[0001] The present application relates to the field of branch tying machines, and more particularly to a branch tying machine. Background Art

[0002] A wire binder is an agricultural tool used to bind branches and vines of crops, fruit trees, flowers, etc. The existing wire binder usually includes a binder body, a handle, a clamping piece with a wire feeding port, a wire binding box and a spiral bender.

[0003] At present, the World Intellectual Property Organization with a publication number of WO2019155163A1 has disclosed a patent for a clamp-type plant bundling device (P), comprising at least two articulated arms and a supply subassembly in a fastened connection. The user's actuation on the clamp (P) causes the opening and closing of the articulated arm, and the front end of the articulated arm is equipped to undertake the following operations: providing a certain length of fastening link, forming a ring, cutting the fastening link, and closing the ring for bundling purposes. The device includes the first arm in one articulated arm, a retaining subassembly at the first end of the fixed link, and the retaining subassembly is used to provide a fastening link for forming a loop. The length of the loop, the first end of the fastening link to be held is carried by the other arm of the second arm, the holding subassembly is formed by a fixed jaw and a movable jaw, the fixed jaw and the movable jaw slide in the first arm to move from the clamped position of the first end of the fastening link carried by the second arm during the operation of providing a certain length of fastening link and forming the loop, the rotational movement of the arm actuates a cam follower and is pre-formed with a cam path, a finger or roller is associated with the movable jaw by means of the cam path so as to synchronize the rotational movement of the articulated arm with the translational movement of the movable jaw.

[0004] In the prior art, similar to the above-mentioned clamp-type plant bundling device (P), the cam follower used is pre-formed with a cam path, and the finger or roller is associated with the movable jaw through the cam path. During long-term use, it is easy to get stuck and the movement is discontinuous, which makes the clamp-type plant bundling device (P) inconvenient to use. In view of this, the inventors have designed a branch bundling machine to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a branch tying machine, which has the advantages of achieving reciprocating motion of the movable jaws through mechanisms such as ratchets, and the motion process is relatively continuous and the construction cost is relatively low.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a branch binding machine, comprising a body, a handle, an articulated arm, a movable blade, a movable jaw, a fixed clamping jaw and a spiral bender, the body being provided with a force spring that always applies a force to the movable jaw to move toward the fixed clamping jaw, the movable jaw being sleeved on the spiral bender and moving along the extension direction of the spiral bender, the movable jaw being provided with a sliding groove on one side of the spiral bender, the body being rotatably provided with a first ratchet that acts on the sliding groove, the first ratchet being provided with a second ratchet coaxial with the first ratchet at one end away from the sliding groove, the articulated arm being rotatably provided with a pawl rocker that acts on the second ratchet, the pawl rocker being provided with a tension spring at one end away from the rotating shaft of the articulated arm, one end of the tension spring being connected to the pawl rocker, the other end of the tension spring being connected to the body and always applying a force to the pawl rocker toward the second ratchet.

[0007] By adopting the above technical solution, when the operator presses the handle, the articulated arm rotates along the rotation axis between it and the machine body, and drives the movable blade to close with the fixed clamping claw; during the rotation of the articulated arm, the articulated arm drives the pawl rocker to move, and the pawl rocker is under the action of the articulated arm rotation axis, and the end of the pawl rocker away from the rotation axis is always exerted toward the second ratchet by the tension spring, the pawl rocker applies a force to the second ratchet wheel, so that the second ratchet wheel rotates along the direction of the movable jaw away from the fixed clamping claw, and the second ratchet wheel rotates in the process of rotation. The first ratchet is driven to rotate, causing the first ratchet to rotate in the sliding groove and exerting a force on the movable jaw away from the fixed jaw. The movable jaw moves away from the fixed jaw under the action of the first ratchet and exerts pressure on the force spring, causing the force spring to be further compressed. When the one-way tooth of the first ratchet disengages from the sliding groove, the force spring resets and exerts a force on the movable jaw toward the fixed jaw. The movable jaw moves toward the fixed jaw and fixes the wire loop between the movable jaw and the fixed jaw, thereby completing the grabbing of the wire loop.

[0008] In summary, the above-mentioned force spring, first ratchet, second ratchet, pawl rocker, and tension spring are arranged, and the pawl rocker and tension spring drive the second ratchet to rotate unidirectionally. The first ratchet rotates in the sliding groove under the action of the second ratchet and applies a force to the movable jaw away from the fixed clamping jaw through the unidirectional teeth, and provides power for resetting the movable jaw under the action of the force spring, which can realize the grasping of the wire loop, thereby achieving the purpose of realizing the reciprocating motion of the movable jaw through the ratchet and other mechanisms, and the movement process is relatively continuous and the construction cost is relatively low.

[0009] The present invention is further configured as follows: the first ratchet, the second ratchet and the pawl rocker are symmetrically arranged along the movable jaw, the two first ratchets and the two second ratchets are fixed together, the two pawl rockers are integrally formed, and the tension spring is arranged between the two pawl rockers.

[0010] By adopting the above technical solution, the first ratchet, the second ratchet and the pawl rocker are symmetrically arranged along the movable jaw, and the two first ratchets and the two second ratchets are fixed together, so that the first ratchet and the second ratchet can run synchronously, and the force applied to the movable jaw is more stable.

[0011] The utility model is further configured as follows: a hook ring groove is provided between the two first ratchets, and the tension and retraction spring is rotatably provided on the hook ring groove at one end away from the pawl rocker.

[0012] By adopting the above technical solution, the setting of the hook ring groove and one end of the tension spring being set on it can ensure that the force applied by the tension spring to the pawl rocker is always toward the axis of the second ratchet, making it easier for the pawl rocker to apply force to the second ratchet.

[0013] The utility model is further configured as follows: the movable jaw is provided with a guide groove extending along the moving direction thereof, and the machine body is provided with a guide rod matched with the guide groove.

[0014] By adopting the above technical solution, the setting of the guide groove and the guide rod can guide the movable jaw during its movement, making the movable jaw more stable during the movement.

[0015] In summary, the utility model has the following advantages:

[0016] By setting the force spring, the first ratchet, the second ratchet, the pawl rocker and the tension spring, the pawl rocker and the tension spring drive the second ratchet to rotate in one direction. The first ratchet rotates in the sliding groove under the action of the second ratchet and applies a force to the movable jaw away from the fixed clamping jaw through the one-way teeth. The force spring provides power for resetting the movable jaw, which can realize the grasping of the wire loop, thereby achieving the purpose of realizing the reciprocating motion of the movable jaw through the ratchet and other mechanisms, and the motion process is relatively continuous and the construction cost is relatively low.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] A branch tying machine, such as Figure 1 、 2 As shown, it includes a body 1, a handle 2, an articulated arm 3, a movable blade 4, a movable jaw 5, a fixed clamp 6, a binding device 7 and a spiral bender 8. A force spring 9 is installed on the body 1 to always apply a force to the movable jaw 5 to move toward the fixed clamp 6, and the force spring 9 is sleeved on the spiral bender 8 and is located at the end of the movable jaw 5 away from the fixed clamp 6. One end of the force spring 9 is tightly pressed against the body 1, and the other end is tightly pressed against the movable jaw 5; the movable jaw 5 is sleeved on the spiral bender 8 and moves along the extension direction of the spiral bender 8. The movable jaw 5 is located on one side of the spiral bender 8 and is provided with a sliding groove 10. A spring 9 is rotatably installed on the body 1 to contact the sliding groove. A first ratchet 11 acts on the shifting groove 10, and the rotating shaft of the first ratchet 11 is perpendicular to the axis of the spiral bender 8. A second ratchet 12 coaxial with the first ratchet 11 is installed at one end of the first ratchet 11 away from the sliding groove 10. A pawl rocker 13 that acts on the second ratchet 12 is rotatably installed on the articulated arm 3, and the rotating shaft of the pawl rocker 13 is parallel to the rotating shaft of the first ratchet 11. A tension spring 14 is installed at one end of the pawl rocker 13 away from the rotating shaft of the articulated arm 3, one end of the tension spring 14 is connected to the pawl rocker 13, and the other end of the tension spring 14 is connected to the body 1 and always applies a force toward the second ratchet 12 to the pawl rocker 13.

[0023] Further, such as Figure 2 、 3 As shown, the movable jaw 5 is provided with a guide groove 15 extending along its moving direction, and the body 1 is provided with a guide rod 16 that matches the guide groove 15, which can guide the movable jaw 5 during its movement, so that the movable jaw 5 is more stable during the movement.

[0024] like Figure 2 、 3As shown, the first ratchet 11, the second ratchet 12, and the pawl rocker 13 are symmetrically arranged along the movable jaw 5. The two first ratchet wheels 11 and the two second ratchet wheels 12 are fixed together. The two pawl rockers 13 are integrally formed, and the tension spring 14 is disposed between the two pawl rockers 13. By symmetrically arranging the first ratchet 11, the second ratchet 12, and the pawl rocker 13 along the movable jaw 5 and fixing the two first ratchet wheels 11 and the two second ratchet wheels 12 together, the first ratchet 11 and the second ratchet 12 can operate synchronously, and the force applied to the movable jaw 5 is more stable.

[0025] Furthermore, a hook ring groove 17 is provided between the two first ratchets 11, and the tension spring 14 is rotatably installed on the hook ring groove 17 away from one end of the pawl rocker 13. The setting of the hook ring groove 17 and the setting of one end of the tension spring 14 on it can ensure that the force applied by the tension spring 14 on the pawl rocker 13 is always toward the axis of the second ratchet 12, so that the pawl rocker 13 can exert a force on the second ratchet 12.

[0026] The working process and beneficial effects of the utility model are as follows:

[0027] When the operator presses the handle 2, the articulated arm 3 rotates along the axis between it and the body 1, and drives the movable blade 4 to close with the fixed clamp 6; during the rotation of the articulated arm 3, the articulated arm 3 drives the pawl rocker 13 to move, and the pawl rocker 13 is under the action of the axis of the articulated arm 3, and the end of the pawl rocker 13 away from its axis is always exerted toward the second ratchet 12 by the tension spring 14, the pawl rocker 13 applies a force to the second ratchet 12, so that the second ratchet 12 rotates along the direction of the movable jaw 5 away from the fixed clamp 6, and the second ratchet 12 drives the second ratchet 12 to rotate in the process of rotation. A ratchet 11 rotates, causing the first ratchet 11 to rotate in the sliding groove 10, and applies a force on the movable jaw 5 away from the fixed jaw 6. Under the action of the first ratchet 11, the movable jaw 5 moves away from the fixed jaw 6 and applies pressure to the force spring 9, causing the force spring 9 to be further compressed; and when the one-way teeth of the first ratchet 11 disengage from the sliding groove 10, the force spring 9 resets and applies a force on the movable jaw 5 toward the fixed jaw 6. The movable jaw 5 moves toward the fixed jaw 6 and fixes the wire loop between the movable jaw 5 and the fixed jaw 6, thereby completing the grabbing of the wire loop.

[0028] In summary, the above-mentioned force spring 9, first ratchet 11, second ratchet 12, pawl rocker 13, and tension spring 14 are set, and the pawl rocker 13 and the tension spring 14 drive the second ratchet 12 to rotate in one direction. The first ratchet 11 rotates in the sliding groove 10 under the action of the second ratchet 12 and applies a force to the movable jaw 5 away from the fixed clamping jaw 6 through the one-way teeth, and provides power for resetting the movable jaw 5 under the action of the force spring 9, which can realize the grasping of the wire loop, thereby achieving the purpose of realizing the reciprocating motion of the movable jaw 5 through the ratchet and other mechanisms, and the movement process is relatively continuous and the construction cost is relatively low.
