The motor 3 adopts a low-speed direct-current torque motor, the direct-current motor is provided with locked rotor protection, and when the device drives the valve core to rotate to a full-open or full-close position, the direct-current motor stops rotating due to the locked rotor protection. A corresponding mobile power supply is arranged at a proper position of the lower part of the telescopic hollow handle 1 and supplies power to the motor 3.

As shown in fig. 3-5, a valve core clamping die 5 is arranged on the mounting plate 4, and the valve core clamping die 5 comprises a fixed lower die 5-1 and a movable upper die 5-2. The fixed lower die 5-1 is fixed on the mounting plate 4, the first guide rod 5-3 is fixed at a proper position on the back of the movable upper die 5-2, the first guide rod 5-3 is a T-shaped rod, the first guide rod 5-3 is slidably arranged on the first limiting groove 5-4 of the mounting plate 4, and the first limiting groove 5-4 is vertically arranged. The movable upper die 5-2 can vertically slide up and down and cannot be separated from the mounting plate 4 by arranging the first guide rod 5-3 and the first limit groove 5-4.

A clamping groove 5-5 matched with the valve core is arranged in the middle of one end of the fixed lower die 5-1 opposite to the movable upper die 5-2. Through holes are arranged on the left and the right of the fixed lower die 5-1, a first positioning bulge is arranged on the corresponding movable upper die 5-2, and the first positioning bulge is connected with the bottom surface of the through hole of the fixed lower die 5-1 through a first spring 5-6. When the movable upper die 5-2 moves downwards and is closed with the fixed lower die 5-1, the first positioning bulge is just matched and clamped with the through hole of the fixed lower die 5-1, and the first spring 5-6 is compressed. Therefore, the movable upper die 5-2 can be limited to move transversely and in a staggered way relative to the fixed lower die 5-1, and matching is guaranteed.

As shown in fig. 1-2 and 7, in order to close the fixed lower die 5-1 and the movable upper die 5-2, a locking mechanism 6 is arranged on the housing 7, the locking mechanism 6 comprises a fixed lower positioning ring 6-1 and a movable upper pressing ring 6-2, wherein the fixed lower positioning ring 6-1 is fixed on the housing 7, the left back and the right back of the movable upper pressing ring 6-2 are fixed with second guide rods 6-3, the second guide rods 6-3 are T-shaped rods, the second guide rods 6-3 are slidably arranged on second limiting grooves 6-4 of the housing 7, and the second limiting grooves 6-4 are vertically arranged. The movable upper die 5-2 can vertically slide up and down and cannot be separated from the shell 7 by arranging the second guide rod 6-3 and the first limit groove 5-4.

In addition, through holes are formed in the left and right sides of the fixed lower positioning ring 6-1, first positioning protrusions are arranged on the corresponding movable upper pressing rings 6-2, and the first positioning protrusions are connected with the bottom surface of the hole of the fixed lower positioning ring 6-1 through second springs 6-5. When the movable upper press ring 6-2 moves downwards and is closed with the fixed lower positioning ring 6-1, the first positioning bulge is just matched and clamped with the through hole of the fixed lower positioning ring 6-1, and the second spring 6-5 is compressed. Thus, the transverse displacement movement of the movable upper press ring 6-2 relative to the fixed lower positioning ring 6-1 can be limited.

A hanging ring 8 is hinged on the movable upper pressing ring 6-2, the hanging ring 8 is connected with a pull rope 6-6, and the movable upper pressing ring 6-2 can move downwards to be closed with the fixed lower positioning ring 6-1 by pulling the pull rope 6-6.

In addition, in order to reduce the friction between the valve core clamping die 5 and the locking mechanism 6, rotatable rollers 5-7 are circumferentially arranged on the side walls of the fixed lower die 5-1 and the movable upper die 5-2. When the locking mechanism 6 presses the valve core clamping die 5, the locking mechanism 6 and the valve core clamping die 5 form rolling friction through rollers 5-7.

The working principle and the process are as follows: firstly, the length of the telescopic hollow handle 1 is adjusted according to the height of the valve core, and then the telescopic hollow handle 1 is manually operated, so that the valve core is inserted into the clamping groove 5-5 of the valve core clamping die 5. And pulling the pull rope 6-6 to enable the movable upper press ring 6-2 to move downwards and to be closed with the fixed lower positioning ring 6-1, and at the moment, the movable upper die 5-2 is pressed downwards by the movable upper press ring 6-2 and is also closed with the fixed lower die 5-1 to clamp the valve core tightly. And winding the tensioned pull rope 6-6 on a fixed column 9 at the lower end to be fixed. And then, starting the switch of the motor 3, wherein the motor 3 drives the mounting plate 4 and the valve core clamping die 5 to rotate, so that the valve is switched. After the operation is finished, the pull rope 6-6 is loosened, the movable upper die 5-2 and the movable upper press ring 6-2 are reset under the action of the first spring 5-6 and the second spring 6-5, and the device is taken away.
