In this way, the stop lever 93 is prevented from being damaged by violent contact with the frame 1, which would affect the use.
Initially, the second magnet 1103 repels the first magnet 1102, when the first push plate 66 moves leftwards, the first push plate 66 moves leftwards to drive the scale sleeve 1101 to move leftwards, the scale sleeve 1101 moves leftwards to drive the first magnet 1102 to move leftwards, and then the first push plate 66 moves leftwards to compress the second spring 68, and when the first magnet 1102 is limited by the guide rod 69, the first push plate 66 also continues to move leftwards through the second spring 68 to drive the second push plate 67 to drive an object in the trackless chassis 21 to move leftwards, so that an operator can know how much force is used by looking at the force data on the scale sleeve 1101 indicated by the first magnet 1102, and then the object on the trackless chassis 21 can slide. When the first push plate 66 moves to the right for resetting, the first push plate 66 drives the first magnet 1102 to move to the right for resetting through the scale sleeve 1101, and the first magnet 1102 and the second magnet 1103 continuously repel each other, so that the first magnet 1102 can be prevented from moving to the right beyond a maximum distance. Therefore, people can know how much force is used more clearly.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
