Abstract: A pneumatic tool includes: a main body; an air passage disposed in the main body for air to flow in; an air exhaustion passage disposed in the main body, one end of the air exhaustion passage communicating with the air passage, the other end of the air exhaustion passage being an air exhaustion end; a flow way disposed in the main body, a rear end of the flow way communicating with the air passage, a front end of the flow way being positioned at one end of the main body; and a control mechanism disposed in the main body and connected with the air exhaustion passage. The pneumatic tool provides both blowing and sucking effects. An operator need not replace the tool. Instead, the operator can use the pneumatic tool to blow dust or take an article.

Abstract: A pneumatic mechanism includes: a casing having a main body and a base seat; a drive mechanism disposed in the main body; a first air bypass disposed in the main body, a rear end of the first air bypass communicating with the drive mechanism; a second air bypass having a rear end positioned on the base seat; at least one airflow passage disposed on the base seat, one end of which communicating with the second air bypass; at least one sucker disposed on the base seat; and at least one air-sucking passage disposed between the base seat and the sucker. One end of the air-sucking passage communicates with the air chamber of the sucker, the other end communicates with the airflow passage. The pneumatic mechanism is powered by one single power source to operate and produce sucking force.

Abstract: A movable seat and a rail device. The movable seat includes a main body; an air passage, an air sucking passage and an air intake passage formed in the main body; a sucker disposed under bottom face of the main body and an operation/control member mounted on the main body. When the operation/control member is positioned in a locking position, the air passage or the air intake passage keeps in a communication state and make the sucker a sucking force. When the operation/control member is positioned in a releasing position, the air passage or the air intake passage is blocked. By means of easy operation, the movable seat can create sucking force and locate or stop providing sucking force. One or more movable seats can be connected with multiple beams to form the rail device, which can be quickly located or moved.

Abstract: A sucker includes: a main body having a bottom face formed with an annular abutment; a disc body made of a flexible material having a tapered annular wall, the disc body being disposed under the bottom face of the main body, an outer circumference of the annular wall being formed with a lip edge positioned below the annular contact area; an air chamber being formed in the disc body; an air-sucking passage and a fast flow way; the air-sucking passage having a first end in communication with the air chamber of the disc body and a second end passing through the disc body and the main body to communicate with the fast flow way. When the sucker sucks a surface of an object, the air in the air-sucking passage is sucked into the fast flow way.

Abstract: A sucker includes: a main body having a bottom face formed with an annular abutment; a disc body made of a flexible material having a tapered annular wall, the disc body being disposed under the bottom face of the main body, an outer circumference of the annular wall being formed with a lip edge positioned below the annular contact area; an air chamber being formed in the disc body; an air-sucking passage and a fast flow way; the air-sucking passage having a first end in communication with the air chamber of the disc body and a second end passing through the disc body and the main body to communicate with the fast flow way. When the sucker sucks a surface of an object, the air in the air-sucking passage is sucked into the fast flow way.

Abstract: A sucker includes: a main body having a bottom face formed with an annular abutment; a disc body made of a flexible material having a tapered annular wall, the disc body being disposed under the bottom face of the main body, an outer circumference of the annular wall being formed with a freely flexible lip edge positioned below the annular abutment face; an air chamber being formed in the disc body; and an air-sucking passage having a first end in communication with the air chamber of the disc body and a second end passing through the disc body and the main body to communicate with outer side. When the sucker sucks a surface of an object, the top face of the lip edge is in contact with the abutment face and supported thereby.

Abstract: A pneumatic mechanism includes: a casing having a main body and a base seat; a drive mechanism disposed in the main body; a first air bypass disposed in the main body, a rear end of the first air bypass communicating with the drive mechanism; a second air bypass having a rear end positioned on the base seat; at least one airflow passage disposed on the base seat, one end of which communicating with the second air bypass; at least one sucker disposed on the base seat; and at least one air-sucking passage disposed between the base seat and the sucker.

Abstract: A cutting tool assembly includes a mandrel member and a cutting tool. The mandrel member has a shaft rod and a slide sleeve fitted around the shaft rod. At least one alignment pin is mounted in the shaft rod and at least one engagement pin is disposed in the slide sleeve. At least one locking member is disposed between the shaft rod and the slide sleeve. The cutting tool has a shank body and a tool bit. At least one alignment sink is disposed on the shank body. When assembled, the shank body is plugged into the shaft rod to align the alignment pin with the alignment sink so as to release the slide sleeve from the engagement of the engagement pin, permitting the slide sleeve to move to a locking position where the locking member is latched with the cutting tool.

Abstract: An elliptically moving mechanism includes: a track disc formed with two tracks, the two tracks perpendicularly intersecting each other; a transmission ring rotatably fitted around a circumference of the track disc; a rocking arm positioned under the track disc; and two slide members disposed on a top face of the rocking arm. The rocking arm is connected to the two tracks via the two slide members. The two slide members are slidable along the two tracks respectively. When the transmission ring is rotated, the rocking arm is driven by the transmission ring to move in an elliptical path. The elliptically moving mechanism is easy to manufacture and assemble and has a small volume and is lightweight. Moreover, the mechanism provides different elliptical paths of different sizes.

Abstract: An axial adjustment device includes: a main body; two slide seats disposed in the main body; a first and a second threaded rods disposed in the main body and respectively screwed in the two slide seats; a first transmission gear connected with the first threaded rod; a second transmission gear connected with the second threaded rod; and a fastening member. When the fastening member is switched to a fastening position, the two threaded rods are driven with each other via the two transmission gears. When the fastening member is switched to a releasing position, the two threaded rods can be only independently rotated. The axial adjustment device can control the two slide seats to independently or synchronously move.
