Description

Routing clamp

Technical Field

The invention relates to the technical field of teaching instruments, in particular to a pair of routing pliers.

Background

The information communication socket and the module are nested together, a network cable (or an audio cable) buried in a wall or a wiring cabinet is connected with an external network cable (or a telephone line) through the information communication module, and 8 core wires (or a plurality of core wires of the audio cable) of the network cable are clamped into corresponding wire slots of the information communication module according to the specification in the connection between the information communication module and the network cable (or the audio cable) in the wall and the wiring cabinet. The wire clamp is a special wire clamping tool used when a network cable (or a telephone line) is clamped, generally, when a core wire is clamped into a corresponding wire slot, a longer core wire is usually required to be reserved, and after the core wire is clamped in place, a blade of a wire cutter on the side of the wire clamp is used for cutting off the redundant core wire.

Most of the existing wire pliers are designed as shown in fig. 1, namely, a clamping pressure head 1 for clamping a core wire into a wire slot and a wire cutter 2 for cutting off redundant core wires are integrally arranged, and the wire cutter 2 is arranged in a protruding manner relative to the clamping pressure head 1 for ensuring that the wire cutter can smoothly cut off the core wires. In the practical training operation, the knife edge of the wire cutter protrudes outwards, so that the scratch of students is easily caused, and in addition, the scratch of the wire pliers caused by the slipping of the wire pliers during the wire pressing is occasionally caused due to the fact that part of students are not skilled in the operation of the wire pliers, and the operation ability of the students is uneven. Therefore, a wire bonding pliers capable of effectively avoiding scratches in the teaching process is needed.

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 is reasonable, satisfying teaching under the real circumstances of instructing the requirement, can effectively avoid the fish tail of wire cutter, is favorable to improving the routing pincers of teaching safety in utilization.

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

a routing clamp comprises a handle for holding, and a clamping pressure head and a routing cutter which are axially installed at the front end of the handle, wherein the end part of the clamping pressure head is flat, and the middle part of the clamping pressure head is provided with a groove which is arranged corresponding to a wire groove; the wire cutter is positioned on one side of the flat end part of the clamping and pressing head and is vertical to the end; the clamping and pressing head is characterized in that one end of the clamping and pressing head, which faces the handle, is provided with a guide post, the handle is provided with a guide hole which is arranged corresponding to the guide post, and the guide post is telescopically arranged in the guide hole; the wire cutter is fixedly arranged on the handle; the guide post is sleeved with a return spring, so that the end part of the clamping pressure head is outwards protruded relative to the wire cutter; the minimum elastic force of the reset spring is greater than the maximum clamping resistance of the core wire and the wire groove, and the reset spring can contract under external force, so that the end part of the clamping pressure head retracts inwards relative to the wire cutter.

In the structure, the card pressure head is under reset spring's effect, relative tangent line sword is outwards outstanding, make the edge of a knife of tangent line sword inwards shrink, thereby can effectively avoid the unexpected fish tail of tangent line sword, and because reset spring's minimum elasticity is greater than the biggest joint resistance of heart yearn and wire casing, can enough guarantee smoothly impress the heart yearn in the wire casing, can also guarantee in case when the tangent line sword slippage, under reset spring's elastic action, the card pressure head can not retract easily and make the tangent line sword outstanding, and cause unexpected fish tail, the security of using is improved.

Furthermore, two sides of the flat end part of the clamping and pressing head are respectively provided with a protection part symmetrically extending along the thickness direction of the end, and the width of the protection part is larger than that of the wire cutter.

Like this, when the tip of card pressure head was outstanding relatively to the thread cutter, because the width of guard portion is greater than the width of thread cutter, can avoid the knife point portion of thread cutter to evade the evagination, further improve the security of using. In addition, because the two sides of the flat end part are respectively provided with the protective part, the end part of the card pressing head forms an H-shaped structure, and the strength of the card pressing head can be improved.

Furthermore, one side of the wire cutter, which faces the clamping pressure head, is provided with a guide edge which is arranged in a protruding mode, the clamping pressure head is provided with a guide groove which is matched with the guide edge, and the end part of the guide edge is in an isosceles trapezoid shape, the upper bottom of the isosceles trapezoid shape is arranged in the direction of the wire cutter; and the guide edges on the thread cutting knife are in sliding fit with the guide grooves on the clamping and pressing head.

Like this, be isosceles trapezoid's direction arris and assorted guide way sliding fit through the tip for outside tangent line sword and card pressure head slided relatively in the axial, all restrict each other in other directions, thereby avoid repetitious usage back, the tangent line sword is outside bending deformation under the pushing and shoving effect of heart yearn, influences the cutting performance of tangent line sword.

Furthermore, the wire cutter is also provided with a guard plate, the guard plate is arranged on one side of the wire cutter, which is far away from the clamping pressure head, and the lower end of the guard plate is bent towards the clamping pressure head to be L-shaped and is shielded on the edge of the wire cutter; the middle part of the lower end of the guard plate is provided with a yielding groove which is arranged corresponding to the upper line pressing part of the clamping pressing head, so that the core wire can be contacted with the knife edge of the line cutter through the yielding groove.

By adopting the structure, the knife edge of the thread cutter is shielded by the L-shaped bent guard plate, the phenomenon that the knife edge hurts people due to accidental shrinkage of the clamping pressure head can be avoided, and meanwhile, the abdicating groove is formed in the lower end of the guard plate, so that the cutting-off effect of the knife edge of the thread cutter on the core thread can be reserved.

Further, the guide post is a polygonal column.

Like this, can prevent that the card pressure head from rotating at flexible in-process, change the position relation between card pressure head and the tangent line sword, influence line ball and tangent line operation.

Further, be used for the installation in the handle the cavity of guide post, the guide hole is located the bottom of cavity, the guide post passes the guide hole, and deviates from the one end of card pressure head is passed through separation blade and bolt and is installed the guide hole orientation one side of cavity.

In conclusion, the wire cutting knife has the advantages that the structural design is reasonable, the scratch of the wire cutting knife can be effectively avoided under the condition that the teaching practical training requirement is met, the teaching use safety is favorably improved, and the like.
