Abstract

The invention relates to a combined optometry table. The combined optometry table comprises a chair, an optometry table and a stand column. A rocking arm is connected with the stand column. A fixed arm is fixed on a bracket of the optometry table. The fixed arm is also connected with a rocking arm. The rocking arm comprises a handle. The handle is fixed on a universal shaft. The front end of the universal shaft is connected with a fixed block by screw threads while the rear end of the universal shaft is connected with a connecting rod. The connecting rod is fixed on a universal pipe. The universal pipe is connected with a connecting block by screw threads. A supporting rod is further installed on the fixed block. An apparatus fixing bracket is installed on the supporting rod. A screw rod is further connected between the connecting block and the fixed block. A spring and a sleeve are sleeved on the screw rod. The rear end of the spring is fixed on the sleeve. An adjustable nut is arranged on the screw rod at the front end of the spring. A fixed rod is also arranged above the universal shaft, wherein the front end of the fixed rod is connected with the fixed block. A tilted block is arranged at the rear end part of the fixed rod. A cam structure is formed by the rear side of the universal shaft and the tilted block. The combined optometry table is reasonable in structure, simple and convenient to operate, safe, durable and capable of locking rapidly and accurately.
