Second friction lock face 29 of degree.
Second friction lock face 29 is located at the rear end face of the upper hinged seat 21.Two first friction lock faces
28 are located at the rear end face of the lower hinged seat 22 and symmetrical along the center line of lower 22 rear end face of hinged seat, and each described first rubs
Locking face 28 is wiped both with respect to the centre indent of lower 22 rear end face of hinged seat.
During the operating stick 3 drives the upper hinged seat 21 to rotate, pass through first, second friction lock face
Mutual cooperation realize locking.
The position limiting structure two realizes friction lock using compatible friction lock face, comparatively structure designs more
Simply.
Preferably, the position limiting structure one and position limiting structure two are used cooperatively, realize locking.
Position limiting structure three: the support base 2 further includes end cap 210, and first pivot 23 is arranged in the end cap 210
Shaft end.The position limiting structure includes that quiet piece 212 of the limit of the 210 top two sides of end cap is arranged in and is arranged in the upper hinge
Limit motion block 211 on the rear end face of joint chair 21, the limit motion block 211 can be limited between quiet piece 212 at two and be moved.
The part that do not address in the utility model uses or uses for reference prior art and can be realized.
The above description is only the embodiments of the present invention, is not intended to limit the utility model.For this field
For technical staff, various modifications and changes may be made to the present invention.All institutes within the spirit and principle of the utility model
