[0034] Please also read Figures 1 to 7 Now, the handle provided by the present invention is described. The handle comprises: a shell 1 and a filling block 2; the shell 1 has a front side wall 11 and a rear side wall 12 for mounting on a predetermined object, and the shell 1 has a left side wall 13 and a right side wall 14; the left side wall 13 is recessed to form a first concave cavity 15, and the right side wall 14 is recessed to form a second concave cavity 16; the filling block 2 is filled in the first concave cavity 15, and the filling block 2 is detachably fixed to the shell 1; or the filling block 2 is filled in the second concave cavity 16, and the filling block 2 is detachably fixed to the shell 1.

[0035] In this way, the shell 1 can be fixed on the door / drawer by the rear side wall 12 for use, and the user can pull the door / drawer to move by grasping the shell 1; the left side wall 13 of the shell 1 has a first cavity 15, and when the filling block 2 is filled in the first cavity 15, the user's fingers can be inserted into the second cavity 16 to facilitate the movement of the pulling shell 1; the right side wall 14 of the shell 1 has a second cavity 16, and when the filling block 2 is filled in the second cavity 16, the user's fingers can be inserted into the first cavity 15 to facilitate the movement of the pulling shell 1; since the first cavity 15 is arranged on the left side wall 13 and the second cavity 16 is arranged on the right side wall 14, the user can switch between the first cavity 15 and the second cavity 16 by the filling block 2 to choose whether the first cavity 15 or the second cavity 16 cooperates with the user's fingers; during use, the first cavity 15 / the second cavity 16 near the door can be filled by the filling block 2 to avoid the user's fingers being stuck in the first cavity 15 / the second cavity 16 near the door and injuring the fingers.

[0036] Specifically, in one embodiment, the predetermined object is a door.

[0037] Specifically, in one embodiment, the outer contour of the filling block 2 is the same as that of the first cavity 15 .

[0038] Specifically, in one embodiment, the outer contour of the filling block 2 is the same as that of the second cavity 16 .

[0039] Specifically, in one embodiment, the first cavity 15 and the second cavity 16 are the same.

[0040] Specifically, in one embodiment, the housing 1 and the filling block 2 are respectively an integral part made of plastic. Specifically, in one embodiment, the housing 1 and the filling block 2 are respectively an integral part made of metal.

[0041] Specifically, in one embodiment, the front side wall 11 and the rear side wall 12 form an angle of 0° to 30°. In this way, the rear side wall 12 is usually installed vertically on the door, and when the user's hand contacts the front side wall 11, the user's hand is not easy to slide down along the front side wall 11.

[0042] For further information, see Figures 1 to 7 As a specific embodiment of the handle provided by the present invention, the rear side wall 12 is recessed to form a recessed space 17, and the first concave cavity 15 and the second concave cavity 16 are separated by the recessed space 17. In this way, the existence of the recessed space 17 can reduce the weight of the housing 1. In addition, the recessed space 17 can provide a space for buffering deformation during the deformation of the first concave cavity 15 or the second concave cavity 16.

[0043] For further information, see Figures 1 to 7As a specific embodiment of the handle provided by the present invention, the left side wall 13 is a plane and is located on the first plane, and the right side wall 14 is a plane and is located on the second plane; when the filling block 2 is filled in the first concave cavity 15, the surface of the filling block 2 is flush with the first plane, or the filling block 2 is located in the space surrounded by the inner wall of the first concave cavity 15 and the first plane; when the filling block 2 is filled in the second concave cavity 16, the surface of the filling block 2 is flush with the second plane, or the filling block 2 is located in the space surrounded by the inner wall of the second concave cavity 16 and the second plane.

The right side wall 14 is a plane and is located on the second plane, so as to prevent the user's hand from being scratched or bumped when in contact with the right side wall 14; when the filling block 2 is filled in the second concave cavity 16, if the surface of the filling block 2 is flush with the second plane, the user's hand is not likely to bump the user's fingers when sliding from the right side wall 14 to the surface of the filling block 2; when the filling block 2 is filled in the second concave cavity 16, if the surface of the filling block 2 is located in the space enclosed by the plane where the second plane is located and the inner wall of the second concave cavity 16, the user can feel the height difference between the right side wall 14 and the surface of the filling block 2 when transitioning along the second plane to the surface of the filling block 2, so that the user can locate the filling block 2 more quickly, which is convenient for replacing the filling block 2.

[0044] For further information, see Figures 1 to 8 As a specific embodiment of the handle provided by the present invention, in the direction perpendicular to the first plane, the cross section of the first cavity 15 is a predetermined quadrilateral 3; in the direction perpendicular to the second plane, the cross section of the second cavity 16 is a predetermined quadrilateral 3. In this way, the filling block 2 filled in the first cavity 15 is not easy to rotate, and the filling block 2 filled in the second cavity 16 is not easy to rotate.

[0045] For further information, see Figures 1 to 8As a specific embodiment of the handle provided by the present invention, the predetermined quadrilateral 3 has a first side 32 and a second side 31 that are arranged opposite to each other; there is an angle of 0° to 60° between the first side 32 and the second side 31. In this way, after the filling block 2 is filled in the first concave cavity 15, it is not easy to be installed incorrectly. When the inner wall corresponding to the non-parallel second side 31 and the inner wall corresponding to the first side 32 clamp the filling block 2 in the middle, moving the filling block 2 toward the intersection of the first side 32 and the second side 31 can improve the tightness of the contact between the filling block 2 and the second side 31 and the first side 32; moving the filling block 2 away from the intersection of the first side 32 and the second side 31 can reduce the tightness of the contact between the filling block 2 and the inner wall corresponding to the second side 31 and the inner wall corresponding to the first side 32.

[0046] Specifically, in one embodiment, the predetermined quadrilateral 3 has a third side and a fourth side that are relatively arranged; the first side, the third side, the second side, and the fourth side are connected in sequence; the third side is located on the side where the distance between the first side and the second side is gradually reduced, the third side is shorter than the fourth side, and the angle between the third side and the second side is 60° to 90°; in this way, it is assumed that the inner wall of the first concave cavity 15 corresponding to the first side is the first wall, the inner wall of the first concave cavity 15 corresponding to the second side is the second wall, the inner wall of the first concave cavity 15 corresponding to the third side is the third wall, and the inner wall of the first concave cavity 15 corresponding to the fourth side is the fourth wall; in the process of the first wall and the second wall approaching each other during deformation, the third wall having a larger angle with the second wall can effectively resist the extrusion and is not easy to cause the third wall to bend. In addition, in one embodiment, the situation of the first concave cavity 15 is the same as that of the second concave cavity 16.

[0047] For further information, see Figures 1 to 7 As a specific embodiment of the handle provided by the present invention, the first cavity 15 and the second cavity 16 are symmetrically arranged on opposite sides of a predetermined symmetry plane. In this way, the first cavity 15 and the second cavity 16 are plane-symmetrical, which facilitates the user's hands to engage with the first cavity 15 and the second cavity 16 from two opposite directions.

[0048] For further information, see Figures 1 to 7 As a specific embodiment of the handle provided by the present invention, a first convex rib 181 surrounding the outside of the first concave cavity 15 is provided on the left side wall 13, and / or a second convex rib 182 surrounding the outside of the second concave cavity 16 is provided on the right side wall 13. In this way, the first convex rib 181 and the second convex rib 182 facilitate the user to increase the friction when grasping the handle.

[0049] Specifically, in one embodiment, the first convex rib 181 is located at the edge of the first concave cavity 15. In this way, the edge of the first concave cavity 15 is not easily deformed. Specifically, in one embodiment, the second convex rib 182 is located at the edge of the second concave cavity 16. In this way, the edge of the second concave cavity 16 is not easily deformed.

[0050] Specifically, in one embodiment, the first convex rib 181 is arranged along the edge of the front side wall 11 and protrudes on the outside of the front side wall 11, and the second convex rib 182 is arranged along the edge of the front side wall 11 and protrudes on the outside of the front side wall 11. In this way, the deformation resistance of the front side wall 11 is enhanced. Specifically, in one embodiment, the first convex rib 181 and the second convex rib 182 are connected at the end in a ring shape. In this way, the first convex rib 181 and the second convex rib 182 share the tension with each other, which is conducive to maintaining the stability of the shape of the front side wall 11.

[0054] Specifically, in one embodiment, the cross section of the recessed portion 21 is similar to the predetermined quadrilateral 3 .

[0055] Specifically, in one embodiment, the recessed portion 21 has a predetermined planar bottom wall, a predetermined planar left wall, a predetermined planar right wall, a predetermined planar front wall, and a predetermined planar rear wall, so that the processing is convenient.

[0056] Specifically, in one embodiment, at least one positioning column 22 is disposed at the intersection of the predetermined bottom wall and the predetermined side wall, so that the lifting positioning column 22 can be more firmly in contact with the inner wall of the recessed portion 21 .

[0057] Specifically, in one embodiment, at least one positioning column 22 is located in the central area of ​​the predetermined bottom wall. In this way, when the positioning column 22 is subjected to tension, it is easy to distribute it to the predetermined bottom wall. Specifically, in one embodiment, at least one positioning column 22 is parallel to the predetermined front wall and the predetermined rear wall, and the distances between the positioning column 22 and the predetermined front wall and the predetermined rear wall are the same, so as to avoid the positioning column 22 from hitting the predetermined front wall or the predetermined rear wall when deforming.

[0058] Specifically, in one embodiment, the recessed space 17 has a first boss 191, and a portion of the first cavity 15 is formed in the first boss 191. In this way, the first cavity 15 is supported by the first boss 191, and the first boss 191 can reduce the deformation generated when the filling block 2 (or the user's finger) contacts the first cavity 15. In addition, the force when the filling block 2 (or the user's finger) contacts the first cavity 15 can be transmitted to the inner wall of the recessed space 17 through the first boss 191. Specifically, in one embodiment, the recessed space 17 has a second boss 192, and a portion of the second cavity 16 is formed in the second boss 192. In this way, the second cavity 16 is supported by the second boss 192, and the second boss 192 can reduce the deformation generated when the filling block 2 (or the user's finger) contacts the second cavity 16. In addition, the force when the filling block 2 (or the user's finger) contacts the second cavity 16 can be transmitted to the inner wall of the recessed space 17 through the second boss 192. In addition, the first boss 191 can transmit force to the second boss 192 through the surface (i.e., the inner wall of the recessed space 17) through the inner wall of the recessed space 17, and the first boss 191 and the second boss 192 are arranged at an interval, so the deformation between the first boss 191 and the second boss 192 can be released.

[0059] Specifically, in one embodiment, the first boss 191 has a fifth wall facing the second boss 192, and the second boss 192 has a sixth wall facing the first boss 191.
