The other end of one connecting rod 300 far from the first screw rod 100 passes through the second connecting rod 420 between two neighboring extension rod 410 and fixes
Connection.The second external screw thread 430, the hand of spiral phase of the second external screw thread 430 and the first external screw thread 110 are provided on extension rod 410
Together.Specifically, one of extension rod 410 is integrally formed with head rod 300, and two neighboring extension rod 410 and second connects
Extension bar 420 is integrally formed, and further decreases the processing cost of attachment screw 10.Extension rod 410 is coaxially set with the first screw rod 100
It sets.The length of multiple extension rods 410 can be identical or differs, and can also formulate different length according to actual installation requirements
Extension rod.One of extension rod 410 is connected to the one end of the first fixed link 310 far from first screw rod 100.Further
Ground, the diameter of extension rod 410 is identical as the diameter of the first screw rod 100, may be implemented to facilitate installation, facilitates processing.
Wherein, the second external screw thread 430 is rectangular thread, trapezoidal thread, saw-tooth thread or triangle thread.Specific to this
In embodiment, the second external screw thread 430 is identical as the first external screw thread 110, screw pitch and the first external screw thread of the second external screw thread 430
110 screw pitch is also identical, and the second external screw thread 430 is trapezoidal thread, can effectively improve the processing efficiency of attachment screw 10, reduces
The cost of attachment screw 10, further increases installation effectiveness.Certainly, in other embodiments, the second external screw thread 430 can be with
First external screw thread 110 differs.For example, the first external screw thread 110 be trapezoidal thread, the second external screw thread 430 be triangle thread, three
Angular screw thread has good self-locking property, can increase attachment screw 10 and plank and the stability of knob connection.
The diameter of second connecting rod 420 is less than the diameter of extension rod 410, can facilitate the second connecting rod of severing 420.Phase
In adjacent two extension rods 410, wherein an extension rod 410 is close to the first screw rod 100, another extension rod 410 is far from the first screw rod
100.Second connecting rod 420 includes the second fixed link 421 and the second severing bar 422, and the second fixed link 421 is located remotely from first
Between the extension rod 410 of screw rod 100 and the second severing bar 422, the one end of the second severing bar 422 far from the second fixed link 421 connects
It is connected to one end of the extension rod 410 close to the first screw rod 100.
Specific in present embodiment, the straight direction radially adjacent to the first screw rod 100 of the second severing bar 422 gradually subtracts
It is small.During severing, the second fixed link 421 is clamped using pinch off tool, curved dynamic pinch off tool can make the second severing bar
422 one end is disconnected with the extension rod 410 close to the first screw rod 100, can obtain the attachment screw at end stingless angle and clast
10.Certainly, in other embodiments, the diameter of the second severing bar 422 can be less than the second fixed link 421, as long as realization side
Just severing.
Further, the length of the second severing bar 422 is less than the length of the second fixed link 421, can improve attachment screw
10 intensity prevents attachment screw 10 to be broken during the installation process.Specific in present embodiment, the length of the second fixed link 421
The sum of length of degree plus the second severing bar 422 is 2-5mm, and pinch off pincers 500 can be made effectively to clamp the second fixed link 421.The
The length of two severing bars 422 is less than 1mm, increases the intensity of attachment screw 10.
Attachment screw 10 realizes the adjusting of entire length by cutting head rod 300 or the second connecting rod 420.Specifically
Ground can pass through the second connecting rod 420 or the first of severing according to the thickness and model of actual plank and the installation requirements of knob
Connecting rod 300 realizes the length adjustment of entire attachment screw 10, to adapt to the connection of the plank and knob of different-thickness and model,
Realize the stability and beauty of connection.
Attachment screw 10 can be carbon steel screw.The mechanical strength of carbon steel screw is low, plasticity, good toughness, holds under cold state
Easy die forming is easy machining, good welding performance.Specifically, case-carbonizing or the cyaniding processing of attachment screw 10, can be with
Improve the hardness on 10 surface of attachment screw.Specific in present embodiment, the surface of attachment screw 10 can be with nickel plating, the company of raising
The stability and bonding strength connect.
The operation principle of above-mentioned attachment screw 10 is as follows：
Please refer to fig. 4 to fig. 6, with attachment screw 10 include first screw rod 100, a head rod 300, three
Illustrate for extension rod 410 and two the second connecting rods 420, severing head rod 300 or the second connecting rod can be passed through
420, realize the attachment screw 10 of 4 kinds of different size length requirements.To prevent the screw of different size from leading to screw and peace occur
The unmatched mistake of dress demand formulates the attachment screw 10 of unified specification.Second screw rod 400 of the attachment screw 10 includes three
Extension rod 410, two the second connecting rods 420, the second connecting rod 420 are set between two neighboring extension rod 410.Second screw rod
400 are connected to the one end of head rod 300 far from the first screw rod 100.One of which plank 610 and the connection of knob 620 need
Remove an extension rod 410, clamps second connecting rod 420 of 500 severings far from the first screw rod 100 with pinch off so that adjacent two
A extension rod 410 detaches, and realizes the adjusting of 10 entire length of attachment screw.With screwdriver 630 by the connection spiral shell after length adjustment
Nail 10 is fixedly connected with plank 610 and knob 620.
The attachment screw 10 adapts to the connection of the plank and knob of different-thickness and model, realize the stability of connection with
