Specifically, the base 11 includes a seat main body 111 having an arch shape and fixing lugs 112 fixed to both sides of the bottom of the main body. Bolt holes are formed in the fixing lugs 112 in the vertical direction, so that the base 11 can be conveniently fixed on the paraffin slicer through bolts. The seat body 111 has a body hole 113 formed in the middle of the upper side thereof.

Referring to fig. 1 and 2, the connecting sleeve 12 includes a substantially disc-shaped outer disc 121 and an inner sleeve 122 integrally fixed to the inner side of the outer disc 121, the inner sleeve 122 extends toward a side away from the base 11, and a sleeve hole 127 is opened in the center of the inner sleeve 122. Three connecting holes are uniformly formed in the radial outer side of the outer disc body 121 along the circumferential direction, and bolt holes are formed in the outer side wall of the main body hole 113 of the base 11 corresponding to the connecting holes. Thus, the body hole 113 and the sleeve hole 127 can be concentrically arranged by the fixing bolt through the bolt hole in the coupling hole and the base 11.

Referring to fig. 1 and 2, the encoder 2 is inserted into the sleeve hole 127 and fixedly connected with the connecting sleeve 12. Specifically, the encoder 2 may be fixed by mounting a bolt on the inner wall of the inner sleeve 122 in the axial direction to connect the encoder 2. One end of the encoder 2 with the output shaft penetrates out of one side of the connecting sleeve 12, and one side of the encoder 2 with the connecting terminal penetrates out of the base 11.

Referring to fig. 2 and 3, the damping mechanism 4 includes a damping gear 41 and a damping elastic member 42. The damping gear 41 is fixed on the output shaft of the encoder 2 and is located inside the hand wheel body 3. The damping elastic member 42 is fixed to the inner sleeve 122 and disposed radially outside the damping gear 41; the damping elastic member 42 is provided with an abutting portion 423 for abutting and engaging the gear body of the damping gear 41, and the damping elastic member 42 has elastic potential energy sliding toward the axial center side of the damping gear 41. The tooth body is thus constantly in abutment with and disengaged from the abutment portion 423 of the damping elastic member 42 during rotation of the damping gear 41, so that the damping elasticity generates slippage toward and away from the damping gear 41. Therefore, every time the damping gear 41 rotates one tooth body, the damping elastic member 42 and the damping gear 41 are matched to generate one damping feedback.

Specifically, referring to fig. 3 and 4, the damping elastic member 42 is substantially L-shaped, and includes a longer leaf spring main piece 421 and a shorter positioning piece 422. The positioning piece 422 is integrally connected to one end of the plate spring main piece 421, and is perpendicular to the plate spring main piece 421. The inner wall of the inner sleeve 122 is provided with a clamping groove 123 for embedding the two sides of the main leaf spring piece 421, and the clamping groove 123 on one side is communicated with a positioning groove 124 for embedding the positioning piece 422, so that the clamping stability of the damping elastic piece 42 and the inner sleeve 122 is improved.

Further the radius of the abutment roller 425 is slightly larger than the pitch between the two teeth of the damping gear 41 so that the abutment roller 425 does not sink completely into the pitch between the two teeth of the damping gear 41. And the spacing between the two sidewalls of the abutment groove 424 is slightly larger than the radius of the abutment roller 425 so that the abutment roller 425 does not move out of the abutment groove 424.

Further, returning to fig. 2, an outer baffle 126 for blocking the damping elastic member 42 is detachably and fixedly connected to the inner sleeve 122 outside the catching groove 123. The outer baffle 126 is arc-shaped, and both ends of the outer baffle 126 can be fixed on the inner sleeve 122 body through bolts. And in order to save the number of bolts, the outer baffle 126 can be directly fixed by using part of the bolts for fixing the encoder 2.

Referring to fig. 1 and 2, the hand wheel body 3 is fixedly connected to the damping gear 41 through a bolt, so that the hand wheel body 3 and the machine body 1 are rotatably connected, and the rotary hand wheel body 3 can drive the output shaft of the encoder 2 to rotate synchronously. A handle 31 is fixedly connected to the radial outer side of the end surface of one side of the hand wheel body 3 far away from the machine body 1.

The operation process comprises the following steps:

when the hand wheel body 3 is rotated by the handle 31, the hand wheel body 3 drives the damping gear 41 to rotate together, and when the gear body of the damping gear 41 passes through the abutting portion 423 of the damping elastic member 42, the gear body abuts against the abutting roller 425, so that the damping elastic member 42 generates deformation on the side away from the damping gear 41. When the tooth body moves away from the abutting portion 423, the abutting portion 423 loses the abutment, the abutting portion 423 moves toward the damper gear 41 side by the elastic force, and the damper elastic member 42 returns to its original shape. Therefore, every time the damping gear 41 rotates one tooth body, the damping elastic member 42 and the damping gear 41 are matched to generate one damping feedback.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
