[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] This embodiment provides a manual mechanical clutch, such as Figure 1-3 As shown, the manual mechanical clutch comprises a bearing seat 1, an output shaft 4 rotatably arranged in the bearing seat 1, a flange 3 fixedly arranged at one end of the bearing seat 1, and an input shaft 2 rotatably arranged inside the flange 3; wherein the output shaft 4 is coaxially arranged with the input shaft 2; the clutch further comprises an internal gear sleeve 5 axially moving on the input shaft 2 for combining with the output shaft 4, and a driving mechanism 6 arranged on the bearing seat 1 for driving the internal gear sleeve 5 to move;

[0033] The driving mechanism 6 includes a connecting ring 61 which moves axially inside the bearing seat 1 and is rotatably connected to the internal gear sleeve 5, a connecting rod 62 which is fixedly mounted on the connecting ring 61 and passes through the bearing seat 1, a handle 63 which is sleeved on the end of the connecting rod 62 away from the connecting ring 61 and is used to contact the outer wall of the bearing seat 1, and a spring 64 which is arranged inside the handle 63, wherein the two ends of the spring 64 are respectively connected to the handle 63 and the connecting rod 62 for moving the handle 63 closer to the bearing seat 1; wherein a guide groove 11 for moving the connecting rod 62 is provided on the outer wall of the bearing seat 1.

[0034] Specifically, the input shaft 2 is connected to the flange 3 by screws and the second bearing 8, and only rotates but does not move axially. When the handle 63 is pushed from the right end position to the left end position, the inner gear sleeve 5 moves axially and engages with the outer teeth on the outer gear sleeve 7 of the output shaft 4, and the input shaft 2 transmits torque. The flange 3 is fixedly connected to the bearing seat 1 by screws. At the same time, the second bearing 8 is connected to the output shaft 4. A countersunk hole is provided on the outer circle of the bearing seat 1. When the handle 63 is not moving, it is fixed in the outer circle countersunk hole by a spring 64. A guide groove 11 is provided on the outer circle of the bearing seat 1. When the handle 63 is lifted, it can be pushed in the guide groove 11.

[0035] The input shaft 2 corresponding to the inside of the flange 3 and the output shaft 4 corresponding to the inside of the bearing seat 1 are both connected through the second bearing 8 .

[0036] An external gear sleeve 7 for meshing with the internal gear sleeve 5 is disposed on the outer wall of the input shaft 2 and the output shaft 4 .

[0037] A protrusion is installed at one end of the handle 63 close to the bearing seat 1, and countersunk holes matching the protrusion are provided at the two end positions of the bearing seat 1 corresponding to the guide groove 11.

[0038] More specifically, the handle 63 is connected to the inner gear sleeve 5 by screws and springs 64. When the handle 63 is stationary, it is fixed in the outer cylindrical countersunk hole of the bearing seat 1 by the tension of the spring 64. When the handle 63 is lifted, it comes out of the countersunk hole and can be pushed from the rightmost end to the left end in the guide groove 11 of the bearing seat 1, driving the inner gear sleeve 5 to move axially from right to left, thereby realizing the separation and combination of the input shaft 2 and the output shaft 4.

[0039] A third bearing 66 is disposed inside the connecting ring 61 , and the inner portion of the third bearing 66 is sleeved with the inner gear sleeve 5 .

[0040] A dust cover 65 is fixedly disposed inside the bearing seat 1, and the dust cover 65 is provided with a hole groove for inserting the connecting rod 62;

[0041] It is worth mentioning that the dust cover 65 has a hole groove for the connecting rod 62 to be inserted and fixed. The dust cover 65 is made of elastic rubber material. When stretched, it is in a straight shape corresponding to the guide groove 11, which is convenient for the handle 63 to pass through and move, and covers the guide groove 11 by stretching. Its function is to prevent dust from entering the guide groove 11 of the bearing seat 1 when the handle 63 moves.

[0042] Preferably, a first bearing 21 is sleeved on one end of the input shaft 2 close to the bearing seat 1 .

[0043] When in use, when the handle 63 of the manual mechanical clutch is lifted, it comes out of the countersunk hole, slides in the guide groove 11 of the bearing seat 1, and is pushed from one end of the guide groove 11 to the other end, driving the internal gear sleeve 5 to move axially from right to left. When the handle 63 is located at the rightmost end of the guide groove 11, it is fixed in the outer circle countersunk hole of the bearing seat 1 by the spring 64 inside the handle 63, so that the input shaft 2 and the output shaft 4 are combined to realize torque transmission. This form of manual mechanical clutch can work when the power, gas and oil are cut off, can be applied to a variety of occasions, and has a wider range of uses.

[0044] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
