Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1-2, the present embodiment discloses a wire insulation stripping tool, which mainly includes a chuck 1 for passing a wire, the chuck 1 has a through hole for passing a power supply wire therethrough, the through hole has a plurality of clamping mechanisms arranged annularly, the clamping mechanisms include a clip 401, a spring 402, and a sliding rod 403, wherein the clip 401 is hinged in a cavity of the chuck 1 communicating with the through hole and is formed by bending a steel strip, one side of the clip 401 extends out of the cavity and extends into the through hole, the other side of the clip 401 is hinged with one end of the sliding rod 403, a position between two sides of the clip 401 is hinged in the cavity, and the hinge point serves as a fulcrum of a lever motion. The other end of the sliding rod 403 can slidably extend out of the chuck 1, that is, the sliding rod 403 can extend out/retract from the side wall of the cavity of the chuck 1, and the spring 402 is sleeved on the portion of the sliding rod 403 located in the cavity, and the sliding rod 403 can make the spring 402 extend and retract along the sliding rod 403 as much as possible and avoid being crushed in an accidental situation. The spring 402 is connected to the cavity side wall and the clip 401, the spring 402 makes one side of the clip 401 with the blade structure incline towards the center of the port at one end extending out of the perforated power supply line under the non-working state, the free ends (namely the blade structures) at one side of the clips 401 extending into the perforation of all the clamping mechanisms are mutually closed to form a notch for clamping and cutting the electric wire, namely wedging and cutting force of the clip 401 on the insulating layer of the electric wire, when in use, the cable passes through the notch after passing through the perforation and extrusion, because the blade structures of all the clips 401 incline towards the port, a barb structure is formed, so that the cable passes through the perforation of the chuck 1 smoothly, but when in withdrawal, because of the elastic resistance of the spring 402, the side of the clip 401 extending into the perforation needs to move towards the direction departing from the port difficultly, namely, only unidirectional movement of the cable can be realized, thereby firmly grasping the head of the cable and cutting into the insulating layer at the corresponding part of the, And stripping off. Further, in order to allow the clamping piece 401 to be manually adjusted in position and protect the spring 402 from being excessively compressed, the extension of the sliding rod 403 of the clamping head 1 has a bottleneck-shaped threaded structure, a bottle cap-shaped locking screw 404 is screwed on the threaded structure, and the bottom of the locking screw 404 has a threaded hole which is matched with the threaded section of the sliding rod 403 extending out of the clamping head 1, so that the sliding rod 403 moves towards the outside of the clamping head 1 when the locking screw 404 is screwed. During adjustment, a user can select to hold the sliding rod 403 by hand to pull out or push the sliding rod 403 to a proper position, and then independently rotate the locking screw cap 404 to cover the threaded structure to lock the position of the sliding rod 403 at the moment, so that when a cable insulation layer is clamped and cut, the position of the clamping piece 401 can not change under a large extrusion force, namely, the clamping stability is ensured. Or, directly screwing the locking screw cap 404, since the sliding rod 403 is movably connected, when the locking screw cap 404 rotates, the sliding rod 403 will also move axially relative to the locking screw cap, so as to achieve the extension/retraction of the sliding rod 403. When the cable insulating layer is thin and the texture is soft, the wedging force of the blade structure required by the cable insulating layer is not large, the cable insulating layer can be realized by only depending on the elastic force of the spring 402, the locking screw rod is screwed off, and at the moment, the sliding rod 403 is not restricted by the locking screw cap 404 and slides out of the chuck 1 in a self-adaptive manner under the action of the clamping piece 401.
In order to achieve a pulling force that pulls the wire outward from the perforation when the insulation is stripped during cutting, this embodiment is characterized in that a supporting pulley 6 is installed at the entrance end of the perforation and a roller 5 for winding the wire is arranged outside the chuck 1, as shown in fig. 1, and the wire is wound on the roller 5 for a plurality of turns, then wound to the lower side of the supporting pulley 6, and then enters the entrance end of the perforation upward and finally protrudes through the cut by being pressed by all the clamping pieces 401. When using, rotate the crank on the cylinder 5, be about to the electric wire towards the direction rotation of accomodating on the cylinder 5, make the electric wire outwards draw and do not rub with the perforation inner wall in the perforation under the assistance of supporting pulley 6 for the insulating layer of electric wire is cut off, takes off. Different cable insulation layers correspond to different pulling forces, and for the torque of the roller 5, the material of the insulation layers is considered to apply, so that when the torque is too small, only the electric wire can be grasped, but cutting cannot be realized, and at the moment, only the grasping function is realized.
As a specific embodiment, in order to improve the cutting performance and enhance the chip removal effect, as shown in fig. 3, a groove 4011 is formed on a surface of one side of the blade back of the blade structure of the clamping piece 401, and during cutting, the insulating chips collide with the bottom of the groove 4011 to form a coil, so that the insulating chips are prevented from being completely clamped in the groove or a through hole, and the cutting has a concentrated moving direction; further, for strengthening the above effect, as shown in fig. 4, the arc-shaped chip blocking plate 4012 is integrally arranged on the side wall of the groove 4011 far away from the electric wire, the arc-shaped profile of the bottom of the chip blocking plate 4012 and the groove 4011 is concentric, and the chip blocking plate 4012 does not interfere with the chuck 1 during the rotation of the clamping piece 401, so that the strip-shaped cutting is led to be removed along the blocking direction of the groove 4011 through the chip blocking plate 4012, the cutting is further prevented from entering the concave cavity or the through hole, and the cutting performance and the chip removal effect are greatly optimized.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
