FIG. 2
, another prior art paint brush comprises a handle
6
and an application head
7

SUMMARY OF THE INVENTION
It is therefore the primary objective of the present invention to provide a paint brush with an application head which can be replaced with ease and speed.
It is another objective of the present invention to provide a paint brush with an application head which can be replaced handily by a person without tainting the hands of the person.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a paint brush comprising a handle, a connection seat, an application head, and a pushing member. The handle has a grip portion and a connection portion extending from one end of the grip portion and haviving a receiving portion and a retaining slot in communication with the receiving portion. The connection seat is provided with a retaining member and a connection member. The connection seat is disposed in the receiving portion of the connection portion of the handle such that the retaining member of the connection seat is retained in the retaining slot of the connection portion. The application head is connected with the connection member of the connection seat. The pushing member is disposed in the connection seat for pushing the connection seat out of the receiving portion of the connection portion of the handle.
