Embodiment 1

[0031] The purpose of this embodiment is to disclose a hand-held fastening device for nut brackets. The overall device is compact and convenient, and is suitable for operations in narrow spaces.

[0032] A hand-held fastening device for a nut bracket, comprising an outer shell 1 and an inner core 2 . The "L"-shaped shell 1 has a chute on the top, and the tail end of the inner core 2 with a concave structure can be slidably arranged in the chute, and the lower surface of the upper part of the inner core 2 is placed outside the upper surface of the long side of the shell 1. This enables the inner core 2 to slide horizontally relative to the outer shell 1 . The top of the short side of the shell 1 fixes the cover plate 8 by screws 10, restricting the inner core 2 to move horizontally in the chute, and cannot move vertically.

[0033] The disk cam 4 is arranged in the chute of the casing 1, and the disk cam 4 is fixedly connected to the pressure rod 5 through the through shaft 3 ...

Embodiment 2

[0046] In this embodiment, except that the center of the anti-skid handle 15 and the bottom of the front part of the housing 1 are not provided with a weight-reducing hole 16, the other implementation methods, technical solutions and technical effects are the same as those of the first embodiment.

[0047] The hand-held nut bracket fastening device described in this embodiment is compact and convenient as a whole, and can be suitable for working in a narrow space. Moreover, the hand-held nut bracket fastening device described in this embodiment is easy to operate, has a short single working cycle, and significantly improves work efficiency.

Abstract

A handheld nut support buckling device comprises a shell (1) and an inner core (2), a sliding groove is formed in the top of the L-shaped shell (1), the tail end of the inner core (2) of a concave structure is arranged in the sliding groove in a sliding mode, the lower surface of the upper portion of the inner core (2) is arranged outside the upper surface of the long edge of the shell (1), and therefore the inner core (2) can generate relative horizontal sliding. And a cover plate (8) is fixed at the top of the short side of the shell (1) through a screw (10). The machining efficiency can be remarkably improved, the whole device is small and convenient due to the handheld design, and the device is suitable for operation in a narrow space.

Description

technical field [0001] The invention relates to the technical field of aviation parts processing, in particular to a hand-held nut bracket fastening device. Background technique [0002] In the field of aviation technology, a large number of nuts are used. During assembly, the nuts are often required to have a certain amount of activity to ensure that the nuts are in a floating state. At present, the nut bracket is commonly used to fix the nut. The nut is buckled by the bendable claw of the nut bracket. Activity. [0003] However, due to the huge amount of nuts used, manually bending the claws of the nut bracket will greatly reduce the working efficiency, and some working environments with small spaces have certain safety hazards and are not suitable for workers to enter. Contents of the invention [0004] The purpose of the present invention is to disclose a hand-held nut bracket fastening device, the overall device is compact and convenient, and is suitable for operati...
