Abstract

A transmission and positioning mechanism includes a guiding assembly, a driving assembly and a positioning assembly. The guiding assembly includes two sliding rails, a transmission belt, a plurality of sliding members. The sliding members are slidably disposed on the sliding rails. The positioning assembly includes a transmission rod, a positioning rod connected to the transmission rod, a positioning block sleeved on the positioning rod, a driving rod sleeved on the transmission rod. The driving rod defines a spiral slots and at least one limiting slot. The driving assembly is connected to the positioning assembly and rotates the transmission rod, the positioning rod and the driving rod, the spiral slot engages one of the plurality of the sliding members to move other sliding members to the at least one limiting slot and the positioning blocks, and the at least one limiting slot and the positioning blocks latch the sliding members.

Dependent claims

A transmission and positioning mechanism comprising:

a guiding assembly having:
two parallel sliding rails;
a transmission belt loop disposed substantially between the two sliding rails;
and
a plurality of sliding members slidably disposed on the sliding rails;
a first driving assembly;
and
a positioning assembly connected to the first driving assembly, the positioning assembly having:
a driving rod defining an exterior surface and a spiral slot defined in the exterior surface and having at least one slot end, and the driving rod having at least one limiting slot communicating with the at least one slot end;
a transmission rod extending coaxially through, and being coupled with the driving rod;
at least one positioning block;
and
a positioning rod connected to, and rotatable with the transmission rod, the positioning rod extending coaxially through, and being coupled with the at least one positioning block;
wherein, when the first driving assembly rotates the transmission rod and the positioning rod, the spiral slot engages at least one of the plurality of sliding members to move the engaged sliding member to drive the transmission belt to move other sliding members, the at least one limiting slot and the positioning blocks are configured to latch the other sliding members.
