摘要： A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. The drain clearing air gun additionally includes a tank at least partially positioned within the housing and including a chamber for receiving pressurized air, a motor positioned within the main body of the housing, and a pump positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. The drain clearing air gun also includes a connection mechanism coupled to the nose. The connection mechanism includes a receiving member configured to releasably couple to a plurality of accessories.

摘要： A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air. A motor is positioned within a main body of the housing, and a pump is positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. A pressure gauge is supported by the housing and includes an automatic shutoff feature. The pressure gauge is in fluid communication with the tank. When a predetermined pressure within the tank is reached the automatic shutoff feature is activated to stop the motor.

摘要： A drain cleaning machine for moving a snake in a drain includes a rotating shell, a motor to rotate the rotating shell, and a radial drive mechanism coupled for rotation with the rotating shell and including a plurality of collets. The radial drive mechanism is switchable between an engaged state in which the one or more collets move toward a snake axis to engage the snake, and a disengaged state. A translate mechanism is coupled for rotation with the rotating shell and includes a plurality of wheels. The translate mechanism is switchable between an engaged state in which the wheels move toward the snake axis to engage the snake, and a disengaged state. A selection mechanism is configured to switch the radial drive mechanism from the disengaged state to the engaged state and configured to switch the translate mechanism from the disengaged state to the engaged state.

摘要： A pipeline inspection device, including a rotatable drum housing a cable, where the cable is extendable into a pipe, a camera positioned on an end of the cable, and a hub housing electrical components of the pipeline inspection device and including a battery housing. A stand includes a mounting assembly having a first portion rotatably supporting the drum and a second portion supporting the hub within an interior of the drum, the second portion including a core, where the hub is removably coupled to the mounting assembly via the core. The hub is removably coupled to the mounting assembly by a first engagement member on the hub and a second engagement member on the core.

摘要： A drain cleaner includes a drum assembly configured to store a cable and an actuator assembly movable relative to the drum assembly between a neutral position, where the cable is free to spin and translate out of the drum assembly, an autofeed position, where the cable is allowed to spin and is automatically driven out of the drum assembly, and an autofeed locked on position, where the actuator assembly is maintained in the autofeed position without continuous input from a user. The actuator assembly includes a handle supported by the drum assembly and an autofeed locking mechanism. The autofeed locking mechanism includes a drive lock and a lock release. The drive lock engages the handle to maintain the actuator assembly in the autofeed locked on position.

摘要： A pipeline inspection device including a cable having a camera disposed on a distal end of the cable, where the camera and the cable are configured to be directed into a conduit. A first drum includes a rear wall, a front wall, and a side wall defining an interior, where the front wall has an opening providing access to the interior, and where the cable is disposed at least partially within the first drum. A stand supports the first drum, where the first drum is rotatably coupled to the stand. A hub houses electrical components of the pipeline inspection device. The hub is removably received in the interior of the first drum via the opening, where the hub is selectively removable from the first drum and insertable into an interior of a second drum.
