The removal and removal function, and the arc-shaped clamping plate 2 can slide left and right along the slide groove. The clamping spacing between the convex limiting plate 104 and the convex limiting plate 104 is adjusted, which is suitable for clamping and limiting the circuit breakers 4 of different widths of two, three and four phases, and is widely used; two groups of positioning short shafts 105 are symmetrically welded backward at the upper and lower ends of the convex limiting plate 104, and two L-shaped top plates 3 are symmetrically slidably mounted on the two groups of positioning short shafts 105, and the two L-shaped top plates 3 are slidably fitted with the upper and lower end surfaces of the circuit breaker 4; two vertical connecting plates are symmetrically welded at the rear ends of the two groups of positioning short shafts 105, and the tail ends of the two vertical connecting plates are correspondingly welded and fixed together with the two L-shaped mounting strips 101; four L-shaped Insulating sleeve 301; four groups of positioning short shafts 105 are arranged at equal intervals between the two L-shaped mounting strips 101, and four mountain-shaped pushing frames 6 are installed on the bottom sections of the four groups of positioning short shafts 105 through spring pushing and sliding sleeves; four groups of horizontal support positioning shafts 107 are welded at equal intervals on the top of the bottom L-shaped mounting strip 101, and four sliding rods 5 are installed on the four groups of horizontal support positioning shafts 107 through spring pushing and sliding; a vertical square rod 503 is welded on each of the four sliding rods 5, and four limiting grooves are opened through the two L-shaped mounting strips 101 at equal intervals, and the upper and lower ends of the four vertical square rods 503 are correspondingly plugged into the eight upper and lower limiting grooves;The tail ends of the vertical support parts of the two L-shaped top plates 3 are welded with a protruding support rod, and the head ends of the two protruding support rods are rotatably connected with a pull rod 302. The tail ends of the two pull rods 302 are rotatably connected with the upper and lower protruding sections of the vertical square rod 503. The two pull rods 302, the two L-shaped top plates 3 and the vertical square rod 503 are connected together to form a double crank slider mechanism. Through this mechanism, the left and right sliding vertical square rod 503 can push and drive the two L-shaped top plates 3 to slide forward and backward, and the sliding rod 5 is pulled to the right to break. When the circuit breaker 4 is loosened and disassembled, the two L-shaped top plates 3 can be pushed forward to slide forward. When the upper and lower rows of wires of the circuit breaker 4 are not disassembled or are not completely separated from the circuit breaker 4, the two L-shaped top plates 3 will be blocked from moving forward and the plug plate 402 will be prevented from sliding down and being pulled out. This prevents the circuit breaker 4 from being removed from the card plate 1 when the wires on the circuit breaker 4 are forgotten to be removed, causing tearing damage to the wires. It can also prevent the circuit breaker 4 from being removed without power outage and without removing the wires, causing short circuit injuries. The safety of taking out; four threaded rods 103 are screwed and installed at equal intervals between the upper and lower L-shaped mounting strips 101, and the four threaded rods 103 are located in the middle of the four sets of vertical positioning shafts 106, and the four threaded rods 103 are screwed and matched with the middle protruding parts of the four convex sliding rods 202; the tail ends of the four sliding rods 5 are welded with a wedge block 502, and the head ends of the four sliding rods 5 are welded with a vertical supporting driving bar frame 501; the three vertical plugs on the mountain-shaped top push frame 6 pass through the L-shaped mounting strips at the bottom The mounting strip 101 abuts against the plug plate 402, and the mountain-shaped push frame 6 can push downward to pull out the plug plate 402, loosen the circuit breaker 4, and complete the removal of the circuit breaker 4 from the card plate 1; four trapezoidal force blocks 601 are welded on the middle part of the cross-bracing connecting plate at the top of the four mountain-shaped push frame 6, and the four wedge-shaped blocks 502 correspondingly abut against the inclined surfaces of the four trapezoidal force blocks 601. Through the guiding principle of the inclined surfaces of the wedge-shaped blocks 502 and the trapezoidal force blocks 601, the sliding rod 5 can be pulled rightward to push and drive the mountain-shaped push frame 6 to slide downward. ;

[0032] like Figure 4 As shown, a connecting rod 201 is rotatably connected to the slider at the middle position of the back of the four arc-shaped splints 2, and a convex sliding rod 202 is rotatably connected to the tail end of the four connecting rods 201. The four convex sliding rods 202 correspond to the four groups of vertical positioning shafts 106 for sliding cooperation. The convex sliding rod 202, the connecting rod 201 and the arc-shaped splint 2 are connected together to form a crank slider mechanism. Through this mechanism, the forward and reverse rotation of the threaded rod 103 can push and drive the convex sliding rod 202 to slide up and down, thereby controlling the left and right sliding adjustment of the arc-shaped splint 2.

[0033] like Figure 4As shown in the figure, four Z-shaped rockers 102 are rotatably installed through the card board 1 at equal intervals. At the first ends of the rotating shafts of the four Z-shaped rockers 102, a knob is sleeved, and the dial shafts at the second ends of the four Z-shaped rockers 102 are correspondingly inserted and matched with the four driving bar frames 501. Through the dial shaft, when the Z-shaped rocker 102 is screwed to the right, it can push and drive the sliding rod 5 to slide to the right, providing a driving force for the sliding and detachment of the insertion plate 402. Therefore, in the present invention, only by simply swinging the Z-shaped rocker 102 to the right through the knob can the detachment of the plugging positioning part of the circuit breaker 4 be completed, which saves the trouble of manually reaching into the cramped space at the bottom of the circuit breaker 4 inside the electrical box to detach the plugging positioning part, greatly reduces the disassembly difficulty of the circuit breaker 4, and is convenient and fast to operate and use.

[0034] As Figure 5 shown, the L-shaped top plate 3 and the U-shaped insulating sleeve 301 are both made of plastic. The U-shaped insulating sleeve 301 is correspondingly sleeved and matched with the peeled parts of the first ends of the wires in the upper and lower rows of wiring holes of the circuit breaker 4. The four U-shaped insulating sleeves 301 can sleeve and cover the peeled parts of the first ends of the wires, greatly reducing the situation of short circuit caused by arc connection during the use of the wires. And when the wiring of the upper and lower rows of wires of the circuit breaker 4 is completed, the horizontal parts of the two L-shaped top plates 3 are in contact with the upper and lower rows of incoming and outgoing wires.

[0035] Working principle: During use, the insertion plate 402 can plug and fix the circuit breaker 4 on the card board 1, and the arc-shaped clamping plate 2 and the convex-shaped limiting plate 104 can limit the installation position of the circuit breaker 4, so that the insertion plate 402 thereon can be within the pushing range of the mountain-shaped pushing frame 6, avoiding the dislocation of the mountain-shaped pushing frame 6 and the insertion plate 402 due to the unsuitable installation position of the circuit breaker 4 and unable to normally perform the function of taking and unloading the circuit breaker 4. And the arc-shaped clamping plate 2 can slide left and right along the sliding groove to adjust the clamping distance between it and the convex-shaped limiting plate 104, which is suitable for clamping and limiting circuit breakers 4 with different widths of two, three and four phases. Since the convex-shaped sliding rod 202, the connecting rod 201 and the arc-shaped clamping plate 2 are jointly connected to form a crank-slider mechanism, rotating the threaded rod 103 forward and backward can push and drive the convex-shaped sliding rod 202 to slide up and down, controlling the left and right sliding adjustment of the arc-shaped clamping plate 2;

[0036] When disassembling the circuit breaker 4, through the dial shaft, screwing the Z-shaped rocker 102 to the right can push and drive the sliding rod 5 to slide to the right. Through the guiding principle of the inclined surfaces of the wedge-shaped block 502 and the trapezoidal stress block 601, pulling the sliding rod 5 to the right can push and drive the mountain-shaped pushing frame 6 to slide down, and the mountain-shaped pushing frame 6 can push and detach the insertion plate 402 downward, releasing the circuit breaker 4 and completing the taking and unloading of the circuit breaker 4 on the card board 1;

[0037] The four L-shaped insulating sleeves 301 can be inserted to cover the stripped part of the head end of the wire, which greatly reduces the short circuit caused by arc connection during the use of the wire. After the connection of the upper and lower rows of wires of the circuit breaker 4 is completed, the horizontal parts of the two L-shaped top plates 3 are in contact with the upper and lower rows of in-and-out wires. The two pull rods 302, the two L-shaped top plates 3 and the vertical square rod 503 are connected together to form a double crank slider mechanism. Through this mechanism, the left and right sliding vertical square rod 503 can push and drive the two L-shaped top plates 3 to slide forward and backward, and When the right sliding rod 5 is used to loosen and disassemble the circuit breaker 4, it can be linked to push and drive the two L-shaped top plates 3 to slide forward. When the upper and lower rows of wires of the circuit breaker 4 are not disassembled or not completely separated from the circuit breaker 4, it will hinder the two L-shaped top plates 3 from moving forward and prevent the plug plate 402 from sliding down and being pulled out, so as to avoid the circuit breaker 4 being removed from the card plate 1 when the wires on the circuit breaker 4 are forgotten to be removed, causing tearing damage to the wires. It can also prevent the circuit breaker 4 from being removed without power outage and the wires being removed, causing short circuit and injury accidents.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
