Abstract
The application disclosed a telescopic tube assembly with limited rotation and a metal detector. The telescopic assembly includes an outer tube and an inner tube slidably connected inside the outer tube. One end of the inner tube is fixedly sleeved with a positioning ring having a sliding groove. The outer tube wall has a positioning strip extending axially, with one end extending to the outer tube end, the other end forms a rotation space with axial distance no less than positioning ring. When sliding groove matches positioning strip, the inner tube moves axially inside outer tube. When positioning ring is in the rotation space, the inner tube rotates inside the outer tube. This allows axial movement only during use to maintain angle of parts, while allowing free rotation for storage.

A telescopic tube assembly with limited rotation, comprising an outer tube and an inner tube slidably connected inside the outer tube;
- one end of the inner tube is fixedly sleeved with a positioning ring, the outer side of the positioning ring is provided with a sliding groove extending axially, and the sliding groove extends from one end of the positioning ring to the other end;
- the outer tube comprises an outer tube proximal end, an outer tube distal end, and an outer tube wall extending axially between the outer tube proximal end and the outer tube distal end, inner wall surface of the outer tube wall is provided with a positioning strip extending axially, one end of the positioning strip extends to the outer tube distal end, the other end of the positioning strip forms a rotation space with the outer tube proximal end, the axial distance of the rotation space is not less than the axial length of the positioning ring;
- when the sliding groove matches the positioning strip, the inner tube can move axially inside the outer tube;
- when the positioning ring is located in the rotation space, the inner tube can rotate inside the outer tube.
