Abstract

The invention relates to the field of automobiles, in particular to a screwdriver for production of new energy vehicles, which includes a screwing sleeve, which is coaxially inserted on a transmission rod, and the transmission mechanism is matched by the rotation of the working end of the rotary drive device. The transmission rod transmits the torque to the screwing sleeve, and the screwing sleeve passes through the cylinder part, the first seat part and the first rod part from top to bottom, and the inner wall of the cylinder part is provided with a vertically surrounding card slot, The peripheral side of the first seat part is provided with several first articulated seats, the first articulated arm is articulated on the first articulated seat, the bottom of the first articulated arm is articulated with the second articulated arm, and the other end of the second articulated arm is articulated Installed on the second articulated seat provided around the second seat of the transmission rod, this technical solution realizes alignment through the hinged structure of the first articulated arm and the second articulated arm when the distance between the screwing sleeve and the transmission rod is shortened. Self-adaptive clamping is performed on the circumference of the fastener, thereby improving the combination degree of the screwdriver and the fastener.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a screwdriver for production of new energy automobiles. 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 the battery replacement mode, in order to realize the fastening and anti-loosening of the battery and the vehicle body, it is preferable to use a fastener with an anti-loosening function to realize the fixed and anti-loosening structure of the battery and the vehicle body. Please refer to CN106740029A. 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...
