the opposite surfaces of the working end parts of the jaw A and the jaw B are respectively provided with a sawtooth head, and the opposite surfaces of the two sawtooth heads are in sawtooth shapes.

Preferably, the sawteeth on the sawteeth head are matched with the cross-grain knurls of the high-frequency power plug required to be disassembled.

Preferably, the sawtooth head is detachably mounted on the corresponding cheek by a fastener.

Preferably, the sawtooth head is mounted on the corresponding cheek by a screw.

Preferably, the operating ends of the pincer cheek A and the pincer cheek B are handles.

Preferably, the cheek A and the cheek B are made of No. 45 steel hardened and tempered materials.

Preferably, the tooth head is made of T8A material.

Advantageous effects

(1) The dismounting device can be used for conveniently dismounting the high-frequency power plug positioned at the gap between the fire control radar and the airplane body, so that the problem of difficulty in dismounting due to the fact that the high-frequency power plug is dismounted due to narrow space and cannot be touched by hands after the fire control radar is mounted is solved; and the high-frequency power plug and the periphery are prevented from being scratched in the dismounting process.

(2) The saw tooth head is arranged to ensure that the dismounting device can clamp the power plug tightly, and the saw tooth head is connected through the screw, so that friction force can be increased, and meanwhile, the saw tooth head can be conveniently damaged and replaced.

(3) The dismounting device main body is made of No. 45 steel quenched and tempered material, the strength and the hardness are good, the mechanical performance is good, the sawtooth head is made of T8A material, the hardness is guaranteed, meanwhile, the wear resistance is improved, and the service life of the high-frequency power plug dismounting device is guaranteed.

Detailed Description

The invention is described in detail below by way of example with reference to the accompanying drawings.

The embodiment provides a dismounting device for a high-frequency power plug of an airplane, and the high-frequency power plug positioned at a gap between a fire control radar and an airplane body can be dismounted by utilizing the tool, so that the use requirement of the airplane during overhaul is met; and the high-frequency power plug and the periphery are not scratched.

As shown in fig. 1, the detaching device includes: a cheek A1, a cheek B2, a sawtooth head 3 and a connecting pin 4; the pincer cheek A1 and the pincer cheek B2 are made of No. 45 steel hardening and tempering materials, the middle parts of the pincer cheek A1 and the pincer cheek B2 are assembled in an interference fit mode through a connecting pin 4 after crossing, and a scissors type structure is formed and serves as a main body of the dismounting device; one end of the pincer cheek A1 and the pincer cheek B2, which are positioned on the connecting pin 4, is an operating end, and the other end of the connecting pin is a working end, wherein the operating ends of the pincer cheek A1 and the pincer cheek B2 are handles, so that the pincer cheek A1 and the pincer cheek B2 are convenient to hold; the jaw a1 and the jaw B2 are able to rotate about the axis of the connecting pin 4, so that their working ends can be opened or closed when the control operating end is closed or opened.

The length of the working ends of the jaw A1 and the jaw B2 is set according to actual use requirements, and the problem that disassembly and assembly are difficult due to the fact that a fire control radar is installed and a high-frequency power plug is detached in a narrow space and cannot be touched by hands is solved through the working ends of the jaw A1 and the jaw B2.

Saw tooth heads 3 are arranged on the opposite surfaces of the end parts of the working ends of the jaw A1 and the jaw B2, and the saw tooth heads 3 are made of T8A materials; the opposite surfaces of the two sawtooth heads 3 are in a sawtooth shape and are matched with the cross-grain knurls of the high-frequency power plug to be disassembled, so that the high-frequency power plug can be reliably clamped; the sawtooth head 3 is fastened on the corresponding cheek through the cross-slot pan head screw 5, so that the friction force can be increased, and the sawtooth head 3 can be conveniently damaged and replaced.
