[0024] A high-precision handle for an electric tool. The electric push rod 6, the resistance spring 17 and the telescopic cylinder body 19 used in the present application are all products that can be directly purchased on the market. The principles and connection methods thereof are all prior arts well known to those skilled in the art, so they will not be described in detail here. The handle comprises a mounting seat 1, a fixing ring 2 is arranged on the inner bottom wall of the mounting seat 1, an adapting thread 3 is arranged on the inner side wall of the fixing ring 2, a fastening ring 4 is fixedly connected to the inner side wall of the mounting seat 1, and a groove 5 is arranged inside the fastening ring 4;

[0025] The electric push rod 6 is installed on the lower surface of the fastening ring 4. A resistance pad 7 is provided at one end of the electric push rod 6 away from the groove 5. A mounting ring 8 is provided inside the fastening ring 4. The left and right surfaces of the mounting ring 8 are fixedly connected with a clamping block 9. The clamping block 9 and the groove 5 are adapted to each other. The lower surface of the mounting ring 8 is fixedly connected with a fastening column 10. The outer surface of the fastening column 10 is provided with a mounting thread 11. The mounting thread 11 and the adapting thread 3 are adapted to each other. The top surface of the mounting ring 8 is fixedly connected with a connecting frame 12. The right side surface of the connecting frame 12 is fixedly connected with a handle body 13. The top surface of the handle body 13 is provided with an inlet Liquid cylinder 14, the outer surface of the handle body 13 is installed with an anti-slip sleeve 15, the back of the anti-slip sleeve 15 is fixedly connected to a limit frame 16, the outer surface of the limit frame 16 is provided with a rubber material, and the limit frame 16 is an aluminum product. The inner side wall of the handle body 13 is fixedly connected with a resistance spring 17 on both sides, and the right side surface of the resistance spring 17 is provided with a piston body 18, and the left side surface of the piston body 18 is provided with a telescopic rod. The upper and lower inner walls of the handle body 13 are all provided with a telescopic cylinder body 19, and the lower surface of the telescopic cylinder body 19 is provided with a buffer ring 20. First, align the mounting ring 8 and the clamping block 9 with the fastening ring 4 and the groove 5, so as to clamp. The block 9 will enter the inside of the groove 5, and the mounting ring 8 will also enter the inside of the fixing ring 2, and then the mounting ring 8 will be rotated 270 degrees, so that the mounting ring 8 and the clamping block 9 can be rotated on the lower surface of the fastening ring 4. At this time, the fastening column 10 and the mounting thread 11 will also be threadedly connected with the adapter thread 3, and the overall installation is relatively stable. Then, the top surface of the clamping block 9 is provided with an electric push rod 6 and a contact pad 7. When the electric push rod 6 is started, the electric push rod 6 can drive the contact pad 7 to move downward, so that the contact pad 7 will contact the top surface of the clamping block 9, and the mounting ring 8 can be stably installed as a whole, so that the mounting seat 1 and the connecting rod are fixed. The installation between the connecting frame 12 is relatively convenient and the operation speed is relatively fast. By opening the liquid inlet cylinder 14, hydraulic oil is added to the inside of the handle body 13, and then the anti-slip sleeve 15 can ensure that the user's hands are anti-slip. At the same time, the limiting frame 16 can enhance the limiting stability of the user. Then, when the mounting base 1 and the connecting frame 12 are used as a whole, the power tool will vibrate.

The contact area between the buffer ring 20 and the hydraulic oil becomes larger, so that the impact force of the vibration can be dispersed, and the overall buffering effect is better.

[0026] Working principle: When in use, first align the mounting ring 8 and the block 9 with the fastening ring 4 and the groove 5, so that the block 9 will enter the inside of the groove 5, and at the same time, the mounting ring 8 will also enter the inside of the fixing ring 2, and then rotate the mounting ring 8 270 degrees, so that the mounting ring 8 and the block 9 can rotate on the lower surface of the fastening ring 4. At this time, the fastening column 10 and the mounting thread 11 will also be threadedly connected with the adapter thread 3, and the overall installation is relatively stable. Then, the top surface of the block 9 is provided with an electric push rod 6 and a contact pad 7. When the electric push rod 6 is started, the electric push rod 6 can drive the contact pad 7 to move downward, so that the contact pad 7 will contact the block 9. On the top surface, the mounting ring 8 can be stably installed as a whole. By opening the liquid inlet cylinder 14 and adding hydraulic oil to the inside of the handle body 13, the anti-slip sleeve 15 can ensure that the user's hands are anti-slip. At the same time, the limiting frame 16 can enhance the user's limiting stability. Then, when the mounting seat 1 and the connecting frame 12 are used as a whole, the power tool will vibrate, and the hydraulic oil will move at this time. At the same time, the hydraulic oil will contact the piston body 18 and the buffer ring 20, and the contact area between the buffer ring 20 and the hydraulic oil will become larger, thereby dispersing the impact force of the vibration. The above is all the working principles of the present invention.
