A forward pull type bolt lock structure of a slide, comprising:

• an outer rail, having lips and provided with a first locking block and a second locking block;
• an inner rail, received in the lips of the outer rail, the inner rail having lips protruded toward the outer rail, the inner rail provided with a mounting hole for a pivot member to pivot one end of a positioning member, the other end of the positioning member provided with a guide block, one side of the positioning member having a press bar which is rested on one lip of the inner rail, the other side of the positioning member having a wall which is provided with a cutout and a stop portion;
• a slide plate received between the lips of the inner rail and the outer rail, the slide plate provided with a drawing block for drawing the slide plate to move in the inner rail, the slide plate combined with one end of a restoring member, the other end of the restoring member is combined with the inner rail, the slide plate provided with a guide slot, the guide slot having an oblique guide face, the guide block of the positioning member is supported on the oblique guide face;
• when the inner rail is extended relative to the outer rail, the stop portion of the positioning member of the inner rail is supported on the first locking block of the outer rail, and the cutout of the wall of the positioning member is locked on the second locking block of the outer rail;
• when the inner rail is retracted into the outer rail, the positioning member may press the press bar to pivot, so that the stop portion of the positioning member of the inner rail is separated from the first locking block of the outer rail, and the cutout of the wall of the positioning member is separated from the second locking block of the outer rail;
• and
• the slide plate may be moved with the inner rail, and the oblique guide face of the guide slot presses the positioning member to pivot, so that the stop portion of the positioning member of the inner rail is separated from the first locking block of the outer rail, and the cutout of the wall of the positioning member is separated from the second locking block of the outer rail.
