As shown in fig. 8, in another embodiment, the handle further includes a bayonet 5, the bayonet 5 is clamped at an opening of the accommodating cavity 13 and limits the base 2 in the accommodating cavity 13, that is, the bayonet 5 is clamped with the handle 1, so that the handle 13 can only rotate relative to the base 2 while the axial movement of the base 2 relative to the accommodating cavity 13 is avoided, specifically, the bayonet 5 is arranged between the base 2 and the handle 1, that is, the outer diameter of the base 2 and the inner diameter of the accommodating cavity 13 of the handle 1, so that the connection between the base 2 and the handle 1 can bear a larger external force. Further, bayonet lock 5 passes through the bolt fastening with base 2, and then make bayonet lock 5 rotate for handle 1, bayonet lock 5 can effectively avoided bayonet lock 5 to take off and then cause base 2 and handle 1 to be connected the problem of inefficacy under the extreme condition after 2 are fixed with the base, the while has also avoided forming cutting or wearing and tearing at handle 1 for the position of the radial direction of bayonet lock trench on handle 1 of base pivoted in-process bayonet lock 5, and then reduce the structural strength of handle 1, reduce the joint strength of handle 1 and base 2 promptly. Further, a boss 22 protruding relative to the connecting surface of the base 2 is further arranged on the base 2, the boss 22 and the base 2 are fixed and integrally formed, and the boss 22 is polygonal; in the embodiment, the boss 22 is a quadrilateral, and further, the rotating shaft 35 in the embodiment of the rotating shaft penetrates through the boss 22; particularly, because base 2 is connected through the bolt with the frame of door and window or section bar, and handle 1 then can rotate for base 2, consequently base 2 can receive the influence of moment of torsion power with the junction of section bar, and then can make connecting bolt appear not hard up phenomenon easily along with long-term use, and set up behind boss 22, set up the through-hole of mutually supporting with boss 22 on the section bar promptly, for example quadrangle through-hole, make base 2 can share partly to the section bar with the moment of torsion power that receives, the problem that connecting bolt is easily not hard up has been reduced promptly, and simultaneously, the locate function of base also can be realized to polygonal boss 22, and then the installation of the handle of being convenient for, if the handle of being convenient for in the installation, the bolt hole on base 2 and the location of the via hole on the section bar.

As shown in fig. 9, in another embodiment, the handle further includes a bayonet 5, a connecting end of the shaft sleeve 37 far away from the planet carrier 33 extends out of the base 2, and a second external spline 80 and an annular groove 81 are further provided on a connecting end of the shaft sleeve 37 far away from the planet carrier 33, and the second external spline 80 and the annular groove 81 are sequentially arranged along an axis of the shaft sleeve 37 and toward the planet carrier 33; further, the bayonet 5 comprises a pin ring 51 and a lock ring 52, wherein the pin ring 51 is provided with a second internal spline 53 which is matched with the second external spline 80, the lock ring 52 is provided with at least one locking tongue 54 along the circumferential direction, one end of the locking tongue 54 is integrally formed with the lock ring 52, and the other end of the locking tongue 54 extends upwards away from the lock ring 52 along the axial direction of the lock ring 52; further, when the connection between the shaft sleeve 37 and the base 2 needs to be formed through the bayonet 5, the second internal spline 53 of the pin ring 51 passes through the second external spline 80 and is placed in the annular groove 81, the lock ring 52 is sleeved outside the second external spline 80 of the rotating shaft 37, and the lock tongue 54 is placed between the adjacent keys in the second internal spline 53 and the second external spline 80, that is, the lock tongue 54 and the pin ring 51 are clamped and fixed; further, since the latch tongue 54 is disposed between the adjacent keys and the adjacent keys in the second internal spline 53 and the second external spline 80, the pin ring 51 needs to rotate a certain angle relative to the second external spline 80 of the rotating shaft 37, in this embodiment, since the second external spline 80 has three keys in total and the distances between the keys are the same, the pin ring 51 needs to rotate 60 degrees relative to the rotating shaft 37, so that the keys of the second internal spline 53 and the second external spline 80 are on the same projection plane, and the latch tongue 54 is inserted from the empty position between the keys, so that the pin ring 51 and the lock ring 52 form a locking state, further, since the pin ring 51 needs to rotate a certain angle relative to the second external spline 80 of the rotating shaft 37, so that the keys of the second internal spline 53 and the second external spline 80 are on the same projection plane, in the axial direction relative to the rotating shaft 37, the pin ring 51 and the rotating shaft 37 can form an axial fixation, finally, the base 2 and the handle 1 are in rotating connection; the use of the locking pin 5 also avoids cutting or abrasion of the radial portion of the annular groove 81 on the shaft 37 caused by the rotation of the pin ring 51 during the rotation of the handle 1 relative to the base, thereby reducing the strength of the connection of the handle 1 relative to the base 2.

Further, in the axial direction relative to the accommodating cavity 13, the first end of the accommodating cavity 13 (handle) is connected with the rotating shaft 35, the base 2 is located at the second end of the accommodating cavity 13, meanwhile, the rotating shaft 35 penetrates through the base 2, and since the gear ring 31 is fixed with the base 2, when the handle is operated, in this case, besides the stress at the joint of the base 2 and the handle 1, the received force is dispersed to the handle 1 far away from the other end of the base 2 through the rotating shaft 35, that is, the stress in the axial direction of the connecting end 11 of the handle 1 is relatively balanced (both ends of the connecting end 11 participate in the stress, one end of the connecting end 11 is rotatably connected with the base 2, and the other end is connected with the free end); the stress point of traditional handle mainly concentrates on the junction (pivot position) of handle and base 2, and can not increase axle sleeve 37 length on the base again in order to reduce the power that receives (increase axle sleeve 37 length on the base then can increase external base's whole thickness or volume) for cost control and structural design requirement, and further, along with long-time use back, the junction of handle and base makes the handle easily become flexible or rock because of wearing and tearing aggravation, and is special, the window often can lead to the vibration because of the speed of air flow is unstable in high-rise building (wind-induced vibration), and then makes the handle that is located on the door and window vibrate thereupon and produce the noise.

In the preferred embodiment, as shown in fig. 3-4, the diameter of the planetary gear 32 is smaller than that of the sun gear 34, specifically, since the planetary carrier 33 is fixed to the handle 1 and the base 2 is fixed to the frame of the door/window, when the handle 1 is rotated, the planetary carrier 33 is driven to rotate, the planetary carrier 33 is used as the input end of the power, the ring gear 31 is fixed to the base 2, i.e., the ring gear 31 is locked, so that the power is output from the sun gear 34 and the rotating shaft 35, and since the diameter of the planetary gear 32 is smaller than that of the sun gear 34, the adjustment of the transmission ratio is realized, i.e., the rotating speed of the rotating shaft 35 is reduced to increase the output torque, and further, the door/window transmission box is driven, and finally the lock body is driven by the transmission box to open or close the door/window, which inevitably generates a certain resistance (machining precision, handle, door handle, etc.) Friction between parts etc. in order to overcome this resistance, often need pay out a lot of power relatively, perhaps the distance that the free end is relative to connecting is longer, promptly, improves the length of the arm of force (handle), adjusts the drive ratio through planetary transmission subassembly 3, can realize the laborsaving operation of handle on the basis that does not need to increase 1 arm of force of handle, and then the light of being convenient for door and window is opened or is closed.
