[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When installing the circuit breaker body, insert the mounting block on the top of the circuit breaker body into the second L-shaped block, push the circuit breaker body upward, and squeeze the telescopic rod and the spring at the same time. When the mounting block at the bottom of the circuit breaker body is completely located directly above the first L-shaped block, release the circuit breaker body. The circuit breaker body will move downward under the action of the telescopic rod and the spring, and the mounting block at the bottom of the circuit breaker body will be inserted into the first L-shaped block.

After the mounting block at the bottom is completely separated from the first L-shaped block, the circuit breaker body can be removed from the inside of the distribution cabinet, and the maintenance personnel can perform maintenance operations on it.

[0011] 2. Beneficial effect: When the maintenance personnel need to inspect the circuit breaker body inside the distribution cabinet, they push the circuit breaker body upwards, squeezing the telescopic rod and the spring at the same time. When the mounting block at the bottom of the circuit breaker body is completely separated from the first L-shaped block, the circuit breaker body can be removed from the inside of the distribution cabinet, and people can repair the circuit breaker body. After the maintenance is completed, the mounting block on the top of the circuit breaker body is inserted into the second L-shaped block, and the circuit breaker body is pushed upwards. When the mounting block at the bottom of the circuit breaker body is completely located directly above the first L-shaped block, the circuit breaker body is released and can move downward under the action of the telescopic rod and the spring, and the mounting block at the bottom is inserted into the first L-shaped block. This makes it easier to disassemble and assemble the circuit breaker body, thereby facilitating people to inspect the circuit breaker body.

[0012] Preferably, a fastening bolt passes through the second L-shaped block, and a threaded hole matching the fastening bolt is provided on the mounting block on the top of the circuit breaker body. When the two mounting blocks on the circuit breaker body are respectively inserted into the first L-shaped block and the second L-shaped block, the fastening bolt is tightened to be threadedly connected with the mounting block on the top of the circuit breaker body. This can better fix the circuit breaker body, thereby making the circuit breaker body inside the distribution cabinet more stable during operation.

[0013] Preferably, the number of telescopic rods is three, and the telescopic rods are equidistantly distributed in a linear array on the top of the second L-shaped block. By setting the number of telescopic rods on the top of the second L-shaped block to three, the outer walls of the three telescopic rods are all sleeved with springs, so that the telescopic rods can exert a greater thrust on the second L-shaped block, thereby achieving a better fixing effect on the circuit breaker body.

[0014] Preferably, a symmetrical T-shaped slider is fixedly connected to one side of the second L-shaped block, and a T-shaped groove matching the T-shaped slider is provided on the inner wall of the cavity. When the second L-shaped block slides inside the cavity, the T-shaped slider arranged on one side of the second L-shaped block and the T-shaped groove provided on the inner wall of the cavity can better limit and guide the second L-shaped block, thereby making the second L-shaped block more stable when sliding inside the cavity.

[0015] Preferably, the number of the fastening bolts is two, and the fastening bolts are symmetrically arranged on the second L-shaped block. By setting the number of the fastening bolts on the second L-shaped block to two, when the two mounting blocks on the circuit breaker body are respectively inserted into the first L-shaped block and the second L-shaped block, the two fastening bolts on the second L-shaped block are tightened, which can better fix the circuit breaker body, thereby further improving the stability of the circuit breaker body.

[0016] Preferably, a knob is fixedly connected to the end of the fastening bolt away from the mounting block, and the outer wall of the knob is provided with anti-slip grooves. The knob set at one end of the fastening bolt can make it easier and more labor-saving for people to turn the fastening bolt. The anti-slip grooves on the outer wall of the knob can increase the friction between people's hands and the knob, thereby effectively preventing people's hands from slipping when turning the knob.

[0017] Preferably, the inner walls of the first L-shaped block and the second L-shaped block are fixedly connected with rubber pads. Since the rubber material is relatively soft, the rubber pads arranged on the inner walls of the first L-shaped block and the second L-shaped block can effectively avoid hard contact between the mounting block on the circuit breaker body and the inner walls of the first L-shaped block and the second L-shaped block, thereby providing better protection for the circuit breaker body.
