Abstract

A retaining device for a steam swab includes a first primary clamp, a second primary clamp and an auxiliary clamp. Each of the first primary clamp, the second primary clamp and the auxiliary clamp are respectively pivotal relative to the upper casing and are provided with bosses so that a fabric of the steam swab is able to be securely clamped by the first primary clamp, the second primary clamp and the auxiliary clamp.

Claims

1. A retaining device for a steam swab having a pole assembly and a base assembly, the retaining device comprising:

a first primary clamp having two mutually aligned pivot holes defined in opposite inner faces of the first primary clamp to correspond to two distal ends of a first T shaped pivot and a guide formed on a bottom face of the first primary clamp to correspond to a first distal end of a first spring;

a triangular upper casing having a first, a second and a third indentation respectively defined in three distal corners of the triangular upper casing, wherein the first indentation has a first pivot seat formed to correspond to a distal end of the first T shaped pivot and a spring seat formed to correspond to a second distal end of the first spring;

a second primary clamp having two mutually aligned pivot holes defined in opposite inner faces of the second primary clamp to correspond to two distal ends of a second T shaped pivot and a guide formed on a bottom face of the second primary clamp to correspond to a first distal end of a second spring, wherein the second indentation has a second pivot seat formed to correspond to a distal end of the second T shaped pivot and a spring seat formed to correspond to a second distal end of the second spring; and

an auxiliary clamp having two mutually aligned pivot holes defined in opposite inner faces of the auxiliary clamp to correspond to two distal ends of a third T shaped pivot and a guide formed on a bottom face of the auxiliary clamp to correspond to a first distal end of a third spring, wherein the third indentation has a third pivot seat formed to correspond to a distal end of the third T shaped pivot and a spring seat formed to correspond to a second distal end of the third spring,

whereby the first primary clamp, the second primary clamp and the auxiliary clamp are able to pivot relative to the upper casing and are adapted to securely clamp a fabric of the steam swab.

2. The retaining device as claimed in claim 1, wherein the upper casing is triangular so that the steam swab is able to extend into compact space.

3. The retaining device as claimed in claim 1, wherein the first primary clamp, the second primary clamp and the auxiliary clamp are respectively provided with first bosses correspond to second bosses formed on the first, the second and the third indentation so that the fabric is sandwiched between the first and the second bosses.

4. The retaining device as claimed in claim 2, wherein the first primary clamp, the second primary clamp and the auxiliary clamp are respectively provided with first bosses correspond to second bosses formed on the first, the second and the third indentation so that the fabric is sandwiched between the first and the second bosses.
