Structure for a hand trowel handle with adjustable rotational angle

A structure for a hand trowel handle with adjustable rotational angle on the grasping section includes a blade, a connecting section and a grasping section. The blades in different shapes and areas can be used. The connecting section and the base form one integrated body. The connecting section uses the base to connect with the tongue on the blade. Thus, the blades can be in different shapes and areas. The structure for the grasping section with adjustable rotational angle features in a connecting section, a grasping section, a spring and an adjustment knob. Among these components, the supporting end of the connecting section has a toothed ring and a shaft in the center of the toothed ring. At the end of the shaft, there is a screw section. The surface of the grasping section is made of soft and slip-proof material and matches the shape of human hand. Its front end has a toothed ring and its rear end has an accomodating hole. Inside the grasping section, there is a through-hole that runs through the toothed ring and the accomodating hole. The spring is set in the accomodating hole of the grasping section and worn on the shaft in the accomodating hole. The terminal of the spring is against the inner side of the accomodating hole. The adjustment knob is part of a terminal, which is inserted into the accomodating hole of the grasping section. The adjustment knob connects to the screw section at the end of the shaft through a terminal screw. By turning the adjustment knob, the angle between the grasping section and the blade can be adjusted. By tightening the adjustment knob, the toothed rings for both the grasping section and the connecting section can be matched.
