Description

Technical Field

[0001] The utility model relates to the technical field of jujube tree grafting, in particular to a rotary clamp for jujube tree grafting. Background Art

[0002] Grafting is one of the artificial propagation methods of plants. It is to graft the branches or buds of one plant onto the stem or root of another plant so that the two parts grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. Grafting is carried out by utilizing the healing function of plants after being injured. The spiral clamp is mainly used as a device to fix the scion and the rootstock in the grafting of jujube trees, which can effectively improve the success rate of jujube tree grafting.

[0003] The spiral clamp completes the grafting by fixing the scion and the rootstock, but the existing spiral clamp cannot control the clamping force during use. If the clamping force is too tight, it may cause damage to the internal tissue. If the clamping force is too small, it may become loose and fall. In view of this, we propose a spiral clamp for jujube tree grafting. Summary of the invention

[0021] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a rotary clamp for jujube tree grafting, comprising a mounting block 1, a rotating rod 2 is rotatably connected to the inner wall of the mounting block 1, a splint 3 is fixedly installed on the outer wall of the rotating rod 2, the grafting part is fixed by placing it between the two splints 3, a first fixing block 4 and a second fixing block 5 are respectively fixedly installed on the outer walls of the splints 3, a fastening bolt 6 is rotatably connected inside the first fixing block 4, a threaded hole 7 is provided on the second fixing block 5, the first fixing block 4 and the second fixing block 5 can be moved toward each other by twisting the fastening bolt 6 counterclockwise, and a control mechanism 8 is provided on the splint 3.

[0022] In this embodiment, a control mechanism 8 is provided on the splint 3. By clamping the block 89 in the control mechanism 8 inside the clamping groove 811, the cylinder 810 can drive the fastening bolt 6 to no longer continue to rotate counterclockwise, preventing the fastening bolt 6 from continuing to rotate and the two extrusion plates 83 from continuing to clamp the grafting part, resulting in excessive clamping force, which may cause the internal tissue to be compressed and damaged, affecting subsequent growth. At the same time, by turning the fastening bolt 6 counterclockwise, the fastening bolt 6 can drive the cylinder 810 to rotate clockwise to squeeze the arc surface of the block 89, so that the limit is released, making it convenient to continue to turn the fastening bolt 6 to complete the disassembly, and convenient to use the device again.

[0023] In this embodiment, the control mechanism 8 includes an extrusion rod 81, which passes through the interior of the splint 3. A return spring 82 is sleeved on the outer wall of the extrusion rod 81. One end of the return spring 82 is fixedly connected to the outer wall of the extrusion rod 81, and the other end of the return spring 82 is fixedly connected to the outer wall of the splint 3. An extrusion plate 83 is fixedly installed on the end of the extrusion rod 81. The two internal extrusion plates 83 are driven to move toward each other and contract through the two splints 3, so that the two extrusion plates 83 can clamp and fix the grafting. A bent plate 84 is fixedly installed on the outer wall of the extrusion plate 83. The extrusion plate 83 can drive the bent plate 84 to move leftward relative to the splint 3 by extrusion. The bent plate 84 passes through the interior of the splint 3 and the first fixed block 4 respectively. A hinge block 85 is fixedly installed on the bottom wall of the bent plate 84. A round rod 86 is rotatably connected to the inner wall of the hinge block 85. The outer wall of the round rod 86 It is fixedly connected to one end of the torsion spring 87, and the other end of the torsion spring 87 is elastically connected to the inner wall of the hinge block 85. A connecting plate 88 is fixedly installed on the outer wall of the round rod 86, and the connecting plate 88 is set in a bent shape. A clamping block 89 is fixedly installed on the bottom wall of the connecting plate 88. The clamping block 89 is clamped in the inside of the clamping groove 811, so that the cylinder 810 can no longer drive the fastening bolt 6 to rotate counterclockwise, preventing the two extrusion plates 83 from continuing to clamp the grafting part and causing excessive clamping force. One side of the clamping block 89 is set in an arc shape, and the cylinder 810 is driven by the fastening bolt 6 to rotate clockwise to squeeze the arc surface of the clamping block 89, so that the limit can be released to facilitate the disassembly of the device. The outer wall of the fastening bolt 6 is fixedly sleeved with a cylinder 810, and a clamping groove 811 is opened on the cylinder 810, and the clamping groove 811 is opened in a circular array on the cylinder 810.

[0024] In this embodiment, the grafting part is placed between the two clamping plates 3, and then the fastening bolt 6 is screwed counterclockwise, and the first fixing block 4 and the second fixing block 5 are moved toward each other through the setting of the threaded hole 7, so that the two clamping plates 3 drive the two internal extrusion plates 83 to move toward each other and contract, so that the two extrusion plates 83 clamp and fix the grafting part, and at the same time, the extrusion plate 83 drives the bent plate 84 to move leftward relative to the clamping plate 3 through extrusion, and then the bent plate 84 drives the hinge block 85 on the bottom wall to move leftward, and then the hinge block 85 drives the clamping block 89 on the bottom wall of the connecting plate 88 to move toward the direction of the cylinder 810, and finally the clamping block 8 9 is clamped in the inside of the clamping groove 811, so that the cylinder 810 can no longer drive the fastening bolt 6 to rotate counterclockwise, and then the two extrusion plates 83 are stopped from clamping the grafting part through the clamping to prevent the clamping force from being too large. When the grafting front growth molding is completed and the device needs to be disassembled, the fastening bolt 6 is turned counterclockwise, and then the cylinder 810 is driven by the fastening bolt 6 to rotate clockwise to squeeze the arc surface of the clamping block 89, so that the clamping block 89 drives the connecting plate 88 to rotate around the round rod 86 to release the limit, and then the disassembly is completed by continuing to turn the fastening bolt 6, which facilitates the disassembly of the device.
