This operation is more complicated and troublesome
Since the operator has to open the spring safety catch by hand, only one hand is used to stabilize the work tool, so that the entire weight of the work tool must be borne by one hand

Embodiment Construction

[0028] figure 1 The shoulder-back device shown comprises a belt device 10 , a fastening device 50 and a free cutter 1 . Instead of the free cutter 1 , the belt device 10 can also be used for another hand-held power tool, for example a tree splitter, a harvesting tool such as, for example, an olive shaker or the like. The free cutter 1 includes a guide tube 2, a motor housing 3 is provided at one end of the guide tube and a silk harvesting head 4 is provided at the opposite end. A harvesting wire 6 protrudes from the silk harvesting head 4 , which forms the tool of the free cutter 1 . The movement path of the cutting wire is covered by a guard plate 5 on the side directed towards the operator 16 . A drive motor, not shown, which can be, for example, a two-stroke engine or a mixed-lubrication four-stroke engine is located in the engine housing 3 . However, the drive motor can also be an electric motor. The drive motor drives a drive shaft which is rotatably arranged in the g...

Abstract

The present invention relates to a hook and support assembly. The hook for fastening a hand-held working apparatus to a belt arrangement (10) has an open frame (46) with an access opening (23) and a closure member (22). The closure member (22) at least partly closes the access opening (23) in a rest position (32) of the closure member (22). The closure member (22) can be swiveled from the rest position (32) to a first open position (33) and to a second open position (34), so that a hand-held working apparatus which is arranged on the belt arrangement (10) can in a simple manner be both fastened to the belt arrangement and detached therefrom. A carrier arrangement with a hand-held working apparatus, a belt arrangement (10) and a fastening device (50) for fastening the working apparatus to the belt arrangement (10) comprises a hook (9) and an element to be engaged in the hook (9).

Description

Background technique [0001] The invention relates to a hook of the kind stated in the preamble of claim 1 and to a shoulder carrier device stated in the preamble of claim 15 . Background technique [0002] Known from DE 3536676 A1 is a free-cutting tool on which the shoulder strap can be fixed by means of a spring safety hook. Spring safety hooks of this type generally have a resilient locking member which can be swung inward against the force of a spring into the receiving opening of the hook. The locking member is generally locked in a form-fitting, fixed connection towards the outside of the hook. [0003] In order to release the power tool from a backpack of this type, the locking part of the spring safety hook must be pivoted by hand and the hook must be disengaged from the opening. This operation is more complicated and troublesome. Since the operator has to release the snap catch with his hand, only one hand is used to stabilize the power tool, so that the entire w...
