Abstract
The utility model provides a wrench with a slot and holes, and belongs to the technical field of aviation manufacturing and maintenance. The apertured wrench includes a handle, a lower corner edge and a sleeve head. When the tool is used, the screw is directly sleeved into the head of the sleeve through the groove at the upper part of the nut to be disassembled, then the head of the sleeve is clamped on the nut to be disassembled, and the tool can be positioned during the disassembly without moving the tool in more space. The utility model has simple and small structure and is particularly suitable for the condition of narrow operation space on an airplane.
Description
Technical Field
The utility model belongs to the technical field of aviation manufacturing and maintenance, and relates to a wrench with a slot.
Background
The aircraft need decompose the bolt of certain position in manufacturing and maintenance's in-process, but because the narrow and small and partly threaded rod overlength of fixation nut of decomposition space, ordinary socket spanner leads to socket inside length b to be less than the threaded rod length c that exceeds the nut (see fig. 1-3) because of spanner structure reason, and the socket can't be fixed with the nut on the screw rod, leads to can't decompose through ordinary socket spanner, can only change ordinary open spanner and continue to decompose, reduces decomposition work efficiency.
Based on the above, the utility model provides a slotted wrench.
Disclosure of utility model
In order to solve the problems in the prior art, the utility model provides the slotted nut with Kong Banshou, which can complete the disassembly work of the nut on the long threaded rod in a narrow space through simple operation.
The technical scheme of the utility model is as follows:
A slotted wrench comprises a handle 1, a lower corner edge 4 and a sleeve head 5; wherein the handle 1, the lower edge 4 of the corner and the sleeve head 5 are of an integrated structure.
The handle 1 is of a bending structure, the bottom of a bending part of the handle is a corner lower edge 4, and an arc-shaped notch is machined on the upper part of the bending part to form a bolt extending hole 2.
The inner surface of the sleeve head 5 is regular hexagon, the front end of the sleeve head is provided with a slot 3, and the symmetry center of the slot 3 is the same as the symmetry axis of the bolt extending hole 2 and is communicated with the bolt extending hole 2; the width of the slot 3 is 8/11-7/11 of the diagonal length of the regular hexagon of the inner surface of the sleeve head 5.
Further, the width of the slot 3 is 7/9 of the diagonal length of the regular hexagon of the inner surface of the sleeve head 5, and the size can better meet the strength requirement of the wrench.
Further, the minimum distance between the edge of the bolt extending hole 2 and the projection of the lower corner edge 4 on the symmetry plane of the wrench is 3/4 of the diameter of the handle.
The utility model has the beneficial effects that:
(1) The utility model has simple and small structure and is particularly suitable for the condition of narrow operation space on an airplane.
(2) When the tool is used, the screw rod can be directly sleeved into the head part of the sleeve through the groove at the upper part of the nut to be disassembled, then the head part of the sleeve is clamped on the nut to be disassembled, and the tool can be positioned during the disassembly without moving the tool in more space.

Detailed Description
The following detailed description of the utility model is further illustrated in conjunction with the examples and the accompanying drawings, but is not intended to limit the utility model.
As shown in fig. 4 to 9, the present embodiment provides a slotted nut Kong Banshou capable of accomplishing the disassembly of the nut on the long threaded rod in a narrow space by a simple operation. The wrench with the holes comprises a handle 1, a corner lower edge 4 and a sleeve head 5, wherein the handle 1, the corner lower edge 4 and the sleeve head 5 are of an integrated structure.
The handle 1 is of a bending structure, the bottom of a bending part of the handle is a corner lower edge 4, and an arc-shaped notch (shown in fig. 7) is machined on the upper part of the bending part to form a bolt extending hole 2. The minimum distance d of the projection of the edge of the bolt-extending hole 2 and the lower corner edge 4 on the symmetry plane of the wrench is 3/4 of the diameter e of the handle (as shown in fig. 5).
The inner surface of the sleeve head 5 is regular hexagon, the front end of the sleeve head is provided with a slot 3, and the symmetry center of the slot 3 is the same as the symmetry axis of the bolt extending hole 2 and is communicated with the bolt extending hole 2; the width of the slot 3 is 7/9 of the diagonal length of the regular hexagon of the inner surface of the sleeve head 5.
In the actual operation, the operator holds the handle 1 of the wrench by hand and then passes the threaded rod through the slot 3 to sleeve the sleeve head 5 over the nut to be disassembled, thereby disassembling the nut. By the design method, the problem that the sleeve head cannot be fixed on the nut to be disassembled due to overlong threaded rods is avoided.
In summary, the above embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
