Description

Anti-nut shedding socket wrench

technical field

The utility model relates to an anti-nut shedding socket wrench.

Background technique

At present, in the maintenance work of equipment in narrow places, it is necessary to disassemble the fixed nut of the equipment. The nut is located on the narrow edge of the equipment, and if you are not careful, it will fall into the relatively deep inside of the equipment, which will bring trouble to the maintenance work.

Utility model content

The purpose of the utility model is to provide an anti-nut shedding socket wrench, which can completely solve the problem that the nut is easy to fall off when disassembling and assembling the narrow edge of the equipment.

In order to achieve the above object, the utility model adopts the following technical scheme: the anti-nut shedding socket wrench, including the connecting head and the socket wrench head, the shape of the inner hole at the lower end of the socket wrench head matches the shape of the nut, and the socket wrench head There is a guide rod hole on the top of the guide rod, and a guide rod is pierced in the guide rod hole. An anti-off positioning device is provided on the guide rod above the socket wrench head. The lower end of the guide rod is provided with a magnetic sucker. A return spring is worn on the guide rod between the suction cups.

A ring magnet is arranged on the end surface of the lower mouth of the socket wrench head.

A square hole for inserting the handle of the wrench is arranged in the connecting head along the axial direction.

The anti-off positioning device is a flat washer and a limit bolt cap arranged on the guide rod.

The distance between the magnetic sucker and the bottom of the socket wrench head is 8-12 mm.

The size of the square hole of the connecting head is larger than the size of the limit bolt cap.

The utility model has the advantages of simple structure and practical function, and can completely solve the problem that the nut is easy to fall off when disassembling and assembling the narrow edge of the equipment. The retractable magnetic suction cup can absorb the nut, and the ring magnet can absorb the gasket, which is very convenient to use, saves time and effort, and greatly improves the removal efficiency.

Detailed ways

Embodiment: As shown in Figures 1-3, the anti-nut drop-off socket wrench includes a connector 8 and a socket wrench head 1. The connector 8 is a cylindrical structure, and the connector 8 is provided along the axial direction for insertion. The square hole 10 of the wrench handle. The shape of the inner hole 4 at the lower end of the socket wrench head 1 matches the shape of the nut, which is a regular hexagonal inner hole 4 in this embodiment. The top of the socket wrench head 1 is provided with a guide rod hole, the guide rod hole is pierced with a guide rod 7, and the guide rod 7 above the socket wrench head 1 is provided with an anti-off positioning device. In this embodiment, the anti-off positioning The device is a flat washer 5 and a limit bolt cap 6 arranged on the guide rod 7 . The lower end of the guide rod 7 is provided with a magnetic sucker 2 , and the guide rod 7 between the top of the socket wrench head 1 and the magnetic sucker 2 is provided with a return spring 3 . A ring magnet 9 is inlaid on the lower end surface of the socket wrench head 1 . The distance between the magnetic sucker 2 and the bottom of the socket wrench head 1 is 8-12 millimeters, which is 10 millimeters in the present embodiment. The size of the square hole of the connector 8 is larger than the size of the limit bolt cap 6, which is convenient for installing the limit bolt cap 6.

In narrow places, when it is necessary to use an anti-nut shedding socket wrench to remove the nut, install the wrench handle on the connector 8, align the socket wrench head 1 with the bolt and press down the telescopic suction cup 2 until the socket wrench head Put the nut on the regular hexagonal inner hole 4 of 1, and then turn the wrench handle to loosen the nut. At this time, the ring magnet 9 absorbs the gasket. When the nut retreats to the level of the bolt rod, the nut is absorbed by the magnetic iron plate 2 , the nut and the magnetic iron plate 2 rotate together to withdraw from the bolt rod, and the nut is absorbed by the magnetic iron plate 2 and will not fall off, which plays a role in preventing the nut from falling off.

When it is necessary to install the nut, install the nut on the socket wrench head 1, the magnetic iron plate 2 absorbs the nut, and then install it, the nut is gradually tightened, the bolt rod is compressed and the magnetic iron plate 2 is disengaged from the nut, and the magnetic iron plate The amount of compression of 2 ensures that the socket wrench head 1 can tighten the nut.
