Abstract

The utility model relates to a law teaching tool, particularly to a book supporting device for law teaching. A book clamping device for the law teaching aims at solving the problems that teachers need to read textbooks and teach in class simultaneously and need to open the textbooks again due to the fact that the textbooks are automatically closed sometimes. The book clamping device comprises a book supporting plate and a reversed U-shaped compression bar, wherein the upper end face of the book supporting plate is provided with a long trapezoidal groove along the center; the upper end face of the book supporting plate is also provided with two reversed T-shaped sliding grooves which are parallel to the long trapezoidal groove; the two reversed T-shaped sliding grooves are symmetrically formed in the bilateral sides of the long trapezoidal groove; T-shaped sliding blocks which are matched with the two reversed T-shaped sliding grooves are arranged at two ends of the reversed U-shaped compression bar respectively; the two ends of the reversed U-shaped compression bar are arranged inside the two reversed T-shaped sliding grooves respectively; and the T-shaped sliding blocks are connected with the two reversed T-shaped sliding grooves in a sliding mode. The book clamping device for the law teaching is used for the law teaching.

Description

A kind of book clamping machine of science of law teaching usefulness

Technical field

The utility model relates to a kind of science of law teaching aid, is specifically related to a kind of bookshelf device of science of law teaching usefulness.

Background technology

In science of law teaching process, the teacher needs the limit to read in the classroom to teach the explanation of book limit, when translating into the lecture contents part, need pin the desired page of books with hand, sometimes need write at blackboard, at this moment hand leaves the book of teaching, and the gathering of calligraphers of teaching is closed automatically, when needs are read when teaching the book desired page again, to turn over book again, therefore, make troubles to teachers' instruction, wasted the finite time in classroom.

The utility model content

The purpose of this utility model is in order to solve in science of law teaching process, and the teacher needs the limit to read in the classroom to teach the explanation of book limit, and the gathering of calligraphers of teaching is sometimes closed automatically, need turn over the problem of book again, and a kind of book clamping machine of science of law teaching usefulness is provided.

Book clamping machine of the present utility model comprises book supporting board and inverted U-shaped depression bar, the upper surface of described book supporting board is provided with trapezoidal long recess along the center, the upper surface of described book supporting board is provided with two inverted T-shaped chutes that be arranged in parallel with trapezoidal long recess, two inverted T-shaped chutes are symmetricly set on the both sides of trapezoidal long recess, the two ends of inverted U-shaped depression bar are equipped with the T shape slide block that matches with the inverted T-shaped chute, the two ends of inverted U-shaped depression bar are separately positioned in two inverted T-shaped chutes, and T shape slide block and T shape chute are slidingly connected.

The utility model has the advantages that: one, utilize the utility model the desired page of the book of teaching can be pushed down, the feasible book of teaching can not close automatically, need not to pin with hand the page of books, has made things convenient for teachers' instruction, save turning over the book time of classroom, improved efficiency of teaching.Two, can adjust the upper-lower position of inverted U-shaped depression bar by the inverted T-shaped chute, it is capable to avoid inverted U-shaped depression bar to block word.
