[0033] Reference Figure 1 and Figure 2 The adjusting assembly 6 includes a movable column 61, and the bottom inner wall of the movable column 61 is rotatably connected to a rotating shaft 62. The rotating effect of the rotating shaft 62 enables the cutting knife 5 to rotate. The top rear end of the cutting knife 5 is fixedly connected to a fixed column 67. The fixing effect of the fixed column 67 prevents the fixed column 67 from turning over and falling off. The moving effect of the fixed column 67 drives the cutting knife 5 to rotate. The outer periphery of the fixed column 67 is rotatably connected to a connecting rod 63. The moving effect of the connecting rod 63 drives the fixed column 67 to move. The inner wall of the left end of the connecting rod 63 is rotatably connected to a cylindrical rod 64. The moving effect of the cylindrical rod 64 drives the connecting rod 63 to move.

[0034] Reference Figure 3 and Figure 4 The clamping assembly 7 includes a fixed plate 71, and there are two groups of fixed plates 71 and movable plates 72 symmetrically distributed. The clamping surfaces of the two groups of fixed plates 71 and movable plates 72 are made of rubber material and have a certain elasticity. A slide groove 78 is provided on the top of the workbench 1. There are two groups of slide grooves 78 symmetrically distributed. The inner wall of the slide groove 78 is slidably connected with the movable plate 72. Through the sliding effect of the movable plate 72, the movable plate 72 and the fixed plate 71 can clamp and fix the straw, or release the fixing effect. The front side of the movable plate 72 is fixedly connected with a push-pull rod 73, and the left and right ends of the push-pull rod 73 are respectively fixed to the front sides of the two groups of movable plates 72.

[0035] Reference Figure 2The outer periphery of the threaded rod 4 is rotatably connected to the inner wall of the support frame 2, and the inner wall of the top rear end of the movable column 61 is threadedly connected to the outer periphery of the threaded rod 4. The rotation effect of the threaded rod 4 drives the movable column 61 to slide vertically. The outer wall of the movable column 61 is slidably connected to the inner wall of the support frame 2. The sliding effect of the movable column 61 drives the cutting knife 5 to move vertically to cut the straw.

[0036] Reference Figure 2 The bottom of the rotating shaft 62 is fixedly connected to the top of the cutting knife 5, and the cutting knife 5 is prevented from falling off by the fixing effect of the cutting knife 5. The left side of the movable column 61 is fixedly connected with an electric telescopic rod 66. By starting the electric telescopic rod 66, the connecting block 65 is driven to move laterally. The output end of the electric telescopic rod 66 is fixedly connected with the connecting block 65. Through the lateral movement effect of the connecting block 65, the cylindrical rod 64 is driven to move laterally. The bottom of the connecting block 65 is fixedly connected to the top of the cylindrical rod 64. Through the fixing effect of the connecting block 65, the connecting block 65 is prevented from falling off.

[0037] Reference Figure 3 and Figure 4 The bottom end of the fixed plate 71 is fixedly connected to the inner wall of the slide groove 78. The fixing effect of the fixed plate 71 prevents the fixed plate 71 from falling off. The outer wall of the push-pull rod 73 penetrates and is slidably connected to the front inner wall of the workbench 1. By pushing or pulling the push-pull rod 73, the two groups of movable plates 72 can be driven to slide at the same time. A sliding rod 74 is fixedly connected to the back of the push-pull rod 73. By limiting the sliding rod 74, the push-pull rod 73 is kept fixed, thereby keeping the two groups of movable plates 72 fixed.

[0038] Reference Figure 3 The top inner wall of the workbench 1 is elastically connected to a block 76 by a spring 75. The elastic force of the spring 75 ensures that the block 76 always maintains a clamping effect with the slot when not subjected to external force, thereby limiting the sliding rod 74. A pull rod 77 is fixedly connected to the top of the block 76. A clamping slot is provided on the right side of the sliding rod 74. There are multiple groups of clamping slots. The multiple groups of clamping slots are used to clamp the block 76 at different positions, thereby limiting the sliding rod 74 at different positions. The outer periphery of the sliding rod 74 is slidably connected to the front inner wall of the workbench 1. One end of the spring 75 is fixedly connected to the top inner wall of the workbench 1, and the other end of the spring 75 is fixedly connected to the right side of the block 76. The fixing effect of the spring 75 keeps the block 76 fixed to prevent the block 76 from falling off.

[0039] Reference Figure 3The outer wall of the block 76 is slidably connected to the inner wall of the top of the workbench 1. Through the sliding effect of the block 76, the block 76 and the slot are engaged or released. The outer wall of the block 76 is engaged with the inner wall of the slot. Through the engagement effect of the block 76 and the slot, the workbench 1 limits the sliding rod 74. The outer wall of the pull rod 77 is slidably connected to the inner wall of the top of the workbench 1. Through the sliding effect of the pull rod 77, the block 76 is driven to slide.

[0040] Working principle: when the staff needs to cut the plastic straws, the staff places the straws on the workbench 1, and makes the two ends of the plastic straws respectively in the middle position of the two groups of fixed plates 71 and the two groups of movable plates 72, and the staff pulls the pull rod 77 to the right, so that the block 76 releases the clamping effect with the clamping slot, and at the same time releases the limiting effect on the sliding rod 74, and then pushes the push-pull rod 73, so that the push-pull rod 73 simultaneously drives the two groups of movable plates 72 to slide along the inner wall of the slide slot 78 toward the back side of the workbench 1, so that the two groups of movable plates 72 and the two groups of fixed plates 71 clamp and fix the two ends of the plastic straws respectively. After clamping, release the pull rod 77, so that the block 76 is clamped with the clamping slot under the elastic force of the spring 75, and at the same time limits the sliding rod 74, so that the two groups of movable plates 72 remain fixed.

[0041] The staff starts the motor 3, and the motor 3 drives the threaded rod 4 to rotate, so that the movable column 61 drives the rotating shaft 62 and the cutting knife 5 to move downward, and the cutting knife 5 cuts the straw. When it is necessary to cut the straw at an angle, the staff starts the electric telescopic rod 66, and the electric telescopic rod 66 drives the connecting block 65 to move left, so that the connecting block 65 drives the cylindrical rod 64 to move left, so that the connecting rod 63 drives the fixed column 67 to move, thereby driving the cutting knife 5 and the rotating shaft 62 to rotate counterclockwise to adjust the cutting angle of the cutting knife 5. When it is necessary to reset the cutting knife 5, the electric telescopic rod 66 is controlled to retract, thereby driving the cutting knife 5 to rotate clockwise for resetting.

[0042] When the cutting of the plastic straws is completed, the staff pushes the pull rod 77 to the right to release the limit on the sliding rod 74, and pulls the push-pull rod 73 outward, thereby driving the two sets of movable plates 72 to slide toward the front direction of the workbench 1, releasing the clamping and fixing effect on the plastic straws, making it easier for the staff to remove the straws.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
