Description

Technical Field

[0001] The utility model relates to a card removal needle, in particular to a novel mobile phone card removal needle. Background Art

[0002] At present, most of the known mobile phone card ejection needles are simple needle-type structures, with a handle on the upper part and a needle on the lower part. Whether it is carried alone or hung together with keys, the needle is easy to hurt people, which is inconvenient to carry. Summary of the invention

[0003] In order to overcome the disadvantage that the existing card removal needle is easy to hurt people, the utility model provides a new mobile phone card removal needle, which is not easy to hurt people whether it is carried alone or hung together with keys.

[0004] The utility model adopts the technical scheme to solve the technical problem as follows: the card removal needle adopts an integrated symmetrical structure design, the upper half is the handle part, the lower half is the needle part, and is made of high-strength stainless steel.

[0005] The handle part is designed with an oval key ring hole, which can be hung on the key ring together with the key. The oval key ring hole can increase the freedom of the card removal needle on the key ring, making it more convenient to carry.

[0006] The needle part is designed as an 'M'-shaped structure, with the needle in the middle and tooth guards on both sides, which play a role in protecting the needle.

[0007] The design length of the mouthguard is greater than the length of the needle, and the mouthguard can prevent the needle from pricking people to the greatest extent.

[0008] The needle root is designed with an arc transition, eliminating the influence of stress concentration on the needle.

[0009] The root design of the tooth guard adopts arc transition, which eliminates the influence of stress concentration on the tooth guard.

[0010] The inner side of the top of the mouthguard teeth is designed to be rounded, which can prevent the mobile phone from being scratched to the greatest extent.

[0011] The outer side of the top of the mouthguard teeth is designed to be rounded to prevent scratches to the greatest extent.

[0012] The design width of the mouthguard is 5-8 times the diameter of the needle, and the structural strength of the mouthguard is relatively large and not easy to deform; the problem of the mouthguard piercing people is eliminated, and at the same time the needle is protected to prevent the needle from piercing people.

[0013] The utility model has the beneficial effects of novel structure, unique design, convenience and practicality, can be carried alone, and can also be hung on a key ring together with keys, so it is convenient to carry around without pricking people. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0015] Figure 1 It is the front view of the utility model.

[0016] Figure 2 It is a cross-sectional view of the utility model.

[0017] The legend in the figure: 1-handle part, 1-1-oval keychain ring hole; 2-needle part, 2-1-needle, 2-2-toothguard. DETAILED DESCRIPTION
