DESC:AN EFFICIENT AND SAFE SPLIT PIN BENDING TOOL

TECHNICAL FIELD
[0001] The present disclosure, in general, relates to a bending tool. The present disclosure, particularly, relates to an efficient and safe split pin bending tool.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention.
[0003] Split pins, also known as cotter pins, are metal fasteners which are normally constructed from a piece of wire or metal. Split pins are made from thick wire and comes in a variety of sizes and styles. Split pins need to be strong enough to hold components in place, but flexible enough to be bent to secure the fastening. Split pins are typically made from aluminium, brass or stainless steel. Some pins feature zinc plating or have been galvanised.
[0004] Split pins are commonly used for securing bolts and nuts. In addition, split pins can be used to link different components together securely.
[0005] Split pins are integral to various manufacturing industries, particularly in automotive applications where they secure brake components, suspension parts, and steering linkages, ensuring these crucial elements remain securely fastened during operation.
[0006] Split pins find extensive use in agricultural machinery, where they secure components such as blades, shafts, and linkages, showcasing their ideal suitability due to their capacity to withstand vibrations and uphold a secure connection.
[0007] FIG. 1 illustrates an exemplary split pin. The split pin 100 primarily comprises a head 101, a body 102 and tines 103. The rounded end of the split pin 100 is usually called the head 101. The body 102 of the split pin 100 is the straight section between the head 101 and the tines 103. The body 102 passes through the holes in the component being secured. The split pin 100 has two tines 103 or legs that integrally extends from the body 102. These tines 103 are typically bent outwards after the pin 100 is inserted through the hole. The tines 103 could be straight or curved depending on the design of the split pin 100.
[0008] In the existing art, a set of pliers or additional tools are required to help bend the tines of the split pin.
[0009] One such technique to bend the split pin involves developing a pair of pliers designed to completely bend the tines of a split pin. However, using pliers to bend the tines requires increased force to hold the pins which, in turn, increases the risk of muscular fatigue and repetitive strain injuries. Also, by using a plier for bending the tines of the split pin, if the plier slips unexpectedly, one runs the risk of being injured.
[0010] Often times, split pin has to be provided in packed area between pieces of machinery. Providing split pins between packed pieces of machinery can indeed pose some challenges due to the limited space and accessibility. The tight spaces between components can make it difficult to bend the tines of the split pin. In such cases, temporarily moving or adjusting adjacent parts can create enough space to work with the split pins effectively. However, this may cause damage or misalignment to the components.
[0011] Accordingly, there is a need for a split pin bending tool that can be easily used in packed area between pieces of machinery.
