Embodiment Construction

[0019] Such as figure 1 As shown, the special platform for all-round detection of marble traces of the present invention is generally divided into three parts: a base 5, a stand 8, and a marble rack. The number of specific settings of institutions may increase or decrease).

[0020] The base 5 plays the role of supporting and fixing, and there is a stepped protrusion in the middle, and two parallel cylindrical slide rails 6 are buried on the upper surface of the stepped raised part. The stand 8 is provided with trapezoidal lugs on both sides of the top surface of a rectangular substrate, and a section of arc-shaped hole 3 is opened on the trapezoidal lug on the right; Protective edge, the protective edge covers the front and back of the stepped protrusion of the base 5; a horizontal strip-shaped hole 9 is opened on the front protective edge, and the first set screw 10 passes through the strip-shaped hole 9, threaded in a screw hole on the base 5. The first set screw 10 can ...

Abstract

The invention relates to an omnibearing bolt trace testing special bench which is structurally characterized in that a bench frame is connected with a base in a sliding way, the two ends of the bench frame are articulated with a swing board, a plurality of bolt clamping mechanisms are arranged on the swing board, each bolt clamping mechanism comprises a dial wheel, an elastic clamp holder arranged at the top surface of the dial wheel, and a plug-in shaft which is fixedly connected with the bottom surface of the dial wheel. By using the omnibearing bolt trace testing special bench, the omnibearing bolt observation under a microscope is realized, the operation steps of a technical unlocking trace test can be simplified, operational process is standardized, working efficiency is improved, the accuracy of track test is improved, thereby facilitating criminals committing theft and promoting the social harmony and stability.

Description

technical field [0001] The invention relates to a microscope object rack, in particular to a special platform for all-round detection of marble traces. Background technique [0002] At present, domestic criminal cases of technical unlocking are relatively high, which not only cause serious harm to the property safety of the people, but also increase the workload of criminal investigation departments' technical unlocking trace inspection work. The trace inspection of technical unlocking is mainly to observe the traces on the surface of the pins in the lock cylinder under a microscope. Due to the small volume and surface area of ​​the marbles, there is no special clamping equipment at present. Therefore, when inspecting the traces of the marbles for technical unlocking, the inspectors mostly use various methods such as pinching with fingers, clamping with tweezers, or sticking with adhesive tape. to hold the bullet. These clamping methods are not only difficult to operate, b...
