具体实施方式Detailed ways

如附图所示，本发明在电锤工具的壳体1尾部两内侧孔与“c”形电锤手柄4的两杆端部间，分别装有由一对永久磁铁2和3、7和6构成排斥型磁性弹簧，螺钉5分别穿过电锤工具的壳体1两内侧孔的导向槽，固定在“c”形电锤手柄4的两杆侧面，螺钉5和导向槽形成滑动配合。排斥型磁性弹簧用于吸收运行中因设备产生的振动。As shown in the drawings, the present invention is equipped with a pair of permanent magnets 2, 3, 7 and 6 constitutes a repelling magnetic spring. The screws 5 pass through the guide grooves of the two inner holes of the shell 1 of the electric hammer tool respectively, and are fixed on the two sides of the "c"-shaped electric hammer handle 4. The screws 5 and the guide grooves form a sliding fit. Repulsive magnetic springs are used to absorb vibrations generated by equipment during operation.

所述的两对永久磁铁2和3、7和6能沿壳体1两内侧孔轴向相对移动，第一永久磁铁2和第三永久磁铁7分别用螺钉8固定在电锤工具的壳体1两内侧孔底部，第二永久磁铁3和第四永久磁铁6分别用销9固定在“c”形电锤手柄4的端面。The two pairs of permanent magnets 2 and 3, 7 and 6 can move relatively axially along the two inner holes of the housing 1, and the first permanent magnet 2 and the third permanent magnet 7 are respectively fixed on the housing of the electric hammer tool with screws 8 1. At the bottom of the two inner holes, the second permanent magnet 3 and the fourth permanent magnet 6 are respectively fixed on the end face of the "c" shaped electric hammer handle 4 with pins 9.

所述的永久磁铁为单极永久磁铁或多极永久磁铁。The permanent magnets are single-pole permanent magnets or multi-pole permanent magnets.

所述的“c”形电锤手柄4的两杆侧面分别开有多个螺纹孔能与螺钉5配合，调整排斥型磁性弹簧的不同的排斥力。The sides of the two rods of the "c" shaped electric hammer handle 4 are respectively provided with a plurality of threaded holes which can cooperate with the screws 5 to adjust the different repelling forces of the repelling magnetic spring.

本发明工作原理如下：The working principle of the present invention is as follows:

如附图所示，当锤钻工作时，由于巨大的冲击力，振动会从冲击机构传到电锤工具的壳体1，因为“c”形电锤手柄4仅通过螺钉5与电锤工具的壳体1相连接及它与电锤工具的壳体1不再有直接的连接点，因此，极大地减小“c”形电锤手柄4相对电锤工具的壳体1的振动，此外，由于壳体1与“c”形电锤手柄4的两个端部间有两对永久磁铁2和3、7和6构成的排斥型磁性弹簧，可吸收运行中因设备产生的振动。As shown in the figure, when the hammer drill is working, due to the huge impact force, the vibration will be transmitted from the impact mechanism to the shell 1 of the electric hammer tool, because the "c" shaped electric hammer handle 4 is only connected with the electric hammer tool by the screw 5 The housing 1 of the electric hammer tool is connected and it no longer has a direct connection point with the housing 1 of the electric hammer tool, therefore, the vibration of the "c"-shaped electric hammer handle 4 relative to the housing 1 of the electric hammer tool is greatly reduced, and in addition Because there are two pairs of permanent magnets 2 and 3, 7 and 6 between the housing 1 and the two ends of the "c"-shaped electric hammer handle 4, the repulsive magnetic springs can absorb the vibration generated by the equipment during operation.

上述具体实施方式用来解释说明发明，而不是对本发明进行限制，在本发明的精神和权利要求的保护范围内，对本发明作出的任何修改和改变，都落入本发明的保护范围。The above specific embodiments are used to explain the invention, rather than to limit the present invention.
