One end of the prop 11 is fixed to the strut 12 pivotally, and the other end of the prop 11 is bended and is fixed to the lever 32.
There is a hole in the prop which can be gone through by the lever 32. When rotated, the lever 32 can bring the mounting assembly 1 retract or deploy.
That is to say, the latch bar 131 on the longitudinal face of the curved elongated member will be pulled out of the catch slot 21 and unlock the glider rocker when the mounting assembly 1 is in the retract position; conversely, the latch bar 131 on the longitudinal face of the curved elongated member 13 will be inserted into the catch slot 21 and lock the glider rocker.

The cross section of the lever 32 is square but not limited to square which can drive the movement of the locking mechanism.
A handle 3 1 is connected to the lever 32, and just by operating the handle 3 1 it can easily lock and unlocked the glider rocker.
The operation of the locking mechanism will now be described. When it is desired to lock the glider rocker in a particular position within its range of movement relative to the stationary base 5, as shown in FIG. 9, the lever 32 is manipulated by the handle 31 to bring the mounting assembly 1 to move until the latch bar 131 on the longitudinal face of the curved elongated member 13 is inserted into the catch slot 21 and lock the glider rocker. By this time the prop 11 and the strut 12 turn to a more straightened position, the cooperation of the blocking bar 133 on the curved elongated member 13 and the groove 121 of the strut 12 can support the strut 12 and avoid the excess offset of the strut 12, which makes the glider rocker much safer and more stable.
When it is desired to unlock the glider rocker with the mounting assembly in retracted position, as shown in FIG. 8, the lever 32 is manipulated by the handle 31 to bring the mounting assembly 1 to move until the latch bar 131 on the longitudinal face of the curved elongated member 13 are raised off from the catch slot 21 of the bearing bracket 2 and therefore the rocking and gliding motion of the glider rocker can take place without any interference from the locking mechanism.
The bounce of the restoring spring 15 can bring the latch bar 13 1 get away from the catch slots 21 of the bearing bracket 2 easily, in other words, it is easy and flexible to unlock the glider rocker.
It will be evident to those skilled in the art that changes and modifications may be made therein without departing from the essence of this invention. All such modifications or variations are believed to be within the scope of the invention as defined by the claims appended hereto.
