In the concrete implementation, the cotter module is used as a main working module, after the fixing module fixes the head of the cotter, the cotter long tail side 1002 is inserted into the cotter long tail guide hole 201, so that the tool is prevented from deviating, then force is applied to the middle between the first handle 4 and the second handle 9 to clamp, the cotter long tail side 1002 deviates to one side under the action of the cotter long tail guide hole 201, so that the tail part is pulled to open a gap;

it should be noted that, the method of the present invention is different from the existing method, and the existing method is: the split pin head is fixed by using sharp-nosed pliers or other tools, the long tail side of the split pin is broken into proper angles for several times by using the sharp-nosed pliers, then the short tail side of the split pin is broken into proper angles, the angle size cannot be fixed, and when the split pin head is fixed by using other tools, the tail part of the split pin is opened (namely, the split pin is broken) so that the possibility of movement (because only one end is fixed) exists, and the split pin is not attached to a fixed part when the split pin head is finally fixed, so that the possibility of movement exists.

After the two handles are continuously engaged, a 60-degree sharp angle of the cotter module penetrates into the middle of the cotter (namely a gap between the cotter short tail side 1003 and the cotter long tail side 1002), because the fixing module 1 fixes the relative position of the cotter and the tool, in the process of clamping the two handles, the cotter long tail guide hole 201 guides the direction of the cotter, the cotter short tail side 1003 enters the other side of the cotter module 2 and is provided with the cotter short tail guide groove 202, the cotter short tail side 1003 on the other side of the cotter moves outwards along the cotter short tail guide groove 202, namely performs opening movement, so that the two tails of the cotter are uniformly pulled to the two sides to form an included angle of 60 degrees, and the opening is up to a bolt or a shaft where the cotter is located, so that the cotter tightly adheres to the bolt or the shaft, and the cotter is prevented from moving on the bolt or the shaft.

In order to understand the technical solution of the present invention more clearly, the following describes the installation operation process of the present invention.

Firstly, for a cotter 10 inserted into a mounting hole of a fixed part (such as a bolt or a shaft, for example, a fixed shaft shown in fig. 4), placing a cotter head 1001 into a cotter fixing groove 101 of a fixing module 1, aligning a cotter long-tail side 1002 with a cotter long-tail guide hole 201 of a cotter module 2, moving a first handle and a second handle in opposite directions to realize engagement, so that the cotter is fixed end to end, and the problem that the cotter is easy to rotate on the fixed part (such as a bolt or a shaft) is solved;

then, applying force on the first handle and the second handle to enable the two handles to rotate around the handle pin shaft 5 and move oppositely, so that the cotter pin short tail side 1003 enters the cotter pin short tail guide groove 202 of the tail opening module 2;

and then, force is continuously applied to the two handles, the two handles rotate around the handle pin shaft 5 and are continuously engaged, the long tail side and the short tail side of the cotter pin are respectively split along two inclined planes at an angle of 60 degrees of the splitting module until the tail end of the cotter pin 10 is split to the position of a fixed part (such as a bolt or a shaft), and the cotter pin is installed.

Compared with the prior art, the utility model provides a standardized installation device of split pin has following beneficial effect:

1. the utility model discloses a fixed module and these two kinds of modules of division of tail module can use in the fixed occasion of all split pins, have solved in ordinary installation split pin easy rotation and the installation effectiveness that leads to on fixed part (for example bolt or axle type) low to and the difficult problem of splitting of split pin tail that exists, can improve work efficiency by a wide margin.

2. The utility model discloses use the division module to inject the angle of pulling of split pin afterbody for it is unified that every split pin is pulled the angle, and avoided the injury that the in-process that tools such as present use hammers strikeed caused the split pin, install the split pin fast, standardly.

3. The utility model discloses a these two kinds of modules of fixed module and division module adopt the modularized design, through the module of changing different models, can adapt to the user demand of the split pin of different specification models, and the module is changed conveniently, reduces the quantity and the weight that the staff carried the instrument.

4. The utility model discloses, through using fixed module and division tail module, disposable can reach fixed split pin head, pull out the split pin afterbody to regulation angle, makes the split pin firmly install the effect on fixed part (for example the working shaft), can change the module of different models according to split pin size, installation situation scheduling problem, reaches the best adaptation state.

5. The utility model discloses, can be to the quick, standard installation of split pin, the low problem of installation effectiveness because the rotation brought when having solved the split pin installation effectively to and the split pin afterbody can't be pulled open, pull open the position not right that the angle is unified and the afterbody is pulled open, the split pin is in the emergence of the play condition in the mounting hole of the fixed part. Use the utility model discloses afterwards, have the characteristics of guaranteeing cotter installation quality uniformity.

To sum up, compared with the prior art, the utility model provides a pair of standardized installation device of split pin, its structural design science, a standardized installation device of split pin for in the installation operation of split pin, its structural design science, a during the installation operation of split pin, can effectively solve because the split pin easily rotates and have the problem that the installation effectiveness is low on fixed part, and there is the difficult problem of pulling open of split pin tail, conveniently, install the split pin reliably, show the installation work efficiency who improves the split pin, reduce staff's intensity of labour, and great practical significance is realized.

For convenient use, the utility model is designed as a hand-held using device. Through the inspection, the utility model discloses can satisfy the installation use of equidimension split pin not, effectively solve to present various split pins in the installation because of the rotation of split pin on the fixed part and the installation effectiveness low problem that leads to and the afterbody is pulled open inconvenient, is pulled open the back angle degree and is not unified, and the afterbody is pulled open the problem of back split pin drunkenness on fixed part (being axle or bolt).

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
