[0032] In some embodiments, the length of the second disassembly opening 34 of the second disassembly portion 3 is adjusted in the range of 0mm-55mm. Specifically, the adjustment size of the second disassembly opening 34 in the left-right direction is 0mm-55mm, and the second disassembly portion 3 can be used for valves such as ball valves and butterfly valves without operating handles at a switch operation angle of 0°-90°. The opening size of the second disassembly opening 34 is adjusted to the same size as the valve stem, and the valve stem operating force head is clamped on the valve stem to perform force operation on the valve opening and closing.

[0033] In some embodiments, the second disassembly portion 3 includes a mounting seat 31, a first disassembly plate 32, and a second disassembly plate 33.

[0035] In some embodiments, a first anti-skid pad is provided on one side of the first disassembly plate 32 relative to the second disassembly plate 33, and / or a second anti-skid pad is provided on one side of the second disassembly plate 33 relative to the first disassembly plate 32. Specifically, a first anti-skid pad is provided on the right side of the first disassembly plate 32, and a second anti-skid pad is provided on the left side of the second disassembly plate 33. The first anti-skid pad and the second anti-skid pad can be made of rubber or other materials with a high friction coefficient to ensure a good anti-skid effect, so that the friction between the first disassembly plate 32 and the second disassembly plate 33 is increased by the first anti-skid pad and the second anti-skid pad to prevent the second disassembly portion 3 from sliding during use.

[0036] In some embodiments, the telescopic member 1 is a hydraulic rod. Figure 1-2 As shown, the telescopic operating rod has a diameter of 34mm and a length of 460mm. The operating rod has 8 levels of telescopic adjustment. During operation, the length of the telescopic operating rod can be adjusted according to the size of the valve to achieve the effect of changing the operating torque to increase the force of the valve operation. The operating rod is made of a steel pipe, which is hollow inside. The tail end can be inserted into valves such as ball valves and butterfly valves to control the flow of hydraulic oil, thereby controlling the telescopic length of the telescopic member 1.

[0037] In some embodiments, the outer circumference of the telescopic member 1, the outer circumference of the first disassembly portion and the outer circumference of the second disassembly portion are coated with an anti-corrosion coating. Specifically, the outer circumference of the telescopic member 1, the outer circumference of the first disassembly portion and the outer circumference of the second disassembly portion are coated with anti-corrosion paint, thereby extending the service life of the valve booster rod 100.

[0038] In some embodiments, the valve booster rod 100 further includes a lighting component (not shown in the figure), which is disposed on the telescopic component 1 and is disposed in the direction adjacent to the first disassembly portion, so that the lighting component can illuminate the first disassembly portion and the second disassembly portion. Specifically, the lighting component can be an LED lighting lamp, which is disposed on the cylinder body of the telescopic component 1 and illuminates to the left, thereby ensuring that light can directly illuminate the operating area and illuminate the first disassembly portion and the second disassembly portion.

[0039] In some embodiments, the outer circumference of the telescopic member 1 is provided with an anti-skid cover (not shown in the figure). Specifically, the anti-skid cover can be made of a material with a high friction coefficient, such as rubber, silicone or other elastic materials, and the anti-skid cover is usually designed to be tubular or annular, and is sleeved on the outer circumference of the telescopic member 1. Therefore, the anti-skid cover not only prevents the outer surface of the telescopic member 1 from being worn or scratched, thereby extending the service life of the telescopic member 1, but also enables the valve booster rod 100 to adapt to different working environments, especially in humid or sweaty conditions, and still maintains a good anti-skid effect, thereby ensuring the working efficiency of the valve booster rod 100.
