Description

Technical Field

[0001] This utility model relates to the field of mechanical support technology, specifically an improved cross-shaped adjustment seat. Background Technology

[0002] The cross adjustment base achieves free rotation and fine-tuning of its position within a plane through a bracket, adjustment rod, and sliding groove structure. It is used to mount cutting tools, which are integrated into the saw blade adjustment structure of the electric saw. The saw blade position is controlled by bidirectional adjustment functions (such as linear guides), improving cutting stability and accuracy. It can also be used as a core component of building decoration tools, serving as a tile leveling device for adjusting grout lines, positioning the base, and fixing clips during tile laying to ensure tile surface flatness. When used with a cross scale, it supports freely adjustable marking angles, assisting in wall or floor construction. Similar structures can also be used for adjustable mounting brackets (such as shower heads, bicycle racks, etc.), achieving multi-angle fixing and position adaptation through sliding grooves or screw structures.

[0003] Current adjustable cross-shaped supports offer stable support, but their fixed design makes them inconvenient to carry. This design is foldable, making it easy to carry. Utility Model Content

[0016] The top column 8 includes a limiting column 81, a spring 82, a positioning block 83, and a rotating column 84. The rotating column 84 is connected to the front and rear sides of the rotating frame 7. There are two positioning blocks 83, one of which is fixedly connected to one side of the rotating column 84. The limiting column 81 is fixedly connected between the two positioning blocks 83. The spring 82 is located on the annular side of the limiting column 81. One end of the spring 82 is fixedly connected to the top of the positioning block 83, and the other end of the spring 82 is fixedly connected to the bottom end of the horizontal side of the opening slot of the movable frame. The rotating frame 7 is rotatably connected between the two rotating columns 84, and the rotating columns 84 are located on the front and rear sides of the upper side of the bottom end of the rotating frame 7.

[0017] The rotating foot 5 includes a rotating shaft 51 and a supporting foot 52. The rotating shaft 51 is fixedly connected to the outer side of the side plate 2, and the supporting foot 52 is rotatably connected to the rotating end of the rotating shaft 51. The bottom end of the supporting foot 52 is fixedly connected with, but is not limited to, four rubber buffer pads.

[0018] The lead screw structure 4 includes a handle 41 and a lead screw 42. The lead screw 42 is located on the inner side of the ring below the movable frame 6.

To unfold the rotating frame 7, repeat the above operation in the opposite direction.

[0022] Working principle: The lead screw structure 4 controls the displacement of the moving frame 6, thereby adjusting the position of the rotating frame. The rotating feet are foldable, and the support feet are unfolded via the pivot, forming a cross with the bottom shell for support. When storage is required, the support feet move along the pivot towards the bottom shell. When the rotating frame 7 needs to be moved, the handle 41 can be turned by hand to rotate the lead screw 42, thereby moving the moving frame 6 and then the rotating frame 7. When folding the rotating frame, the frame is moved to the handle before folding. The space above the lead screw can be used for cutting tools. For storage, the handle can be limited by pushing the pin 412 within the slide groove 411 to the slot 413 side. If the rotating handle is needed, repeat the above operation in reverse. When the rotating frame 7 needs to be folded, manually press the bottom of the top post 8, that is, press the positioning block 83 upward by hand, so that the spring 82 is compressed. At this time, the limiting post 81 moves upward, and the positioning block 83 inside the rotating frame moves upward. The rotating frame 7 rotates 90 degrees counterclockwise along the center of the rotating post 84, thus folding the rotating frame 7 for easy storage and carrying. To unfold the rotating frame 7, repeat the above operation in reverse.
