The bottom of the frequency converter body 1 is fixedly provided with two bottom plates 7, and two clamping grooves 8 are formed in one side of each of the two bottom plates 7. The clamping grooves 8 are used for cooperating with the clamping blocks 13 on the mounting plates 5, so as to realize quick mounting and dismounting of the frequency converter body 1. A plurality of air inlet holes 2 are formed in one side of the outer wall of the frequency converter body 1, and a heat dissipation fan is fixedly arranged on the inner wall of the frequency converter body 1 and located on one side of the air inlet hole 2. The heat dissipation fan is used for blowing the air introduced into the interior of the frequency converter body 1, so as to realize heat dissipation effect. A plurality of first air outlet holes 3 are formed in the other three sides of the outer wall of the frequency converter body 1. The first air outlet holes 3 are used for discharging the hot air in the interior of the frequency converter body 1, so as to form a heat dissipation channel.

[0032] A plurality of sliding grooves 12 are formed in one side of each of the mounting plates 5, and the clamping blocks 13 are slidably connected in the sliding grooves 12. The clamping blocks 13 cooperate with the clamping grooves 8, so as to realize fixed connection of the mounting plates 5 and the frequency converter body 1. The clamping blocks 13 and the sliding grooves 12 are fixedly provided with elastic sheets 14 made of elastic materials such as stainless steel or spring steel. The elastic sheets 14 are used for providing elastic force when the clamping blocks 13 slide into the clamping grooves 8, so as to ensure stability of the connection.

[0033] An adjusting mechanism is arranged on the surface of the mounting plate 5 and used for adjusting the clamping block 13. The adjusting mechanism comprises an adjusting groove 15 and a strip-shaped groove 16.
