Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-2, a blade-replaceable trowel comprises a blade 1, a connecting piece 2, a handle 3 and a pressing handle 4;
a metal strip 101 is fixed on the blade 1, and sliding grooves 102 are respectively arranged on two sides of the metal strip 101;
the connecting piece 2 is composed of a handle part 201, a sliding groove part 202 and a connecting part 203 connected between the handle part 201 and the sliding groove part 202, the bottom of the sliding groove part 202 is provided with a sliding groove 204 matched with the metal strip 101, the top of the sliding groove 204 is provided with a hollow hole 205, two sides inside the sliding groove 204 are provided with sliding convex ribs 206 matched with the sliding grooves 102, and the metal strip 101 of the blade 1 is inserted into the sliding groove 204 of the connecting piece 2;
