The course of work of the present utility model and principle:
What the utility model provided mainly cooperates the spanner that forms by band gear adapter head 1, commutation pin 3, compression spring 6 and reversing handle 7, can by reversing handle 7 and the commutation pin 3 of fixedlying connected with it make spanner turn clockwise work, be rotated counterclockwise slippage, or be rotated counterclockwise work, slippage turns clockwise.Band gear adapter head 1 can only unidirectionally rotate under the control of commutation pin 3, and cylindroid helical-coil compression spring 6 provides kinetic energy for commutation pin 3.As shown in Figure 4, when pulling operating grip 41 cylindrical shape geared sleeve 4 turned clockwise, commutation pin 3 is under the effect of compression spring 6, make cylinder commutation 31 end of commutation pin 3 insert gear tooth slot 15, because but cylinder commutation head inserts the right angle recess 32 that top one side of teeth groove 15 is provided with block gear one flank of tooth 13, opposite side is provided with the chamfering inclined-plane 33 on the top rib that is overlapped on another flank of tooth 14 of the flank of tooth 13 in same teeth groove, here the flank of tooth 13 is working faces of strength of gear, the flank of tooth 14 is a slip plane, at this moment, band gear adapter head 1 does not have relative motion with cylindrical shape geared sleeve 4, spanner is in running order, band gear adapter head 1 will rotate with cylindrical shape geared sleeve 4, rotate thereby drive threaded connector.As shown in Figure 5, when pulling operating grip 41 cylindrical shape geared sleeve 4 be rotated counterclockwise, the slippage from the top rib of the flank of tooth 14 of the chamfering inclined-plane 33 of commutation pin 3 by cylinder commutation 31 is lifted, move and be position shown in Figure 5, at this moment, band gear adapter head 1 is done relative motion with cylindrical shape geared sleeve 4, and the gear slippage realizes that returning of spanner is sliding.
If the oppositely operation of loading and unloading threaded connector, as long as the pin 3 that will commutate is mentioned afterwards Rotate 180 °, as shown in Figure 6, the flank of tooth 14 is converted to working face in the teeth groove 15 of gear 12.When pulling operating grip 41 cylindrical shape geared sleeve 4 is rotated counterclockwise, identical with above-mentioned operation principle, different is that the threaded connector direction of rotation that is applied is opposite.The end of operating grip can be connected with mechanical device, as hydraulic means etc., substitutes the part manpower with mechanical device, and it is more convenient to work, and efficient further improves.
In sum, in loading and unloading during threaded connector, no matter machinery or manpower as long as pull operating grip, just band gear adapter head 1 is synchronized with the movement with cylindrical shape geared sleeve 4, are necessarily finished loading onto or unloading of threaded connector in the rotation angle range.The anglec of rotation of above-mentioned wrench operated handle 41 is decided by working environment and condition of work, and rotation angle range is not limit.
Fig. 7 is that two commutation pin types are capable of reversing, time sliding continuous operation wrench is rotated counterclockwise the structural representation under the duty.The difference capable of reversing to the pin type, that return sliding continuous operation wrench of the monodromy of present embodiment and embodiment 1 only is to be provided with two groups of commutating structures that are made of commutation pin 31, the cylindrical shape guide 5 that is provided with locating notch 51 and spacing dividing plate 52, compression spring 6 and reversing handle 7, and its operation principle and other structure are all identical with embodiment 1.This does not give unnecessary details.Adopt two commutating structures, can make spanner bigger to the application of force intensity of gear 12, it is more reliable and more stable to work.
The above only is a preferred embodiment of the present utility model, is not shape material of the present utility model and structure are done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
