[0050] With reference to Figure 5 , With Figure 6The second insertion hole 1221 is a strip-shaped hole; the second insertion hole 1221 is horizontally arranged; the width of the second insertion hole 1221 is matched with the diameter of the rotating shaft 2; the maximum diameter position of the rotating shaft 2 is matched with the top and bottom surfaces of the second insertion hole 1221 through a gap, so that the rotating shaft 2 can stably slide in the second insertion hole 1221.

[0051] With reference to Figure 4 And Figure 8 The outer side wall of the second base 121 is provided with an inclined surface 1211; the connecting piece 1 is arranged in the guide plate 3 and can slide along the guide plate 3; the inclined surface 1211 of the outermost second base 121 is slidingly connected with the side wall 31 of the guide plate; the normal line of the inclined surface 1211 points to the oblique front of the moving direction of the connecting piece 1, so that the inclined surface 1211 is used to guide the connecting piece 1 (when there is to avoid); when the connecting piece 1 is bent, the outermost end of the inclined surface 1211 abuts against the inner side wall of the guide plate 3, so that the friction is reduced and the operation fluency is improved.

[0052] With reference to Figure 4 And Figure 8 The cross section of the second base 121 is isosceles trapezoidal. The second base 121 is provided with a plane; the inclined surface of the connecting piece 1 is used to move in the direction (instead of using the bottom surface of the trapezoid to face the moving direction of the connecting piece 1), so that the problem of being stuck can be effectively avoided (the side wall 31 of the guide plate has a joint; when the bottom surface of the trapezoid faces the moving direction of the connecting piece 1, the tip of the side edge position of the second base 121 is stuck by the joint).

[0055] The plugging member includes a cylinder, barbs, and a stop protrusion. The cross-section of the cylinder is adapted to the cross-section of the second jack 1221, so the cylinder can be inserted into the second jack 1221. There are two barbs, which are respectively fixedly installed on the top and bottom surfaces of the cylinder (for example, through an integral fixed connection).

There are two stop protrusions, which are respectively fixedly installed on the top and bottom surfaces of the cylinder (for example, through an integral fixed connection). The side wall of the stop protrusion abuts against the outer side wall of the second rod 122, thus preventing the problem that the rotating shaft 2 is stuck due to the cylinder moving inward excessively and ensuring the smooth swing of the rotating shaft 2. Assembly personnel can conveniently insert and snap the plugging member at the outermost side wall position of the outermost connecting member 1 by using the barbs and the stop protrusions.

To minimize the weight of the present utility model, the connecting member 1 and the rotating shaft 2 are usually made of lightweight materials (such as plastics); during the movement of the present utility model, the steel balls are affected by the vibration force and the inertia effect and thus roll / bounce inside the inner cavity of the cylinder, causing the steel balls to impact the inner wall of the cylinder, thereby greatly increasing the vibration intensity. This vibration is transmitted to the connecting member 1 and causes the vibration of the connecting member 1 to shake off the impurity particles or material particles夹杂 in the gaps of the present utility model and avoid the problem that the connecting member 1 is stuck, ensuring the smooth transmission of the present utility model.

[0057] See Figure 9 , there are two supporting feet 41 on the bottom surface of the sealing plate 4 (for example, through an integral fixed connection). The bottom ends of the two supporting feet 41 are respectively snapped onto the inner wall at the top end of the water permeable hole 1222. There are protrusions on the outer side wall at the bottom end of the supporting feet 41, and there are grooves on the inner wall at the top end of the water permeable hole 1222 that are adapted to the protrusions, so the supporting feet 41 are snapped into the grooves through the protrusions to achieve snap connection; the supporting feet 41 and the sealing plate 4 are connected in a π shape, and the two supporting feet 41 are respectively snapped onto the two opposite side walls of the water permeable hole 1222, thus achieving support; the sealing plate 4 is pressed against the top surface of the second rod 122, thus achieving the plugging of the water permeable hole 1222 to prevent impurity particles and material particles from falling into the water permeable hole 1222 and avoid the problem that the rotating shaft 2 is stuck (after the impurity particles / material particles fall into the water permeable hole 1222, the impurity particles / material particles are squeezed by the end surface of the rotating shaft 2 and the end surface of the cylinder, or the impurity particles / material particles are squeezed by the end surface of the rotating shaft 2 and the side wall of the abutting portion 412, both of which will cause the rotating shaft 2 to be stuck).
