The mounting 2 is installed on the fixed column 3, because the difference of mounting panel 7, so need highly adjust the fixed column 2, thereby the accessible rotates the fixed column 3 and adjusts the height of fixed column 3 in fixed orifices 111, and fixed column 3 drives the mounting 2 and removes to the height position of adjustable mounting 2, the mounting panel 7 of adaptable different thickness. On the other hand, when the fixing piece 2 is not needed to fix, the fixing column 3 can be detached from the mounting plate 7, and the motor body 1 can still be fixed by using the bolts 8, so that the motor fixing modes are more diversified.

Referring to fig. 3, a limiting convex ring 31 is coaxially disposed at one end of the fixing column 3, which is close to the motor body 1, and the diameter of the limiting convex ring 31 is larger than that of the fixing column 3. When the fixed column 3 is rotated, the fixed column 3 can move along the axial direction of the fixed hole 111, and when the fixed column 3 moves to a certain height, the limiting convex ring 31 abuts against the fixed plate 11 to limit the axial sliding of the fixed column 3, so that the fixed column 3 is prevented from sliding out of the fixed hole 111. In this embodiment, the fixing post 3 and the limiting convex ring 31 are integrally formed, which facilitates the processing and production of the fixing post 3 and the limiting convex ring 31.

The one end that spacing bulge loop 31 was kept away from to fixed column 3 is provided with inclined plane 32, and the diameter of fixed column 3 inserted the end can be reduced to inclined plane 32 for fixed column 3 more conveniently inserts in the mounting hole 71 and fixes, has made things convenient for the installation of motor body 1.

Referring to fig. 4, the fixing member 2 includes a fixing block 41 and a spring 42. The outer side wall of the fixed column 3 is vertically provided with a sliding groove 33, and the fixed block 41 is glidingly inserted in the sliding groove 33.

The spring 42 presses the fixing block 41 partially out of the notch of the sliding groove 33. When the fixed column 3 is inserted into the mounting hole 71 of the mounting plate 7, the fixed block 41 is located on one side, far away from the motor body 1, of the mounting plate 7, the spring 42 presses the fixed block 41 partially out of the notch of the sliding groove 33, and the fixed block 41 slides out to partially abut against the mounting plate 7, so that the axial sliding of the fixed column 3 is limited, and the motor body 1 is further fixed.

Preferably, in this embodiment, two sets of fixing members 2 are disposed on each fixing post 3, and a connecting line between the two sets of fixing members 2 passes through the axis of the fixing post 3. Through setting up two sets of mounting 2, two sets of mounting 2 are fixed motor body 1 simultaneously, make the fixed more stable of motor. And when one group of fixing pieces 2 is damaged, the other group of fixing pieces 2 can still fix the motor body 1, so that the risk that the motor body 1 cannot be fixed due to the damage of the fixing pieces 2 is reduced.

The side wall of the fixed block 41 far away from the spring 42 is provided with a guide surface 412, and the guide surface 412 is gradually reduced and inclined from one side close to the limiting convex ring 31 to one side far away from the limiting convex ring 31. Through setting up guide surface 412, when fixed column 3 inserts in mounting hole 71, fixed block 41 is by the pore wall butt of mounting hole 71, and fixed block 41 is spacing by the groove 33 that slides this moment for fixed block 41 can only retract into the inslot that slides 33, and when fixed block 41 retracted into the inslot that slides 33, fixed column 3 can continue to insert in mounting hole 71, does not need artificial impressing fixed block 41 into the inslot that slides 33, has made things convenient for the fixed of motor.

Referring to fig. 4, the motor further comprises an unlocking piece 5, the unlocking piece 5 comprises an extension rod 52 and a butterfly-shaped block 51, the extension rod 52 is arranged on the side wall of the fixed block 41, the fixed column 3 is vertically provided with a connecting groove 34 for the extension rod 52 to slide on the groove wall of the sliding groove 33, the axes of the connecting groove 34 and the fixed column 3 are arranged in parallel, the connecting groove 34 penetrates through one side, far away from the fixed column 3, of the limiting convex ring 31, when the extension rod 52 slides towards the groove bottom of the connecting groove 34, the extension rod 52 can synchronously drive the fixed block 41 to slide towards the sliding groove 33, so that the fixed block 41 slides into the sliding groove 33, the motor is convenient to detach, and when the spring 42 extrudes the fixed block 41 from the sliding groove 33, the extension rod 52 abuts against the groove wall of the connecting groove 34 to limit the fixed block 41, so that the fixed block 41 cannot completely deviate from the sliding groove 33, and the motor body 1 is convenient to fix.
