Abstract

The invention discloses a U-shaped bolt nut spanner. The U-shaped bolt nut spanner comprises a spanner body and a handle. A first clamping device and a second clamping device are arranged in the spanner body. A nut cavity is formed in the middle of the first clamping device. A first gear is arranged on the outer edge of the first clamping device. A cavity is formed in the middle of the second clamping device. A second gear is arranged on the outer edge of the second clamping device. The first gear and the second gear are meshed with each other. The spanner is provided with the two parallel clamping devices. The first clamping device is used for clamping a nut. The second clamping device is used for providing a power source. The first clamping device is inserted in the cavity in the middle of the second clamping device through a motor or other mechanisms. The first clamping device is driven to rotate through the meshed gears of the two clamping devices, and therefore the purpose of detaching the U-shaped bolt nut is achieved. According to the U-shaped bolt nut spanner, firstly, the second clamping device can be used for providing the extra power source, the second clamping device is at the other end of the nut and not constrained by space, and use is convenient.

Description

U-shaped card nut spanner

Technical field

The present invention relates to a kind of U-shaped card nut spanner.

Background technology

U-shaped card is again u shape bolt, i.e. U-bolts, U-bolts English name is U-bolt, criteria of right and wrong part, shape is that U-shaped is so also referred to as U-bolt, two has screw thread can be combined with nut, is mainly used in fixing tube if water pipe or tablet are as the leaf spring of automobile, has many uses too general at construction and installation, mechanical fitting connection, shipping vehicle, bridge tunnel railway etc.Principal shape: semicircle, square right angle, triangle, oblique triangle etc.Current U-shaped card nut is due to own form and installing space reason, and bad dismounting, is not also applicable to this type of instrument at present.

Summary of the invention

For above-mentioned prior art Problems existing, the invention provides a kind of U-shaped card nut spanner, dismantle U-shaped card nut fast and easy, space constraint is little.

To achieve these goals, the technical solution used in the present invention is: a kind of U-shaped card nut spanner, comprise, wrench body and handle, handle is fixedly connected with wrench body, described wrench body is built-in with first and blocks device and second and block device, and described first blocks in the middle of device and have nut cavity, and first blocks device outer rim has the first gear;

Second blocks device centre has cavity, and second blocks device outer rim has the second gear,

The first described gear and the second gear engage each other.

Further optimization, the described first nut cavity blocked in the middle of device is hexagon cavity.

Further optimization, the described second cavity blocked in the middle of device is hexagon cavity.

Further optimization, the described second cavity blocked in the middle of device is triangular cavity or square cavity.

Further optimization, described handle and wrench body are for removably connecting.

Further optimization, described handle is L-type.

The application have two be arranged in parallel block device, wherein first block device for blocking nut, second blocks device for providing power source, insert second by motor or other mechanisms and block the middle cavity of device, and block device pitch wheel by two, drive first to block device to rotate, and then reach the object dismantling U-shaped card nut.The application first second can be utilized to block power source that device provides extra, and second blocks device other one end at nut, is not subject to the constraint in space, uses more for convenience.Handle is L-type, makes the height of handle and wrench body not at grade, handle is more easily held, and not by the constraint in space.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present invention.

Fig. 2 is Fig. 1 is side view.

In figure: 1, wrench body, 2, first blocks device, the 3, first gear, and 4, second blocks device, the 5, second gear, and 6, handle.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described.

As depicted in figs. 1 and 2, a kind of U-shaped card nut spanner, comprises, wrench body 1 and handle 6, handle 6 is fixedly connected with wrench body 1, and described wrench body 1 is built-in with first and blocks device 2 and second and block device 4, first block device 2 and second block device 4 can own rotation

Described first blocks device 2 centre has nut cavity, and first blocks device 2 outer rim has the first gear 3;

Second blocks device centre has cavity, and second blocks device 4 outer rim has the second gear,

The first described gear and the second gear engage each other, and first blocks device 2 and second is blocked device 4 and can mutually be rotated by gear, block mainly through second the rotation that device 4 drives first to block device 2,

Further optimization, the described first nut cavity blocked in the middle of device 2 is hexagon cavity.

Further optimization, described second cavity blocked in the middle of device 4 is hexagon cavity, and of coursing the second cavity blocked in the middle of device 4 is triangular cavity or square cavity, inserts cavity by the specific purpose tool of correspondence, for it provides power source, can be also can be manually driven by motor.

Further optimization, described handle is L-type.

During use, the nut cavity blocking device 2 by first is inserted on the U-shaped card nut that will dismantle, utilize electric tool or hand-operated tools to insert second and block the middle cavity of device 4, drive second to block device 4 to rotate, second blocks device 4 drives first to block device 2 and rotate by pitch wheel, and then reaches the object of dismounting nut.
