Both ends of the drive section 2 are provided with flat parts. A transition ring 3 is provided near one end of the drive section 2. A limit adjustment seat 4 is sleeved outside the transition ring 3. Two locking parts 5 are penetrated between the other end of the drive section 2 and the rod body 1. A gasket 6 and a locking bearing 7 are sequentially sleeved on one side of the rod body 1 away from the locking part 5 for the neat installation of the drive section 2 and the rod body 1. Among them, through the structural improvement of the drive section 2 and the structural settings at both ends of the drive section 2, it is convenient to limit and install the drive section 2 on the rod body 1, and it is convenient for the neat installation between the drive section 2 and the rod body 1. And through the use of the locking bearing 7, the other end of the drive section 2 can be limited to prevent the position of the drive section 2 on the rod body 1 from loosening, and the structural integrity between the drive section 2 and the rod body 1 is increased; it is worth noting that the rotation direction of the locking bearing 7 is set in the same direction as the use rotation direction of the drive section 2. When the rod body 1 drives the drive section 2 to rotate at an angle, the locking bearing 7 is simultaneously driven to rotate, and the drive section 2 and the locking bearing 7 are in a static state with respect to each other. Therefore, the locking bearing 7 can prevent the drive section 2 and the rod body 1 from loosening; when installing the drive worm, through the use of the limit adjustment seat 4, the distance between the installation section and the drive section 2 can be adjusted, the distance between the teeth of the drive section 2 and the teeth of the drive worm wheel can be changed, so that the teeth on the drive section 2 are aligned and meshed with the teeth on the worm wheel, avoiding the offset wear between the teeth, and increasing the service life of the drive worm.
[0027] In order to better adjust the position of the drive section 2 on the rod body 1, in some embodiments, such as Figure 2 and Figure 5 shown, a connecting block 31 can be provided on the transition ring 3 to facilitate the limit connection between the transition ring 3 and the limit adjustment seat 4, and the end of the connecting block 31 extends outward and can penetrate the outside of the limit adjustment seat 4, which is convenient for external installers to adjust the gap between the limit adjustment seat 4 and the transition ring 3 by hitting or prying the connecting block 31 towards the drive section 2; and through the sleeving of the transition ring 3 and the limit adjustment seat 4, it is convenient for the dust prevention treatment of the drive section 2, avoiding dust hiding in the gap, increasing the weight and heat of the drive worm, and reducing the service life of the drive worm.
[0028] In order to facilitate better adjustment of the distance between the drive section 2 and the limit adjustment seat 4, in some embodiments, such as Figure 5As shown, by using the limit adjustment seat 4, the side clearance between the worm transmission section 2 and the connected worm wheel can be adjusted to avoid offset wear between the worm wheel and the worm; the limit adjustment seat 4 is provided with an adjustment groove 42 that cooperates with the connecting block 31, and a plurality of rough strips 421 are provided on the adjustment groove 42.

A plurality of clamping plates 43 cooperating with the flattened portion are provided on the peripheral side of the limit adjustment seat 4. By using a plurality of clamping plates 43, the transition ring 3 can be limited to achieve the limitation of the transmission section 2. A clamping ring 41 cooperating with the transition ring 3 is provided on the limit adjustment seat 4, and the clamping ring 41 has a table-like tubular structure.
[0030] In order to better connect the transmission section 2 and the rod body 1 neatly, as Figure 4 As shown, a locking groove 21 cooperating with the locking member 5 can be opened on the inner side of the transmission section 2, and an elastic sheet 22 is fixed to the bottom of the locking groove 21. Through the arrangement of the locking groove 21 and the elastic sheet 22, it is convenient for the locking member 5 to detachably limit the position between the transmission section 2 and the rod body 1, providing conditions for the neat installation of the locking member 5 and the transmission section 2, and increasing the integrity between the locking member 5, the transmission section 2 and the rod body 1. It is worth mentioning that the elastic sheet 22 is a U-shaped structure, one end of the elastic sheet 22 is fixed on the transmission section 2, and when the locking member 5 passes through the middle of the elastic sheet 22, the other end of the elastic sheet 22 will be stretched open and pressed against the rod body 1, so as to achieve the limiting of the locking member 5 in the locking groove 21.
[0031] In order to limit the connection between the transmission section 2 and the rod body 1 and facilitate the connection between the locking piece 5 and the transmission section 2 and the rod body 1, a penetrating block 51 with a sharp structure is set at one end of the locking piece 5 that penetrates the transmission section 2, and the other end is set to a fitting portion 52 that can be clamped with the transmission section 2; when the locking piece 5 is installed and used, the sharp end will penetrate the locking groove 21 and enter the transmission section 2, and penetrate the elastic sheet 22 through the small face end of the sharp end to facilitate the locking piece 5 to limit the locking of the transmission section 2 and the rod body 1; the fitting portion 52 fits on the surface of the transmission section 2 to seal the transmission section 2.
