DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] As shown in Figs. 1 to 4 The utility model provides a capillary fitting, including:

[0024] Shell 1, the inside fixed mounting of shell 1 has sliding rail 2;

[0025] Cutting mechanism, cutting mechanism is arranged in the inside of shell 1;

[0026] The cutting mechanism comprises a rotating shaft 3, the front and rear ends of the outer surface of the rotating shaft 3 are movably sleeved with the inside of the shell 1, the outer surface of the rotating shaft 3 is fixedly sleeved with a rotating wheel 4, the middle part of the outer surface of the rotating shaft 3 is fixedly connected with a steel wire rope 5, the other end of the steel wire rope 5 is fixedly connected with a sliding block 6, the left side of the sliding block 6 is fixedly installed with a spring 7, the left end of the spring 7 is fixedly installed with a pushing block 8, the left side of the pushing block 8 is movably connected with a movable block 9, the outer surfaces of the sliding block 6, the pushing block 8 and the movable block 9 are slidably connected with the inside of the sliding rail 2, the top end of the movable block 9 is fixedly installed with a fixed block 10, the inside of the fixed block 10 is movably sleeved with a blade 11, the outer surface of the blade 11 is movably connected with a capillary tube 12, and the outer surface of the capillary tube 12 is in contact with the outer surfaces of the shell 1 and the rotating wheel 4.

[0027] Due to the design of the sliding rail 2, the movement of the sliding block 6, the pushing block 8 and the movable block 9 is limited, so that they can only move left and right. When the operator places the capillary tube 12 between the rotating wheel 4 and the blade 11, the capillary tube 12 will push and extrude the blade 11 at this time. At this time, the blade 11 will drive the movable block 9 to move right through the fixed block 10. Then the movable block 9 will compress the spring 7 through the pushing block 8. Due to the design of the spring 7, the outer surface of the blade 11 can abut against capillary tubes 12 of different sizes. When the shell 1 rotates as a whole, the blade 11 will cut the capillary tube 12 at this time. At the same time, the rotating wheel 4 will drive the rotating shaft 3 to rotate. At this time, the rotating shaft 3 will wind the steel wire rope 5, so that the steel wire rope 5 pulls the sliding block 6. At this time, the sliding block 6 will move left and compress the spring 7 again. At this time, the spring 7 will increase the cutting force of the blade 11 on the capillary tube 12. With the increase of the number of revolutions of the shell 1 as a whole, the number of revolutions of the rotating shaft 3 on the steel wire rope 5 is also increased, so that the cutting force of the blade 11 on the capillary tube 12 is continuously increased. Until the capillary tube 12 is cut, the effect of cutting capillary tubes 12 of different sizes flexibly and conveniently is achieved.

[0028] The inside of the shell 1 is fixedly installed with a fixed shaft 13, the outer surface of the fixed shaft 13 is movably sleeved with a guide wheel 14, and the outer surface of the guide wheel 14 is in contact with the outer surface of the steel wire rope 5.

[0029] Due to the movably sleeving of the outer surfaces of the guide wheel 14 and the fixed shaft 13, the guide wheel 14 can rotate along the outer surface of the fixed shaft 13. Due to the design of the guide wheel 14, the steel wire rope 5 is well guided.

[0030] The outer ring of the rotating wheel 4 is made of rubber.

[0031] Due to the fact that the outer ring of the rotating wheel 4 is made of rubber, the rotating wheel 4 and the capillary tube 12 have a large friction force, so that when the rotating wheel 4 revolves around the capillary tube 12, the rotating shaft 3 can be driven to rotate.

[0032] The outer surface of the shell 1 is fixedly sleeved with a handle 16, the handle 16 is made of plastic, and the outer surface of the handle 16 is coated with a silica gel coating.

[0033] Due to the design of the handle 16, the operator can rotate the shell 1 as a whole through the handle 16, and due to the silica gel coating on the outer surface of the handle 16, the anti-slip and anti-static properties of the handle 16 are improved.

[0034] The inner surface of the bottom end of the fixed block 10 is slidably connected with a moving block 17, the top end of the moving block 17 is fixedly installed with a movable plate 18, and the inner surface of the movable plate 18 is movably sleeved with the outer surface of the blade 11.

[0035] Due to the sliding connection between the moving block 17 and the inner surface of the fixed block 10, the movable plate 18 can only drive the moving block 17 to move forward and backward along the inner surface of the fixed block 10, and due to the design of the movable plate 18, the fixed block 10 can be fixed with the movable plate 18 to fix the blade 11, when the movable plate 18 drives the moving block 17 to separate from the inner surface of the fixed block 10, the movable plate 18 will release the fixing of the blade 11, and the operator can replace the blade 11.

[0036] The top end of the movable plate 18 and the fixed block 10 is fixedly installed with a connecting block 19, the number of the connecting block 19 is two, and the inner surface of the connecting block 19 is threadedly sleeved with a bolt 20.

[0037] Due to the design of the bolt 20, the two connecting blocks 19 can be connected, and the connection between the fixed block 10 and the movable plate 18 can be fixed.

[0038] The working principle and use process of the utility model:

[0039] When the operator needs to cut the capillary tube 12, first the operator places the capillary tube 12 between the rotating wheel 4 and the blade 11, at this time the capillary tube 12 will push the blade 11 to move the fixed block 10 as a whole, at this time the fixed block 10 will drive the movable block 9 to move right along the inside of the slide rail 2, at this time the movable block 9 will compress the spring 7 by pushing the block 8, because the spring 7 has good elastic force, it can clamp the capillary tube 12 of different sizes, then the operator holds the handle 16 to drive the whole shell 1 to rotate around the capillary tube 12 as the axis, at this time the blade 11 will revolve around the outer surface of the capillary tube 12 under the driving of the whole shell 1, because of the design of the blade 11, when the blade 11 revolves around the capillary tube 12, it will scratch the outer surface of the capillary tube 12, at the same time the rotating wheel 4 will revolve around the outer surface of the capillary tube 12 under the driving of the whole shell 1, because the outer circle of the rotating wheel 4 is made of rubber, so the outer surface of the rotating wheel 4 has great friction with the outer surface of the capillary tube 12, therefore when the rotating wheel 4 revolves around the outer surface of the capillary tube 12, it will drive the shaft 3 to rotate around the joint between the movable sleeve of the shell 1 and the shaft 3, at this time the shaft 3 will wind the steel wire rope 5 in the rotation, in this process the other end of the steel wire rope 5 will pull the slide block 6 to move left along the inside of the slide rail 2, at this time the slide block 6 will compress the spring 7 again in the left movement, at this time the spring 7 will increase the pushing force of the pushing block 8, so as to increase the scratching force of the blade 11 on the capillary tube 12, with the increase of the number of rotations of the whole shell 1 driven by the operator, the number of windings of the shaft 3 on the steel wire rope 5 will also increase synchronously, so as to continuously increase the scratching force of the blade 11 on the capillary tube 12, so as to make the circumferential scratch on the capillary tube 12 deeper and deeper, finally the capillary tube 12 is cut, so as to realize the function of flexible and convenient cutting of capillary tubes 12 of different sizes.

[0040] When the blade 11 is damaged, the operator holds the screwdriver to screw the bolt 20 out from the inside of the two connecting blocks 19, at this time the bolt 20 will release the connection of the two connecting blocks 19, then the operator pulls the movable plate 18, at this time the movable plate 18 will drive the connecting block 19 and the moving block 17 to move, because the outer surface of the moving block 17 is in sliding connection with the inside of the fixed block 10, at this time the movable plate 18 will drive the moving block 17 to move forward along the inside of the fixed block 10, when the moving block 17 is separated from the inside of the fixed block 10, at this time the movable plate 18 will completely release the connection with the fixed block 10, so that the movable plate 18 and the fixed block 10 release the fixation of the blade 11, at this time the operator can take out the damaged blade 11 from the inside of the fixed block 10, when the operator inserts the new blade 11 into the inside of the fixed block 10, at this time the operator reinserts the moving block 17 into the inside of the fixed block 10, at this time the inside of the movable plate 18 is sleeved on the outer surface of the blade 11, when the two connecting blocks 19 are in close contact, at this time the movable plate 18 and the fixed block 10 complete the fixation of the blade 11, then the operator screws the bolt 20 into the design of the two connecting blocks 19, at this time the bolt 20 will fix and connect the movable plate 18 and the fixed block 10 through the two connecting blocks 19, so as to realize the function of facilitating the replacement of the blade 11.
