摘要： A 3-axis parallel linear robot has three drivers disposed around a central axis and a movement mechanism. The movement mechanism has three linkage assemblies connected to an end effector in parallel. The three assemblies are respectively driven by the three drivers in a linear or rotary manner for enabling the end effector to linearly move in a three-dimensional space. Each linkage assembly has three linkage rods and three rotating joints. An inner angle defined between each rotating joint and an imaginary plane being perpendicular to the central axis is an acute angle. A first center distance between the first rotating joint and the second rotating joint is equal to a second center distance between the second rotating joint and the third rotating joint. The overall height of the movement mechanism is reduced for increasing the working stroke and for improving the movement stability of the 3-axis parallel linear robot.

摘要： A webbing length adjustment device has an outer shell, an adjustment assembly, and an elastic member. The adjustment assembly is disposed in and is moveable relative to the outer shell, and has an operating member having a lateral pressing plate portion and a sliding member moving relative to the operating member. The lateral pressing plate portion is formed on the operating member, is located above the outer shell, and is located beside the second through hole for giving more areas to exert force easily and operate conveniently. The lateral pressing plate portion is located at an outer side of a first webbing. There is no interference between the first webbing and user's hand. The elastic member is disposed in the outer shell, and is connected to the outer shell and the operating member for giving a restoring force to the operating member. The outer shell is hard to damage.

摘要： An upright two-stage dust collector includes a base unit, a suction blower unit, a filter unit and a dust collecting unit. The suction blower unit has a suction blower body. The filter unit includes a filter body, a coarse particle dust filter cartridge disposed in the filter body, and a fine particle dust filter element disposed in the coarse particle dust filter cartridge. The fine particle dust filter element is coaxially inserted in the coarse particle dust filter cartridge. The air after the first dust collection is filtered by the fine particle dust filter element to perform the second dust collection. Through the combination of the above units, in addition to a two-stage dust collecting effect, the dust collector occupies less space and can be used conveniently.

摘要： A many-to-many state identification system of equipment names broadcasted from Internet-of-Things comprises IoT nodes and IoT mobile devices connecting the IoT nodes wirelessly. Each IoT node receives the sensed value of transducer on a machine element, determining whether the sensed value of transducer is abnormal. Next, the IoT node broadcasts an equipment identification name containing an existing gateway identification code and a state code of transducer showing whether the transducer is abnormal. When the IoT mobile device scans the equipment identification name broadcasted from the IoT node, a visual interface displays the state of IoT node by identifying the gateway identification code and the state code. Accordingly, before connecting the IoT mobile device to the IoT node, the state of transducer in the IoT node is acquired, allowing any IoT mobile device to monitor any transducer in a synchronous and many-to-many manner within the broadcasting area.

摘要： A ratchet seat, a ratchet tool head, and a bidirectional ratchet hand tool are disclosed. A handle unit includes an annular groove and a cavity. A positioning ring is stretchably disposed in the annular groove. A first actuating unit and a second actuating unit are elastically placed one over another in the cavity. An outer peripheral surface of a ratchet seat forms a ratchet toothed portion and a positioning groove. The ratchet seat is movable between a first position and a second position in an up-down direction. When the first position is assumed, the positioning groove is slidably moved to engage with the positioning ring, and the first actuating unit meshes with the ratchet toothed portion. When the second position is assumed, the positioning groove disengages from the positioning ring, and the second actuating unit meshes with the ratchet toothed portion.
