[0033] See attached document Figures 1 to 3As shown, this application embodiment provides an adjustable diameter fixing structure suitable for a large animal striking device, including a fixing base 1, a fixing sleeve 2, an adjusting component 4, and the adjusting component 4. The fixing sleeve 2 is rotatably mounted on the fixing base 1, and has a fixing cavity extending axially through it. The adjusting components 3 are arranged circumferentially around the outer periphery of the fixing sleeve 2 on the fixing base 1, and adjust the clamping diameter formed by the adjusting components 3 as the fixing sleeve 2 rotates. The adjusting component 4 is used to adjust the circumferential rotation of the fixing sleeve 2.

[0034] Specifically:

[0035] See Figures 1 to 2 As shown, the fixed base 1 has an axial through hole in the center. The fixed sleeve 2 can be installed in the axial through hole and rotated by means of a bearing connection. The base plate of the fixed base 1 is integrally formed with a folded plate, and the folded plate has a threaded hole for installation. Thus, the fixed base 1 can be fixed to the corresponding bracket by bolts. The fixed sleeve 2 has a fixed cavity through it along the axial direction. When in use, the fixed part of the striking tool is inserted into the fixed cavity. The clamping diameter can be changed by adjusting the diameter adjustment component 3, thereby clamping striking tools of different sizes.

[0036] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, the diameter adjustment assembly 3 includes an adjusting arm 301, a limiting sleeve 302, and a roller 303. One end of the adjusting arm 301 has a connecting hole 6. A stepped shaft 5 is fixedly mounted on the side of the fixed base 1 facing the diameter adjustment assembly 3. The stepped shaft 5 is installed in the connecting hole 6 via a bearing connection, allowing the adjusting arm 301 to rotate around the stepped shaft 5. The other end of the adjusting arm 301 passes through the limiting sleeve 302 and extends into the fixed cavity. A U-shaped wheel frame is provided at the end of the adjusting arm located in the fixed cavity, and the roller 303 is rotatably mounted on the U-shaped wheel frame via a wheel axle. Furthermore, a shaft 10 is integrally formed on the side of the limiting sleeve 302 facing the fixed base 1, and the shaft 10 is connected to the fixed sleeve 2 via a bearing connection.

[0037] In the above embodiment, the adjusting component 4 includes a first base 402, a second base 403, and an adjusting shaft 5 rod 401. The first base 402 is fixedly connected to the fixed base 1, and the second base 403 is connected to the fixed sleeve 2. An ear plate 7 is integrally formed on the outer wall of the fixed sleeve 2, and a shaft hole 8 is formed on the ear plate 7. A pin 9 is integrally formed on the second base 403, and the pin 9 is rotatably installed in the shaft hole 8 by means of a bearing connection. In the above embodiment, the first base 402 is provided with a smooth through hole, and the second base 403 is provided with a threaded through hole. Meanwhile, the adjusting shaft 5 rod 401 includes a smooth rod section and a lead screw section. The smooth rod section passes through the smooth through hole and forms a smooth connection with the first base 402. Baffles are integrally formed at both ends of the smooth rod section to limit the axial position of the first base 402 and the smooth rod section, ensuring that the smooth rod section can only rotate and cannot move back and forth. The lead screw section forms a threaded connection with the second base 403 through the threaded through hole.

[0038] Based on the above, it can be imagined that when it is necessary to adjust the size of the clamping opening formed by the adjusting component 3, the operation steps are as follows:

[0039] First, the user rotates the adjusting shaft 5 rod 401 by turning the handle at the end of the smooth rod section. The rotation of the adjusting shaft 5 rod 401 causes the second base 403 to move along the lead screw section. Since the second base 403 can rotate, the movement of the second base 403 causes the fixed sleeve 2 to rotate. The rotation of the fixed sleeve 2 causes the adjusting arm to extend and retract under the limit of the limiting sleeve 302. Thus, as the adjusting arm 301 extends and retracts, the clamping diameter is changed, achieving the purpose of clamping different sized striking instruments.

[0040] Of course, in a preferred embodiment, in order to ensure the stability of the adjusting assembly 3 during movement, an auxiliary collar is also provided on the outer side of the fixed sleeve 2. The adjusting arm 301 is located between the fixed sleeve 2 and the auxiliary collar, and the limiting sleeve 302 has a shaft 10 formed on the side facing the auxiliary collar. The shaft 10 is rotatably connected to the auxiliary collar through a bearing connection. It is easy to understand that installing the limiting sleeve 302 between the auxiliary collar and the fixed sleeve 2 enhances the connection stability of the limiting sleeve 302.

[0041] In summary, the adjustable diameter fixing structure for large animal striking devices provided in this application allows the adjusting component to change the size of the clamping opening formed by the adjusting component, thereby enabling the fixing sleeve to form clamping areas of different sizes, thus achieving the clamping of striking devices of different sizes and effectively improving the versatility of such striking devices.

[0042] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
