The sliding guide mechanism includes a slot step 220 arranged on the two lateral sides of the mounting foot 22. The slot step 220 is connected with the base 21. The slot step 220 is sequentially connected with a positioning groove 221 recessed on the lateral side wall of the mounting foot 22. The middle part of the two inner walls of the slot 11 is protruded with a guide convex rail 31, that is, the guide convex rail 31 is at a certain distance from the mouth 11a of the slot 11, and the guide convex rail 31 is inserted into the positioning groove 221 one by one. Figure 1 and 3 As shown, a plurality of limited fits are formed between the mounting foot and the first pile head member 1, so that the mounting foot can slide on the first pile head member 1 more stably and reliably, thereby avoiding shaking of the second pile head member when the second pile head member slides on the first pile head member 1 to adjust the position, thereby improving the adjustment accuracy.

[0029] As an embodiment of the present invention, the two guide convex rails 31 are connected via a connecting portion 32 to form a guide rail component 3, and the guide rail component 3 is fixedly installed in the slot 11. The two guide convex rails are independently processed accessories, which are assembled into the slot 11 after processing, which is convenient for processing and installation; of course, as another feasible solution of the present invention, the guide convex rail can be directly integrally formed on the inner wall of the slot; but there is a defect of inconvenient processing. The connection between the two guide convex rails 31 can be a detachable connection, such as a convex point and a concave point interlocking, or an integrally formed connection in this specific embodiment; those skilled in the art can use existing conventional technology to install the guide rail component into the slot.

[0030] Further, such as Figure 6As shown, one end of the two guide convex rails 31 on the guide rail member 3 in the length direction is integrally connected by a connecting portion 32, so that the guide rail member 3 is in a U-shape with one end open; to facilitate the installation of the guide rail member 3, the first pile head member 1 includes two mounting plates 1-1 arranged oppositely and connected to each other, the interval between the two mounting plates 1-1 constitutes the slot 11, at least one lateral side of the slot 11 is a through opening, the guide rail member 3 is clamped and fixed in the slot 11 by the two mounting plates 1-1, and the opening of the guide rail member 3 corresponds to the through opening of the slot 11 so that the mounting foot 22 can be slidably inserted into the slot 11. During installation, a single guide rail member 3 is clamped and fixed by the two mounting plates 1-1, the guide rail member 3 is conveniently and reliably processed and molded and installed, the first pile head member 1 can be inserted into and withdrawn from the slot 11 along its sliding direction, and the first pile head member 1 is easy to install.

[0031] A snap-on protrusion 33 is protruded from the back of the two guide convex rails 31, and a snap-on hole 12 is provided on the two mounting plates 1-1, and the snap-on protrusion 33 is inserted into the snap-on hole 12. The back of the guide convex rail 31 and the mounting plate adopt a concave-convex plug-in to achieve the positioning and installation of the guide component, which has the advantages of simple and convenient installation and high assembly efficiency. At least two spaced snap-on protrusions 33 are provided on the back of each guide convex rail 31, and correspondingly at least two snap-on holes 12 are provided on an inner side wall of the slot 11, and the snap-on protrusions 33 and the snap-on holes 12 are matched one by one. In addition, a positioning shallow groove 13 is provided on the inner wall of the slot 11, and the snap-on hole 12 is located in the positioning shallow groove 13, and the back part of the guide convex rail 31 is embedded in the positioning shallow groove 13 to achieve positioning. A more reliable fixed installation of the U-shaped member 3 is achieved, and the installation accuracy is high.

[0032] The spacing between the two mounting plates 1-1 is adjustable to adjust the clamping force of the guide rail member 3. The U-shaped design of the guide rail member 3 allows the guide rail member 3 to have a certain elastic deformability, that is, to fine-tune the spacing between the two guide convex rails 31 of the guide rail member 3 and the matching clearance between the mounting feet 22 of the guide rail member 3, so that the mounting feet 22 are installed more stably and reliably to avoid shaking. The spacing between the two mounting plates 1-1 is adjusted by screws used to connect and lock the two mounting plates. The positioning adjustment mechanism includes a linkage gear 52, a linkage gear shaft 50, a rack 51 and a locking member 4. The linkage gear 52 is rotatably installed in the slot 11 via the linkage gear shaft 50. The rack 51 is arranged at the bottom of the mounting foot 22. The linkage gear 52 meshes with the rack 51. The linkage gear shaft 50 is a screw for locking the two mounting plates. In this way, a simpler and more compact installation arrangement is achieved. The spacing between the two guide convex rails of the first pile head member is controlled by the locking force of the linkage gear shaft, driving the guide rail member 3 to deform and achieve adjustment. The locking member is preferably used in conjunction with the linkage gear. The locking member 4 includes a swing arm 41 hinged at one end on the first pile head member 1. The swing end of the swing arm 41 is provided with a latching tooth 42. The locking member 4 is locked and unlocked with the linkage gear 52 via the latching tooth 42. The state of the locking member 4 is maintained by the damping force. One method is to install the locking member 4 at the rotation fulcrum with a screw, and control the damping force by adjusting the locking force of the screw, or / and the second structural design: when the locking member is in the locked state, the swing arm 41 is at least partially buckled into the slot 11, and the swing arm 41 is clamped by the two walls of the slot 11. During the adjustment operation, the locking member is pulled, and the locking teeth of the locking member disengage the linkage gear 52, and the linkage gear 52 can rotate, pulling the second pile head member to slide for position adjustment. After the position adjustment is completed, the locking member is pulled, and the locking teeth of the locking member engage the linkage gear 52, and the linkage gear 52 is locked, so that the second pile head member is locked through the rack meshed therewith, and the position locking of the temple is achieved. The structure is simple and convenient.

[0033] In this specific embodiment, the connection between the two mounting plates 1-1 is locked by screws, and a clamp 1-11 is provided at the bottom of the mounting plate 1-1, and a socket is provided on the lens ring. The clamp 1-11 is inserted into the socket and clamped on the edge of the socket to achieve the installation of the mounting plate 1-11 on the lens ring and the mutual connection between the two mounting plates. Of course, as those skilled in the art can easily think of, the mutual connection between the two mounting plates can also be achieved by using an integrally formed connecting plate, or by using other connecting structures such as buckles or welding.

[0034] like Figures 8 to 11 , Figure 2 , Figure 4 and Figure 6As shown, another embodiment provided by the utility model is Figures 1 to 7 The difference between the embodiments shown mainly lies in the different designs of the positioning and adjusting mechanisms, specifically:

[0035] The positioning adjustment mechanism includes a linkage gear 52, a linkage gear shaft 50, a rack 51, a stabilizing gear 53 and a stabilizing gear shaft. The linkage gear 52 is rotatably installed in the slot 11 via the linkage gear shaft 50. The rack 51 is arranged at the bottom of the mounting foot 22. The linkage gear 52 is meshed with the rack 51.

One end of the linkage gear 52 shaft is provided with an operating end 54 for operating the linkage gear 52 to rotate. The operating end 54 can be a hand-tightening knob, wherein the operating end 54 is a hand-tightening knob; direct manual adjustment operation is realized, and the adjustment operation is simpler without the aid of tools. Therefore, it can also be adjusted by using a screwdriver, and the shaft end of the linkage gear is a screw head structure design; the positioning adjustment mechanism also has a locking member 4 for locking and unlocking the second pile head member. The linkage gear 52 is also provided with a stabilizing gear 53, which can reduce the starting speed of the linkage gear 52 during the rotation operation, improve the feel of the adjustment operation, and further improve the accuracy of the adjustment operation. After the position adjustment is completed, the second pile head member 2 is locked by the locking member 4. The locking member 4 can act on the linkage gear, the stabilizing gear or the rack. The locking member 4 includes a swing arm 41 with one end hinged on the first pile head member 1. The swing end of the swing arm 41 is provided with a latching tooth 42. The locking member 4 is locked and unlocked with the linkage gear 52 through the latching tooth 42. The state of the locking member 4 is maintained by the damping force. One method is to install the locking member 4 at the rotation fulcrum by a screw, and control the damping force by adjusting the locking force of the screw, or / and the second structural design: when the locking member is in the locked state, the swing arm 41 is at least partially buckled into the slot 11, and the swing arm 41 is clamped by the two walls of the slot 11 to achieve the effect.
