Description

Hand-twisting sleeve

Technical Field

The utility model relates to a fastener extracting tool, sleeve exactly says so.

Background

The sleeve is the extracting tool who is used for fasteners such as dismantlement bolt, nut, and traditional sleeve need connect supporting spanner just can use, has complex operation's defect. Moreover, the hole of the sleeve is an inner hexagonal hole, and the hole of the sleeve and the outer hexagonal head of the bolt must be completely matched to operate, so that the defect of low efficiency is caused.

Disclosure of Invention

The utility model discloses the invention purpose: for overcoming the defects existing in the prior art, the utility model provides a sleeve is twisted to hand with easy operation is convenient, efficient.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a sleeve is twisted to hand, includes the sleeve body, the sleeve body have with nut head complex moment of torsion delivery port, its characterized in that: the torque output hole comprises a cylindrical hole body, and six convex ribs which are uniformly distributed along the circumferential direction and extend along the axial direction are arranged on the upper bulge in the cylindrical hole body.

Through adopting above-mentioned technical scheme, the operation is held between the fingers to direct shaping flank board confession hand on the sleeve body to the operation of connecting handle has been saved, adopts the protruding muscle of design in the cylinder hole with bolt head complex moment of torsion delivery port in addition, compares than traditional interior hexagonal face, can realize that a plurality of angles embolias the bolt head with the sleeve, reaches the linkage of rotation direction through protruding muscle and hexagonal head cooperation, makes the sleeve embolia more simply, thereby improves operating efficiency.

Preferably, the starting end port of the torque output hole sleeved in the bolt head is provided with an inner chamfer. Under this structural design, avoid protruding and the corresponding equipment of fish tail of protruding muscle tip.

Preferably, the sleeve body is further provided with an outer hexagonal tool head in a matched mode, the outer hexagonal tool head comprises a cylindrical base portion sleeved in the torque output hole, a groove matched with the convex rib is formed in the cylindrical base portion, an outer hexagonal column protrudes out of the cylindrical base portion, a limiting end plate protruding out of the torque output hole in the radial direction is arranged at the rear end of the sleeve body, the convex rib is stopped on the limiting end plate, and the cylindrical base portion is inserted into the torque output hole and is limited through the limiting end plate. Under this structural design, outer hexagonal tool head can realize the bolt of the interior hexagonal head of hand twisting operation with the help of the socket head cap, realizes the function extension, provides the commonality of sleeve instrument.

Preferably, a permanent magnet ring is embedded on the limiting end plate, and the cylindrical base of the external hexagonal head tool is matched with the permanent magnet ring in a magnetic attraction manner. Under the structural design, the permanent magnetic ring on the limiting end plate can ensure that the external hexagon head tool is reliably inserted on the sleeve body, is not easy to fall off and is convenient to operate; in addition, the design of permanent magnetism ring is convenient to inhale the bolt magnetism, avoids the bolt to drop.

Preferably, the convex rib is in a convex arc shape, and the width of the base part of the convex rib is greater than the convex height of the convex rib. Under this structural design for the part embolias more smoothly, can guarantee the intensity of protruding muscle.

The present invention will be further described with reference to the accompanying drawings.

Detailed Description

Referring to the drawings 1-4, the utility model discloses a sleeve is twisted to hand, including sleeve body 1, sleeve body 1 have with nut head complex moment of torsion delivery outlet 11, sleeve body 1 outer periphery on the arch have two confession hands to hold between the fingers flank board 2 of operation, moment of torsion delivery outlet 11 includes cylinder hole body 111, the arch has six protruding muscle 112 along circumference evenly distributed, along axial extension in cylinder hole body 111. The ribs 112 are preferably convexly curved, and the width of the base of the ribs 112 is greater than the height of the ribs 112. So that the parts can be smoothly sleeved and the strength of the convex rib 112 can be ensured. The beginning end of the torque output hole 11 sleeved in the bolt head is provided with an inner chamfer. The end of the rib 112 is prevented from protruding to scratch the corresponding equipment.

The rear end of the sleeve body 1 is provided with a limiting end plate 12 which radially protrudes out of the torque output hole 11, the convex rib 112 is stopped on the limiting end plate 12, and the limiting end plate 12 is embedded with a permanent magnet ring 3 for adsorbing a fixing bolt and avoiding falling; the limiting end plate 12 is annular.

In addition, the sleeve body 1 is also matched with an outer hexagonal tool bit 4, the outer hexagonal tool bit 4 comprises a cylindrical base portion 41 sleeved in the torque output hole 11, a groove 411 matched with the convex rib 112 is arranged on the cylindrical base portion 41, an outer hexagonal column 42 protrudes from the cylindrical base portion 41, and the cylindrical base portion 41 is inserted into the torque output hole 11 and limited by a limiting end plate 12. The outer hexagonal tool head 4 can be used for realizing the bolt for screwing the inner hexagonal head by hand by means of an inner hexagonal sleeve, realizing function expansion and providing the universality of sleeve tools. The cylindrical base 41 of the external hexagon head tool is matched with the permanent magnet ring 3 in a magnetic attraction way. The permanent magnet ring 3 on the limiting end plate 12 can enable an outer hexagon head tool to be reliably inserted into the sleeve body 1, and the outer hexagon head tool is not easy to drop and convenient to operate. The utility model discloses a sleeve, the operation is held between the fingers to shaping flank board 2 confession hand on sleeve body 1 directly to the operation of connecting handle has been saved, adopts the protruding muscle 112 of the downthehole design of cylinder with bolt head complex moment of torsion delivery outlet 11 in addition, compares than traditional interior hexagonal face, can realize that a plurality of angles embolia the bolt head with the sleeve, reaches the linkage of rotation direction through protruding muscle 112 and the cooperation of hexagonal head, makes the sleeve embolia more simply, thereby improves operating efficiency.
