[0033] Further, the dual power supply assembly 102 comprises a main power supply 102a and an auxiliary power supply 102b arranged in the outer clamping seat 101b, a first power supply line 102c connected with the main power supply 102a and arranged in the first incoming line pipe 101c, and a second power supply line 102d connected with the auxiliary power supply 102b and arranged in the second incoming line pipe 101d.

[0034] Further, the adjustment switching assembly 103 comprises a work-type support frame 103a connected with the shell assembly 101, a first rotating shaft seat 103b arranged on one side of the work-type support frame 103a, a second rotating shaft seat 103c arranged above the first rotating shaft seat 103b, a third rotating shaft seat 103d arranged on one side of the first rotating shaft seat 103b, a driving motor 103e connected with the first rotating shaft seat 103b, a rotating plate 103f connected with the tail end of the driving motor 103e, a sliding column 103g arranged at one end of the rotating plate 103f, a first rotating shaft 103h movably connected with the second rotating shaft seat 103c, a swing plate 103i connected with the first rotating shaft 103h, a sliding groove 103j arranged in the middle of the swing plate 103i and matched with the sliding column 103g, a broken gear 103k connected with the tail end of the first rotating shaft 103h, a second rotating shaft 103l connected with the third rotating shaft seat 103d, a gear 103m arranged at one end of the second rotating shaft 103l and meshed with the broken gear 103k, a switching plate 103n arranged on the second rotating shaft 103l, a conductive plate 103o arranged at the tail end of the switching plate 103n, a deformation push plate 103p arranged on one side of the switching plate 103n, and an arc-shaped double-head top plate 103q arranged at one end of the second rotating shaft 103l.

[0035] Further, the one-way clamping assembly 104 comprises a base plate 104a connected with the inner wall of the shell assembly 101, an arc-shaped elastic deformation sheet 104b arranged in the middle of the base plate 104a, a tightening shaft 104c arranged at the top end of the arc-shaped elastic deformation sheet 104b, a friction check head 104d arranged at the tail end of the tightening shaft 104c, four groups of trigger top heads 104e symmetrically arranged on both sides of the base plate 104a, a first spring 104f connected with one side of the trigger top head 104e, two groups of first straight-line moving grooves 104g arranged in the middle of the base plate 104a, a trigger platform 104h connected with the four groups of trigger top heads 104e, and a trigger vertical plate 104i arranged in the middle of the trigger platform 104h.

[0036] The tightening shaft 104c and the friction check head 104d are arranged on the inner and outer sides of the top end of the arc-shaped elastic deformation sheet 104b, and are arranged in two groups.

[0037] The trigger head 104e is provided with a moving block at the bottom, which is engaged with the first linear moving slot 104g.

[0038] Preferably, the first incoming line pipe 101c and the second incoming line pipe 101d are provided with an adaptive opening at the inside, which is plugged with the top-tight shaft 104c and the friction check head 104d, and the diameter of the adaptive opening is adapted to the diameter of the top-tight shaft 104c.

[0039] Further, the bidirectional clamping assembly 105 comprises a first push plate 105a, a second spring 105b connected with the first push plate 105a, and a second push plate 105c connected with the second spring 105b; the shell assembly 101 is provided with a second linear moving slot 101f, and the bottom of the first push plate 105a is provided with a moving block engaged with the second linear moving slot 101f.

[0040] Preferably, the second linear moving slot 101f and the moving block at the bottom of the first push plate 105a are engaged, and the moving block at the bottom of the trigger head 104e is engaged with the first linear moving slot 104g, so that the moving routes of the first push plate 105a and the trigger head 104e are limited and can only move in a linear direction, which ensures the correct cooperation between the components and the stability.

[0041] Further, the outer line assembly 106 comprises a power-on plate 106a provided at the outer side of the end of the first incoming line pipe 101c and the second incoming line pipe 101d, and an external wire 106b connected with the power-on plate 106a; the power-on plate 106a is provided with a gap between the first incoming line pipe 101c and the second incoming line pipe 101d, and the width of the gap is the same as the width of the conductive plate 103o.

[0042] It should be noted that the bidirectional clamping assembly 105 is always in contact with the arc-shaped double-head top plate 103q, and the clamping degree of the bidirectional clamping assembly 105 and the dual power assembly 102 can be adjusted in real time through the rotation of the arc-shaped double-head top plate 103q, which is convenient for disassembly and installation. The arc-shaped elastic deformation sheet 104b is made of elastic material and always maintains an arc shape, and changes the direction of the arc-shaped top end under the action of external force. The friction check head 104d is made of friction material and is inserted into the incoming line pipe through the top-tight shaft 104c, so that the friction check head 104d can be in contact with the power supply line and be fixed by extrusion, and the friction check head 104d is in full contact with the power supply line, which improves the friction between them and avoids the disconnection of the power supply line during use, thereby achieving the check function. The conductive plate 103o, the power-on plate 106a, and the power connection disc 101e are all made of conductive material.

[0043] In use, the outer wire 106b of the outer line assembly 106 extends out of the housing assembly 101 for connecting the working equipment for power supply. The device main body 100 is shown in the figure, at this time, the main power supply 102a is connected with the power connection disc 101e of the first incoming line pipe 101c through the first power supply line 102c, and the outer wire 106b can supply power to the working equipment through the conductive plate 103o, the power connection plate 106a and the power connection disc 101e. At this time, as shown in the figure, the one-way clamping assembly 104 makes the top pressing shaft 104c and the friction check head 104d enter the first incoming line pipe 101c to press and fix the first power supply line 102c and prevent it from falling off, ensuring the stability of the line during normal power supply. The bidirectional clamping assembly 105 adjusts the main power supply 102a and the auxiliary power supply 102b, ensuring the stability of the power supply.

[0044] Therefore, the device main body 100 is divided into three use processes, the first use process is the normal power supply process described above, the second use process is the power supply switching and recharging process, and the third use process is the recycling and utilization process. The use process of the device main body 100 is the recycling of the three processes, which can be gradually realized and recycled by controlling the driving motor 103e to rotate in one direction in the three processes, which is simple and convenient to operate.

[0045] In the second use process and the third use process, the adjustment switching assembly 103 can make the second shaft rotate back and forth for a certain angle. When the second shaft makes the conductive plate 103o at the bottom of the switching plate 103n contact with the end of the second incoming line pipe 101d, it is the second use process. On the basis of the above, when the second shaft makes the conductive plate 103o at the bottom of the switching plate 103n contact with the end of the first incoming line pipe 101c, it is the third use process.

[0046] In the second use process, the driving motor 103e is rotated by human or through a single-chip microcomputer, and the conductive plate 103o at the bottom of the switching plate 103n is connected with the end of the second incoming line pipe 101d. Figure 5 Figure 5 ​The view angle is used to control the driving motor 103e to rotate the rotating plate 103f clockwise, so that the sliding column 103g at one end of the rotating plate 103f moves in the sliding groove 103j in the middle of the swinging plate 103i, so that the swinging plate 103i can rotate clockwise by a certain angle, and thus the first rotating shaft 103h fixedly connected with the swinging plate 103i can also rotate the incomplete gear 103k connected therewith by a certain angle, so that the gear 103m controls the rotation of the second rotating shaft 103l, and the switching plate 103n, the deformed push plate 103p, and the arc-shaped double-head top plate 103q follow the rotation of the second rotating shaft 103l by a certain angle. The switching plate 103n makes the conductive plate 103o at the bottom thereof contact the end of the second incoming line pipe 101d from the end of the first incoming line pipe 101c, so that the second power supply line 102d of the auxiliary power supply 102b is in communication with the external wire 106b, and the power supply of the power supply is switched; the deformed push plate 103p contacts the trigger vertical plate 104i in the middle of the trigger platform 104h and pushes the trigger vertical plate 104i to move a certain distance in the process of rotation, so that the two groups of trigger heads 104e on one side of the deformed arc-shaped elastic sheet 104b extrude the deformed arc-shaped elastic sheet 104b, the deformed arc-shaped elastic sheet 104b will deform after being extruded a certain distance, and will pop up in the opposite direction of the original deformation direction, maintain the arc shape, and make the inside top tightening shaft 104c and the friction check head 104d extrude into the corresponding opening of the second incoming line pipe 101d, to fix and check the second power supply line 102d of the auxiliary power supply 102b; the maximum displacement distance of the trigger head 104e is when the deformed push plate 103p pushes the trigger vertical plate 104i to move to the maximum distance when they are about to be separated, and after they are separated, the trigger head 104e returns to the original position along a straight line under the action of the first spring 104f, the deformed arc-shaped elastic sheet 104b maintains elastic deformation, and the other two groups of trigger heads 104e are close to the deformed end of the deformed arc-shaped elastic sheet 104b, which is convenient for next switching. The arc-shaped double-head top plate 103q at the end of the second rotating shaft 103l first releases the fixing of the two groups of power supplies when rotating, so as to facilitate disassembly and extrusion of the two groups of bidirectional clamping assemblies 105 when rotating to the end to displace the two groups of power supplies and fix them again. At this time, the control driving motor 103e stops working, and through this process, the power supply of the external wire 106b by the main power supply 102a can be switched to the power supply of the external wire 106b by the auxiliary power supply 102b, and the fixing of the first power supply line 102c of the main power supply 102a is released, so as to facilitate the disassembly of the first power supply line 102c for maintenance or charging of the main power supply 102a, and facilitate the next switching. At any time when the power supply is working, the two groups of power supplies are clamped and fixed at the same time, so as to maintain the stability during work. The direction of this process is based on Figure 5 the view angle.

[0047] In the third process, the driving motor 103e continues to rotate in the original direction, and since the rotating plate 103f has been rotated to the farthest end in the second process, it will continue to rotate the swing plate 103i in the opposite angle, referring to the opposite process in the second process, so that the gear 103m rotates in the opposite order, and finally switches the power supply again, achieving the normal effect in the first process: the one-way clamping assembly 104 makes the top shaft 104c and the friction check head 104d enter the first wire inlet pipe 101c to fix the first power supply line 102c and prevent it from falling off, ensuring the stability of the line during normal power supply. The two-way clamping assembly 105 adjusted by the arc double-head top plate 103q clamps and fixes the main power supply 102a and the auxiliary power supply 102b, ensuring the stability of the power supply. The whole process only needs to start and stop the driving motor 103e, which is simple and convenient, and can quickly switch the power supply without additional operation to ensure the stability of the power supply during power supply, and is convenient for maintenance and repair of damaged power supply. The device main body 100 is small and integrated, easy to carry and transport.

[0048] In summary, by setting the adjusting and switching assembly, the power supply can be quickly switched, and when switching the power supply, the adjusting and switching assembly clamps and fixes the power supply line that will work through the one-way clamping assembly, ensures the stability of the power supply, and releases the fixation of the failed power supply line, which can be charged and recovered by disassembling the line, facilitating the recycling and switching of the use. When any power supply is working, the adjusting and switching assembly can stably clamp the dual power supply through the two-way clamping assembly, ensuring the stability of the whole.
