That is, while the upper operating cover 5 is bound and coupled to the open opening of the operating body 2, the internal compression space A is closed.

At this time, while the driven rod 3 moves linearly in the compression space A, the movable rod 4 moves linearly forward and backward on the entry opening 51 of the operating cover 5.

In the rear side of the operating body 2, a guide groove 21 may be provided so that the rear end of the follower rod 3 is coupled and supported so as to move forward and backward in a straight posture while being inserted.

That is, while the lower end of the follower bar 3 is inserted into the guide groove 21, it may move forward and backward.

At the rear end of the operating body 2, a guide protrusion 22 protruding outwardly may be formed while the guide groove 21 is provided therein.

Accordingly, while reducing the space occupied by the operating body 2, it is possible to stably secure the advance and retreat movement space of the follower rod 3.

In the above, the operating cover 5 includes a cover flange 52 coupled while closing the opening of the operating body 2; It may include; a cover protrusion 53 protruding outward from the center of the cover flange 52 to form a space for linear movement of the movable rod 3 therein and having the entry opening 51 formed on the center portion. .

That is, while being assembled with the operating body 2 through the cover flange 52 and reducing the space occupied by the operating cover 5 through the cover protrusion 53, the forward and backward movement path of the movable rod 4 is reduced. In addition to securing it stably, the front end of the movable bar 4 is inserted and guided so that it can be stably moved forward and backward in a straight posture.

Accordingly, stability of operation can be secured.

At the front end of the driven rod 3 in the above, a fixing hole 31 to which a fixing pin 32 for upper fitting and fixing may be provided while penetrating from the outside to the inside of the movable rod 4 is bound.

That is, the fixing pin 32 penetrates the movable rod 4 and binds to the fixing hole 31 of the driven rod 3 so that the movable rod 4 and the driven rod 3 are detachable. can be combined

Accordingly, it is possible to secure structural stability by preventing the driven rod 3 from being separated from the movable rod 4 without permission.

The compression actuation device 1 according to the present embodiment made as described above is provided on both sides of the driven rod 3 and the movable rod 4 in the compression space A, respectively, and the driven rod 3 and As long as it is shaft-coupled to be rotatable in the direction of the movable rod 4, and a wedge-shaped stop protrusion 61 extending in the direction of the driven rod 3 and the movable rod 4 is formed at the operating end, respectively a pair of stoppers 6; Elasticity provided to connect between the stoppers 6 and the operating body 2 and to elastically press the operating ends of the stoppers 6 toward the driven rod 3 and the movable rod 4 It includes; springs (S1).

That is, the pair of stoppers 6 are axially rotated while being pressed toward the driven rod 3 by the elastic springs S1.

Accordingly, each of the stop protrusions 61 presses the driven rod 3 .

On the other hand, the compression actuation device 1 according to the present embodiment is provided on the movable rod 4 and is supported by being caught by the stop protrusions 61 of the stoppers 6 when linearly moving to the inside 421 ) And an entry end 422 having an upper inclined surface 423 formed at both ends to guide the stop protrusions 61 outward so that each of the stop protrusions 61 are opened to each other. 42);

That is, while each of the stop protrusions 61 is pressed toward the movable rod 4 by each of the elastic springs S1, it is caught on the engaging end 421 of the fixing member 42. It is supported to prevent the movable rod from being linearly moved outside without permission.

Accordingly, the movable rod 4 stably maintains its position in the compression space A at normal times.

In addition, each of the stop protrusions 61 are guided outward along the upper inclined surface 423 while the movable rod 4 is pressed by an external force and moved outward in a straight line, and rotated apart from each other.

Accordingly, a counter pressure is formed in the external force for linear movement of the movable rod 4 in the outward direction, so that the movable rod 4 moves outward slowly.

In addition, the compression actuation device 1 according to the present embodiment is coupled so that one end is guided to the driven rod 3 so that one end is blocked by the stopping step 33 formed on the driven rod 3, and the stop protrusions at both ends ( 61) outwardly so that each of the stop protrusions 61 are opened to each other; An extension spring (S2) provided between the fixed locking body 42 and the kinetic chain body 7 to form an elastic elastic pressure; includes.

That is, while the movement chain body 7 is bound through and bound to the front end of the driven rod 3, the guide movement is performed, and the range of linear motion is limited by the stopping step 33 formed on the driven rod 3.

Accordingly, between the fixed locking body 42 and the kinetic chain body 7, the elastic spring (S2) is stretched elastically.

In addition, after each of the stop protrusions 61 are opened to each other through the upper inclined surface 423 of the fixing body 42 of the movable rod 4 that moves outward by receiving an external force, the movement As the wedge body 7 approaches the lower inclined surface 71 from the outside to the inside, the stop protrusions 61 press the moving chain body 7 toward the fixing body 42 to Compression pressure is applied to the extension spring (S2).

At this time, it moves up to the maximum linear motion range to the outside for the movable rod 4 by an external force.

In addition, when the external force on the movable rod 4 is released, the kinetic chain body 7 is elastically pressed to separate from the fixing body 42 through the compressed elastic pressure of the elastic spring S2. As it is, the kinetic chain body 7 is pressed and moved in the direction of the guide groove 21 side.

Therefore, while the stop protrusions 61 are guided to the lower inclined surface 71 of the kinetic chain body 7, they rotate each other and rotate, and the elastic repulsive force according to the continuous return movement of the kinetic chain body 7 causes the As the stopping step 33 is pressed by collision, the driven rod 3 moves in the direction of the guide groove 21.

Accordingly, as the driven rod 3 coupled with the tip of the movable rod 4 moves inward at the same time, the stop protrusions 61 are positioned at both ends of the upper inclined surface 423 of the fixing body 42. spans over

Therefore, as the stop protrusions 61 approach each other through the respective elastic springs S1, an elastic pressing force is applied toward the upper inclined surface 423 to press and move the movable rod 4 inward, respectively. The stop protrusions 61 of the movable rod 4 are engaged and fixed while being caught by the catching end 421 .

Accordingly, the movable rod 4, the driven rod 3, and the stopper 6 return to their original positions.
