The cam follower 102 of corresponding claw 58 extends through the slit 104 being formed in the inner wall 106 of shell 30 simultaneously
And enter the slit 126 of plate 124.Moving down for actuator 108 relative to shell causes inclined cam face 128 to make respectively
The sliding of claw 58 separates.As shown in Figure 15, actuator 108 is in from the first position that shell extends.As shown in Figure 15,
In the case where claw 58 is in the closed position, cam follower 102 is accepted in corresponding slit 126 and is disposed in
The bottom end of corresponding slit.As shown in Figure 16, actuator 108 moves down the cam face 128 enable in plate 124
Make cam follower 102 and the movement of corresponding claw 58 and leaves each other.Claw 58 is biased in together arrival and closed by spring 98
Position and the plate and actuator is made to return to original position.In further embodiments, spring or other suitable biasing members
It is arranged in the shell so that actuator 108 returns to original position shown in Figure 15.
Shell 30 includes unloading device 130, which is used to help to remove the interior shield 24 of a needle assemblies and nothing
Patient is needed to operate interior shield.As shown in Figures 10 and 11, extractor 130 includes side wall 132, which limits opening wide for shell
Channel between top end part and the chamber of bottom end.Extractor 130 can be formed by the sheet metal clip for being attached to side wall 132,
Wherein, which includes sharp edge to engage interior shield.Roof 134 includes the slit 136 of substantially keyhole.It is showing
Embodiment in, roof 134 have concave surface 138 with help interior shield 24 is directed in slit 136.Keyhole it is narrow
Slot 136 has the generally circular opening 140 increased and the opening 142 longitudinally extended, and the width of the opening longitudinally extended is small
In the diameter of circular open 140.The size of circular open 140 is slightly larger than the outermost dimension of interior shield 24, so that internal shield
Cover can not passed through interferingly.
The distal portion 144 of longitudinal portion 142 includes at least one tooth 146, at least one tooth is relative to circular open 140
It protrudes inwardly from and limits recessed area 148.Tooth 146 is formed with inclined surface in the illustrated embodiment, the inclined table
Face forms sharp tip 150.In the illustrated embodiment, inclined surface 152 is interior to allow along direction inclination generally downward
Portion's shield 24 slips over the tip and resists removes interior shield in upward direction.Tooth 146 be it is fully flexible so that internal
Shield can be pushed over the opening with enter shell in pallet or other receiving devices.The inner longitudinal edge of longitudinal slit 142
154 are formed with inclined surface 156, which converges to the edge 158 of sharpening.Inclined surface 156 is towards shell
Bottom end tilt down with during the use of device help grasp interior shield.Form the actuator of the covering of shell
108 include opening 160, and the lasso 162 extended downwardly extends from the inward flange of the opening 160.As shown in Figure 8, lasso 162
Size matches the outside dimension of the side wall 132 of extractor 130, so that lasso 162 slips over extractor during use.
Component can receive a needle assemblies to help user that the interface is attached to delivery pen and operate without user
The casing of needle interface and exposure.During use, label is removed from external covering part and a needle assemblies are placed to shell
In 30 lasso, so that needle assemblies are downwardly into the open region limited as shown in Figure 6 by claw 58.Needle assemblies by
The tooth 92 of the claw 58 and leg 80 that engage the outer surface of bottom external covering 22 is kept.On the inclined surface of corresponding claw
Pawl 78 engages the rib on the outer surface of external covering part to prevent external covering part from rotating relative to claw.
As shown in Figure 8, then delivery pen passes through the opening in the lasso 162 on the lasso 118 and shell of actuator 108
It is inserted into engage the needle interface of a needle assemblies.The delivery pen is rotated to engage the internal screw thread on needle interface to be connected to conveying
Pen.As shown in Figure 9, there is the delivery pen of needle interface 16 of attachment can retract from external covering part 22, allows external covering part
It is maintained between each claw 58.
Interior shield 24 is attached to needle interface 16 when separating with external covering part to cover casing 20.Then delivery pen is inserted
Enter into extractor 130 (as shown in Figure 10 and 11), wherein interior shield 24 passes through longitudinal slit 142, so that edge
154 and tip 150 engage interior shield outer surface with grasp interior shield and resist move up.The delivery pen then can
