The inner wall of the mounting base has a sliding groove, and several displacement blocks are slidably connected to the inner wall of the sliding groove. Several sliding rods are fixedly connected to the outer walls of each displacement block. Buckles are fixedly connected to the outer walls of each displacement block. A push sleeve is slidably connected to the outer wall of the mounting base, and several transmission grooves are formed on the inner wall of the push sleeve. An installation groove is formed on the inner wall of the mounting base, and an impact head is slidably connected to the inner wall of the installation groove. A retaining groove is formed on the inner wall of the impact head. Springs are fixedly connected to the outer walls of each displacement block.

[0008] Furthermore, the inner walls of several transmission grooves are slidably connected to the outer wall of the slide rod, and the inner wall of the slot is slidably connected to the outer wall of several buckles.

[0009] Furthermore, the inner wall of the threaded groove is provided with a protective mechanism, which includes a rotating ring, and the inner wall of the rotating ring is kinetically connected to the inner wall of the threaded groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model features a snap-fit ​​mechanism that allows the push sleeve to be pushed upwards. The push sleeve causes several sliding rods to shift, which in turn causes displacement blocks to shift. These displacement blocks then cause the snap-fit ​​mechanisms to shift, bringing the snap-fit ​​mechanisms closer together and compressing the springs. During this process, the snap-fit ​​mechanisms no longer hold the impact head in place, allowing the impact head to be pulled out of the mounting slot for disassembly. A new impact head can then be installed and the push sleeve released. This design enables quick and convenient disassembly and replacement of the impact head, preventing excessive wear and tear from prolonged use that could affect the normal operation of the equipment and significantly improving its versatility.

One end of the several connecting blocks 308 can only rotate in a fixed position within the limiting ring 310.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, they can directly grasp the screwdriver body 1 and use it by striking one end of the impact head 209 with the aid of other tools. During this process, the rotating ring 301 can be rotated clockwise. The rotating ring 301 will drive several connecting rods 302 to rotate and rise around it. The connecting rods 302 will drive the fixed ring 303 to rotate and rise. The fixed ring 303 will drive the second fixed ring 304 to rise. The second fixed ring 304 will drive one end of several connecting rods 307 to move and rotate simultaneously. The connecting rods 307 will drive the connecting block 308 to rotate. The connecting block 308 will drive the protective baffle 309 to rotate until it is perpendicular to the screwdriver body 1. The protective baffle 309 will protect the hand from accidental misalignment and direct impact during the impact of the tool on the impact head 209. When the tool hits the surface of the protective baffle 309, the protective baffle 309 will rotate. The rotating coupling block 308 causes the coupling rod 307 to move and rotate. The coupling rod 307 then causes the displacement ring 306 to move, which in turn compresses the buffer spring 305. The buffer spring 305 cushions the impact. When the impact head 209 is worn excessively after long-term use, the push sleeve 206 can be pushed upwards. The push sleeve 206 causes several slide rods 204 to move, and each slide rod 204 causes the displacement block 203 to move. The displacement block 203 causes the latch 205 to move, and the latches 205 move closer to each other and compress the spring 211. During this process, the latches 205 will no longer hold the impact head 209, and the impact head 209 can be directly pulled upwards from the mounting slot 208 for disassembly and separation. Then, the new impact head 209 is reset and installed, and the push sleeve 206 is released. The latches 205 are then reset by the spring 211 to hold the impact head 209 and prevent it from moving.
