Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain this utility model, is not used to limit this utility model.
Embodiment one:
Refer to Fig. 1, anti-snag of the present utility model is drawn the embodiment one of shell fragment be illustrated below.
The anti-snag of the present embodiment draws shell fragment 100, is mainly used in electron trade, including installed part 10, elasticity
Contact 20 and retaining piece 30, draw each parts of shell fragment 100 to be described further below to anti-snag:
Installed part 10 is to connect setting with for parts, and it also serves as welded connections simultaneously, so that whole
Anti-snag is drawn shell fragment 100 to be welded to connect and is being specified position；
Resilient contact 20 includes being connected to connect in order to contact site 21, the one end contacted with required contact object
Contact portion 21 and the other end are connected to installed part 10 to support first supporting part 22 and one end of contact site 21
Be connected to contact site 21 and the other end near installed part 10 so that installation can be supported when contact site 21 is compressed
The second supporting part 23 of contact site 21 is supported on part 10；
Retaining piece 30 is located on installed part 10, and is slidably connected with the second supporting part 23；
Wherein, contact site the 21, first supporting part 22 and installed part 10 form the first loop structure, with in
When contact site 21 is compressed can elastic buffer this compress active force and contact site 21 can be made to return back to initial bit
Put；Contact site the 21, second supporting part 23, retaining piece 30 and installed part 10 form second servo loop structure,
With when contact site 21 is compressed can elastic buffer this compress active force and contact site 21 can be made to return back to initially
Position.
Owing to the first supporting part 22 of resilient contact 20 is connected with installed part 10, and the second supporting part 23
It is held part 30 to hold, can effectively reduce the risk that resilient contact 20 draws with other component contact hook；Separately
Outward, due to the first loop structure and the setting of second servo loop structure, it is greatly improved the general safety system of shell fragment
Number, service life and reliability.
Referring again to Fig. 1, specifically, the normal slope of contact site 21 is in the normal of installed part 10, accordingly,
When contact site 21 presses on contact object, the active force that contact object is produced by contact site 21 is less, with
Time, contact object is the least to the counteracting force of contact site 21, and so, can beneficially improve whole anti-
Hook draws the elastic reliability of shell fragment 100, extends its service life.
Simultaneously, for the ease of processing, to improve production efficiency, installed part 10, resilient contact
20 and retaining piece 30 be formed in one setting；And it is preferred that by installed part 10, resilient contact 20 and

Processing and manufacturing；Simultaneously, by upper linkage section 221 and the setting of lower linkage section 222, it is beneficial to connect
It is independent of each other when contact site 21, installed part 10.
And this changeover portion 223 is arc structure, in order to processing and manufacturing, certainly, this changeover portion 223 also may be used
For other shape and structure, such as bending etc..Selectively, linkage section 221 and lower linkage section 222 on this
For be arrangeding in parallel.
Please continue to refer to Fig. 1, the preferred structure of retaining piece 30 is, it side including being located at installed part 10
The first retaining piece 31 held and the second retaining piece 32 of another side being located at installed part 10, the first fixing
Part 31 is oppositely arranged with the second retaining piece 32, and shape between the first retaining piece 31 and the second retaining piece 32
Become to have and be available for the second supporting part 23 and stretch into accommodating containing cavity 33 near one end of installed part 10；
The both sides correspondence of the second supporting part 23 is slidably connected with first retaining piece the 31, second retaining piece 32.
By the first retaining piece 31 and setting of the second retaining piece 32, except being easy to production and processing, also can be square
Just being slidably connected between the second supporting part 23 is realized.
Specifically, the both sides of the second supporting part 23 are convexly equipped with slide bumping 231, the first retaining piece 31 respectively
Being provided with the first sliding tray 311, the second retaining piece 32 is provided with the second sliding tray 321, is positioned at the second support
The slide bumping 231 of the side in portion 23 is slidably matched with the first sliding tray 311, is positioned at the second supporting part 23
The slide bumping 231 of opposite side be slidably matched with the second sliding tray 321.Wherein, two slide bumpings
231 respectively with being slidably matched of first sliding tray the 311, second sliding tray 321, not only simple in construction, and
And also can be effectively realized being slidably connected between retaining piece 30 and the second supporting part 23.
In order to simplify the processing sets up of the first sliding tray 311, it is preferred that the first retaining piece 31 upward one
Side extends and is bent with the first kink 34, first kink the 34, first retaining piece 31 and installed part
