In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0023] Example 1

[0024] like Figure 1-4As shown, it is the first embodiment of the utility model, which provides a new release handle for the brake of the reduction motor, including a brake assembly 1, a release assembly 2 is arranged on the front of the brake assembly 1, and the release assembly 2 includes a handle assembly 21 and a positioning assembly 22. The handle assembly 21 is used to manually release the brake, and the handle assembly 21 includes a pull ring 211, a handle 212, a fixing seat 213, a connecting rod 214 and a second spring 215. The positioning assembly 22 is used to limit the handle assembly 21, and the positioning assembly 22 includes a first A toothed ring 221, a second toothed ring 222, a third spring 223 and a movable rod 224, the first toothed ring 221 is fixedly connected to one side of the pull ring 211, the second toothed ring 222 is meshed with the first toothed ring 221, one end of the movable rod 224 is fixedly connected to the second toothed ring 222, the other end of the movable rod 224 passes through the outside of the fixed seat 213, the third spring 223 is sleeved on the surface of the movable rod 224, and the two ends of the third spring 223 are respectively fixedly connected to the second toothed ring 222 and the inner wall of the fixed seat 213.

[0025] like Figure 1-4 As shown, the brake assembly 21 can be used to brake the reduction motor. When the brake assembly 1 is powered off, the reduction motor can be released from the brake by pulling the handle assembly 21. The moving position of the handle assembly 21 can be fixed by the positioning assembly 22. First, the movable rod 224 is pulled, and the movable rod 224 drives the second gear ring 222 to disengage from the pull ring 211. When the second gear ring 222 moves, it squeezes the third spring 223, causing the third spring 223 to deform under force. Then, the handle 212 is pulled, and the handle 212 drives the pull ring 211 to move upward along the inner cavity of the fixed seat 213. When the pull ring 211 moves, the movable disk 102 is driven to move through the connecting rod 214, thereby contacting the brake of the reduction motor. The second spring 215 is used to reset the pull ring 211. Then, the movable rod 224 is released, and the reset elastic force of the third spring 223 pushes the second gear ring 222 to engage with the first gear ring 221, thereby fixing the position of the pull ring 211, thereby enabling the reduction motor to continue to maintain the brake release state.

[0026] Example 2

[0027] Reference Figure 1 , 4 5 is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0028] In this embodiment, the brake assembly 1 includes an end cover 101, a movable disk 102, a pressure plate 103, a brake pad 104, a sleeve 105, a mounting hole 106 and a first spring 107. The mounting hole 106 is opened around the surface of the end cover 101, and the first spring 107 is installed in the inner cavity of the mounting hole 106. One end of the first spring 107 away from the inner cavity of the mounting hole 106 contacts the movable disk 102.

[0029] The pressure plate 103 is located on the front of the movable plate 102 , the brake pad 104 is located between the movable plate 102 and the pressure plate 103 , the pressure plate 103 is threadedly connected to the end cover 101 through bolts, and the shaft sleeve 105 is located in the inner cavity of the pressure plate 103 and meshed with the inner cavity of the pressure plate 103 .

[0030] like Figure 1 , 4 As shown in Figure 5, an electromagnetic coil is also installed in the inner cavity of the end cover 101. The magnetic force generated by the electromagnetic coil causes the movable disk 102, the pressure plate 103, the brake pad 104 and the shaft sleeve 105 to brake the output shaft of the reduction motor, thereby providing a braking effect for the reduction motor. The shaft sleeve 105 is sleeved on the surface of the output shaft of the reduction motor, and the end cover 101 is threadedly connected to the reduction motor housing through bolts.

[0031] Example 3

[0032] Reference Figure 1-3 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0033] In this embodiment, the fixing seat 213 is fixed to the surface of the pressure plate 103 , and both ends of the pull ring 211 are movably connected to the inner cavity of the fixing seat 213 through movable pins.

[0034] One end of the handle 212 is fixedly connected to the pull ring 211 , one end of the connecting rod 214 is fixedly connected to the movable disk 102 , and the other end of the connecting rod 214 passes through the front side of the pressure plate 103 and is fixedly connected to the pull ring 211 .

[0035] The second spring 215 is sleeved on the surface of the connecting rod 214 , and two ends of the second spring 215 are fixedly connected to the pressure plate 103 and the pull ring 211 respectively.

[0036] like Figure 1-3 As shown, by pulling the handle 212, the handle 212 drives the pull ring 211 to move upward along the inner cavity of the fixing seat 213. When the pull ring 211 moves, it drives the movable disk 102 to move through the connecting rod 214, so as to contact the brake of the reduction motor.

[0037] When in use, first pull the movable rod 224, which drives the second gear ring 222 to disengage from the pull ring 211. When the second gear ring 222 moves, it squeezes the third spring 223, causing the third spring 223 to be deformed under force. Then pull the handle 212, which drives the pull ring 211 to move upward along the inner cavity of the fixed seat 213. When the pull ring 211 moves, it drives the movable disk 102 to move through the connecting rod 214, so that it can contact the brake of the reduction motor. The second spring 215 is used to reset the pull ring 211. Then release the movable rod 224, and the reset elastic force of the third spring 223 pushes the second gear ring 222 to engage with the first gear ring 221, so that the position of the pull ring 211 can be fixed, so that the reduction motor can continue to maintain the brake release state.
