Abstract

The invention discloses a screwing device which comprises a screwing device body and a right-angle speed reducer. The screwing device body is provided with a screwing sleeve used for locking and unlocking a fastener and a rod part capable of driving the screwing sleeve to rotate, and in addition, a power output part of the right-angle speed reducer directly transmits power to the rod part of the screwing device body. According to the screwing device, power transmission to the screwing device body can be conveniently achieved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a screwing device. Background technique [0002] In new energy vehicles, in order to balance the installation firmness of the battery pack and the quickness of battery pack replacement, the vehicle is usually equipped with a special fastening device. In battery swap mode, in order to fasten and prevent the battery from loosening, it is preferable to use fasteners with anti-loosening function to fix the battery to the vehicle body (for the anti-loosening structure, please refer to CN106740029 A). Critical areas of the screwing tool and fastener need to contact and create stress before the tightening / loosening action can proceed smoothly. When loosening the fastener with anti-loosening function, the screwing tool needs to jack up the anti-loosening part first. If the anti-loosening part is not pushed away, the loosening action will start, which will cause damage to the anti-loosening p...
