[0021] In this embodiment: Further improvements are made to this existing main body in this application. For details, refer to the publicly disclosed technology below. To solve the technical problems existing in this prior art, as disclosed in the background art above, "the operating handle 1 of the circuit breaker trolley is designed to be relatively long. When performing the operation of pushing the circuit breaker in or out, the operating rod will change with the position of the circuit breaker trolley. If the operating handle 1 is accidentally separated from the trolley during the operation, it is very easy to cause the contacts inside the circuit breaker to discharge and damage the equipment." In combination with the use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, an auxiliary support assembly 2 is added to this application document.

[0022] Furthermore:

[0023] As Figures 1-4 shown:

[0024] An auxiliary support assembly 2 is provided on the handle 1. The auxiliary support assembly 2 includes a fixed sleeve 201 provided on the handle 1, a fixed seat 203 fixed on the surface of the fixed sleeve 201, and a plurality of groups of equidistantly arranged brackets 202 provided on the fixed seat 203. One end of the bracket 202 is provided with a suction cup 204. Threads are provided on the surface of the handle 1, and the handle 1 is threadedly connected in a thread groove formed inside the fixed sleeve 201 through the threads.

[0025] In this embodiment: When using the device for the operation of putting the auxiliary power switch trolley in and out, first hold the bracket 202 by hand and rotate the handle 1 so that the handle 1 extends a small part in front of the bracket 202 and the suction cup 204. At this time, bring the suction cup 204 on the bracket 202 into contact with the cabinet door of the switchgear and adsorb it on the surface of the cabinet door of the switchgear. At this time, the front end part of the handle 1 just inserts into the socket of the circuit breaker. Then rotate the handle 1. As the handle 1 is rotated, the driving mechanism of the circuit breaker (not shown in the figure) is driven to rotate at this time. During this process, through the auxiliary fixed support and limit of the bracket 202, the fixed sleeve 201 and the suction cup 204, the design defect during the operation of the old-fashioned switchgear can be effectively solved, the possibility of improper operation caused by external factors such as human factors resulting in the separation of the handle 1 from the trolley is avoided, the discharge of the contacts inside the circuit breaker and the damage of the equipment are avoided, and it is also beneficial for novice operation. After the device fixes the operating handle 1, the complex operation process can be simplified, the use effect of the device can be improved, and the actual use requirements can be met.

[0026] Even further;

[0027] In an alternative embodiment, the fixed sleeve 201 is threadedly connected with a movable sleeve 207 through a threaded groove formed on its outer surface. A connecting piece 208 is rotatably connected to the surface of the movable sleeve 207 through a bearing. One end of the bracket 202 is hinged to a movable connecting frame 210 through a hinge seat. The other end of the movable connecting frame 210 is hinged to the connecting piece 208 through a hinge seat. One end of the bracket 202 away from the suction cup 204 is hinged to a fixed seat 203 through a hinge seat. The bracket 202 is hinged to the suction cup 204 through a hinge shaft.

[0028] In this embodiment: After use, detach the suction cup 204 from the switch cabinet door. By rotating the movable sleeve 207, the connecting piece 208 is driven to move, and the movable connecting frame 210 is driven by the connecting piece 208 to fold at an angle. At the same time, the bracket 202 is driven to move in a circular motion around the hinge shaft on the fixed seat 203, folding multiple groups of brackets 202, which is convenient for storage, does not occupy a large amount of space, and further improves the use effect of the device.

[0029] Furthermore;

[0030] In an alternative embodiment, a hexagonal block 209 is fixed to the surface of the movable sleeve 207.

[0031] In this embodiment: When rotating the movable sleeve 207, use a tool to clamp on the hexagonal block 209, which is more convenient to rotate the movable sleeve 207.

[0032] Furthermore;

[0033] In an alternative embodiment, a sleeve 205 is sleeved on one end of the handle 1, and a rubber pad 206 is fixed to the surface of the sleeve 205.

[0034] In this embodiment: When rotating the handle 1, by holding the sleeve 205 by hand, the friction between the sleeve 205 and the handle 1 can be reduced. At the same time, the rubber pad 206 on the sleeve 205 can better improve the operation comfort and the use effect of the device.

[0035] Furthermore;

[0036] In an alternative embodiment, the end of the handle 1 away from the sleeve 205 is provided with a shape adapted to the breaker socket.

[0037] In this embodiment: The end of the handle 1 away from the sleeve 205 is provided with a shape adapted to the breaker socket, which can be better inserted into the breaker socket and improve the pushing effect on the power switch trolley.

[0038] Working principle and usage process of the present utility model: When using the device for assisting in the insertion and removal operation of the auxiliary power switch trolley, first hold the bracket 202 and rotate the handle 1 so that the handle 1 extends a small part to the front end of the bracket 202 and the suction cup 204. At this time, contact the suction cup 204 on the bracket 202 with the cabinet door of the switchgear and adsorb it on the surface of the cabinet door of the switchgear. At this time, the front end part of the handle 1 just inserts into the circuit breaker socket. Then rotate the handle 1. While rotating the handle 1, by holding the sleeve 205, the friction between the sleeve 205 and the handle 1 can be reduced. At the same time, the rubber pad 206 on the sleeve 205 can better improve the comfort of operation and enhance the usage effect of the device. As the handle 1 is rotated, the driving mechanism of the circuit breaker (not shown in the figure) is driven to rotate at this time. During this process, through the auxiliary fixed support and limit of the bracket 202, the fixed sleeve 201 and the suction cup 204, the design defect during the operation of the old-fashioned switchgear can be effectively solved, avoiding the possibility that the handle 1 is disengaged from the trolley due to improper operation caused by external factors such as human factors, and avoiding the damage of the equipment due to the discharge of the internal contacts of the circuit breaker. At the same time, it is beneficial for novice operation. After the operation handle 1 is fixed, the complex operation process can be simplified, the usage effect of the device can be improved, and the actual usage requirements can be met. When the use is completed, detach the suction cup 204 from the cabinet door of the switchgear. By rotating the movable sleeve 207, the connecting piece 208 is driven to move, and the movable connecting frame 210 is driven to fold at an angle through the connecting piece 208. At the same time, the bracket 202 is driven to make a circular motion around the hinge axis on the fixed seat 203, and multiple groups of brackets 202 are folded, so as to facilitate storage and not occupy a large amount of space, further improving the usage effect of the device.
