Wherein, the top shape of backhaul control head 31 may be configured as deviating from last tooth towards tooth close to triangle
The side of proximal end is inclined-plane, and the inclined-plane, towards last tooth inclination, inclination angle alpha controls head 31 in the backhaul no more than 30 °
Top formed h difference in height；It is essentially vertical plane towards the side of last tooth.Backhaul controls the position of head, along rack gear length
Direction, when backhaul control head is in first state, end face gram has part that should enter between the backlash of gear thereon, it is preferred that
Its height for entering gear teeth tip circle is the modulus of gear not less than 0.03M(M).The mistake that the gear 1 is rotated in a first direction
The upper surface of Cheng Zhong, the distal ends 33 of 1 gear teeth of gear and backhaul control head 31 is tangent, each gear teeth sequentially head is controlled by backhaul
31 upper surface lower positions gradually slide into backhaul control 31 upper surface higher position of head, and each gear teeth drive the backhaul control repeatedly
Head 31 processed is downwards.Gear is disengaged from as a result, dallies on backhaul control head 31, and opposite rack gear is without obvious displacement, i.e., in fact
Now to the positioning of rack gear, rack gear opposed gear is limited in the position of corresponding backhaul control head 31.
In Fig. 3, along 2 width direction of rack gear, backhaul control head 31 can be threaded through in rack gear width regions.Certainly, backhaul control
Head 31 processed may also be arranged on rack gear side.Alternatively, if the equivalent width of gear, rack gear, it can also be along rack gear length side
The band of position that head is controlled to setting backhaul sets relatively narrow compared to gear width for the width of rack gear, and backhaul control head is made to begin
Eventually in gear width range in, with sufficiently in Gear Contact have an effect realize two states between switching.
In Fig. 3, the both ends of the rack gear 2 are respectively arranged with 2 floating return facilities 3,2 floating backhaul dress
3 symmetrical configurations are set, can be respectively that the rack gear 2 provides the positioning of both direction, limit the relatively described rack gear of the gear 2
It is moved between a floating return facilities 3.
By taking Fig. 4 or Fig. 5 as an example, state may be arranged as being integrally formed between elastic component and backhaul control head 31.Institute
The one end for stating elastic component can connect inner wall, side wall or the top of the rack gear 2, and the other end of the elastic component connects the backhaul
Control head 31.
Specifically, 2 top of rack gear hollows out to form the backhaul control head 31, described under the implementation of Fig. 4
Elastic component is a cantilever 35, and one end of the cantilever 35 is connected with the top of the rack gear 2,35 other end of cantilever and
The backhaul control head 31 is connected, and the backhaul controls the relatively described rack gear under the elastic reaction of the cantilever 35 of head 31
Engaging tooth where plane float up and down.
And under another implementation shown in Fig. 5, the elastic component equally may be configured as a cantilever 35.The cantilever 35
One end and the side wall of the rack gear 2 are fixed, and the other end of the cantilever 35 is connect with the side of backhaul control head 31.The reality
Backhaul control head, cantilever under existing mode are not to hollow out and formed on rack gear, are external components, spring can be used in cantilever 35
Steel wire.The backhaul control head 31 is under the elastic reaction of the cantilever 35 where the engaging tooth of the relatively described rack gear above and below plane
It floats.
Gear rotates clockwise, and rack gear is to left, and when wheel and rack is transferred to backhaul point, gear is nibbled with last tooth disengaging
After conjunction, the locating slot on right side has been entered.At this point, rack gear cannot continue to left but stop in time in backhaul point.At this point,
Even if motor works on band, moving gear continues to rotate clockwise, but dallies since gear remains in locating slot, with
No engaged transmission between rack gear, thus, rack gear is also to rest on original position always in backhaul point.Thus this programme is realized quasi-
Determine position.Since backhaul control head can float downwards, gear will not be hindered to enter locating slot, gear enters positioning
After in slot, backhaul control head be in pressed status or it is critical be in free state.As shown in Fig. 2, when needing backhaul, gear by
It drives to motor, is rotated counterclockwise from the locating slot on right side, when the upper surface of some tooth of gear and backhaul control head, which is supported, closes,
Then gear mesh rack gear generates thrust to the right, and rack gear is promoted to generate lesser displacement to the right, due to the upper end of backhaul control head 31
Face, which enters, has certain height between the backlash of gear, therefore is able to satisfy such thrust, while backhaul control head 31
Upper surface and close to vertical side also to gear generate support force to the left promote the engaging tooth on wheel and rack into
One step forms engagement then continuous transmission, and rack gear continues to right translation, to form reciprocal transmission.The side close to vertical plane,
Can form good thrust and support force, and the another side of backhaul control head 31 towards the proximal end of rack gear diagonally downward, can reduce
The suffered resistance of gear idle running.
The above is only embodiments of the present invention, and the description thereof is more specific and detailed, and but it cannot be understood as right
The limitation of the invention patent range.It should be pointed out that for those of ordinary skill in the art, not departing from the present invention
