Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

In the embodiment shown in fig. 1 to 5, a simplified electric hammer tacker is provided, which comprises an electric hammer tacker main body 1, a spring 2 and a nail tail fixing ring 3, wherein one end of the spring 2 is connected to the nail tail fixing ring 3, and the other end of the spring is connected to the electric hammer tacker main body 1 through a detachable structure.

In the embodiment, the detachable structure comprises a spring fixing groove 11 arranged on the peripheral wall of the electric hammer tacker main body 1; the spring 2 has a tapered end portion 21 which is fitted into the spring fixing groove 11.

By adopting the spring 2 with the conical end part 21 and fixing the spring 2 on the spring fixing groove 11 on the electric hammer tacker main body 1, the spring can be normally used without sliding, and the nail tail fixing ring 3 connected with the spring 2 is prevented from falling. When carrying out electric hammer nailing ware main part 1 and maintaining, only need spring 2 from 11 position dismantlements of spring fixed groove can, easy operation can used repeatedly, economic benefits is higher.

In an alternative embodiment of this embodiment, the other end of the spring 2 is connected to the nail tail fixing ring 3 in an interference fit manner. Also realized dismantling between nail tail retainer plate 3 and the spring 2 like this, make things convenient for the two to be removable after damaging, further reduced use cost.

In an optional implementation manner of this embodiment, the spring 2 is a conical spring, and the size of one end of the conical spring, which is connected with the spring fixing groove 11 in a matching manner, is smaller than that of the other end of the conical spring, which is connected with the nail tail fixing ring 3.

In an optional implementation manner of this embodiment, the electric hammer tacker body 1 is further provided with a retrogressive scale 12 of the tail fixing ring, and the retrogressive scale is located in an axial telescopic stroke interval of the spring 2. The design of nail tail retainer plate retrograde scale 12 can just can see out the distance of marcing that 5 nails were driven into of nail tail retainer plate 3 directly perceivedly at any time under the prerequisite of not destroying electric hammer nail ware main part 1 and nail tail retainer plate 3, has avoided electric hammer nail ware still to continue to drive into and the panel face that causes damages after 5 nails are driven into the panel face into of nail.

In an alternative embodiment of the present embodiment, the retrograded scale 12 of the nail-tail retainer ring is formed by laser engraving or stamping. In the two modes, the stamping has higher production efficiency in mass production, and the laser engraving has advantages in medium and small mass production and high scale precision.

In an alternative embodiment of this embodiment, the hammer tacker body 1 may be specifically configured to include a tacker central body and a wear structure 13 attached to its top end face. The presence of the wear-resistant structure 13 makes it possible to reduce the deformation of the hammer tacker body 1 under stress. Further preferably, the wear-resistant structure 13 is made of hard alloy sheets, so that the hardness meets the use requirement, and meanwhile, the wear-resistant structure is low in price and maximized in economic benefit.

The production and use processes are as follows:

firstly, production: firstly, producing a central body of the nailing device, and simultaneously opening a spring fixing slot; then the central body of the nail device is sent to a laser engraving machine to engrave the retrogressive scale 12 of the nail tail fixing ring in batches, or is sent to a stamping machine to stamp the scale; then, the central body of the nailing device is sent into a heat treatment workshop for heat treatment to obtain the required hardness of the product; and brazing the center body of the nailing device and the hard alloy sheet to complete the preparation of the electric hammer nailing device main body 1. The spring 2 is either purchased directly or pre-manufactured/custom-manufactured. The nail tail fixing ring 3 can be directly produced.

Assembling: the spring 2 and the nail tail fixing ring 3 are connected firstly, and then the spring 2 and the nail tail fixing ring are inserted from one end of the electric hammer nailing device main body 1 until one end of the spring 2 is clamped into the spring fixing groove 11.

Thirdly, use: when a constructor carries out nailing operation of the nail 5, the constructor only needs to install the electric hammer nailing device on the electric hammer with the electric pick function and then adjust the gear to the electric pick gear to nail the nail 5; fix nail 5 on the panel face with hand or pliers earlier, then overlap nail tail retainer plate 3 at 5 tail ends of nail, later the electric hammer circular telegram with nail 5 drive into suitable degree of depth can.

Example 2

In another embodiment shown in fig. 6 to 8, a simplified electric hammer tacker is provided, which comprises an electric hammer tacker body 1, a spring 2 and a nail tail fixing ring, wherein one end of the spring 2 is connected to the nail tail fixing ring, and the other end of the spring is connected to the electric hammer tacker body 1 through a detachable structure.

In this embodiment, the detachable structure includes a rubber fixing sleeve 4, and the inner surface and the outer surface of the rubber fixing sleeve are connected with the electric hammer tacker body 1 and one end of the spring 2 in an interference fit manner.

Can satisfy needs such as convenient maintenance, reduce cost, simplification dismouting technology equally through the fixed cover 4 of rubber as the detachable construction between electric hammer tacker main part 1 and the spring 2, in addition, the fixed cover 4 of rubber can also bring certain vibration/noise reduction function through damping characteristic.

In an optional implementation manner of this embodiment, the spring 2 is a cylindrical spring, and the other end of the spring 2 is also connected to the nail tail fixing ring 3 in an interference fit manner. Also realized dismantling between nail tail retainer plate 3 and the spring 2 like this, make things convenient for the two to be removable after damaging, further reduced use cost.

In the implementation modes and the expansion modes of the retrogressive scale 12 and the wear-resistant structure 13 of the nail tail fixing ring, the embodiment 2 can be consistent with the embodiment 1.

The above, only be the utility model discloses a preferred embodiment, it is not right the utility model discloses do the restriction in any form, all basis the utility model discloses a technical essence makes any simple modification and equal change to above embodiment, all falls into within the protection scope of the utility model.
