Description

Quick hexagonal spanner

Technical Field

The utility model belongs to the spanner field, more specifically the utility model relates to a quick hexagonal spanner that says so.

Background

The wrench is a common mounting and dismounting tool, and is a manual tool for screwing bolts, screws, nuts and other screw threads to tightly hold open or trepanning fasteners of the bolts or nuts by utilizing the lever principle. The wrench is usually made of carbon or structural steel made of alloy material, and usually has an opening or a sleeve hole for holding a bolt or a nut formed at one end or both ends of a handle portion, so that the bolt or the nut can be screwed by applying an external force to the handle portion along a thread rotation direction in use.

When operating in the little space, it has open-ended spanner to adopt the tip usually, the spanner includes stalk portion and clamping part this moment, if when screwing to hexagon nut or bolt, the inside four limits that can set up of clamping part, laminate then to twist with four limits of hexagon nut or bolt respectively, nevertheless when the secondary is screwed, need break away from behind hexagon nut or the bolt with the clamping part completely and select a position with clamping part again with hexagon nut or bolt fastening, it is comparatively troublesome that the spanner blocks hexagon nut or bolt repeatedly at every turn, and to present spanner, its clamping part is the incomplete symmetrical structure, the thickness of its each position is different, lead to in narrow and small space, the part of clamping part can stretch into other part can not stretch into the operation again, it is whole limited great.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a when screwing away hexagon nut or bolt in narrow and small space, can reset fast after rotating certain angle and carry out the secondary operation, the quick hexagon spanner of raising efficiency.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a quick hexagonal spanner, includes stalk portion and clamping part, the clamping part is including two card arms that are the V-arrangement, the tip of two card arms is connected with the arm of exerting oneself and support arm respectively, the arm of exerting oneself is parallel with the support arm opposite face, the length of support arm is less than the length of the arm of exerting oneself, two card arms, the arm of exerting oneself and support arm form the bayonet socket.

Furthermore, the outer part of the clamping part is arc-shaped, and the circle where the clamping part is located is concentric with the inscribed circle where the bayonet of the clamping part is located.

Further the support arm has a length 1/4 to 1/5 of the length of the force application arm.

Compared with the prior art, the beneficial effects of the utility model are that: clamping part is through two card arms, execute the arm of force and support arm and can block hexagon nut or bolt and twist the commentaries on classics, it changes to twist many times to need repeatedly in the narrow and small space, every twists and has changeed once the back, only need leave its face in place with the tip of support arm, can reset whole spanner, then block the cooperation once more with hexagon bolt or nut fast, twist and change hexagon nut or bolt, reach the purpose of twisting the commentaries on classics nut fast in narrow and small space, and the outside of clamping part can be coaxial with hexagon nut or bolt, as long as the stalk portion does not have the hindrance can twist the commentaries on classics, increase the single and twist the angle scope.

Detailed Description

Embodiments of the present invention will be further described with reference to fig. 1 to 3.

The utility model provides a quick hexagonal spanner, includes stalk portion 1 and clamping part 2, clamping part 2 is including two card arms 21 that are the V-arrangement, the tip of two card arms 21 is connected with the arm of exerting oneself 23 and support arm 22 respectively, the arm of exerting oneself 23 is parallel with support arm 22 opposite face, support arm 22's length is less than the length of the arm of exerting oneself 23, two card arms 21, the arm of exerting oneself 23 and support arm 22 form the bayonet socket.

Wherein, the two clamp arms 21 are 120 degrees, the force applying arm 23 and the supporting arm 22 are respectively 120 degrees with the clamp arm 21 connected with the force applying arm and the supporting arm.

As shown in fig. 2, in this embodiment, taking the turning of the hexagon bolt 3 as an example, at this time, the middle hexagon bolt 3 needs to be turned, and shielding obstacles are provided on both the left and right sides, that is, the rotatable range of the entire wrench is limited, at this time, the hexagon bolt 3 needs to be turned counterclockwise, the clamping portion 2 is clamped on the hexagon bolt 3, the supporting arm 22 is located on the left side of the force applying arm 23, the force is applied to the handle portion 1 along the direction a after the force is applied, and the bolt is turned; after once twisting the completion, the stalk portion 1 of spanner will arrive the left side position and can't continue to rotate, as shown in fig. 3, mention the spanner, make support arm 22 leave the hexagonal bolt 3 face of its laminating can, clamping part 2 and hexagonal bolt 3 are unrestricted each other this moment, make the spanner rotate clockwise, b direction in fig. 3 promptly, make the spanner reset, then push into the spanner, make support arm 22 laminate once more with the face of hexagonal bolt 3 and can twist the commentaries on classics, when needs twist the commentaries on classics many times, all only need remove the microspur when the spanner resets every time and can break away from hexagonal bolt 3 and reset, and when blocking with hexagonal bolt 3 once more, it is easier, reach quick repetition and twist and change the bolt.

The preferred outside of clamping part 2 of this embodiment is circular-arc, and its circle of place is concentric with the inscribed circle at the bayonet socket place of clamping part 2, and in the process of twisting promptly, can not lead to unable the twist hex bolts 3 because of the appearance of clamping part 2, makes the spanner twist the angle and reach the biggest.

The length of the supporting arm 22 is preferably 1/4 to 1/5 of the length of the force applying arm 23, so that the supporting arm 22 can be ensured to be attached to the surface of the hexagon bolt 3, a complete supporting effect is achieved, and the hexagon bolt 3 can be quickly separated.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
