Claims19
A locking mechanism for connecting a connection assembly and a support assembly of a detachable support, the support assembly comprising a main body provided with a sleeve having a positioning part, and the connection assembly comprising a first telescopic rod, wherein:
- the locking mechanism comprises a drive part and a movable part connected to each other, the movable part has a protrusion, wherein the movable part is detachably connected to the first telescopic rod and the main body;
- wherein the locking mechanism has a locked state and an unlocked state:
- in the locked state, the movable part prevents the first telescopic rod and the main body from axially disengaging from the movable part along the first telescopic rod, and the drive part prevents the movable part from disengaging from the first telescopic rod or the main body;
- and
- in the unlocked state, the movable part disengages from the first telescopic rod and/or the main body;
- wherein a top of the protrusion of the movable part is provided with a boss pin, the boss pin being configured to:
- in the locked state, be embedded into the positioning part of the sleeve of the main body to enhance engagement stability;
- in the unlocked state, disengage from the positioning part to allow movement of the movable part.
A detachable support, comprising a connection assembly comprising a first telescopic rod and a support assembly comprising a main body, and further comprising a locking mechanism for connecting the support assembly and the connection assembly, wherein:
- the locking mechanism comprises a drive part and a movable part connected to each other, wherein the movable part is detachably connected to the first telescopic rod and the main body,
- wherein the locking mechanism has a locked state and an unlocked state:
- in the locked state, the movable part prevents the first telescopic rod and the main body from axially disengaging from the movable part axially along the first telescopic rod, and the drive part prevents the movable part from disengaging from the first telescopic rod or the main body;
- and
- in the unlocked state, the movable part disengages from the first telescopic rod and/or the main body;
- wherein the support assembly further comprises a balance adjustment part disposed at a lower portion of the main body;
- and
- the balance adjustment part comprises an internal thread and a matching nut, an axis of the internal thread extends vertically and is parallel to a central line of the main body, and a height of a corresponding side of the main body is adjusted by rotating the matching nut.
A detachable support, comprising a connection assembly comprising a first telescopic rod and a support assembly comprising a main body, and further comprising a locking mechanism for connecting the support assembly and the connection assembly, wherein:
- the locking mechanism comprises a drive part and a movable part connected to each other, wherein the movable part is detachably connected to the first telescopic rod and the main body,
- wherein the locking mechanism has a locked state and an unlocked state:
- in the locked state, the movable part prevents the first telescopic rod and the main body from axially disengaging from the movable part axially along the first telescopic rod, and the drive part prevents the movable part from disengaging from the first telescopic rod or the main body;
- and
- in the unlocked state, the movable part disengages from the first telescopic rod and/or the main body;
- further comprising a drive rod and an end cap, the drive part being fixedly connected to the movable part through the drive rod, and a rotation channel being provided in the end cap, wherein the drive rod is rotatably arranged within the rotation channel of the end cap, a first connecting end of the first telescopic rod is fixedly connected to the end cap, and the rotation channel of the end cap extends axially along the first telescopic rod;
- wherein the first connecting end of the first telescopic rod has a first through hole, the movable part has a protrusion, and in the locked state, the protrusion extends out from the first through hole;
- and
- the main body is provided with a sleeve, the sleeve has a positioning part corresponding to the first through hole, and in the locked state, the protrusion is engaged with the positioning part, and the positioning part prevents the movable part from disengaging from the main body;
- wherein the sleeve has a positioning through hole, in the locked state, the protrusion of the movable part extends out from the first through hole and the positioning through hole.
