[0051] The bracket unit includes a connecting plate 201 and a patterned handle 202;

[0052] Two patterned handles 202 are provided, and the two patterned handles 202 are symmetrically fixed at both ends of the connecting plate 201 to provide a handhold for the connecting plate 201;

[0053] The bottom of the connecting plate 201 is provided with multiple convex holes and slots for installing the upper guide sleeve 102 and the lower guide sleeve 109, and the multiple convex holes and slots are distributed sequentially along the horizontal direction.

[0054] The positioning unit includes a guide seat 203, a straight rod 204, an anti-slip cap 205, and a positioning post 206;

[0055] Two guide seats 203 are provided. The two guide seats 203 are symmetrically fixedly installed at the top two ends of the connecting plate 201. The straight rod 204 is vertically slidably connected to the inside of the guide seat 203 and passes through the guide seat 203 and the upper and lower ends of the connecting plate 201. The anti-detachment cap 205 is symmetrically positioned at the upper and lower ends of the straight rod 204 and is used to limit the vertical movement height of the straight rod 204.

[0056] The positioning pin 206 is fixed to the bottom of the lower anti-detachment cap 205. The positioning pin 206 is inserted into the corresponding pin hole of the cylinder body to achieve automatic alignment of the piston nozzle 3 with the piston nozzle installation position on the cylinder body.

[0057] In this embodiment, the operation steps for installing the engine piston nozzle 3 are as follows;

[0058] First, the fixing bolt of the piston nozzle 3 can be passed through the mounting hole on the mounting plate, and then the whole thing can be installed into the bottom of the lower guide sleeve 109. The mounting plate 302 is snapped into the positioning groove 111, the nozzle body 301 protrudes from the top of the mounting plate 302 and is stored in the storage hole groove 112, the guide tube 303 is snapped into the clearance opening groove 113, and the bottom end of the bit 108 is inserted into the groove of the fixing bolt. The strong magnet 114 at the bottom of the lower guide sleeve 109 attracts and fixes the mounting plate 302. In this way, when the whole device is facing down and the piston nozzle 3 is pushed to the installation position, the piston nozzle 3 can remain in a non-detached state.

[0059] After the piston nozzle 3 and the lower guide sleeve 109 are installed, the entire device can be facing downwards. Hold the patterned handle 202 and push the piston nozzle 3 to the installation position, and insert the positioning pin 206 into the corresponding pin hole of the cylinder body, so that the piston nozzle 3 is positioned and fixed, thus achieving the effect of locking the installation angle of the piston nozzle 3.

[0060] Then, by using an external tool (e.g., an electric wrench or a manual handle) to attach the polygonal head 103 and rotate it, the polygonal head 103, extension rod 106, and bit 108 can be rotated as a whole. The bit 108 drives the fixing bolt to tighten. During this process, a downward pushing force is simultaneously applied to the polygonal head 103, causing the polygonal head 103, extension rod 106, and bit 108 to push the fixing bolt towards the installation position, thus completing the installation and fixing of the piston nozzle 3.

[0061] It should be noted that: the limiting retaining ring 105 moves down synchronously with the extension rod 106, and the limiting retaining ring 105 compresses the spring 104 to contract. When the piston nozzle 3 is completed and the compression on the polygonal head 103 is released, the polygonal head 103, the extension rod 106, and the bit 108 can be reset to their initial positions under the action of the spring 104.

[0062] Please refer to this carefully. Figures 2-5 The lower guide sleeve 109 has a hollow structure inside, and the hollow structure is connected to the positioning groove 111. The fixing ring 110, the strong magnet 114, and the hollow structure are staggered and distributed. The bottom of the hollow structure of the lower guide sleeve 109 has a boss structure 115, and the inner diameter of the boss structure 115 decreases from top to bottom, which is used to limit the falling position of the bit 108.

[0063] In this embodiment, the boss structure 115 limits the falling position of the bit 108 to prevent the bit 108 from causing excessive pressure on the fixing bolt and piston nozzle 3.

[0064] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
