The working principle of the utility model is as follows:

referring to the attached drawings 1-4 of the specification, when the size of the printer shell needs to be detected, the printer shell is fixed, then the base 5 and the bottom surface of the printer shell are placed on the same horizontal plane, then the shell 1 is shifted, the shell 1 slides on the surface of the sliding rod 3, after the end part of the detection head 2 moves to the top position of the printer shell, the rotating wheel 6 is rotated, the rotating wheel 6 drives the main gear 7 to rotate through the connecting rod, the main gear 7 enables the secondary gear 9 to rotate in the shell 1 in a meshing mode, the main gear 7 and the secondary gear 9 are matched with the pull rope 11 through the winding roller 10 in the rotating process, the clamping frame 12 gradually approaches to the main gear 7, the clamping frame 12 is matched with the baffle 14 in the approaching process to press the first spring 15, and the clamping frame 12 is matched with the sliding rod 3 through the limiting device 13, therefore, the position of the shell 1 is limited, and further the position of the detection head 2 is limited, so that the detection head 2 can conveniently detect the size of the printer shell.

When the pull rope 11 pulls the clamping frame 12, the two clamping frames 12 are close to each other in the pulling process, the clamping frame 12 enables the convex rod 17 of the limiting device 13 to be gradually close to the sliding rod 3, when the ball 18 at the end of the convex rod 17 is attached to the surface of the sliding rod 3, the shell 1 can slide on the surface of the sliding rod 3, and the ball 18 is matched with the sliding rod 3, so that the shell 1 can slide on the surface of the sliding rod 3 through the limiting groove. The rotating wheel 6 is rotated continuously, the main gear 7 and the secondary gear 9 continue to provide pulling power for the pulling rope 11, the clamping frame 12 continues to extrude the first spring 15, at the same time, the sliding rod 3 reversely provides acting force for the convex rod 17 through the rolling ball 18, namely, the convex rod 17 gradually enters into the clamping frame 12 under the action of the reacting force, the convex rod 17 extrudes the second spring 19 through the movable plate 16, at the same time, the first rotating frame 20 and the second rotating frame 21 both rotate inside the clamping frame 12, the end part of the first rotating frame 20 slides inside the first sliding slot 22 through the clamping rod 24, the end part of the second rotating frame 21 slides inside the second sliding slot 23 through the clamping rod 24 until the side wall of the limiting slot of the clamping frame 12 clings to the surface of the sliding rod 3 after the convex rod 17 completely enters into the clamping frame 12, at the time, the pulling force of the pulling rope 11 on the clamping frame 12 causes the clamping frame 12 to be tightly attached to the sliding rod 3, thereby completing the limiting effect on the whole shell 1, thereby fixing the position of the housing 1. The rotating wheel 6 is loosened, the damping effect of the limiting sleeve 8 on the connecting rod can offset the elastic resilience of the first spring 15 and the second spring 19, so that the shell 1 is stably positioned on the surface of the sliding rod 3, and the detection of the size of the shell of the printer by the detection head 2 is facilitated. After the detection is finished, the rotating wheel 6 is rotated reversely, and the elastic forces of the first spring 15 and the second spring 19 enable the clamping frame 12 and the limiting device 13 to gradually restore the original state, so that the shell 1 can continue to slide on the surface of the sliding rod 3 until the next detection.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
