A circular pressing portion 240A formed by disposing the first and second fixing wires 241 and 242 in opposite directions is formed in each fitting hole 211,

A neck portion 120 inserted into the fitting hole 211 is inserted into the circular pressing portion 240A.

Both ends of the first and second fixing wires 241 and 242 are exposed to the outside through a screw hole 213 formed in one side of the upper powder 210.

The tightening member 243 can be tightened or loosened at the screw hole 213 of the upper powder 210,

A tubular body portion 243A screwed to the screw hole 213 and a grip portion 243B connected to one end of the tubular body portion 243A,

The tubular portion 243A includes a through hole 243a formed to penetrate along the central longitudinal direction and an exposure hole 243b formed in the lateral direction and communicating with the through hole 243a.

At this time, both ends of the first and second fixing wires 241 and 242 are passed through the through hole 243a, And exposed to the exposure hole 243b to be fixed and coupled to the outer periphery of the tubular body 243A or the grip portion 243B.

Therefore, when the user grips the grip portion 243B and rotates in one direction to tighten the tightening member 243 in a state where the upper and lower powder 210 and 220 are combined with the ampule set 100S, The first and second fixing wires 241 and 242 that are passed through the fitting holes 211 in a staggered manner as the first and second fixing wires 241 and 242 are wound around the tubular portion 243A 242 are reduced in length and the circular pressing portion 240A disposed in each fitting hole 211 is tightened to press both side surfaces of the neck portion 120 inserted in the fitting hole 211,

When the user holds the grip portion 243B and rotates in the other direction to unwind the fastening member 243, the first and second fixing wires 241 and 242 wound on the tubular portion 243A are returned to their original positions, The pressurizing portion 240A is opened and the neck portion 120 inserted into the fitting hole 211 can be separated.

If the first and second fixing wires 241 and 242 are wound when the fastening member 243 is screwed in a general screw direction (i.e., a right-handed screw), the grip portion 243B and the upper powder 210, So that it interferes with the winding of the fixed wires,

If the threaded portion of the tubular portion 243A is formed in a direction opposite to the general thread direction (i.e., the left threaded portion), the fastening members 243 are loosened in the clockwise direction, It is more preferable to wind it around.

In this case, the first and second fixing wires 241 and 242 are wound around the first and second fixing wires 241 and 242 so as to facilitate winding of the first and second fixing wires 241 and 242 and recovery of the first and second fixing wires 241 and 242, 241) 242 includes twisted portions 241a, 242a that allow a portion of the end portion to be twisted in a helical shape so as to be wound or unwound around the outer periphery of the tubular portion 243A.

The first and second fixing wires 241 and 242 are made of a steel wire having a predetermined rigidity and elasticity (for example, austenitic stainless steel such as SUS 304), and the fastening member 243 is loosened So that the twist portions 241a and 242a can be restored to the original shape.

If the thickness of the first and second fixing wires 241 and 242 is too thin or the material used is too soft, the first and second fixing wires 240 and 242, which form the circular pressing portion 240A in the fitting hole 211, The fixing wires 241 and 242 may not be sagged, and the restoring widening may not occur when the tightening member 243 is loosened.

The present invention is connected to the first fixing wire 241 or the second fixing wire 242 having one end connected to the inner circumference of the fitting hole 211 and the other end forming the circular pressing portion 240A, And a pair of elastic members 244 exerting an elastic force in a direction in which the elastic member 240A is extended.

When the elastic body 244 having the above-described configuration is inserted between the fitting hole 211 and the first and second fixing wires 241 and 242, when the fixing wires are loosened in the fastening member 243, The circular pressing portion 240A is pressed by the elastic force of the first and second fixing wires 241 and 242 so that the first and second fixing wires 241 and 242 return to their original positions,

At the same time, since the circular pressing portion 240A is always pressed by the elastic force of the elastic body 244, the space through which the neck portion 120 can pass can be secured.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited thereto. Various modifications, alterations, and substitutions may be made by those skilled in the art. Should be construed as falling within the scope of protection of the present invention.
