DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. EMBODIMENT

[0025] As Figures 1-5 shown, the utility model provides an easily dismountable structure electric actuator, including electric actuator body 1, electric actuator body 1 includes the shell 2, the bottom end of shell 2 is fixedly installed with connecting plate 4, the below of connecting plate 4 is detachably installed with valve body 3, is provided with dismounting unit between shell 2 and valve body 3, the above of dismounting unit is provided with protection unit, and protection unit includes the limit sliding groove 431 of being opened in the inside of connecting branch plate 43, and the inside of limit sliding groove 431 is slidably installed with protective cover 432.

[0026] Further, by the protective cover 432 on the outer surface of connecting branch plate 43 is pushed down, is made its sleeve joint the outer surface of both connection, reaches the effect of protection. EMBODIMENT

[0027] As Figures 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the disassembly and assembly unit includes a through groove 41 formed around the connecting plate 4. A rotating rod 42 is fixedly installed on the inner walls of both sides of the through groove 41. A connecting support plate 43 is rotatably sleeved on the outer surface of the rotating rod 42. Positioning holes 44 are formed at both ends of the other end of the connecting support plate 43. A toggle block is fixedly installed on the outer side of the other end of the connecting support plate 43. A connecting block 45 is fixedly installed at the middle position of the bottom end of the connecting plate 4. A valve stem 31 is fixedly installed on the top of the valve body 3. An mounting ring plate 32 is fixedly sleeved on the outer surface of the bottom end of the valve stem 31. U-shaped mounting blocks 33 are fixedly installed on all four sides of the top of the 2. Through holes are opened on both sides of the U-shaped mounting blocks 33. Limiting rods 34 are fixedly installed on all four sides of the outer surface of the two sides of the U-shaped mounting blocks 33. A moving plate 35 is slidably sleeved on the outer surface of the limiting rod 34. A return spring 36 is movably sleeved on the outer surface of the limiting rod 34 outside the moving plate 35. A piston rod 37 is fixedly connected to the inner side of the moving plate 35. The other end of the piston rod 37 extends through the through hole to the inner walls of both sides of the U-shaped mounting blocks 33. An abutting ball 38 is fixedly installed on the other end of the piston rod 37. The abutting ball 38 is movably inserted into the inside of the positioning hole 44.

[0028] Furthermore, when the valve body 3 and the electric actuator body 1 are connected, the connecting support plates 43 on the periphery of the connecting plate 4 are pushed downwards so that their bottom ends abut against the inside of the U-shaped mounting block 33.
