ABSTRACT:
An adjustable supporting bracket which includes a supporting arm, an anchoring base and a supporting bracket is provided. A linkage is attached to the lower end of the gas cylinder (or spring member). The linkage is provided with a pair of sliding shafts which in turn are slidably received within a pair of corresponding grooves disposed under the supporting arm. The linkage is provided with a threaded socket at the rear central portion. An adjusting bolt is disposed with the threaded socket. A coil spring member is enveloped at the bolt and disposed located between the bolt head and the threaded socket. By this arrangement, the threads are prevented from being readily worn out while the bolt can be rotated smoothly.
