Japanese Patent JP2019196776
Kind Code:
A
Abstract:
To provide a locking tool that is made to be reliably locked to a single pipe.SOLUTION: A locking tool 100 includes a holding part capable of holding a single pipe 200 and opened in one end, and a substantially sharp bending extension part extending from one end of the holding part with an angle to surround the other end of the holding part. The locking tool is configured such that a triangle defined by the other end of the holding part, a portion where one end of the holding part is connected with the one end of the extension part, and a portion where the extension part bends constitutes an equal equilateral triangle each other in the side length, and an opening between the other end of the extension part and the other end of the holding part where the one end comes in contact with the one end of the holding part is constituted by being narrowed into an interval of the degree enabling the column-like structure to pass. The locking tool includes a hook 400 where a pair of substantially sharp bending hook pieces inserted into an eyelet part 301 formed in an end of a protective sheet 300 and for stretching a protective sheet 300 is opposed.SELECTED DRAWING: Figure 1
