The first hammer portion collided with the second hammer portion is provided integrally with one end of the impact generating hammer shaft and a handle for moving the impact generating hammer shaft is connected to the other end of the impact generating hammer shaft by a handle shaft and provided at the rear end of the housing. And the impact generating hammer shaft moved in one direction by the handle operation. When it is released, the compression spring is interposed on the outer circumferential surface of the impact-generating hammer shaft so that the first hammer part is in contact with the second hammer part to generate an impact force when the pressure is released, and a stopper is provided at the rear end of the housing so that the compression spring is not separated. Characterized in that it is mounted.

Preferably, at least one air outlet for discharging air in the housing to the outside when the first hammer portion and the second hammer portion collide with each other is formed in the housing.

Preferably, the central portion protrudes from each other so that only a part of the first hammer portion and the second hammer portion contact each other when they collide with each other.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view of a fixing ring hole perforator of the present invention, Figure 2 is a cross-sectional view of Figure 1, Figure 3a and Figure 3b is a state diagram of use of the fixing ring hole perforator of the present invention.

As shown in FIGS. 1 and 2, a blade fixing shaft 104 is formed at the tip to which the drilling blade 102 for drilling a hole of a predetermined shape is in contact with a heat insulating plate (see FIGS. 3A and 3B). And a substantially cylindrical housing 110 provided at its rear end with a handle 118 that can be reciprocated to generate an impact.

The second hammer part 112 coupled to the blade fixing shaft 104 is fixedly seated in the housing 110, and the second hammer part (reciprocating in the housing 110 according to the manipulation of the handle 118). The first hammer portion 114 is integrally formed with the impact generating hammer shaft 115 so as to collide with 112, and the handle shaft 116 for connecting the handle 118 to the other end of the impact generating hammer shaft 115 is provided. Is provided.

Here, the blade fixing shaft 104 of the perforated blade 102 and the housing 110 are each configured to be screwed so that the contact portion can be separated / combined.

In addition, the outer peripheral surface of the impact-generating hammer shaft 115 so that the first hammer portion 114 collides with the second hammer portion 112 by the elastic restoring force when the handle 118 is released after moving the handle 118 There is a compression spring 120 is interposed.

To prevent the compression spring 120 from being separated from the inside of the housing 110, the end of the housing 110 has a cap (not shown) installed to show a closed structure.

When the first hammer part 114 and the second hammer part 112 collide with each other, at least one air outlet 130 for discharging air existing therebetween to the outside is formed. In the present invention, three air outlets 130 are formed.

On the other hand, the portion of the first hammer portion 114 and the second hammer portion 112 is in close contact with each other, the center portion is formed with a protrusion (a, b portion) such that the entire surface is not in close contact with only a portion of the center portion.
