[0023] In order to help those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, an embodiment of the present invention provides a hand-cranked side-flipping stem grinder cover, comprising a cover body 1, a support 2, a hinge unit 3, a hand-cranked mechanism 4 for controlling the opening and closing of the cover body 1, and a torsion spring 6. The hinge unit 3 is fixed to the cover body 1 by a detachable connection, and the support 2 is connected to the body 5 of the stem grinder by a detachable connection. The support 2 serves to connect the cover body 1 and the body 5 of the stem grinder. The hand-cranked mechanism 4 is installed in the support 2, and a buffer rubber 8 is provided on the support 2. The function of the buffer rubber 8 is to prevent collision between the cover body 1 and the support 2 when the cover body 1 is opened to the extreme position. The torsion spring 6 is sleeved on the rotating shaft 7, and both ends of the rotating shaft 7 are fixed to the support 2 through end covers.

[0025] In this embodiment, the hand-crank mechanism 4 includes a handwheel 41, a worm 42, and a worm gear 43. The handwheel 41 is located at one end of the worm 42, which is located below the worm gear 43. The worm gear 43 is connected to the hinge unit 3 via a rotating shaft 7 (the worm gear 43 is fixed to the rotating shaft 7). Because the worm gear 43 and worm 42 are self-locking, the lid 1 can be opened and held at any angle. To open the lid 1, simply turn the handwheel 41. The torsion spring 6 saves effort during opening and acts as a buffer against gravity when closing the lid 1.

[0026] In this embodiment, the hinge unit 3 includes a hinge 31 and a spring clip 32. The spring clip 32 is fixed to the support 2 by screws. One end of the hinge 31 is connected to the cover body 1 by screws. The other end of the hinge 31 is hollow cylindrical and is sleeved on the rotating shaft 7. The rotating shaft 7 and the hinge 31 are connected by an axial hole. There is a keyway on the rotating shaft 7 and there is also a keyway on the sleeve hole of the hinge 31. The two complete the rotation limit through the key.

[0027] In this embodiment, the number of torsion springs 6 is two, and the two torsion springs 6 are symmetrically distributed on both sides of the hinge 31. One end of the torsion spring 6 is clamped on the support 2 and fixed, and the other end is fixed on the side of the hinge 31 by the spring clamping strip 32 through a screw. The main function of the torsion spring 6 is to assist in saving labor when the cover body 1 is opened and to buffer when the cover body 1 is closed.

[0028] In this embodiment, the cover body 1 is arranged above the body 5 of the stem grinding machine. The cover body 1 is a curved surface structure, and the lower edge of the cover body 1 is provided with a skirt 11 arranged along the circumference of the cover body 1. The body 5 of the stem grinding machine is provided with a sealing structure 51 matched with the skirt 11.

[0029] When the cover body 1 needs to be opened, the hand wheel 41 is manually rotated counterclockwise. The hand wheel 41 is installed at the shaft end of the worm 42 and is limited in the radial and axial directions by a key and an end cap. When the hand wheel 41 is rotated, the worm 42 is driven to rotate. The worm 42 and the worm gear 43 are engaged, and the movement is transmitted to the worm gear 43 through the worm 42. The worm gear 43 is installed on the rotating shaft 7 and is limited in the radial and axial directions by a key and an end cap. The rotation of the worm gear 43 drives the rotating shaft 7 to rotate. The rotating shaft 7 is fixed at both ends to the support 2 through an end cap. The hinge 31 (structure as shown in Figure 3 The hinge 31 is matched with the rotating shaft 7 through a shaft hole and is fixed together by a key. Therefore, the hinge 31 rotates together with the rotating shaft 7. The hinge 31 is connected to the cover body 1 by a screw, and the hinge 31 rotates to drive the cover body 1 to rotate synchronously. Two torsion springs 6 are arranged on the rotating shaft 7 and are symmetrically distributed on both sides of the hinge 31. One end of the torsion spring 6 is clamped on the support 2 and fixed, and the other end is fixed on the side of the hinge 31 by the spring clamping strip 32 through a screw. When the cover body 1 is opened upward, i.e., the rotating shaft 7 rotates counterclockwise, the torsion spring 6 is released, which assists in saving labor. When the cover body 1 is closed, the torsion spring 6 is compressed, which buffers.

[0030] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
