Abstract

The utility model relates to a rotary controller arranged on a spanner opening of a hand tool. The spanner opening is provided with through holes which are mutually communicated, and a clamping block and a spring are respectively arranged on both sides of the inner part of each of the holes. A starter head which is extended into the spanner opening is clamped by the clamping block so that the clamping block has the functions of controlling a starter to positively rotate and reversely rotate. The rotary controller can be used for a sleeve barrel, a screw starter, a ratchet spanner and a spanner sheet spanner.

Description

Hand-held tool is located at the rotating control assembly of pulling mouth

The utility model relates to a kind of hand-held tool and is located at the rotating control assembly of pulling mouth.

Wrench has many types, such as open-end wrench, box spanner, ratchet spanner or the like; Wherein, it is the device with one-way brake that a kind of spanner is arranged, as shown in Figure 7, the head 70 of spanner one end is pivoted with a ratchet 71 in inside, head 70 relative ratchet 71 1 sides be oblique dispose a tool flank of tooth support piece 72, supporting piece 72 opposite sides is to be spring 73 elasticity backups, to be meshing with each other with corresponding ratchet 71 by the flank of tooth that supports piece 72, compress by ratchet 71 is rotated counterclockwise to piece 72, spring 73 and can rotate smoothly, on the contrary, turn clockwise, then can't be rotated, therefore the effect of one-way brake is provided to piece 72 embedding systems.But the brake apparatus of aforementioned ratchet spanner is made the element complexity, especially needs to make ratchet 71, and the tool flank of tooth support piece 72, make processing cost increase, assembling is also inconvenient, simplify inadequately.

The rotating control assembly that the purpose of this utility model is to provide a kind of hand-held tool to be located at pulls mouthful makes the device of this control direction of rotation, element processing and manufacturing simple, effectively reduces manufacturing cost, and result of use is good.

For achieving the above object, the rotating control assembly that the utility model provides a kind of hand-held tool to be located to pull mouthful, this hand-held tool at one end is provided with a main body, it is characterized in that: this main body is provided with one in central authorities and pulls mouth, in main body relatively this side of pulling mouthful laterally be provided with at least one with pull a mouthful through hole that communicates, and be provided with a clamping block, a spring in regular turn in this through hole, this clamping block one side is to be exposed to pull a mouthful inside.

Described hand-held tool is located at the rotating control assembly of pulling mouthful, it is characterized in that: in this through hole, in the open end plug one lid that compresses spring is housed.

Described hand-held tool is located at the rotating control assembly of pulling mouth, it is characterized in that: a main body is provided with one in central authorities and pulls mouth, pull mouthful both sides with respect to this and be drilled with a through hole, and in this through hole, be provided with a clamping block, a spring and a part of pulling from inside to outside in regular turn, enclose the flexible steel ring that can touch the part outside of pulling with one in the main body outer circumferential side, this flexible steel ring outside is corresponding pulls part and evagination has the protuberance of round, is made as the pull accommodation space of part of blocking in the protuberance.

In sum, the utility model possesses following advantage:

The utility model possesses simple and easy, the easily manufactured effect of processing, and because of such as part or the clamping block of pulling, its form is processed very simple, with low cost, can effectively improve traditional use shortcoming; And the utility model also can apply to multiple hand-held tool form, and as ratchet spanner, sheet ratchet spanner, screwdriver etc., the scope of application is extensive.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.

Brief Description Of Drawings:

Fig. 1 is an element of the present utility model plane decomposing schematic representation.

Fig. 2 is the 2-2 generalized section of the utility model such as Fig. 1.

Fig. 3 is applicable to the embodiment floor map of bottle opener for the utility model.

Fig. 4 is the 4-4 generalized section of the utility model such as Fig. 3.

Fig. 5 is applicable to the embodiment floor map of ratchet spanner for the utility model.

Fig. 6 is the another kind of embodiment floor map of the utility model.

Fig. 7 is traditional part plan generalized section.

As Fig. 1, shown in 2, if the main body 1 of a hollow cylinder shape, what it respectively was formed with different apertures at two ends pulls mouthfuls 11, main body 1 is being to be drilled with one to communicate and pull mouthfuls 11 through hole 12 perpendicular to pulling mouthful 11 axial positions relatively, and be separately installed with a clamping block 13 in regular turn in the both sides of through hole 12 inside, the part 15 of pulling of one spring 14 and a steel ball shape, the relative through hole 12 of main body 1 outer circumferential side, be to enclose to entangle a flexible steel ring 16, corresponding the pulling part 15 of each steel ball shape in this flexible steel ring 16 outsides and be provided with the protuberance 161 of evagination round can contact at wherein flexible steel ring 16 for the part 15 of pulling;

Therefore the utility model can this main body 1 of mat utilize pull mouthfuls 11 form forward and backwards to control action, promptly after mouth 11 is pulled in the insertion of screwdriver head 20 1 ends, rotate towards a direction, one of this direction part 15 of pulling is born against in the protuberance 161 of this side, the part 15 of pulling of opposite side is not because enter in the protuberance 161, clamping block 13 is born against relatively at the screwdriver head of pulling in mouthfuls 11 20, can't not enter a sideway swivel in the protuberance 161 towards this part 15 of pulling, can only enter a sideway swivel in the protuberance 161 towards the part 15 of pulling, the effect of the unidirectional rotation of control is provided.

Next, the utility model can be applied in the hand-held tool of many types, and as Fig. 3, the 4th, for being applied in the embodiment of screwdriver 21, the screwdriver head 22 of screwdriver 21 is that plug-in mounting goes into to pull in the mouth 11.

In addition, this is pulled mouthful 11 an interior clamping block 13 and springs 14 and both can be provided with the upper and lower position, can also independent one group of existence, also or, clamping block 131 is the post bulk to replace, in the lateral attitude of the relative blocking screwdriver head 20 of ratchet spanner 23 1 sides shown in Fig. 5 ratchet spanner 23 forms, be pack in regular turn a clamping block 131 and a spring 14, lid 17, locate by clamping block 131 blockings; Or be applied to the ratchet spanner 24 of sheet as shown in Figure 6, side at ratchet spanner 24 is provided with a side opening 240 towards pulling mouthful 241 1 sides, with a clamping block 131, a spring 14 and the lid 17 of packing into according to the order of sequence, this is inserted in the screwdriver head 25 of pulling mouth 241 to utilize clamping block 131 clips.

By aforesaid explanation as can be known, the utility model mainly is at a side of pulling mouthful pack into spring and clamping block, uses simple shape and just can reach the purpose that assembling space is little, processing and manufacturing is easy.
