Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-5, a screw convenient to dismantle, includes screw rod 1, and the tip of screw rod 1 is equipped with screw cap 2, and screw cap 2 keeps away from 1 side surface of screw rod and sets up triangular holding tank 3, and place piece 4 in holding tank 3's inside, and place piece 4's opposite side surface and set up the slot, and the corresponding piece 4 of placing of each side inner wall of holding tank 3 all installs matched with centre gripping subassembly.

As a technical optimization scheme of the utility model, the clamping assembly comprises a pressure spring 5 and a support pillar 6, a matching mounting groove is arranged in the screw cap 2 corresponding to the support pillar 6, the support pillar 6 is slidably arranged in the mounting groove, and the pressure spring 5 is arranged between the end of the support pillar 6 and the bottom surface of the mounting groove; the clamping assembly is arranged so that the placing block 4 does not automatically disengage from the nut 2 when not forced by a person.

As a technical optimization scheme of the utility model, each side surface of the placing block 4 is provided with a circular arc-shaped groove corresponding to the top pillar 6, and one end of the top pillar 6 extending into the groove is in a circular arc shape; the setting of recess for the fore-set 6 is when carrying out the centre gripping to placing piece 4, can not influence the dismantlement of placing piece 4.

As a technical optimization scheme of the utility model, each corner of the placing block 4 extends to the outside of the containing groove 3 and is provided with a limiting bulge 7, and a space is arranged between each limiting bulge 7 and the end part of the screw rod 1; the arrangement of the limiting bulge 7 enables a person to rotate the screw cap 2 more conveniently.

As a technical optimization scheme of the utility model, a placing groove is arranged on the bottom surface of the holding groove 3, a magnet block 8 is arranged in the placing groove, and the magnet block 8 is attached to the placing block 4; the magnet block 8 is arranged, and the fixing effect on the placing block 4 is further improved.

As a technical optimization scheme of the utility model, the outer ring surface of the screw rod 1 is sequentially sleeved with the non-slip mat 10 and the cotton mat 11, the inner part of the cotton mat 11 is soaked by the maintenance oil, and the diameter of the cotton mat 11 is larger than the diameters of the screw cap 2 and the non-slip mat 10; due to the arrangement of the cotton pad 11, the screw has a good antirust effect.

As a technical optimization scheme of the utility model, a plurality of clamping strips 9 are fixed on each side surface of the holding tank 3, a matched clamping groove is formed on each side surface of the placing block 4 corresponding to the clamping strip 9, and each clamping strip 9 is clamped inside the adjacent clamping groove; the setting of card strip 9 for it is more stable when placing piece 4 and holding tank 3 contact.

The use principle and the advantages are as follows: when the utility model is used, when an external object needs to be fixed through a screw, a person clamps the placing block 4 in the accommodating groove 3, and then the person connects the end part of an external screwdriver with the slot on the surface of the placing block 4, and at the moment, the person can rotate the placing block 4 through the screwdriver, so that the placing block 4 drives the screw rod 1 to rotate through the screw cap 2, namely, the external object is fixed; and because be equipped with between slipmat 10 and the screw cap 2 by the cotton pad 11 that the maintenance oil soaked to after the screw is connected with external object, keep apart by cotton pad 11 between its object and the screw cap 2, reduced the screw for a long time when exposing in the external world promptly and the phenomenon of corrosion between the object.

Further in this scheme use, when personnel need to dismantle the screw, personnel pass through screwdriver reverse rotation, thereby make the screw break away from external object, and then after the screw exposes in the external world for a long time, corrosion in its slot of placing piece 4 or slot are because of dismantling many times and grind when being even, personnel can take out placing piece 4 at this moment from holding groove 3, put into new placing piece 4 in holding groove 3 inside, thereby make personnel can apply force to placing piece 4 after changing through the screwdriver, so that the screw can be conveniently dismantled from the object; when the person does not carry the cross screwdriver or the straight screwdriver, the person can take down the placing block 4, and the accommodating groove 3 is triangular, so that the person can apply force to the screw cap 2 through the special-shaped triangular screwdriver; therefore, the problem that when the screw is used for a long time in the traditional scheme, after the end part of the screwdriver is ground in the slot of the end face of the screw, the screwdriver slips when applying force to the screw, the screw is detached under the influence, and the screwdriver cannot be applied to various screwdrivers is solved.

Further in this scheme use, when various screwdrivers of personnel are and carry, personnel can use sharp-nosed pliers centre gripping at the outer anchor ring of screw cap 2, and twist it and move, thereby make personnel's accessible sharp-nosed pliers dismantle the screw, and be equipped with spacing arch 7 owing to each angle of placing piece 4, and each spacing arch 7 all extends to the outside of screw cap 2, and then when personnel rotated screw cap 2 through sharp-nosed pliers, its spacing arch 7 can carry on spacingly to sharp-nosed pliers, thereby make sharp-nosed pliers can be more convenient carry out the application of force to screw cap 2.

Meanwhile, the corresponding placing block 4 in the screw cap 2 is provided with a clamping assembly matched with the clamping assembly, namely, the ejection column 6 moves towards one end far away from the pressure spring 5 under the action of the pressure spring 5, so that the end part of the ejection column 6 extends into a groove of each wall of the placing block 4, namely, the ejection column 6 clamps the placing block 4, the placing block 4 is prevented from being separated from the inside of the accommodating groove 3 when force is not applied by personnel, and the stability of the placing block 4 in use is improved; and because the interior bottom surface of holding tank 3 is equipped with the standing groove and has magnet piece 8 at the internally mounted of standing groove to make magnet piece 8 attract placing piece 4, from this further promotion place the anti-drop effect of piece 4, place piece 4 promptly more stably.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
