Abstract

Tap block key (1) with two inner four edges (4) and (6) and a movable (5) and fixed jaw (8).

Description

To the Tighten and release from screw connections to radiators Water pump pliers, pipe wrenches and open-end wrenches are used.

• 1. Die Werkzeuge können nicht eingesetzt werden, da die Baumaße zu groß sind.
• 2. Zangen beschädigen mit den scharfkantigen Zähnen die Verschraubungen
• 3. Hautabschürfungen und Quetschungen der Hände des Werkzeugbenutzers, da er mit nicht geeignetem Werkzeug abrutscht.

The following problems occur.

• 1. The tools can not be used because the dimensions are too large.
• 2. Pliers damage the screw connections with the sharp-edged teeth
• 3. Skin abrasions and bruises of the hands of the tool user as he slips off with unsuitable tools.

These Problems are with the features listed in protection claim 1 solved.

With the invention is achieved, screwing on inaccessible To solve and wear, not to damage the fittings that needed To achieve torque and reduce the risk of injury.

A advantageous embodiment of the invention is in protection claim. 6 shown. The use of the inner square with ratchet and extension allows that generating a high torque even in tight spaces.

An embodiment of the invention will be described with reference to 1 to 3 explained.

It demonstrate:

1 the tap block key ( 1 )

2 the use of the tap block key with ratchet ( 3 ) and extension ( 2 ) in confined spaces.

3 the tap block key with extension ( 2 ) to increase the torque.

In 1 the ratchet function of the tap block key ( 1 ) clear. By pressing the nose ( 7 ) against the spring ( 9 ) the distance measure ( 10 ). By increasing the distance ( 10 ), the tap key can be actuated in increments of 60 ° over the corner of the fitting.

Furthermore, by geometric adaptation of the jaws ( 5 ) and ( 8th ) to the extent of the screw connection no damage to the surface of the screw connection achieved.

In 2 It is shown that by attaching the inner quadrilateral ( 4 ) and the use of ratchet ( 3 ) and extension ( 2 ), even in extremely confined spaces, a loosening or tightening the screw is possible.

In the 3 It is shown that by attaching the inner quadrilateral ( 6 ) And the use of the extension ( 2 ), even in tight spaces, a high torque for loosening or tightening the screw is possible.
