The melon seed pieces 6 are commercially available parts, and are formed by three melon seed-shaped steel claw pieces which are arranged into a conical body and are plugged into a conical inner cavity of the inner bushing 5, wherein the melon seed pieces 6 with half length can penetrate through the holes of the inner bushing 5 and are exposed outside.

In an embodiment of the present application, please refer to fig. 3, wherein fig. 3-a is a cross-sectional view of a central shaft 3, fig. 3-B is a perspective view of the central shaft 3, the central shaft 3 is a section of cylinder, one end of which is provided with a first internal thread 18 of M8, and the other end of which is provided with a second internal thread 19 of M10, and is in threaded connection with a pulling nut head 15 in a pulling and riveting nut assembly 22; at the end of the second female thread 19, a male thread of M14 is also provided, which is connected to the inner bush 5.

The utility model discloses in the embodiment of application, door closure 9 is a little section screw thread section, and the specification is ordinary tooth M14 x 1, door closure 9 is equipped with the through-hole, and the aperture is 9mm, and spring 8's external diameter is 8mm, can let spring 8 pass, and door closure 9 has certain spacing usefulness to spring 8, can not let spring 8 have and rock. The rear end face of the melon seed sheet 6 is supported by a top pin 7 provided with a spring 8, a through hole is formed in the center of the top pin 7, and then the melon seed sheet is screwed into the internal thread hole of the inner bushing 5 by a door cover 9 (the melon seed sheet is screwed to about half thread stroke).

In an embodiment of the application, the center of knock pin 7 is equipped with the through-hole, and the through-hole is used for passing the long pull rod of treating riveted rivet.

In the embodiment of the present invention, an external thread is provided at one end of the guide nozzle 11, and the external thread is M10, and is connected and fixed with the internal thread end of the connecting casing 10; the center of the guide nozzle 11 is provided with a through hole, and the through hole is provided with an internal thread M6 for connecting and fixing with an external thread M6 of the blind rivet head 12.

In the embodiment of the present invention, the outer sleeve 10 is provided with an external thread M20 at one end, which is connected and fixed with an internal thread M20 at one end of the middle sleeve 1.

Referring to fig. 8, a conical melon seed piece 6 is placed in a conical inner cavity of an inner bushing 5, and is supported by a top pin 7 with a spring 8, a door cover 9 is screwed into an internal thread of the inner bushing 5, and then the inner bushing 5 is screwed and fixed with an external thread 20 of a central shaft 3; then the external thread of the connecting outer sleeve 10 is screwed into the internal thread end of the middle sleeve 1, the external thread of the guide nozzle 11 is screwed into the internal thread of the connecting outer sleeve 10, and the external thread of the pull nail head 12 is screwed into the internal thread of the guide nozzle 11, so that a set of pull rivet assembly 21 is formed.

In the blind rivet gun head for blind rivets provided in this embodiment, in normal use, the blind rivet nut assembly 22 is detached from a common blind rivet nut gun, please refer to fig. 2, the parts within the dashed line frame are the blind rivet nut assembly 22, the blind rivet nut head 15, the compression spring 16, the locking sleeve 14, the adjusting sheath 13, and the guide head 17, the central shaft 3 is kept stationary, and the elastic stop assembly 4 in the central shaft 3 is also kept stationary. And then the rivet pulling assembly 21 is installed, so that the function of the rivet pulling gun can be realized.

In the blind rivet gun head for blind rivets provided by the embodiment, when the blind rivet is to be pulled, the motor rotates to drive the pull rod shaft 2 to rotate, and since the external thread of the pull rod shaft 2 is connected with the internal thread of the central shaft 3, the pull rod shaft 2 can only rotate but cannot move, so that the central shaft 3 is driven to move forward in a translation manner, and the steps before the step are the same as those of a blind rivet nut gun. When the central shaft 3 moves forward to drive the melon seed pieces 6 to move forward, and the melon seed pieces 6 touch the pull nail head 12, the melon seed pieces 6 can be changed from an occluded state to an open state, and at the moment, the long pull rod of the rivet can be sleeved in. The motor reversal, center pin 3 retreat, and melon seed piece 6 leaves pull nail head 12, and melon seed piece 6 gets back to initial condition, the interlock state promptly, and the long pull rod of rivet is bitten by melon seed piece 6 this moment (because melon seed piece 6 is directly being pushed up by knock pin 7 of taking spring 8), and the long pull rod of rivet is pulled up by melon seed piece 6 to realize the function of pulling the rivet.

A blind rivet rifle head that blind rivet used, through on the basis of traditional blind rivet nut rifle, pull down original blind rivet nut subassembly 22, change new blind rivet subassembly 21, make traditional blind rivet nut rifle become the blind rivet rifle, make the instrument of two kinds of differences, the user can exchange as required, reaches a tractor dual-purpose effect.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. The present invention is not limited to the above embodiments, and the specific structure thereof is allowed to be changed. All changes which come within the scope of the independent claims of the invention are to be embraced within their scope.
