matching mode. The circuit board is supported by the circuit board protection cap, so that the electrical connection contacts on the circuit board are corresponding to a socket at one end of the shell, and the shell enables the circuit interface device to be electrically inserted into a circuit interface jack of an electronic device by using a connecting portion.

    Abstract: An adjustable door closer has a hollow pedestal with a first and a second chamber as well as an actuating groove. An actuating device is set into the actuating groove. A first piston assembly is set into the first chamber and a second piston assembly set into the second chamber. A partition wall is formed between the first and second chambers. Due to a laterally configured flow resistance unit, the holes to be set into the first and second chambers are reduced to three, including a no connecting hole and first and second backflow bypass holes, all of which are connected only to the second chamber from the partition wall. As such, the flow path structure is simplified compared to the five holes required for typical structures. The adjustable door closer could reduce significantly the manufacturing cost and realize better regulating functions with improved applicability and economic benefits.

    Abstract: An encoding module applied to a computer input device is described, which includes an encoder and a scroll wheel. The encoder is electrically disposed on a circuit board of the computer input device and is protruded with a revolving shaft. The scroll wheel has a wheel axle passing there through and is rotatably disposed within a shell of the computer input device. One end of the wheel axle has two opposite clamping arms, so as to clamp the revolving shaft. Once the scroll wheel is rotated, the revolving shaft is driven to rotate together.
