Abstract
The utility model relates to a tool and in particular relates to a wrench. The wrench structurally comprises a wrench head part (1) and a wrench handle (3), wherein one end of the wrench handle (3) is fixedly connected with the wrench head part (1) through an angle twisting connecting part (2); the wrench further comprises a connecting rod (4); a counter bore (5) is arranged at one end of the wrench handle (3), which is far away from the wrench head part (1); and the connecting rod (4) is inserted into the counter bore (5) and is connected to the tail part of the wrench handle (3). The angle twisting connecting part (2) can be used for lifting the plane of the wrench handle (3), which corresponds to the wrench head part (1), so as to be convenient to grasp by hands; meanwhile, the wrench handle (3) is prevented from being blocked by obstacles in a rotating process and can be directly twisted; and the connecting rod (4) is arranged at the tail part of the wrench handle (3) and a torque can be enlarged under the effect of an equal force.
Description
Technical field
The utility model relates to a kind of instrument, relates in particular to a kind of spanner.
Background technology
In the practical operations such as assembly and disassembly of mechanical field, spanner is one of indispensable instrument of pincers worker and assembling.
Required labour is bigger for spanner, when taking very inconvenience holding of bigger plane upper ejector lever, then needs Panasonic more again on the folder if meet barrier, has increased a lot of workloads, makes inefficiency, wastes time and energy.
At present; A kind of hub spanner is arranged on the market; Can Wrench head and pinch bar be arranged at two Different Plane that certain distance is arranged respectively, making things convenient for the grasping of hand, but hand takes the position of holding indefinite; To such an extent as to the active force that same moment of torsion needs is also different, use the required labour of spanner still very big.
Therefore, how to provide a kind of can solve existing spanner hold take inconvenient, laborsaving, spanner is the technical problem that those skilled in the art need to be resolved hurrily easily.
The utility model content
The purpose of the utility model is to provide a kind of spanner, holds by inconvenient to solve existing spanner, and the problem that wastes time and energy.
For solving the problems of the technologies described above; The utility model provides a kind of spanner; Comprise: Wrench head and pinch bar, said Wrench head is fixedly connected with said pinch bar, and said spanner also comprises a connecting rod; Said pinch bar is provided with a counterbore away from an end of said Wrench head, and an end of said connecting rod inserts in the said counterbore and links to each other with pinch bar.
Optional, said spanner also comprises angle distortion connecting portion, and said pinch bar is fixedly connected through said angle distortion connecting portion with said Wrench head, and plane, said Wrench head place is different with plane, said pinch bar place.
Optional, the distance between said Wrench head plane, place and the plane, said pinch bar place is 2-4 a times of said Wrench head thickness.
Optional, the distance between said Wrench head plane, place and the plane, said pinch bar place is 3 times of said Wrench head thickness.
Optional, said angle distortion connecting portion is a curved slab.
Optional, said angle distortion connecting portion is to face plate directly.
The spanner that the utility model provides comprises a connecting rod; Said pinch bar is provided with a counterbore away from an end of said Wrench head, and an end of said connecting rod inserts in the said counterbore and links to each other with pinch bar, holds said connecting rod during work; The friction on the plane that hand and said Wrench head belong to when both having avoided holding said pinch bar rotation; Cause hand injured, can make arm of force lengthening as far as possible again, to reach the labour-saving effect.
The spanner that the utility model provides also comprises angle distortion connecting portion, and said pinch bar is fixedly connected through said angle distortion connecting portion with said Wrench head, and plane, said Wrench head place is different with plane, said pinch bar place.Distance between said Wrench head plane, place and the plane, said pinch bar place is 2-4 a times of said Wrench head thickness; Preferably 3 times; Insert between said pinch bar plane, place and the plane, said Wrench head place to reach staff, and hold the needed distance of said pinch bar.Said angle distortion connecting portion can select to face directly plate or curved slab, can reach above-mentioned functional requirement and get final product.
Description of drawings
Fig. 1 is the structural representation of the spanner of the utility model one embodiment;
Fig. 2 is the upward view of the spanner of Fig. 1.
The specific embodiment
For above-mentioned purpose, the feature and advantage that make the utility model can be more obviously understandable, the specific embodiment of the utility model is done detailed explanation below in conjunction with accompanying drawing.
This spanner; Its structure is as depicted in figs. 1 and 2, comprising: Wrench head 1 and pinch bar 3, and said pinch bar 3 is fixedly connected with Wrench head 1; Said spanner also comprises a railing 4; Said pinch bar 3 is provided with a counterbore 5 away from an end of said Wrench head 1, and said counterbore 5 is arranged on the said pinch bar 3 as much as possible away from the position of Wrench head 1, and an end of said connecting rod 4 inserts in the said counterbore 5 and links to each other with said pinch bar 3.The end that said pinch bar 3 is connected with said Wrench head 1 is provided with angle distortion connecting portion 2, and particularly, said angle distortion connecting portion 2 can be selected curved slab for use or face plate directly.
The end that said pinch bar 3 is connected with said Wrench head 1 is provided with angle distortion connecting portion 2; Can pinch bar 3 be raised with respect to the plane at Wrench head 1 place; Make the grasping and the application of force of the enough staff's hands in space between Wrench head plane, 1 place and the pinch bar 3; Particularly, the 2-4 that said angle distortion connecting portion 2 is raised to Wrench head 1 thickness with respect to plane, Wrench head 1 place with plane, pinch bar 3 place doubly, optimum is 3 times; Insert between said pinch bar plane, 3 place and the plane, said Wrench head 1 place to reach staff, and hold said pinch bar 3 needed distances.Said angle distortion connecting portion 2 can select to face directly plate or curved slab, can reach above-mentioned functional requirement and get final product.As far as possible be provided with a counterbore 5 away from the position of Wrench head 1 at pinch bar 3 other ends, said counterbore 5 internal diameters are equal to or slightly greater than said connecting rod 4 external diameters, and an end of connecting rod 4 is inserted in the said counterbore 5; The staff holds connecting rod 4, and the friction on the plane that hand and said Wrench head 1 belong to when both having avoided holding said pinch bar 3 rotations causes hand injured; Because counterbore 5 positions are away from Wrench head 1; Increased brachium, according to moment of torsion=active force * brachium, under the effect of equivalent effect power; The moment of torsion square that produces is big, reaches effect of saving time and labor.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
