The invention discloses a foldable
test tube stand with high stability. The foldable
test tube stand comprises a base plate, a fixed device, a
threaded rod, a sleeve, a supporting rod, a sliding block, placing plates, an arc-shaped plate and a spring, wherein the fixed device comprises a
cylinder block, a spring, a
piston, a
piston rod and a sucking disc. The foldable
test tube stand is provided with the fixed device, due to the action of gravity, the base plate drives the
cylinder block to move downwards, the
piston moves upwards relative to the
cylinder block, the space, positioned at the lower part of the piston, inside the cylinder block is increased, and negative pressure is generated, the negative pressure is generated inside the sucking disc, and the whole test tube stand is suckedon a
desk, so that the stability of the device is greatly improved; the foldable test tube stand is provided with the
threaded rod, the sleeve, the supporting rod and the placing plates, when a test tube needs to be placed, the
threaded rod is rotated through the sucking disc, the threaded rod drives the sleeve to move upwards, the sleeve drives the ends of the placing plates to move upwards through the supporting rod until all the placing plates are unfolded, and when the test tube stand doest not need to be used, the threaded rod is rotated in opposite direction, and the placing plates can be folded, so that the space of the
desk is saved, and the operation of workers is facilitated.
