The handle 7 has a non-slip rubber pad on the outside. The fork 1 can be equipped with hooks, electric shock devices, and other structures as needed, enabling remote control of personnel. This can be used in the capture of knife-wielding criminals.

[0025] A rubber pad 9 is provided on the side of the fork head 1 away from the mounting base 2. The rubber pad 9 is fixedly connected to the fork head 1 via glue and has anti-slip grooves on the side away from the mounting base 2. The fork head 1 is made of steel, and its outer surface is polished. A first spring 16 is provided on the inner side of the fork head 1. The first spring 16 is movably mounted within the cavity within the fork head 1. One end of the first spring 16 is fixedly connected to the telescopic fork frame 10, and the other end has a fixed block fixedly connected to the mounting base 2. The first spring 16 is used to eject the telescopic fork frame 10, so that the telescopic fork frame 10 and the fork head 1 form a fixed ring.

One end of the limit rod 17 has a limit protrusion, which is used to cooperate with the movable limit rod 18 to fix the expansion and storage of the telescopic fork frame 10. The electric push rod 19 is provided with a circuit installation box 5 on the side away from the fork head 1. The circuit installation box 5 is located on the side of the handle 7 close to the fork head 1 and is fixedly connected to the telescopic rod 4. One end of the circuit installation box 5 has a circuit connected to the electric push rod 19. A battery is fixed inside the circuit installation box 5. A control button 6 is fixed to one side of the circuit installation box 5. The control button 6 is used to control the operation of the electric push rod 19. The telescopic fork frame 10 has a limit block on one side close to the first spring 16, and the fork head 1 has a limit protrusion near the opening. The position of the limit protrusion corresponds to the position of the limit block, which is used to limit the extension length of the telescopic fork frame 10 when it pops out.

[0026] The telescopic fork frame 10 has a movable slot 14 on its inner side. A guard plate 12 is provided on the inner side of the circular arc of the telescopic fork frame 10. A movable connection seat 13 is fixed to one side of the guard plate 12. The movable connection seat 13 is movably connected to the movable slot 14 via a movable pin.
