Problems solved by technology
This kind of book stand uses the stretching of the spring and the solid plate to protrude from the hollow groove to place more books, so it takes a long time to place more books, and when you want to place a few more books, the spring will be stretched and shrink The problem of not going back, affecting the use

Embodiment
[0029] Such as figure 1 As shown, a telescopic book end includes two vertical boards 1, and the two vertical boards 1 are arranged opposite to each other. A pair of telescopic rods 2 are connected to the bottom of the opposite side, and the bottom edge of the vertical board 1 is connected to the side of the telescopic rod 2. The sides are connected at right angles, and a pair of telescopic rods 2 connected to each vertical board 1 are distributed on both sides of the bottom of the vertical board 1. The telescopic rods 2 are composed of multi-stage rods. The first-stage rod at the front end is detachably fixed together with the front-end first-stage rod on the opposite telescopic rod 2 on the corresponding other vertical plate 1, and the side of each stage rod is worn except the first-stage rod at the front end. An adjusting screw 3 is provided, and the adjusting screw 3 runs through the side wall of each level of rod, and can be screwed in and out relative to the side wall, so...

The invention discloses a telescopic book end comprising two vertical plates. A pair of telescopic rods is connected to the bottom of one side of each of the two vertical plates. The bottom side of each vertical plate is in right angle connection with the side of the corresponding telescopic rod, and the pair of telescopic rods connected by each vertical plate is distributed on two sides of the bottom of the vertical plate. The telescopic rods are composed of multi-stage rods. First-stage rods at the front ends of the opposite telescopic rods of the opposite vertical plates are detachably fixed together. Except the first-stage rods at the front ends, an adjusting screw is arranged on the side of each stage of the rods respectively for adjusting the stretching length of the next-stage rod inserted in the current-stage rod. The telescopic book end solves the problem of no resetting in case of spring looseness, and has good adjusting telescopic performance. The pair of telescopic rods isarranged at the bottom of each vertical plate, so that better stability can be achieved compared with the mode of one telescopic rod in the middle.
Description
technical field [0001] The invention relates to the technical field of office supplies, more specifically, it relates to a retractable book end. Background technique [0002] Bookends are items used to support books to stand stably. They are mostly made of iron, stainless steel and other materials in an "L" shape and appear in pairs. Bookends keep a row of standing books from tipping over to prevent books from being cornered, bent or damaged. Bookends can also be used to organize different types of books. Libraries often use bookends to organize bookshelves with gaps, and companies and individuals can also use bookends to open up neat space for books and materials on flat desks. [0003] The two vertical boards of the ordinary book end are designed separately, and the width between the two vertical boards can be adjusted according to the number of books stored. Since the vertical boards are designed independently, the book end is not strong enough to place the books, and i...
