Pawl 34 respectively from different tooth engagements, for make the ratchet 40 rotate.
When installation, cam 20 is rotatably mounted to holder 10 by shaft 22, and the swing rod 30 is rotatably mounted to holder
10 the first fixing axle 12 and with the circumference contact of cam 20, the ratchet 40 is rotatably mounted to described the second of holder 10
Fixing axle 14 and the tooth engagement for making one in first pawl 32 and second pawl 34 and the ratchet 40, the bullet
Property element 50 one end be fixedly connected with the swing rod 30, the other end of the elastic element 50 and the holder 10, which are fixed, to be connected
It connects, to which holder 10, cam 20, swing rod 30, ratchet 40 and elastic element 50 are just assembled into threaded fastening device 100.
In use, driving structure drives shaft 22 to rotate, cam 20 is rotated together with shaft 22, and swing rod 30 is in cam 20
Drive lower swing, first pawl 32 and second pawl 34 of swing rod 30 with swing rod 30 swing alternately and the spine
40 engagement of wheel pushes ratchet 40 to rotate, because the head of fixing piece is contained in the receiving portion 42 of ratchet 40, to which fixing piece is with ratchet
40 rotate together and lock.
When cam 20 turns to projection portion, the first pawl 32 on swing rod 30 pushes ratchet 40 to rotate, when cam 20
When being rotated further, the pulling force of elastic element 50 makes the second pawl 34 of swing rod 30 that ratchet 40 be pushed to turn in the same direction, thus
The lasting rotation for ensureing ratchet 40, makes fixing piece lock.In other words, because the effect of cam 20 and elastic element 50 makes ratchet
40 can ceaselessly continue to rotate, to after the terminal operation for completing a fixing piece, continue to next fixing piece
Fastening, i.e. threaded fastening device 100 of the invention can be operated ceaselessly, substantially increase production efficiency.
Specifically, holder 10 of the invention is installed on production line, such as the assembling line of lamp housing and light cover, a fixing piece
Head, such as screw for being fixedly connected with lamp housing and light cover, are contained in the receiving portion 42 of ratchet 40, and driving structure drives shaft 22
It goes to, cam 20 rotates together with shaft 22 and swing rod 30 is driven to swing, first pawl 32 of swing rod 30 and described second
Pawl 34 alternately engage with the ratchet 40 with the swing of swing rod 30 and pushes the rotation of ratchet 40, and fixing piece is with 40 turns of ratchet
It moves and locks, then next receiving portion 42 for needing the head for the fixing piece being locked to be contained in ratchet 40, and so on, i.e.,
The present invention threaded fastening device 100 can be one by one the part that is locked, to substantially increase production efficiency.Together
When, because the present invention utilizes threaded fastening device 100 instead of operating personnel, cost of labor is greatly reduced, to reduce dress
With cost, that is, reduce production cost.
In the present invention, lamp housing and light cover are only to assemble object, and threaded fastening device 100 of the invention is used in lamp housing
Installation between light cover but not limited to this.Certainly, threaded fastening device 100 of the invention is equally applicable to other needs
Using screw or the fixed component of bolt, as lamps and lanterns driver and shell between installation.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
