Abstract: A component for a bit driving tool is taught having a mid-chamber telescopically received in an outer chamber, a bit storage chamber formed in the mid-chamber and surrounding and rotatable about a central bore, a central rod axially movable through the central bore when the mid-chamber is telescopically retracted into the outer chamber and a flexible arm comprising a magnetic end, movable into and out of axial alignment with the central bore. Telescopic extension of the mid-chamber out of the outer chamber positions the magnetic end of the flexible arm to magnetically connect with a rear end of a bit stored in the bit storage chamber and telescopic retraction of the component moves the flexible arm and the magnetically connected bit radially into the central bore and wherein further telescope retraction of the component pushes the bit axially through and out of the component. A locking tip for use with a bit driving unit is also taught.

Abstract: A fluororubber wax-melting tray and a cleaning method thereof are disclosed. The fluororubber material of the disclosure is a synthetic polymer elastomer with high temperature resistance, corrosion resistance and low wear resistance. The fluororubber wax-melting tray has the same wax melting effect as the existing ceramic or metal wax melting trays. The shape of the wax melting tray is changed by the external force exerted by pushing the bottom of the fluororubber wax melting tray lightly. When both the external force tending to change the shape of the wax-melting tray and the adsorption force between the wax molecules are greater than the adsorption forces between the fragrance wax and the wax melting tray, the absorption force between a wax piece and the wax melting tray is released, and the whole solidified wax piece can be completely peeled off.

Abstract: A component of a bit driving tool is presented, having a mid-chamber, telescopically received in an outer chamber. A bit storage chamber is formed in the mid-chamber, surrounding and rotatable about a central. A central rod extends through and out of the outer chamber. A dual lever arm comprising a first magnetic end and a second end is pivotably connected to the central rod such that the dual lever arm pivots into and out of axial alignment with the central bore. Telescopic extension of the mid-chamber out of the outer chamber positions the dual lever arm to magnetically connect with a rear end of a bit stored in the bit storage chamber and telescopic retraction of the component pivots the bit radially inwardly into the central chamber and wherein further telescope retraction of the component pushes the bit through the central chamber until the bit extends out of the component.
