[0021] For this specific embodiment, the clamping strip 108 is sleeved on the grafting site, then the limit rod 103 is pulled to move, the limit rod 103 is disengaged from the limit hole 115, thereby canceling the limit of the clamping strip 108, then the clamping strip 108 is pulled to tighten, the clamping strip 108 is clamped with the grafting site, thereby fixing the grafting site, then the limit rod 103 is loosened, under the elastic force of the spring 102, the limit rod 103 returns to the original position again and is adapted with the corresponding limit hole 115, thereby limiting and fixing the clamping strip 108, thereby fixing the device at the grafting site, whereby the device replaces the bolt through the clamping strip 108, improves the efficiency of installation and disassembly, and is high in convenience, can adjust the clamping distance, can adjust the tightness, thereby adapting to grafting objects of different sizes.

[0022] ​The U-shaped plate 105 is arranged at the right end of the shell 101, one end of each of the two connecting rods 107 is fixedly connected with the annular frame 106, the other end of each of the two connecting rods 107 is fixedly connected with the right end of the shell 101, one end of the clamping strip 108 is fixedly connected with the U-shaped plate 105, the other end of the clamping strip 108 penetrates through the annular frame 106 and the U-shaped plate 105, one end of the limiting rod 103 penetrates through the outer wall of the shell 101 and the annular frame 106 and is matched with the corresponding limiting hole 115, the circular ring 104 is fixedly sleeved outside the limiting rod 103 and is located inside the shell 101, and the two ends of the spring 102 are fixedly connected with the inner wall of the shell 101 and the side wall of the circular ring 104 respectively. The clamping strip 108 is sleeved at the grafting site, then the limiting rod 103 is pulled to move, the limiting rod 103 is disengaged from the matching of the limiting hole 115, so that the limiting of the clamping strip 108 is cancelled, then the clamping strip 108 is pulled to tighten, the clamping strip 108 is clamped with the grafting site, so that the grafting site is fixed, then the limiting rod 103 is loosened, under the elastic force of the spring 102, the limiting rod 103 returns to the original position again and is matched with the corresponding limiting hole 115, so that the clamping strip 108 is fixedly limited, so that the device is fixed at the grafting site, so that the device replaces the bolt through the clamping strip 108, the installation and disassembly efficiency is improved, the convenience is high, the clamping distance can be adjusted, the tightness degree can be adjusted, and different sizes of grafting objects can be adapted.

[0023] Secondly, the sliding groove 111 is fixedly connected with the inner wall of the shell 101, one end of the sliding block 112 is slidably matched with the sliding groove 111, and the other end of the sliding block 112 is fixedly connected with the limiting rod 103. When the limiting rod 103 moves, the cooperation of the sliding block 112 and the sliding groove 111 makes the movement of the limiting rod 103 more stable, reduces the shaking condition, and improves the accuracy of the matching with the limiting hole 115.

[0024] Meanwhile, the two moving blocks 114 are slidably matched with the guide rails 113 respectively, and the two moving blocks 114 are arranged at the rear end of the shell 101 respectively. Through the cooperation of the two moving blocks 114 and the guide rails 113, the distance between the two clamping mechanisms can be adjusted by the worker, so that the device has a wider application range when in use.

[0025] In addition, the right end of the limiting rod 103 has a chamfered surface 109. Through the arrangement of the chamfered surface 109, when the clamping strip 108 is tightened, the limiting rod 103 does not need to be pulled again, and only the clamping strip 108 needs to be pulled, so that the clamping strip 108 extrudes the chamfered surface 109, thereby pushing the limiting rod 103 to move. When the clamping strip 108 is tightened, the limiting rod 103 returns to the original position under the elastic force of the spring 102, thereby limiting the clamping strip 108 again.

[0026] In addition, the semicircular arc plate 110 is fixedly connected with the annular frame 106 and is located at the right end of the annular frame 106. Through the arrangement of the semicircular arc plate 110, when the device contacts the grafting site, the wrapping is better, and the contact area is larger, thereby improving the clamping effect.

[0027] In use, the clamping strip 108 is sleeved on the grafting site, then the limiting rod 103 is pulled to move, so that the limiting rod 103 is disengaged from the limiting hole 115, thereby canceling the limiting of the clamping strip 108, then the clamping strip 108 is pulled to tighten, so that the clamping strip 108 clamps the grafting site, thereby fixing the grafting site, then the limiting rod 103 is loosened, and the limiting rod 103 returns to the original position again and is engaged with the corresponding limiting hole 115 under the elastic force of the spring 102, thereby limiting and fixing the clamping strip 108, so that the device is fixed on the grafting site. Therefore, the device replaces the bolt through the clamping strip 108, improves the efficiency of installation and disassembly, is high in convenience, can adjust the clamping distance and the tightness degree, thereby adapting to grafting objects of different sizes. When the limiting rod 103 moves, the limiting rod 103 moves more stably through the cooperation of the sliding block 112 and the sliding groove 111, thereby reducing the shaking condition and improving the accuracy of engagement with the limiting hole 115. Through the cooperation of the two moving blocks 114 and the guide rail 113, the distance between the two clamping mechanisms can be adjusted by the worker, so that the device is more widely applicable in use. Through the arrangement of the chamfered surface 109, when the clamping strip 108 is tightened, the limiting rod 103 does not need to be pulled again, and only the clamping strip 108 needs to be pulled, so that the clamping strip 108 extrudes the chamfered surface 109, thereby pushing the limiting rod 103 to move. When the clamping strip 108 is tightened, the limiting rod 103 returns to the original position under the elastic force of the spring 102, thereby limiting the clamping strip 108 again. Through the arrangement of the semicircular arc plate 110, when the device contacts the grafting site, the wrapping is better, and the contact area is larger, thereby improving the clamping effect.
