  The present invention relates to a piercing used to catch a suspicious person.

  Stitching is known as a tool used to catch suspicious individuals. As a piercing structure, a curved arm for catching a suspicious person is provided at the tip of a rod held by both hands. However, if the rod and arm are fixed together, the arm's rotational force is much larger than the rod's diameter when the arm is held by a suspicious person. There is a problem that the user of the thigh is shaken off and the suspicious person is missed. In order to solve this problem, there is known a piercing crotch in which a bending arm is provided so as to be rotatable around the axis of the rod with respect to the rod (for example, see Patent Document 1).

The piercing described in Patent Document 1 will be described with reference to FIGS. FIG. 6 is a front view of the pierced crotch, FIG. 7 is a partial cross-sectional view of the pierced crotch coupling device, and FIG. 8 is a cross-sectional view taken along line AA of FIG.
