Description

Technical Field

[0001] The present invention relates to the technical field of nail guns, and more particularly to a multi-functional nail gun. Background Art

[0002] Currently, a nail gun is a tool used to bind multiple sheets of paper together for preservation.

[0003] Chinese invention with the authorization announcement number CN109571372A discloses a multi-functional stapler, including: a housing and an adjusting device. In order to achieve the positioning of nails with different widths and different specifications, a part of the adjusting device is arranged outside the housing to adjust the depth of the nail outlet slot. The adjusting device includes a first adjusting member, a second adjusting member, a first knob, and a pressing piece.

[0004] The first adjusting member includes a first adjusting member body, an adjusting member convex block, and a stepped groove. The adjusting member convex block is arranged on one side of the adjusting member body and inserted into the through hole of the nail outlet member; the stepped groove is arranged on the other side of the adjusting member body. The bottom surface of the stepped groove includes a low-level stepped surface, a high-level stepped surface, and a smooth inclined surface, and the smooth inclined surface connects the low-level stepped surface and the high-level stepped surface. An adjusting member sliding groove is opened on the housing, which is linear and used to accommodate the second adjusting member.

[0005] The first knob passes through the first knob through hole, a part of which protrudes outside the housing, and the other part is connected to the second adjusting member. When the first knob is toggled up and down, the second adjusting member slides up and down in the adjusting member sliding groove. One end of the pressing piece is fixedly connected to the first knob and / or the second adjusting member, and the other end is inserted into the stepped groove and tangent to the bottom surface of the stepped groove. When the first knob is toggled up and down, the pressing piece slides up and down in the adjusting member sliding groove.

[0006] The first knob through hole includes a first gear position and a second gear position. The first knob is used to adjust the depth of the nail outlet slot so that the nail outlet slot can accommodate nails of different thicknesses. When the first knob is toggled, the pressing piece and the second adjusting member move synchronously.

[0007] During the actual production and installation process of the above-mentioned adjusting device, by setting the adjusting device, the nail gun can adjust the position of the staples by adjusting the position of the pressing piece relative to the second adjusting member during use. When the width of the staples changes, in order to enable the nail gun to eject nails normally, the pressing piece is protruded from the second adjusting member, so that the position of the staples relative to the second adjusting member moves backward, and the ejection of staples with different widths can be achieved without changing the position of the nail outlet member of the nail gun.

[0008] However, due to the larger number of components of the above overall adjusting device, multiple components need to be installed in the installation order, and the installation steps are cumbersome and the installation cycle is long. Summary of the Invention

[0009] The object of the present invention is to provide a multi-functional nail gun, which has the effects of simplifying the installation steps of the adjusting device, reducing the production cost of the adjusting device, and having a longer service life.

[0010] The above object of the present invention is achieved by the following technical solutions:

[0011] A multi-functional nail gun includes a housing and an adjusting device provided on one side of the housing. The adjusting device includes a clamping piece provided in the housing and an adjusting plate mounted on the clamping piece. The clamping piece is axially slidably mounted on the housing, and an adjusting member is provided between the clamping piece and the housing.

[0012] By adopting the above technical solutions, during installation, only the clamping piece and the adjusting plate need to be slidably mounted on the housing, and then the clamping piece and the adjusting plate are mutually clamped. Subsequently, the relative position of the clamping piece can be adjusted by adjusting the position of the clamping piece, which simplifies the structure of the adjusting device, facilitates the assembly of the adjusting device, and facilitates the installation between the adjusting device and the housing, reduces the production cost of the adjusting device, and prolongs the service life of the nail gun.

[0013] The present invention is further configured as follows: The adjusting member includes a plurality of positioning protrusions provided on the side of the clamping piece away from the adjusting plate and a clamping groove provided on the side wall of the housing. An adjusting protrusion is provided above the positioning protrusions on the clamping piece, and a part of the adjusting protrusion protrudes outside the housing. An adjusting through hole for adjusting the adjusting protrusion is provided on the side wall of the housing. When the positioning protrusions are embedded in the clamping groove, the adjusting plate remains horizontal. When the positioning protrusions are separated from the clamping groove, the adjusting plate moves towards the side away from the clamping piece.

[0014] By adopting the above technical solution, the entire clamping piece faces the direction of the staple in a plane. When the position of the staple needs to be adjusted, the clamping piece is moved so that the adjusting protrusion on the clamping piece separates from the clamping groove on the housing, causing the clamping piece to bulge slightly relative to the housing, and thus causing the adjusting plate to shift towards the side away from the clamping piece. The position of the nail driving piece relative to the adjusting plate remains unchanged, enabling the nail ejecting piece of the stapler to achieve single nail ejection for staples with a narrower width. In the prior art (CN109571372A), to prevent collision between the nail driving piece and the first adjusting piece on the protrusion of the nail ejecting piece, a convex block is designed at the top of the nail ejecting piece. When the nail driving piece is knocked down, it can be guided by the convex block. However, to ensure that the convex block can accurately guide the nail driving piece, the height of the convex block needs to be set to the height at which the first adjusting piece protrudes from the nail ejecting piece, which requires a high machining accuracy for the convex block and a large production difficulty. The above solution simplifies the production of the adjusting plate by setting the adjusting plate as a flat plane, reducing the production cost of the adjusting plate.

[0015] The present invention is further configured such that: a stepped groove is provided on the side of the adjusting plate facing the housing, and the surface of the stepped groove is a plane.

[0016] By adopting the above technical solution, the adjusting plate can achieve positioning for staples of different sizes. In the nail driving piece and the first adjusting piece in the prior art (CN109571372A), during use, in the original prior art (CN109571372A), when the convex block on the nail ejecting piece is worn, the nail driving piece is prone to impact with the first adjusting piece, generating a large amount of noise, and greatly reducing the service life of the first adjusting piece. In the present invention, the side wall of the stepped groove is set as a plane, so that the nail driving piece will not collide with the first adjusting piece during nail driving, resulting in a large amount of noise generated by the nail driving piece, greatly reducing the noise pollution during the use of the stapler, and effectively improving the service life of the adjusting plate.

[0017] The present invention is further configured such that: the bottom of the adjusting plate is flush with the bottom of the housing, forming a positioning plane at the bottom of the housing.

[0018] By adopting the above technical solution, since the convex block for guiding the nail driving piece is omitted on the adjusting plate, when the nail driving piece strikes the staple, it can remain perpendicular to the adjusting plate, reducing the probability of the staple shifting relative to the adjusting plate. Therefore, there is no need to extend the adjusting plate to guide the staple, enabling the bottom of the stapler housing to be level with the position where the staple needs to be nailed tightly, so that the nail ejection direction of the stapler is perpendicular to the object, reducing the probability of the nail ejection direction of the stapler shifting.

[0019] The present invention is further configured such that: a positioning groove is formed on one side of the clamping piece facing the adjusting plate, and a part of the adjusting plate is embedded in the positioning groove.

[0020] By adopting the above technical solution, during the movement of the clamping piece, it can play a certain guiding function through the positioning groove and the adjusting plate, making the movement of the clamping piece more stable; and the clamping piece can be limited through the positioning groove and the adjusting plate, reducing the probability that the clamping piece exceeds the movement stroke during the movement process.

[0021] The present invention is further configured such that: a sliding groove for the clamping piece and the adjusting plate to slide is formed on the housing, an extending part extending upward is provided at the top of the clamping piece, and the extending part is embedded in the sliding groove.

[0022] By adopting the above technical solution, the stability of the movement of the clamping piece is further improved by setting the sliding groove; by setting the extending part, during the installation of the clamping piece, a person can hold the clamping piece to install the clamping piece, making the installation of the clamping piece more convenient.

[0023] The present invention is further configured such that: positioning flanges extending horizontally outward are symmetrically provided on both sides of the adjusting plate, placing grooves for the positioning flanges to be embedded are formed on the side wall of the housing, and the top and bottom of the positioning flanges are respectively attached to the top and bottom of the placing grooves.

[0024] By adopting the above technical solution, the adjusting plate can be positioned relative to the housing through the positioning flanges located on both sides of the adjusting plate, thereby improving the stability of the installation of the adjusting plate.

[0025] The present invention is further configured such that: the housing includes a right housing and a left housing, a positioning block is provided on the right housing, and an embedding groove for the positioning block to be embedded is provided on the left housing.

[0026] By adopting the above technical solution, the stability after the installation of the right housing and the left housing is improved.

[0027] In summary, the beneficial technical effects of the present invention are as follows:

[0028] 1. By setting the adjusting device, the installation steps of the adjusting device are simplified, the installation cycle of the nail gun is shortened, and the installation efficiency of the nail gun is improved.

[0029] 2. By setting the adjusting member, after the adjusting device completes the adjustment, the stapler can eject staples of different widths, which simplifies the processing technology of the adjusting plate, further shortens the processing cycle, and improves the production efficiency of the stapler;

[0030] 3. By setting the adjusting plate to be flush with the bottom of the housing, the stapler can be directly and stably placed at the position where stapling is required, so that when the stapler ejects the staples, the ejection direction of the staples is not likely to shift.
