In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a split type pull head, is including drawing nose and end, the spliced eye has been seted up to the end, has preset the spring leaf in the spliced eye, draws the one end of nose to pass through the spliced eye and peg graft with the end, draws the lateral wall of nose to be constructed with outside extension butt portion, and the below of drawing nose butt portion still inwards extends to be constructed with the joint groove, terminal and the joint groove butt in spring leaf top, draw the nose to pass through spring leaf and butt portion realization and end riveting.

Further elaborating, the spring leaf is by the sheetmetal bending type, and the bottom of sheetmetal is equipped with elasticity step, and the top upper surface of spring leaf and the pore wall butt of spliced eye.

Further, the extending edge of the insertion hole of the bottom head is provided with a step type downward extending abutting plane, and the abutting part abuts against the abutting sheet surface.

Stated further, the other end of the pull nose is in clearance fit with the bottom head.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model cancels the former connection mode of punching and tensioning fixation, but adopts the mode of splicing and riveting, one end of the bottom head extends downwards and is provided with a splicing hole, the pull nose is spliced with the pull head through the splicing hole, and riveting is realized through the structure of the pull nose and the spring piece, thereby effectively preventing the pull nose from falling off and improving the reliability of the connection of the pull nose (cap) and the bottom head; the pull head is inserted without using a stamping machine, so that the manufacturing cost of the pull head is reduced.
