Description

Driver structure of the screwdriver

The present invention relates to the technical field of hand tools, and in particular to a driving structure of a screwdriver tool for twisting a screw member to rotate.

The screwdriver has a wide variety of tools, such as a screwdriver bit, a screwdriver, a post, and the like. The driver tool has a driving structure which is a functional shape portion of one end of the screwdriver tool, for example, a letter shape, a cross shape, a star shape, a rice shape, and the like. The driving structure has a set of contact surfaces, and the set of contact surfaces fits into a groove formed in the screw member for twisting the screw member to rotate to achieve the purpose of locking or unscrewing.

Each of the contact faces may be a flat surface or a curved surface. When the twisting screw is rotated, the contact surface is slid relative to the screw member, and even the screw member is detached from the driving structure of the screwdriver tool.

In order to overcome this problem, the easiest way is to let the screwdriver tool produce a slip-proof function. Therefore, some of the driver tools have more than one or more horizontal stripes in the drive structure. The set of horizontal stripes protrudes side by side from the contact surface in an attempt to cause the screwdriver to produce a slip-resistance effect on the screw.

In practical use, the horizontal stripes do not allow the drive structure to have an effective anti-slip effect, so that the screw joints still leave the contact surface of the screwdriver tool.

Therefore, how to improve the driving structure of the screwdriver tool has become an urgent problem to be solved in this creation.

In view of this, this creation provides a new screwdriver tool, the main purpose of which is to improve the driving structure of the screwdriver tool by using the surface treatment of the die, and relatively improve the anti-slip function to reduce the slippage of the screw.

Due to the above object, the starter tool of the present invention has a first end, and a driving structure for rotating the screwing member is provided at the first end. The driving structure comprises: a set of contact faces formed at a portion adjacent to the first end of the screwdriver tool; and at least one diamond layer, wherein the diamond layer refers to a composite material composed of a plurality of diamond grains bonded to the contact faces Layer, each diamond grain has a Mohs Scale Of Mineral Hardness of 9 or more.

Wherein, the diamond layer is bonded to the entire area of the contact surface, 1/2 or 1/3. The diamond layer also has a bonded construction that causes the diamond grains to adhere to the contact surface to form a composite diamond layer.

The combined construction is made in one of the following ways:

The first method is to plate one of nickel, cobalt, copper, solder, gold, palladium, tin, and silver metal materials on the contact surface to form an adhesion layer.

The second method is to use a metal gasifying agent as a catalyst to bond the diamond crystal grains to the adhesion layer formed by the contact surface.

In this way, the creation tool of the present invention adopts a combination structure in which the diamond crystal grains are attached to the contact surface, thereby not only improving the driving structure, but also improving the anti-slip function of the screwdriver tool and relatively reducing the slippage rate of the screwing member.

In order to make the above purposes, features and advantages of this creation easier It is to be understood that one or more preferred embodiments are described in detail with reference to the accompanying drawings.

In the first to third figures, the first embodiment of the screwdriver tool 10 is drawn. In the embodiment, the screwdriver tool 10 is a screwdriver (also called a screwdriver) having a first end 11 and a second end 12, and a rod body between the first end 11 and the second end 12 13 is coupled to a structure of a grip 14. Wherein, one of the two ends of the rod body 13 is covered by the grip 14, and the two have a transmission relationship in the same direction. The other end of the rod 13 serves as the first end 11 of the driver tool 10, and a drive structure 20 for twisting the screw (not shown) is made. Thus, the grip 14 is adjacent to the second end 12 of the driver tool 10.

In the figure, the drive structure 20 consists of a set of contact faces 21 and a set of diamond layers 23. Wherein, the set of contact faces 21 are formed at a portion of the screwdriver tool 10 adjacent to the first end 11 , and each of the contact faces 21 is a concave curved surface extending from the free end of the rod body 13 toward the grip 14 so that the rod body 13 The portion adjacent to the first end 11 of the screwdriver tool 10 becomes a star-shaped functional body. As such, the drive structure 20 has a set of corners 22, each of which is 22 Between adjacent two contact faces 21.

In addition, the value of the set of diamond layers 23 is equal to the value of the set of contact faces 21 such that the diamond layer 23 is attached to the outer surface of the corresponding contact surface 21. Wherein, the diamond layer 23 is bonded to the entire area of the contact surface 21, and each diamond layer 23 refers to a composite material layer in which a plurality of diamond crystal grains 24 are combined with the contact surface 21, and each diamond crystal grain 24 has 9 or more. Mohs Scale Of Mineral Hardness.

Specifically, the diamond layer 23 also has a bonding structure 25 that adheres to the contact surface 21 to form the composite diamond layer 23 in one of the following manners.

The first method is to electroplate one of nickel, cobalt, copper, solder, gold, palladium, tin, silver metal materials on the adhesion layer formed by the contact surface 21, and the adhesion layer bonds the diamond crystal grains 24 to the contact surface 21 Above.

The second way: using the metal gasifying agent as a catalyst, the diamond crystal grains 24 are combined with the contact faces 21 to form a composite material layer.

The metal oxidizing agent referred to herein means aluminum oxide, boron trioxide, germanium dioxide, chromium oxide, manganese dioxide, ferric oxide, triiron tetroxide, copper oxide and lead tetraoxide. First, the non-metallic diamond grains 24 are bonded to the metal rod 13 to form a composite material.

In any event, the diamond grain 24 is partially exposed to the surface 26 of the bond formation 25, giving the screwdriver tool 10 several advantages below:

First, the diamond layer 23 increases the hardness of the screwdriver tool 10, and has a low friction coefficient and a wear-resistant feature.

Second, the diamond layer 23 enhances the mechanical properties of the screwdriver tool 10, has a high degree of stability, and relatively extends the lifespan.

Third, the corners of the diamond die 24 can effectively bite the screw member, so that the screw member does not easily slide out of the screwdriver tool 10.

Fourth, the corners of the diamond crystal grains 24 are fine, and even if the screw members are bitten, no excessive marks are generated.

Figures 4 and 5 illustrate a second embodiment of the screwdriver tool 30, which is constructed substantially the same as the first embodiment, with the following differences:

First, not a screwdriver. The driver tool 30 is a post 33 and a housing 34 from a first end 31 to a second end 32. The housing 34 is electrically non-conductive and encases a partial post 33 that is coupled in a co-rotating relationship. The free end of the post 33 is exposed to the housing 34 and serves as the first end 31 of the driver tool 30, allowing the drive structure 20 to be placed adjacent the free end of the post 33.

Second, the values of the set of contact faces 21 are two sides such that the portion of the post 33 adjacent the first end 31 of the screwdriver tool 30 becomes a functional body of the word.

Third, the diamond layer 23 is bonded to the contact surface 21 by an area of about 1/2. Briefly, the contact surface 21 is divided into two, the portion defining the contact surface 21 near the first end 31 of the screwdriver tool 30 is the front half, and the portion remote from the first end 31 is considered the rear half. The front half of the contact surface 21 is covered with diamond grains 24, and the second half is smooth without crystal grains.

Figures 6 and 7 illustrate a third embodiment of the driver tool 40, which is constructed substantially the same as the first or second embodiment, with the following differences:

First, the screwdriver tool 40 is neither a screwdriver nor a post but a screwdriver. The driver tool 40 is a body 43 from a first end 41 to a second end 42. The free end of the body 43 acts as a first end 41 of the driver tool 40, allowing the drive structure 20 to be disposed adjacent the free end of the body 43.

Secondly, the value of the contact surface 21 of the group is four sides, so that the body 43 is adjacent The portion of the first end 41 of the proximal tool 40 becomes a functional feature of the cross.

Furthermore, the diamond layer 23 is bonded to the area of the contact surface 21 by about 1/3. In other words, the contact surface 21 is divided into three portions, the diamond grains 24 are covered by one-third of the total area, and the remaining two-thirds of the total area is smooth without any grains. The diamond layer 23 is also in close proximity to the first end 41 of the screwdriver tool 40.
