Technical Field

The invention relates to the technical field of maintenance tools, in particular to an internal and external dual-purpose circlip pliers.

Background

The circlip pliers are divided into circlip pliers for holes (also called inner circlip pliers) and circlip pliers for shafts (also called outer circlip pliers). The clamp spring pliers are used for mounting the inner spring ring and the outer spring ring, and belong to sharp nose pliers in appearance.

The existing circlip pliers are designed into a single head, or an inner caliper or an outer caliper; and when equipment maintenance, both probably need use inside calliper, probably need outside calliper again, for avoiding leaking the area instrument, need carry inside calliper and outside calliper simultaneously usually to cause and carry the inconvenience.

Chinese patent document describes a circlip pliers, application No. 2017211293255, which can be switched between an inner caliper and an outer caliper by a detachable assembly structure, but the circlip pliers have a complicated structure, many parts involved in the assembly and disassembly process, and are complicated to assemble and disassemble, and easily cause loss of parts.

Disclosure of Invention

Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a structural design simple ingenious, dismouting spare part is few, easy dismounting is swift, portable's inside and outside dual-purpose jump ring pincers.

In order to solve the technical problems, the invention adopts the following technical scheme:

the inside and outside dual-purpose circlip pliers comprise a first pliers body and a second pliers body, wherein the first pliers body comprises a first pliers head, a first connecting part and a first handle, and the first handle is arranged on the first connecting part along a direction departing from the first pliers head; the second clamp body comprises a second clamp head, a second connecting part and a second handle, and the first connecting part and the second connecting part are rotatably connected through a hinge shaft; the side surface of the second connecting part, which is far away from the second tong head, is provided with an inner clamp mounting hole and an outer clamp mounting hole, and the second handle is detachably mounted on the inner clamp mounting hole or the outer clamp mounting hole; the inner clamp mounting hole and the outer clamp mounting hole are distributed on two sides of the first handle along the circumferential direction of the hinge shaft, so that the inner clamp mounting hole and the second binding clip are respectively located on two sides of the first handle, and the outer clamp mounting hole and the second binding clip are located on the same side of the first handle.

Adopt above-mentioned structure, when installing the second handle on interior card mounting hole, because interior card mounting hole is located the both sides of first handle respectively with the second binding clip, make second handle and second binding clip and first handle and first binding clip form X alternately, deviate from first handle and second handle mutually and open the time, first binding clip and second binding clip also open, when holding between the fingers first handle and second handle, first binding clip and second binding clip are together closed, thereby can be in order to carry out the dismouting to the both ends pressfitting of spring ring. When installing the second handle on outer calorie of mounting hole, because outer calorie of mounting hole is located same one side of first handle with the second binding clip for when first handle and second handle deviate from mutually and open, first binding clip and second binding clip are closed, and when holding between the fingers first handle and second handle, first binding clip outwards opens with the second binding clip, thereby can strut in order to carry out the dismouting to it at the both ends of external spring ring. The jump ring pincers of this structure only need the dismouting second handle, just can switch the state of inside calliper and outside calliper, and it is few to dismantle spare part, and the volume of second handle is great, dismantles the in-process and is difficult for losing.

Furthermore, the side surface of the second connecting part, which is far away from the second binding clip, is an arc surface which is coaxially arranged with the hinge shaft, and the inner clip mounting hole and the outer clip mounting hole are radially arranged on the arc surface.

Furthermore, a first reset magnet is arranged on the first handle, and a second reset magnet arranged corresponding to the first reset magnet is arranged on the second handle, so that when the second handle is installed on the inner clamp installation hole or the outer clamp installation hole, the homopolar of the second reset magnet is opposite to that of the first reset magnet.

By utilizing the homopolar repulsion between the first reset magnet and the second reset magnet, the first handle and the second handle can be kept in a separated state all the time under the condition of not being kneaded by external force. Therefore, the clamp spring caliper is always in the best use state no matter in the inner caliper state or the outer caliper state. First magnet and the second magnet direct mount that resets on first handle and second handle, when switching jump ring pincers state, need not to carry out the dismouting to first magnet and the second magnet that resets, can guarantee the facility of dismouting, can guarantee again that the use is convenient.

Furthermore, the bottom of the inner clamping mounting hole and the bottom of the outer clamping mounting hole are both provided with first positioning magnets, one end, facing the second connecting portion, of the second handle is provided with an inserting column matched with the inner clamping mounting hole and the outer clamping mounting hole, and the end portion of the inserting column is provided with a second positioning magnet capable of being attracted with the first positioning magnets.

The second handle is matched with the inner clamping mounting hole or the outer clamping mounting hole through the inserting column and is kept fixed through the magnetic attraction of the first positioning magnet and the second positioning magnet, so that the second handle can be rapidly assembled and disassembled with the inner clamping mounting hole or the outer clamping mounting hole.

Furthermore, two second reset magnets are arranged and are respectively positioned on two sides of the second handle, and the magnetic poles of the two second reset magnets face in the same direction; when the first tong head and the second tong head are combined, the second handle arranged on the inner clamp mounting hole is close to the first handle.

The two second reset magnets with the same magnetic pole orientation are respectively positioned at the two sides of the second handle, so that the magnetic pole of the second reset magnet on one side of the second handle is the same as that of the first reset magnet, and the magnetic pole of the second reset magnet on the other side is different from that of the first reset magnet; and the second handle is detachably mounted with the inner clamping mounting hole through the plug-in column. Therefore, the direction of the acting force of the magnet between the first handle and the second handle can be controlled by changing the inserting direction of the second handle, and when the resetting magnet is required to be used as an inside caliper, the second resetting magnet which is arranged on the second handle and has the same magnetic pole with the first resetting magnet faces the first handle, so that the first handle and the second handle are opened under the action of the repulsive force of the magnets. When the clamp spring pincers are required to be stored and placed, the second reset magnet which is arranged on the second handle and has the magnetic poles different from those of the first reset magnet faces the first handle, so that the first handle and the second handle are close to each other under the action of attraction force of the magnets, the clamp spring pincers are integrally contracted, and the clamp spring pincers are convenient to store.

Furthermore, a first attracting magnet is arranged on the first clamp body, a second attracting magnet corresponding to the first attracting magnet is arranged on the second clamp body, the first attracting magnet and the second attracting magnet are oppositely arranged in a manner of attracting magnetic poles in the circumferential direction of the hinge shaft, and the attracting force of the first attracting magnet and the attracting force of the second attracting magnet are smaller than the repulsive force of the first resetting magnet and the second resetting magnet, so that the first handle and the second handle can be kept in an open state under the action of the repulsive force of the first resetting magnet and the second resetting magnet.

Therefore, under the interaction of the attraction force of the first attraction magnet and the second attraction magnet and the repulsive force of the first reset magnet and the second reset magnet, the two handles of the snap spring clamp can still be in a working state under the action of the attraction force under the condition that the two handles are kept in an open state.

Furthermore, the first attracting magnet and the second attracting magnet are respectively arranged on the first handle and the second handle and are respectively positioned at the end parts of the first handle and the second handle close to the hinge shaft.

The first attracting magnet and the second attracting magnet need to be in a certain distance to enable the magnetic fields of the first attracting magnet and the second attracting magnet to interact with each other to generate attracting force, and the first handle and the second handle are close to the end part of the hinge shaft because the end parts of the first handle and the second handle close to the hinge shaft are close to each other, so that the first attracting magnet and the second attracting magnet are guaranteed to generate reliable attracting force.

Furthermore, the inner clamping mounting hole and the outer clamping mounting hole are round holes, the inserting column is a cylinder and is provided with a guide angle at the end part, and the diameter of the inserting column is consistent with that of the inner clamping mounting hole and that of the outer clamping mounting hole.

Therefore, the inner clamping mounting hole, the outer clamping mounting hole and the inserting column can be more conveniently machined, and machining cost is reduced. Simultaneously, when changeing the jump ring pincers to the state of accomodating by the outside calliper state, only need rotate the second handle, change two second reset magnet the position can, convenient operation is quick.

In conclusion, the portable multifunctional electric heating cooker has the advantages of simple and ingenious structural design, few disassembled parts, convenience and quickness in disassembly and assembly, convenience in carrying and the like.
