Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 and 2, the width freely-adjustable english teaching tool includes an outer hinge shaft, a first support arm, a second support arm, a third support arm and a fourth support arm, wherein front ends of the first support arm, the second support arm, the third support arm and the fourth support arm are respectively provided with a working cavity, and rear ends of the first support arm, the second support arm, the third support arm and the fourth support arm are respectively hinged on the outer hinge shaft; an elastic painting brush device is arranged in the working cavity. The elastic painting brush device comprises a supporting spring, a clamping block, a clamping arm and a clamping jaw, a through hole is formed in the working cavity, the clamping block is arranged at one end, penetrating into the through hole, of the clamping arm, and the clamping jaw is arranged at one end, penetrating out of the through hole, of the clamping arm and extending out of the working cavity; the clamping claw is clamped with a painting brush; one end of the supporting spring is connected with the clamping block, and the other end of the supporting spring is connected with the inner wall of the working cavity. Wherein one side of the first support arm, the second support arm, the third support arm and the fourth support arm is provided with an operation arm; the first control strip hole, the second control strip hole, the third control strip hole and the fourth control strip hole are respectively arranged in the first support arm, the second support arm, the third support arm and the fourth support arm, and the first connecting arm, the second connecting arm, the third connecting arm and the fourth connecting arm are respectively arranged on the operating arm; the first connecting arm, the second connecting arm, the third connecting arm and the fourth connecting arm are respectively provided with a first rolling shaft, a second rolling shaft, a third rolling shaft and a fourth rolling shaft; the first roller, the second roller, the third roller and the fourth roller are respectively provided with a first roller, a second roller, a third roller and a fourth roller; the first roller, the second roller, the third roller and the fourth roller are respectively provided with a first groove, a second groove, a third groove and a fourth groove; the first groove, the second groove, the third groove and the fourth groove are respectively clamped at two sides of the first control strip hole, the second control strip hole, the third control strip hole and the fourth control strip hole.
