5 and 6, the handle member 100 has an upper end. 110 and the lower end 120 are fixed to the first link member 210 and the second link member 220 of the link body 200, respectively. Accordingly, when the handle member 100 is pressed, the force is pressed to the first link member 210 and the second link member 220 with the same force to rotate the pivoting body 30 (see FIG. 6). The linear motion of the bar 10 is switched. On the other hand, the connection bar 10 is mounted to improve the reliability of the link members (210, 220) interlocking. The operation of this link structure will be described in more detail in the following structure description.

7 to 11, the link body 200 includes a first link member 210 and a second link member 220 including the same components, and these link members 210 220 is the front end (10a) and the rear end (10b) of the connecting bar 10 is connected to each other organically configured.

Specifically, since the first link member 210 and the second link member 220 have the same configuration, these components will be described by taking the second link member 220 as an example.

As shown in Figs. 7 and 8, the second link member 220 is composed of a base 21, a swing cam receiving portion 22 and a swing cam 23.

The base 21 has a plurality of fastening holes 25 are formed on the upper surface, these fastening holes

Through the 25, the handle member 100 (see FIG. 6) may be coupled.

Meanwhile, as shown in FIG. 14, moving slits S2 are formed on both sides of the base 21, and curved swing slits S1 (see FIG. 8) are formed on the side surfaces of the swing cam accommodation portion 22. . Accordingly, the base 21 and the swing cam accommodating portion 22 have a first shaft (shl) inserted into the movable slit (S2) and the sun slit (S1) in the form of an overlap to form a mutual fastening.

That is, as illustrated in FIGS. 14 and 15, the bases 21a and 21b may be moved up and down along the swinging slits SI of the swinging cam receivers 22a and 22b, respectively.

Meanwhile, as shown in FIGS. 11 and 13, the swing cam 23 mounted inside the swing cam receiver 22 is mounted through the pivot shaft shO. In addition, when the first shaft (shl) penetrates through the tip of the pivoting cam (23), the pivoting cam (23) can also be linked together when the base (21) is lowered or raised. That is, the turning cam 23 is turned from the turning cam accommodating part 22 based on the turning shaft shO, and the tip of the turning cam 23 is connected to the movable slit S2 of the base 21. 1 It moves along the swing slit (S1) of the swing cam receptacle 22 along the shaft (shl).

Through this configuration, when the base 21 is pressed down and descends from the swing cam receiving portion 22, the swing cam 23 mounted inside the swing cam receiving portion 22 is also configured to interlock (turn). . In this way, the pivoting cam 23 is interlocked in the pivoting cam receiving portion 22 so that the first linking member 210 and the second linking member 220 are interlocked with each other while being spaced apart from each other. For the sake of clarity, the other end of the swing cam 23 has a configuration in which the connecting bar 10 is mounted via the second shaft _S h2.

Accordingly, the handle member 100 (see FIG. 6) is pressed so that the base 21 receives the pivoting cam receiving portion.

When descending from the 22, the swing cam 23 mounted inside the swing cam receiver 22 is pivoted along the swing slit S1 through the first shaft sl. Accordingly, the swing cams 23 on both sides connected to both sides (front end; 10a and rear end; 10b) of the connection bar 10 may ensure the interlocking operation between the first link member 210 and the second link member 220. Perform the function of interlocking each other.
