BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a wood planing machine, particularly to one having both manual and automatic planing wood function.
2. Description of the Prior Art
Since most part of wood is warped before being planed; therefore, when wood is to be planed with parallel precision, firstly, a hand press wood planer has to be used to have the wood planed to form a first flat surface as a criterion and then, an automatic wood planer is employed to carry out automatic feeding and plane the wood to form a second flat surface for enhancing parallel precision of the wood.
However, the planing wood method mentioned above has the following defects:
1. It is impossible to plane a warped wood and form parallel precision of the wood by singly employing an automatic wood planer; therefore, a consumer has to purchase two kinds of wood planers, thus high in purchasing cost;
2. The cutting tool of the hand press wood planer is installed beneath the wood, so the wood is likely to spring back and cause danger;
3. In case the wood is too thin, when carrying out planing wood with a hand press wood planer, a user's hands are apt to be injured; and
4. The wood to be planed cannot be too long; otherwise, when a user's hands press the wood, application of force may be uneven and as a result, the feeding end and the discharge end of the wood will cause disparity.
Therefore, in view of above-mentioned drawbacks, the inventor of this invention thinks that it is necessary how to reduce purchasing cost for consumers and integrate the advantage of both the conventional manual wood planer and automatic wood planer to enhance safety in use of a wood planning machine and hence devises this invention.
