Abstract
The utility model relates to a two function jacking movable spanner, which comprises a movable jaw, a rotary jaw, a worm, a handle body, etc. A rotation shaft is connected with the rotary jaw and the handle body. The upper part of the handle body is provided with a braking button, a reverse drawing torsion spring, a gear fork, and a top fork. The lower part of the handle body is provided with the jack of the rod of a rotary tool and the installation hole of a positioning pin. The utility model is a special purpose hand tool which is used for tightening and loosening threaded fasteners. The utility model also has the functions and the advantages of the rotary tool and is an ideal wrench, with the advantages of continuous and fast operation, synchronous twisting and rotation without clamping a screw nut, high work efficiency, light weight, and novelty.
Description
The utility model relates to a kind of hand tools, be exclusively used in be wrenched and looser a bolt, the adjustable wrench of nut and screw.
Commercially available general utility wrench is when the degree of tightness threaded fastener, and service speed is slow excessively, and living with now " fast pace " is contrary to.Recently the adjustable wrench of prosperousization of Linan, Zhejiang valve plant production and selling, there are return spring and revolution to pull mouth in the head increase, during use, the speed of degree of tightness threaded fastener is accelerated to some extent, but it still dislikes not enough is when the friction that is stuck in nut in pulling mouthful and screw rod is little when arriving to a certain degree, nut tends to rotate synchronously with adjustable wrench, invalid twisting occur, and influences work efficiency.And this adjustable wrench does not have concurrently and revolves the tool function, can not turn screw.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and designs a kind of elasticity bolt, nut fast, and when the friction of nut and screw rod little to a certain degree the time, nut can not rotate with adjustable wrench synchronously yet, invalid twisting can not appear promptly, work efficiency high and have concurrently and revolve the tool function, can turn the difunctional push mode adjustable wrench of screw.
The purpose of this utility model can realize by following measure: it includes the Flexible spanner mouth, mouth and handle body etc. are pulled in revolution, promoting the inside and outside worm screw of moving of Flexible spanner mouth is installed between finger plate mouth and the handle body, revolution is pulled mouth and is connected as a single entity by spanner rotating shaft and handle body, there is revolution to pull a mouthful drag knob on the handle body, in the handle body clip slot return elastic device is arranged, make revolution pull mouth and under no external force situation, automatically reset.Handle body top is blocked the worm screw outer end and inner retaining hairpin and top hairpin is arranged respectively, and handle body longitudinal middle part has the tool of revolving bar jack, and handle body lower, transverse has the tool of revolving bar alignment pin installing hole.
The also available following measure of the purpose of this utility model comes perfect: said return elastic device is good with torsion spring; The honeycomb material-saving is adopted in handle body bottom.
Description of drawings of the present utility model is as follows:
Fig. 1-3 is the utility model structure chart
Fig. 4 is the A-A diagrammatic sketch of Fig. 1
The utility model below in conjunction with examples of implementation to describe in detail: Flexible spanner mouth 9, revolution pull mouthfuls 10, handle body 11 all can forge and form, and be in enormous quantities low-cost, is advisable with hot investment casting especially.But the slotted eye metalworking of above-mentioned parts bores, mill and form.Worm screw 8, bearing pin 5 and 13, torsion spring 12, to revolve tool bar 3 etc. be general part, is commercially available.Surface smoothnesses etc. can be by metalworking and electroplating processes.These all are that the mechanician knows, and do not give unnecessary details for this reason.
It should be noted that the retaining hairpin 7 and top hairpin 6 on handle body 11 tops, they place worm screw 8 outer ends and inner both sides respectively, are the hairpin shape, and retaining hairpin 7 blocks worm screw 8 and do not move outward.Top hairpin 6 is to pull mouth 10 in revolution to do when handle body 11 rotates around spanner rotating shaft 5, must touch worm screw 8 and worm screw 8 is outwards ejected certain distance, thereby make Flexible spanner mouth 9 also outwards shift out certain distance, then the two bayonet socket width increasings of pulling mouthful 9 and 10 card nuts of forming; When the external force disappearance, under the elastic force effect of manual torsion and return torsion spring 12, revolution is pulled mouth 10 when handle body 11 resets, and worm screw 8 breaks away from top hairpins 6, and to its outer top power disappearance, the bayonet socket width returns to position width (being nut two across flats).During use, desire fastening nut, then regulating worm screw 8 earlier makes the bayonet socket width just in time tighten nut two opposite side, change certain distance clockwise, another mistake hour hands rollback, at this moment the friction of nut and screw rod is greater than the elastic force of return torsion spring 12, make revolution pull mouthful 10 rotations of doing from handle body 11, top hairpin 6 outwards pushes up worm screw 8, Flexible spanner mouth 9, and the bayonet socket width is increased to greater than nut diagonal width, and nut is unlikely to be subjected to carrying secretly of bayonet socket and rotates synchronously.Again for the second time clockwise during fastening nut, torsion and return torsion spring 12 elastic force make revolution pull mouthfuls 10 to reset, and worm screw 8 breaks away from top hairpins 6, and top power disappears, and screw rod 8 resets, the width when the bayonet socket width is returned to chucking nut two opposite side, thus tighten certain distance effectively again.And so forth, just can be continuously fastening nut fast, during can not carry that nut rotates synchronously secretly and the phenomenon of taking a lot of work.As unscrewing nut, then push away (turning round) moving drag knob 4, make revolution pull mouthfuls 10 and block and do not rotate, make general utility wrench and use and get final product.
The honeycomb material-saving of handle body 11 Lower Halves, but weight reduction, it is also easy that tool bar jack 2 is revolved in processing.The compression spring should be adorned in alignment pin installing hole 1 bottom of handle body 11 lower, transverse, and " d " font hole is opened at pin 13 middle parts, revolves evolution groove on the tool bar.Built-in when revolving tool bar 3 and will use, only need to press on the other hand alignment pin 13, the hole, garden at this pin middle part is aimed at and is revolved tool bar point, the another hand will revolve tool bar 3 outwards to be transferred to, when this bar square groove is in dowel hole 1, the compression spring blocks alignment pin 13 resiliences and revolves the tool bar, and it is fastening to revolve the tool bar, can turn screw.
This jacking spanners is than prior art, has to turn fast continuously spiral shell The line securing member is when turning back in the other direction. Can not carry nut secretly and do synchronously showing of rotation Resemble, the work efficiency height, light weight, cost are low, and have advantages such as revolving the tool function concurrently.
