2. The surface cleaning device with the light weight and the convenient use as claimed in claim 1, wherein the transverse part is provided at both ends thereof with rotating shafts protruding outwards, the floor brush is provided with shaft holes for the insertion of the rotating shafts, the elastic member comprises a torsion spring arranged at the rotating shafts, and the torsion spring enables the machine body in the working state to be supported through the adapter.

3. A surface cleaning apparatus as claimed in claim 1, wherein the transverse portion is provided at each end with an outwardly projecting shaft, the floor brush is provided with a shaft hole into which the shaft is inserted, the resilient member comprises a spring disposed between the adapter and the floor brush, one end of the spring contacts the adapter and the other end contacts the lower casing, and the spring causes the body in operation to be subjected to an upward force by the adapter.

4. A surface cleaning apparatus as claimed in claim 2 or claim 3, wherein the resilient member comprises a damping block located within the scrubbing brush, and the adaptor includes a projection located above the damping block, the projection abutting the damping block to support the body in the operating condition.

5. A surface cleaning apparatus as claimed in claim 4 wherein there are two bosses located on the underside of the two shafts respectively, and two damping blocks located below the two bosses respectively; and/or the lower shell is provided with a mounting groove positioned below the boss, and the damping block is arranged in the mounting groove and protrudes upwards out of the mounting groove.

6. A surface cleaning apparatus as claimed in claim 1, wherein the transverse portion has outwardly projecting shafts at each end, the floor brush has shaft holes for the shafts to be inserted into, the resilient member includes a damping block disposed in the floor brush, and the adapter has a boss located above the damping block and abutting against the damping block to support the body in an operating state.

7. The surface cleaning device with convenient use according to claim 6, wherein the bosses are provided with two bosses which are respectively positioned at the bottom sides of the two rotating shafts, and the damping blocks are provided with two bosses which are respectively positioned below the two bosses; and/or the lower shell is provided with a mounting groove positioned below the boss, and the damping block is arranged in the mounting groove and protrudes upwards out of the mounting groove.

8. The portable surface cleaning device as claimed in claim 1, wherein the lateral portion has a shaft hole for inserting the shaft at both ends, the floor brush has a forward elastic member and a reverse elastic member corresponding to the same shaft, the forward elastic member makes the body receive a forward acting force through the adapter when the body in the working state rotates backward, and the reverse elastic member makes the body receive a damping force through the adapter when the body in the working state rotates backward.

9. A surface cleaning apparatus as claimed in claim 8, wherein the positive resilient member is a tension or torsion spring; and/or the reverse elastic member is a torsion spring or a compression spring.

10. A surface cleaning apparatus as claimed in claim 1, wherein the bottom end of the body is provided with a socket which engages with the vertical portion, the vertical portion extends into the socket, and a snap-fit arrangement is provided between the vertical portion and the socket to retain the vertical portion in axial alignment with the socket.
