There are screws that come up through the bottom. You may have to remove the faucet to tighten it. While you have it out, throw it away and buy a new one.

We had this same problem. We twisted off the sprayer cap to access the diverter valve under the trigger. The nylon diverter was stuck down into the cavity and was not popping out when the trigger was released. We pushed it down several times with needle nosed pliers to release it then applied a drop of household oil lubricant with the valve pushed all the way in. Then pushed and released several times to work the lubricant around the sides of the valve. After re-assembly, the sprayer seems to work perfectly again.

Look under your sink. The house is caught on something like your drain or something under the sink..
