The handle 40 includes an operating portion 41, a rod portion 43, and a fixing portion 45, which are fixedly connected in sequence, that is, the rod portion 43 connects the operating portion 41 and the fixing portion 45. The operation portion 41 may be a circular body, a rectangular body, or a square body or other shapes as long as the operation is convenient for the hand of the user. In this embodiment, the operation portion 41 is a circular body, and the cross-sectional dimension of the operation portion 41 is larger than the cross-sectional dimensions of the rod portion 43 and the fixing portion 45. When no external force is applied to the handle 40, the handle 40 extends through the first through hole 1312 in the Z-axis direction. The operation portion 41 is located outside the accommodating space 15 formed by the housing 10, and facilitates the user to operate the handle 40. The rod 43 is inserted into the accommodating space 15 from the first through hole 1312 of the top wall 131, and in the embodiment, the magnet 20 is located inside the rod 43 and is fixedly connected to the rod 43.

The first limiting member 50 includes a first main body 51 and first catches 53 disposed on two sides of the first main body 51, and the first catches 53 extend along the X-axis direction. The first body 51 corresponds to the handle 40, the first body 51 has a receiving cavity 515 matching with the fixing portion 45, and the fixing portion 45 is received in the receiving cavity 515 to fix and support the handle 40. In the embodiment, the accommodating groove 515 is a substantially flat ellipsoidal groove, and when the fixing portion 45 is accommodated in the accommodating groove 515, the handle 40 can be prevented from rotating relative to the first limiting member 50 to generate an invalid motion, which affects user experience. In some embodiments, the handle 40 may be secured and supported in other ways, such as by adhesive.

The first retaining part 53 is a cylinder, and the first retaining part 53 extends along two opposite ends of the first main body part 51. The first main body 51 is located in the accommodating space 15, the first latching portions 53 located at two ends of the first main body 51 respectively penetrate through the first opening 1332 and the second opening 1372, and a certain first gap 535 is formed between the surface of the first main body 51, which is used for connecting the first latching portion 53, and the first side wall 133 and/or the second side wall 137, so that the first limiting member 50 has a moving space in the accommodating space 15; the first opening 1332 and the second opening 1372 are matched with each other, so that the first position-limiting member 50 has a movable space in the XY plane.

The second limiting member 60 includes a second main body portion 61 and second latching portions 63 disposed at two sides of the second main body portion 61, the second catch 63 extends in the Y-axis direction. The second main body portion 61 is provided with a second through hole 615, the second through hole 615 is long, for example, rectangular, the second through hole 615 is used for the rod portion 43 of the handle 40 to penetrate through the second through hole 615, wherein the fixing portion 45 is a flat ellipsoid, which is also beneficial for the handle 40 to pass through the second through hole 615. The second through hole 615 has a width along the X-axis direction and a length along the Y-axis direction, the length is greater than the width, and the length is greater than the fixing portion 45 along the X-axis direction, so that the fixing portion 45 can pass through the second through hole 615; the width is slightly larger than the diameter of the rod portion 43 and smaller than the dimension of the fixing portion 45 along the Z-axis direction, so that after the fixing portion 45 passes through the second through hole 615 and rotates, the fixing portion 45 can abut against the second main body portion 61. The second body portion 61 is substantially "concave" and the surface of the second body portion 61 facing away from the fixing portion 45 is concave, so that the second body portion 61 can be connected with the elastic member 70 while the first body portion 51 is accommodated in the concave space of the second body portion 61. The second catching portion 63 is a cylinder, and the second catching portion 63 extends along two opposite ends of the second body portion 61. The second main body part 61 is located in the accommodating space 15, the second clamping parts 63 located at two ends of the second main body part 61 respectively penetrate through the third opening 1352 and the fourth opening 1392, and a certain second gap 635 is formed between the surface of the second clamping part 63, which is used for connecting the second main body part 61, and the third side wall 135 and/or the fourth side wall 139, so that the second limiting part 60 has a movement space in the accommodating space 15; the third opening 1352 and the fourth opening 1392 cooperate with the second gap 635, so that the second limiting member 60 has a movable space in the XY plane.

The elastic element 70 is located on the surface of the base 11 facing the cover 13 and is accommodated in the accommodating space 15, one side of the elastic element 70 is connected to the base 11, and the other side of the elastic element 70 is connected to the first limiting element 50 and the second limiting element 60. In this embodiment, the elastic member 70 is a compression spring.

Specifically, the first main body 51 of the first limiting member 50 is connected to the elastic member 70, the second main body 61 of the second limiting member 60 is connected to the elastic member 70, and the elastic member 70 is in a compressed state. Under the elastic action of the elastic member 70, on one hand, the first latching portion 53 of the first limiting member 50 can be latched in the first opening 1332 and the second opening 1372, and the second latching portion 63 of the second limiting member 60 can be latched in the third opening 1352 and the fourth opening 1392; on the other hand, the side of the fixing part 45 away from the base 11 is abutted against the second main body part 61, so that the handle 40 can be kept perpendicular to the XY plane, and the handle 40 extends along the Z-axis direction. In addition, the contact points of the fixing portion 45 and the second body portion 61 determine the swing fulcrum of the handle 40, and in the present embodiment, there are two contact points, and the center of the two contact points can be regarded as the swing fulcrum.

Due to the position relationship between the first limiting member 50 and the first opening 1332 and the second opening 1372, and the position relationship between the second limiting member 60 and the second through hole 615, the third opening 1352, and the fourth opening 1392, the handle 40 is limited to perform a cone-pendulum motion along the Z-axis direction, wherein the handle 40 drives the second limiting member 60 to move during the swinging process, and the fulcrum of the cone-pendulum motion also changes correspondingly in a three-dimensional space.

When an external force acts on the operating portion 41 of the handle 40 along the X-axis direction, since the fixing portion 45 of the handle 40 is fixedly connected to the first limiting member 50, the swing fulcrum (located on a side of the fixing portion 45 facing the rod portion 43) is located between the operating portion 41 and the fixing portion 45, and the first limiting member 50 is movably clamped in the first opening 1332 and the second opening 1372, the first limiting member 50 swings along a direction opposite to the X-axis direction, and the elastic member 70 deforms; when the external force is lost, the elastic member 70 is deformed again, and the first limiting member 50 is restored to the initial position under the action of the elastic member 70 and simultaneously drives the handle 40 to be restored to the initial position. In the process of deformation of the elastic element 70, the second limiting element 60 is also driven to displace.

When an external force acts on the operating portion 41 of the handle 40 along the Y-axis direction, because the fixing portion 45 of the handle 40 is fixedly connected to the first limiting member 50, the swing fulcrum is located between the operating portion 41 and the fixing portion 45, the first limiting member 50 has a tendency to move along the Y-axis direction, the first opening 1332 and the second opening 1372 are in an inverted U shape with a large opening at the lower end, the first clamping portion 53 has a space to move along the Y-axis, the first limiting member 50 swings along a direction opposite to the Y-axis, so that the handle 40 drives the first limiting member 50 to move along the Y-axis direction, the handle 40 can also swing along the Y-axis direction, and the movement of the first limiting member 50 drives the elastic member 70 to deform; when the external force is lost, the elastic member 70 is deformed, and the first retaining member 50 is restored to the initial position by the elastic member 70 and simultaneously drives the handle 40 to be restored to the initial position. In the process of deformation of the elastic member 70, the second limiting member 60 is also driven to move.

When an external force acts on the operating portion 41 of the handle 40 in any direction perpendicular to the Z-axis direction and other than the X-axis direction and the Y-axis direction, since the fixing portion 45 of the handle 40 is fixedly connected to the first limiting member 50, the first limiting member 50 and the handle 40 have a swing fulcrum located between the operating portion 41 and the fixing portion 45, the first limiting member 50 moves in a direction opposite to the acting direction, and the first limiting member 50 is matched with the first opening 1332, the second opening 1372 and the first gap 535, so that the first limiting member 50 has a movable space in the XY plane, and the handle 40 can swing in the acting direction. When the external force is lost, the elastic member 70 is deformed again, and the first limiting member 50 is restored to the initial position under the action of the elastic member 70 and simultaneously drives the handle 40 to be restored to the initial position. In the process of deformation of the elastic member 70, the second limiting member 60 is also driven to move.

In summary, the interaction between the first limiting member 50, the second limiting member 60, the housing 10 and the elastic member 70 enables the handle 40 to perform a 360 ° conical pendulum motion with the Z-axis as an axis.

It is understood that, in some embodiments, when the extending direction of the first limiting member 50 and the extending direction of the second limiting member 60 are at other angles, the directions of the first opening 1332, the third opening 1352, the second opening 1372 and the fourth opening 1392 on the housing 10, which are matched with the first limiting member 50 and the second limiting member 60, may also be adjusted accordingly.
