[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a valve switch extension rod, including a T-shaped wrench 1, an extension rod body 2 and a slot 9.

[0023] The T-shaped wrench 1 includes: a horizontal bar 101, a vertical bar 102 and an anti-slip sleeve 103. Two sets of anti-slip sleeves 103 are fixedly installed at both ends of the surface of the horizontal bar 101. One end of the vertical bar 102 is fixedly installed on the surface of the horizontal bar 101, and one end of the vertical bar 102 is located between the two sets of anti-slip sleeves 103. A disassembly and assembly component for disassembling and assembling the extension rod body 2 is provided between the other end of the vertical bar 102 and the upper end of the extension rod body 2.

[0024] Among them, there are several extension rod bodies 2 in the device, and the upper end of each extension rod body 2 can be fixedly installed on the bottom end of the vertical rod 102 of the T-shaped wrench 1 through disassembly and assembly components. At the same time, the bottom of each extension rod body 2 is provided with a slot 9 of different shapes, and the slots 9 of different shapes are respectively adapted to different types of valve switches.

[0025] Specifically, through the coordinated use of the T-shaped wrench 1, the extension rod body 2, the slot 9 and the disassembly and assembly components, when opening and closing the square valve switch, first select the slot 9 at the bottom of the extension rod body 2 to be square, and then use the disassembly and assembly components to fix the upper end of the extension rod body 2 on the vertical rod 102 of the T-shaped wrench 1; when opening and closing the long strip valve switch, first remove the extension rod body 2 with the square slot 9 at the lower end from the vertical rod 102 of the T-shaped wrench 1, and then select the slot 9 at the bottom of the extension rod body 2 to be rectangular, and then use the disassembly and assembly components to fix one end of the extension rod body 2 on the vertical rod 102 of the T-shaped wrench 1, so that it is convenient for operators to open and close different types of gas pipeline valve switches in the gate well, which greatly improves the portability of the device and reduces the space occupied by the device. It has a simple structure, is easy to use, and increases the practicality of the device.

[0026] The disassembly and assembly components include: a mounting block 3, a mounting hole 4, a mounting slot 5, a fixing hole 6, a mounting rod 7 and a fixing mechanism 8. The mounting block 3 is fixedly installed on the top of the extension rod body 2. A mounting hole 4 is opened through one side of the mounting block 3. The mounting slot 5 is opened at the bottom of the vertical rod 102. The interior of the mounting slot 5 is adapted to the surface of the mounting block 3, and the mounting block 3 is slidably connected to the inner wall of the mounting slot 5. The fixing hole 6 is opened through the lower end of the surface of the vertical rod 102. The fixing hole 6 is communicated with the interior of the mounting slot 5, and the fixing hole 6 and the mounting hole 4 are correspondingly arranged.

[0027] The interior of the mounting hole 4 and the interior of the fixing hole 6 are adapted to be connected with a mounting rod 7, one end of the mounting rod 7 passes through the interior of the mounting hole 4 and the interior of the fixing hole 6 and is connected with a fixing mechanism 8, and the mounting rod 7 is fixed to the interior of the mounting hole 4 and the interior of the fixing hole 6 through the fixing mechanism 8.

[0028] Specifically, through the coordinated use of the mounting block 3, the mounting hole 4, the mounting slot 5, the fixing hole 6, the mounting rod 7 and the fixing mechanism 8, the mounting block 3 is first aligned with the mounting slot 5, and then the mounting block 3 is slid into the interior of the mounting slot 5, so that the mounting hole 4 is aligned with the fixing hole 6, and then one end of the mounting rod 7 is passed through the interior of the fixing hole 6 and the interior of the mounting hole 4 and then appears on one side of the vertical rod 102, and then the fixing mechanism 8 is used to limit the mounting rod 7, so that the mounting rod 7 can be limited and fixed inside the mounting hole 4 and the interior of the fixing hole 6, and then the mounting block 3 can be fixed to the inner cavity of the mounting slot 5. At the same time, the mounting block 3 is rectangular, which can make it easy for the user to control the T-shaped wrench 1 to rotate, so that the extension rod body 2 rotates with it, so as to facilitate the opening and closing of the gas pipeline valve.

[0029] The fixing mechanism 8 includes: a fixing block 801, a fixing rod 802, a limiting block 803, a torsion block 804 and a limiting slot 805. The fixing block 801 is fixedly installed on the surface of the vertical rod 102. The upper end of the fixing block 801 is rotatably connected to the fixing rod 802, and the lower end of the fixing block 801 is slidably connected to the limiting block 803. The surface of one end of the fixing rod 802 is connected to the internal thread of the limiting block 803, and the other end of the fixing rod 802 is fixedly installed with the torsion block 804. The limiting slot 805 is opened through one end of the mounting rod 7, and the interior of the limiting slot 805 is adapted to the surface of one end of the limiting block 803, and one end of the limiting block 803 is inserted into the inner cavity of the limiting slot 805.

[0030] Specifically, by cooperating with the fixing block 801, the fixing rod 802, the limiting block 803, the twisting block 804 and the limiting slot 805, the twisting block 804 is used to control the rotation of the fixing rod 802, so that the fixing rod 802 slides with the limiting block 803 inside the fixing block 801, thereby controlling the limiting block 803 to enter or exit the limiting slot 805. When the limiting block 803 enters the limiting slot 805, one end of the mounting rod 7 can be limited so that the mounting rod 7 stays inside the mounting hole 4 and the fixing hole 6. When the limiting block 803 exits the limiting slot 805, the mounting rod 7 can be easily removed from the mounting hole 4 and the fixing hole 6, so that the mounting block 3 can slide out from the inside of the mounting slot 5, making it convenient to replace the extension rod body 2.
