Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content for having read instruction of the present invention, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As Figure 1-3, embodiments of the present invention are related to a kind of vehicle-mounted child constrained system test tool coiler,
Including support and main shaft 5, the described level of main shaft 5 is erected on support, and one end of the main shaft 5 passes through bearing 4 and the phase of worm gear 1
Even, the upper end cross of the worm gear 1 engagement that interlocks is disposed with worm shaft 2, and the side of described worm gear 1 is axially extended along main shaft 5
There is connecting plate 12, one end of the connecting plate 12 is vertically provided with flexible connection post 3, and one end of the flexible connection post 3 is inserted radially into
To in the one end of main shaft 5, the other end of described main shaft 5 is provided with handle I 6, and one end of described worm gear 1 is provided with handle II
15, the middle part of described main shaft 5 is disposed with safety belt around socket part 13.
As a kind of embodiment of the invention, with Worm and worm-wheel gearing as governor motion, carry out in two steps：
First, under belt slack state, it is flexibly connected post 3 and is not inserted into main shaft 5, transmission mechanism and the main shaft 5 of such worm and gear
Separate, main shaft 5 will not be driven to rotate, by safety belt around safety belt is connected in socket part 13, handle I 6 can faster by safety
Band winding, so as to " disadvantage " that overcomes worm gear transmission ratio excessive, improves winding efficiency on main shaft 5；Second, safety belt is opened
