Further, referring to fig. 6, a bar-shaped hole is further formed in the second casing 151, a scale bar 154 is disposed at the bar-shaped hole, a pointer 145 matched with the bar-shaped hole is correspondingly disposed on the guide bar casing 140, and the pointer 145 is used for indicating an actual moving distance between the protection casing 150 and the guide bar casing 140, that is, a lifting height of the stopper 600.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features. The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
