[0024] Specifically, the clamping assembly 3 includes a bidirectional trapezoidal lead screw 31, a clamping knob 32, a square slider 33, a connecting block 34, a disassembly and assembly component 35 and a clamping plate 36. Among them, the bidirectional trapezoidal lead screw 31 is arranged inside the installation seat 2, a clamping knob 32 is arranged at one end of the bidirectional trapezoidal lead screw 31, square sliders 33 are symmetrically and threadedly connected to the surface of the bidirectional trapezoidal lead screw 31, a connecting block 34 is arranged at one end of the square slider 33, a disassembly and assembly component 35 is arranged at one end of the connecting block 34, and a clamping plate 36 is arranged at one end of the disassembly and assembly component 35.

[0025] By adopting the above technical solutions, rotating the clamping knob 32, the rotation of the clamping knob 32 drives the rotation of the bidirectional trapezoidal lead screw 31, the rotation of the bidirectional trapezoidal lead screw 31 drives the movement of the square slider 33, the movement of the square slider 33 drives the movement of the connecting block 34, thereby driving the movement of the clamping plate 36, clamping and fixing the device on the maintenance seat 1, so that when the device is used, it is convenient to install the device, improving the convenience of use.

[0026] Specifically, the disassembly and assembly component 35 includes a fixed seat 351, a square insert block 352, a fixed rod 353, a fixed slider 354, and a fixed spring 355. Among them, the fixed seat 351 is arranged at one end of the connecting block 34. The square insert block 352 is inserted above the fixed seat 351. A fixed rod 353 is arranged on one side of the square insert block 352. A fixed slider 354 is arranged on one side of the fixed rod 353. A fixed spring 355 is arranged on one side of the fixed slider 354.

[0027] By adopting the above technical solution, when it is necessary to replace the corresponding clamping plate 36, pull the fixed rod 353. The fixed rod 353 drives the fixed slider 354 to move and compress the fixed spring 355, so that the fixed rod 353 disengages from the fixing hole. Then, the square insert block 352 and the fixed seat 351 can be separated, and thus the clamping plate 36 can be removed.

[0028] Specifically, a support rod is arranged around the surface of the clamping rotating handle 32, and a fastening pad is arranged on one side of the clamping plate 36.

[0030] When this embodiment is in use: Rotate the clamping rotating handle 32. The rotation of the clamping rotating handle 32 drives the rotation of the bidirectional trapezoidal lead screw 31. The rotation of the bidirectional trapezoidal lead screw 31 drives the movement of the square slider 33. The movement of the square slider 33 drives the movement of the connecting block 34, thereby driving the movement of the clamping plate 36 to clamp and fix the device on the maintenance seat 1. When it is necessary to replace the corresponding clamping plate 36, pull the fixed rod 353. The fixed rod 353 drives the fixed slider 354 to move and compress the fixed spring 355, so that the fixed rod 353 disengages from the fixing hole. Then, the square insert block 352 and the fixed seat 351 can be separated, and thus the clamping plate 36 can be removed. This makes it convenient to install the device during use and improves the convenience of use.

[0031] Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is: Specifically, the convenient switch component 5 includes a limit slider 51, a limit slide rod 52, a fixed screw 53, a fastening block 54, a lifting screw 55, a bearing 56, a guide rod 57, and a lifting rotating handle 58. Among them, the limit slider 51 is arranged below one end of the support frame 4. A limit slide rod 52 slides at one end of the limit slider 51. A fixed screw 53 is threadedly connected to one side of the limit slider 51. A fastening block 54 is arranged at one end of the fixed screw 53. A lifting screw 55 is threadedly connected to one end above the support frame 4. A lifting rotating handle 58 is arranged at one end of the lifting screw 55. A bearing 56 is arranged at the connection between the lifting screw 55 and the maintenance cover 6. A guide rod 57 is arranged on one side of the lifting screw 55.

[0033] By adopting the above technical solution, rotating the lifting and rotating handle 58, under the action of the guide rod 57 and the bearing 56, drives the inspection cover 6 to move upward. Then, turn the fixing screw 53 to make the fastening block 54 move and separate from the limit slide rod 52. Thus, through the cooperation of the limit slider 51 and the limit slide rod 52, the inspection cover 6 is moved to separate it from the inspection opening of the inspection seat 1, enabling the device to conveniently open and close the inspection cover 6 during use, and thus facilitating the opening and closing of the inspection opening.

[0034] Specifically, an anti-slip sleeve is sleeved on one end of the fixing screw 53, and support rods are also arranged around the surface of the lifting and rotating handle 58.

[0035] By adopting the above technical solution, the setting of the anti-slip sleeve makes it convenient to rotate the fixing screw 53, and the setting of the support rods makes it convenient to rotate the lifting and rotating handle 58.

[0036] In the use of this embodiment: Rotate the lifting and rotating handle 58. Under the action of the guide rod 57 and the bearing 56, drive the inspection cover 6 to move upward. Then, turn the fixing screw 53 to make the fastening block 54 move and separate from the limit slide rod 52. Thus, through the cooperation of the limit slider 51 and the limit slide rod 52, the inspection cover 6 is moved to separate it from the inspection opening of the inspection seat 1, enabling the device to conveniently open and close the inspection cover 6 during use, and thus facilitating the opening and closing of the inspection opening.

[0037] The working principle and usage process of the present utility model: In the present utility model, during use, the lifting mounting seat 2 is sleeved on the inspection seat 1, and the device is clamped and fixed on the inspection seat 1 through the clamping assembly 3. The inspection cover 6 is driven to open or close through the convenient switch assembly 5. When the clamping assembly 3 is in use, rotate the clamping handle 32. The rotation of the clamping handle 32 drives the bidirectional trapezoidal screw rod 31 to rotate. The rotation of the bidirectional trapezoidal screw rod 31 drives the square slider 33 to move. The movement of the square slider 33 drives the connecting block 34 to move, thereby driving the clamping plate 36 to move and clamping and fixing the device on the inspection seat 1. When it is necessary to replace the corresponding clamping plate 36, pull the fixing rod 353. The fixing rod 353 drives the fixing slider 354 to move and compress the fixing spring 355, so that the fixing rod 353 disengages from the fixing hole. Then, the square insert block 352 can be separated from the fixing seat 351, and thus the clamping plate 36 can be removed, making it convenient to install the device during use and improving the convenience of use. When the convenient switch assembly 5 is in use, rotate the lifting and rotating handle 58. Under the action of the guide rod 57 and the bearing 56, drive the inspection cover 6 to move upward. Then, turn the fixing screw 53 to make the fastening block 54 move and separate from the limit slide rod 52. Thus, through the cooperation of the limit slider 51 and the limit slide rod 52, the inspection cover 6 is moved to separate it from the inspection opening of the inspection seat 1, enabling the device to conveniently open and close the inspection cover 6 during use, and thus facilitating the opening and closing of the inspection opening.
