Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Embodiment 1, as shown in fig. 1 and 2, comprises an outer handle 1, wherein the outer handle 1 is designed as two symmetrical single bodies, and is divided into a first handle 11 and a second handle 12 which can be spliced with each other. On the side of the single body, there is an opening 13, a bearing 15 is mounted on the opening 13, and a pin 14 is connected with the bearing 15.

A movable handle 2 is arranged between the two single bodies, the pin 14 is connected with a connecting shaft, and the connecting shaft passes through a connecting hole 212 on the movable handle 2 and reaches the other single body. And an angle sensor 7 is arranged on the other monomer, such as the second handle 12, and is used for sensing the rotation angle of the connecting shaft. The angle sensor 7 can use any sensing product on the market, and in this embodiment, an angle sensing positioning meter can be adopted, and an inner hole of the angle sensing positioning meter is connected with the connecting shaft, so that the rotating angle of the connecting shaft can be measured.

The movable handle 2 adopts a three-section design, the first section is a connecting part 21, and a connecting hole 212 and a clamping groove 211 are arranged on the first section. The locking groove 211 is used for connecting with the inner core 5. The middle part is designed to be inclined and has a certain radian, and the middle part is a middle extension part 22, the tail end is an operation part 23 and comprises an annular operation ring 231. Wherein, the connecting part 21 is arranged in the outer handle 1, and the operating part 23 is arranged outside the outer handle 1, which is convenient for the user to operate.

When the user presses the operation portion 23 with the palm, the movable handle 2 rotates about the connecting shaft, and the connecting portion 21 moves rearward, that is, rightward in the drawing. As shown in fig. 1, the inner core 5 is moved rearward, i.e., rightward, to pull the chuck 8 to be clamped. During this clamping, a resilient member 6, such as a torsion spring, is provided in the outer handle 1. The torsional spring can be established on the connecting axle, and one end is contradicted with outer handle 1, and the other end is contradicted with movable handle 2, and the user can experience corresponding torsion when rotatory for the feedback is felt to the power when simulating the tight object of operation pincers clamp. The device also has a rotating wheel 3, so that a user can conveniently hold the handle to rotate left and right.

As shown in fig. 3, when the components are connected, a user can operate the outer handle 1 to rotate the wheel 3, so that the wheel 3 and the wheel core 9 rotate relatively. The inside of the rotating wheel 3 is provided with a spring 31, and the tail end of the spring 31 is provided with a top ball 32. And the inner core 9 of the wheel is provided with a plurality of hemispherical grooves which are arranged circumferentially, for example, 12 hemispherical grooves are arranged. When a user rotates the rotating wheel 3, the user has a clear rotating hand feeling, and the rotating hand feeling is generated every 30 degrees because the top bead 32 is pushed into the groove by the spring 31.

The user can use the device to simulate the object to be clamped, the angle sensor 7 can record the rotating angle of the connecting shaft in real time, namely the pressing amplitude of the user to the movable handle 2, and the upper computer processes the obtained potentiometer signals to calculate the clamping or opening angle.

When the user needs to replace the inner core 5, the spring cap in fig. 2 can be pressed down to push the movable handle 2, so that the inner core 5 can be ejected out, and the inner core 5 can be freely replaced.
