Abstract

The utility model relates to a heterotypic spanner, which is mainly composed of a head with club hole, and a spanner structured with a handle. The utility model is characterized in that the two end surfaces with club hole and the handle axis line shows a vertical bending form; at the other end of the handle, an inner hexagonal rod sharing the axle with the handle is positioned. The utility model has the advantages that the club spanner showing the form as the Chinese character one can not chuck the screwing part in a narrow place or there is no steering angle when being fastened or dismounted; in the mean time, the inner hexagonal rod can be used to transmit the maximum swing motion of the spanner into circle rotation of the inner hexagonal rod. The utility model can be applied to fasten or dismount the screwing part in a narrow place or a special place, through the inner hexagonal rod being connected with a plurality of ordinary tools, which can not only save the time, improve the working efficiency, lighten the working intensity of the operator but also provide a better utilization value.

Description

Special-shaped spanner
Technical field
The utility model belongs to the hardware ﹠ tools technical field, particularly relates to a kind ofly being suitable for fastening or removing and installing the screw narrow again in specific position and space or the special-shaped spanner of nut.
Background technology
Spanner is a kind of common tool of degree of tightness nut, bolt, mainly containing types such as combination wrench, open-end wrench, ring spanner and ratchet-type speeder wrench in the known technology at present, its structure of widely used double offset ring spanner comprises the wrench body that is made of a head and one handle substantially, and handle and head are that integral body is " one " font structure.After when operation, mainly being to utilize the set plum-blossom sleeve oral area of Wrench head to be set in the hexagonal screw piece of tool, applying a spanner power again, and make screw piece reach the effect of fixing and dismounting.When general double offset ring spanner is desired to reach the fixing and dismounting of screw piece; often double offset ring spanner need be done and repeatedly back and forth pull and to achieve the goal; this is because when fixing and dismounting screw piece; this screw piece periphery regular meeting has bar or screw piece peripheral space narrow; so when double offset ring spanner screw piece is pulled to the contacted angle of bar after; need double offset ring spanner by taking out on the screw piece; again double offset ring spanner is overlapped oral area and aim at the hexagonal socket part of screw piece; can pull screw piece once more; pulling through repeated multiple times like this; take out; the alignment sleeve card can reach the effect of the fixing and dismounting of screw piece after numerous and diverse operation of repeatedly pulling.Though aforesaid double offset ring spanner can provide user one to have function fixing and the loading and unloading screw piece, really has progressive, but in practical operation, but find also to have in its structure some shortcomings, cause that operating efficiency is quite low in actual applications, increase labor intensity of operating personnel simultaneously, failed to reach best result of use.
Because the deficiency that above-mentioned existing double offset ring spanner exists, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, in the hope of having developed a kind of special-shaped spanner of new structure, make it have more practicality, and, create the utility model that has practical value finally through after continuous research, design and really making sample repeatedly.
Summary of the invention
The utility model provides a kind of simple in structure, time saving and energy saving, with low cost and be suitable for fastening or remove and install the special-shaped spanner of the screw piece narrow again in specific position and space for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Special-shaped spanner, comprise that mainly one has the head in plum blossom aperture and the wrench body that one handle constitutes, it is characterized in that: the head both ends of the surface and the handle axis that have the plum blossom aperture are the vertical curve shape, be provided with the interior hexagonal body of rod that is connected as a single entity with it at the described handle other end, the hexagonal body of rod and handle concentric in this.
The utility model can also adopt following technical measures:
Described head and the handle vertical bend that has the plum blossom aperture is designed to ladder bowing structure.
The described handle other end also can be by the hexagonal body of rod in being welded with.
Advantage and the good effect that the utlity model has are: because head design and handle that the utility model will have a plum blossom aperture are the vertical curve shape, have overcome integral body like this and be " one " font double offset ring spanner fastening or when dismantling the screw piece that is in narrow space and the shortcoming that double offset ring spanner can't block and not have steering angle with its cover; The utility model hexagonal body of rod in the other end of pinch bar is connected with can utilize spanner to rotate the interior hexagonal body of rod during dismounting screw piece in addition, the oscillating motion of spanner large space is converted to the circumference rotation of the interior hexagonal body of rod; This abnormal shape spanner structure simplicity of design essence is little, be specially adapted to fastening or remove and install at specific position and the narrow screw piece of surrounding space, also can connect multiple general tool by the interior hexagonal body of rod on the handle dismantles with fastening, it not only saves time, improves work efficiency, and alleviates labor intensity of operating staff.Thereby make it more practical, quite have the value of industry.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Among the figure: the head that 1, has the plum blossom aperture; 2, ladder bowing portion; 3, handle; 4, the interior hexagonal body of rod.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of special-shaped spanner, comprise that mainly one has the head 1 in plum blossom aperture and the wrench body that one handle 3 constitutes, head 1 both ends of the surface and the handle axis that have the plum blossom aperture are the vertical curve shape, and described head and the handle vertical bend that has the plum blossom aperture is designed to be ladder bowing portion 2.Here curved handle portion being designed to ladder bowing portion is to consider the stressed reason of handle and the intensity of the oral portion of plum blossom hole.Be provided with the interior hexagonal body of rod 4 that is connected as a single entity with it at the described handle other end, the hexagon body of rod 4 in the present embodiment handle 3 other ends being machined directly to.The hexagonal body of rod and handle concentric in described.Also can be at the described handle other end by the hexagonal body of rod 4 in being welded with.
Operation principle of the present utility model is described below: during use, the head cover that has the plum blossom aperture of special-shaped spanner is stuck on the nut of needs dismounting, make the handle and the interior hexagonal body of rod remain on horizontal direction, and then use the double offset ring spanner or the internal hexagonal body of rod of monkey wrench that are complementary with the interior hexagonal body of rod to rotate clockwise or counterclockwise, promptly finish the fastening of nut or dismounting.
