Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example 1

As shown in fig. 1 and 2, the diamond combined tool comprises a tool handle 1 and a blade 2 which are separately arranged, a diamond tool block 3 is fixedly connected to the blade 2, and a connecting structure for adjusting the position of the blade 2 and locking the blade 2 to the tool handle 1 is arranged between the tool handle 1 and the blade 2.

Further saying in detail, connection structure includes connecting seat 4 that 1 tip of handle of a knife has in this embodiment, and connecting seat 4 has the spout that supplies blade 2 to slide, and connecting seat 4 has a plurality of threaded connection's screw 5, and each screw 5 homonymy sets up, and connecting seat 4 is used for conflicting blade 2 all passed to the inner of each screw 5. The inner end of each screw 5 is propped against the blade 2 to compress the blade 2 in the sliding groove, so that the purpose of locking the blade 2 is achieved, when the position of the blade 2 needs to be adjusted, each screw 5 is loosened, then the blade 2 is enabled to move in the sliding groove, when the blade 2 reaches the required position, each screw 5 is screwed again to lock the blade 2 again, and the position adjustment of the blade 2 is convenient.

The top of the groove wall of the sliding groove, which is far away from the screw 5 side, is provided with a pressing part 6 which is turned inwards and is abutted against the top of the blade 2, and the pressing part 6 prevents the blade 2 from being separated from the sliding groove, so that the cutting stability and the safety are ensured; the connecting seat 4 is provided with a cutting surface 7 which is used for connecting the screws 5 and is parallel to the chute wall, and the screws 5 are arranged in a line, so that the screws 5 have the same size, the manufacture is convenient, and the locking effect on the blade 2 is good.
