[0039] Referring to Figure 1 and Figure 2 In the above embodiment, the bottom of the lower support 1 is fixed with the base 6, the both sides of the base 6 are connected with the rib plate 8, the both sides of the bottom of the base 6 are provided with the installation hole 7, the worker places the base 6 on the workbench, then the worker passes the bolt through the installation hole 7 and tightens, thereby completing the fixation of the base 6, the lower support 1 is stably placed, at the same time, the structure strength of the base 6 is increased through the rib plate 8, the base 6 is avoided to be bent and deformed.
[0040] Example 2:
[0041] Based on the above embodiment one, in order to further increase the structural strength, the following settings are now adopted.
[0042] See Figure 1 and Figure 2 In the above embodiments, multiple anti-loss ropes 4 are provided, and the multiple anti-loss ropes 4 are equally distributed. By increasing the number of anti-loss ropes 4, the structural strength is further improved, the service life is longer, and the magnet can be effectively prevented from being lost.
[0043] Example 3:
[0044] Based on the above embodiment 1, in order to prevent the power cord 5 from being torn off or pulled out, the following settings are now implemented.
[0045] See Figure 1 and Figure 2 In the above embodiment, the length of the power cord 5 is greater than the length of the anti-loss rope 4. Since the length of the anti-loss rope 4 is less than the length of the power cord 5, the anti-loss rope 4 bears the pulling force, thus preventing the power cord 5 from being pulled and damaged or falling off when it is moved onto the support 2.
[0046] The implementation principle of this utility model is as follows: First, the worker places the base 6 on the workbench, then the worker passes the bolt through the mounting hole 7 and tightens it, thereby fixing the base 6 and placing the lower bracket 1 stably. At the same time, the rib plate 8 increases the structural strength of the base 6 and prevents the base 6 from bending and deforming. It should be noted that if the size of the unmanned vehicle shell plate is large, several of these clamps can be placed on the workbench to achieve a better clamping effect through multi-point clamping. In addition, for the sake of easy display of the structure, the length of the anti-loss rope 4 and the power cord 5 appears to be short. In actual application, the length of the anti-loss rope 4 and the power cord 5 should be longer so that they can be wrapped around the side of the plate to facilitate placing the upper bracket 2 on the top of the unmanned vehicle shell plate.
[0047] When clamping is needed, the worker places the unmanned vehicle shell plate on the top of the lower support 1, and then the worker places the upper support 2 on the top of the unmanned vehicle shell plate; during this period, the setting of the anti-loss rope 4 avoids the loss of the upper support 2 and the first magnetic block 9, the second magnetic block 10, the first magnetic strip 11 and the second magnetic strip 12 inside the upper support 2, thereby improving safety, and the anti-loss rope 4 is a steel wire rope, which has high material strength and is resistant to pulling, and the number of anti-loss ropes 4 is increased to further improve the structural strength and have a long service life, which can effectively prevent the loss of magnets, and because the length of the anti-loss rope 4 is less than the length of the power cord 5, the anti-loss rope 4 bears the pulling force, avoiding the phenomenon that the power cord 5 is damaged or falls off when carrying the upper support 2; finally, the worker turns on all the first magnetic block 9, the second magnetic block 10, the first magnetic strip 11 and the second magnetic strip 12 inside the upper support 2 and the lower support 1, and the first magnetic block 9, the second magnetic block 10, the first magnetic strip 11 and the second magnetic strip 12 generate magnetic attraction force after being started, at this time the lower support 1 and the upper support 2 always approach each other to clamp the unmanned vehicle shell plate; at the same time, the setting of the protective pad 3 can avoid wear between the first magnetic block 9, the second magnetic block 10, the first magnetic strip 11 and the second magnetic strip 12 and the unmanned vehicle shell plate, which can cause damage to the magnets, and can increase the friction coefficient between the magnets and the unmanned vehicle shell plate, further avoiding the displacement of the unmanned vehicle shell plate during processing;
[0048] Because the magnetic poles of the first magnetic block 9 and the second magnetic block 10 are opposite, and because the second magnetic block 10 is wrapped around the periphery of the first magnetic block 9, when the upper support 2 is forced to horizontally displace, the first magnetic block 9 in the lower support 1 will generate a repulsive force on the second magnetic block 10 in the upper support 2 due to the same repulsion, and the second magnetic block 10 in the lower support 1 will generate a repulsive force on the first magnetic block 9 in the upper support 2, thereby avoiding the horizontal displacement of the upper support 2 causing the unmanned vehicle shell plate to loosen and displace;
[0049] Because the magnetic poles of the first magnetic strip 11 and the second magnetic strip 12 are opposite, and because the first magnetic strip 11 and the second magnetic strip 12 are staggered, when the upper support 2 is forced to rotate on the horizontal plane, the first magnetic strip 11 in the lower support 1 will generate a repulsive force on the second magnetic strip 12 in the upper support 2 due to the same repulsion, and the second magnetic strip 12 in the lower support 1 will generate a repulsive force on the first magnetic strip 11 in the upper support 2, thereby avoiding the rotation of the upper support 2 on the horizontal plane causing the unmanned vehicle shell plate to rotate.
[0050] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, the person skilled in the art can make the modification, replacement and change of no creative contribution to the embodiment according to the need after reading the specification without departing from the principle and the purpose of the utility model, but as long as in the patent right claim range of the utility model, it is protected by the patent law.
