However, in order to ensure the firmness of the rear end cover after installation, the prior art provides two sets of magnetic fixing clamp rings on the rear end cover. Therefore, during actual installation, it is necessary to manually pry open the two sets of magnetic fixing clamp rings one by one, which is cumbersome and time-consuming. Utility Model Content

However, in order to ensure the firmness of the rear end cover after installation, the prior art provides two groups of magnetic fixing clamp rings on the rear end cover. Therefore, during actual installation, it is necessary to manually pry open the two groups of magnetic fixing clamp rings one by one, which is cumbersome and time-consuming.

[0008] The movable joint comprises two connecting pieces symmetrically fixed on the outer wall of the rear end cover body, a power rod rotatably arranged between the two connecting pieces, and a movable seat which is U-shaped and tightly sleeved on the body of the power rod, and the movable seat is fixedly connected to the end of the connecting arm;

[0009] The synchronous action mechanism includes a movable bar laterally arranged above the rear end cover body, a transmission tooth plate fixedly connected to the end of the movable bar is vertically slidably arranged between the two connecting pieces, and a transmission assembly is arranged between the transmission tooth plate and the power rod.

[0010] Preferably, the transmission assembly includes a transmission rod rotatably arranged between the two connecting plates, a second gear meshing with the transmission gear plate is fastened and sleeved on the rod body of the transmission rod, and a first gear meshing with the second gear is fastened and sleeved on the rod body of the power rod located on the inner side of the movable seat.

[0011] Preferably, both ends of the movable bar are threaded with power screws, and the power screws are rotatably connected to the top surface of the rear end cover body.

[0012] Preferably, a knob block is fixed to the top end of the power screw, and anti-slip grooves are provided on the outer wall of the knob block.

[0013] Compared with the prior art, the advantage of the utility model lies in that: through the setting of the synchronous action mechanism, after the installation of the rear end cover main body on the motor is completed by using screws, it is only necessary to simply act on the movable bar in the synchronous action mechanism to slide down, and the transmission tooth plates at both ends of the movable bar will slide down between the corresponding two connecting plates along with the movable bar, so that the transmission tooth plate engages the second gear and rotates the transmission rod, so that the second gear synchronously engages the first gear, providing synchronous rotation force for the magnetic fixing rings and connecting arms in the two sets of magnetic fixing mechanisms, so that the two magnetic fixing rings are synchronously clamped to the motor housing.

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] Reference Figure 1-2 As shown, a firmly installed rear end cover of a motor comprises a rear end cover body 1 and a fixing plate 2 fixed on the outer wall of the rear end cover body 1, and a bolt reserved hole is opened on the fixing plate 2;

[0020] By setting the fixing plate 2, when assembling the rear end cover body 1 and the motor, the bolt reserved holes on the fixing plate 2 are pre-aligned with the matching fixing holes on the motor, and then the rear end cover body 1 can be effectively fixedly connected to the motor by only threading the bolts through the bolt reserved holes.

[0021] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that two sets of magnetic fixing mechanisms are symmetrically arranged on the rear end cover body 1;

[0022] The magnetic fixing mechanism comprises a magnetic fixing ring 3 rotatably arranged under the rear end cover body 1 in a semi-circular shape and a connecting arm 4 obliquely fixed to the end surface of the magnetic fixing ring 3, and a movable joint is arranged at the end of the connecting arm 4;

[0023] The movable joint comprises two connecting pieces 5 symmetrically fixed on the outer wall of the rear end cover body 1, a power rod 6 rotatably arranged between the two connecting pieces 5, and a movable seat 7 which is U-shaped and fastened to the rod body of the power rod 6, and the movable seat 7 is fixedly connected to the end of the connecting arm 4;

[0024] After the assembly of the end cover body 1 on the motor is completed by bolts, the connecting arm 4 is then opened to clamp the magnetic fixing ring 3 on the outer shell surface of the motor, and then the magnetic properties of the connecting arm 4 are used to make it adsorb on the outer shell surface of the motor, so that the connection between the rear end cover body 1 and the motor is more firm and stable, which effectively avoids the problem that when the existing rear end cover body 1 is installed on the motor, the motor and the rear end cover body 1 are usually connected to each other by a fixing structure fixed by bolts, and the bolt fixing is relatively simple, so the fixing of the rear end cover body 1 on the motor is not very stable and firm;

[0025] Further, refer to Figure 1 and Figure 2As shown, it is worth noting that a synchronization mechanism is provided between the two sets of magnetic fixing mechanisms;

[0026] The synchronous action mechanism includes a movable bar 11 disposed transversely above the rear end cover body 1, a transmission tooth plate 12 fixedly connected to the end of the movable bar 11 is vertically slidably disposed between the two connecting pieces 5, and a transmission assembly is disposed between the transmission tooth plate 12 and the power rod 6;

[0027] The transmission assembly includes a transmission rod 8 rotatably disposed between two connecting plates 5, a second gear 10 meshing with a transmission toothed plate 12 is fastened and sleeved on the rod body of the transmission rod 8, and a first gear 9 meshing with the second gear 10 is fastened and sleeved on the rod body of the power rod 6 located inside the movable seat 7;

[0028] Through the setting of the synchronous mechanism, as shown above, after the installation of the rear end cover body 1 on the motor is completed by screws, it is only necessary to simply slide the movable bar 11 in the synchronous mechanism, and the transmission tooth plates 12 at both ends of the movable bar 11 will slide down between the corresponding two connecting plates 5 along with the movable bar 11, so that the transmission tooth plate 12 engages the second gear 10 and rotates the transmission rod 8, so that the second gear 10 synchronously engages the first gear 9, providing synchronous rotation force for the magnetic fixing rings 3 and the connecting arms 4 in the two sets of magnetic fixing mechanisms, so that the two magnetic fixing rings 3 are synchronously clamped to the motor housing, compared with the prior art operation method of manually prying the magnetic fixing rings 3 one by one, this effectively improves the manual operation efficiency and enhances practicality.

[0029] Further, refer to Figure 2 As shown, it is worth noting that both ends of the movable bar 11 are threaded with a power screw 13, and the power screw 13 is rotatably connected to the top surface of the rear end cover body 1;

[0030] By setting the power screw 13 , the power screw 13 is rotated, and the movable bar 11 can slide down along the shaft of the power screw 13 by the thread structure during the rotation of the power screw 13 , and then act on the transmission tooth plate 12 to slide down between the two connecting pieces 5 .

[0031] Further, refer to Figure 2 As shown, it is worth noting that a knob block is fixed to the top of the power screw 13, and anti-slip grooves are provided on the outer wall of the knob block;

[0032] By setting the knob block, twisting the knob block can effectively provide rotational force for the power screw 13, and during the rotation process, the anti-slip grooves on the outer wall of the knob block can effectively increase the friction between the person's hand and the outer wall of the knob block to avoid slipping.
