Referring to Fig. 1-Fig. 8, this utility model comprises insulation knob 51, fixture block 52, and locating piece 53, spring 54, pintle hook lock 55, locking positioning pin 526, circulation canal 50 and rotating shaft 45, locating piece 53 is threaded with front hand grip 62.
The centrage of fixture block 52 of the present utility model, locking positioning pin 526 and rotating shaft lockhole 451 is on same axis, and their centrage is vertical with the centrage of rotating shaft 45; Locating piece 53 is fixing with handle 6, and pintle hook lock 55 is socketed on the locating piece 53 and can moves in fixture block 52, and spring 54 is between locating piece 53 and fixture block 52, and fixedly there is insulation knob 51 upper end of fixture block 52.
The middle part of fixture block 52 of the present utility model is provided with a circulation canal 50, and the motion of pintle hook lock 55 in this circulation canal 50 is unidirectional shuttling movement; In the present embodiment, circulation canal 50 has five positions, channel position 1 is initial position, channel position 2 522 is a updip loxosis, then, channel position 2 522 both by a downward step to channel position 3 523, it is downward step site successively that channel position 3 523, channel position 4 524, channel position 5 525 are respectively, wherein channel position 5 525 is updip loxosises, its terminal upper surface is higher than the upper surface of channel position 1, make pintle hook lock 55 in this circulation canal 50, make unidirectional shuttling movement, adverse movement can not occur.
Rotating shaft 45 of the present utility model is fixed and is sleeved in the attaching nut 48 with central siphon 47, rotating shaft lockhole 451 is distributed on the head of rotating shaft 45 small ends 450 and is positioned on the circumference of rotating shaft 45, rotating shaft lockhole 451 is blind hole in the present embodiment, and rotating shaft lockhole 451 has six, in order to the quantity in hole is reached at most, increases latched position thus.In actual the use, latched position is The more the better; Six rotating shaft lockholes 451 in the present embodiment can satisfy the requirement of locking claw beam.
The self-locking of this utility model energy can be controlled 360 ° of rotations of claw beam I, adjusting rotating mechanism 4.
Operation principle of the present utility model is: the coupling of the rotating shaft lockhole 451 of six diverse locations realizes locking on the locking positioning pin 526 by fixture block 52 and rotating shaft 45 circumference.Namely when locking positioning pin 526 separates with rotating shaft lockhole 451, the claw beam I, regulating rotating mechanism 4 can 360 ° of rotation; When locking positioning pin 526 inserted rotating shaft lockhole 451, claw beam I, adjusting rotating mechanism 4 can not rotate.So locking mechanism 5 realizes locking work by two different positions up and down of fixture block 52, and two diverse locations of fixture block 52 are controlled by pintle hook lock 55.
Because the motion of pintle hook lock 55 in fixture block 52 circulates; When pintle hook lock 55 during in channel position one 521 positions, locking positioning pin 526 separates with rotating shaft lockhole 451; When pintle hook lock 55 during in channel position 4 524 positions, locking positioning pin 526 inserts rotating shaft lockholes 451.
During use, pintle hook lock 55 is initial position in the position of channel position 1, claw beam I, 360 ° of rotations of adjusting rotating mechanism 4 energy, click insulation knob 51 again, pintle hook lock 55 arrives channel position 4 524 from channel position 1 through channel position 2 522, channel position 3 523, and be parked in channel position 4 524, and at this moment locking positioning pin 526 inserts rotating shaft lockhole 451, and claw beam I, adjusting rotating mechanism 4 can not rotate; As want to allow claw beam I, adjusting rotating mechanism 4 rotate, click insulation knob 51 again, pintle hook lock 55 arrives channel position 1 from channel position 4 524 through channel position 5 525, and be parked in channel position 1, at this moment locking positioning pin 526 separates with rotating shaft lockhole 451, and claw beam I, adjusting rotating mechanism 4 can rotate.
Below only be a specific embodiment described in this description, allly conceive equivalence or the simple change that described structure, feature and material are done according to this utility model patent, be included in the protection domain of this utility model patent.
