Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, a replaceable anti-theft nut includes a screw rod 1 and a nut 2 in threaded connection with the screw rod 1, the outer wall of the screw rod 1 is circular, which is inconvenient to disassemble and has an anti-theft effect, a hole 311 is formed in the outer wall of the screw rod 1, an insertion rod 312 is inserted into the hole 311, the insertion rod 312 can be inserted into the hole 311, and the effect of rotating the screw rod 1 is achieved. The hole 311 and the insertion rod 312 are matched with each other, and the hole 311 and the insertion rod 312 are hexagonal prisms, so that the insertion rod 312 cannot rotate inside the hole 311, the normal rotation of the screw 1 is affected, and the operation is more stable. The baffle 313 is fixedly connected to one end, far away from the hole 311, of the insertion rod 312, the diameter of the baffle 313 is larger than that of the insertion rod 312, and the baffle 313 can be arranged to enable the insertion rod 312 and the screw 1 to be rotated more conveniently, so that operation is simpler and more convenient.

Fixed block 411 is fixed to the outer wall of screw 1, cavity 412 has been seted up inside the fixed block 411, the inside kelly 413 that is provided with of cavity 412, draw-in groove 415 with kelly 413 mutual matching is seted up to inserted bar 312 bottom, the inside expanding spring 414 that is provided with of cavity 412, expanding spring 414 one end is connected in kelly 413, the other end is connected in cavity 412 inner wall, it inserts inside cavity 412 to make it insert behind the kelly 413 to press, and drive expanding spring 414 compresses, insert inside hole 311 with inserted bar 312 afterwards, after loosening kelly 413, can drive inside kelly 413 inserts draw-in groove 415 under expanding spring 414's elasticity reset action, avoid inserted bar 312 to break away from with hole 311, reach further limiting displacement. The lateral wall of the fixing block 411 is provided with a slot 417, the outer wall of the clamping rod 413 is fixed with a pushing plate 416 corresponding to the slot 417, the pushing plate 416 can slide along the inner wall of the slot 417 and drive the clamping rod 413 to vertically reciprocate, the mode is more convenient to operate, and the using effect of the device is enhanced.
