The corresponding operating angle information is then entered into the system, which serves as the standard for the operating angle of this controller during subsequent use. Currently, the operating angle calibration of the controller is entirely manual. The operator determines the different operating angles of the controller based on feel and experience. Large errors can easily lead to deviations in the calibrated operating angle, thus affecting the normal use of the controller.

[0030] Example 1

[0031] like Figures 1 to 3 As shown, a handle operation angle calibration device is disclosed, including a base 1; further comprising a toggle clamp 2, a rotating shaft 3, a handle clamp 4 and a dial 5 arranged on the base 1 for fixing a handle chassis 6; the rotating shaft 3 is arranged concentrically with the roller in the handle; one end of the handle clamp 4 is connected to the rotating shaft 3 and the other end is connected to the operating rod 7 of the handle; the dial 5 is arranged parallel to the movement direction of the operating rod 7; the top of the dial 7 is provided with a groove 8 corresponding to the angle of the dial 7, and the handle clamp 4 is provided with a protrusion 9 adapted to the groove 8.

[0032] In this embodiment, the base 1 serves as a support platform. A toggle clamp 2 is provided on the upper surface of the base 1. This clamp secures the handle chassis 6 to the base 1, preventing the handle from moving relative to the base 1 when operated. A rotating shaft 3 is provided on the base 1. When the handle is installed, the roller in the handle must be concentric with the rotating shaft 3. A handle clamp 4, located on the base 1, is connected to the rotating shaft 3 at one end and to the handle's operating lever 7 at the other. Therefore, when the handle's operating lever 7 is operated, the handle clamp 4 moves synchronously with the operating lever 7 relative to the base 1. A scale 5 is arranged parallel to the direction of movement of the operating lever 7, with its bottom connected to the base 1. The angle of the scale 5 refers to the angle indicated on the scale 5. The curved top of the scale 5 is interspersed with grooves 8, with different grooves 8 corresponding to different angle values ​​indicated on the scale 5. The handle clamp 4 is provided with corresponding protrusions 9 that mate with the grooves 8. As the handle clamp moves with the operating lever 7, the protrusions 9 pass through different grooves 8 in sequence.

[0033] When the boss 9 moves from the top edge of the dial 5 into the groove 8, and then moves out of the groove 8 until it contacts the top edge of the dial 5, the person operating the operating lever 7 will feel a noticeable jerk. Therefore, whenever a person feels a jerk, it means that the boss 9 and the groove 8 have just fit together. At this time, the angle of the boss 9 corresponding to the dial 5 can be observed, which is also the offset angle of the handle operating lever 7. The position of the operating lever 7 remains unchanged, and this angle is recorded into the handle system to achieve calibration of the handle at this angle. In this way, calibration of different angles is completed in sequence. Through the cooperation of the boss 9 and the groove 8, the movement position of the handle is guaranteed to be consistent at the same movement angle, ensuring the accuracy of the handle when calibrating different operating angles. Through the cooperation of the boss 9 on the handle clamp 4 and the groove 8 on the dial 5, the handle operating angle calibration can be prepared, which has a simple structure and low manufacturing cost.

[0034] Example 2

[0035] Disclosed is a handle operation angle calibration device, comprising a base 1; a toggle clamp 2, a rotating shaft 3, a handle clamp 4, and a scale plate 5, which are arranged on the base 1 for fixing a handle chassis 6; the rotating shaft 3 is arranged concentrically with a roller in the handle; one end of the handle clamp 4 is connected to the rotating shaft 3 and the other end is connected to an operating rod 7 of the handle; the scale plate 5 is arranged parallel to the movement direction of the operating rod 7; the top of the scale plate 7 is provided with a groove 8 corresponding to the angle of the scale plate 7, and the handle clamp 4 is provided with a protrusion 9 adapted to the groove 8.

[0036] The difference between this embodiment and embodiment 1 is that four toggle clamps 2 are provided. The four toggle clamps 2 secure the chassis 6 of the handle, thereby ensuring the stability of the connection between the handle and the base 1. The toggle clamps 2 are conventional technology in the industry.

[0037] In this embodiment, the handle clamp 4 serves as a component connected to the operating rod 7, and the handle clamp 4 moves synchronously with the operating rod 7. The handle clamp 4 specifically includes a column 40 connected to the rotating shaft 3, and a connecting block 41 is specifically connected to the top of the column 40. A clamping opening 42 is provided on the connecting block. After the handle is fixed, the operating rod 7 is clamped in the clamping opening 42. When the operating rod 7 moves, under the action of the clamping opening 42, the connecting block 41 and the column 40 will be displaced synchronously with the operating rod 7. The clamping opening 42 can be specifically set to a groove design that matches the shape of the operating rod 7, which not only ensures the stable connection between the connecting block 71 and the operating rod 7, but also facilitates the disassembly of the two.

[0038] At the same time, in order to ensure that the distance between the column 40 and the scale plate 5 does not change during the movement of the handle clamp 4, a clamping block for clamping the scale plate 5 can be provided on the connecting block 41. Two clamping blocks are provided, which respectively contact the outer walls of the scale plate 5 on both sides.

[0039] In order to further ensure that the displacement of the connecting block 40 is completely consistent with the displacement of the operating rod 7, a sliding groove 10 can be provided on the scale plate 5, and a pin shaft or a rolling shaft is provided between the sliding groove 10 and the clamping block.

[0040] Example 3

[0041] Disclosed is a handle operation angle calibration device, comprising a base 1; a toggle clamp 2, a rotating shaft 3, a handle clamp 4, and a scale plate 5, which are arranged on the base 1 for fixing a handle chassis 6; the rotating shaft 3 is arranged concentrically with a roller in the handle; one end of the handle clamp 4 is connected to the rotating shaft 3 and the other end is connected to an operating rod 7 of the handle; the scale plate 5 is arranged parallel to the movement direction of the operating rod 7; the top of the scale plate 7 is provided with a groove 8 corresponding to the angle of the scale plate 7, and the handle clamp 4 is provided with a protrusion 9 adapted to the groove 8.

[0042] This embodiment differs from Embodiment 2 in that the boss 9 is cylindrical, one end of which is bolted to the connecting block 41. The top of the boss 9, which engages with the groove 8, is rounded. This facilitates the insertion and removal of the boss 9 from the groove 8. It also reduces friction between the boss 9 and the groove 8 when entering and exiting, thereby reducing wear on the boss 9 and the groove 8 and extending the service life of the device.

[0043] Example 4

[0044] Disclosed is a handle operation angle calibration device, comprising a base 1; a toggle clamp 2, a rotating shaft 3, a handle clamp 4, and a scale plate 5, which are arranged on the base 1 for fixing a handle chassis 6; the rotating shaft 3 is arranged concentrically with a roller in the handle; one end of the handle clamp 4 is connected to the rotating shaft 3 and the other end is connected to an operating rod 7 of the handle; the scale plate 5 is arranged parallel to the movement direction of the operating rod 7; the top of the scale plate 7 is provided with a groove 8 corresponding to the angle of the scale plate 7, and the handle clamp 4 is provided with a protrusion 9 adapted to the groove 8.

[0045] The difference between this embodiment and the above embodiment is that there are four grooves 8 on the dial 5, corresponding to 3°, 6°, 9° and 12° marked on the dial 5. Of course, the position and number of the grooves 5 can be set according to actual conditions.

[0046] In this embodiment, the roller heights within handles of different models are not necessarily the same, while the position of the rotating shaft 3 relative to the base 1 is fixed. Therefore, to ensure that the roller within the handle can be concentrically arranged with the rotating shaft 3 when handles of different models are fixed to the base 1, an adjustment block can be provided between the base 1 and the handle chassis 6. The adjustment block can be used to adjust the height deviation between the roller and the rotating shaft 3, thereby making the device applicable to handles of different models, greatly improving the applicability of the calibration device.

[0047] Obviously, the above embodiments are merely examples for the purpose of clearly illustrating the technical solution of the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art would be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
