As shown in fig. 6B, a force application portion 413 may be disposed on a surface of the first acting element 41 facing the battery 30, and the force application portion 413 is configured to contact the battery 30 and apply force to the battery 30.

The following describes a process of fixing the battery 30 using the battery fixing device 100: firstly, an operator places the battery 30 on the receiving part 13 of the carrier 10, and then fixedly installs the fixing assembly 20 on the carrier 10; the operator then adjusts the fixing assembly 20 through the adjusting member 22 provided on the fixing assembly 20, thereby stably fixing the battery 30 to the carrier 10.

When the operator rotates the adjusting portion 221 of the adjusting member 22 clockwise as viewed from top to bottom, the adjusting portion 221 drives the driving portion 222 to rotate clockwise, and then the driving portion 222 drives the first rotating member 44 of the first fixing member 40 to rotate counterclockwise and drives the second rotating member 54 of the second fixing member 50 to rotate clockwise as viewed from front to back; during the rotation of the first rotating member 44, since the first housing 43 restricts the circumferential movement of the first acting member 41 and the second acting member 42, the first rail portion 442 rotates counterclockwise with respect to the first acting member 41 and the second acting member 42; since the radial distance from the inner diameter and the outer diameter of the first protrusion 442a to the center 30a of the battery 30 is gradually reduced in the clockwise direction, the radial distance from the inner diameter and the outer diameter of the second protrusion 442b to the center 30a of the battery 30 is also gradually reduced, and the radial slot size of the first groove 442c between the first protrusion 442a and the second protrusion 442b is also gradually reduced in the clockwise direction, the first protrusion 442b and the second protrusion 442b exert a force on the force-receiving protrusion 411a of the first acting member 41 in the radial direction toward the battery 30 during the counterclockwise rotation of the first rotating member 44, and since the first acting member 41 is mounted on the first housing 43 in a manner movable in the radial direction with respect to the first housing 43, the first acting member 41 moves radially toward the battery 30, so that the force-applying portion 413 of the first acting member 41 applies a pressing force in the radial direction to the battery 30 to fix the battery 30 to the carrier 10.

In this process, the movement and action of the second acting element 42 are the same as those of the first acting element 42, and will not be described again.

When the regulating member 22 is rotated in the clockwise direction as viewed from the top to the bottom, and at this time, the second rotating member 54 is rotated counterclockwise as viewed from the rear to the front, and in the clockwise direction, since the radial distances from the inner diameter and the outer diameter of the third projection 542a to the center 30a of the battery 30 are gradually reduced, the radial distances from the inner diameter and the outer diameter of the fourth projection 542b to the center 30a of the battery 30 are gradually reduced, and the radial slot dimension of the second groove 542c between the third projection 542a and the fourth projection 542b is also gradually reduced in the clockwise direction, the second rotating member 54 applies a force toward the center 30a of the battery 30 to the third acting member 51 and the fourth acting member 52 during the counterclockwise rotation, so that the third acting member 51 and the fourth acting member 52 move in the radial direction and apply a pressing force to the battery 30 to fix the battery 30 to the carrier 10. The above rotation processes of the first rotation member 44 and the second rotation member 54 are completed in the housing.

Further, at least a portion of the column protruding from the opening of the first housing 43 abuts against the first spacer 443 of the first rotating member 44, so that when the first rotating member 44 rotates in a clockwise direction as viewed from front to rear, the fifth acting member 46 can be moved in a radial direction away from the battery 30 due to friction force with the first spacer 443 to release the fixation of the battery 30.
