[0045] Start the lifting motor 8, and the two screw rods 6 are driven to rotate synchronously under the meshing action of the two first sprockets and the first chain 7, thereby driving the two lifting blocks 5 and the installation box 9 to move downward synchronously through the action of the thread. When the installation box 9 moves downward to a suitable position, the stirring shaft 11 contacts the filling body. At this time, the driving gear 16 is meshed with the fixed rack 17, so that when the installation box 9 continues to move downward, the driving shaft 13 is driven to rotate through its meshing action, and the driving bevel gear 14 and the driven bevel gear 15 drive the stirring shaft 11 and multiple stirring rods 12 to rotate, so as to stir the filling body and improve the mixing degree of the filling body.

[0046] When the installation box 9 moves downward to a fixed position, the two extrusion columns 39 contact the two sliding racks 34, thereby forcing the sliding racks 34 to move downward and engage with the extrusion gear 33, thereby driving the rotating shaft 31 and the cam 32 to rotate. Through the extrusion effect of the cam 32 and the elastic effect of multiple buffer springs 23, the bottom plate 21 and the curing tube 24 are reciprocated and lifted and vibrated, thereby eliminating bubbles in the filling body, improving the pressure resistance effect, and improving the test performance.
