When the mechanism is used, two ends of the lamp tube are respectively placed in the supporting grooves of the supporting seat and the second supporting seat, then the linear driving mechanism is started to enable the checking block to tightly press the end part of the lamp tube, so that the axial end face of the lamp tube side is in contact with the detecting block, so that the axial end face of the other end of the lamp tube is in contact with the groove wall of the second supporting seat, then the second linear driving mechanism drives the end of the positioning block, if the positioning block can extend into the positioning groove, the length of the lamp tube is up to standard, and if the positioning block cannot extend into the positioning groove, the length of the lamp tube is not up to standard.

Preferably, the tolerance range of the lamp tube length is ± L1, the length of the positioning slot is L2, and the length of the lower end of the positioning block along the front-rear direction is L3, wherein L2 > L3, and L2+ L3 is L1X 2.

Preferably, the th supporting seat has a second guide groove opening to the second linear driving mechanism side and communicating with the th guide groove, the positioning block is always positioned in the second guide groove, and the second guide groove is used for limiting the forward and backward swinging of the positioning block, so that the detection accuracy of the present invention is more accurate.

Preferably, the outer edge of the cross section of the positioning block along the front-back direction is circular. The distance between the front direction and the rear direction of the positioning block is inconvenient when the positioning block rotates, so that the detection precision of the invention is more accurate.

Preferably, the detection block is recessed towards the end face of the second support seat to form an annular groove for avoiding the lamp tube pins.

Preferably, the second supporting seat is composed of an inner section and an outer section, the inner section is provided with the supporting groove, the outer section is provided with an upward opening yielding groove, and the width of the yielding groove in the left-right direction is smaller than that of the supporting groove in the left-right direction.

Preferably, at least side of the contact surface of the guide groove and the detection block is a plane, so that the detection block is prevented from rotating when moving forwards and backwards, and the alignment of the positioning groove and the positioning block is ensured.

The th supporting seat and the second supporting seat are preferably arranged on the guide rails arranged along the front-back direction, so that the invention can be used for detecting whether the lengths of the lamp tubes with different lengths are qualified or not.

Preferably, the th supporting seat and second supporting seat all are equipped with the screw hole and cooperate and have fastening bolt, and fastening bolt rotates in order to offset with the guide rail.

The invention has the advantages of being capable of being used for detecting whether the length of the lamp tube is qualified or not and detecting the lengths of a plurality of lamp tubes for times.
