Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In a particular embodiment, the present invention provides a cotter pin splitter. Referring to fig. 1 and 2, the structure of a cotter pin splitter according to an embodiment of the present invention is shown.
The invention provides a cotter pin splitter, which comprises: the piston rod 1, the guide sleeve 2, the connecting rod 3, the positioning pin 4, the main body 5, the rotating ring 6, the positioning ring 7 and the fixing rod 8; wherein,
the guide sleeve 2 is fixedly connected with the rotating ring 6 through a connecting rod 3;
a rear portion of the piston rod 1 is mounted within the guide sleeve 2 for movement back and forth and for rotation along the guide sleeve 2;
the rotating ring 6 is sleeved on the periphery of the middle part of the main body 5 and is positioned by the positioning ring 7; the rotating ring 6 and the main body 5 can rotate relatively;
the upper part of the main body 5 is provided with a positioning pin 4; the lower part of the main body 5 is provided with a hole arranged along the horizontal direction, and the fixing rod 8 penetrates through the hole and can move along the hole.
Further, the connecting rod 3 comprises a straight section arranged along the horizontal direction and an upward bent section connected with the straight section; the straight section is connected with the rotary ring 6, and the upward bending section is connected with the guide sleeve 2.
Preferably, the head ends of the piston rod 1 and the fixing rod 8 are provided with arc surfaces, and the tail ends of the piston rod 1 and the fixing rod 8 are provided with annular limiting protrusions.
Further, the positioning ring 7 is disposed at a lower position in the middle of the main body 5, and the top surface thereof is in contact with the bottom surface of the rotating ring 6.
In operation, when the cotter pin 10 is inserted into the round pin 9, the body 5 of the cotter pin splitting apparatus of the present invention is placed over the bottom of the round pin 9, the locating pin 4 is inserted into the round hole of the cotter pin 10, the position of the piston rod 1 is adjusted so that the plane of the front end of the piston rod is opposite to the plane of the longer rod of the cotter pin 10, the fixing rod 8 is held by one hand, the piston rod 1 is held by the other hand and rotated, so that the longer rod of the cotter pin 10 is bent to form an angle, or wrapped around the outside of the body 5, and then the position of the piston rod 1 is adjusted so that the piston rod 1 is opposite to the plane of the shorter rod of the cotter pin 10, the piston rod 1 is rotated in the opposite direction to the previous direction, so that the shorter rod of the cotter pin 10 is bent to form an angle, or wrapped around the outside of the body 5, i.e. the installation of the cotter pin 10 is completed, the two rods of the cott, the split pin 10 can be pulled to be separated from the round pin 9 by matching of a hand hammer, and the disassembly is finished.
