The upper surface of sleeve B57 is provided with a slot 58, which is inserted into the slot 56.

[0035] Reference Figure 1 - Figure 3 The protective mechanism also includes a guide assembly 4, which includes a guide rod 41 for changing position. The guide rod 41 is fixedly connected to the outer wall of the fixed plate 3. A guide ring 42 for supporting the guide assembly 4 is fixedly connected to the right surface of the guide rod 41. A support column 43 is fixedly connected to the left surface of the guide ring 42. A moving rod 44 is elastically connected to the inner wall of the left side of the support column 43 through a compression spring 45. The moving rod 44 moves within the inner wall of the support column 43. When the sleeves A52 and B57 are installed, their right surfaces contact the moving rod 44, allowing for position adjustment of the sleeves A52 and B57.

[0036] Reference Figure 1 , Figure 2 , Figure 4 The mounting component 6 includes a positioning groove 61, which is formed on the front surface of the guide rod 41. The inner wall of the slide groove 53 is elastically connected to a slider 62 by a connecting spring 63. The slider 62 and the positioning groove 61 fit together to ensure the stability of the sleeve A52 and the sleeve B57 during installation.

[0039] Working principle: When using this device, first align the guide rod 41 with the slide groove 53 and insert it. During the insertion process, the inclined surface of the slider 62 will be squeezed, and the slider 62 will move forward to remove the obstruction and squeeze the connecting spring 63 to generate a reaction force. When the slider 62 and the positioning groove 61 are aligned, the reaction force of the connecting spring 63 will push the slider 62 out and lock it in the positioning groove 61, so as to realize the quick installation of the sleeve A52 and the sleeve B57. At this time, the moving rod 44 will contact the right surface of the sleeve A52 and the sleeve B57 due to the push of the compression spring 45.

[0040] Then, holding the main body 1 and handle 2, the drill begins. During drilling, flying debris will be generated. This debris will be blocked and collected by sleeves A52 and B57. As the drilling depth increases, sleeves A52 and B57 will gradually move towards the guide ring 42. During this movement, the moving rod 44 will be pushed and gradually retracted into the support column 43. The moving rod 44 will also compress the compression spring 45 to generate a reaction force. The reaction force of the compression spring 45 will push the moving rod 44 against sleeves A52 and B57, ensuring that sleeves A52 and B57 are always in contact with the wall surface, thus ensuring the stability of the protective effect.

[0041] After drilling is completed, close the machine body 1, then press down the locking block 56 to disengage it from the locking groove 58 and release the limit. Then rotate the sleeve A52 and sleeve B57 in the opposite direction to open them, so that the slide groove 53 and the guide rod 41 can be disengaged to complete the disassembly. Then pour out the impurities collected in the sleeve A52 and sleeve B57.
