[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Please refer to Figure 1 and Figure 4The embodiment of the utility model provides a screw-on tool holder installation structure for an oscillating knife, including a rod body 112, a tool holder 13, a cutting knife 12, a tool locking screw 26 and other components. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, a D-shaped snap ring 113 is provided on the outer wall of the rod body 112, and a flat surface is provided on one side of the D-shaped snap ring 113. A rod body knife groove 110 is provided at the end of the rod body 112.

[0020] like Figure 1 and Figure 3 As shown, a clamping block 131 is provided at one side of the rod entrance at the upper end of the tool holder 13 , so that the rod entrance of the tool holder 13 forms a D-shaped clamping socket 132 .

[0021] Better, such as Figure 3 As shown, the tool holder 13 may include a tool holder cylindrical portion 133 and a tool holder block portion 134. The tool holder block portion 134 is connected to one side of the tool holder cylindrical portion 133, and a D-shaped bayonet is provided at the tool holder cylindrical portion 133. A tool holder tool groove 130 is provided between the inside of the tool holder cylindrical portion 133 and the tool holder block portion 134.

[0022] like Figure 4 As shown, the cutter 12 is inserted into the cutter holder knife groove 130 inside the cutter holder 13 and the rod body knife groove 110 of the rod body 112, and the knife locking screw 26 is installed on one side of the cutter holder 13 and inserted into the inside of the cutter holder 13 to lock and fix the cutter 12.

[0023] When installing the knife, the D-shaped snap ring 113 of the rod body 112 needs to be aligned with the D-shaped slot 132, and then the end of the rod body 112 and the D-shaped snap ring 113 are inserted into the interior of the knife clamp 13. Then the knife clamp 13 needs to be rotated a certain angle (such as 90 degrees). At this time, the D-shaped snap ring 113 can be misaligned with the clamp block 131, and the D-shaped snap ring 113 and the clamp block 131 are engaged, so that the rod body 112 and the knife clamp 13 are rotationally connected. Subsequently, the cutter 12 is inserted into the knife groove of the knife clamp 13 and the rod body 112, and finally the cutter 12 is locked by the knife locking screw 26.

[0024] like Figure 4 and Figure 5 As shown, the screw-on tool clamp mounting structure may also include a fixed tool seat 14, which may be mounted on the inner bottom end of the vibrating tool outer cylinder 1 of the vibrating tool via a tool seat screw 10. The fixed tool seat 14 may position the rotation angle of the tool clamp 13 and the cutter 12 to prevent unnecessary deflection of the tool clamp 13 and the cutter 12.

[0025] In summary, the utility model has a simple structure and a reasonable design. The tool clamp is connected to the rod body by a rotating clamping method, which can prevent the tool clamp from detaching from the rod body in the axial direction and avoid the risk of the tool falling off.

[0026] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
