Problems solved by technology

[0002] The positioning pin is a part that restricts the freedom of the object. When the body is connected by multiple parts, and each part needs to maintain an accurate position during processing and assembly, the positioning pin is often used for positioning. The positioning pin may be damaged during equipment maintenance. Disassemble and replace to ensure the accuracy of the workpiece position, and the positioning pin hole is divided into through hole and blind hole, often when pulling out the positioning pin embedded in the blind hole, it must be clamped and pulled out, in a small space Due to the limited space, it is impossible to use force when pulling out, or the activity space is limited, so that the positioning pin cannot be pulled out

Abstract

The invention discloses a pin puller for a blind hole positioning pin in a small space in a hardware tool. The pin puller comprises a handle shell. A working cavity and a first movable groove are formed in the handle shell, three faces of the working cavity are open, an arc-shaped movable block is arranged in the first movable groove in a reciprocating sliding manner, and threads are formed in the opposite side faces of the working cavity and the arc-shaped movable block; the pin puller can easily stretch into the small space through the flat and long handle shell, the arc-shaped movable block is ejected to move by rotating a hollow adjusting rod exposed at the tail to clamp the positioning pin, and a power source for pulling the positioning pin can be arranged outside the pin puller through the hollow adjusting rod; and a first arc-shaped clamping block is connected to the handle shell through threads, a second arc-shaped clamping block is connected to the arc-shaped movable block through threads, the arc-shaped clamping blocks can rotate while ascend in the process of pulling the positioning pin out, and space is reserved in the handle shell for ascent.
