Background
The coupler is a device for connecting two shafts or connecting the shafts and a rotary member, and rotating together in the process of transmitting motion and power, and not disengaging under normal conditions. Sometimes also used as a safety device for preventing the connected parts from bearing excessive load, and playing an overload protection role.
Couplings can be divided into two main categories, rigid couplings and flexible couplings. The rigid coupling does not have the capability of buffering and compensating the relative displacement of two axes, and the two axes are required to be strictly centered, but the coupling has the advantages of simple structure, lower manufacturing cost and convenient assembly, disassembly and maintenance. Flexible couplings can be further divided into inelastic flexible couplings and flexible couplings with elastic elements, the former having only the ability to compensate for relative displacement of the two axes and the latter having cushioning and vibration damping effects. The existing coupler is complex in structure, high in production cost, more in parts and insufficient in bearable torque, and the parts are troublesome to replace after being damaged.

Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1, 2 and 3, the novel unidirectional coupling comprises a motor 1 with a motor shaft 2, a gear assembly 3 driven to rotate by the motor shaft 2, a square rib spiral spring 4 capable of being locked in a unidirectional manner and arranged between the motor shaft 2 and the gear assembly 3, a transmission shaft seat 5 in transition fit with the square rib spiral spring 4 and arranged on the motor shaft 2, and the rib spiral spring 4 is fastened on the transmission shaft seat 5 in transition fit with the gear assembly 3.
Further, the gear assembly 3 is composed of a gear 6 and a connecting piece 7, and the gear 6 is connected with the square rib spiral spring 4 through the connecting piece 7.
Further, a mounting block 8 for mounting the square-rib spiral spring 4 is arranged on the transmission shaft seat 5.
Further, the motor 1 is provided with a mounting plate 9 for mounting the motor 1, two fixing holes 10 for fixing the motor 1 are formed in the mounting plate 9, and the motor 1 can be fixed at the working position by the mounting plate 8.
Working principle: locking: the square-rib spiral spring 4 is sleeved on the transmission shaft seat 5 and the gear assembly 3, and when the motor 1 rotates in the direction consistent with the spiral direction 4 of the square-rib spiral spring, the motor shaft 2 and the gear assembly 3 are in a more-pull and more-tight state until the motor shaft 2 and the gear assembly 3 are completely locked (the gear assembly 3 and the motor 1 synchronously rotate).
And (3) disengaging: when the motor 1 rotates in the direction opposite to the direction of the square rib spring spiral 4, the square rib spring 4 is in a gradually released state, the motor shaft 2 and the gear assembly 3 are in complete disconnection linkage when the square rib spring 4 is released to a certain extent (the gear assembly 3 is disconnected from the motor 1 to lose kinetic energy at the moment), and the locking and the unlocking of the transmission direction are changed by changing the spiral direction of the square rib spring 4.
