Specifically, the driving structure 2 includes a driving gear 21 rotatably disposed on the mounting portion 11, and the abutting portion 12 is provided with a tooth portion 121 engaged with the driving gear 21. The structure for driving the abutting portion 12 to move by the driving structure 2 may be a linear driving structure, such as an air cylinder driving push rod, or may be a rotational driving member, such as a cam structure driving push rod, which is not limited herein, and it is sufficient that the driving structure 2 drives the abutting portion 12 to extend and retract relative to the mounting portion 11. In this embodiment, the driving structure 2 is set to the driving gear 21, the abutting portion 12 is provided with a tooth-shaped portion 121 corresponding to the driving gear 21, the driving gear 21 rotates to push the abutting portion 12 to move linearly so as to extend out the installation portion 11 or contract to the installation portion 11, on one hand, the driving gear 21 is stable in cooperation with the tooth-shaped portion 121, and the slippage dislocation cannot occur, so that the adjustment effect is stable, on the other hand, the driving gear 21 is provided with a tooth portion on the tooth-shaped portion 121, and the driving gear 21 is in positioning fit with the tooth-shaped portion 121, so that the setting position of the stopping structure 3 can be not limited, and only the driving gear 21 needs to extend into the tooth portion of any one of the tooth-shaped portions 121 to complete the stopping operation, so that the design freedom cost is low, the setting of the stopping structure 3 is convenient, and the abutting portion 12 is not needed to be provided with the driving gear 21 to be provided with an additional stopping portion for the stopping structure 3 to cooperate, thereby reducing the design of the structural characteristics and reducing the cost.
Specifically, the stopping structure 3 includes a first stopping portion 311 movably disposed, the first stopping portion 311 has a locking position and an unlocking position on a movable stroke thereof, and in the locking position, the first stopping portion 311 is engaged with the driving gear 21 to at least limit the driving gear 21 to rotate in a direction of driving the abutting portion 12 to retract to the mounting portion 11. Adopt backstop structure 3 cooperation drive gear 21's mode, if be in when backstop structure 3 backstop, drive gear 21 applys drive power, backstop structure 3 atress backstop and can not applyed drive power extremely profile of tooth portion 121 avoids drive gear 21 with receive the force between the profile of tooth portion 121 and damage, increase of service life. The first stopping portion 311 may release the locking state of the abutting portion 12 in a manner of moving along with the movement of the abutting portion 12, for example, the first stopping portion 311 is also configured to be a rotatable structure so as to be rotationally engaged with the driving gear 21, the rotatable structure is self-locked to limit the rotation of the driving gear 21 in the locking state, and the rotatable structure rotates along with the driving gear 21 in the unlocking state without limiting the driving gear 21 to drive the abutting portion 12 to move.

Further, the stopping structure 3 further includes a second stopping portion 312 located on one side of the first stopping portion 311 in the axial direction of the driving gear 21, and the second stopping portion 312 is movably disposed, so that a locking position and an unlocking position are provided on a movable stroke of the second stopping portion 312; the driving gear 21 can be movably arranged along the axial direction thereof, so that the driving gear has a first position engaging with the first stopping portion 311 and a second position engaging with the second stopping portion 312; the first stopping portion 311 engages with the driving gear 21 to limit the driving gear from rotating in a direction of driving the abutting portion 12 to retract to the mounting portion 11, and the second stopping portion 312 engages with the driving gear 21 to limit the driving gear from rotating in a direction of driving the abutting portion 12 to extend out of the mounting portion 11. In this embodiment, in order to facilitate the adjusting operation of the glasses 1000, the first stopping portion 311 is set to only stop the rotation of the driving gear 21 to avoid the retraction of the abutting portion 12, so that when the driving gear 21 is engaged with the first stopping portion 311, the driving gear 21 can also rotate in a reverse direction to push the first stopping portion 311 to an unlocking position, and further drive the abutting portion 12 to extend out of the mounting portion 11, that is, similar to a ratchet structure, specifically, the rotation of the driving gear 21 is limited in a single direction, so that the first stopping portion 311 does not need to be operated additionally to move and the driving gear 21 does not need to be operated to stagger the first stopping portion 311, the state where the first stopping portion 311 is engaged with the driving gear 21 is maintained, and the glasses legs can also adjust the distance between the glasses 1000 and 200 to be small, and do not bounce, facilitate the adjusting operation and facilitate the use of the glasses 1000. On this basis, if when the space between the temple bars 200 is too small to cause the wearer to be uncomfortable, the driving gear 21 needs to be staggered with the first stopping portion 311, or the first stopping portion 311 is operated to move to the unlocking position, so that the driving gear 21 can drive the abutting portion 12 to move back to the mounting portion 11 to expand the space between the temple bars 200, in this embodiment, the driving gear 21 is movably arranged to stagger the first stopping portion 311, so as to achieve the expanded adjustment of the space between the temple bars 200, and obviously, compared with a mode of operating the first stopping portion 311 to move to the unlocking position and then operating the driving gear 21 to drive the abutting portion 12 to adjust, the mode of directly operating the driving gear 21 to adjust after the driving gear 21 is staggered with the first stopping portion 311 is simple and convenient, and the operation part does not need to be switched. In addition, for the foolproof treatment, the second stopping portion 312 is disposed on one side of the first stopping portion 311, when the driving gear 21 moves to the second position and is staggered with respect to the first stopping portion 311, the driving gear 21 is meshed with the second stopping portion 312, based on the same principle as the first stopping portion 311, when the driving gear 21 is meshed with the second stopping portion 312, the abutting portion 12 can only be driven to retreat to the mounting portion 11 to increase the distance between the temples 200, and when the abutting portion 12 needs to be extended out of the mounting portion 11 to decrease the distance between the temples 200, the driving gear 21 needs to be restored to the first position and meshed with the first stopping portion 311.
Specifically, the stopping structure 3 includes a stopping block 31 and a first elastic element 32, the stopping block 31 is movable along the radial direction of the driving gear 21, and one end of the stopping block 31 is provided with the first stopping portion 311 and the second stopping portion 312; the first elastic element 32 abuts between the stop block 31 and the mounting portion 11. In this embodiment, the first stopping portion 311 and the second stopping portion 312 are integrally disposed, that is, disposed on the stopping block 31 and driven by the first elastic member 32, so as to simplify the structure and reduce the cost, and on the other hand, when the driving gear 21 operates between the first position and the second position, the driving gear 21 may rotate in a staggered manner with the first stopping portion 311 or the second stopping portion 312, and the first stopping portion 311 and the second stopping portion 312 are integrally disposed, so that the two portions are relatively stationary, when the driving gear 21 successfully meshes with one of the first stopping portion and the second stopping portion, the driving gear 21 may be smoothly meshed with the other one of the first stopping portion 311 and the second stopping portion 312, and the problem that the teeth of the driving gear 21 are interfered with the first stopping portion 311 or the second stopping portion 312 due to circumferential misalignment of the driving gear 21, so as to affect the axial movement of the driving gear 21, may not occur.
Further, two sides of the first stopping portion 311 along the tangential direction of the driving gear 21 are set as a first slope surface 311a on one side and a first stopping surface 311b on the other side; the second stopping portion 312 is provided with a second slope surface 312a and a second stopping surface 312b along two sides of the tangential direction of the driving gear 21, which are opposite to the first stopping portion 311; the first stop surface 311b and the second stop surface 312b limit the rotation of the driving gear 21 along one direction, so as to limit the abutting portion 12 to retract to the mounting portion 11 or extend out of the mounting portion 11.
