Reciprocating tool

A reciprocating tool, comprising:

• a casing neck;
• a reciprocation conversion mechanism disposed in the casing neck;
• a saw blade that is connected to the reciprocation conversion mechanism and reciprocates;
• a shoe;
• and
• a shoe adjustment mechanism;
• wherein the shoe adjustment mechanism comprises a cover plate and a slide pin, wherein the cover plate is connected to the reciprocation conversion mechanism;
• wherein the shoe comprises a support and a guide plate pivotably connected to the support;
• wherein the guide plate is disposed between the cover plate and the reciprocation conversion mechanism, wherein the guide plate has a slide groove substantially parallel to a direction of reciprocation, and wherein the slide pin passes through the slide groove of the guide plate;
• wherein the shoe adjustment mechanism has a locked position and an unlocked position, wherein in the locked position the slide pin is engaged in the slide groove of the guide plate and the guide plate is locked by the slide pin, and wherein in the unlocked position the slide pin is at least partially disengaged from the slide groove and the guide plate is slidable in the direction of reciprocation;
• wherein the slide pin is substantially in a shape of a hollow cylinder that comprises a first portion having a first diameter and a second portion having a second diameter and wherein the first portion and the second portion substantially form a stepped shape with the first diameter being smaller than the second diameter;
• wherein the shoe adjustment mechanism further comprises an insertion pin that is barbed at a first end, wherein a barbed part of the insertion pin extends into the slide pin and the barbed part engages with an upper edge of the first portion of the slide pin, and wherein an elastic component is disposed between the insertion pin and the reciprocation conversion mechanism.
