The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1, fig. 2, fig. 3 is embodiment 1 schematic structure diagram, the utility model relates to an instrument of uncapping, including nut end 1, base 2 and a plurality of pawl 3, wherein, a plurality of pawl 3 distributes along the circumference of base 2, base 2 is corresponding with the middle part of instrument end cover, during the use, base 2 sits the middle part of dress at the instrument end cover, and simultaneously, every pawl 3 all corresponds the joint with the recess at instrument end cover edge, adopts spanner or other instrument joint nut end 1, drive nut end 1 in proper order through external force, base 2, pawl 3, the instrument end cover, come to open or screw up the instrument end cover.

As shown in fig. 4, which is a schematic structural diagram of embodiment 2, in this embodiment, the nut end 1 is an outer hexagon nut, but in practical application, a square head or other various structural styles may also be adopted. In another deformation mode, the upper surface of the nut end head 1 is concavely provided with an inner hexagonal counter bore 4, so that tools such as an adapter and a screwdriver can be conveniently matched for use.

In this embodiment, a plurality of pawls 3 are uniformly distributed along the circumferential direction of the base 2, and generally, 6 pawls 3 are provided, so that the number of the pawls 3 can be increased or decreased according to an actual use scene. The pawl 3 is arranged in an integral structure or a split structure.

In the actual use process, the instrument end cover has various structural styles such as different sizes, different numbers of grooves on the edge of the instrument end cover, irregular shapes and the like, and for the structural styles, as shown in fig. 5, 6, 7, 8 and 9, the structural schematic diagram of embodiment 3 is shown, and in this embodiment, the instrument cover opening tool with the following deformation styles is adopted: the pawl 3 comprises a pawl arm 5, a sliding rod 6 and a pawl sliding head 7, the pawl sliding head 7 is fixedly arranged at the end part of the sliding rod 6, the pawl arm 5 is a fixed part, and the sliding rod 6 and the pawl sliding head 7 are connected together to form a movable part. And a slide rail 8 is arranged in the pawl arm 5, the slide rod 6 can be inserted into the slide rail 8, and the slide rod 6 can slide along the radial direction of the base 2 under the guiding and positioning action of the slide rail 8, so that the extending length of the pawl head 7 can be adjusted, and the use requirements of instrument end covers with different diameters can be met.

Namely: when opening or tightening a large instrument end cap, the slide bar 6 can be extended so that the slide pawl head 7 expands to a larger diameter. When the small-sized instrument cover is opened or tightened, the slide bar 6 can be recovered so that the slide pawl head 7 is reduced to a small diameter.

In order to position the slide bar 6 conveniently, an elastic steel ball 9 for clamping is arranged between the slide rail 8 and the side wall of the slide bar 6, and after the slide bar 6 and the slide rail 8 are positioned, the safety in work can be effectively improved.
