Is there a "lock" position on on the 3 leg spread of this tripod?

So is this knob positioned on the lower, centre tube between the legs? Could you post photos of the Knob and where it fits to the tripod?
Most tripods have adjustment for 4 settings. Height, rotation, Tilt and mounting plate angle. We'll need to work out which one of these it's for. Height is usually a crank handle so it's possibly not that one. The other 3 are usually a bolt with a moulded cap to make turning it easier. Some tripods have a screw clamp on the body to lock the legs into the open or closed positions.
Comment below with more information and I'll try to help you more.

Is a manual or instruction leaflet really necessary ? Tripods are actually amazingly simple to use. You spread the three legs (three legs - 'tri'-pod) and place them firmly on level ground. Then you attach the camera, camcorder, spotting scope or whatever to the top, and use the equipment as desired.

Contact the importer or manufacturer, telling them the exact make and model number, plus a full description of the problem, with photos if possible. Alternatively, take it to a nearby camera shop or repair facility.

-It is possible that you are overloading the tripod, thus causing this problem (check specs on tripod model)
HOWEVER IF YOU AREN'T....Giotto uses (2) different leg lock designs..., quick release (normally adjusted by a socket wrench) or rotary (screw locks)!
- If tripod uses screw locks, sometimes foreign material gets into the mechanism and either damages it or prohibits from tightening!!!!!
Note: rotary locks are easy to maintain & if you need parts..., they are user replaceable and usually inexpensive! (contact Giottos distributor in the country you live in)!!!
BUT FIRST!!!! (often problem is caused by dirty lock mechanism)
-carefully unscrew the leg lock (that is slipping) until it separates from the leg higher leg section & carefully pull out the lower tube (at the top of the lower tube will be 'shims' that are part of the lock mechanism).
-Look closely at existing 'shims' do they show signs of cracking, of a build up of dirt, etc. (if damaged they will need to be replaced)
-if shims are undamaged..., use rubbing alcohol & a clean cloth to clean shims and both the tube they sit on and the inside of the tube they slide into.
-once both sides of the tubes and both male & female threads of the locking mechanism are cleaned..., place a light coating of a light oil into the threads (sewing machine oil, bike chain oil, etc)...., do not get oil on the shims!!!!!
-replace locking shims back into position and carefully slide leg tube back into place..., then screw locking collar on (this should not take any force..., if while threading lock collar back on..., it seems tight..., back off collar and check positioning of shims). Repeat procedure!!!
TEST RESULTS!!!
Note: in most cases with rotary locks, problem is purely a maintenance issue, cleaning usually fixes the issue!!!

To replace the batteries in each side of the 3-in-1 tripod light, you'll need to slide each light out of the central frame. Once each individual light is out on its own, you should be able to easily unscrew its bottom, giving you access to the battery compartment. Unlike the original Stanley tripod light, the actual tripod legs no longer hold the batteries.

On the original Stanley tripod LED light design, the black tripod leg tips simply unscrewed after you popped them out into the "stand" position. Much simpler to figure out.

Sorry, the mechanism and how it is put together should be repaired my Manfrotto. It has a one yar warranty when you bought it, and if you went to the Manfrotto website and registered it then the warranty is 3 years.

leg locking mechanism of the leg is failed,so replace the broken part to get it locked.

the plastic locks on our vivitor 980 tripod legs are broken now can i replace them. jan
