At the same time, it is convenient to release the decorative lines in time after the cutting is completed to adjust the cutting position. Specifically, in the operation, the electromagnetic The iron body is in a power-off state, and then the distance between the pressing plate and the supporting pad is enlarged by holding the handle to drive the guide stud to rise, and then the decorative line is horizontally passed between the pressing plate and the supporting pad. When the decorative line is horizontally moved to the cutting position and vertically overlapped with the cutting blade, the decorative line is kept stationary, and then the handle is released to allow the pressing plate to naturally drop to press on the top surface of the decorative line. Then, the electromagnet body is energized and the bottom end of the lifting stud is magnetically attracted to make the pressing plate cooperate with the supporting pad to press and fix the decorative line. At the same time, since the lifting stud passes through the wing plate in a threaded engagement manner, the bottom end of the lifting stud and the electromagnet can be adjusted by reversing the lifting stud.

The invention can facilitate the rapid cutting of a plurality of decorative line segments of equal length. At the same time, in the process of lateral sliding of the adjusting stud, the lateral movement of the limit baffle can be guided and constrained by the guide rod sliding horizontally along the guide hole. At the same time, since the surface of the guide rod is printed with the scale markings indicating the distance between the cutting blade and the limit baffle, the distance between the limit baffle and the cutting blade can be accurately adjusted to be consistent with the required length of the decorative line by referring to the scale markings, so as to further facilitate the cutting of a plurality of decorative line segments of equal length. It should be noted that before lateral sliding adjustment of the adjusting stud, the limit nuts at both sides should be kept away from each other and the distance between each other should be enlarged.When the adjusting stud drives the limit baffle to be adjusted to the desired position, the adjusting stud should be kept stationary and the limit nut should be tightened on the side end surface corresponding to the fixed vertical plate to lock the position of the limit baffle and prevent it from moving. Then, after the outer end of the decorative line is against the surface of the limit baffle, the decorative line is pressed and fixed by the line pressing component, and then the electric telescopic rod body and the driving motor of the line cutting component are energized to work, the electric telescopic rod body drives the knife holder and the cutting blade to descend, and the driving motor drives the cutting blade to rotate through the motor shaft, so that the decorative line can be cut by the cutting blade rotating and descending. After cutting, the cutting blade should be returned to the initial height and stop rotating, and the cut decorative line segment should be removed, and then the line pressing component should be released. Then, the decorative line is moved to the outer end to abut against the surface of the limit baffle and the cutting operation is repeated, so as to cut and process multiple decorative line segments of equal length by repeated cutting. During the combination and disassembly operation of the line cutting assembly and the operating table body, when the line cutting assembly is assembled on the top of the operating table body, the line cutting assembly can be detachably fixed to the top position of the operating table body by means of the vertical sliding cooperation between the matching seat and the matching groove and the longitudinal sliding cooperation between the limiting rod and the limiting hole. The fixing and assembly method of the line cutting assembly on the top of the operating table body is simple and easy to operate, which makes it easy to quickly fix the line cutting assembly on the top of the operating table body for use. When the line cutting assembly is disassembled on the top of the operating table body, it is only necessary to hold the pull handle outward and make the limiting rod disengage from the limiting hole by means of the stretching of the spring, and then the matching seat can be vertically disengaged from the matching groove to disassemble the line cutting assembly from the top of the operating table body. The disassembly method of the line cutting assembly on the top of the operating table body is simple and easy to operate, which makes it easy to quickly disassemble the line cutting assembly from the top of the operating table body for regular inspection and maintenance.

Moreover, since the buffer pad 4, the cutting pad 7 and the top surface of the support plate 509 are at the same level, it is ensured that the decorative lines can be in a flat state during the cutting process.

[0052] Specifically, as for the line pressing assembly 1, a handle 101 is fixedly installed on the top of the guide stud 102, so that the guide stud 102 and the pressure plate 106 can be lifted and lowered by applying force with the handle 101. The front and rear end surfaces of the wing plate 105 do not contact the inner surface of the U-shaped mounting seat 103, so as to ensure that the wing plate 105 can be smoothly lifted and lowered with the pressure plate 106. The lifting studs 104 are all hexagonal bolts with flat heads at the bottom. This arrangement facilitates the bottom end of the lifting stud 104 to be stably magnetically attracted to the electromagnet body 107. A control button 108 is installed in front of the U-shaped mounting seat 103, and the control button 108 is electrically connected to the electromagnet body 107 to adjust the on and off state of the electromagnet body 107 through the control button 108. This arrangement facilitates the adjustment of the on and off state of the electromagnet body 107 by setting the control button 108, and then facilitates the adjustment of the pressing state of the line pressing assembly 1.

[0053] See also Figure 1-Figure 11As shown, the line cutting component 8 and the disassembly and assembly component 9 are optimized as follows. Specifically for the line cutting component 8, the cutting blade 801 is a circular blade, the cutting blade 801 is vertically opposite to the object opening 6, and the lateral thickness of the cutting blade 801 is smaller than the lateral thickness of the object opening 6, and the longitudinal diameter of the cutting blade 801 is smaller than the longitudinal width of the object opening 6, so that the cutting blade 801 can smoothly pass through the object opening 6 vertically. This arrangement makes it easy for the lower part of the cutting blade 801 to smoothly pass through the object opening 6, thereby ensuring that the decorative line can be cut. Specifically for the disassembly and assembly component 9, the horizontal cross-sectional shapes of the mating seat 905 and the mating groove 902 are both rectangular, the mating groove 902 is a blind groove in the vertical direction, and the bottom end surface of the mating seat 905 is in close contact with the bottom end surface of the mating groove 902. The advantage of this arrangement is that in the process of the mating seat 905 sliding vertically along the mating groove 902, when the mating seat 905 slides vertically along the mating groove 902 to be longitudinally coaxial with the limiting hole 908 and the limiting rod 907, an obvious prompt can be given by the way that the bottom end surface of the mating seat 905 is in close contact with the bottom end surface of the mating groove 902.

[0054] By adopting the above structure, specifically in the process of cutting the decorative lines, the bottom end of the lifting stud 104 of the line pressing assembly 1 and the electromagnetic body 107 are magnetically attracted to each other, so that the pressing plate 106 can cooperate with the supporting pad 3 to press and fix the decorative lines. The electromagnetic body 107 only needs to be powered off to release the magnetic attraction state with the lifting stud 104, and then the pressing plate 106 can be raised to release the pressing state of the decorative lines. The pressing and releasing methods of the decorative lines are simple and easy to operate, which is convenient for fixing the decorative lines firmly and reliably and preventing the decorative lines from moving around during the cutting process. At the same time, it is convenient to release the decorative lines in time after the cutting is completed to adjust the cutting position. Specifically, in the operation, the electromagnetic body 107 is firstly placed in the In the power-off state, the distance between the pressing plate 106 and the supporting pad 3 is enlarged by holding the handle 101 to drive the guide stud 102 to rise, and then the decorative line is horizontally passed between the pressing plate 106 and the supporting pad 3. When the decorative line is horizontally moved to the cutting position and vertically overlapped with the cutting blade 801, the decorative line is kept stationary, and then the handle 101 is released to make the pressing plate 106 naturally drop to press on the top surface of the decorative line, and then the electromagnet body 107 is energized and the bottom end of the lifting stud 104 is magnetically attracted to make the pressing plate 106 cooperate with the supporting pad 3 to press and fix the decorative line. At the same time, since the lifting stud 104 passes through the wing plate 105 in a threaded engagement manner, the lifting stud 104 can be adjusted by reversing the lifting stud 104. The distance between the bottom end and the electromagnet body 107 ensures that the lifting stud 104 can be adjusted to be stably magnetically attracted to the electromagnet body 107, so that the pressing plate 106 can cooperate with the supporting pad 3 to press and fix decorative lines of different thicknesses, thereby improving the versatility and adaptability of the line pressing component 1. Specifically, as for the cutting limit component 5, since the adjusting stud 504 of the cutting limit component 5 is inserted through the fixed vertical plate 506 in a lateral sliding manner, the distance between the limit baffle 508 and the cutting blade 801 can be adjusted by adjusting the stud 504 to slide horizontally, so that the cutting position of the decorative line can be accurately limited by the end of the decorative line against the limit baffle 508, The limiting method of the line cutting position is simple and easy to operate, which is convenient for quickly cutting and processing multiple decorative line segments of equal length. At the same time, in the process of adjusting the lateral sliding of the stud 504, the lateral movement of the limit baffle 508 can be guided and constrained by the lateral sliding of the guide rod 501 along the guide hole 507. At the same time, since the surface of the guide rod 501 is printed with a scale mark 502 for indicating the distance between the cutting blade 801 and the limit baffle 508, the distance between the limit baffle 508 and the cutting blade 801 can be accurately adjusted to the same length of the decorative line required by referring to the scale mark 502, which further facilitates the cutting and processing of multiple decorative line segments of equal length. It should be noted that before the lateral sliding adjustment stud 504 is adjusted,The limiting nuts 505 on both sides should be moved away from each other and the distance between them should be increased. When the adjusting stud 504 drives the limiting baffle 508 to be adjusted to the desired position, the adjusting stud 504 should be kept stationary and the limiting nuts 505 should be tightened on the corresponding side end faces of the fixed vertical plate 506 to lock the position of the limiting baffle 508 so that it cannot be moved. Then, the outer end of the decorative line should be placed against the surface of the limiting baffle 508, and the decorative line should be pressed and fixed by the line pressing component 1, and then the electric telescopic rod body 804 and the driving motor 806 of the line cutting component 8 should be energized. The electric telescopic rod body 804 drives the knife holder 803 and the cutting blade 801 to descend, and the driving motor 806 drives the cutting blade 801 to rotate through the motor shaft 802, so that the decorative line can be cut by the cutting blade 801 rotating and descending. After the cutting is completed, the cutting blade 801 should be returned to the initial height and stopped rotating, and the cut decorative line segment is removed, and then the line pressing assembly 1 is allowed to release the decorative line, and then the decorative line is moved to the outer end to abut against the surface of the limit baffle 508 and the cutting operation is repeated, so as to repeat the cutting operation. The line cutting assembly 8 is cut and processed into a plurality of decorative line segments of equal length in a cutting manner. Specifically, in the combination and disassembly operation of the line cutting assembly 8 and the operating table body 2, when the line cutting assembly 8 is assembled on the top of the operating table body 2, the line cutting assembly 8 can be detachably fixed to the top position of the operating table body 2 by means of the vertical sliding cooperation between the matching seat 905 and the matching groove 902 and the longitudinal sliding cooperation between the limiting rod 907 and the limiting hole 908. The fixing combination method of the line cutting assembly 8 on the top of the upper operating table body 2 is simple and easy to operate, which makes it easy to remove the line cutting assembly. 8 is quickly fixed on the top of the operating table body 2 for use. When the line cutting assembly 8 is disassembled on the top of the operating table body 2, it is only necessary to hold the pull handle 903 and pull it outward to make the limit rod 907 disengage from the limit hole 908 by stretching the spring 904, and then the matching seat 905 can be vertically disengaged from the matching groove 902 to disassemble the line cutting assembly 8 from the top of the operating table body 2. The disassembly method of the line cutting assembly 8 on the top of the operating table body 2 is simple and easy to operate, and then it is convenient to quickly disassemble the line cutting assembly 8 from the top of the operating table body 2 for regular inspection and maintenance.
