When the button part (L21a) is released, the release block (L22) It is pushed to the other side. In addition, in order to realize such an operation process, the release block L22 has a slope corresponding to the shape of the actuator L21b and has a slope with an upper end in contact with the lower end of the actuator L21b.

Next, the locking means includes a release part for releasing the coupling of the locking part and the locking part by pressing the button block L21, and this release part includes the above-described actuator L21b and a release block L22, As will be described later, as the release block L22 is moved to one side by the lowering of the button block L21, the combined state may be released.

And the unlocking portion of the locking means includes a push block (L25) provided to be partially exposed to the upper portion of the movable surface on which the release block (L22) moves, wherein the movable surface is a base upper end (L20c) and a base lower end (L20b) Means the interface of. And the push block (L25) is exposed to the upper part of the movable surface when the release block (L22) is moved to one side by the lowering of the button block (L21), the release block (L22) by the rise of the button block (L21). When it moves to the other side, it is built into the inside of the movable surface. And in order for the release block (L22) to be moved by the push block (L25) on the movable surface, a return means including a spring coupled to the outside of one end should be provided, and as shown in FIG. 7, the release block ( A first spring (L24) is provided as a return means provided on the outer surface of one end of L22).

Next, the locking means is provided at the other end of the base, and includes a locking part to be described later, and a locking part that is coupled, wherein the upper end of the locking part contacts the lower end of the push block L25, and the push It includes a locking pin (L26) that can be moved to the other end side by the lowering of the block (L25). One end of this locking pin (L26) has a downward slope toward one side, so that it can be moved to the other side by the lowering of the push block (L25), as described above. ). (Of course, in this case, the button block L21 rises upward, and this is a situation in which the release block L22 moves to the other side.) And the locking pin L26 It includes a locking pin (L261) that is built in the other side and protrudes to the side of the locking pin (L26), such a locking pin (L261) is inserted into the locking groove (L111) to be described later, the locking part and the locking part can be combined. There will be. And the side here means the direction through which FIG. 7 comes out, and the other side which will be described later means the direction through which FIG. 7 enters.

In addition, a return means including a spring or the like is provided on the outer surface of one end of the locking pin L26, so that when the push block L25 is raised again, the coupling state can be released by returning to the original position. And in this release process, first, the locking pin (L261) must be able to escape from the locking groove (L111), which is the elastic force of the spring coupled to the outer surface of one side of the locking pin (L26) is the locking pin (L261) It is realized by being provided stronger than the elastic force of the spring coupled to the outer surface of the other side. And, as shown in Figure 7, a second spring (L262) is provided as a return means provided on the outer surface of one end of the locking pin (L26), as a return means provided on the inner surface of the other side of the locking pin (L261) A third spring L263 is provided.

Therefore, when the user presses the button part (L21a) when the user wants to release the combined state, the button block (L21) descends and the release block (L22) moves to one side, and the release block (L22) moves to one side. As the push block (L25) built in the bottom (L20b) rises, the locking pin (L26) exits the locking groove (L111) and the locking pin (L26) exits the entry hop (L11) and the coupling is released. It can be. In addition, in order to create a combined state, the user can press the side cover L10a to the base while pressing the button L21a and then release the pressed button L21a. It is realized by moving the configurations in reverse.

Then, as described above, the first housing L1 includes an upper cover L10b having a binding hole at one end, and the button block L21 can be inserted into the binding hole.

And the first housing (L1) includes a side cover (L10a) that is rotatably connected downward from the other end of the upper cover (L10b), obviously, in order for the side cover (L10a) to be rotatably connected, It should be rotationally coupled with a rotation means provided at the other end of the upper cover (L10b). And, for such a rotating means, there is no need to be limited to a specific embodiment, and any configuration capable of providing a rotating coupling may be used.

Next, the side cover (L10a) includes a locking portion at the lower end, and as described above, the locking portion has an entry groove (L11) opened to the other side so that the locking pin (L26) of the locking portion can be inserted and the locking pin (L261). ) Includes a locking groove (L111) formed on the inner side of the entry groove (L11) to be inserted. And obviously, these entry grooves (L11) and locking grooves (L111) each have a shape corresponding to the shape of the locking pin (L26) and the locking pin (L261), as described above, the locking part and the locking part are engaged/disengaged. It can be.

The present invention described above with reference to the accompanying drawings can be variously modified and changed by a person skilled in the art, and such modifications and changes should be construed as being included in the scope of the present invention.
