Detailed explanations and technical contents related to the present invention will be described together with diagrams.

FIG. 1 and FIG. 2 are a three-dimensional external view and a schematic exploded view as a preferred embodiment of the present invention. As shown in the figure, this embodiment includes a main body 10, an elastic element 20, and a pushing element 30, and the structure will be described below. Among them, the main body 10 is provided with a storage space, and an elastic element 20 that receives biasing elasticity is installed in the storage space, and the push element that abuts the elastic element 20 on the main body 10 and moves the storage space up and down. The pushing element 30 includes a positioning portion 36 that contacts the elastic element 20, the side wall of the storage space of the main body 10 faces the side surface of the pushing element 30, the rail groove 11 and the guide portion 31. The push element 30 slides within the storage space of the main body 10 using the guide portion 31 and the rail groove 11, and the push element 30 integrally forms a flexible limited arm 32, The main body 10 is provided with a trajectory section 40 that is a movement path of the limited arm 32 corresponding to the vertical movement path of the push element 30, and a limiting section 41 is installed in the trajectory section 40. The limiting portion 41 protrudes from the trajectory section 40 and has a height, and the limiting arm 32 has a limiting end 321 corresponding to the height and limited to the limiting section 41, and the main body 10 has the trajectory section 40. The side surface located at is an open surface, and a cover 12 is disposed on the open surface. The cover 12 and the main body 10 face each other, and the fixed convex portion 121 and the fixed hole 13 are installed.

FIG. 5 is another external schematic diagram of the present invention. The push element 30 further includes a lower portion 33 that abuts the elastic element 20, and a connecting plate having flexibility at an inclination angle integrally with the end portion of the lower portion 33. 34 is extended, and the positioning part 36 which contacts the upper part 35 of the said lower part 33 and the said elastic element 20 using the connection board 34 is connected. The lower portion 33 and the upper portion 35 are opened at the start position, and when the pushing element 30 moves in the main body 10, the upper portion 35 approaches the lower portion 33 around the connection plate 34 and is closed, and has a clamp section.

  4A to 4C are application diagrams showing a preferred embodiment of the present invention. When the hook A is propelled along the path P toward the lower portion 33 of the pushing element 30 and comes into contact with the lower portion 33, FIG. 30 moves to the bottom end of the body 10. As the push element 30 continues to move on the bottom end of the main body 10, the upper part 35 retracts into the storage space of the main body 10, closes to the lower part 33, and has a clamping space.

  3A to 3E and FIGS. 4A to 4C are a schematic diagram and an application example of a continuous operation which is a preferred embodiment of the present invention. The push element 30 uses the guide portion 31 and the rail groove 11 to make the main body 10. When the push element 30 slides in the storage space of the main body 10, the limiting portion 41 protrudes from the locus section 40 and has a height, and the limiting arm 32 corresponds to the height. The limiting portion 321 is limited to the limiting portion 41, and the limiting end 321 defines the movement path of the push element 30 and the limiting arm 32 according to the geometrical shape of the locus section 40 and the limiting portion 41. When the push element 30 and the retracting arm 32 are in the start position (see FIGS. 3A and 4A), the lower portion 33 and the upper portion 35 are opened. A force is applied to the push element 30 and the limiting arm 32 to move to the first-step downward direction forcible push position, and the upper portion 35 retracts into the main body 10 and approaches the lower portion 33 (see FIG. 4B). When the directional forced pushing position is reached, the lower portion 33 and the upper portion 35 are closed (see FIG. 3B), and when the applied force is released, the limiting end 321 causes the pressing element 30 and the limiting arm 32 to move together due to the geometric shape of the limiting portion 41. The elastic element 20 is moved by the thrust generated and positioned at the pressing position (see FIGS. 3C and 4C), and the lower portion 33 and the upper portion 35 are closed and have a clamp space. The force is applied again to press the pressing element 30 and the limiting arm 32 away from the position, move to the second-stage downward forced pressing position (see FIG. 3D), and the applied force is released. Due to the geometric shape, the pushing element 30 is moved in the direction of the starting position by the thrust provided by the elastic element 20, the upper part 35 slides the main body 10, and the lower part 33 exhibits a pulling-out action (see FIG. 3E).

FIG. 6 is an exploded schematic view showing another preferred embodiment of the present invention. The push element 30a of the multistage push switch can be a switch type button.

  FIG. 7 is a schematic diagram of the appearance of another preferred embodiment of the present invention. The main implementation method has been described above, and the main body 10b has an open surface for moving the push element 30b up and down. In addition, the main body 10b is located at the open surface portion, and a rail 14 and a guide groove 37 are installed facing the side surface of the push element 30b, and a stopper 141 for limiting the lower portion 33 is provided at the upper end of the rail 14. The first pressing element 30b moves up and down in the storage space of the main body 10b using the guide groove 37 and the rail 14, and the stopper 141 presses the upper edge of the lower portion 33, thereby pressing the pressing element 30b. The main body 10b is not detached from the storage space.
