DETAILED DESCRIPTION

[0021] The following is combined with Figures 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a grafting device for seedling planting. Figures 1-4A grafting device for seedling planting, comprising a fixing plate 1, the outer wall of the fixing plate 1 is provided with two arc-shaped clamping blocks 3 through a clamping mechanism, the outer walls of the two arc-shaped clamping blocks 3 opposite to each other are bonded with sponge pads 4, and the sponge pads 4 can play a buffering and protective role to prevent the outer wall of the seedling from being damaged due to excessive clamping force of the two arc-shaped clamping blocks 3;

[0023] The clamping mechanism includes two moving blocks 2 installed on the outer wall of the fixed plate 1 and moving synchronously relative to each other. The moving blocks 2 are fixedly connected to the arc-shaped clamping block 3. The outer walls opposite to each other of the two moving blocks 2 are fixedly connected to racks 6. The middle outer wall of the fixed plate 1 is rotatably connected to a gear 9, which meshes with the two racks 6.

[0024] A locking mechanism is installed on the outer wall of the fixed plate 1 on the side away from the gear 9, which is used to lock the clamping mechanism. The locking mechanism includes a ratchet 10 rotatably connected to the middle outer wall of the fixed plate 1. A pawl 14 is rotatably connected to the outer wall of the fixed plate 1 through a rotating shaft. The pawl 14 is fixedly connected to the outer wall on the side away from the fixed plate 1 with a lever 15. The lever 15 is used to drive the pawl 14 to rotate, and the end of the pawl 14 abuts against the tooth groove of the outer wall of the ratchet 10. An elastic sheet 16 is also fixedly installed on the outer wall of the fixed plate 1, and one end of the elastic sheet 16 abuts against the top of the pawl 14.

[0025] The middle inner wall of the fixed plate 1 is rotatably connected with a transmission shaft 8, one end of the transmission shaft 8 is fixedly connected to the axis of the gear 9, and the other end of the transmission shaft 8 is fixedly connected to the axis of the ratchet 10. The transmission shaft 8 can transmit the rotation of the ratchet 10 to the gear 9, thereby driving the gear 9 to rotate.

[0026] A bracket 11 is fixedly connected to the outer wall of the fixed plate 1 on the side away from the gear 9, and a connecting shaft 12 is rotatably connected to the middle inner wall of the bracket 11. One end of the connecting shaft 12 is fixedly connected to the axial outer wall of the ratchet 10, and the other end of the connecting shaft 12 is fixedly connected to a handle 13.

[0027] The outer wall of the fixed plate 1 on one side away from the bracket 11 is fixedly connected to two guide rails 5, and the moving block 2 is slidably connected to the outer walls of the two guide rails 5. The guide rails 5 play a guiding and limiting role in the movement of the moving block 2, so that the moving block 2 can move linearly stably.

[0028] The opposite outer walls of the two moving blocks 2 are provided with a through avoidance hole 7, which corresponds to the rack 6, and the ends of the two racks 6 away from the moving block 2 pass through the avoidance hole 7. When the two racks 6 move closer to each other, they can pass through the avoidance hole 7 to prevent the outer wall of the moving block 2 from hindering the movement of the rack 6.

[0029] The implementation principle of a grafting device for seedling planting in an embodiment of this application is as follows: When in use, place the two arc-shaped clamping blocks 3 at the part to be grafted, and then rotate the handle 13. The handle 13 drives the ratchet wheel 10 to rotate through the connecting shaft 12, and the ratchet wheel 10 drives the gear 9 to rotate through the transmission shaft 8;

[0030] Refer to Figure 2 , when the gear 9 rotates counterclockwise, it drives the two racks 6 engaged with it to move closer to each other. The two racks 6 synchronously pull the two moving blocks 2 to move relatively, and the two moving blocks 2 drive the two arc-shaped clamping blocks 3 to clamp the grafting part;

[0031] Refer to Figure 4 , when the ratchet wheel 10 rotates, the locking mechanism is automatically triggered. Specifically: when the ratchet wheel 10 rotates clockwise, the top of the pawl 14 will slide on the tooth grooves on the outer wall of the ratchet wheel 10 and does not prevent it. And under the elastic force generated by the elastic piece 16, the end of the pawl 14 continuously abuts against the tooth grooves on the outer wall of the ratchet wheel 10. When the ratchet wheel 10 rotates counterclockwise, the end of the pawl 14 abuts against the locking surface of the tooth grooves on the outer wall of the ratchet wheel 10, and the ratchet wheel 10 cannot rotate counterclockwise, thus restricting the rotation direction of the ratchet wheel 10. When the ratchet wheel 10 can only rotate clockwise, it drives the gear 9 to rotate clockwise through the transmission shaft 8. The gear 9 drives the two racks 6 to always move closer to each other and cannot drive the two racks 6 to move away from each other. At this time, the two moving blocks 2 drive the arc-shaped clamping blocks 3 to always clamp the grafting part and are not easy to fall off;

[0032] It should be noted that Figure 2 and Figure 4 have different perspectives, so the rotation direction of the gear 9 is different. Figure 4 In Figure 2 , the gear 9 rotates clockwise and can drive the two racks 6 to move closer to each other, while in

[0033] the gear 9 rotates counterclockwise and can drive the two racks 6 to move closer to each other; Figure 4 When it is necessary to release the clamping, just push up the lever 15 to make the elastic piece 16 rotate upward around its rotating shaft until the end of the elastic piece 16 disengages from the tooth grooves on the outer wall of the ratchet wheel 10.
