Abstract

The application discloses micrometer, including chi frame, measuring staff and control wheel subassembly, cross the micrometer focus and the cross-section of perpendicular to measuring staff axis, in the control wheel subassembly one side of this cross-section, be equipped with at least one mechanical connecting portion, this mechanical connecting portion include one of them through-hole, counter bore, screw, double-screw bolt, hasp, projection, arch and recess for connect and be suitable for wearing the pendant of finger or palm, in order to overcome the gravity of micrometer.

Description

Micrometer

Technical Field

The application belongs to the length measurement field, relates to a micrometer with connect the mechanical connecting portion who wears the pendant.

Background

The existing micrometer is not suitable for single-hand operation, but in many scenes, people still expect single-hand operation to accelerate the measurement speed. When the micrometer is operated by one hand, a part of attention of people is dispersed to the holding of the micrometer, so that the measurement precision is influenced, and the measurement efficiency is low.

Disclosure of Invention

In order to solve the problems, the application discloses a micrometer, which comprises a micrometer frame, a measuring anvil, a measuring rod, a control wheel assembly and a mechanical connecting part, wherein the mechanical connecting part is used for connecting a wearing part worn or hung on fingers or a palm so as to overcome the gravity of the micrometer; when the measuring rod is abutted to the measuring anvil, a mechanical connecting part is arranged on the ruler frame on one side of the cross-section control wheel component, and the cross-section passes through the gravity center of the micrometer and is perpendicular to the axis of the measuring rod.

The further improvement of this scheme, mechanical connecting portion include one of through-hole, counter bore, screw, double-screw bolt, hasp, arch and recess.

Advantageous effects

The pendant and the connecting part of the pendant are simple to manufacture, low in cost and easy to place, people do not need to worry about falling of the micrometer when wearing the pendant by fingers or palms, the thumb, the index finger or the middle finger is vacated to operate the control wheel assembly, attention can be used for measurement, measurement precision is improved, and measurement efficiency is improved.

Drawings

The drawings are schematic block diagrams, which are used for illustrating the principles and not for limiting the scope of the claims of the present application.

Fig. 1 is a schematic structural view of a micrometer having a mechanical connecting portion adapted to be worn on a finger or a palm.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

A micrometer comprises a micrometer frame 1, an anvil 6, a measuring rod 2 and a control wheel assembly 3, wherein when the measuring rod 2 abuts against the measuring anvil 6, a section 4 passing through the gravity center of the micrometer and perpendicular to the axis of the measuring rod 2 is arranged on one side of the control wheel assembly 3 of the section 4, at least one mechanical connecting part 5 is arranged on the micrometer frame 1 and used for connecting a wearing part or a hanging part suitable for wearing or hanging on fingers or a palm so as to overcome the gravity of the micrometer and release a thumb, an index finger or a middle finger for operating the control wheel assembly 3.

Preferably, the mechanical connection portion 5 includes one of a through hole, a counter bore, a screw hole, a stud, a catch, a boss, a protrusion, and a groove.

Preferably, the mechanical connection part 5 comprises a combination of two or more of a through hole, a counter bore, a screw hole, a stud, a lock catch, a boss, a protrusion and a groove.

Preferably, one end of the wearing piece is a closed annular soft substance, and one end of the hanging piece is a semi-closed rigid substance.

The above-described embodiment is only one aspect of the inventive idea, and other modifications obvious to those skilled in the art should be within the scope of the claims of the present invention.
