[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a simple rubber ring cutting device, including a base 1, a support column 2 is fixedly connected to the top of the base 1, a travel rod 3 is fixedly connected to the front end of the support column 2, a sliding sleeve 4 is slidably connected to the surface of the travel rod 3, and a first rotating shaft 5 is fixedly connected to the outer surface of the sliding sleeve 4 on all sides, and a first connecting rod 6 is rotatably connected to the inside of the first rotating shaft 5, and an end of the first connecting rod 6 away from the first rotating shaft 5 is rotatably connected to the second rotating shaft 7, and a support plate 8 is fixedly connected to one side of the second rotating shaft 7. By sleeveing ​​the rubber ring to be cut on the surface of the support plate 8, the sliding sleeve 4 is moved so that the two ends of the first connecting rod 6 can be used in conjunction with the first rotating shaft 5 and the second rotating shaft 7 to open the support plate 8, so that the surface of the support plate 8 fits with the inner diameter of the rubber ring, and the rubber ring is supported and fixed, so as to facilitate cutting. The operation method is simple, and the overall structure is relatively simple, which is easy to repair when damaged.

[0023] Reference Figure 3 As shown, in the present embodiment: the front end of the travel rod 3 is fixedly connected with a round block 9, and travel grooves 10 are opened all around the round block 9. The inside of the travel groove 10 is slidably connected with a telescopic rod 11, and the end of the telescopic rod 11 away from the round block 9 is fixedly connected with a connecting seat 12, and the side of the connecting seat 12 close to the support plate 8 is fixedly connected to the support plate 8. When the support plate 8 is moved by the first connecting rod 6, the sliding connection between the telescopic rod 11 and the inner diameter of the travel groove 10 plays an auxiliary supporting role for the movement of the support plate 8, thereby preventing the support plate 8 from unilaterally tilting and affecting the support for the rubber ring.

[0024] Reference Figure 3As shown, in this embodiment: a through groove 13 is opened around the front end of the round block 9, and a limit rod 14 is slidably connected inside the through groove 13. The rear end of the limit rod 14 is fixedly connected to the telescopic rod 11. The sliding connection between the through groove 13 and the limit rod 14 limits the movement of the telescopic rod 11, thereby preventing the telescopic rod 11 from being separated from the inner diameter of the travel groove 10.

[0025] Reference Figure 4 and Figure 5 As shown, in this embodiment: the top of the sliding sleeve 4 is fixedly connected with a shell 15, both sides of the shell 15 are provided with through holes 16, the inner wall of the through hole 16 is slidably connected with a control rod 17, and the ends of the control rods 17 close to each other are fixedly connected with a first U-shaped block 18, the interior of the first U-shaped block 18 is rotatably connected with a second connecting rod 19 through a rotating shaft, the bottom of the second connecting rod 19 is rotatably connected with a second U-shaped block 20 through a rotating shaft, and the bottom of the second U-shaped block 20 is fixedly connected with an insertion rod 21, and the top of the travel rod 3 is provided with a slot 22 used in conjunction with the insertion rod 21, and the number of the slots 22 is several, and the bottom of the insertion rod 21 passes through the top of the sliding sleeve 4 and is slidably connected to the inner wall of the slot 22, and is moved to the bottom of the travel rod 3. The control rod 17 is moved away from the side of the shell 15, so that the first U-shaped block 18 drives the second connecting rod 19 to move, and the second connecting rod 19 drives the second U-shaped block 20 to move upward, so that the insertion rod 21 is disengaged from the inner diameter of the slot 22, and the limit on the sliding sleeve 4 is released, so that the user can move the sliding sleeve 4 according to the size of the rubber ring so that the support plate 8 can better support the rubber ring. When the sliding sleeve 4 moves to a suitable position, the control rod 17 is pressed to make the first U-shaped block 18 drive the second connecting rod 19 to move the second U-shaped block 20 downward, so that the insertion rod 21 is inserted into the slot 22, so as to limit the sliding sleeve 4 and prevent the sliding sleeve 4 from shifting when the rubber ring is cut.

[0026] Reference Figure 5 As shown, in this embodiment: the front end and the rear end of the second U-shaped block 20 are fixedly connected with the first slider 23, and the front end and the rear end inside the shell 15 are provided with a first slide groove 24 used in conjunction with the first slider 23. When the second U-shaped block 20 drives the insertion rod 21 to move up and down, the sliding connection between the first slider 23 and the first slide groove 24 assists the movement of the insertion rod 21 and prevents the second U-shaped block 20 from being offset.

[0027] Reference Figure 5 As shown, in this embodiment: the front end and the rear end of the first U-shaped block 18 are fixedly connected with the second slider 25, and the front end and the rear end of the inner cavity of the shell 15 are provided with a second slide groove 26 used in conjunction with the second slider 25. Through the sliding connection between the second slider 25 and the second slide groove 26, the movement of the first U-shaped block 18 is guided to prevent the first U-shaped block 18 from being offset when moving.

[0028] Reference Figure 5 As shown, in this embodiment: a limit spring 27 is sleeved on the surface of the control rod 17, and the end of the limit spring 27 close to the shell 15 is fixedly connected to the shell 15, and the end of the limit spring 27 away from the shell 15 is fixedly connected to the control rod 17. When the insertion rod 21 is inserted into the inner diameter of the slot 22, the position of the control rod 17 is limited by the tension generated by the limit spring 27 to prevent the control rod 17 from moving by itself due to external factors and causing the insertion rod 21 to be detached from the inside of the slot 22.

[0029] Working principle of the utility model: the user puts the rubber ring to be cut on the surface of the support plate 8, moves the sliding sleeve 4 so that the two ends of the first connecting rod 6 cooperate with the first rotating shaft 5 and the second rotating shaft 7 to open the support plate 8, so that the surface of the support plate 8 fits with the inner diameter of the rubber ring, and the rubber ring is supported and fixed for easy cutting. When cutting rubber rings of different specifications, the control rod 17 is moved to the side away from the shell 15, so that the first U-shaped block 18 drives the second connecting rod 19 to move, and the second connecting rod 19 drives the second U-shaped block 20 to move upward, so that the insertion rod 21 is disengaged from the inner diameter of the slot 22, and the limit of the sliding sleeve 4 is released, so that the user can move the sliding sleeve 4 according to the size of the rubber ring to make the support plate 8 To better support the rubber ring, when the sliding sleeve 4 moves to a suitable position, the control rod 17 is pressed to make the first U-shaped block 18 drive the second connecting rod 19 to move the second U-shaped block 20 downward, so that the insertion rod 21 is inserted into the slot 22, so as to limit the sliding sleeve 4 and prevent the sliding sleeve 4 from shifting when the rubber ring is cut. When the support plate 8 moves through the first connecting rod 6, the sliding connection between the telescopic rod 11 and the inner diameter of the travel groove 10 plays an auxiliary supporting role for the movement of the support plate 8, preventing the support plate 8 from unilaterally tilting and affecting the support for the rubber ring. The sliding connection between the through groove 13 and the limiting rod 14 plays a limiting role for the movement of the telescopic rod 11, preventing the telescopic rod 11 from being separated from the inner diameter of the travel groove 10.
