Preferably, the upper pulling seat and the cross rod are correspondingly provided with two upper insertion holes, the lower pulling seat and the cross rod are correspondingly provided with two lower insertion holes, two ends of the cross rod on the upper pulling seat respectively penetrate through the two upper insertion holes and are connected and locked through the locking nut, and two ends of the cross rod on the lower pulling seat respectively penetrate through the two lower insertion holes and are connected and locked through the locking nut. The two ends of the cross rod are locked and limited through the locking nuts, the connection is reliable, and the cross rod is prevented from moving transversely.

Preferably, the end face of the adhesion raised head is of a convex spherical structure, and the adhesion groove is of a concave spherical structure. The contact area of the adhesion raised head and the adhesion groove is large, and the reliable adhesion of the sealant is facilitated.

Preferably, go up the pulling seat and all include connecting portion, pulling portion with the pulling seat down, and connecting portion are the U-shaped structure, and the horizontal pole is connected and is close to the open position on connecting portion, and pulling portion sets up and is close to the intermediate position and extend to keeping away from the horizontal pole direction in the connecting portion bottom. The upper pulling seat and the lower pulling seat are connected with the cross rod conveniently and reliably, and the upper pulling seat and the lower pulling seat are stressed stably and are convenient to pull the upper pulling strip and the lower pulling strip.

Preferably, the upper brace and the lower brace are respectively provided with a reinforcing column, the cross section of each reinforcing column is square, and the adhesion raised heads and the adhesion grooves are respectively arranged at the end parts of the two reinforcing columns. The upper brace and the lower brace have good structural strength.

Compared with the prior art, the beneficial effects of the utility model are that: when the storage battery sealant is used for strength testing, the testing device cannot be broken, and the upper pulling strip and the lower pulling strip cannot be displaced transversely, so that the testing accuracy is guaranteed.
