When the number of files or books stored is small, the files or books will be tilted and slipped, causing the files or books to be deformed; When the number of files or books is small, part of the space on the desktop is wasted; there are two types of bookends, one is composed of two independent sides, the two sides can move freely, and the distance is not fixed, because the independent sides on both sides are not fixed, it is easy to Separated, files or books topple over; another kind of bookend is fixed on one side, and the other side can move freely. The length of the bookend is fixed. Bookends are toppled over, but because the length of the bookends is fixed, desktop space is wasted, and the bookends have less functions at present, and new technologies are needed to make up for this deficiency.

Utility model content:

The purpose of the present utility model is to provide a multifunctional retractable bookend in order to solve the above problems, and to provide a multifunctional bookend that can be adjusted freely.

In order to solve the above problems, the utility model provides a technical solution: a multifunctional retractable bookend, including a base, a universal wheel, a first vertical rod, a second vertical rod, a horizontal rod, a hook, a pen holder, Pen holder, third vertical rod, left connecting plate, right connecting plate, spring, telescopic rod and triangular ruler; the lower end of the base is provided with several universal wheels; the center position of the upper surface of the base is fixedly connected with a second vertical rod; the right end of the upper surface of the base is fixedly connected with a first vertical rod; a horizontal rod is fixedly connected between the first vertical rod and the second vertical rod; the lower end of the horizontal rod is fixedly connected with several hooks; A pen rest is provided below the cross bar, and the pen rest is fixedly connected to the base; a pen container is fixedly connected to the outer surface of the first vertical bar; a pen holder is slidably connected to the left side of the upper surface of the base The third vertical bar; the left side of the third vertical bar is connected with a triangle ruler; the upper end of the right side of the third vertical bar is fixedly connected with a left connecting plate; the right connecting plate is slidably connected in the left connecting plate, The right side of the right connecting plate is fixedly connected to the second vertical bar, a spring is arranged between the right connecting plate and the third vertical bar; a spring is also connected between the third vertical bar and the second vertical bar. A telescoping pole.

Preferably, the spring is a disc spring.

Preferably, an anti-slip device is provided on the universal wheel.

Beneficial effects of the utility model: its structure design is reasonable, the shape is novel and unique, and the overall structure is simple. A telescopic connecting plate is arranged between the vertical bars, and the vertical bars are connected together through the telescopic connecting plate. At the same time, springs are used to Realize the automatic expansion and contraction of connecting plate, thus realize the automatic expansion and contraction of vertical bar, also set hook, pen container and pen holder to place pen, also set triangle ruler for measuring, realize multi-purpose.
