A sunshade base includes a base, a swivel seat to which a support tube of a sunshade is mounted, a retaining member fixed to the swivel seat, and a braking device. The swivel seat includes a flange rotatably received in a recessed portion of a top face of the base. The braking device is mounted in the base and includes a rod movable in the base and a braking arm having a first end fixed to the rod and a second end releasably engaged with the retaining member. The second end of the braking arm is biased to engage with the retaining member to thereby lock the swivel seat. The rod is operable to disengage the second end of the braking arm from the retaining member to thereby allow free rotational movement of the swivel seat relative to the base.

What is claimed is: 1. A sunshade base comprising: a base including a top face and a bottom face, each of the top face and the bottom face including a recessed portion with a through-hole extending between the recessed portions; a swivel seat including a flange rotatably received in the recessed portion of the top face of the base, the swivel seat further including an upper tubular section adapted for receiving a support tube of a sunshade and a lower tubular section extending through the through-hole, the lower tubular section including a lower end extending into the recessed portion of the bottom face of the base; a retaining member fixed to the swivel seat; a braking device mounted in the base, the braking device including a rod movable in the base and a braking arm having a first end fixed to the rod and a second end releasably engaged with the retaining member; and means for biasing the second end of the braking arm to engage with the retaining member to thereby lock the swivel seat; wherein the rod is operable to disengage the second end of the braking arm from the retaining member to thereby allow free rotational movement of the swivel seat relative to the base, with the rod including an upper end extending beyond the top face of the base, with a pedal being mounted to the upper end of the rod, and with said means for biasing the second end of the braking arm including an elastic element mounted around the rod. 2. A sunshade base as comprising: a base including a top face and a bottom face, each of the top face and the bottom face including a recessed portion, with a through-hole extending between the recessed portions; a swivel seat including a flange rotatably received in the recessed portion of the top face of the base, the swivel seat further including an upper tubular section adapted for receiving a support tube of a sunshade and a lower tubular section extending through the through-hole, the lower tubular section including a lower end extending into the recessed portion of the bottom face of the base; a retaining member fixed to the swivel seat; a braking device mounted in the base, the braking device including a rod movable in the base and a braking arm having a first end fixed to the rod and a second end releasably engaged with the retaining member; and means for biasing the second end of the braking arm to engage with the retaining member to thereby lock the swivel seat; wherein the rod is operable to disengage the second end of the braking arm from the retaining member to thereby allow free rotational movement of the swivel seat relative to the base, with the retaining member being a gear with a plurality of teeth on an outer circumference thereof, with the second end of the braking arm having a plurality of teeth for releasably engaging with the teeth of the retaining member. 3. A sunshade base comprising: a base including a top face and a bottom face, each of the top face and the bottom face including a recessed portion, with a through-hole extending between the recessed portions; a swivel seat including a flange rotatably received in the recessed portion of the top face of the base, the swivel seat further including an upper tubular section adapted for receiving a support tube of a sunshade and a lower tubular section extending through the through-hole, the lower tubular section including a lower end extending into the recessed portion of the bottom face of the base; a retaining member fixed to the swivel seat; a braking device mounted in the base, the braking device including a rod movable in the base and a braking arm having a first end fixed to the rod and a second end releasably engaged with the retaining member; and means for biasing the second end of the braking arm to engage with the retaining member to thereby lock the swivel seat; wherein the rod is operable to disengage the second end of the braking arm from the retaining member to thereby allow free rotational movement of the swivel seat relative to the base, with the swivel seat including an upper part having a first flange section from which the upper tubular section extends upward, with the swivel seat further including a lower part having a second flange section from which the lower tubular section extends downward, with the first and second flange sections being fixed together and forming the flange of the swivel seat. 4. A sunshade base comprising: a base including a top face and a bottom face, each of the top face and the bottom face including a recessed portion, with a through-hole extending between the recessed portions; a swivel seat including a flange rotatably received in the recessed portion of the top face of the base, the swivel seat further including an upper tubular section adapted for receiving a support tube of a sunshade and a lower tubular section extending through the through-hole, the lower tubular section including a lower end extending into the recessed portion of the bottom face of the base; a retaining member fixed to the swivel seat; a braking device mounted in the base, the braking device including a rod movable in the base and a braking arm having a first end fixed to the rod and a second end releasably engaged with the retaining members; and means for biasing the second end of the braking arm to engage with the retaining member to thereby lock the swivel seat; wherein the rod is operable to disengage the second end of the braking arm from the retaining member to thereby allow free rotational movement of the swivel seat relative to the base, with the lower end of the lower tubular section of the swivel seat further including outer threading and a nut engaged with the outer threading for restraining longitudinal movement of the swivel seat relative to the base. 5. The sunshade base as claimed in claim 1, with the through-hole further including a bearing receiving section for receiving a bearing through which the lower tubular section extends. 6. The sunshade base as claimed in claim 1, with the sunshade base further including two wheel assemblies, with the base further including two recessed sections each having an opening. 7. The sunshade base as claimed in claim 6, with each said wheel assembly including a handle, a shaft mounted to the handle, and at least one wheel mounted to the shaft, the handle including a support section having two sides, a bracket being pivotally connected to each said side of the support section and mounted to an inner wall of an associated one of the recessed sections, allowing each said handle to pivot in the associated recessed section between a storage position in which at least one wheel of each said wheel assembly does not contact the ground and an operative position in which at least one wheel of each said wheel assembly is located on the ground and, thus raise the base above the ground. 8. The sunshade base as claimed in claim 7, with said at least one wheel of each said wheel assembly being a caster. 9.
