Problems solved by technology

[0004] But sometimes this display leads to problems, since it cannot be ruled out that the supplied tightening torque is indicated in one dimension and the tool is operated in another, so that too high or too low a torque will be transmitted to the threaded connection
[0005] Another problem with this tool is that the tightening torque can be adjusted and this adjustment of the tightening torque does not always work correctly, so that this tool must be calibrated from time to time
Errors can also occur here due to confusion of measuring units

Embodiment Construction

[0023] figure 1 A tightening tool 1 is shown in the form of a torque tightening tool comprising a handle 2 substantially comprising a circular cross-section. The handle 2 is preferably made of one or more synthetic materials.

[0024] The tightening tool 1 comprises at the end 4 a working part 5 of common design, which is connected to the handle 2 . The working part 5 consists of a substantially circular housing 6 into which is inserted a rotatable element 7 whose steering operability with respect to the housing 6 can be selectively determined in two directions of rotation, and Said element 7 comprises a driver 8 with a square cross-section, which can be connected to a tool nut not further described comprising jaws of different sizes and intended to be connected to a tool nut not further described of the threaded connection. Furthermore, for securing tools with jaws of different shapes and / or dimensions, rectangular receivers or working parts in the form of pins of other re...

Abstract

The invention relates to a tool, in particular a screwing tool (1), comprising a handle (2), a working part (5) that is connected to the handle and that is used to open or close a threaded connection, and an display device (10) that displays a working value, for example a tightening torque of the threaded connection, wherein the display device (10) has at least two representations of the working value, in particular the tightening torque. In order to develop a generic tool in such a way that incorrect operation can be prevented with sufficient reliability, a covering device (17) is provided, which covers at least one working value and / or is designed in such a way that only one working value can be displayed in the display device (10).

Description

technical field [0001] The present invention relates to a tool, in particular to a tightening tool comprising a handle; a working part connected to the handle and used to open or close a threaded connection; and a display device which displays the working value , such as the tightening torque of the threaded connection, wherein the display device includes at least two representations of the working value, specifically the tightening torque. Background technique [0002] Such tools are known in the prior art, and they are in particular so-called torque tightening tools, which comprise a handle and a working part, usually consisting of a square placed in a head in a rotatable manner , the block can be blocked according to the working stroke, that is, the opening and closing of the threaded connection. Furthermore, such tools comprise means for limiting the tightening torque of the tool depending on the permissible tightening torque of the threaded connection. Typically, the ...
