Together, when support plate 8 and pedestal 7 are connected, sliding block 81 is located at across sliding groove 5 outside cylinder 3, and 81 thickness of sliding block is less than sliding
The spacing of slot 5.
Sliding groove 5 includes a rectangular channel, and rectangular channel is parallel with syringe needle 1, and the both ends of rectangular channel respectively set one and support plate 8
Parallel slot, sliding groove 5 are located at 3 front end of cylinder.
Support plate 8 is fixedly connected with 4 top of sleeve, and 8 diameter of support plate is equal to 3 internal diameter of cylinder, 8 cylinder of support plate, 3 inner wall
It is slidably connected, 4 bottom of sleeve is installed with movable plate 9, and 9 radius of movable plate is identical as 8 radius of support plate, in movable plate 9 and cylinder 3
Wall is slidably connected.
Since sliding block 81 and support plate 8 are integrated, support plate 8 is fixedly connected with sleeve 4, can band when sliding block 81 moves
Moving sleeve 4 moves, and sleeve 4 is relatively-stationary with syringe needle 1, and sliding block 81 is also relatively-stationary with syringe needle 1, and sliding block 81 is in cunning
When being moved in dynamic slot 5, the position of syringe needle 1 can be changed according to position of the sliding block 81 in sliding groove 5.
Pedestal 7 is equipped between support plate 8 and syringe needle 1, pedestal 7 is connected with sleeve 4, and pedestal 7 is fixed with syringe needle 1 to be connected
It connects, syringe needle 1 is fixed on 7 top of pedestal vertically.
Cylinder 3 is equipped with sheath 6, and 2 diameters of outer ring , Tui Bing that sheath 6 is located at syringe needle 1 are equal to 4 internal diameter of sleeve, Qie Tui Bing 2
It is slidably connected with 4 inner wall of sleeve, sheath 6 is rubber structure, and sheath 6 is located at 3 top of cylinder, and sheath 6 and cylinder 3 are detachable
Connection is convenient for the dismounting of pedestal 7 and syringe needle 1 when sheath 6 unloads.
Embodiment 2
As shown in figure 4, embodiment 2 and embodiment 1 the difference is that：Sliding groove 5 in embodiment 2, in vertical rectangular channel
Both sides, there are more lateral slots, transverse groove to be equally distributed on rectangular channel, when wanting syringe needle 1 to stablize, sliding block 81 is located at cross
Into slot, when transverse groove number increases, there are sliding block 81 more transverse grooves can coordinate so that syringe needle 1 has relative to sheath 6
More kinds of needle lengths.
In actual use, first support plate 8 is fixedly connected with 4 top of sleeve, support plate 8 and sleeve 4 is placed
In in cylinder 3, movable plate 9 is fixed in 4 bottom of sleeve, movable plate 9 and support plate 8 are respectively positioned in cylinder 3, movable plate 9 and support
Plate 8 is for maintaining being relatively fixed between cylinder 3 and sleeve 4, installation pedestal 7 and syringe needle 1 in support plate 8, finally by sheath 6
Coordinate with cylinder 3 and installs.For in use, support plate 8 is concordant with 5 bottom of shifting chute, it is most lower to be located at shifting chute 5 for sliding block 81 at this time
In the transverse groove at end, when wanting in use, the cross of more top can be located at according to actual use situation adjustment sliding block 81 position, sliding block 81
When to slot, the length that syringe needle 1 leans out sheath 6 is more next, when syringe needle 1, which leans out length arrival, needs length to be used, by sliding block 81
Slide to nearest transverse groove so that 1 vertical direction of syringe needle is in stationary state, at this time promotion Tui Bing 2, liquid in shot sleeve 4；
After syringe use, sliding block 81 is slided in 5 the lowermost transverse groove of sliding groove, syringe needle 1 is located under sheath 6 at this time
Side, syringe and syringe needle 1 are dismantled, and cylinder 3 is used for next time.
