Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
Referring to fig. 1 to 3, the abrasion-free replaceable woodworking chisel of the present invention includes a woodworking chisel rod 1 and a woodworking chisel body 2 connected in sequence, wherein a woodworking chisel replacement blade 3 is detachably mounted on a mounting portion of the woodworking chisel body 2; after the cutting edge of the woodworking chisel replacing blade 3 is abraded, constructors can conveniently and quickly replace the woodworking chisel replacing blade 3 on a construction site; referring to fig. 4 and 5, a first step notch 4 is formed above the mounting portion of the woodworking chisel body 2, a first mounting block 5 is formed below the mounting portion of the woodworking chisel body 2, and the first step notch 4 and the first mounting block 5 preferably have a rectangular structure; referring to fig. 6 and 7, one end of the woodworking chisel replacing blade 3 is a blade end 31, the other end of the woodworking chisel replacing blade is a mounting end 32, a second step notch 7 is formed below the mounting end 32 of the woodworking chisel replacing blade 3, a second mounting block 8 is formed above the mounting end 32 of the woodworking chisel replacing blade 3, the first mounting block 5 is matched with the second step notch 7 in shape, and the second mounting block 8 is matched with the first step notch 4 in shape. When the installation structure is assembled, the first installation block 5 is arranged in the second step notch 7, the second installation block 8 is arranged in the first step notch 4, a plurality of installation holes 10 are formed in the second installation block 8, the second installation block 8 is installed on the first installation block 5 through screws in the installation holes 10, the head of the screw is arranged in the installation hole 10, and the exposed surface of the screw is lower than that of the installation hole 10. Simple structure and convenient assembly and disassembly.
In order to prevent the woodworking chisel replacing blade 3 from shaking left and right when in use; a positioning block 6 protrudes from the middle position of the top end of the first mounting block 5, a positioning groove 9 is further formed in the woodworking chisel replacing blade 3 at the position of the second step notch 7, and the positioning groove 9 is matched with the positioning block 6 in shape. After the assembly, the positioning block 6 is positioned in the positioning groove 9, so that the woodworking chisel replacement blade 3 is prevented from shaking left and right.
