[0026] Please refer to Figures 1 to 4 As shown, a chain nozzle fixture includes a cylindrical handle 1. A semi-circular positioning post 2 is coaxially mounted on the bottom end of the handle 1. The semi-circular positioning post 2 has a nozzle positioning groove 3 on its plane. The bottom end of the nozzle positioning groove 3 passes through the end face of the semi-circular positioning post 2. A semi-circular sealing post 4 is also slidably mounted on the bottom end of the handle 1. The plane of the semi-circular sealing post 4 is slidably fitted with the plane of the semi-circular positioning post 2. A moving mechanism is constructed inside the handle 1. The moving end of the moving mechanism is connected to the top surface of the semi-circular sealing post 4. The moving mechanism is used to control the semi-circular sealing post 4 to move linearly along the axis of the handle 1. An auxiliary adjusting block 5 is installed on the side of the semi-circular positioning post 2 opposite to its plane. The auxiliary adjusting block 5 has a vertically penetrating auxiliary hole 6. The axis of the auxiliary hole 6 is parallel to the axis of the handle 1.

[0027] Thus, when installing the chain nozzle, the semi-circular sealing post 4 is moved upwards to expose the nozzle positioning groove 3. The chain nozzle is then placed into the nozzle positioning groove 3. After complete installation, the semi-circular sealing post 4 is pushed back, sealing the nozzle positioning groove 3. The chain nozzle to be installed is then fixedly assembled within the nozzle positioning groove 3, with the assembly and positioning portion of the chain nozzle exposed, its exposed length matching the assembly depth. Then, the handle 1 is held to insert the exposed portion of the chain nozzle into the corresponding mounting hole on the machine body. Since the auxiliary hole 6 and the oil spray end of the chain nozzle assembled in the nozzle positioning groove 3 have a fixed angle, the angle of the chain nozzle can be adjusted by rotating the handle 1 during assembly. A mark can be made on the machine body; aligning the auxiliary hole 6 with the corresponding mark indicates that the chain nozzle angle adjustment is complete. Finally, the top of the handle 1 is struck forcefully to bring the bottom end of the semi-circular positioning post 2 into contact with the machine body surface, completing the chain nozzle assembly. During the striking process, a vertical guide rod can be inserted into the auxiliary hole 6, and the bottom end of the guide rod can be positioned with the machine body to prevent the handle 1 from rotating during the striking process. After the chain nozzle is assembled, the semi-circular sealing block is pushed upward to open the nozzle positioning groove 3, thus separating the entire tooling from the chain nozzle.

[0028] Furthermore, the nozzle positioning groove 3 is used to position the liquid spraying section of the chain nozzle, and the axis of the nozzle positioning groove 3 located at the communication port on the end face of the semi-circular positioning post 2 is parallel to the axis of the handle 1.

[0029] Furthermore, the side wall of the nozzle positioning groove 3 for positioning the liquid spraying end of the chain nozzle is constructed with a relief groove 7, the side wall of the relief groove 7 is connected to the nozzle positioning groove 3, and the relief groove 7 is horizontally extended.

[0030] In this way, by using the clearance groove 7, when disassembling the chain nozzle, a thin rod can be inserted into the clearance groove 7 and pried to separate the chain nozzle from the nozzle positioning groove 3.

[0031] Furthermore, in order to allow the chain nozzle to be better and more stably assembled in the nozzle positioning groove 3, the depth of the nozzle positioning groove 3 is the same as the outer diameter of the cross-section of the chain nozzle.

[0032] Furthermore, to facilitate the movement of the semi-circular sealing post 4, the handle 1 is constructed with a displacement groove 8 for accommodating the moving mechanism. The moving mechanism includes a slide rod 9 slidably disposed in the displacement groove 8. A connecting rod 10 is coaxially mounted at the bottom end of the slide rod 9. The connecting rod 10 extends downward from the displacement groove 8 and connects to the top surface of the semi-circular sealing post 4. The inner diameter of the displacement groove 8 is larger than the outer diameter of the connecting rod 10.

[0033] In this way, by utilizing the fact that the inner diameter of the displacement groove 8 is larger than the outer diameter of the connecting rod 10, and the outer side wall of the connecting rod 10 slides against the bottom end of the grip, a limiting part can be formed at the bottom end of the displacement groove 8 to prevent excessive movement of the slide rod 9.

[0034] Furthermore, the side wall of the handle 1 is provided with a movable through groove 11, which is connected to the displacement groove 8. The side wall of the slide bar 9 is equipped with a grip bar 12, which is horizontally arranged and slidably disposed within the movable through groove 11.

[0035] In this way, the movement of the semi-circular sealing column 4 is adjusted by pulling the handle 12, while the bottom end of the moving through groove 11 is used to limit the sliding rod 9.

[0036] Furthermore, a compression spring 13 is installed inside the displacement groove 8, and the two ends of the compression spring 13 abut against the top end of the displacement groove 8 and the top end of the slide rod 9, respectively.

[0037] By setting the compression spring 13, the semi-circular sealing column 4 can always stably seal the nozzle positioning groove 3 during the chain spraying assembly process.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
