Abstract

The invention discloses a battery pack rotating mechanism in a handheld electric tool. The battery pack rotating mechanism comprises a rotating seat capable of rotating relative to an electric tool body. Two power terminals are arranged at the lower end of the rotating seat. A battery pack is fixed to the rotating seat, and the two electrodes of the battery pack are just in contact with the two power terminals on the rotating seat at the moment. A movable support is fixed to the upper portion of the rotating seat. Two movable contact pieces are inserted in the movable support. The lower ends of the two movable contact pieces are connected with the two power terminals on the rotating seat through wires correspondingly. A fixed support is fixed in the electric tool body above the movable support. A fixed contact piece is correspondingly arranged at the position, above each movable contact piece, on the fixed support. The upper ends of the two fixed contact pieces are connected with a positive line and a negative line of a switch in the electric tool body correspondingly, and the lower ends of the two fixed contact pieces are in contact with the upper ends of the lower corresponding movable contact pieces correspondingly. A positioning mechanism is arranged between the rotating seat and the electric tool body. The battery pack rotating mechanism has the beneficial effect that the positive line and the negative line of the switch cannot be affected during rotation of the battery pack.

Description

technical field [0001] The invention relates to a hand-held electric tool, in particular to a battery pack rotating mechanism in the hand-held electric tool. Background technique [0002] At present, rechargeable hand-held electric tools with battery packs are deeply loved by users because of their ease of use and other features. However, the battery pack in the rechargeable hand-held electric tool is fixed to the body of the electric tool, so in some relatively narrow working spaces, the use of the rechargeable hand-held electric tool is greatly limited. Therefore, there is an urgent need to invent a battery pack rotation mechanism that can rotate freely and will not affect the positive and negative lines of the switch inside the electric tool body during the rotation process. Contents of the invention [0003] The purpose of the present invention is to provide a battery pack rotating mechanism in a hand-held electric tool that can rotate freely and will not affect the p...
