An optical lens assembly includes, in order from a visual side to an image source side: a first lens with positive refractive power; an optical element including, in order from the visual side to the image source side, an absorptive polarizer, a reflective polarizer and a first phase retarder; a second lens with positive refractive power; a partial-reflective-partial-transmissive element; a second phase retarder; and an image source plane. The optical lens assembly has a total of two lenses with refractive power. A focal length of the optical lens assembly is f, a maximum image-source height of the optical lens assembly is INM, a focal length of the first lens is f1, a focal length of the second lens is f2, and following conditions are satisfied: 0.40<IMH/f<1.26 and 0.21<f2/f1<2.35. A head-mounted electronic device includes the optical lens assembly.

A retaining sheet is used for retaining to a slat of a venetian blind. The slat has a through hole for penetration of a lifting cord. The retaining sheet includes a main body with an upper surface, a lower surface, a hole, and a slot. The hole and the slot pass through the upper and bottom surfaces of the main body and communicate with each other. The width of the slot is smaller than the width of the hole, wherein the main body is configured when the retaining sheet is retained to the slat of the venetian blind, the hole of the main body corresponds to the through hole of the slat, and the lifting cord is penetrated through the hole and inserted into the slot when pulled by an external force. This can prevent the lifting cord from being drawn out for enhancing the safety of use.

An optical lens assembly includes, in order from a visual side to an image source side: a first group including a first lens group and an optical element, and the optical element including, in order from the visual side to the image source side: an absorptive polarizer, a reflective polarizer and a first phase retarder; a second group including, in order from the visual side to the image source side: a second lens group with positive refractive power and a partial-reflective-partial-transmissive element; and a third group including, in order from the visual side to the image source side: a second phase retarder and an image source plane. When the optical lens assembly satisfies certain conditions, the weight of the device can be reduced, the zooming function can be provided, and the image quality can be ensured.

A ladder rope retaining device includes a support base, a rotating base, and an elastic positioning member. The support base has a bottom wall and two opposite straight walls connected with the bottom wall and each having a pivot trough. The rotating base includes a pivot pivotally disposed in the pivot troughs, and a ladder rope retaining portion formed on the pivot. The pivot has a plurality of positioning recesses arranged in an equally-spaced manner. The elastic positioning member is disposed to one of the straight walls of the support base and elastically engaged with one of the positioning recesses of the pivot. Thus, when the rotating base is rotated relative to the support base, the positioning recesses are alternately engaged with and disengaged from the elastic positioning member to generate a better operating feel.

A knife rack includes a box body having a bottom, a plurality of peripheral walls surrounding the bottom, an accommodating space surrounded by the peripheral walls and the bottom and an opening provided where the accommodating space communicates with the outside, a top cover covering the opening and provided with a plurality of long slotted holes, and a plurality of round balls set within the accommodating space of the box body and used as a support structure for supporting knifes. The point-like contact between the round balls and the blades of stored knives can greatly reduce the contact area between the round balls and the blades, and the gaps between the round balls are conducive to air circulation.
