Description of the Related Art Conventionally, as an apparatus for fixing an electronic component to a printed circuit board or the like, there is an apparatus as shown in FIGS. 5 to 6, a pair of electronic component fixing blocks 1 provided with various mechanisms, for example, for bending and fixing an electronic component, are provided on the anvil main body 2 so as to be able to freely approach and separate from each other along the direction of insertion pitch of the electronic components. The two electronic component fixing blocks 1 are connected to a first gear 4 via a feed screw mechanism 3. The anvil main body 2 is provided on an elevating table of the elevating device 5, and the second gear 6 is moved to a position where the second gear 6 can mesh with the first gear 4 when the anvil main body 2 is at the origin position (lower end position). 7 and is provided. Further, a lock device 8 for preventing rotation of the first gear 4 is provided, and the lock device 8 is provided swingably on the anvil main body 2 and bites into the first gear 4 when the anvil main body 2 rises. The lock claw 9 is urged by a spring or the like, and the release block 10 releases the lock state of the lock claw 9 with respect to the first gear 4 at the origin position.

According to this configuration, the anvil main body 2 and the electronic component fixing block 1 are raised by the elevating device 5 to near the lower portion of the printed circuit board 12.
