By using above-mentioned technical proposal, the side surface of bolt contradicts on the side wall of groove, while the end of bolt is supported
It touches in the bottom of groove, and then the contact area between bolt and groove is larger, to improve between bolt and movable supporting leg
Contact area, it is noted that the frictional force between bolt and movable supporting leg.
The bottom of the further setting of the utility model, the groove is fixed with the first plastic deformation piece, first modeling
Property deformation sheet along groove length direction be arranged.
By using above-mentioned technical proposal, after bolt enters groove, the end of bolt is slowly rotated close to the bottom of groove
Portion；When the end of bolt contradicts on the surface of the first plastic deformation piece, bolt becomes the first plasticity during rotation
Shape piece slowly deforms upon；When bolt is rotated in the first plastic deformation piece to when cannot rotate, the friction between bolt and groove
Power increases, and then displacement is not susceptible between bolt and movable supporting leg.
The opposing sidewalls of the further setting of the utility model, the groove are respectively and fixedly provided with the second plastic deformation piece, described
Second plastic deformation piece is arranged along the length direction of groove.
By using above-mentioned technical proposal, the side surface of bolt makes the second plastic deformation piece that certain deformation occur, in turn
Displacement is not susceptible between bolt and movable supporting leg；Second plastic deformation piece does not prevent the end of bolt from contradicting at the bottom of groove
Portion.
In conclusion the utility model has the advantages that：
1, the lifting foot rest locking device of feet is easy to operate, and use is laborsaving；
2, the lifting tripod locking device structure intensity of feet is strong, has stronger anti-pressure ability；
3, the locking effect of the lifting foot rest locking device of feet is preferable, and lifting tripod is elevated to after certain altitude locking
