The assembly design of the traditional rivet gun head is generally as shown in the previous paragraph of the "Molding Tip Structure Improvement" of M418762. The head body of the rivet gun and the internal transmission rotating rod are pulled and controlled by the threaded lock. The moving member, wherein the moving guiding end is set to have a polygonal cross section, and the two rotating movements of the moving member and the rotating rotating rod structure simultaneously rotate and linearly slide, generally polygonally assembled and assembled, and the rotating rod is relatively screwed When moving parts are formed, the tensioning of the tensioned pull-ups is easy to cause wear, especially the head body is usually made of plastic steel or aluminum, zinc die-casting, and the texture is soft, and the metal moving parts are twisted and stressed and sliding. Under the multi-directional force, the corners of the polygons in the body are easy to form a serious wear state, which is easy to be stuck and unable to be controlled during sliding and transfer control. For this reason, the creator improved it as announced in M541913. "Electric rivet gun improved structure", a metal sliding sleeve seat is arranged inside the head base body, and the seat body is internally divided into equal lengths of the sliding groove for the predetermined relative ribs on the sliding member, as The plug-in sliding guide greatly improves the wear and tear of the traditional polygonal type. However, the insert of the sliding member is assembled by the end of the head seat to the rivet operation end, and the whole pull control design is The clamping block at the outermost end is used as a force for the transfer and holding of the clamping shank, so the most common wear loss situation is the grinding loss of the clamping block, when the edge of the clamping edge is enlarged. It is necessary to replace the clamping block with new ones before continuing to use the rivet. However, the previously inserted sliding groove is only set according to the sliding length, and all the components need to be unloaded by the insertion side during the replacement. In order to make the replacement of the clamping block, it is extremely inconvenient to operate. How to effectively improve the assembly and disassembly structure, and to meet the need of rapid assembly and replacement, so that the rivet machine can be used to meet the practical needs. The reason for this creative research and development.

In view of the built-in structure of the conventional rivet gun head seat, the inventors have developed a practical defect of inconvenient assembly and disassembly in use, and have redesigned the design to improve the structure of the electric rivet gun head of the present invention. The detachable sliding chute of the sliding body seat of the seat body is extended to one end of the plug body of the head seat body, and the locking assembly of the cone head member is matched, so that the sliding member is directly inserted from the side of the tapered head end. It is assembled into the sliding sleeve to facilitate the disassembly and assembly of the sliding structure, which effectively improves the inconvenience of the pull-controlled drive repair and replacement assembly.

The main purpose of the invention is to extend through the sliding groove of the sliding sleeve seat of the head base body to the outer end of the conical head of the head seat body, and the sliding member built in the sliding sleeve seat is directly after the cone head member is removed. It is assembled by one end of the conical head, and cooperates with the locking position of the conical head piece to provide easy assembly and assembly of the rivet operation assembly and wear to achieve the head joint The purpose of disassembly and assembly is convenient and practical.
