[0109] In the present utility model, the specific implementation is as follows: Figures 14a to 14c , Fig.15 As shown, a vertically penetrating tool holder mounting threaded hole 801 is respectively provided at the front and rear ends of the left side of the tool holder 8;

[0110] A guillotine installation groove 802 is provided in the longitudinal middle of the tool holder 8 and is vertically penetrated and horizontally distributed;

[0111] The right side of the guillotine installation slot 802 is open (specifically, the right side is completely open);

[0112] In specific implementation, the left side of the guillotine installation slot 802 is also provided with an installation slot inclined surface 803, so that the guillotine 9 can be lifted to a sufficient extent when in use, so as to place the wire trough 1;

[0113] Furthermore, the height of the installation groove inclined surface 803 gradually increases as the lateral distance from the U-shaped frame 7 increases.

[0114] In specific implementation, the right end of the tool holder 8 is provided with a guillotine installation threaded hole 806, a screw through hole 805 and a U-shaped screw countersunk hole 804 which are distributed from front to back;

[0115] The U-shaped screw countersunk hole 804 is vertically connected to the guillotine installation slot 802 through the longitudinally distributed screw through holes 805;

[0116] Furthermore, the guillotine mounting threaded hole 806 and the screw through hole 805 are located on the same longitudinal axis.

[0117] For specific implementation, see Fig.16 , the guillotine 9 is hinged to the tool holder 8 through the guillotine connecting screw;

[0118] The left end of the guillotine 9 is provided with a guillotine mounting hole 901 which runs through longitudinally;

[0119] The left end of the guillotine 9 is placed in the guillotine installation slot 802;

[0120] The guillotine connecting screw passes through the U-shaped screw countersunk hole 804, the screw through hole 805 and the guillotine mounting hole 901 from the back to the front, and is threadedly fixedly connected with the guillotine mounting threaded hole 806;

[0121] Furthermore, there is a clearance fit between the guillotine connecting screw and the guillotine mounting hole 901 .

[0122] It should be noted that, for the present invention, when the guillotine 9 is turned around the guillotine connecting screw and can be lifted up to the maximum extent, the installation groove inclined surface 803 of the tool holder 8 abuts against the guillotine limiting surface 902 of the guillotine 9 located at the upper left corner.

[0123] In specific implementation, the lower part of the guillotine 9 is provided with a transversely distributed long blade 903 for cutting the wire trough 1;

[0124] The right end of the guillotine 9 is fixedly connected to the left end of the handle 904;

[0126] Furthermore, the handle 904 is bolted to the right end of the blade back 906 at the upper part of the guillotine 9 through two handle fastening screws.

[0127] In the present utility model, the specific implementation is as follows: Fig.11 As shown, the bent plate 6 includes a lower table 601 and a vertical surface 603;

[0128] Between the lower surface 601 and the vertical surface 603 of the bent plate 6, a reinforcing rib 604 is provided to increase the strength of the bent plate 6.

[0129] In specific implementation, multiple pairs of U-shaped frame installation holes with different heights (such as h1, h2, h3, etc.) are distributed on the upper part of the facade 603, which are used to install the U-shaped frame holes 701 with a height of h on the U-shaped frames 7 used for the wire ducts 1 of different specifications;

[0130] Each pair of U-shaped frame mounting holes includes two U-shaped frame mounting holes 605 that are symmetrically distributed front and back;

[0131] It should be noted that, for the present invention, the height h of the U-shaped frame hole 701 is slightly higher than the height b of the wire trough 1 by 5 mm, and h1 (or h2, h3) = h + 2 mm (wall thickness of the wire trough 1) + 1 mm;

[0132] In the present invention, in a specific implementation, the U-shaped frame 7 is a part formed by bending a metal sheet, and its shape is similar to the inner cavity 104 of the wire trough 1 and slightly smaller (for example, the dimensions of the U-shaped frame are: c-1mm, d-1mm, b1-0.5mm, b2-0.5mm);

[0133] It should be noted that, for the present invention, a series of U-shaped frames 7 of different sizes can be manufactured according to different sizes of the cable duct 1, and the U-shaped frame holes 701 provided at the upper part are installed between two horizontally distributed bent plates 6;

[0134] In specific implementation, two U-shaped frame holes 701 symmetrically distributed front and back are respectively provided at the upper ends of the left and right sides of the U-shaped frame 7;

[0135] The U-shaped frame 7 is fixedly connected to the vertical surface 603 of the adjacent bent plate 6 by means of a limit screw 12;

[0136] The limiting screw 12 passes through the U-shaped frame mounting hole 605 on the vertical surface 603 and the U-shaped frame hole 701 on the U-shaped frame 7 in sequence, and is then threadedly fixedly connected with a limiting nut.

[0137] In a specific implementation, the upper plane of the pad 5, the bent plates 6 installed at the left and right ends thereof, and the U-shaped frame 7 installed between the bent plates 6, together surround and form a longitudinally penetrating wire slot gap 13;

[0138] The wire trough gap 13 is used to place the wire trough 1 that needs to be cut;

[0139] It should be noted that, for the present invention, the cross-sectional shape of the wire slot gap 13 is similar to that of the wire slot 1 and is slightly larger by 1 mm.

[0140] In specific implementation, a limiting shaft 1201 is provided in the middle of the limiting screw 12;

[0141] It should be noted that the size of the limit shaft 1201 is comparable to that of the U-shaped frame mounting hole 605;

[0142] The length of the limiting axis 1201 is k;

[0143] The right part of the limit screw 12 is provided with a limit thread end 1202;

[0144] It should be noted that the size of the limiting thread end 1202 is comparable to that of the U-shaped frame hole 701 and is slightly smaller than the diameter of the limiting shaft 1201 by 2 mm;

[0145] It should be noted that after the limiting thread end 1202 of the limiting screw 12 passes through the U-shaped frame mounting hole 605 and the U-shaped frame hole 701, it is tightened by a limiting nut and maintains a fixed distance k′ between the U-shaped frame 7 and the upper end of the bent plate 6, so k′=k; that is, the size of the wire trough gap 13 is guaranteed by k′.

[0146] In order to more clearly understand the technical solution of the utility model, the specific working process of the utility model is described below.

[0147] When the device of the utility model is not in use, the guillotine 9 is placed horizontally, the handle falls on the upper plane of the base 4, the elbow 1003 of the safety lever 10 is perpendicular to the guillotine 9, and the lever slot 1004 is stuck on the blade back 906 to prevent safety accidents when the device is not in use.

[0148] When the device of the utility model needs to cut the wire groove 1, first, the device is placed on a horizontal workbench, the elbow 1003 of the safety lever 10 is pulled upward, the slot 1004 is disengaged from the knife back 906, and the safety lever 10 is rotated to make the elbow 1003 horizontal. After releasing, the safety lever 10 will press the base 4 under the action of the compression spring 11 to prevent axial rotation, and the guillotine 9 is lifted upward to turn to the maximum angle (to prevent the guillotine from automatically falling, the maximum angle is greater than 90 degrees), and the installation groove inclined surface 803 of the tool holder 8 is against the guillotine limit surface 902 of the guillotine 9;

[0149] Then, according to the specifications and dimensions of the wire trough 1 to be cut, adjust the front and rear pairs of bent plates so that the lateral distance (i.e., spacing) between each pair of bent plates 6 is equal to a+1mm, and the front and rear pairs of bent plates have the same longitudinal positions, select the U-shaped frame mounting holes 605 of the corresponding height, install the two c-1mm U-shaped frames 7 between the front and rear pairs of bent plates 6 through the limiting screws 12, and tighten the limiting nuts on the limiting threaded ends 1202 of the limiting screws 12;

[0150] Then, pass one end of the wire duct 1 through the wire duct gap 13 from the back to the front, use a tape measure to measure the required cut length L from the front to the back, align it with the position of the cutting surface of the guillotine 9, lift the handle 904 and rotate to cut the wire duct 1, and the wire duct 1 can be cut to the required length L, cut more wire ducts 1, and repeat the above operation;

[0151] In addition, if it is necessary to cut the cable duct 1 of different specifications, it is only necessary to adjust the horizontal distance between the two bent plates and then replace the corresponding U-shaped frame 7.

[0152] Compared with the prior art, the wire groove cutting device provided by the utility model has the following beneficial effects:

[0153] 1. The structure combining the bent plate, the U-shaped frame and the pad is used to restrict the non-rigid workpiece to be cut (i.e., the wire groove) to a rigid gap (i.e., the wire groove gap 13), thus overcoming the problem of irregular cutting surface of non-rigid deep groove workpieces;
