The invention relates to a decoration tool, particularly to a pair of novel special multifunctional nipper pliers for decoration. The pair of novel special multifunctional nipper pliers comprises a nipper plier body I, a nipper plier body II, a rotating connecting piece, a turning connecting piece, a handle body I, a handle body II, an inlay fixing central shaft, a phillips screwdriver, track grooves, a locating block, a cutter fixing clamp and hand protecting rubber pads. The pair of novel special multifunctional nipper pliers has three functions, the tool carrying amount of staff is decreased, time of staff is saved, working efficiency is improved, the structure is simple, and operation is convenient; the nipper plier body I and the nipper plier body II are matched through a groove; thenipper plier body I and the nipper plier body II are in tight contact connection through the inlay fixing central shaft; the track groove is formed in the handle body I; the locating block and the turning connecting piece are in movable contact connection through a groove; the track groove is formed in the handle body II; the hand protecting rubber pads are arranged on the handle body I and the handle body II; and the cutter fixing clamp meshes with the phillips screwdriver through threads.

The invention provides a nut cover pulling-out device, which comprises a clamping sheet. The clamping sheet is elastic and is of a U-shaped structure; the inner wall of a first vertical sheet of the clamping sheet is provided with a first clamping boss used for being clamped into an annular groove in the outer surface of a nut cover, and the inner wall of a second vertical sheet of the clamping sheet is provided with a second clamping boss used for being clamped into the annular groove; and the first clamping boss and the second clamping boss are opposite and are both arranged close to an opening of the clamping sheet. According to the nut cover pulling-out device, the first clamping boss and the second clamping boss are clamped into the annular groove in the outer surface of the nut coverinstead of being matched with the smooth outer surface on the nut cover, thus the clamping sheet and the nut cover are reliably matched, the problem that nipper pliers are prone to sliding from the nut cover is effectively avoided, and then the nut cover is conveniently pulled out.

An easily disassembled impeller-type flow sensor, comprising a housing and an impeller-type sensor assembly, the housing includes an impeller chamber, a water inlet port communicated with the impeller chamber, a water outlet port communicated with the impeller chamber, and a water outlet port communicated with the impeller chamber The assembly seat of the base also includes an open retaining ring, the part of the lower part of the steps of the base is liquid-tight with the assembly seat at the lower part of the inner ring platform, and the steps are supported and matched with the inner ring platform; the radially outer side of the open retaining ring is embedded in the ring The inside and the radial inner side of the card slot cooperate with the radial edge of the top of the base. Due to the adoption of such a structure, when the impeller sensor assembly is disassembled, especially in the environment where the pipeline is densely covered and a wrench cannot be used, it is only necessary to disassemble the opening retaining ring with bare hands or needle-nose pliers; and then it can be removed by hand without any tools. The impeller sensor assembly is taken out and disassembled easily. When assembling, just insert the impeller assembly into the impeller chamber with bare hands, and then assemble the opening retaining ring, which is convenient for assembly.

The invention provides a detachable expansion bolt sleeve. The detachable expansion bolt sleeve comprises a sleeve section and an expansion section, wherein an extending section which extends outwardsin the direction of the sleeve bus is arranged at the outer end of the sleeve. During mounting, the expansion bolt sleeve is inserted into a mounting hole until the required depth is reached, and theextending section of the sleeve is bent outwards by 90 degrees by hand or by means of a tool, so that a second bending section is attached to a mounting wall body or the ground, the depth and the rotation of the sleeve can be controlled and limited in the follow-up screwing process of a nut of the expansion bolt. During dismounting, the nut is screwed down and the bolt is knocked, and then the second bending section is raised up or pried, so that a clamping point at the tail end of the extending section is conveniently and stably clamped through a vice or sharp-nose pliers, and the sleeve ispulled out from the mounting hole. According to the detachable expansion bolt sleeve, the existing sleeve production process is not changed, the production process is not increased, and the detachableexpansion bolt sleeve can be produced only by changing the cutting size or a stamping die of the sleeve in the existing production process, so that the cost can not be additionally increased comparedwith an existing product.

The invention belongs to the technical field of wire bending pliers, and in particular to a convenient-to-adjust wire bending pliers, which comprise a needle-nose pliers, an inverted L-shaped press head is sleeved on a left jaw, the lower end surface of the inverted L-shaped press head is provided with a first frustum blind hole which matches the upper end of the left jaw, the right end surface ofthe inverted L-shaped press head is provided with an arc-shaped gap, a rectangular block is sleeved on a right jaw, the lower end surface of the rectangular block is provided with a second frustum blind hole which matches the upper end of the right jaw, the upper portion of the front end surface of the rectangular block is provided with a rectangular hole, the right end surface of the rectangularblock is provided with a first stepped hole at a position corresponding to the rectangular hole, a clamping block is fixed at one end of each rack, one end, which is close to the inverted L-shaped press head, of the side of each clamping block is provided with a V-shaped notch, one end, which is far from the inverted L-shaped press head, of the side of each clamping block is provided with a rectangular notch which matches the other rack, and the right end of a first hexagonal prism passes through the first stepped hole and is connected to a rotary disk. The objective of the invention is to solve the problems of inconvenience in carrying and use and narrow application range caused by the structural defects of conventional tools for the secondary bending of wires.
