A clamping device (1) for a walking pole for securing an inner tube (3) which can be slid into an opening of the clamping device that is secured to an outer tube (2). There is a plastic sleeve (4), on which a clamping lever (6) is hinged against the force of a spring element (10). The clamping lever (6) has a first lever arm (12) for releasing the clamping device (1) and a second lever arm (11) arranged on the other side. The second lever arm (11) has a protrusion (9) which is arranged radially to the pole axis (36) and which engages into and through a radial through-opening (19) in the plastic sleeve (4) and engages into a groove (22) of the inner tube (3) in a formfitting manner in order to axially secure the two tubes (2, 3).

A deformable crutch, includes a hand-held part, a seat part and a support part which are rotatably connected in sequence, and further includes a locking device for locking a rotation angle between the hand-held part and the seat part, and a rotation angle between the seat part and the support part. Rollers (34) are provided at the bottom of the deformed stool. A motor for driving the rollers (34) can also be mounted to deform the deformable crutch into an electric scooter.

An adjustable and retractable rod includes an external pipe fitting, a multi-section rod and a positioning unit. The multi-section rod includes a first and at least one second foldable rod, where the first and second foldable rods have the same outer diameter, and the positioning unit includes a linkage rope, a positioning component and a locking component, which are used to pull the external pipe fitting and the first foldable rod relative to each other. The linkage rope can be dragged, and the locking component and the positioning unit interlocked or separated. When the locking component and the positioning component are interlocked, the external pipe fitting can be connected to the multi-section rod unit in an unfolded state. When the locking component moves away from the positioning component, the first and second foldable rods of the multi-section rod are folded and in parallel relative to the external pipe fitting.

A telescoping assembly includes a first tube member, a second tube member, an inner tubular member coupled to move with said second tube member, an outer sleeve mounted on said first tube member, and a latch block disposed in a latch bore of the outer sleeve and having an actuating end region and a blocking end region. In response to pressing of the actuating end region, the latch block is displaced from a locked position, where the blocking end region is in blocking engagement with a shoulder surface of the inner tubular member, to an unlocked position.

A cane apparatus may include a body portion, a handle at a top end of the body portion, a proximity detector coupled to the body portion, an alert mechanism, and a processor communicatively coupled to the proximity detector and the alert mechanism. The processor may be configured to: determine, based on a signal received from the proximity detector, that the proximity detector is within a threshold distance of an obstacle; and based on the determination, activate the alert mechanism.
