However, the lead fixing device of the electronic component according to the related art, which is configured as described above, has to adjust width of the vertical axis and the horizontal axis according to the lead insertion direction to the circuit board, so that it is difficult to quickly respond to the lead insertion direction of the electronic component. There was a problem.

In addition, since the lead fixing operation of the electronic component is performed while the frame is set to a certain height, the peripheral electronic components mounted on the double-sided circuit board are moved while the fixing and variable tanks move in the vertical and horizontal directions when working on the double-sided circuit board. There is a risk of damage, and there is a problem that can not respond quickly to the various lead pitch of the electronic component.

The present invention was devised to solve the above problems, and the jaw fixing the lead of the electronic component to the circuit board can be rotated and moved up, down, left and right, so that the work on the double-sided circuit board is easy and the initial preparation work It is an object of the present invention to provide a lead fixing device for an electronic component that enables easy time adjustment and height setting and enables quick response to various lead pitches and lead insertion directions of the electronic component.
