[0010] As a further solution of the present invention, the second fixing block is a trapezoidal structure, and a sliding groove matched with the second fixing block is provided on the right side of the partition, so that the partitions can be combined and fixed.

[0011] As a further solution of the present invention, the fixing rod is of an inclined structure, and fixing rods are fixed at equal distances on one side of the partition away from the first fixing block, thereby increasing the stability of the partition and increasing the support of the partition.

[0012] In summary, the present invention includes at least one of the following beneficial technical effects:

[0013] First, the utility model records a device for preventing rice crabs from escaping, which records that by providing a first fixing block and cooperating with a partition, rice crabs are not easy to escape. When the device is placed on the edge of the soil, due to the structure of the first fixing block, the rice crabs cannot be stressed and cannot flip over the partition, thereby preventing the rice crabs from escaping, improving the protective effect of the device, and improving the working efficiency of the device;

[0014] Second, the utility model records a device for preventing rice crabs from escaping, which records that a connecting rod and a fixing rod are provided to make the device more stably fixed, and that the connecting rod is inserted into the ground and the partition is supported by the fixing rod, so that the device is more stable when placed and installed, thereby improving the stability of the device and improving the working efficiency of the device.

[0021] Please refer to Figure 1 -4. A device for preventing rice crabs from escaping, comprising a partition 1, a main mechanism 2 is fixed on the surface of the partition 1, the main mechanism 2 comprises a first fixing block 210, the first fixing block 210 is fixed on the surface of the partition 1, a connecting rod 220 is fixed to the bottom end of the partition 1, a second fixing block 230 is fixed on the surface of the partition 1, and a fixing rod 240 is fixed on the surface of the partition 1.

[0022] The interior of the partition 1 is evenly and evenly provided with circular through holes, the surface of the first fixing block 210 is an arc-shaped structure, and the first fixing block 210 is fixed to the top of the partition 1 to prevent the rice crab from turning over the partition 1;

[0023] The connecting rod 220 is a square structure, and the connecting rod 220 is fixed at the bottom end of the partition 1. The connecting rod 220 is provided with three groups, and the length of the middle group of connecting rods 220 is longer than the connecting rods 220 on both sides. The fixing rod 240 is an inclined structure, and the fixing rod 240 is fixed at an equal distance on one side of the partition 1 away from the first fixing block 210, so that the device is more stable when fixed and is not easy to be displaced;

[0024] The second fixing block 230 is a trapezoidal structure, and a sliding groove adapted to the second fixing block 230 is provided on the right side of the partition 1, so that the device is more stable when combined and connected, thereby improving the expandability of the device.
