The invention discloses a special convenient-to-demount screw for instruments and meters. The special convenient-to-demount screw comprises a screw stem, the bottom end of the screw stem is provided with a sharp screw apex, the top end of the screw stem is provided with a dust storage chamber, a reinforcing disc is arranged above the dust storage chamber, an upper reinforcing part is arranged above the reinforcing disc, and an auxiliary demounting device is arranged on the upper surface of the upper reinforcing part. An internal connection reinforcing part is connected to the bottom end of theauxiliary demounting device, and an external blade is arranged on the lateral side of the top of the screw stem. The auxiliary demounting device comprises a labor-saving screw rod and a screw connector, the top of the labor-saving screw rod is provided with a rotating screw head, the surface of the rotating screw head is provided with a cross-shaped notch, a stereo threaded device is arranged onthe surface of the labor-saving screw rod, and the inner surface of the screw connector is provided with a groove thread. By structural arrangement of the dust storage chamber and the auxiliary demounting device, problems of dust generated in use of an existing screw and failure in easy demounting are solved.
Description
technical field [0001] The invention relates to the technical field of hardware products, in particular to a special screw for easy disassembly of instruments and meters. Background technique [0002] Screw is one of the most commonly used fastening parts, and it is used in many fields such as mechanical engineering, electrical equipment, medical equipment, etc. The common screw in the prior art consists of a screw head with a groove and a cylindrical or conical screw with a thread. The metal screw rod is composed of a metal screw rod, and the screw head and the screw rod are usually set as one, and a screwdriver is inserted into the groove to turn the screw head to drive the rotation of the screw rod. [0003] For example, the application number is 201620430914.6, and the name is a screw invention patent: [0004] The invention provides a screw, comprising: a screw rod, the screw rod is provided with threads; a nut, the nut is connected with one end of the screw rod; One-...
