The fixing member 10 is fixedly coupled to the human body or a part of the human body, for example, a trunk part of a user such as an arm, by means of a band. Accordingly, two strap attaching holes 121 for fixedly attaching both ends of the strap are provided on the fixing member 10, respectively, so that the fixing mechanism 10 is attached to the body or a portion of the body of the user through the strap attached to the strap attaching holes 121.

In some embodiments, the fixing mechanism 10 is formed to have substantially the same shape as the external shape of the human body or a part of the human body, so that the fixing member 10 can be integrally attached to the human body or a part of the human body. Preferably, the fixing mechanism 10 is formed in an arc shape substantially the same as the shape of the arm.

At least two abutting parts 22 of the abutting members 20 are arranged on the supporting column 21, and the at least two abutting parts 22 extend in the radial direction of the supporting column 21 to protrude from the supporting column 21. the rotating member 30 is arranged between the abutting parts 22 and the fixed member 10 in a limited manner, and the rotating member 30 can rotate around the supporting column 21 in a reciprocating manner between an initial position C and a final position L. in other words, the abutting parts 22 and the fixed member 10 are arranged at intervals to form a space capable of accommodating the rotating member 30, and the space satisfies the size of the rotating member 30 which can smoothly rotate around the supporting column 21 in a reciprocating manner between the initial position C and the final position L.

In this embodiment, the abutting member 20 further includes a limiting plate 23, the limiting plate 23 is disposed at an end of the supporting column 21, the at least two abutting portions 22 are disposed on the limiting plate 23, the abutting portions extend to a circumferential periphery of the limiting plate 23, the circumferential periphery of the limiting plate 23 is a radial direction of the supporting column 21, the limiting plate 23 is spaced from the fixed member 10, that is, the rotating member 30 in this application is disposed between the limiting plate 23 and the fixed member 10, and the limiting plate 23 is spaced from the fixed member 10 to form a space capable of accommodating the rotating member 30, and the space also satisfies a size that the rotating member 30 can smoothly rotate around the supporting column 21 in a reciprocating manner between the initial position C and the final position L.

As shown in fig. 1 and 4, the retaining member 40 has a hook, the opening 422 of the hook faces the supporting column 21, and in the retaining state, the retaining member 40 swings towards the supporting column 21 to reduce the distance between the openings 422 and retain the object to be fixed, i.e., the retaining member 40 swings towards the gathering direction to retain the object to be fixed. In the released state, the holding members 40 swing toward each other in a direction away from the supporting column 21 to increase the distance between the openings 422, i.e., the holding members 40 swing in an expanding direction to release the objects to be fixed. More specifically, the opening 422 is held in a converging manner and held in an open manner toward the holding member 40 of the support column 21.

Of course, in other embodiments, if the opening 422 of the hook faces away from the supporting column 21, in the holding state, the holding member 40 swings towards the direction away from the supporting column 21 to increase the distance between the openings 422 to hold the object to be fixed, i.e., the holding member 40 swings towards the expanding direction to hold the object to be fixed. In the released state, the holding members 40 swing toward the supporting column 21 and toward each other to reduce the distance between the openings 422, i.e., the holding members 40 swing in the converging direction to release the object.
