Abstract: A reciprocating conveyor includes a first carrier that is slidably mounted on a first sliding rail mechanism, a sliding seat that is slidably mounted on a second sliding rail mechanism and that is situated below the first carrier, and a second carrier that is connected to the sliding seat, that is movable upwardly and downwardly relative to sliding seat, and that has a slide protrusion slidably engaging with a guiding rail. When the first and second carriers are respectively at a first location and a second location, the second carrier is movable through a dodging location that is lower than the first and second locations, via sliding engagement between the slide protrusion and the guiding rail, to the first location, thereby driving the first carrier to simultaneously move, via a linkage unit, to the second location.

Abstract: A container feeding device includes a casing and first and second latch members. The casing defines a lower retaining space for receiving a plurality of containers that are stacked on one another. The first latch member is operable to enter the lower retaining space for supporting a bottommost container, or leave the lower retaining space to release the bottommost container. The second latch member enters the lower retaining space to support a second bottommost container when the bottommost container is released by the first latch member.

Abstract: A tool set includes a tool holder, a tool and a tool rack. The tool has a groove unit. The tool holder has a latch unit that engages the groove unit. The tool rack includes a rack body and a blocking member. When the tool holder is moved away from the rack body after the tool is moved into the rack body by the tool holder and after the blocking member moves to a blocking position, the tool is blocked by the blocking member so that the latch unit is separated from the groove unit and that the tool holder is separated from the tool.

Abstract: A mounting frame for being mounted with either one of first and second screwdrivers, includes a main frame, a mounting seat, and first and second mounting plates. The mounting seat has a plate attachment hole set. The first mounting plate has a first seat attachment hole set operable to be connected to the plate attachment hole set, and a first driver attachment hole set for the first screwdriver to be attached thereto. The second mounting plate has a second seat attachment hole set operable to be connected to the plate attachment hole set, and a second driver attachment hole set for the second screwdriver to be attached thereto.

Abstract: Provided is an underground pipe leak detection system, including a sensing device, a storage device, and a processing device. The sensing device is used for collecting a voice signal from an underground pipe during a time period. The storage device is used for storing a voice dataset, and storing the voice signal transmitted by the sensing device. The processing device may access the storage device. The processing device is configured to execute the following operations: training a classification model using the voice dataset; extracting features of the voice signal; inputting the features of the voice signal into the classification model that has been trained to determine if there is a leak in the underground pipe.
