[0003] The existing tool for assisting secondary wiring has the following shortcomings: (1) the existing tool for assisting secondary wiring uses a screw rod to compress and fix the cable, and the fixing function is weak, and the cable will slide due to the rotation stress of the cable itself during use, which will cause inconvenience to the operation of the workers; (2) the existing tool for assisting secondary wiring has weak butt joint function, and cannot adjust the sliding of the cables to be butt jointed on both sides according to the needs, so as to realize quick butt joint and improve the wiring efficiency. UTILITY MODEL CONTENTS

[0004] The utility model intends to provide a tool for assisting secondary wiring, so as to provide a wiring tool with better fixing effect and convenient adjustment.

[0005] In order to solve the above problems, the utility model provides the following technical scheme:

[0006] A tool for assisting secondary wiring, comprising a bottom plate, the bottom plate is symmetrical with a sliding groove group along its axis, each sliding groove group comprises a sliding groove which is symmetrical and fixedly arranged along the axis of the bottom plate, a fixing seat is slidably connected between the two sliding grooves on the same side through a sliding block, a plurality of fixing holes are arranged in the sliding groove along the sliding direction of the sliding groove, the sliding block is provided with a threaded hole which is opposite to the corresponding fixing hole, and the threaded hole and one of the fixing holes are fixed through a fixing screw; each fixing seat is provided with a plurality of placing grooves, the fixing seat is hingedly connected with a cover plate, the cover plate and the fixing seat are fixed through a bolt, the cover plate is threadedly connected with a compression screw which is matched with each placing groove respectively, and the bottom of the placing groove is provided with an arc-shaped convex rib which is opposite to each compression screw.

[0007] Working principle and beneficial effects of the utility model:

[0008] The cover plate is opened, the cables to be connected are placed in the corresponding placing grooves, then the cover plate is buckled, the cover plate and the fixing seat are connected by using the bolts to fix the cover plate, then the cable is pressed between the arc-shaped convex edges and the pressing screw by rotating the pressing screw towards the placing groove. After the cable is fixed, the fixing seats on both sides are slid to move relatively, so that the cables on both sides are connected to each other. At this time, the threaded hole on the sliding block and the opposite one of the fixing holes are opposite and connected, and the fixing screw is screwed in, so that the sliding block and the fixing seat are fixed, and the next step of the connected cable can be performed.

[0009] Firstly, the cable is pressed by the arc-shaped convex edges and the pressing screw, the area of the arc-shaped convex edges is small, so that the pressing force is more concentrated and larger, thereby improving the fixing effect of the cable and effectively solving the problem that the self-rotating stress of the cable causes the cable to slide. Secondly, the fixing seats on both sides are slid, and then the fixing screw is used to fix, so that the cables to be connected on both sides are slid and adjusted, thereby realizing rapid alignment and improving the wiring efficiency.

[0010] In some embodiments, the placing groove is a circular groove. The shape of the circular groove better fits the surface of the cable, and plays a role in auxiliary fixing and positioning.

[0011] In some embodiments, the bottom edge of the bottom plate is fixedly connected with a support column, and the bottom of the support column is fixedly connected with a base. The support column and the base provide stability for the device.

[0012] In some embodiments, the pressing screw is coaxially and rotatably connected with a pressing plate opposite to the arc-shaped convex edge. When the pressing screw is rotated in, the pressing screw pushes the pressing plate downwards to move towards the cable, and finally presses the cable between the pressing plate and the arc-shaped convex edge.

[0013] In some embodiments, the cover plate is fixedly provided with a limiting rod, and the pressing plate is provided with a limiting hole penetrating through the limiting rod. When the pressing screw is rotated in, the limiting rod can prevent the pressing plate from rotating through the limiting hole.

[0014] In some embodiments, the vertical cross-sectional shape of the pressing plate is semicircular. The shape improves the pressing force. BRIEF DESCRIPTION OF DRAWINGS

[0022] The following will be further described in detail through specific embodiments:

[0023] The reference signs in the drawings of the specification include: bottom plate 1, fixing hole 2, fixing seat 3, cover plate 4, fixing screw 5, base 6, support seat 7, sliding groove 8, cable 9, pressing screw 10, threaded hole 11, sliding block 12, placing groove 13, arc-shaped convex rib 14, pressing plate 15, bolt 16, limiting hole 17, limiting rod 18.

[0024] The orientation words such as “left”, “right”, “up”, “down” and the like in the following statements are based on the orientation of the drawings, and in actuality, if the corresponding structures are changed in the same direction based on the orientation and the relative positions remain unchanged, it does not affect the implementation of the scheme.

[0025] Example 1: a secondary wiring auxiliary tool, as shown in Figure 1 , includes a bottom plate 1, and the bottom of the bottom plate 1 is fixedly connected with a base 6 through a support seat 7, and stable support is achieved by using the support seat 7 and the base 6.

The sliding groove 8 is provided with eight fixing holes 2 communicated with the sliding grooves along the sliding direction of the sliding groove 8, the sliding block 12 is provided with a threaded hole 11 opposite to the corresponding fixing hole 2, and the threaded hole 11 and one of the fixing holes 2 are screwed into a fixing screw 5 for fixation.

[0027] Each fixing seat 3 is provided with six placing grooves 13, and the bottom of each placing groove 13 is fixedly provided with an arc-shaped convex rib 14 opposite to each pressing screw 10.

[0028] The fixed seat 3 is hinged with a cover plate 4, the cover plate 4 and the fixed seat 3 are fixed through a bolt 16, the cover plate 4 is threadedly connected with a compression screw 10 matched with each placing groove 13 respectively, the compression screw 10 is coaxially and rotationally connected with a pressing plate 15 opposite to the arc-shaped convex rib 14, the cover plate 4 is fixedly provided with a limiting rod 18, and the pressing plate 15 is provided with a limiting hole 17 penetrating through the limiting rod 18.
