     Accordingly, there is a clearly felt need in the art for a two axis micro-adjusting device with a single locking mechanism, which allows two axis adjustment of a first object, such as an arrow rest relative to a second object, such as an archery bow to be secured with a single locking mechanism, such as a screw. 
     SUMMARY OF THE INVENTION 
     The present invention provides a two axis micro-adjusting device with a single locking mechanism, which allows two-axis adjustment of an object to be secured with a single locking mechanism. The two axis micro-adjusting device with a single locking mechanism (two axis adjustment device) preferably includes a mounting base, a first axis adjustment housing, a first axis adjustment bar, a second axis adjustment nut, a first axis adjustment screw, a second axis adjustment screw and a locking fastener. The mounting base includes a second axis housing and an attachment bracket extending from a bottom of the second axis housing. The attachment bracket is attached to a second object, such as an archery bow. The second axis adjustment nut is slidably retained in the second axis housing. The first axis adjustment housing is slidably retained on a top of the second axis housing and the second axis adjustment nut is secured with the locking fastener. The first axis adjustment housing includes an adjustment bar guide opening, and a screw pedestal for rotatably retaining the first axis adjustment screw. Rotation of the first axis adjustment screw causes axial movement of the first axis adjustment bar. Rotation of the second axis adjustment screw causes axial movement of the second axis adjustment nut. The first object, such as an arrow rest is secured to an end of the first axis adjustment bar with a fastener or the like. Once the first and second axis adjustments are made through the first and second axis adjustment screws, the locking fastener is tightened to lock the first and second axis adjustments. 
     Accordingly, it is an object of the present invention to provide a two axis micro-adjusting device with a single locking mechanism, which allows two axis adjustment of a first object, such as an arrow rest relative to a second object, such as an archery bow to be secured with a single locking mechanism, such as a screw.
