# Downforce indicator device having a tool receptacle

## Abstract

A downforce indicator device for indicating a downforce acting on an insertion tool includes a tool receptacle for receiving an insertion tool, a downforce measurement unit for measuring a downforce acting on the tool receptacle, and a downforce indicator unit for indicating the measured downforce. The downforce measuring unit includes a first and a second sleeve, coaxially and displaceably disposed on the first sleeve in the axial direction. The first sleeve is connected to the second sleeve by a limiting element which can be displaced axially on the first sleeve to establish a maximum position of the second sleeve for an axial displacement of the second sleeve directed away from the first sleeve. The first sleeve and the second sleeve form a common receptacle for receiving a spring element acting on the second sleeve in the direction towards the maximum position. The maximum position is associated with a minimum downforce.
