1 is an assembled perspective view illustrating a repair tip replacement type rework tool according to a first embodiment of the present invention, FIG. 2 is a view showing a state in which the protection cap shown in FIG. 1 is separated, FIG. 3 Is an exploded perspective view of the repair tip replacement type rework tool shown in Fig.

1 and 2, a repair tip replacement type rework tool 10 according to a first embodiment of the present invention includes a handle 11, a repair tip 12, a fixing block 13, a fastening member 14, And a protective cap 15.

The handle 11 is formed in a circular bar shape so that an operator can grip the handle 11, and an end portion of the handle 11 is depressed downward to form a seating portion 111 on which the repair tip 12 is seated.

An entrance opening 11a is formed at the end of the handle 11 so that the repair tip 12 is pulled into the seating portion 111 so that the upper surface of the seating portion 111 is exposed by the entrance opening 11a . At this time, the lead-in opening 11a has a structure in which not only the top but also the front side are opened.

The seating part 111 is formed so as to be recessed at a predetermined depth downward from the opening 11a for drawing and is formed such that the upper surface thereof has a flat surface so as to stably receive the repairing tip 12, 14 are inserted into the through holes 111a.

The repair tip 12 is inserted into the assembly hole formed in the housing of the connector and pushes out the terminal terminal inserted into the assembly hole to separate the body portion 121 and the end portion of the body portion 121, And a tip portion 122 integrally formed with the tip portion 122. The body part 121 is drawn in through the opening 11a for insertion and is seated on the upper surface of the seat part 111. [

The body 121 of the repair tip 12 is formed with a fastening hole 121a. At this time, since the peripheral shape of the repair tip 12 is formed to correspond to the internal shape of the end portion of the handle 11, the repair tip 12 is pulled through the pull-in opening 11a of the handle 11 The fastening holes 121a of the body portion 121 are automatically aligned with the fastening holes 111a formed in the seat portion 111. [

The fixed block 13 is fixed to the upper portion of the body portion 121 of the repair tip 12 in order to compensate the step between the upper portion of the upper end 11b of the handle 11 and the upper portion of the repair tip 12 mounted on the seat portion 111. [ Respectively.

Depending on the structure and shape of the repair tip 12, the body portion 121 is made in various thicknesses. When the body portion 121 of the repair tip 12 is relatively thin, the repair tip 12 and the upper end portion 11b of the handle 11 are positioned in a state where the repair tip 12 is seated on the seat portion 111 The repair tip 12 can flow during the terminal terminal detachment operation.
