[0030] Furthermore: the staff only needs to shake the rocker 1203 on the left and right sides to drive the clamping blocks 1402 on the front and rear sides to move inward synchronously to complete the clamping and limiting of the workpiece body 4. The operation is simple and convenient for the staff to use, so that the position of the workpiece body 4 will not be shifted during spot welding, which increases the stability of the workpiece body 4 during processing. At the same time, the easy-to-adjust clamping blocks 1402 also enable the limiting device to limit workpiece bodies 4 of different sizes when in use, thereby increasing the stability of the device when in use.

[0031] Embodiment 2

[0032] See also Figure 1 , Figure 2 and Figure 4 On the basis of the first embodiment, it is further obtained that the pressing mechanism 2 includes a pressing component 21 and a resetting component 22 , the pressing component 21 is arranged in the supporting component 11 , and the resetting component 22 is arranged on the top of the pressing component 21 .

[0036] After that, the staff shakes the rocker 1203 on the left and right sides, and the shaking of the rocker 1203 on the left and right sides drives the double-axis threaded rod 1201 to rotate through the rocker arm 1202. The rotation of the double-axis threaded rod 1201 drives the threaded cylinder 1301 on the front and rear sides to move inward synchronously. The inward movement of the threaded cylinder 1301 drives the clamping block 1402 to move inward through the fixed arm 1 1401 and the fixed arm 2 1403. The clamping blocks 1402 on the front and rear sides move inward and contact with the front and rear sides of the workpiece body 4. At this time, the clamping and limiting processing of the workpiece body 4 is completed.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
