The invention relates to an improved type element feed mechanism relating to the technical field of electronic element insertion machines. The improved type element feed mechanism comprises a guide rail fixing seat, a long guide rail and a driving mechanism, wherein the long guide rail is arranged on the guide rail fixing seat; the bottom end part of the long guide rail is provided with an arc-shaped guide rail; the upper end part of the arc-shaped guide rail is butted with the lower end part of the long guide rail; a guide rail pressing strip is arranged above a guide slot of the arc-shaped guide rail; the lower part of the arc-shaped guide rail is provided with a movable feed slide block; the feed slide block is provided with a slot capable of containing only one electronic element; andthe driving mechanism is used for driving the feed slide block to move back and forth. In the invention, the driving mechanism conveys only one electronic element to a specified position by operatingone time so as to greatly enhance the clamping accuracy of a clamping device, reduce the difficulty in clamping work and enhance the feed efficiency of the insertion machines, therefore the production efficiency of a PCB (Printed Circuit Board) is enhanced; and in addition, the advantages of obvious progressiveness and high practicability are achieved.
