At the same time, the elastic jaw 80 supported by the fixing jaw 103 of the fixing rod 100 and the fixing protrusion 24 of the striking rod 20 is also compressed, and the elastic contacted to the tip of the striking rod 20. The tip hook 52 of the piece 50 is fixed to the locking groove 23 formed on the tip of the striking rod 20 while sliding.

And to hit the lancet (130) with the loaded striking rod 20 to pierce the needle to the blood as shown in Figure 3, as shown in Figure 3, the blow button 70 mounted on the housing 10 is the upper projection 55 Press to lower the elastic piece 50. At this time, the hook 52 of the elastic piece 50 is to be hit by the cutout portion 51 while being separated from the catching groove 23 of the striking rod 20 while advancing and hitting the lancet 130. Therefore, the needle formed in the lancet 130 is inserted into the skin and at the same time, the return spring 90 mounted on the rear end of the striking rod 20 is shot and the blood is returned by returning the striking rod 20 to its original position.

In addition, when the elastic piece 50 pressurized by the striking button 70 is lowered, the fixing piece held by the groove 53 at the rear end of the lancet integrated cap 60 mounted at the front end of the housing 10 ( 54) is also shot forward and downward while being caught by the inner surface of the lancet integrated cap 60, the elastic piece 50 does not return to the original position where the lancet is loaded so that the lancet cannot be loaded.

That is, the elastic piece 50 does not return to its original position even when the lancet integrated cap 60 is retracted from the housing 10 and the handle 40 is loaded to load the striking rod 20. Since it is in a downward state without, the hook 52 of the elastic piece 50 is not caught by the catching groove 23 of the striking rod 20, so that it is not loaded so that the used lancet 130 is not reusable. .

In order to collect blood again, the lancet integrated cap 60 attached to the housing 10 is removed, and then the lancet integrated cap 60 with the new lancet 130 is screwed onto the housing 10 by screwing. The striking rod 20 is loaded as described above by pushing back the fixed piece 54 of the elastic piece 50 in contact with the rear end of the 60. That is, when the cap 60 is mounted on the housing 10 and pushes the fixing piece 54 of the elastic piece 50, the cap 60 is supported by the recess 53.

In addition, in order to check whether the striking rod 20 is loaded, the fluorescent plate 31 formed in the connection ring 30 may be viewed through the viewing window 42 formed at the rear of the handle 40. That is, when the fluorescent plate 31 is close, it can be confirmed that it is in a loaded state, and when it is deep, it can be confirmed that it is not in a loaded state.

And in order to adjust the depth of the needle of the lancet 130 used for blood sampling is inserted into the skin, first, while adjusting the forward and reverse rotation without pulling the handle 40 mounted on the rear of the housing 10. That is, when the handle 40 is rotated forward, the handle 40 is integrally formed with the handle 40 by the toothed coupling portion 112 of the connecting rod 110 coupled with the toothed coupling portion 41 formed in front of the handle 40. Connecting rod 110 is rotated forward, reverse. When the connecting rod 110 rotates forward and backward, the guide protrusion 113 protruding into the connecting rod 110 moves along the slide groove 101 formed to be inclined on the outer circumferential surface of the fixing rod 100. An elastic protrusion 102 having elasticity on one side of the 100 is also fixed to a desired position while rotating along the unevenness 111 formed on the inner side of the connecting rod 110. At this time, the rotation of the elastic protrusions 102 along the concave-convex 111 serves to fix the connecting rod 110 while controlling by freely rotating on the outer circumferential surface of the striking rod 100 with a click.

When the knob 40 is rotated forward, the connecting rod 30 moves forward along the slide groove 101 of the fixing rod 100 to shorten the needle length of the lancet. The connecting rod 30 is moved backward along the slide groove of the fixing rod 100 to adjust the needle length of the lancet to be inserted into the skin. In addition, the needle depth adjustment of the fixing rod 100 can confirm the needle depth display mark 46 displayed on the surface of the connecting rod 30 with the confirmation window 12.
