Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tacker for round shots for use in driving round balls with round heads, such as concrete nails.

When driving a concrete nail, the concrete nail is usually supported with one hand and the head of the concrete nail is driven with a hammer held in the other hand. Therefore, if you drive the hammer incorrectly, there is a danger that the other hand that is supporting the concrete nail will be hit with the hammer, or that the hammered concrete nail will bounce off the front of the concrete and fly into the worker's face. The above accidents were more likely to occur in places where it was difficult to hold concrete nails by hand.

On the other hand, a tatsuka for woodworking that uses a complete mechanical method for round punching.
However, in order to accurately feed the large needles one by one below the hammer, conventional tackers make multiple rounds at equal intervals between two long pieces of tape. Either you can feed the tape intermittently by holding it in place, or you can insert a large number of circles at equal intervals near the outer periphery of a disc made of paper, etc., and rotate this disc intermittently. The large needle of the book had to be fixed in advance to either the tape '81 or a disk [2], and the lower part of the hammer was so large that it was impossible to get close to the wall.

The present invention provides a round tacker that can be loaded with a large number of large needles in bulk and feed the needles one by one, and that can also approach walls and the like.

That is, this invention provides a guide step that engages with the head of the large needle on the upper part of the opposing surface of a pair of long guide plates on the left and right sides that are inclined down m1 and face each other with a slight interval. 1
Forming a luma gasine that is slidably housed in a column, and a suppression block that is pressed against the head of the large needle in the magazine at the rear of this magazine? After iT, attach it so that it can slide freely and attach it to the nil end of the above magazine.

A pair of left and right chuck claws are provided that can be fully opened and closed, each having a gripping part that contacts the body of the large needle from the left and right sides, and an inclined stepped part that contacts the lower surface of the head of the marking round, and closes the chuck claws. This is a round punch tacker characterized by having a driving bar that is younger and thinner than the head of the large needle attached above the middle of the left and right chuck claws so as to be slidable up and down. .

Is there an English precedent for this invention below? This will be explained using drawings.
