Multifunctional clamp with function of direct reading

Abstract

The technology relates to a measuring tool, and provides a linear dimension measuring tool, especially a multi-function caliper that can be read directly. , each clamp arm is a clamping segment on one side of the rotating pin, and the other side is a reading segment; at the end of the clamping segment, there is a clamp head whose angle can be adjusted within the plane determined by a pair of clamp arms and the clamp arms , the two clips with pointed front ends are symmetrically arranged. When the clip is inclined inward, it is an inner clip, and when the clip is inclined outward, it is an outer clip; in the reading section, there are also readings for reflecting the length of the inner card and the length of the outer card. The clamping section is also provided with a locking device for locking a pair of clamp arms at a certain angle; the clamping head is rotatably arranged at the end of the clamping section through the control screw, and is arranged on both sides of the rear end of the clamping head There are limit bosses for limiting the inward inclination of the chuck to the limit position and the outward inclination to the limit position.

Description

technical field [0001] This technology relates to measuring tools, and provides a linear dimension measuring tool, especially a multifunctional caliper that can be directly read. The multifunctional caliper that can be directly read can be used as an inner caliper when measuring wall thickness and other dimensions, and can be used for measuring inner hole diameters. When the size is equal, it can be used as an external caliper, and the measurement data can be read directly. Background technique [0002] In the prior art, when measuring linear dimensions such as wall thickness, inner hole diameter, and groove width of parts, inner calipers and outer calipers are often used for auxiliary measurement. After the opening of the calipers corresponds to the size to be measured, the calipers need to be removed. Using other measuring tools to measure the linear dimension of the caliper opening, the test results are affected by the skills of the inspectors, it is difficult to ensure...

Problems solved by technology

[0002] In the prior art, when measuring linear dimensions such as wall thickness, inner hole diameter, and groove width of parts, inner calipers and outer calipers are often used for auxiliary measurement. After the opening of the calipers corresponds to the size to be measured, the calipers need to be removed. Use other measuring tools to measure the linear dimension of the caliper opening. The test results are affected by the skills of the inspectors. It is difficult to ensure that the caliper opening does not change, and it is difficult to ensure the accuracy of the measurement.

In addition, the common caliper in the prior art is a single inner caliper and outer caliper, which has a single function, cannot directly read the measurement results, and cannot meet the requirements of direct and effective measurement.
