Description

Simple wrench for screwing screw

Technical Field

The utility model relates to a hardware and tools field, in particular to a simple and easy spanner for twisting screw.

Background

The screw is a tool for fastening the parts of the object step by utilizing the physics and mathematical principles of the inclined circular rotation and friction of the object. Screws are a common term for fasteners, a common spoken word. The outer hexagon head is arranged at one end of most screws, so that the outer hexagon head becomes an outer hexagon screw, the nuts of the screws are universal in production and life, the adjustable spanner or the nonadjustable spanner matched with the adjustable spanner is used for screwing and unscrewing the outer hexagon head screws or the nuts, the spanner is usually rotated in a plane vertical to the screws, the hand holding posture needs to be changed or the hand holding posture needs to be changed when the spanner is rotated for one circle, and the operation is very inconvenient when the spanner is rotated for screwing or unscrewing the screws.

For the outer hexagonal screw or nut, the screwing and unscrewing operations are performed using wrenches, which are usually rotated perpendicular to the plane of the screw, and when the operation is performed, the hand needs to be changed or the hand-held posture needs to be changed for one rotation, and when the operation is performed for many rotations to screw or unscrew the screw, the operation is very inconvenient.

Disclosure of Invention

The utility model aims to provide a: the simple wrench for screwing the screw is provided, and the problem that the operation of screwing and unscrewing the outer hexagon screw or the nut is carried out by using the wrench, the wrench usually rotates in a plane perpendicular to the screw, the hand holding posture needs to be changed or the hand holding posture needs to be changed when the wrench rotates for one circle, and the operation is very inconvenient when the wrench rotates for many circles to screw or unscrew the screw is solved.

The utility model adopts the technical scheme as follows:

the utility model provides a simple and easy spanner for twisting screw, includes the chuck of clamping screw, bracing piece and the rotary rod be connected with the chuck, chuck adaptation screw for clamping screw, bracing piece one end is connected in one side of chuck horizontal plane, the rotatable other end that is connected to the bracing piece of rotary rod, the plane at rotary rod perpendicular to chuck and bracing piece place.

Here chuck and bracing piece have constituted the spanner among the prior art, and we have fixed a rotary rod in the one end of bracing piece, the plane at chuck and bracing piece place is perpendicular to the rotary rod, when screwing up or the screw with the spanner, with the outer hexagon screw of chuck straining or nut, hold the rotary rod, direct rotation, because the rotary rod is rotatable being connected to the bracing piece, therefore when holding the rotary rod and around the tight screw rotation of chuck clamp, the hand does not need to alternate the posture, can direct rotation, screw up or unscrew the screw, to long screw or need rotate more circles in order to screw up or unscrew the application scene of taking out the screw, and convenient operation is very practical.

Further, the rotary rod passes through bearing A and the bracing piece is connected, bearing A is embedded in the bracing piece, bearing A's outer loop and bracing piece are connected, and bearing A's interior loop is cup jointed on the rotary rod.

To the specific rotatable connected mode of rotary rod and bracing piece, we are connected to the bracing piece with the rotary rod through bearing A's mode on, when rotatory like this, hold rotary rod rotary supporting rod, make when the bracing piece is rotatory through bearing A, the rotary rod can keep its self irrotational, consequently hold the posture of rotary rod and also can keep unchangeable, in the application scene that need rotatory many circles in order to screw up or unscrew and take out the screw, convenient operation, it is very practical.

Further, the rotary rod is arranged to be an inner fixing rod and an outer rotary rod, the inner fixing rod is fixed at one end of the supporting rod, and the outer rotary rod is sleeved on the inner fixing rod.

Furthermore, the inner fixing rod and the outer rotating rod are connected through a plurality of bearings B, the outer ring of each bearing B is connected with the outer rotating rod, and the inner ring of each bearing B is sleeved on the inner fixing rod.

To the specific another kind rotatable connected mode of rotary rod and bracing piece, we set up the rotary rod into outer swinging arms and the interior dead lever that cup joints, interior dead lever is fixed on the bracing piece, and outer swinging arms cup joints on the interior dead lever through bearing B, this kind of structure, when rotatory, hold outer swinging arms when driving the bracing piece rotatory, interior dead lever and bracing piece are rotatory together, because interior dead lever and outer swinging arms pass through a plurality of bearing B and connect, outer swinging arms can keep its self irrotational, consequently hold the posture of outer swinging arms also can keep unchangeable like this, in the application scene of taking out the screw in order to tighten or loosen more circles that need rotate, high durability and convenient operation, and is very practical.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model relates to a simple and easy spanner for twisting screw has solved to outer hex bolts or nut, uses the spanner to screw up and unscrew the operation, and these spanners are usually rotatory at the plane of perpendicular to screw, and during the operation, rotatory round needs the gesture of changing hands or need transform to hold, when needs rotatory a lot of rings are used for screwing up or unscrew the screw, operates very inconvenient problem.

2. The utility model relates to a simple and easy spanner for twisting screw, convenient operation, and simple structure, low in production cost.
