Rapid taking-out device for clamping broken screws

Abstract

The invention provides a rapid taking-out device for clamping broken screws. The rapid taking-out device comprises a double-screw bolt, a sleeve, clamping parts and springs. The double-screw bolt comprises a fastening section, a locking section and an extruding section. The sleeve comprises a fixing section, a connecting section and a clamping cylinder. The double-screw bolt extends into the sleeve. An outer thread of the double-screw bolt cooperates with an inner thread of the sleeve to achieve thread fixing. Each clamping part is arranged in the clamping cylinder. The top ends of the clamping parts are limited at the bottom end of the inner thread of the sleeve, the springs are embedded into spring clamping openings of the two clamping parts, and thus the clamping parts and the clamping cylinder are arranged in a sliding manner. The rapid taking-out device is simple in structure, wide in use range and low in manufacturing cost, and the installing process is convenient. The structure of an original connecting component does not need to be destroyed, and the working structure is stable.

Description

technical field [0001] The invention relates to the field of screw clamping tools, in particular to a quick extractor for clamping broken screws. Background technique [0002] Screws are important connecting parts that make two or more parts rigidly connected, and each part is fixed by screw thread locking. During use, various components are affected by various factors. The screws are subjected to tension, torsion, and shearing forces, which cause the bolts to collapse, and some bolts will remain in the component, which cannot be directly removed with tools. There are many ways to take out the existing broken screws. You can use fire welding to melt the remaining screws in the components at high temperature. However, this method consumes oxygen and acetylene, and is easy to damage the components, so the original ones cannot be reused. The bolt hole can be directly chiseled out, which is also easy to damage the component and the original bolt hole; or use tool pliers to pick...

Problems solved by technology

During use, the components are affected by various factors, and the screws are subject to tension, torsion, shearing force, etc., causing the bolts to collapse, and some bolts will remain in the component, which cannot be removed directly with tools

There are many ways to take out the existing broken screws. You can use fire welding to melt the remaining screws in the components at high temperature. However, this method consumes oxygen and acetylene, and is easy to damage the components, so the original ones cannot be reused. The bolt hole can be directly chiseled out, which is also easy to damage the component and the original bolt hole; or use tool pliers to pick up the broken screw part, manually turn the broken screw and take it out. This method is less forceful and cannot be applied to Removal of larger size screws or larger torque screws

At the same time, there are still many ways to remove screws, but the existing methods have strong application limitations, and it is impossible to use special screw removal tools to quickly and easily remove broken screws
