An impact block connecting bolt is arranged at the upper middle position of the connecting block, and a bone hammer groove is arranged at the middle position of the front surface of the hammer head connecting block, and a replaceable bone hammer impact block is arranged above the impact block connecting bolt, The manual telescopic rod is installed on the right side of the hammer head connection block, and the hammer head connection bolt is arranged on the left side of the manual telescopic rod close to the right side of the hammer head connection block, and the telescopic rod adjustment knob is installed above the manual telescopic rod Close to the right side of the replaceable bone hammer impact block, the anti-slip and anti-corrosion protective sleeve is installed on the outside of the manual telescopic rod near the right side of the telescopic rod adjustment knob.

Preferably, the replaceable bone hammer impact block is fixedly connected to the hammer head connecting block through impact block connecting bolts.

Preferably, there are two replaceable bone hammer impact blocks in total, and the two replaceable bone hammer impact blocks are respectively installed at the upper and lower ends of the hammer head connection block.

Preferably, the hammer head connection block is fixedly connected to the manual telescopic rod through hammer head connection bolts.

Preferably, the telescopic rod adjustment knob is fixedly connected to the manual telescopic rod through threads.

Working principle and process of the utility model:

After the utility model is installed, select a suitable hammer head connection block according to the patient's condition, connect the hammer head connection block with the manual telescopic rod through the hammer head connection bolt, and then select a suitable replaceable bone hammer impact block, through the impact block The connecting bolt connects the replaceable bone hammer impact block with the hammer head connection block, and the length of the manual telescopic rod is adjusted through the telescopic rod adjustment knob.

The beneficial effects of the utility model:

The utility model has a scientific and reasonable structure, and is safe and convenient to use. It is equipped with a replaceable hammer head and impact block, which can replace the hammer head and impact block of different volumes according to the condition and needs of different patients, making the treatment and inspection more accurate. The manual telescopic rod can adjust the length of the bone hammer by adjusting the knob of the telescopic rod according to the actual situation, which solves the problem that the traditional bone hammer cannot replace the hammer head and adjust the length of the hammer shaft, and avoids the traditional bone hammer with single function and inconvenient use The problem.
