Description
Technical field
The utility model relates to a kind of control positioner, particularly a kind of ratchet spanner that is used for the control positioner of ratchet spanner and comprises it.
Background technology
Extremely shown in Figure 15 as Figure 11, dialled control formula ratchet spanner 50 structurally mainly is to be provided with a holding part 52 at drive division 51 in the past, the inboard rear end of holding part 52 then has the slot part 53 of pulling of putting of a connection, the rear end of putting the slot part 53 of pulling is communicated with a control button slot part 54, be provided with a post hole 55 and shrinkage pool 56 and dig in the control button slot part 54, be provided with a spacing steel ball 57 in this shrinkage pool 56; And can establish an actuator 60 with ratchet 61 for card in this holding part 52, be provided with two brake blocks 70 that correspondence is reverse in the slot part 53 of pulling and put, the front end face of those brake blocks 70 is latch 72 structures, can with ratchet 61 clamping mutually of actuator 60, and the upper surface of those brake blocks 70 all is provided with a controlled post 71, and these 70 of two brake blocks are equiped with an elastic component 73; Can plug a direction control knob 80 in this control button slot part 54, front end at these direction control knob 80 downsides is provided with the control portion 81 of dialling, and be provided with a reference column 82 and a spacing groove 83 in its back-end, and this reference column 82 is inserted in the post hole 55 of control button slot part 54, forms the axis of rotation of direction control knob 80 according to this.
Like this, pass through said structure, after direction control knob 80 changes toward a lateral deviation, this direction control knob 80 can be by spacing groove 83 and spacing steel ball 57 clampings location, and this group control portion 81 collude prop up its front end brake block 70 be subjected to reversed column 71, make the ratchet 61 of the latch 72 disengaging actuators 60 of this brake block 70, and make brake block 70 forward end and the drive division 60 of the other end push against by pushing of elastic component 73, and then form unidirectional spine move state, therefore utilize the change of 80 groups of veers of direction control knob, can reach the conversion of spine move direction.
Though ratchet commonly used is dialled the effect that the control design can reach two-way switching, on reality is used or made, have many shortcomings really, be described as follows:
One in order to prevent the disengaging of this direction control knob, therefore need give spacingly by the structure that is inserted in control button slot part, but this kind structure will increase the difficulty when making, and then produces the shortcoming that raises the cost or add man-hour.
They are two years old, because the structural relation of the spinning movement of direction control knob and group control portion and controlled post, make that putting the slot part of pulling must keep activity space (as shown in figure 13) with the overlapping of controlling the button slot part, therefore will cause being provided with of brake block highly to be subjected to a large amount of compressions, and then the clamping area of influence and actuator latch, exist so have the problem of torsion deficiency.
The utility model content
The technical problems to be solved in the utility model is in order to overcome group defective that the control structure existence is used of ratchet spanner in the prior art, a kind of ratchet spanner control location structure to be provided.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of control positioner, it comprises a drive division, one has the actuator of ratchet, one direction control knob and two oppositely corresponding brake blocks, this drive division is provided with a holding part, the inboard rear end of this holding part is provided with the slot part of pulling of putting of a connection, this rear end of putting the slot part of pulling is provided with a limit button slot part, this actuator is arranged in this holding part, this direction control knob is arranged in this limit button slot part, those brake blocks are arranged at this and put in the slot part of pulling, the front end face of those brake blocks has some latches, those latches can with those ratchets clamping mutually of this actuator, its characteristics are:
Each this brake block digs from rear end face and is provided with one and is subjected to dial perforation, this is subjected to dial the inner side end that perforation is through to this brake block, below this of this inner side end is subjected to dial perforation, be provided with a containing hole, and between the relative containing hole of two these brake blocks two, be equiped with one first elastic component;
Dig in this limit button slot part and be provided with a slotted eye, this direction control knob comprises the portion of contracting in the limiting section,, the one group of control portion and a jack-post body, wherein, this jack-post is external to be equipped with one second elastic component and to be inserted in this slotted eye, and this group control portion corresponding inserted is subjected to dial in the perforation in those of those brake blocks of front end.Should in the portion of contracting make this direction control knob when rotary manipulation not with the location overlap that is provided with of those brake blocks.
The utility model changes by this direction control knob dialling in described limit button slot part and switches, those that can make that this group control portion gos deep into those brake blocks that this place ahead fastens are subjected to dial in the perforation, and then pull those brake blocks rear end to the inside and move, and this ratchet of brake block forward end that can be by this elastic member presses other end when those brake blocks move fastens, and then reach the change of spine move direction, and, so can obtain the maximum area clamping state of latch and actuator ratchet because this group control portion is subjected to dial the also latch zone of vacant those brake blocks of perforation with this.
By said structure, this this actuator of direction control knob switch just changes, reverses and fixing multiple use form to produce.This group control portion is subject to being subjected in group perforation of those brake blocks, therefore can avoid this direction control knob to break away from, and this direction control knob upwards supports to arrive in by this second elastic component, thereby reaches the location when dialling the commentaries on classics operation.
Preferably, this first elastic component and/or this second elastic component are a spring.
Preferably, the rear end of each this brake block has an extension, and this is subjected to dial perforation and is arranged at this extension backward and locates, and this group control portion of this direction control knob contracts in the correspondence in the lump.So just can be used in the configuration of the less spanner of volume.
The utility model also provides a kind of ratchet spanner, and its characteristics are that it comprises aforesaid control positioner, and this drive division is arranged on this ratchet spanner.
Positive progressive effect of the present utility model is: the penetration type of control positioner of the present utility model by brake block is subjected to dial perforation and dials penetrating of control portion with the direction control knob and fasten design, and direction control in the portion's structure that contracts, make that the direction control knob will be not when rotary manipulation and the location overlap that is provided with of brake block, said brake block gets final product the complete spatial altitude that utilizes this to put the slot part of pulling, and the ratchet that makes the latch of those brake blocks and actuator reaches the clamping of maximum area, obtains splendid torsion state thus.
