Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1 to 5, the present application provides a shear block pull-off force tooling structure, which has the following specific structure and application:

the lower end of the upper ram 100 is hinged to a hinge hole 230 positioned in the middle of a horizontally disposed connecting rod 200 through a hinge shaft 110, and the left and right sides of the connecting rod 200 are provided with two horizontally oriented

slots

210 and 220 symmetrically arranged with respect to the hinge shaft 110. The lower ram 300 is hinged and positioned in the slot 210 by means of a hinge shaft 330, the hinge shaft 330 simultaneously passes through

hinge holes

331 and 330 provided at the upper portion of the lower ram 300, and accordingly, the hinge shaft 330 can appropriately slide in the slot 210. A set of

symmetrical presser feet

310 and 320 are provided on the lower portion of the lower ram 300.

Similarly, the lower ram 400 is hingedly positioned in the slot 220 by a hinge shaft 430. A set of
