[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1 , this embodiment provides a clamping mechanism.

[0029] The limiting platform 100 is a rectangular structure, made of high-strength aluminum alloy material, and has the characteristics of being light and strong. The surface of the limiting platform 100 can be provided with anti-skid patterns to ensure that the pressed object does not slide during the pressing process.

[0030] The adjusting rod 200 is a hollow cylindrical structure made of stainless steel with good corrosion resistance and wear resistance. One end of the adjusting rod 200 is fixed on the limiting platform 100, and the other end is provided with a handle of a suitable shape for the operator to rotate and adjust. The outer wall of the adjusting rod 200 is provided with a spiral pattern, and by rotating the handle, the adjusting rod 200 generates linear motion on the limiting platform 100.

[0031] The support rods 201 are two cylindrical structures symmetrically arranged on both sides of the limiting platform 100, and are also made of stainless steel. The support rods 201 are used to be fixedly connected to the side walls of the nuclear fuel running structure, thereby providing effective support for the limiting platform 100.

[0032] Place the object to be clamped on one side of the limiting platform 100, rotate the handle of the adjusting pressure rod 200, and make the adjusting pressure rod 200 produce linear motion on the limiting platform 100 until the required clamping force is reached, and the object to be clamped is fixed. When the clamping force reaches the set value, stop rotating the handle, and the clamping mechanism is in a stable state, and the next step can be performed.

[0033] Example 2

[0034] Reference Figures 1 to 3 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0035] This embodiment is a further optimization of claim 1, an improvement of the limit platform 100, and an adjustment screw hole 101 is fixedly opened in the middle of the limit platform 100 in this embodiment, and the adjustment screw hole 101 is used to cooperate with the adjustment pressure rod 200. The limit platform 100 is made of high-strength aluminum alloy material and has good wear resistance and impact resistance. The opening position of the adjustment screw hole 101 is accurately calculated to ensure the balance and stability of the adjustment pressure rod 200 during the pressing process.

[0036] A positioning screw hole 102 is provided on one side of the adjusting screw hole 101, and the support rod 201 passes through the positioning screw hole 102 to penetrate the limiting platform 100. This design enables the support rod 201 to more firmly fix the limiting platform 100 to prevent it from shifting during the pressing process, and a positioning cap 201a is rotatably sleeved on the support rod 201, and the positioning cap 201a is located on the upper and lower sides of the limiting platform 100. The function of the positioning cap 201a is to further lock the position of the support rod 201 to prevent it from accidentally rotating or falling off during use.

[0037] The bottom of the adjusting pressure rod 200 is fixedly connected with a buffer pad 202, which is made of rubber material and has good elasticity and wear resistance. During the pressing process, the buffer pad 202 can absorb and disperse the pressure to protect the pressed object from damage. The top of the adjusting pressure rod 200 is fixedly connected with an adjusting cap 203, which facilitates the user to manually rotate the adjusting pressure rod 200 to achieve precise adjustment of the pressing force.

[0038] Through the design of the adjusting screw hole 101 and the positioning screw hole 102, the quick and accurate installation and adjustment of the adjusting pressure rod 200 and the support rod 201 are achieved. The setting of the positioning cap 201a improves the stability of the support rod 201 and ensures the safety and reliability of the entire clamping mechanism during use. The application of the buffer gasket 202 and the adjusting cap 203 not only improves the flexibility and accuracy of the clamping operation, but also increases the protection measures for the clamped object. The overall structure is simple, easy to maintain and replace, and reduces the cost of use.

[0039] Example 3

[0040] Reference Figures 1 to 5 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0041] The support sleeve 300 is made of high-strength aluminum alloy material, which is light and durable. The support plate 301 is made of stainless steel, which has good corrosion resistance and can be used in harsh environments for a long time. One side of the support plate 301 is fixedly connected to one end of the support rod 201. This connection method ensures the stable combination of the clamping mechanism and the transfer device, so that the entire device remains stable during the transfer process.

[0042] The sealing design of the cylinder 302 includes sealing ends 302a fixedly arranged on both sides of the cylinder 302. These sealing ends 302a can be flanges, and corresponding sealing structures such as sealing rings are embedded in them. They are made of rubber material and have good sealing performance, which can effectively prevent material leakage or external pollution during transportation.

[0043] A parallel assembly 303 is fixedly provided on one side of the cylinder 302, and a lifting lug 303a is fixedly provided on the top of the parallel assembly 303. The design of the lifting lug 303a facilitates the use of lifting equipment to lift materials, thereby improving the efficiency of transportation. The accommodating channel 304 inside the support sleeve 300 is fixedly provided inside the support sleeve 300. The accommodating channel 304 is located on one side of the buffer gasket 202. The design of the accommodating channel 304 enables the transfer device to adapt to materials of different sizes and shapes, thereby increasing the scope of application of the device. Finally, the buffer gasket 202 can be directly aligned with the nuclear material container in the accommodating channel 304, thereby achieving a good compression and fixing effect.
