The fixing screw 5 is a hollow structure, and the fixing screw 5 is communicated with the tube body 1. The filter screen 305 forms a detachable structure with the filter head 301 through the mounting slot 303, the mounting block 304, and the outer dimensions of the mounting slot 303 and the mounting block 304 are adapted to each other. The filter screen 305 abuts against the bottom of the fixing screw 5, and the fixing screw 5 is fixedly connected to the tube body 1.

[0029] By adopting the above technical solution, the tube bodies 1 can be connected to the filter head 301 through the fixed screw 5, so that the tube bodies 1 can be spliced. At the same time, one end of the tube body 1 is connected to the pipeline through the hollow fixed screw 5, and the other end is connected to the pipeline through the filter head 301. When the hydraulic oil passes through the tube body 1, it will be filtered through the filter screen 305. If the filter screen 305 is blocked, the fixed screw 5 can be rotated to separate the fixed screw 5 from the filter head 301, and the filter screen 305 in the connecting hole 302 can be taken out. After cleaning, the installation block 304 on the filter screen 305 can be aligned with the installation slot 303 and re-inserted into the connecting hole 302, and the fixed screw 5 is rotated to screw into the interior of the filter head 301, and the bottom of the fixed screw 5 presses the filter screen 305 to prevent the filter screen 305 from shaking.

When the hydraulic oil passes through the tube body 1, it will be filtered through the filter screen 305. If the filter screen 305 is blocked, the fixing screw 5 can be rotated to separate the fixing screw 5 from the filter head 301, and the filter screen 305 in the connecting hole 302 can be taken out. After cleaning, the mounting block 304 on the filter screen 305 can be aligned with the mounting slot 303 and re-inserted into the connecting hole 302.
