Abstract
The invention relates to an open end wrench, comprising a handle and a wrench head which is connected with the handle. The wrench head comprises a fixed clip jaw, an active clip jaw, a neck part whichis connected with the fixed clip jaw and the active clip jaw, an elastic element and a clipping hole. The fixed clip jaw is provided with a fixed clipping surface which faces the clipping hole and extends from the opening of the clipping hole to the neck part, and a concave surface which extends from the fixed clipping surface to the neck part. The active clipping jaw is pivoted at the neck part,and is provided with a thorn block which protrudes from the inside of the clipping hole, a blocking surface which is formed on the thorn block and faces the inside of the clipping hole and presents acorresponding side of the fixed clipping surface, and a pushing surface which extends from the blocking surface and faces the clipping hole opening. The elastic element constantly connects the blocking surface of the thorn block to face to the inside of the clipping hole. The wrench has the functions that repeated combination and detaching are not needed during turning a part, and is smooth in use, high in efficiency and continuous in operation.
Description
Technical field
The present invention relates to a kind of open-end wrench, particularly relate to a kind of when pulling part, do not need repeatedly in conjunction with, break away from, but and have in the use quite smoothly, the open-end wrench of efficient height continued operation.
Background technology
Seeing also shown in Figure 1ly, is the structural representation of the existing open-end wrench of explanation structure of general open-end wrench and function.General common open-end wrench 100, comprise a lever 10 and two driving ends 11 that are connected to these lever 10 two ends, described driving end 11 comprises that respectively two separately geometrical clamp jaws 111, two are connected in the neck 112 of described geometrical clamp jaw 111 and this lever 10, and a folder cave 113 of being defined by described geometrical clamp jaw 111, this neck 112.Described geometrical clamp jaw 111 respectively has one towards this folder cave 113 and fixed clamp face 114 parallel to each other.
In use, the user can be socketed on the folder cave 113 of this driving end 11 outside the hexagonal nut 101, makes that described fixed clamp face 114 can be smooth with the opposite side of this nut 101, and then pulling this lever 10 just can be with these nut 101 turn.
Yet, generally when using this open-end wrench 100, in case the radius of turn of this lever 10 is subjected to the structure of periphery and stops and just can't continue to operate, must earlier this driving end 11 and this nut 101 be broken away from, after another feasible angle combination, just can continue to use again, so the user usually needs repeatedly both to be broken away from and combine, so cause many operational inconvenience and puzzlement, when especially using in operating space narrow or that be difficult for touching, originally this driving end 11 to be combined with this nut 101 and be difficult for, nowadays repeatedly both are broken away from again and combine, so will increase the operating difficulties degree significantly and reduce operational effect.
This shows that above-mentioned existing open-end wrench obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of open-end wrench of new structure, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Because the defective that above-mentioned existing open-end wrench exists, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of open-end wrench of new structure, can improve general existing open-end wrench, make it have more practicality.Through constantly research, design, and, create the present invention who has practical value finally through after studying sample and improvement repeatedly.
Summary of the invention
The objective of the invention is to, overcome the defective that existing open-end wrench exists, and provide a kind of open-end wrench of new structure, technical problem to be solved be make its provide a kind of do not need when pulling part repeatedly in conjunction with, break away from, but so that have in the use quite smoothly, the open-end wrench of efficient height continued operation, be very suitable for practicality.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of open-end wrench according to the present invention's proposition, comprise a lever and a driving end that is connected in this lever one end, this driving end comprises that a geometrical clamp jaw, one are interval in the live splint jaw of this geometrical clamp jaw, a neck that is connected in this geometrical clamp jaw and this live splint jaw, and folder cave of being defined by this geometrical clamp jaw, this live splint jaw, this neck, wherein: this geometrical clamp jaw, have a fixed clamp face that extends towards this neck towards this folder cave and from the opening part in this folder cave, and one extends to the concave face of this neck from this fixed clamp face; This live splint jaw, be to be articulated in this neck rotationally, and have a sour jujube piece, that protrudes from this inboard, folder cave and be formed on this sour jujube piece and inboard and be obverse stopping surface, with this fixed clamp face and extend and, reach a groove towards this neck towards the promotion face of this folder cave opening part from this stopping surface towards this folder cave; And this neck, have two pivot ears that extend these live splint jaw both sides respectively, and blind hole corresponding to this groove, this groove is between described pivot ear, this driving end also comprises a pivot and a flexible member, this pivot is stretched through described pivot ear and this live splint jaw, the stopping surface of permanent this sour jujube piece of interlock of this flexible member is towards this inboard, folder cave, this flexible member is one to be arranged at the compression spring in this blind hole, one end of this compression spring is to this groove, and the other end is in this blind hole.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Aforesaid open-end wrench, the live splint jaw of wherein said driving end also have one and extend to the block of this promotion face along this inboard, folder cave from the opening part in this folder cave, and this block is towards the fixed clamp face of this geometrical clamp jaw and is resisted against described pivot ear.
Aforesaid open-end wrench, the live splint jaw of wherein said driving end also have one and extend to the space of this stopping surface from this groove one side, and one is positioned at the rib that the opposite side of this groove is resisted against this neck.
The present invention compared with prior art has tangible advantage and beneficial effect.By technique scheme, open-end wrench of the present invention has following advantage and beneficial effect at least: open-end wrench of the present invention is when pulling a part, if pull direction is towards this geometrical clamp jaw by this live splint jaw, then can pushing against by this stopping surface and this fixed clamp face, this part of turn successfully is to reach the function that screws or unscrew, if and the radius of turn when pulling is hindered, then do not need to break away from this part, only need do in the opposite direction and pull, the promotion face that promotes this live splint jaw by the side of this part rotates and the formed space of this concave face is turned round, just can be so that this fixed clamp face and this stopping surface slip over the side of this part, so just can continue to come this part of turn along the previous direction of pulling, reaching does not need combination repeatedly, break away from this part, so that use quite smoothly, and has the high function of use of efficient.
