Description

Technical Field

[0001] The present invention relates to the technical field of punching, and in particular to a punching positioner. Background Art

[0002] When installing the slide rails and panel connectors on the drawer, it is necessary to punch holes (fixing holes) in the drawer, and then fix the slide rails and panel connectors on the drawer through the fixing holes. When punching, a punching locator is needed to guide the punching drill bit to punch holes. For example, the cabinet door hinge installation punching locator announced by Chinese patent document No. CN207669444U on July 31, 2018 can guide the punching drill bit to punch straight holes. Drawers generally use a punching locator similar to CN207669444U to guide punching, but this punching locator can only punch straight holes. When installing panel connectors of some types of drawers, in order to ensure that the panel connectors are firmly installed, the panel connectors are fixed to the drawers by inclined screws. Therefore, the drawers need to have oblique fixing holes. Punching locators like CN207669444U are not suitable for drilling such oblique fixing holes. Another special punching locator is required to guide the drilling of oblique holes. The structure of such punching locators is relatively complex and the cost is high. In addition, this type of drawer needs to drill straight holes and oblique holes, so two punching locators are required to guide the drilling, further increasing the installation cost.

[0003] Therefore, further improvements are necessary. Summary of the Invention

[0004] The purpose of the present invention is to provide a punching locator with simple structure, low cost, good versatility and strong practicality, so as to overcome the shortcomings of the prior art.
