All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "configured," "connected," "secured," "screwed," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intermediaries, or in communication with each other or in interaction with each other, unless explicitly defined otherwise, the meaning of the terms described above in this application will be understood by those of ordinary skill in the art in view of the specific circumstances.

Examples

Referring to fig. 1 to 4, in the embodiment of the utility model, a fastening bolt comprises a cap head 1, a flange plate 2 is integrally connected to the bottom of the cap head 1, a connecting rod 3 is integrally connected to the bottom of the flange plate 2, a hexagonal clamping groove 4 is formed in the top of the cap head 1, an inner opening 5 is formed in the bottom of an inner cavity of the hexagonal clamping groove 4, a chuck 6 is clamped in the inner cavity of the inner opening 5, a short rod 7 is integrally connected to the bottom of the chuck 6, a stop lever 8 is welded around the bottom of the short rod 7, a sliding opening 9 is formed in the surface of the connecting rod 3, the surface of the stop lever 8 penetrates through the sliding opening 9 and extends to the outside, a rectangular block 10 is welded at the corresponding position of the stop lever 8, a clamping piece 11 is hinged to the inner side of the rectangular block 10, a clamping tooth 12 is integrally connected to one side of the top of the clamping piece 11, and a screw rod 13 is integrally connected to the bottom of the connecting rod 3.

The diameter of lead screw 13 is greater than the diameter of connecting rod 3, the length of card 11 is greater than the diameter length of lead screw 13, because the diameter of lead screw 13 is greater than the diameter of connecting rod 3, so lead screw 13 when the external screw hole inner chamber of external object seting up is twisted in, card 11 can rotate to the position in the lead screw 13 diameter to cap 1 direction, and then can not influence the use of lead screw 13, because the length of card 11 is greater than the diameter length of lead screw 13, so lead screw 13 is because of external influence when outwards removing, card 11 and latch 12 cooperation can with the external object seting up the screw thread of external screw hole inner chamber block, and then prevent lead screw 13 not hard up.

The bottom joint in hexagonal draw-in groove 4 inner chamber has hexagonal fastener 14, and the bayonet socket has been seted up at the top of chuck 6, and the joint in the inner chamber joint of hexagonal fastener 14 and bayonet socket is spacing chuck 6 through hexagonal fastener 14, makes it unable rotation, and then carries out spacing fixedly to pin 8.

The top joint of the cap head 1 is provided with a heat shrinkage sleeve 15, the heat shrinkage sleeve 15 is formed by compounding a radiation crosslinking polyolefin substrate and a special sealing hot melt adhesive, the heat extraction sleeve is radially shrunk, and meanwhile, an inner composite adhesive layer is melted and tightly coated on the cap head 1, so that a firm anti-corrosion body is formed, the cap head 1 is protected, and meanwhile, the hexagonal clamping piece 14 can be limited and fixed.

The bottom of the flange plate 2 is provided with anti-skid patterns 16, and friction force between the flange plate and an external object is increased through the anti-skid patterns 16, so that a certain fastening effect is achieved.

The working principle of the utility model is as follows: the device clamps the chuck 6 into the inner opening 5, clamps the stop lever 8 on the corresponding short rod 7 in a welding mode, clamps the hexagonal clamping piece 14 into the inner cavity of the bayonet on the chuck 6, fixes and limits the chuck 6, when the bolt is used, inserts the screw rod 13 into the external threaded hole corresponding to the external object, clamps the output end of the external hexagonal wrench into the inner cavity of the hexagonal clamping groove 4, screws the screw rod 13 into the threaded hole through rotating the external hexagonal wrench, because the clamping piece 11 and the rectangular block 10 are in hinged connection, the diameter of the connecting rod 3 is smaller than the diameter of the screw rod 13, the clamping piece 11 can be turned to a position in the diameter of the screw rod 13 towards the direction of the cap head 1 when the screw rod 13 is screwed into the external threaded hole, further the clamping tooth 12 can not be clamped with the threads of the inner cavity of the external threaded hole, so that the screw rod 13 can be screwed into the corresponding external threaded hole, and further the corresponding external object can be fixed, after the screw rod 13 is completely screwed into the external threaded hole, the clamping piece 11 and the clamping tooth 12 are in threaded contact with the external threaded hole, when the screw rod 13 is impacted by vibration and moves outwards, the clamping tooth 12 is clamped with the threads of the internal cavity of the external threaded hole, and further the screw rod 13 is prevented from moving outwards, because the stop lever 8 is positioned at the bottom of the clamping piece 11 and can play a supporting and limiting role, when the screw rod 13 moves outwards in a rotating way, the clamping piece 11 and the clamping tooth 12 cannot be turned over towards the direction of the screw rod 13, and then the clamping tooth 12 is clamped with the threads of the internal cavity of the external threaded hole to form resistance, so that the bolt cannot fall off from the external threaded hole formed by an external object, when the screw rod 13 needs to be unscrewed, the heat shrinkage sleeve 15 is removed, then the hexagonal clamping piece 14 is taken out, the bayonet on the rotating chuck 6 drives the short rod 7 and the stop lever 8 to rotate to the other side of the sliding port 9, at this time, when the screw rod 13 rotates outwards, the card 11 and the latch 12 lose the resistance supported by the stop lever 8 and turn to the position in the diameter of the screw rod 13 towards the direction of the screw rod 13, so that the latch 12 cannot form resistance with the threads in the inner cavity of the external threaded hole, and the screw rod 13 can be screwed out of the external threaded hole formed by an external object.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
