The working principle is as follows:

when the battery modules need to be stacked, a worker can enter the control box 2 to control the T-shaped connecting plate 4 to drive the stacking clamping mechanism 5 to move on the upright post 3, so that the height of the stacking clamping mechanism 5 can be adjusted to clamp and stack the battery modules, when the battery modules are clamped, the two arc-shaped lifting rods 52 are controlled to extrude the two moving rods 53 by the arc-shaped lifting rods 52, the two moving rods 53 are extruded to rotate, when the moving rods 53 rotate, the sliding blocks are driven to move, the elastic memory metal plate 7 is extruded by the mutual approaching movement of the two sliding blocks, the elastic memory metal plate 7 is extruded to be in an arc shape to be elastically deformed, and meanwhile, the two round rods 81 move to two sides along an arc area path formed by the deformation of the elastic memory metal plate 7 under the action of the elastic potential energy of the elastic rods 82, the scraper 84 moves along the outer surface of the bottom wall of the movable case 54 by the movement of the round bar 81, so that the bottom wall of the movable case 54 is cleaned, and the influence on the clamping of the battery module caused by the impurity left on the battery module is prevented when the battery module is clamped.

Meanwhile, when the elastic memory metal plate 7 is elastically deformed, the piston rod is driven to move, the gas in the gas cavity 551 is extruded by the movement of the piston rod, the space of the gas moving in the gas cavity 551 is gradually reduced under the action of the extrusion force, the gas pushes the arc-shaped rotating plate 101 through the placing groove 552 under the action of the pressure after the space is reduced, the gas passing through the placing groove 552 is divided towards two sides due to the special shape of the arc-shaped rotating plate 101, so that impurities on the resistance increasing plate 102 are cleaned by the pushing force of the gas flow, the cleaning effect of the clamping device in the device is enhanced, secondly, when the gas in the gas cavity 551 passes through the placing groove 552, the friction block 91 leaves the inside of the placing groove 552 under the pushing action of the gas flow, and meanwhile, the friction block 91 is supported by the arc-shaped support rod 93, so that the friction block 91 is always attached to the outer surface of the battery module when the device clamps the battery module, thereby the contact of clutch blocks 91 and battery module surface has increased battery module and fixture's area of contact, frictional resistance has been increased, thereby can be at utmost prevent that battery module from taking place the displacement because self action of gravity on fixture, when arc rotating plate 101 takes place to rotate, can extrude arc elastic plate 103, arc elastic plate 103 after the extrusion takes place to warp, thereby have the effect of an outside thrust force to arc bracing piece 93, can strengthen the supporting role of arc bracing piece 93 to clutch blocks 91 under the effect of thrust force.
