Change handle box be difficult to engage with it is stagnant when problem, keep handle box print performance stable, reliable, have a wide range of application, install and take out behaviour
Work is very light, convenient, fast and simple in structure, ingenious, and production and processing is easy, at low cost, is conducive to extensive use.
As one preferred embodiment of the utility model, it is described it is left be oriented to slide unit 14 and it is right be oriented to slide unit 15 both ends be equipped with it is convex
The rotation limited section 16 risen；When driving head 2 is fully engaged with drive rod 6, mutually held tightly, the both ends of the bayonet lock 31 are supported respectively
On the rotation limited section 16 of 15 outer end of left guiding slide unit 14 and right guiding slide unit；When drive shaft 3 automatically resets, the bayonet lock
31 both ends are against respectively on the rotation limited section 16 of 15 inner end of left guiding slide unit 14 and right guiding slide unit.In this way, can be to driving
The axial movement of dynamic head 2 and rotary motion range are effectively limited, and avoid causing because being axially moved or rotary motion is excessive
Can not normal print and the problem of equipment damage, performance is more stable, more reliable.
Certainly, the axial movement actuator and spinning reduction actuator can also be other deformable and self-righting
Elastic component, such as：Elastic piece, specifically can be such as：The spinning reduction actuator can also be clockwork spring, outer end and inner end difference
It is connected and fixed, is specifically as follows with geared sleeve 1 and drive shaft 3：Outer end and the geared sleeve or bottom cover 13 of 12 madial wall of inner chamber body connect
Fixation is connect, inner end is connected and fixed with drive shaft 3.The guide frame can also be included 12 inside side walls of cavity setting circle
The left guide chute of arc and right guide chute and the bayonet lock 31；The left guide chute and right guide chute are along drive rod 6
Direction is gradually arranged to external spiral, and with drive shaft 3 be rotation center point-symmetrically, and left guide chute and right guide chute are equal
Can be interior end opening, the closed groove in outer end；When assembling, the both ends end of the bayonet lock 31 is stuck in which can slidably reciprocate respectively
In left guide chute and right guide chute, when driving head 2 is fully engaged with drive rod 6, is mutually held tightly, the two of the bayonet lock 31
End is against respectively on the blind end of left guide chute and right guide chute.
It is described left to be oriented to slide unit 14 and the right slide unit 15 that is oriented in addition, the both ends of the bayonet lock 31 are also provided with gear
Surface is equipped with teeth matched with the gear；When assembling, the gear at 31 both ends of the bayonet lock is led with left guiding slide unit 14 and the right side respectively
Teeth engagement connection on slide unit 15；When powder box installation in use, the drive rod 6 of machine drives with the driving head 2 of drive shaft 3
It connects, drive shaft 3 is driven to rotate, be at the same time axially moved actuator (the spring a 4 of compressive state) and drive drive shaft 3 axial
It moves out, the gear on this process bayonet lock 31 is in left guiding slide unit 14 and the right teeth gear motion being oriented on slide unit 15, directly
It fully contradicts, engage with driving head 2 to drive rod 6, tightly mutually embrace；When drive rod 6 and the driving head 2 of drive shaft 3 divide
From when, 3 automatic reverse of the drive shaft rotate simultaneously move axially inward, realization automatically resets.
Moreover, the actuator that is axially moved can also be elastic supporting bar set on 3 inner end end of drive shaft, when assembling
The elastic supporting bar flexural deformation simultaneously abuts connection with bottom cover 13；When powder box installation in use, the drive rod 6 of machine and drive
The driving head 2 of moving axis 3 is drivingly connected, drive shaft 3 is driven to rotate, and at the same time the restoring force of elastic supporting bar drives drive shaft 3
Axially outward movement, the state for supporting and keeping up make drive rod 6 fully contradict, engage with driving head 2, tightly mutually
It embraces.
