## Background
FIELD OF THE INVENTION
The present invention relates to a snow removal apparatus and more particularly to a snow removal apparatus with the functions of shaving and pushing snow.
BACKGROUND OF THE INVENTION
In high latitude regions, the weather is cooler and the moisture is relative sufficient to snow, and the fallen snow is prone to become snow pack covered on the ground thereby interfering people in traffic or other situations. Thus, removing the snow is important for people living in these regions.
A user usually holds a shaft of a snow removal apparatus as a supporting point and using a blade portion of the apparatus formed at lower end thereof to shovel and remove the snow.
However, the conventional snow removal apparatus has following disadvantages: (i) for removing snow, a user needs to take a huge physical effort to use the tool, and the efficiency of removing snow is insufficient; and (ii) if the snow needs to be moved to a designated place, other tools such as a trolley must be used to achieve the action which is inconvenient and might cost unnecessary time and money. Therefore, there remains a need for a new and improved design for a snow removal apparatus to overcome the problems presented above.
SUMMARY OF THE INVENTION
The present invention provides a snow removal apparatus which comprises a main body, an engaging base, a shaft and two brackets. The main body has a curved blade which comprises a concave surface and a convex surface.

In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:
Referring to FIGS. 1 to 3, 5 and 7, the present invention provides a snow removal apparatus which comprises a main body (10), an engaging base (20), a shaft (30) and two brackets (40). The main body (10) has a curved blade (11) which comprises a concave surface (12) and a convex surface (13). The blade (11) comprises an opening (14) formed at an opposing side of the convex surface (13), and a connecting base (15) is formed and protrudes from an upper edge of the concave surface (12). The engaging base (20) is mounted on a central portion of the convex surface (13), and a connecting hole (16) and an engaging hole (21) are respectively formed on the connecting base (15) and the engaging base (20). The shaft (30) comprises a connecting end (31) and a holding end (32), and the connecting end (31) is selectively inserted and secured in the connecting hole (16) or the engaging hole (21) to connect the shaft (30) with the main body (10) thus allowing a user to shovel or push snow in different situations. Two lateral sides of the shaft (30) are respectively connected to two first ends of the two brackets (40) while two second ends of the two brackets (40) are respectively connected to the main body (10) thereby enhancing the structural strength and allowing the main body (10) and the shaft (30) to endure more pushing or pulling force, and wherein the connections between the two brackets (40) and the main body (10) and between the two brackets (40) and the shaft (30) are detachable.
Wherein a bottom portion of the connecting base (15) located on the concave surface (12) is formed in a taper shape, wherein a tip end of the bottom portion is located at an edge of the concave surface (12) and an expanded end thereof is located at a central portion of the concave surface (12).
