[0023] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0024] As shown in Figure 1 , 2 , the embodiment provides a maintenance tool for the valve locking piece of the internal combustion engine of the engineering machinery, which comprises a connecting part, a fixing part and an operating part;

[0025] The fixing part comprises a connecting block 1 and a fixing rod 2, one end of the connecting block is movably connected with one end of the connecting part, the other end of the connecting block is movably connected with the fixing rod, and the distal end of the fixing rod is provided with external threads 3; specifically, in the embodiment, as shown in Figure 1 , one end of the connecting block is movably connected with one end of the connecting part through a pin shaft, after the fixing rod is connected with the connecting block, the fixing rod can rotate relative to the connecting block, so that the fixing rod is connected with the internal combustion engine through the external threads, it can be considered that one end of the fixing rod is inserted into the connecting block without falling out, and there is a movable space between the fixing rod and the connecting block, so that the fixing rod can rotate relative to the connecting block, the external threads 3 at the distal end of the fixing rod can be connected with the threaded holes on the table surface of the internal combustion engine of the engineering machinery, a regular hexagonal operating surface 7 is further formed on the outer surface of the fixing rod, which facilitates the operation of the tool to fix the fixing rod, so that the fixing rod is connected with the threaded holes on the table surface of the internal combustion engine of the engineering machinery through the external threads 3, after the fixing rod is connected with the threaded holes on the table surface of the internal combustion engine of the engineering machinery through the external threads 3, the fixing rod plays a supporting role on the tool;

[0026] like Figure 1 As shown, the operating component 4 is sleeved on the connecting component. The connecting component includes a connecting rod 8, one end of which forms an operating handle 9. The surface of the operating handle has an anti-slip texture. Several toothed grooves 5 are provided on the connecting rod along its length direction. The operating component has a toothed key 6 that mates with the toothed grooves inside. The operating component can move freely along the length direction of the connecting component. The end of the operating component forms a claw shape for grasping the lock piece or a positioning groove for installing the lock piece. In this embodiment, the end of the operating component forms a hollow positioning groove 10 for installing the lock piece.

[0027] When installing the valve lock plate, first install the fixing rod on the engine table of the construction machinery to support the tool. Select a valve lock plate that matches the valve model from the spare parts. Check the lock plate for damage, deformation, or other defects. If there are any problems, it cannot be used. Align the hollow positioning groove 10 of the tool's installation lock plate with the valve lock plate, ensuring that the lock plate is accurately placed in the groove. Then, slowly bring the tool with the lock plate close to the top of the valve stem, ensuring that the tool and the valve stem are coaxial. Hold the operating handle and slowly and steadily apply downward pressure to push the lock plate along the valve stem to the slot position. When the lock plate is close to the slot, the pressure can be reduced appropriately to ensure that the lock plate is accurately installed. After installation, gently shake the tool to check whether the lock plate is securely installed.

[0028] When removing the valve lock plate, align the gripping claw of the special tool with the valve lock plate. You can adjust the position of the claw by gently rotating the tool to make it fully fit the lock plate. Hold the operating handle and apply upward force steadily to pull the lock plate out of the valve stem groove. During the pulling process, keep the tool perpendicular to the valve stem to prevent uneven force on the lock plate and damage. After disassembly, place the lock plate properly.

[0029] In this embodiment, the tool's operating handle is made of metal with a non-slip texture. Its shape is ergonomically designed for easy gripping and force application by maintenance personnel. The connecting rod is typically made of metal, such as stainless steel or high-strength alloy steel. The connecting rod has sufficient strength and rigidity to transmit the force of the operating handle, while its diameter and length are reasonably designed to ensure operability in the complex internal space of the engine. The operating component 4 is designed according to the specific shape and size of the valve lock plate. For different types of internal combustion engines, the working head has different design forms, such as claw shapes for gripping the lock plate or positioning grooves for installing the lock plate. Its material is generally high-hardness alloy steel, which undergoes fine machining and heat treatment to ensure its wear resistance and precision.

[0030] The tool in the embodiment can adapt to internal combustion engine of different models and structures and can be flexibly operated in narrow valve chamber space through reasonable connection component design.

[0031] The above embodiments are described in detail, but the content is only the preferred embodiment of the utility model, and cannot be considered as limiting the implementation range of the utility model. Any equivalent change and improvement made according to the application range of the utility model should still belong to the patent coverage range of the utility model.
