[0002] At present, most material mounting is in the form of automatic mounting, such as a nail gun, a glue gun, a welding gun and the like, but the installation of materials requiring screws, such as most threaded fasteners, still needs to manually bring the bolt into one or two teeth, and then install them one by one by using a power tool or a wrench sleeve, so that the installation efficiency is not high, and in special environments such as high-altitude operation, or only one hand is available, the installation of fasteners becomes dangerous or cumbersome.

[0003] Publication 1, Chinese patent (114074388A) nut mounting mechanism, comprising a frame body and a nut driving part; the frame body is provided with a nut conveying channel, and the nut conveying channel sequentially has a first position, a second position and a third position which are not arranged in the same line; the nut at the second position can fall into the third position; the frame body is provided with a misalignment plate for pushing the nut from the first position to the second position; the nut driving part comprises a driving shaft, and one side of the driving shaft facing the third position is provided with a friction surface. The nut conveying channel and the misalignment plate are arranged to periodically send the nut to the output end of the driving shaft, and the nut conveying channel fully utilizes the gravity of the nut to realize position movement.

[0004] The nut mounting mechanism of publication 1 realizes position movement by using the gravity of the nut itself, and the angle is single, so that multi-angle installation cannot be performed.

[0005] Publication 2, Chinese patent (108213932A) nut mounting mechanism and nut mounting device, the nut mounting mechanism comprises a torque gun and an automatic cap mounting structure, the automatic cap mounting structure comprises a base, the base is formed with a through hole, a cap channel intersecting and communicating with the through hole and an inlet cap channel communicating with the cap channel, the inlet cap channel is connected with a nut supply unit, the cap channel is provided with a positioning and clamping unit for pushing and clamping the nut at the intersection of the through hole, the gun head of the torque gun is inserted into the through hole, and the torque gun is connected with a feeding unit for driving the gun head to feed along the gun barrel in the axial direction.

[0006] The nut mounting mechanism and the nut mounting device of publication 2 have a complex structure, the torque gun occupies a large space of the whole device, the operation is complex, and the device cannot be applied to special environments such as high-altitude operation. SUMMARY

[0007] The technical problem to be solved by the application is to overcome the shortcomings of the prior art, provide a handheld nut mounting mechanism, and realize automatic loading of nuts, nut installation at any angle and nut installation in special environments.

[0008] The hand-held nut mounting mechanism comprises a cartridge device and a driving device, and the cartridge device is arranged on one side of the driving device;

[0017] The limiting bridge is arranged between the first rotating device and the third rotating device, and a limiting groove is arranged on one side of the limiting bridge corresponding to the push table. The push table pushes the nut into the middle part of the limiting bridge from the limiting groove, so that the nut cannot be deviated, reversed or dropped into the rotating device no matter the mechanism is at any angle, and full-angle adaptation is realized.

[0018] The inner wall of the sleeve is matched with the shape of the nut. The rotation of the nut in the sleeve is prevented, and the installation of the nut is affected.

[0019] The middle part of the first rotating device, the third rotating device and the limiting bridge is provided with a sliding channel matched with the magnet push rod. The sliding channel is a moving channel of the nut, and the nut moves downward in the sliding channel and accurately enters the rotating drum, so that the installation angle is ensured.
