[0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The motor is represented by the letter M (D in the old standard) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy.

[0003] The prior art refers to an automatically adjustable longitudinal motor structure disclosed in the announcement number CN210839215U. This design enables the telescopic rod to telescope left and right in the telescopic seat to adjust the length of the telescopic rod. Because a spring is installed on the lower side of the positioning pin, positioning grooves are provided on the upper and lower sides of the telescopic rod, and the positioning grooves match the positioning pin. This design facilitates the telescopic rod to telescope left and right while achieving a good positioning effect on the telescopic rod.

[0004] However, in the prior art, the connecting rod and the telescopic seat are connected by a nut and a threaded head. When driven by the motor body, the connecting rod and the telescopic seat will be subjected to the reaction force of the driving end connecting component, which will cause the threaded head and the telescopic seat to slide against each other, posing a safety hazard. In addition, the matching stability of the positioning pin and the positioning slot on the telescopic rod is poor, and it is difficult to fix the telescopic rod after the length is adjusted. For this reason, we have designed an automatically adjustable longitudinal motor structure. Utility Model Content
