[0039] Accommodation space 2 has recess 201 and limit hole 202, and accommodation space 2 is arranged in the inside of fixed part 1, recess 201 is arranged in the right part center position of accommodation space 2, and limit hole 202 is arranged in the lower part of accommodation space 2;

[0040] Clamping hole 3 is symmetrically arranged on the outer surface of both sides of fixed part 1;

[0041] Fixed assembly 4 is arranged in the inside of clamping hole 3, and fixed assembly 4 includes:

[0042] Clamping piece 5 has bottom end 501 and top end 502, clamping piece 5 passes through clamping hole 3, the top end 502 of clamping piece 5 is located on the same vertical line with clamping hole 3, and the bottom end 501 of clamping piece 5 is inserted into the inside of recess 201;

[0043] Mounting block 6 is fixed on the inner wall of the upper end and the lower end of accommodation space 2;

[0044] Mounting rack 7 has a sliding slot, and the sliding slot is arranged at the center position of mounting rack 7;

[0045] Slide rod 8 is movably connected in the inside of the sliding slot, one side of slide rod 8 is welded on one side of mounting rack 7, and the other side of slide rod 8 is welded on one side of clamping piece 5;

[0046] Spring 9 has first end 901 and second end 902, first end 901 is welded on one side of mounting block 6 opposite to slide rod 8, and second end 902 is welded on one side of slide rod 8 opposite to mounting block 6;

[0047] Limiting plate 10 is welded on the bottom surface and top end 502, and top end 502 is welded on the center position of the bottom surface of limiting plate 10, wherein the bottom surface of limiting plate 10 is attached to one side of fixed part 1;

[0048] Buckling piece 11 is arranged at the bottom of fixed part 1;

[0049] Limiting block 13 has a bushing 131, and limiting block 13 is arranged at the top of base 14, and bushing 131 is arranged in the inside of limiting block 13.

[0050] The limiting block 13 and the limiting hole 202 are arranged on the same vertical line.

[0051] Specifically, such as Figures 1-6 When the locking cam 5 is unlocked, the locking cam 5 is unlocked, and the locking cam 5 is unlocked, so that the user can easily pull the locking cam 5. The locking cam 5 is locked in the locking cam 5, and the locking cam 5 is locked in the locking cam 5.

[0052] The fixing components 4 are arranged in two groups, the clamping member 5 is arranged in a rectangular shape, and the clamping hole 3, the top end 502, the bottom end 501 and the groove 201 have the same size.

[0053] Specifically, such as Figures 1-6 As shown, the two sets of fixing components 4 can provide stronger support and stability for the connection between the fixing part 1 and the base 14, ensuring that the entire structure is not easily shaken or deformed when subjected to external force. Since the card hole 3, the top end 502, the bottom end 501 and the groove 201 have the same size, fast and accurate installation and disassembly can be achieved.

[0054] The slide bar 8 is welded to the left side of the clamp 5 .

[0055] The mounting block 6 and the slide bar 8 are arranged in parallel, the spring 9 and the slide bar 8 are arranged perpendicularly, and the spring 9 and the mounting block 6 are arranged perpendicularly.

[0056] Specifically, such as Figures 1-6 As shown, the parallel arrangement of the mounting block 6 and the slide bar 8 ensures that the slide bar 8 maintains linear motion during movement, reducing deviation and shaking, thereby improving the stability of the entire structure. The vertical arrangement of the spring 9 ensures that the force applied to the spring 9 is uniform when the slide bar 8 moves and compresses the spring 9. This helps to extend the service life of the spring 9 and reduce problems caused by uneven force.

[0057] The limiting holes 202 are arranged in two groups, and the limiting blocks 13 are arranged in two groups. The limiting holes 202 have the same size as the limiting blocks 13 . The insertion holes 131 are arranged in the center of the limiting blocks 13 , and the size of the insertion holes 131 is the same as that of the card 5 .

[0058] Specifically, as shown in Figures 1-6 The two sets of limiting holes 202 and limiting blocks 13 can provide stronger stability and ensure that the structure is not easily displaced or deformed when subjected to external forces. Because the limiting holes 202 and limiting blocks 13 are the same size, precise positioning can be achieved, which helps to ensure the relative position between the limiting holes 202 and limiting blocks 13 is accurate, thereby improving the accuracy and reliability of the connection between the fixing part 1 and the limiting block 13. The size of the insertion hole 131 is the same as that of the clamping piece 5, so that the clamping piece 5 can be easily inserted and removed, improving work efficiency.

[0059] The connecting rod 12 is welded on one side of the limiting plate 10, and the pull ring 16 is welded and fixed on the outer surface of the connecting rod 12.

[0060] Specifically, as shown in Figures 1-6 Welding can ensure stable and reliable connection between the connecting rod 12 and the limiting plate 10, and is not prone to loosening or falling off. The provision of the pull ring 16 allows the operator to conveniently operate the connecting rod 12 by pulling the pull ring 16, thereby achieving portable extraction of the limiting plate 10 and the clamping piece 5. This improves the ease of use and operational efficiency of the fixing assembly.

[0061] The pull ring 16 is annularly arranged.

[0062] Specifically, as shown in Figures 1-6 The annular arrangement allows the pull ring 16 to have a larger contact area, making it easier for the operator's hand to hold the pull ring 16 and thus apply force more easily. This arrangement improves the convenience and comfort of operation.

[0063] Instructions: When the regulating valve 15 needs to be disassembled, hold the pull ring 16 and pull it to both sides of the fixing part 1. The pull ring 16 will move the limiting plate 10 and the clamping piece 5 outward together until the clamping piece 5 is pulled out to the limiting hole. The fixing part 1 and the base 14 will be released from the limiting and fixing, and then the fixing part 1 can be removed, achieving portable disassembly of the regulating valve 15. This effectively solves the technical problem in the prior art that the operator needs to carry tools to disassemble the valve positioner, which is not conducive to the operator to disassemble it, thereby significantly reducing the steps and tools required during disassembly, allowing the operator to quickly and more conveniently disassemble, improving disassembly efficiency.

[0064] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments.
