[0022] Reference Figure 1-3 A power tool connector sleeve comprises a connector sleeve 1 and an impact pin 3. The interior of the connector sleeve 1 is hollow and both ends are open. One end of the connector sleeve 1 is provided with a working head mounting hole 8, and the working head mounting hole 8 is used to install and limit working heads of different specifications. The other end of the connector sleeve 1 is provided with an impact pin groove connecting groove 9 matching the impact pin 3 and a sealing mechanism.

[0023] The connector swivel sleeve 1 plays a key role. It can be connected and loaded with various required working heads to achieve transmission with the cylinder, and at the same time plays the functions of sealing and limiting.

[0024] Furthermore, the sealing mechanism includes a sealing groove opened inside the connector sleeve 1, and a plurality of impact sub-grooves 11 are evenly spaced inside the impact member 3. The rear end of the connector sleeve 1 is provided with a plurality of impact sub-groove connecting grooves 9 that cooperate with the impact sub-grooves 11, and the rear end of the connector sleeve 1 is also provided with a plurality of cylinder circumferential corresponding holes 10.

[0025] The position and size of the connector swivel sleeve 1 and the impactor 3 are carefully designed to ensure that the impactor 3 can be effectively limited during operation and avoid damage to the axial seal.

[0026] Furthermore, a cylinder 2 is installed inside the connector sleeve 1, an impact hammer 4 is provided at the rear end of the cylinder 2, and a compressed air piston assembly 5 is installed at the rear end of the impact hammer 4.

[0027] The connector swivel sleeve 1 cooperates with the cylinder 2, the impact member 3, the impact hammer 4 and the air compressor piston assembly 5 to form a high-efficiency chiseling, crushing or drilling function, and has the advantages of novel and reasonable structure, stable and reliable performance and high use efficiency.

[0028] Furthermore, a first rubber member 6 and a second rubber member 7 are installed inside the sealing groove. The first rubber member 6 and the second rubber member 7 use O-rings to provide effective sealing when the impactor 3 is installed and prevent friction damage to the edge of the impactor 3.

[0029] Furthermore, an inner hole groove area 12 and an inner hole 13 are provided inside the impactor 3 , an equally divided hole 14 is provided at the lower end of the inner hole groove area 12 , and a working head mounting groove 15 is provided at the end of the impactor 3 .

[0030] In summary, the interior of the connector sleeve 1 is interconnected, and there are holes equally divided at a certain distance in the circumference, and a groove is set in the middle area of ​​the hole, and it is connected to the outer circumference, and parts with equally divided grooves are also set in the outer circumference. A working head mounting hole 8 is set at one end, so that it can be loaded and limit the working stroke of the working head required by different needs, and an impact sub-groove connecting groove 9 matching the impact sub 3 is set at the other end. The impact sub and the matching O-shaped or rectangular rubber part 2 can be combined inside it and then installed in the connector sleeve through the specific groove area so that the rubber part will not be damaged by the sharp edge of the hole, which can play a better role in sealing to prevent grease leakage and improve the working environment. In addition to ensuring that the corresponding hole 10 of the external cylinder circumferential direction matches the corresponding axial groove of the impact sub, it is particularly important to set the hole at a certain distance, which is necessary to ensure that the hole limits the working stroke of the impact sub 3 and that the axial rubber part is not damaged in the safe area. There is also a circumferential groove on the outside axial direction to install the O-ring to always keep the performance in the cylinder stable and reliable, which is of practical significance for improving efficiency, improving the environment, enhancing the use effect, and extending the life.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
