Embodiment Construction

[0082] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0083] Such as figure 2 Shown: the fixed flange of the multipurpose tool (10) runs around its axis (14) with a small turning angle of 1.0-2° and a high frequency of 5000-25000 times per minute.

[0084] figure 2 The fixed flange of the multipurpose tool (10) is connected with the movable outer flange (13a) of the fixed working head (20), wherein the movable outer flange (13a) is fixed with screws (fixing parts 18), and the screws (13a ) pass through the fixing hole (22) on the fixing unit (21) of the working head (20) and be fixed on the fixing flange, and the fixing flange of the multi-purpose tool (10) is provided with a hollow area ( 25) the small limit post (15) that plays shape lock limit effect. Certainly the hollowed-out area (25) of working head (20) also can be made not with the limit post ...

Abstract

The invention relates to a rapid-mounting working head of a multipurpose tool. The rapid-mounting working head of the multipurpose tool is good in rigidity. A fixing unit for to be fixed by the multipurpose tool and a function end which is integrated with the fixing unit or is connected with the fixing unit to form a whole are arranged on the rapid-mounting working head. A fixing hole is formed in the fixing unit of the rapid-mounting working head. A plug hole is formed in the fixing unit of the working head. The inscribed circle diameter of the plug hole is larger than that of the fixing hole. An outer flange of the first multipurpose tool can be axially inserted into and pulled out of the plug hole. The plug hole is communicated with the fixing hole. A fixing piece of the outer flange of the multipurpose tool can pass through a channel from the plug hole to the fixing hole in the radial direction. Besides, the fixing hole of the rapid-mounting working head is closed, and the rapid-mounting working head can be rapidly mounted on the first multipurpose tool.

Description

technical field [0001] The invention relates to a quick-install working head of a multi-purpose tool, in particular to a quick-install working head of a multi-purpose tool with good versatility and practicability. The multi-purpose tool is invented by the FEIN company (FEIN) of Germany, and the FEIN company calls it an oscillating drive tool in its patent literature. [0002] The fast-loading working head of the multi-purpose tool in the present invention refers to the working head that can be quickly replaced on the multi-purpose tool, not only including the working head for the quick-installing multi-purpose tool of the free-spinning tool, but also including the need to operate the screwdriver, which will be fixed The movable flange of the working head is not completely separated from the ordinary multi-purpose tool, so that the working head can be replaced. [0003] The "closed mouth" of the fixing hole of the fast-loading working head among the present invention is corres...
