Abstract: An automatic locking guitar holding rack comprises a brace arm, a first movable lock device and a second movable lock device separated from the first movable lock device. The first movable lock device has a first movement portion located on the first holding section, and the second movable lock device has a second movement portion on the second holding section. The first and second movement portions are separated. The first movable lock device is depressible by the head of a guitar to move a first actuation member in a first compression displacement to drive a first confining member to proceed a first swivel displacement. The second movable lock device is depressible by the head of the guitar to move a second actuation member in a second compression displacement to drive a second confining member to proceed a second swivel displacement.

Abstract: A guitar holding rack with an adjustable interval comprises a first brace arm, a second brace arm corresponding to the first brace arm and an interval adjustment unit hinged between the two brace arms. The first and second brace arms have respectively a holding sections spaced from each other to form a holding space to hold the neck of a guitar and to be leaned by the guitar, and an extension section connected to the holding section and spaced from each other by an adjustment gap. The interval adjustment unit is hinged in the adjustment gap and bridges the two extension sections, and also has a first adjustment displacement in which the two holding sections are driven by extension sections inwards toward the holding space and a second adjustment displacement in which the two holding sections are driven by the extension sections outwards from the holding space.

Abstract: A tripod base with enhanced support force has a flat base and three supporting rods. The flat base has a side, a bottom surface, a tube mounting hole and three slots arranged as a triangle at the bottom surface. Each slot has an inner closed end and an outer open end that is formed through the side. Each supporting rod has a first end pivotally mounted in one corresponding slot and has an inner segment held in the corresponding slot. Because the three slots are arranged as a triangle, contact area is increased between the supporting rod and the flat base to disperse the loading to the three supporting rods, thereby enhancing the supporting force. Further, the center of gravity of the flat base is lowered because of the flat shape to prevent the tripod base from toppling over.
