Description

Many rule ratchet spanner structures

Technical field

The utility model relates to a kind of many rule ratchet spanner structure that has multiple size and can reduce volume, relates in particular to a kind ofly reducing cost, and promotes and uses the many rule ratchet spanner structure that goes up safety.

Background technology

But the ratchet-type spanner is a kind of hand-held tool of movement in one direction, it is to utilize brake [sleeve or actuating strut] after cover is pulled or plugged in the working substance [being nut or bolt or hexagon socket head cap screw] of pulling, selective property is controlled the monolateral action working substance of brake, and locking or the release action that can oppositely dally and return fast, need not stop to take off the problem that engaging is again pulled again for solving conventional spanner, with the simplicity and the speed of promoting this wrench operated.

Concise and to the point formation such as Fig. 1 of aforementioned conventional ratchet-type spanner, shown in Figure 2, it is that at least one end is formed with a head 15 in the two ends of a tommy bar 10, and be provided with a brake 16 that utilizes one-way clutch assembly [not shown in the figures] to drive in the head 15, the effect that makes this brake 16 can produce unidirectional drive, establish one again on the head 15 and can control the driving lever 17 that the one-way clutch assembly is controlled brake 16 rotation directions, for the driving direction that changes brake 16, and brake 16 alternatives are nested with the sleeve 20 of the corresponding socket part 21 of a tool, and different sleeves 20 can have the fit portion 22 of different size specification, this fit portion 22 is used for overlapping the working substance of pulling, locking of selective property or release working substance;

And this ratchet spanner cooperates the sleeve 20 of a plurality of different size specifications to be formed by single tommy bar 10, that is to say that sleeve 20 is the single size specification, so when in use running into the working substance of different size specification, the user promptly need change the sleeve 20 of correspondingly-sized, therefore the staff need carry the sleeve 20 of various different size specifications, and more need cooperating thing size constantly to change at work, invisible promptly increases number of times and the time of changing, and causes the inconvenience and the slow-footed problem of use;

Moreover, fit portion 22 axis of existing sleeve 20 and its socket part 21 axis are with online always, not only invisible has been limited the possibility that sleeve 20 can be designed to many specifications of tool fit portion 22, brake 16 forms the L bar with the whole protrusion tommy bar 10 of the length of sleeve 20 additions, so not only can't effectively reduce volume, cause the inconvenience of taking in and transporting, and in use, also easy brake 16 and sleeve 20 because of exposing, and the problem of improper collision takes place, invisible influences the convenience that uses, and has the misgivings of security;

Therefore, existing ratchet spanner has been subjected to the restriction of structure, cause its sleeve amount of carrying many, and need the constantly problem of replacing, need inconvenience especially when eminence is worked when running into the staff, so if can allow ratchet spanner have the design of the many rule of one, believe to have concurrently and use effect quick and facility, and can satisfy reduced volume and demand safe in utilization.

In view of this, this creator is by the experience of being engaged in research and development for many years, the problem that is faced in the use at aforementioned ratchet spanner, actively seek solution, research through constantly making great efforts with study, finally success develop a kind of many rule ratchet spanner structures, it overcomes existing ratchet spanner can't have many rule and little inconvenience that causes of volume and puzzlement concurrently.

The utility model content

Technical problem underlying to be solved in the utility model is, overcomes the above-mentioned defective that prior art exists, and a kind of many rule ratchet spanner structures are provided, and so as to changing the size of different size fast, and can have concurrently to promote and operates effect easily; It can dwindle the volume of overall appearance, promoting portable and the convenience of taking in, and can promote the security in the use.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of many rule ratchet spanner structures is characterized in that, are that at least one end is formed with a head in the two ends of a tommy bar, and are provided with one in the head for driving the socket group that working substance rotates, and are provided with the group of alloting that an optional dial sleeve connects group unidirectional drive direction again in the head; Described socket group is located at the institute that turns that ratchet and in the head is located in the ratchet by one and is formed, wherein the ratchet center is formed with the groove of wearing that a both sides tool holds portion relatively, turn again and can in ratchet, pivot, and the rotation that order is turned and the pivot center of socket group ratchet are the vertical interlaced shape, moreover the periphery of turning is formed with one or more fit portion vertical with rotation.

Aforesaid many rule ratchet spanner structures, wherein being formed with one in each head of tommy bar supplies group to establish the race of socket group, and each head one side is formed with one in addition and is communicated with race and establishes the allocating slot of alloting group for group, and race and allocating slot apical margin are covered with one and utilize the C type to buckle the cover plate of clip again.

Aforesaid many rule ratchet spanner structures, the ratchet two of wherein socket group holds and is formed with relative axial trough in the portion respectively, and the both side surface of turning is formed with the axial region of corresponding axial trough respectively.

Aforesaid many rule ratchet spanner structures, the ratchet of the wherein socket group wherein portion of holding is formed with one or more containing hole on corresponding rotor surface, each containing hole is respectively equipped with one and can turns relatively and produce the elastic spacing one of restriction, is formed with the stopper slot of one or more corresponding elastic spacing one and turn on corresponding wall.

Aforesaid many rule ratchet spanner structures, wherein alloting group is made of a sour jujube piece of being located in the head, the sour jujube piece is formed with one first ratchet part and one second ratchet part respectively in an end of corresponding ratchet periphery, and the sour jujube piece is one first locating slot and one second locating slot of first and second ratchet part of end formation correspondence respectively in addition, be provided with in the head again one relatively the sour jujube piece produce the flexible positioning piece of position-limiting action, allot group again and have a plectrum that passes head.

Aforesaid many rule ratchet spanner structures, wherein allot group and have the two sour jujube pieces that are hubbed in the head, and an end of the corresponding ratchet periphery of two sour jujube pieces has a ratchet part respectively, allot the outside and the head inner edge organized in each sour jujube piece again and be arranged with an elastic component, moreover allot to organize and in head, be provided with the pushing and pressing part that an alternative presses the sour jujube piece, and allot to organize and be provided with a plectrum that can move this pushing and pressing part in head.

The beneficial effects of the utility model are, specific implementation by the utility model aforementioned techniques means, allow sleeve of the present utility model have the design of the many rule of one, make the user directly turn according to different demands, to select the fit portion of different size specification for use, the amount of carrying of sleeve in the time of so can significantly reducing work, and can promote the speed of changing, simultaneously because the utility model ratchet spanner has more the characteristic of unidirectional drive, selective property driving locking or loosen working substance, the utility model can be had concurrently use fast and the effect of facility, simultaneously can effectively dwindle the volume of overall appearance, promote its portable and the convenience of taking in, thereby promote the security that it uses, supplying significantly increases its surcharge, and improves its economic benefit.
