[0002] The ink fountain is a very common tool in traditional Chinese woodworking industry, and it has three main uses: 1. To draw long straight lines (it is also indispensable in the mud, stone, tile and other industries). The method is to fix one end of the ink line after soaking in ink, pull out the ink line and tighten it to the required position, then lift the middle section and flick it down; 2. The ink tank stores ink, and is used with an ink stick and a ruler to draw short straight lines or make marks; 3. To draw vertical lines (used as a plumb line), but the traditional ink fountain wheel is stored on the inside, which makes it difficult to brake the wheel when in use, so a brakeable variable speed ink fountain is needed.

[0003] The ink fountain commonly used at present has a brake structure added to the old ink fountain to facilitate braking of the wire wheel on the outside, but it still does not change the problem that the wire wheel rotates one circle when the old ink fountain is used, resulting in a slow wire-winding speed and low work efficiency. In addition, the wire wheel of the ordinary ink fountain is not convenient when loading the wire, and the wire wheel cannot be quickly disassembled and assembled, and the convenience of use is poor.

The first large gear 6, the first small gear 7, the second large gear 8 and the second small gear 9 are engaged with each other to achieve secondary deceleration, so that the wheel axle rotates multiple times when the turning handle 5 is turned one circle, so as to increase the wire taking-up speed. The sealed space formed by the second guard frame 2 and the shell plate 12 is used to seal the wire reel 10, so that the wire reel 10 is inside the plate and the wire is not stuck. When in use, the gears are engaged step by step by turning the turning handle 5, driving the wire reel 10 to rotate, and then driving the outer pull line 18 to be wound and recovered, so as to achieve rapid wire taking-up operation, greatly improving the wire taking-up speed and improving work efficiency.

[0030] Furthermore, a sleeve 13 is fixedly connected between the inner sides of the second guard frame 2, and the sleeve 13 is respectively located on the upper left side and the lower right side between the inner sides of the second guard frame 2. A through hole with a diameter smaller than the inner diameter of the sleeve 13 is opened on the rear side of the second guard frame 2. The sleeve 13 is used to seal and protect the quick-release assembly, and the through hole is used to limit the stepped shaft 14 to prevent it from detaching, thereby protecting the internal structure.

One end of the spring 15 is in conflict with a side surface of the stepped shaft 14 where the outer diameter is larger. By pressing one end of the stepped shaft 14 to make it slide in the sleeve 13 and compressing the spring 15 at the same time, the clamping plate 16 is disengaged from the strip groove, and then the pressure plate 17 can be rotated to release the limit on the shell plate 12, thereby facilitating the disassembly and installation of the reel 10. The operation is simple and easy to use.

[0032] Furthermore, the ink filling assembly includes a cover plate rotatably connected to the top of the first protective frame 1, a pressure rod is slidably connected inside the cover plate, a spring is provided on the outer sleeve of the pressure rod, and a leaf-shaped plate is fixedly connected to one end of the pressure rod. This partial structure can facilitate the opening and closing of the position of the ink absorbing pad, thereby facilitating the ink filling operation.

[0033] Furthermore, a pull wire 18 is slidably connected inside the wire mouth 4, and the pull wire 18 is wound around the outside of the wire wheel 10. The pull wire 18 can be retracted by rotating the wire wheel 10. When in use, it can be pulled out through the wire mouth 4, which is convenient for use.

[0034] Furthermore, an ink-absorbing pad is fixedly connected to the first protective frame 1. The ink-absorbing pad is made of sponge and is used to absorb ink to dye the pull wire 18. A channel is opened in the ink-absorbing pad to facilitate the passage of the pull wire 18 to avoid interference.

[0035] Furthermore, strip grooves are respectively provided on the left and right sides of the front side of the second guard frame 2, and the cross-section of the strip grooves is adapted to the outer contour of the clamping plate 16. The strip grooves cooperate with the clamping plate 16 to fix the position of the pressure plate 17, making it difficult to rotate when fixed, so as to ensure its reliability in fixing the shell plate 12.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
