<p>PROBLEM TO BE SOLVED: To improve sample recovery efficiency by preventing injury of an operator and preventing falling of a sample collection bag irrespective of an operator's skill level by a simple method during ore sample collection work.SOLUTION: A sample collection bag holder is constructed such that one wire material is symmetrically folded and formed into a roughly 8 shape including two continuous circular arc parts, the first circular arc part of the two continuous circular arc parts is expanded greatly away from the longitudinal center line of the roughly 8 shape with a predetermined length symmetrically from a peak part and folded toward the center line to be a sample bag fitting part, and the second circular arc part adjacent to the first circular arc part intersects the tail end of the first circular arc part on the center line to form an intersection part, thinly expanded to be gripped by hand from the center line and folded toward the center line, and has its both ends connected to a lowest part to form a grip part.</p> |
