[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4, a highly safe injection needle, comprising a syringe 1, a propulsion assembly 2, a needle 3 and a connecting seat 4, wherein one end of the syringe 1 is slidably connected to the propulsion assembly 2, and the other end of the syringe 1 is provided with an output head, one end of the connecting seat 4 is plugged with the output head, and the other end of the connecting seat 4 is provided with a needle 3 that passes through the output head, and the connecting seat 4 is also provided with a protective assembly for protecting the needle 3, the protective assembly comprises a protective cover 5 and a breaker, the protective cover 5 is provided with a storage cavity with a side opening for accommodating the needle 3, the protective cover 5 is plugged with the connecting seat 4, one side of the storage cavity is provided with a card slot adapted to the breaker, and the other end of the storage cavity is provided with an insertion hole adapted to the breaker, and the breaker comprises a breaking plate 6 and a supporting plate 7, and the breaking plate 6 is connected to the supporting plate 7 in an L shape.

[0023] Before the injection needle is used, the breaker is separated from the protective cover 5. The protective cover 5 only provides protection for the needle tip of the needle 3 on the connecting seat 4. The connecting seat 4 is plugged into the output head of the syringe 1. After the feeding of the liquid medicine is completed by the propulsion component 2, the protective cover 5 is sleeved on the connecting seat 4. The breaking plate 6 protrudes from the root of the connecting seat 4 close to the needle 3. The breaking plate 6 cooperates with the supporting plate 7 to be inserted into the insertion hole for stable feeding. The breaking plate 6 breaks the needle 3 and the breaker is stuck in the card slot. At this time, the broken part of the needle 3 is enclosed in the protective cover 5 and cannot be taken out, thereby ensuring the safety of equipment destruction.

[0024] In order to ensure the stable feeding of the breaker, in this embodiment, the breaking plate 6 is provided with a bevel 8 at one end close to the needle head 3 to ensure the stability of the broken needle head 3. At the same time, the breaking plate 6 is provided with a rough surface at one end close to the connecting seat 4. Reinforcing ribs 9 are provided between the breaking plate 6 and the supporting plate 7. The reinforcing ribs 9 are arranged in two groups symmetrically. The reinforcing ribs 9 are arranged at both ends of the needle head 3 and are arranged parallel to the needle head 3, thereby ensuring the overall strength of the breaker. The upper and lower heights of the breaking plate 6 are greater than the height of the supporting plate 7. The side section of the breaker is T-shaped to ensure the stability of its feeding.

[0025] It is found in actual use that the above structure is prone to loss of the breaker. For this reason, an elastic rope 10 connected to the support plate 7 is provided in the card slot. While ensuring the stable use of the breaker, it does not affect the connection between the protective cover 5 and the connecting seat 4 and the needle 3, and can also prevent the breaker from being lost.
