The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] Example 1

[0043] Please see Figure 1 This utility model provides a nail-pushing device for use on a branch tying machine. It is installed on the branch tying machine and can provide the branch tying machine with binding nails when the branch tying machine is performing the nailing action, thereby completing the nailing action of the binding nails.

[0044] The branch tying machine includes a clamping device 1, an arched frame 2, a handle 3, a frame 4, a nail-pushing device 5, and a strapping box 6. The arched frame 2 is rotatably connected to the frame 4, and the handle 3 can drive the arched frame 2 to rotate relative to the frame 4. The clamping device 1 is provided at the front end of the arched frame 2, the nail-pushing device 5 is arranged on the upper part of the frame 4, and the strapping box 6 is arranged on the lower part of the frame 4. The clamping device 1 pulls the strapping from the front end of the frame 4. The nail-pushing device 5 contains several strapping nails arranged in rows. The strapping nails are pressed out through the nail outlet 130 at the front end of the nail-pushing device 5 and fasten the strapping.

[0045] Furthermore, such as Figure 2-4 As shown, the pusher device 5 includes a nail box 100 and a pusher assembly 200. The nail box 100 is elongated and includes a box body 110 and a dust cover 160. The box body 110 and the dust cover 160 form a cavity structure. A groove 120 for placing strap nails is provided inside the nail box 100. A nail outlet 130 is provided at the front end of the groove 120. Only one strap nail can pass through the nail outlet 130 at a time. The pusher assembly pushes a row of strap nails to slide forward in the groove 120. The individual strap nail is pressed out through the nail outlet 130 and fastens and fixes the strap.

[0046] The pusher assembly 200 is slidably disposed within the groove 120 for pushing the strap pin; as Figure 5 As shown, the push-nail assembly 200 includes a push-nail head 210, a support rod 220, a spring 230, and a spring piece 240 connected in sequence. The push-nail head 210 is slidably sleeved on the front end of the support rod 220, and the rear end of the support rod 220 is connected to the spring piece 240. The spring 230 is sleeved on the outer periphery of the support rod 220 and abuts against the push-nail head 210. The two ends of the spring 230 are in contact with the push-nail head 210 and the spring piece 240, respectively. A limiting structure is provided on the top of the spring piece 240, and the limiting structure is engaged with the fixing device of the nail box 100.

[0047] When attaching staples, first pull the staple pusher assembly 200 out of the staple box 100 (e.g., Figure 3As shown, the opening at the end of the nail box 100 is opened, and rows of strap nails slide from the opening of the nail box 100 into the groove 120. Then, the pusher head 210 is pushed against the rows of strap nails and pushed to the front end of the pusher head 210. The pusher assembly 20 is further pushed until the limiting structure of the spring piece 240 is engaged in the fixing device of the nail box 100. At this time, the pusher assembly 20 is fixed, and the pusher head 210 compresses the spring 230, so that the spring 230 has driving potential energy on the pusher head 210, which can drive the strap nails in the groove 110 to move towards the nail outlet 130. Under the action of the spring 230, the pusher head 210 applies a preload force to the strap nails to always be against the nail outlet 130.

[0048] The limiting structure and fixing device at the top of the spring piece 240 cooperate to prevent the push pin assembly 20 from sliding backward out of the slide groove 120. The limiting structure and fixing device can be various snap-fit ​​structures. For example, the limiting structure provided in this embodiment is a wedge-shaped pressure protrusion 241. The pressure protrusion 241 is a wedge-shaped structure that is lower in the front and higher in the back. The height of the pressure protrusion 241 increases from front to back (e.g., ...). Figure 6 (As shown); the fixing device on the nail box 100 is a frame-shaped card holder 140. The card holder 140 is located at the top of the rear end of the nail box 100. When the pressure protrusion 241 of the spring piece 240 slides into the card holder 140, due to the elastic tendency of the spring piece 240 to move upward, the card holder 140 firmly abuts against the rear end face of the pressure protrusion 241, preventing the spring piece 240 from sliding backward, thereby fixing the push nail assembly 20.

[0049] In another embodiment, a square hole can be provided in the card holder 140, and the pressure protrusion 241 can be inserted into the square hole to fix the push pin assembly 20.

[0050] When it is necessary to pull the pusher assembly 200 out of the nail box 100, in order to facilitate the release of the fixing effect of the card holder 140 on the spring piece 240, the spring piece 240 is set as V-shaped. The V-shaped spring piece 240 has elastic deformation that moves up and down. Pressing the spring piece 240 down prevents the rear end face of the pressure protrusion 241 from contacting the card holder 140, so that the pusher assembly 20 can be easily pulled out of the slide groove 120.

[0051] like Figure 5-8 In the technical solution of this utility model, the push pin assembly 200 includes a push pin head 210, a support rod 220, a spring 230, and a spring piece 240. The bottom of the spring piece 240 is provided with a through hole 242, and the support rod 220 is fixed to the through hole on the abutment joint 240. The fixing method can be snap-fit, adhesive, welding, threaded connection, or any other form. For example, when using a threaded connection (such as...) Figure 5-7As shown, a nut 243 is fixedly connected inside the through hole 242. A limiting post 222 is provided at the front end of the support rod 220, and a thread 221 is provided at the rear end of the support rod 220. The nut 243 is threadedly connected to the thread 221 at the rear end of the support rod 220. When a snap-fit ​​connection is used, a fixing groove is provided at the rear end of the support rod 220. After the support rod 220 passes through the through hole of the spring piece 240, the fixing groove snaps and fixes with the through hole of the spring piece 240.

[0052] To prevent the pusher head 210 from detaching from the front end of the support rod 220, a through hole is provided inside the pusher head 210, and a limiting groove 211 is provided at the front end of the through hole. The width of the limiting groove 211 is greater than the diameter of the through hole. A limiting post 222 is provided at the front end of the support rod 220. The diameter of the limiting post 222 is greater than the diameter of the main body of the support rod 220. The main body of the support rod 220 and the through hole are clearance-fitted. When the pusher head 210 moves to the front end of the support rod 220, the limiting post 222 is slidably connected in the limiting groove 211. The limiting post 222 can prevent the pusher head 210 from detaching from the front end of the support rod 220.

[0053] The front end face of the pusher head is convex, concave, or flat, and the limiting groove penetrates the front end face, such as... Figure 8 As shown, the front end of the pusher head 210 provided by this utility model is flat, which has high strength and is not easily deformed.

[0054] like Figure 9 As shown, when the pusher head 210 pushes the binding nail towards the nail outlet 130, a nail guard plate 150 is provided on the nail box 100 at the relative position of the nail outlet 130 to protect the binding nail, prevent the binding nail from falling out of the slide groove 110, improve the stability of the binding nail, and also effectively improve the nailing accuracy and nailing efficiency of the branch binding machine.

[0055] Furthermore, the nail box 100 provided in this embodiment consists of a box body 110 and a dust cover 160 forming a cavity structure, wherein the box body 110 and the dust cover 160 are fixed by welding (e.g., Figure 9 As shown, the strap pins slide in the grooves inside the cavity, and the cavity structure can protect the strap pins from dust.

[0056] Working principle of branch tying machine

[0057] The tying machine includes a standby state, a strap gripping state, a strap tying state, and a strap binding and cutting state. In the standby state, the bow-shaped frame 2 is in the open position relative to the frame 1. In the strap gripping state, force is applied by squeezing the handle 3, and the bow-shaped frame 2 rotates downward clockwise relative to the frame 4. As the bow-shaped frame 2 rotates, the clamping device 1 contacts the front end of the frame 4, thus clamping the strap. In the branch-tying state, release the pressure on the handle 3 and rotate the bow-shaped frame 2 counterclockwise upwards. As the bow-shaped frame 2 rotates, the binding strap is stretched. After inserting the branch-tying machine into the desired branch position, let the binding strap wrap around the branch to complete the tying. In the binding and cutting state, after adjusting the binding strap to the appropriate position on the branch, press the handle 3. The bow-shaped frame 2 moves downwards again until the clamping device 1 contacts the front end of the frame 4. Press the handle 3 further, and the binding strap nail in the nail pusher 5 attaches to the binding strap from the nail outlet. Release the handle 3 again, and the bow-shaped frame 2 returns to the open position, thus completing one branch-tying operation. Repeating the above actions can achieve branch-tying operations for various branches.

[0058] Example 2

[0059] Unlike Embodiment 1, the fixing method of the box body 110 and the dust cover 160 is different in this embodiment, such as... Figure 10 As shown, the box body 110 and the dust cover 160 are fixed by snap-fit. The dust cover 160 has a first limiting edge 170 on each side, and the first limiting edge 170 has a snap-fit ​​interface 171, which is a square hole structure. The box body 110 has a corresponding snap-fit ​​block 111, which is a wedge structure. By pressing the dust cover 160, the snap-fit ​​block 111 is snapped into the snap-fit ​​interface 171. The dust cover 160 has an upward elastic force, so that the lower part of the snap-fit ​​interface 171 is firmly pressed against the lower surface of the snap-fit ​​block 111, thus fixing the dust cover 160. Furthermore, in order to improve the stability of the dust cover 160, multiple first limiting edges 170 can be provided. In this embodiment, a total of four first limiting edges 170 are provided, with two first limiting edges 170 provided at both the front and rear ends of the dust cover 160. By setting the box body 110 and the dust cover 160 to a snap-fit ​​fixing method, when a nail is stuck, the strap nail stuck in the slide groove 120 can be easily removed.

[0060] Example 3

[0061] Unlike Embodiment 1, the fixing method of the box body 110 and the dust cover 160 is different in this embodiment, such as... Figure 11-12As shown, the box body 110 and the dust cover 160 are fixed by snap-fit. The dust cover 160 has second limiting edging 180 on both sides, with snap-fit ​​holes 181 on the second limiting edging 180. A notch 182 is formed at the bottom of the snap-fit ​​hole 181, and a corresponding locking post 112 is provided on the box body 110. The width of the notch 182 is smaller than the diameter of the locking post 112, preventing the locking post 112 from dislodging from the snap-fit ​​hole 181. By pressing down on the dust cover 160, the locking post 112 is forced into the snap-fit ​​hole 181 from the notch 182. After sliding in, the notch 182 prevents the locking post 112 from sliding out, thus completing the fixation of the dust cover 160.

[0062] Furthermore, in order to improve the stability of the dust cover 160, multiple second limiting edges 180 can be provided. In this embodiment, a total of four second limiting edges 180 are provided, with two second limiting edges 180 provided at both the front and rear ends of the dust cover 160. By setting the box body 110 and the dust cover 160 to a snap-fit ​​fixing method, when a nail is stuck, the strap nail stuck in the slide groove 120 can be easily removed.
