Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a tobacco plant puller of the present invention comprises an upper clamping jaw 3, a lower clamping jaw 2 and a gripping rod 1, wherein the gripping rod 1 is fixedly connected to the lower clamping jaw 2, and a rotating support rod 8 is movably installed on one side of the lower clamping jaw 2 through a rotating shaft, one end of the rotating support rod 8 is fixedly connected to the upper clamping jaw 3, and the other end is provided with a cylinder 9, a positioning opening 19 is provided on the upper clamping jaw 3, a push plate 14 is provided in the positioning opening 19, a plurality of insertion rods 4 are installed on one side surface of the push plate 14, and the other ends of the insertion rods 4 are all arranged to the outside world through the positioning opening 19, an arc plate 5 connected to the push plate 14 is installed on the side surface of the upper clamping jaw 3 away from the insertion rod 4, and a cloth 6 for pressing the arc plate 5 onto the lower clamping jaw 2 is provided on the outside, one end of the cloth 6 is installed on the lower clamping jaw 2, and a pull rod 7 is installed on the other end, and a connecting component is installed on one side of the pull rod 7.

[0021] In this embodiment, the connecting assembly includes a wire rope 10, a pressure rod 13, a first compression spring 12 and a positioning block 11. The positioning block 11 is installed on the grip rod 1. The positioning block 11 is provided with an axial hole. One end of the wire rope 10 is installed on the pull rod 7, and the other end passes through the axial hole and is fixedly connected to the pressure rod 13. The first compression spring 12 is sleeved on the outside of the wire rope 10. One end of the first compression spring 12 is installed on the positioning block 11, and the other end is installed on the pressure rod 13. The elastic energy of the first compression spring pushes the pressure rod, the wire rope and the pull rod upward, and the upward thrust on the pull rod can act on the fabric, so that the fabric is in a taut state, thereby pressing the arc plate onto the lower clamp.

[0022] In this embodiment, a slide groove 18 is vertically provided on one side surface of the lower clamping jaw 2, and a slider 17 is installed at one end of the pull rod 7. The slider 17 is slidably set in the slide groove 18. The cross-sections of the slider 17 and the slide groove 18 are both trapezoidal structures. The pull rod can be positioned through the slide groove and the slider so that the pull rod can only move up and down along the slide groove.

[0023] In this embodiment, the lower clamping jaw 2 is provided with positioning holes 20 on both sides of the push plate 14, and the inner side surface of the arc plate 5 is installed opposite to the positioning holes 20. The other end of the positioning rod 15 is inserted into the positioning hole 20 and is installed with a second compression spring 16. The other end of the second compression spring 16 is installed on the inner wall surface of the positioning hole 20. When the arc plate is in contact with the lower clamping jaw, the second compression spring is in a compressed state. Therefore, after the fabric loses pressure on the arc plate, the arc plate and the push plate can be automatically pushed outward by the rebound of the second compression spring.

[0024] In this embodiment, the positioning opening 19 and the push plate 14 are both tilted, and one end of the insertion rod 4 is tilted upward, so that the insertion rod 4 can be inserted into the cigarette rod more smoothly.

[0025] In this embodiment, the fabric 6 is made of ultra-high molecular weight polyethylene fiber fabric, which has the characteristics of high strength, high modulus, wear resistance, and cut resistance, thereby increasing the service life.

[0026] When in use, hold the grip rod and put the lower clamping jaw and the upper clamping jaw on the root of the cigarette rod. After rotating the grip rod around the rotating support rod, the lower clamping jaw can move closer to the upper clamping jaw and clamp the cigarette rod. During the process of moving closer, the insertion rod can be inserted into the cigarette rod, thereby avoiding slipping between the lower clamping jaw and the cigarette rod or displacement of the cigarette rod during the subsequent withdrawal process. In the process of insertion, it is best to hold the pressure rod to keep the push plate in a stable state to avoid backward movement.

[0027] After the above is completed, continue to press the grip rod downward and make the cylinder body contact with the ground. Through the support between the cylinder body and the ground, a force point can be applied to the grip rod, so that the grip rod can directly lift the upper clamping jaw and the lower clamping jaw upward through the lever principle, and simultaneously bring the cigarette rod out. After the cigarette rod is pulled out, the pressure rod can be pressed down. After the pressure rod drops, the wire rope will be in a relaxed state, so the rebound of the second compression spring can push the positioning stem and the arc plate outward, and the arc plate can smoothly push the fabric outward. The movement of the arc plate synchronously drives the push plate and the insertion rod, so that the insertion rod can be directly pulled out of the cigarette rod, which is convenient for separation from the cigarette rod.

[0028] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
