[Prior art]

 As shown in FIG. 1, a conventional nailing machine applicable to three types of nailing standards works by inserting a nail with a nailing device 10. The nailing device 10 has an upper cover 11, and a nailing upper cover. Reference numeral 11 denotes an openable and closable work for accommodating and fixing the connecting belt 12 for nailing.

The above-mentioned nailing upper lid 11 has a storage groove 111 in the nailing upper lid 11 in order to cope with nailing of different standards, and the storage groove 111 has a nail control block 13 and a nail control belt 14. Thereby, the connection belt 12 of the nail holder having different specifications is stored and fixed.

A point to be noted here is that one end of the nail control mass 13 and the nail control belt 14 is installed in the accommodating groove 111 of the nailing upper lid 11 by the shaft portion 15, and the nail control mass 13 and the nail The other end of the control belt 14 forms a locking mechanism together with the nail cover 11 by the projections 131 and 141, and the lower side of the nail control block 13 and the nail control belt 14 generates a dent by installing the spring 16. And restore elasticity.

[0005]

[Problems to be solved by the invention]

 However, when actually used, there is a problem that the nailing does not proceed normally, and the nail may be jammed and broken. The detailed explanation is as follows. For one, the elasticity of the nail control block in the nail storage cover and the dent of the nail control belt is insufficient and uneven. One end of the nail control mass and the nail control belt are nailed by the shaft and installed on the upper lid. By the way, it cannot be used well (the traveling distance is insufficient). Therefore, the control elasticity of the nail control mass and the nail control belt is not uniform, so that the elasticity at one end (convex portion) is high and the elasticity at the other end (end at which it is installed) is low, and the nail is depressed on average. In addition to affecting nails, the nails are not positioned correctly and cannot be refilled properly.

Second, in the conventional nailing lid, there is a clear gap between the nail control mass and the nail control belt, and the overall appearance is not smooth. The connection belt waste (or iron wire) is clogged in the gap, and the nail driver breaks down.

[0007] Third, when the nail control belt of the nailing cover is mainly a short nail, the nail control belt is connected to one side of the short nail connecting belt to place the short nail in an appropriate position. When holding and using long standard nails, the nail control belt and the nail control mass are dented under pressure. It should be noted that the shape of the nail control belt and the nail control mass clearly differ, so the elastic pressure of the long nail on the connecting belt is not uniform, and there is an obstacle for the long nail to provide the nail normally. Also, clogging of nails may occur. The main purpose of the present invention is to provide a nailing machine for preventing nail clogging and applying to three kinds of nails.
