Description

Technical Field

[0001] The utility model belongs to the technical field of branch binding machines, in particular to a nail-out structure of a branch binding machine. Background Art

[0002] The branch tying machine, also known as the vine tying machine, is a hand tool used to tie vine plants such as tomatoes, cucumbers, grapes, peppers, eggplants, and gardening.

[0003] Most of the binding machines use nails to fix the two ends of the binding straps. Its structure is similar to that of a stapler, such as the Chinese utility model patent CN 202220899874.5 discloses a branch binding machine and a binding nail. The branch binding machine includes a frame body, a rocker arm, a handle and a nail storage box. One end of the rocker arm is rotatably arranged on the frame body, and the handle is respectively connected to the rocker arm and the frame body, and is arranged to press the handle to drive the other end of the rocker arm to rotate toward the frame body, and the other end of the rocker arm can bite and pull out the binding nail from the frame body. The nail storage box is fixedly arranged on the frame body, and the nail outlet of the nail storage box is arranged near the position where the frame body receives and withdraws the binding nail; wherein, the nail storage box is used to store binding nails with a threading arm length of 3.0-3.5mm and a pressure arm length of 5.0-6.0mm. By controlling the size of the binding nails and cooperating with the branch binding machine, the binding nails under this size can effectively improve the nailing accuracy, thereby avoiding the situation where the binding nails are detached from the binding strap. While improving the nailing accuracy of the branch binding machine, it can also effectively reduce the material cost of the binding nails.

[0004] According to the specification, in the above structure, the front part of the nail storage box is bent to form a first nail guard plate and a second nail guard plate, and a nail blocking plate is provided between the first nail guard plate and the second nail guard plate. However, since the bending can easily affect the structural strength of the nail storage box, the first nail guard plate and the second nail guard plate can be easily deformed after long-term use, thereby causing the size of the nail outlet to change. During use, more nails will be produced, affecting the normal use of the branch binding machine. Summary of the Invention

During the production process of this structure, the box body 1 and the nail storage seat 2 can be produced separately, the structure is simple, and the production and processing of the nail storage box is convenient. The producer can use higher-strength materials to produce the nail storage seat 2, which is beneficial to extending the service life of the nail storage seat 2 and avoiding deformation of the nail outlet groove 23 after long-term use, which affects the normal use of the branch binding machine.

[0038] The nail storage seat 2 described in the present invention includes a fixedly connected connecting member 21 and a guide member 22, and the nail outlet groove 23 is formed between the connecting member 21 and the guide member 22. The connecting member 21 is fixedly connected to the box body 1, and the connecting member 21 is provided with a guide groove 217 connecting the nail storage cavity 11 and the nail outlet groove 23. The thrust spring 5 can drive the row of nails 6 to pass through the guide groove 217 and enter the nail outlet groove 23. In this structure, the nail outlet groove 23 is formed by combining the connecting member 21 and the guide member 22, which is convenient for the production and processing of the nail outlet groove 23, and is convenient for improving the accuracy and structural strength of the nail outlet groove 23. It can avoid the deformation of the nail outlet groove 23 and the occurrence of excessive nails, and ensure the normal use of the nail outlet structure.

[0039] In this embodiment, the width of each row of nails 6 is c, and the width of the nail outlet slot 23 is d. The width d of the nail outlet slot 23 is greater than the width c of the row of nails 6, and the width d of the nail outlet slot 23 is less than twice the width c of the row of nails 6, so that only one row of nails 6 can be discharged from the nail outlet slot 23 at a time. This structure can avoid the occurrence of multiple nails during use, and the row of nails 6 is not easily stuck in the nail outlet slot 23, which is convenient for users to use.

[0040] The nail storage seat 2 extends to the front of the box body 1 to form a mounting plate 218, and a belt guide piece 7 is detachably provided on the mounting plate 218. A belt guide groove 71 for the branch binding machine belt to pass through is formed between the belt guide piece 7 and the mounting plate 218. The setting of the belt guide piece 7 and the mounting plate 218 facilitates the flexible setting of the belt guide groove 71, and the belt guide groove 71 is directly set on the nail output structure to facilitate the assembly and production of the branch binding machine.

[0041] The connecting member 21 in this embodiment extends toward the front of the box body 1 to form two groups of mounting plates 218. The two groups of mounting plates 218 are L-shaped and combined to form a C-shaped structure. The guide plate 7 is detachably arranged in the C-shaped structure and is detachably connected to the two groups of mounting plates 218 respectively. In this embodiment, the guide member 22 is arranged in the C-shaped structure to avoid the guide member 22 being subjected to force and causing the guide member 22 to be loosely installed. The guide member 22 extends toward the middle of the C-shaped structure to form a positioning portion 222. During use, the nail-out structure will undergo relative movement. The positioning portion 222 can abut against the main body of the branch tying machine to reset the nail-out structure to a specific position of the main body of the branch tying machine, and make the hook belt structure move to the same position of the binding belt each time it is triggered, which is convenient for users to use.

[0042] Preferably, a groove 221 and a tightening plane 215 are respectively provided on the guide member 22 and the connecting member 21. The tightening plane 215 abuts against the side of the groove 221 and is combined with the groove 221 to form the nail output groove 23. This structure can avoid the misalignment of the connecting member 21 and the guide member 22 during installation, which affects the relative movement of the row of nails 6 in the nail output groove 23, facilitates the production and assembly of the nail output structure, and can avoid the loose connection between the connecting member 21 and the guide member 22 after long-term use, which affects the normal use of the nail output structure.
