Convenient.
In order to make fixed part on connector can fixation reliable, further, described connector outer peripheral face is offered
Having cannelure, described fixed part inner peripheral surface to offer to match projection with described cannelure, described projection is arranged on described annular
In groove, owing to connector outer peripheral face offers cannelure, fixed part inner peripheral surface offers and matches projection with cannelure, and projection sets
Putting in cannelure, fixed part is connected on connector, limits fixed part and moves axially along connector, can only be with connector
Center rotating, it is ensured that fixed part is the most reliable and the most stable with connecting portion.
The beneficial effects of the utility model are: this utility model needle point protection device in use, by pipe shaft and pipe shaft
Between be mutually rotationally connected the protection set being combined into, needle point is arranged in the stop part in the cavity body of pipe shaft, prevents needle point
Detach protection set, when needle point bending, between pipe shaft and pipe shaft be can mutual rotation bending, can bend between pipe shaft and join
Closing the needle point of bending, needle point also is able to be effectively obtained protection when bending, prevents staff's imprudence from stabbing and infecting disease
Sick risk；By limited post, each pipe shaft is together in series, is operable to when needle point literary composition bends convenient；Owing to connecting
External side face offers cannelure, and fixed part inner peripheral surface offers and matches projection with cannelure, and projection is arranged in cannelure,
Fixed part is connected on connector, limits fixed part and moves axially along connector, can only rotate centered by connector, it is ensured that
Fixed part is the most reliable and the most stable with connecting portion；Needle point after bending can effectively be played a protective role by this utility model,
Simple to operation, reliable and stable during work.

Detailed description of the invention
Presently in connection with accompanying drawing, the utility model is described in more detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of needle point protection device, including fixed part 1, protection set 2 and connector 3, described fixed part
1 is fastened on described connector 3, and the rotation of described protection set 2 is arranged on described fixed part 1, and described protection set 2 has some head
The pipe shaft 4 that tail is connected, adjacent two pipe shafts 4 are positioned at symmetry on previous pipe joint body 4 and offer draw-in groove 5, and adjacent two pipe shafts 4 are positioned at rear one
Being outward extended with claw 6 on pipe joint body 4, described claw 6 matches with described draw-in groove 5, and described claw 6 rotates and is arranged on described card
