The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
To shown in Figure 6, what present embodiment was described can singlehandedly control the ratchet spanner that commutates, and comprises as Fig. 1:
One tool heads 10, ratchet with a circular hole aspect holds hole 11, this ratchet holds hole 11 and is communicated with the sour jujube piece tank 12 of offering an arc, and these sour jujube piece tank 12 connections are offered an extension bar group and established hole 13, and this extension bar group is established adjoining this sour jujube piece tank 12 of hole 13 inner edges internal thread 131 is set;
One ratchet 20, the ratchet that is placed in this tool heads 10 holds in the hole 11, and these ratchet 20 outer peripheral edges have plural ratchet 21, and this ratchet 20 has a hexagonal through hole 22 and is provided with driving working substance;
One sour jujube piece 30, be placed in the sour jujube piece tank 12 of this tool heads 10, one side of this sour jujube piece 30 has plural ratchet 31, opposite side then has a depressed part 32 and a pushed part 33, this depressed part 32 is scalariform with this pushed part 33, and this depressed part 32 is separated a limited impression 321 is set, the ratchet 31 of this sour jujube piece 30 is meshing with each other with the ratchet 21 of this ratchet 20, and have a back-moving spring 34 to be arranged in the limited impression 321 of depressed part 32 of this sour jujube piece 30, and make the two ends of this back-moving spring 34 be resisted against the cell wall of this sour jujube piece 30 and this sour jujube piece tank 12 respectively;
One extension bar 40, one end has external screw thread 41 and cooperates the extension bar group that is locked on this tool heads 10 to establish hole 13, and this extension bar 40 wears a push rod tank 42 by this end with external screw thread 41, and this push rod tank 42 has an export 421, and this push rod tank 42 is communicated with and offers a chute 43;
One push rod 50, one end is a pushing and pressing end 51, the other end is sheathed end 52, these pushing and pressing end 51 external diameters are greater than these sheathed end 52 external diameters, and make that formation one pushes away face 53 between this pushing and pressing end 51 and this sheathed end 52, and offer a locating hole 54 on this push rod 50, this push rod 50 is placed in the push rod tank 42 of this extension bar 40, and the pushing and pressing end 51 of this push rod 50 is passed and this sour jujube piece 30 of contact by the export 421 of this extension bar 40, and have a push rod spring 55 to be sheathed on the sheathed end 52 of this push rod 50 and to abut against this to push away face 53, then this push rod 50 pushes away face 53 these push rod springs 55 of pushing and pressing elastic displacement in the push rod tank 42 of this extension bar 40 by this;
One control handle 60, hollow structure, this control handle 60 has a locating hole 61, this control handle 60 is sheathed on outside this extension bar 40, and the locating hole 61 of this control handle 60 is connected with the locating hole 54 of the chute 43 of this extension bar 40 and push rod 50, and run through the locating hole 61 of this control handle 60, the chute 43 of extension bar 40 and the locating hole 54 of this push rod 50 with an alignment pin 62, make this control handle 60 and this extension bar 40 and push rod 50 location and energy interlock, pass this control handle 60 and just can drive the slippage in the chute 43 of this extension bar 40 of this alignment pin 62 synchronously; And
One lever 70 has an extension bar locating hole 71, and the other end that this extension bar 40 connects this tool heads 10 is planted and is positioned this extension bar locating hole 71.
More than for this creation can singlehanded control commutation the structural relation of ratchet spanner, under normal situation, this push rod 50 is subjected to these push rod spring 55 pushing tows and these pushing and pressing end 51 normalities is passed by the export 421 of this extension bar 40, after passing, the pushing and pressing end 51 of this push rod 50 is resisted against the pushed part 33 of the sour jujube piece 30 in this tool heads 10, and make this sour jujube piece 30 be subjected to ratchet 21 engagements of ratchet 31 and this ratchet 20 of a side of pushing tow, shown in the 4th figure, when only part and 20 engagements of this ratchet of the ratchet 31 of this sour jujube piece 30, then drive this ratchet 20 clockwise and just can produce torsion output carrying out work, otherwise, 20 these ratchets of this ratchet 20 of tending to act counterclockwise dally, and carry out the action of switching back and forth fast with this for the user.
And when the user will change ratchet 20 driving directions of outputting torsion, just at last in the process of work, do not need this tool heads 10 is left working substance, shown in the 4th to 6 figure, user X can be gripped on thumb and forefinger on this control handle 60, other three fingers then are gripped on this lever 70, in the time will carrying out the conversion of driving direction, as long as this control handle 60 is passed to lever 70 directions with thumb and forefinger, so this control handle 60 is with regard to energy this alignment pin 62 of interlock and this push rod 50, this alignment pin 62 is in chute 43 slippages of this extension bar 40, these push rod 50 these push rod springs 55 of compression carry out displacement, and the pushing and pressing end 51 that makes this push rod 50 is also by export 421 retractions of this extension bar 40, so this sour jujube piece 30 is disappeared by the strength of pushing tow, user X just can directly grip this lever 70 and pivot, shown in the 6th figure, then the sour jujube piece 30 in this tool heads 10 will change in the position of this sour jujube piece tank 12, so just can control this sour jujube piece 30 and these ratchet 20 position engaged, and then reach the purpose of driving direction conversion, after the action of conversion driving direction is finished, as long as decontrol this control handle 60, the push rod spring 52 of this push rod 50 resets, and makes the return to normal blocking state of this briquetting 30 of contact of this push rod 50.
The through hole 22 of described ratchet 20 also can be quincunx aspect simultaneously, is suitable for other working substance form by this.
From the above, even in the course of the work, do not need tool heads 10 is left working substance, the singlehanded operation that just can carry out the driving direction conversion of user X, convenient in the extreme in the use, and can also reduce tool heads 10 is left working substance time of fit working substance again, increase the smooth degree of work, increase work efficiency.
