Embodiment Construction

[0020] Figure 1 is an embodiment of a pin head manipulation tool. The metal rod 1 is a tapered cylinder made of stainless steel or high-quality steel, with a diameter of 10 mm at the thin end, a diameter of 20 mm at the thick and short ends, and a length of 10 cm. On the different directions perpendicular to the metal rod 1 at one end of the metal rod 1, holes 4, 5 and 6 with a diameter of 3 mm, 4 mm and 5 mm at a distance of 5 mm are drilled, and a diameter of 10 mm is drilled at the other end of the metal rod 1. The shank hole 3 of millimeter is crossed the shank hole 3 with the cylindrical steel material that is 10 centimeters long as the bar handle 2 that rotates by hand.

[0021] After the pin is penetrated into the pin, generally 10-20 mm remains, and the remaining pin head is inserted into the pin head through-holes 4, 5, 6 corresponding to the diameter of the pin head, and the handle 2 is turned with both hands or with one hand, and the pin can be removed. Head bendin...

Abstract

The invention provides a stem knob operating tool used in a narrow space. The tool consists of a metal rod and a rod handle, wherein a stem knob through hole through which the stem knob can pass is formed at one end of the metal rod; the stem knob through hole is vertical to the metal rod; a rod handle through hole through which the rod handle can pass is formed at the other end of the metal rod; the rod handle is vertical to the metal rod; the metal rod can be a conical cylinder and also can be a flat cube structure; a bell-mouthed obliquely guiding passage communicated with the stem knob through hole can be formed on the side face of the metal rod; a sawtoothed groove or a stepped groove can be formed at the top end of the metal rod; and the metal rod can be also in a curved shape. The stem knob operating tool can be used in the narrow space, can bend and restore stem knobs with various sizes and does not damage surrounding parts, wherein the bending degree is high.

Description

technical field [0001] The invention belongs to the technical field of operating tools in narrow and complicated spaces, and in particular relates to an operating tool capable of bending or restoring the exposed pin heads of pins in a narrow space without damaging surrounding components. Background technique [0002] Pins are a type of fasteners and connectors. In many complex mechanical equipment, pins are usually used to fix or reinforce installation parts. When the pin is fixing other fasteners, the pin head is exposed, and tools need to be used to bend it. During disassembly, it is necessary to restore the pin head. When the space is large enough, it can be operated by using ordinary wrenches, pliers, hammers and other tools. However, in a narrow space, especially when the surrounding components are easily damaged, if the above-mentioned tools are used, not only the operation is difficult, but also because the swing of the operating tool is too large, it is easy to cau...
