Extractor for extracting conical spacers in concrete walls or pillars and associated method

An extractor for extracting a spacer from a concrete wall, the extractor comprising:

• a stem having at a proximal end a handle and at a distal end a spacer engagement device, the spacer engagement device being configured to connect with the spacer;
• a mobile element positioned about and slidable on the stem between the handle and the spacer engagement device, the mobile element moveable between a retracted position to which the mobile element is moved in order to apply a proximally applied force to the spacer engagement device to contribute to the extraction of the spacer from the concrete wall, and an advanced position to which the mobile element is moved in order to apply a distally applied force to push and release the spacer from the conical spacer engagement device;
• the stem including a proximal stop having a proximal stop surface and a distal stop having a distal stop surface, the mobile element being slidable between the proximal and distal stop surfaces of the stem, the mobile element having a proximal stop surface that is configured to engage with the proximal stop surface of the stem when the mobile element is in the retracted position;
• the mobile element including a distal stop surface that is configured to engage with the distal stop surface of the stem when the mobile element is in the advanced position;
• the proximal stop surface of the mobile element residing inside a proximal recess of the mobile element.
