Referring to fig. 1-5, in the present embodiment, an electric nailing gun with a safety device includes a gun body 1, a handle 2 and a gun barrel 3, the gun barrel 3 is disposed on the gun body 1, the gun barrel 3 is horizontally disposed, a linkage mechanism 6 is disposed in the gun body 1, the linkage mechanism 6 can eject nails from the gun barrel 3 at a high speed, the handle 2 is connected with the gun body 1 for a worker to hold, the gun barrel 3 is further provided with the safety device, the safety device includes a trigger 4 and a trigger triggering assembly 5, the trigger 4 is hinged to the gun body 1, and the trigger 4 can control the on-off of the linkage mechanism 6 under the action of the trigger triggering assembly 5, the trigger triggering assembly 5 is slidably disposed at a nozzle of the gun barrel 3, and when an external force is applied, the trigger triggering assembly 5 can move along the axis of the gun barrel 3 and trigger the trigger 4.

The trigger assembly 5 comprises a trigger sleeve 51, the trigger sleeve 51 is slidably disposed on the gun body 1, the trigger sleeve 51 and the gun barrel 3 are located on the same axis, the trigger sleeve 51 is further connected with a sliding block 52, the sliding block 52 is exposed out of the gun body 1, and is matched with a sliding rail 53 disposed on the gun body 1 and can move along the sliding rail 53, and a trigger block 54 is further disposed on one side of the sliding block 52. The trigger sleeve 51, the sliding block 52 and the sliding rail 53 are arranged to realize sliding along the direction of the gun barrel 3, and then the trigger 4 is triggered by the trigger triggering block 54 to control the on-off of the linkage mechanism 6.

The trigger assembly 5 further comprises a return spring 55, the return spring 55 is arranged between the sliding block 52 and the gun body 1, the return spring 55 is sleeved in the sliding rail 53, and two ends of the return spring 55 respectively abut against the sliding block 52 and the gun body 1. Reset spring 55's setting when guaranteeing that external force disappears, trigger subassembly 5 can be timely reset, and then make trigger 4 close link gear 6, guarantee and realize the safe handling of electronic nailing gun, and reset spring 55's number suitably adds as required simultaneously.

Referring to fig. 5, a rectangular through hole 541 is formed in the trigger block 54, and the trigger block 54 is slidably connected to the slide block 52 through the rectangular through hole 541, while a buffer spring 56 is provided between the slide block 52 and the trigger block 54, and a guide post 57 is provided in the buffer spring 56. The trigger block 54 and the sliding block 52 can be ensured to move stably relative to each other and can only slide along the rectangular through hole 541, the design of the buffer spring 56 can prevent the trigger block 54 from being in hard contact with the trigger 4, and the service life of the trigger 4 can be prolonged.

The free end of the trigger sleeve 51 is also provided with a stop collar 511. The design of the limiting ring 511 ensures that the running distance of the trigger sleeve 51 is consistent, and accidents are not easy to happen when the trigger force is large in time. The inside dimension of the trigger sleeve 51 is not smaller than the inside dimension of the barrel 3. The nail flying out of the gun barrel 3 can be ensured to fly out smoothly.

A torsion spring 41 is arranged at the position where the trigger 4 is hinged with the gun body 1. The design of the torsion spring 41 can ensure that the trigger 4 is disconnected in time when the external force disappears, and the safety of a user is ensured.

The electric nailing gun with the safety protection device has the advantages that the safety protection device is creatively arranged at the position of the muzzle, only when the trigger triggers the assembly 5 to move, the trigger 4 can trigger, the nail can be ejected, the use safety is guaranteed, and the operation difficulty can not be increased.

The description of the reference numbers in the figures, regarding the torsion spring 41, the return spring 55, the buffer spring 56 and the guide post 57, are not shown in the figures, but the position of the torsion spring 41 is set in the middle hinge hole of the trigger 4 shown in fig. 4, and the two ends of the torsion spring 41 respectively abut against the gun body 1 and the trigger 4; the position of the return spring 55 is set at the position of the mark 53 shown in fig. 2; the buffer spring 56 is disposed in the position shown in fig. 5, with the left end of the buffer spring 56 abutting the slide block 52 and the right end abutting the trigger block 54, and with the guide post 57 inserted in the buffer spring 56.

The basic process of the device during use is that a worker holds a nailing gun, the two hands hold the handle 2 and the gun body 1 simultaneously, the part of the muzzle faces the nailing position, then the end part of the nailing gun is forced to contact with the nailing position, the trigger sleeve 51 of the trigger assembly 5 can contract inwards at the moment (but due to the arrangement of the limit ring 511, the retraction distance of the trigger sleeve 51 is certain), the sliding block 52 also contracts inwards at the moment, the sliding block 52 drives the trigger block 54 to move, the trigger 4 can be triggered at the moment, the trigger 4 enables the nailing gun to work, when the muzzle is separated from the nailing part, under the action of the reset spring 55, the sliding block 52 drives the trigger block 54 to separate from the trigger 4, meanwhile, the trigger 4 is rapidly reset under the action of the torsion spring 41, and the nailing gun does not work at the moment. In particular, the design of the buffer spring 56 provides a buffer force when the slide block 52 drives the trigger block 54 to trigger the trigger 4, so as to prevent the trigger block 54 from rigidly colliding with the trigger 4 and further damaging the service time of the trigger 4.

Above-mentioned safety device's design makes the muzzle support to lean on the time, just can retract by hard pressing to trigger the work of nailing gun, avoided the muzzle to the problem that the people can accidentally injure, improved holistic security, also can reduce the complexity of operation.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
