The RA must be in the center of the screw to give you adjustment in both directions.

Something inside the telescope broke.
Another "happy" Bushnell scope buyer. Never by a Tasco or Bushnell telescope. These are considered "toy" telescopes and are usually NOT suitable for Astronomy.
Read my tips on my profile page, or return the telescope to where you bought it.
I got a beautiful scope in a estate sale but it
The larger end is pointed UP, the diagonal and eyepiece go into the smaller end of the tube. Measure the hole, these come in .965, 1.25 and 2 inch sizes.
Many on line retailers sell these. Here is one retailer:

a diagonal check the size of the hole:

Not worth repairing-- a new focuser for your telescope would cost as much or more than the telescope-- unless you can find a discarded telescope of the same model..... for parts.
The eye piece keeps falling
There are several different types of eyepiece holders:
Set-Screw-- this is a small screw on the side of the diagonal that holds in the eyepiece.
Compression ring-- again a small set screw but a brass compression ring tightens onto the eyepiece.
Plain Compression Diagonal-- the diagonal is a tight fit to the eyepiece- try binding it slightly in to get a tighter fit.
Telescope is only good for viewing moon...help!!!
your scope is 565mm focal length with a 60mm objective which makes it f:9.5. (telescope focal length divided by lens diameter)
all this means that the optics are capable of viewing larger planets. nebula is a bit of a stretch. maybe under exceptionally dark skies with at least 30min. of dark adaptation. brighter objects like m42 or m31 should be visible, bear in mind that only very large telescopes will resolve the slightest hint of color in nebulosity. the rest of us are reserved to gray scale. i would suggest using a 26mm eyepiece plossl if available. next make sure your finding system is aligned to the scope. this is best done during the day at a distant object like a radio tower. center the object in the eyepiece then align the finder.
next get your self a good sky map like stellarium software a freebie and a fav. to ensure your looking at what you think your looking at.
a word on eyepiece selection. magnification is calculated by dividing the focal length of the scope by the focal length of the eyepiece. for instance the scope is 565mm the recommended eyepiece is 26mm so the magnification would be around 22x.
a rule of thumb for optics is about 50x per inch of objective. which means your scope is good for about 100x. so by the math you would use a 5.6mm e.p. to achieve 100x, however as optical powers increase field of view decreases making it difficult to find objects. find your object with a wide field e.p. then switch to a higher power to zoom in. if the image gets fuzzy at high power attempt to refocus, if it doesn't clean up either your asking a bit to much from the scope or seeing conditions in the upper atmosphere may not be ideal. what ever you do don't give up there are some amazing things to see out there.

You never told us what model number or telescope TYPE you own. Is this a refractor or a reflector. ???
If a REFRACTOR usually you have a diagonal, the diagonal goes into the focuser and then the eyepiece goes into the diagonal.
On a REFLECTOR the eyepiece goes directly into the focuser.
