An annular groove 6 is opened on the right side of the wall, an angle line 5 is set at the right end of the right sleeve 1, a pointer 20 is fixedly connected to the right side of 5 at the rear end of the sleeve column 16, and a fixing component is set at the top of the right sleeve 1. The fixing component includes a fixing plate 11, one side of the bottom end of the fixing plate 11 is fixedly connected to the top of the sleeve 1, and the other side of the bottom end of the fixing plate 11 is fixedly connected to an electric push rod 10. The driving end of the electric push rod 10 is fixedly connected to an anti-skid splint 12, and the shape of the anti-skid splint 12 and the annular groove 6 are matched, and the outer side of the bottom end of the sleeve 1 is fixedly connected to a support leg 3.

[0034] In addition, during use, the electric push rod 10 is started to move the anti-slip splint 12 upward, so that the anti-slip splint 12 leaves the annular groove 6, thereby releasing the limit on the sleeve 16, and then the sleeve 16 and the pointer 20 are rotated to make the pointer 20 point to the required angle, so that the angle of the sleeve 16 can be changed, and then the force of the knocking can be changed. Therefore, different forces can be used for knocking, and the angle is the same, the force generated is also consistent, which improves practicality and is suitable for various scenarios.

[0035] A sound transmission component is arranged on the outside of the sleeve 1, and the sound transmission component includes a rotating block 2, the inner wall of the rotating block 2 is slidably connected to the outer wall of the sleeve 1, the inner wall of the rotating block 2 is fixedly connected to the rear end of the paddle 14, and a microphone 15 is fixedly connected to the left side of the inner wall of the rotating block 2 corresponding to the paddle 14. The sound transmission component also includes a small speaker 9, the left end of the small speaker 9 is fixedly connected to the right end of the sleeve column 16, the small speaker 9 and the microphone 15 are signal-connected, the microphone 15 collects sound and plays the sound through the small speaker 9, the rear end of the spring 19 is fixedly connected to the trapezoidal block 13 and passes through the sleeve column 16, the trapezoidal block 13 is limited by the sleeve column 16, a paddle 14 is arranged above the trapezoidal block 13, and the rear end of the rotating block 2 is fixedly connected to a hammer 4.

[0036] In addition, due to the change in the angle of the sleeve 16, the angle of the trapezoidal block 13 will also change accordingly. When it is necessary to perform a knocking process, the knocking hammer 4 is held and lifted upward. At this time, the paddle 14 is also rotating and rising around the center line of the sleeve 16. When the paddle 14 contacts the trapezoidal block 13, resistance will be generated. When continuing to rise, the paddle 14 has elasticity, so the paddle 14 will be deformed, so that it comes to the top of the trapezoidal block 13 and produces a sound. The sound generated is transmitted to the small speaker 9 through the microphone 15, and the sound is played out to better remind the operator so that he knows that the knocking work is ready.

[0037] Working principle: First, during use, the electric push rod 10 is started to move the anti-skid splint 12 upward, so that the anti-skid splint 12 leaves the annular groove 6, thereby releasing the limit on the sleeve 16, and then the sleeve 16 and the pointer 20 are rotated to make the pointer 20 point to the required angle, so that the angle of the sleeve 16 can be changed, and then the force of the knocking can be changed. Therefore, different forces can be used for knocking, and the angle is the same, and the force generated is also consistent, which improves practicality. Due to the change of the angle of the sleeve 16, the angle of the trapezoidal block 13 will also change accordingly. When knocking is required, the knocking hammer 4 is held and lifted upward. At this time, the pick 14 is also rotating and rising around the center line of the sleeve 16. When The pick 14 will generate resistance when it contacts the trapezoidal block 13. When it continues to rise, due to the elasticity of the pick 14, the pick 14 will be deformed, so that it comes to the top of the trapezoidal block 13 and produces a sound. The sound generated is transmitted to the small speaker 9 through the microphone 15, and the sound is played out to better remind the operator so that he knows that the knocking work is ready. Then, the fixing rod 8 is pushed to squeeze the triangular block 18. Since the triangular block 18 is in contact with the trapezoidal block 13 and has a certain slope, the triangular block 18 and the trapezoidal block 13 will move inward, thereby releasing the limit on the pick 14, and the gravity of the knocking hammer 4 will move downward and rotate at the same time, thereby knocking the knocking object.
