Coil spring structure for medical laboratory table

The utility model discloses a coil spring structure for a medical laboratory table, which comprises an L-shaped support plate (9). A coil spring wheel A (11) with a coil spring (6) and a coil spring wheel B (10) connected with the coil spring (6) are arranged on the L-shaped support plate (9), the coil spring B (10) is provided with a connecting rope (12), and the connecting rope (12) is connected with a clamp with a coil spring wheel C (4). Extension of an air tube is driven by the coil spring wheels, and accordingly squeezing to the air tube can be avoided while air output and service life of the air tube can be guaranteed. The air tube can be retracted by the aid of restoring force of the coil springs, and a driving device is omitted, so that the coil spring structure is simplified, failure rate is reduced, installation space is saved, and the coil spring structure is more convenient in use. In addition, the coil spring structure not only guarantees the air output and the service life of the air tube, but
