Both ends of the transmission rod 2 are respectively provided with accommodating cavities 21 for assembling the connecting block 3 . The left and right outer sides of the accommodating cavity 21 are respectively provided with adjusting holes 22 .

[0028] The connecting block 3 is embedded in the accommodating cavity 21 at both ends of the transmission rod 2. The connecting block 3 can slide back and forth within the space range of the accommodating cavity 21 along the length direction of the transmission rod 2. A locking point 31 is provided on the bottom side thereof, and the locking point 31 follows the connecting block 3 to move within the space range of the accommodating cavity 21; a threaded arc surface 32 is provided in the middle part of the connecting block 3, and an adjusting screw 4 for driving the connecting block 3 to slide along the accommodating cavity 21 is installed in the threaded arc surface 32. The adjusting screw 4 corresponds to the adjusting hole and can be threadedly matched with the threaded arc surface 32 of the connecting block 3. The adjusting screw 4 is rotated along the direction of the adjusting hole 22, and the adjusting screw 4 and the connecting block 3 are relatively displaced through the thread, so that the locking point 31 follows the connecting block 3 to move along the length direction of the transmission rod 2.

[0029] The transmission rod 2 is provided with positioning holes 23 corresponding to the front and rear sides of the accommodating cavity 21 . A receiving block 5 is fixedly mounted in the positioning hole 23 . The receiving block 5 is slidably matched with the connecting block 3 .

The receiving block 5 is composed of a locking portion 51 and a receiving portion 52. The locking portion 51 and the receiving portion 52 are connected up and down to form a "T"-shaped structure. The sliding portion 34 abuts against the receiving portion 52 up and down and slides together to enable the connecting block 3 to slide along the upper side of the receiving block 5.

[0031] Furthermore, a plurality of anti-skid stripes are formed on the upper surface of the locking portion 51 to enhance the anti-skid performance of the receiving block 5 and prevent the receiving block 5 from slipping during use.

[0032] Furthermore, a limiting rod 35 is provided on the upper side of the connection block 3, and a limiting hole 24 is provided on the upper side of the accommodating cavity 21. The limiting rod 35 is received in the limiting hole 24, so that the connection block 3 slides along the length range of the limiting hole 24. Furthermore, a plurality of scales are provided on the side surface of the limiting hole 24, and the positions of the connection block 3 and the locking point 31 are intuitively reflected according to the scales corresponding to the limiting rod 35 in real time.

[0033] Please also read Figure 4 A transmission gear 11 is provided inside the gear box 1, and a plurality of convex strips are provided at the bottom of the transmission rod 2 and mesh with the transmission gear 11 through the convex strips; the transmission gear 11 is provided with a first handle hole 12 along the thickness direction of the gear box 1, and the gear box 1 is provided with a second handle hole 13 corresponding to the first handle hole 12.

[0035] Specifically, the two inner walls of the assembly groove body 7 are respectively provided with assembly convex grooves 71, and the two outer sides of the sliding rod 6 are respectively formed with assembly grooves 61 adapted to the assembly convex grooves 71. The assembly convex grooves 71 and the assembly grooves 61 are adapted to be installed, and the sliding rod 6 slides along the length direction of the assembly groove body 7 according to the position of the connecting block 3.

[0036] Please also read Figure 7 During actual assembly, the adjustable transmission lock box structure is installed on one side of the door and window frame 8, and the assembly groove body 7 is nested and installed along the upper and lower sides of the door and window frame 8. The assembly groove body 7 is fixed after sliding to the designated installation hole position, and the adjustable transmission lock box structure is fixed between the two assembly groove bodies 7. The first handle hole 12 and the second handle hole 13 correspond to the side openings of the door and window frame 8, so that the handle 9 can pass through and be connected to the transmission gear 11. The sliding rods 6 located on both sides of the adjustable transmission lock box structure are connected to the locking point 31, and the adjusting screw 4 is rotated to the locking point 31 position to compensate for the length error of the sliding rod 6 or the transmission rod 2 during production and blanking, so as to avoid the sliding rod 6 at one end from detaching from the assembly groove body 7 due to the movement of the transmission rod 2 during the rotation of the handle 9.
