Since the surface of the handle 8 is annularly arrayed with a plurality of anti-skid grooves, the firefighter is not easy to slip off the handle 8 when holding the handle 8 to operate, which improves the stability and safety of the operation.

[0047] Embodiment 3

[0048] As Figures 6-10As shown, on the basis of embodiment 2, the utility model provides a technical scheme: preferably, connecting rod assembly 4 includes drive assembly 41 and connecting block four 44, drive assembly 41 is fixedly connected with connecting pipe 42 symmetrically, the inner chamber of connecting pipe 42 is slidably connected with butt joint lever 43, the side of connecting block three 3 close to drive assembly 41 is fixedly connected with adjacent butt joint lever 43, the side of connecting block four 44 close to mounting rod 5 is fixedly connected with adjacent connecting block one 21, the side of connecting block four 44 away from connecting block one 21 is fixedly connected with adjacent butt joint lever 43, drive assembly 41 includes shell two 411, gear one 412 and gear two 413, shell two 411 is rotatably connected with gear one 412, gear two 413 is meshingly connected with adjacent gear one 412, gear two 413 middle part is fixedly connected with bidirectional screw rod 414, bidirectional screw rod 414 is rotatably connected with shell two 411, bidirectional screw rod 414 is rotatably connected with two connecting pipes 42, bidirectional screw rod 414 is threadedly connected with two butt joint levers 43, butt joint lever 43 is fixedly connected with sliding block 431 symmetrically, the inner chamber of connecting pipe 42 is symmetrically provided with sliding slot one 421, butt joint lever 43 is slidably connected with the inner chamber of adjacent sliding slot one 421.

[0049] In the embodiment, when the length of the device needs to be extended, the connecting rod assembly 4 needs to be connected with the device, so that the length of the device can be extended. When splicing, the mounting rod 5 is separated from the sleeve assembly 2, then the clamping block 9 fixedly connected with the connecting block three 3 is slidably pushed into the inner chamber of the connecting block one 21 fixedly connected with the valve body 1, then the above steps are repeated, the connecting rod assembly 4 is connected with the valve body 1, then the clamping block 9 fixedly connected with the mounting rod 5 is slidably pushed into the inner chamber of the connecting block one 21 fixedly connected with the connecting block four 44, then the above steps are repeated, the connecting rod assembly 4 is connected with the mounting rod 5.

[0050] After splicing, when the length of the device needs to be further extended, the firefighter can rotate the gear one 412 by operation, then drive the gear one 412 to meshingly move adjacent gear two 413, so that the gear two 413 can be rotated. Since the bidirectional screw rod 414 is fixedly connected with the gear two 413, when the gear two 413 rotates, the bidirectional screw rod 414 will rotate together. Since the bidirectional screw rod 414 is threadedly connected with the butt joint lever 43, when the bidirectional screw rod 414 rotates, the butt joint lever 43 can slide in the inner chamber of the connecting pipe 42, so that the distance between the two butt joint levers 43 can be adjusted, then the distance between the valve body 1 and the mounting rod 5 can be adjusted, so that the length of the device can be further extended. When the butt joint lever 43 slides in the inner chamber of the connecting pipe 42, the sliding block 431 will slide in the inner chamber of the sliding slot one 421, so that the position of the butt joint lever 43 in the inner chamber of the connecting pipe 42 can be limited, preventing the butt joint lever 43 from rotating in the inner chamber of the connecting pipe 42.

[0051] The working principle of this portable electric valve opener for fire protection is explained in detail below.

[0052] like Figures 1-13 As shown, when the device needs to be operated, the devices need to be assembled together to facilitate operation. First, the locking block 9 connected to the mounting rod 5 is slid into the inner cavity of the connecting block 21, which is fixedly connected to the valve body 1. When the locking block 9 is slid into the inner cavity of the connecting block 21, the locking block 9 will apply a force to the protrusion 242, causing the protrusion 242 to move towards the indicator block 244. Then, it will cause the spring 243 to retract, and at the same time, it will cause the sliding rod 245 and the indicator block 244 to move together. Then, it will cause the indicator block 244 to move away from the outer shell 241. When the protrusion 242 contacts the inner cavity of the adjacent positioning groove 91, the spring 243 will extend under its own elastic force, and then push the protrusion 242 in the inner cavity of the outer shell 241 towards the locking block 9, and then drive the sliding rod 245 and the indicator block... 244 moves together toward the direction of the locking block 9. Then, with the cooperation of the protrusion 242 and the positioning groove 91, the position of the locking block 9 in the inner cavity of the connecting block 1 21 can be positioned. Then, the position of the locking block 9 in the inner cavity of the connecting block 1 21 can be fixed by operating the bolt 1 23. Then, by rotating the nut on the bolt 2 721, the position restriction of the bolt 2 721 in the inner cavity of the slide groove 2 711 can be released. Then, by rotating the docking block 2 72, the handle 8 is rotated and unfolded. Then, by rotating the nut on the bolt 2 721, the position of the bolt 2 721 in the inner cavity of the slide groove 2 711 can be locked. Then, the staff can operate the device by holding the handle 8. Since the surface of the handle 8 has several anti-slip grooves arranged in a ring array, the hands of the firefighters are not easy to slip off the handle 8 when holding it to perform various operations, which improves the stability and safety of the operation.

[0053] When it is necessary to extend the length of the device, the connecting rod assembly 4 needs to be connected to the device to extend the length of the device. When splicing, first separate the mounting rod 5 from the sleeve assembly 2, then slide the locking block 9, which is fixedly connected to the connecting block 3 3, into the inner cavity of the connecting block 1 21, which is fixedly connected to the valve opener body 1. Then repeat the above steps to connect the connecting rod assembly 4 to the valve opener body 1. Then slide the locking block 9, which is fixedly connected to the mounting rod 5, into the inner cavity of the connecting block 1 21, which is fixedly connected to the connecting block 4 44. Then repeat the above steps to connect the connecting rod assembly 4 to the mounting rod 5.

[0054] After the splicing is completed, when it is needed to further lengthen the length of the device, the firefighter can rotate the gear one 412 by operation, and then drive the gear one 412 to mesh with the adjacent gear two 413, so as to drive the gear two 413 to rotate. Since the bidirectional threaded rod 414 is fixedly connected with the gear two 413, when the gear two 413 rotates, the bidirectional threaded rod 414 will rotate together. Since the bidirectional threaded rod 414 is threadedly connected with the butt joint rod 43, when the bidirectional threaded rod 414 rotates, the butt joint rod 43 can slide in the inner cavity of the connecting pipe 42, so that the distance between the two butt joint rods 43 can be adjusted, and then the distance between the valve body 1 and the mounting rod 5 can be adjusted, so that the length of the device can be further lengthened. When the butt joint rod 43 slides in the inner cavity of the connecting pipe 42, the sliding block 431 will slide in the inner cavity of the sliding groove one 421, so that the position of the butt joint rod 43 in the inner cavity of the connecting pipe 42 can be limited, and the rotation of the butt joint rod 43 in the inner cavity of the connecting pipe 42 is prevented.

[0055] The above has made a detailed description of the utility model in general, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the utility model are within the protection scope of the utility model.
