On the opposite ends of the two claws, there are protruding blocks, and the surface of the block facing away from the circular convex block extends obliquely towards the circular convex block. The potentiometer is sleeved on the two claws, and the block is outside the sleeving hole. The two claws are the claw part; during application, the potentiometer 71 is limited and clamped on the limiting piece 113. When the rotating shaft rotates, the clamping block 81 will not affect the rotation of the rotating shaft. The setting of the two claws further restricts the potentiometer from disengaging outward. At the same time, both ends of the rotating shaft of the large swing have rotating bearings, and both ends of the rotating shaft of the small swing arm have rotating bearings. In this way, there are rotating bearings in all four directions. When controlling the rotation of the rocker, the rotation is stronger, and the rotation feel and reset performance of the control device are better.

The lower jacking block 82 is of a strip-shaped sheet structure arranged horizontally, and the lower jacking block 82 is located on the bottom surface of the upper sleeve body 81 and is vertically arranged with respect to the upper sleeve body 81. The bottom surface of the lower jacking block 82 is a horizontally arranged lower cutting plane 821, and arc-shaped jacking blocks 822 protrude upward at both ends of the top surface of the lower jacking block 82. The first spring arm and the second spring arm are both strip-shaped blocks 9. One end of the strip-shaped block 9 has a hinge shaft 91. The hinge shaft is hinged to the hinge connection block, that is, a hinge groove for the hinge shaft to extend into is recessed on the bottom surface of the hinge connection block. A hook portion 92 protrudes on the second end surface of the strip-shaped block 9. The hook portion 92 is located above one side of the first end of the strip-shaped block 9 and is arranged vertically opposite to the corresponding hook portion 63. Both ends of the spring are hooked to the hook portion 92 and the hook portion 63 respectively. The bottom surface of the strip-shaped block 9 successively has a first inclined surface 931, a first horizontal surface 932, a vertical surface 933, an arc surface 934, a second inclined surface 935 and a second horizontal surface 936. The first inclined surface 931 extends upward obliquely from the bottom surface of the hinge shaft 91. The vertical surface 933 is relatively parallel to and tightly attached to the upper cutting plane 811 at the first end of the upper sleeve body 81. The top surface of the upper sleeve body 81 is within the range of the arc surface 934. The second inclined surface 935 is inclined downward away from the upper sleeve body 81. The top surfaces of the two above-mentioned lifting blocks 8 are respectively in contact with the first horizontal surface 932 and the second horizontal surface 936. The top surface of the strip-shaped block 9 successively has a third inclined surface 941, a fourth inclined surface 942 and a third horizontal surface 943.

[0030] A rocker potentiometer of the present utility model, during assembly, rotation bearings are sleeved on the rotating shafts at both ends of the small rocker arm 3 and the rotating shafts at both ends of the large rocker arm 2. The first end of the first spring arm is hinged to the base 11 through a hinge shaft and a hinge connecting block. At the same time, the upper end of the first spring 41 is hooked on the hook portion 92 of the first spring arm. The lower end of the first spring 41 is buckled with the hanging portion 63 of the mounting block 6. The vertical portion of the mounting block 6 is locked with the strip-shaped vertical block, thus completing the installation of the first spring arm and the base 11. Then, the large rocker arm 2 is aligned and inserted into the hollow chamber of the base 11. The sleeve body 81 on the front side of the large rocker arm falls within the range of the arc surface of the first spring arm. The arc-shaped top blocks 822 at both ends of the front side of the large rocker arm press against the first horizontal straight surface 932 and the second horizontal straight surface 936 of the first spring arm. The locking piece 51 is locked with the square seat body on the front end of the large rocker arm. Moreover, the rotation bearing on the front end of the large rocker arm falls into the through hole between the square seat body 5 and the locking piece 51. The rotation bearing at the rear end of the large rocker arm extends into the rotation groove of the limiting piece 113. The potentiometer 71 is clamped in the limiting groove, and the end of the rotation shaft at the rear end of the large rocker arm is embedded in the embedding hole of the clamping block 81. The limiting piece 113 is locked on the bottom surface of the base, thus completing the installation of the large rocker arm. Then, the small rocker arm is inserted into the hollow chamber of the large rocker arm. Similarly, the installation of both ends of the small rocker arm is similar to the installation of both ends of the large rocker arm. Finally, the decorative cover plate is locked on the base to complete the assembly. During application, the rocker potentiometer is installed on the control device. When the rocker is rotated forward and backward, the rocker drives the small rocker arm to swing forward and backward. When the rocker is rotated left and right, the rocker drives the large rocker arm to swing left and right. The swing signals of the small rocker arm and the large rocker arm are output through the potentiometer. Compared with the prior art, the corresponding decorative cover plate can be replaced according to the needs of the control device to adapt to different styles of control devices. Moreover, when installing the spring, the two ends of the spring can be hooked first and then installed, without the need to use external tools for buckling during the installation process, which is simple and convenient to operate. In addition, the lower end of the spring is hooked on the mounting block. When the mounting block is damaged, only the mounting block needs to be replaced correspondingly, and the replacement cost is relatively low. Furthermore, the setting of the bottom cover is omitted, which also reduces the processing cost.

[0031] In the present invention, it is preferred that the sensor is a Hall chip 72, which is positioned in the limiting groove, and a set through hole is provided on the Hall chip 72, and the ejection structure is a limiting block 82, which is within the range of the limiting groove, and an embedding through hole is provided on the limiting block 82, which passes through the limiting block 82 and is provided for the fourth rotating shaft or the second rotating shaft to be embedded therein, and the limiting block 82 has a reduced diameter section and an expanded diameter section, and the reduced diameter section is on the side of the expanded diameter section facing the limiting groove, and the Hall chip 72 is mounted on the reduced diameter section; when used, the Hall chip 72 is limited in the limiting groove under the limiting action of the limiting block 82, and the Hall chip 72 is mounted together with the limiting block 82, so that the limiting block can rotate with the rotating shaft; the sensor can be replaced as needed, and the sensor can be limitedly installed by simply replacing the ejection structure accordingly.

[0032] In the present invention, it is preferred that an arc block is convexly provided on the bottom surface of the large rocker arm downward, and an elastic iron sheet (not shown in the figure) is provided on the bottom surface of the base to press against the arc block; when used, the elastic iron sheet can clamp the arc block of the large rocker arm, so that the hand feel is better during the rotation of the large rocker arm.

[0033] The product form of the utility model is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the utility model.
