Furthermore, the hook 11 is provided with a torsion spring at the hinge with the hook seat 12, so that the hook 11 can be automatically inserted into the shell when it is lowered, and it is ensured that it will not fall out of the shell when it is pulled. The front plug board 4 is arranged on the lifting seat 3, and the lifting seat 3 is slidably arranged in the first slide groove on the placement platform 6. The bottom of the lifting seat 3 is provided with a first inclined surface 15, and the first inclined surface 15 is placed on the second inclined surface 17 on the first movable seat 16. The first movable seat 16 is connected to the first movable adjustment component. Specifically, the first movable adjustment component is a first bolt 2 rotatably arranged on the base 9, and the first bolt 2 is screwed with the first movable seat 16. The bottom of the first movable seat 16 is provided with a guide component. By controlling the rotation of the first bolt 2, the first movable seat 16 can be driven to move, and then the height adjustment of the lifting seat 3 and the front plug board 4 is achieved through the cooperation of the first and second inclined surfaces. The placement seat 7 is slidably arranged in the second slide groove on the placement platform 6, and a third inclined surface 18 is arranged at the bottom of the placement seat 7, and the third inclined surface 18 is placed on the fourth inclined surface 20 on the second movable seat 19.

[0020] The working principle of the utility model is: the lock shell 13 is placed on the placement platform 6, and the front plug-in plate 4 is inserted into the buckle insertion end of the lock shell 13, the lower shell body on the rear side of the lock shell 13 is positioned, and the protruding connecting piece 14 on the lock shell 13 is placed on the placement seat 7, and then the clamping arm 8 is controlled to swing to the top of the connecting piece 14 to limit the connecting piece 14. The connecting piece 14 is connected to the lower shell body, and the positioning of the front lower shell body is realized. Then, as the tensioner drives the hook claw 11 to descend, the hook claw 11 is inserted into the lock and tightens the upper shell body of the lock shell 13. Then, the tensioner provides an upward pulling force to the lock shell 13 through the hook claw 11. At this time, the lower shell body is limited by the front plug-in plate 4 and the clamping arm 8. If the upper shell body is pulled and separated from the lower shell body, it means that the welding strength does not meet the standard. If the upper and lower shell bodies are not separated, it means that the welding strength meets the standard.

[0021] The structure of the utility model sets a corresponding tooling fixture to position the welded lock shell, and cooperates with the setting of a tensioner and a hook structure. After the hook is inserted into the lock shell, the lock upper shell is pulled by setting the pulling force of the tensioner. Only the lock upper shell that meets the welding strength requirements will not be pulled and separated from the lower shell. The detection method is more direct and reliable, and can avoid detection errors when there are cold welds or leaking welds on the inside. At the same time, the height of the tooling fixture can be adaptively adjusted according to the specifications of the lock shell, thereby improving its flexibility of use.
