[0037] Currently, connecting two optical devices typically requires an adapter structure. Existing adapter structures fail to automatically lock during the connection process, are cumbersome, and are inconvenient to operate. Furthermore, the adapter structure is closed during the connection, preventing light from passing through. Therefore, when the two optical devices are used in series, they are blocked from light, making them inadequate for use.

[0038] The utility model provides a switching structure that solves the above problem.

[0039] In one embodiment, the adapter structure is provided with a clamp 10, a rotating ring 20 and a clamping ring 30 in sequence along its axial direction, wherein the clamp 10 is used to clamp the objective lens side of an optical device; the rotating ring 20 is sleeved on the clamp 10, and the rotating ring 20 can rotate between a first position and a second position along the circumference of the clamp 10, and the rotating ring 20 and the clamp 10 are connected by a reset assembly 40; the clamp 10 is provided with a locking assembly 50, and the locking assembly 50 is used to lock the rotating ring 20 when the rotating ring 20 is rotated to the second position; the clamping ring 30 is used to clamp the eyepiece side of another optical device; the clamping ring 30 can extend into the rotating ring 20 when the rotating ring 20 is in the second position, and push the locking component 50 to unlock the rotating ring 20, so that the rotating ring 20 can be rotated from the second position to the first position by pulling the reset component 40. The rotating ring 20 rotated to the first position is locked with the clamping ring 10 and the clamping ring 30 on both sides along the axial direction, and the clamping ring 10, the rotating ring 20 and the clamping ring 30 are connected in sequence to form a light channel 60 connecting the objective lens side and the eyepiece side.

[0040] like Figures 1 to 5As shown, the axial direction of the adapter structure is the front-to-back direction, with the clamp 10, swivel 20, and collar 30 arranged in order from front to back. When two optical devices need to be connected, the swivel 20 is placed on the clamp 10. The swivel 20 is connected to the clamp 10 via the reset assembly 40 and rotates along the circumference of the clamp 10 between a first position and a second position. Figure 1 、 Figure 2 and Figure 4 The swivel 20 is shown in the second position. The first position is Figure 4 The position of the swivel 20 after rotating clockwise, Figure 3 The swivel 20 is shown in the first position. The clamp 10 of this embodiment is a cylindrical structure, and the swivel 20 and the clamping ring 30 are both annular structures to facilitate assembly.

[0041] When the swivel 20, which is mounted on the clamp 10, is rotated counterclockwise to the second position, the locking assembly 50 on the clamp 10 locks the swivel 20, causing the swivel 20 to pause in the second position and prevent further rotation. With the swivel 20 locked, the clamp 10 secures the objective lens side of an optical device.

[0042] The retaining ring 30 is then inserted into the swivel 20. The retaining ring 30 pushes the locking assembly 50 to unlock the swivel 20, allowing the swivel 20 to quickly rotate from the second clockwise position to the first position by pulling the reset assembly 40. When rotating to the first position, the swivel 20 is locked to the clamp 10 and the retaining ring 30 on both sides of the axial direction, i.e., the front and rear sides of the swivel 20. Under the action of the reset assembly 40, the swivel 20 is quickly and automatically locked with the clamp 10 and the retaining ring 30. This achieves rapid assembly while also realizing an automatic locking function, ensuring the assembly stability of the adapter structure. Furthermore, the assembly of the clamp 10, swivel 20, and retaining ring 30 can be completed by rotating the swivel 20, making the operation quick and simple. The retaining ring 30 can then clamp the eyepiece side of another optical device, thereby connecting the two optical devices through the adapter structure.

[0043] After assembly, the clamp 10, the rotating ring 20 and the clamping ring 30 are connected in sequence to form a light channel 60. The light channel 60 connects the objective side with the eyepiece side. There is no obstruction between the eyepiece side and the objective side, realizing the serial use of the two optical settings, so that the optical equipment on the objective side can observe the display screen on the eyepiece side through the light channel 60, meeting the usage requirements.

[0044] It is understandable that the adapter structure of the present invention can realize quick assembly and quick disassembly, which is quick, convenient and easy to operate. The disassembly process is the opposite of the assembly process, which will not be described in detail here.

[0045] In one embodiment, a mounting groove 111 is axially provided on one side of the clamp 10 facing the swivel 20, and the locking assembly 50 includes a locking rod 51 and a first elastic member 52. The first elastic member 52 is axially arranged in the mounting groove 111, and the locking rod 51 is connected to the first elastic member 52. A locking plate ring 21 is circumferentially provided in the swivel 20, and a locking hole 22 is provided in the locking plate ring 21. The first elastic member 52 is used to push the locking rod 51 into the locking hole 22 to lock the swivel 20 when the swivel 20 is in the second position, and the retaining ring 30 can push the locking rod 51 in the opposite direction to disengage the locking hole 22 when the swivel 20 is in the second position to unlock the swivel 20.

[0046] like Figure 1 As shown, the rear side of the clamp 10 is provided with a mounting slot 111 along the front-to-back direction. The locking assembly 50 includes a locking rod 51 and a first elastic member 52. The first elastic member 52 is disposed within the mounting slot 111 along the front-to-back direction, and the locking rod 51 is connected to the rear end of the first elastic member 52. A locking plate ring 21 is disposed circumferentially within the swivel 20, and the locking plate has a locking hole 22. During assembly, when the swivel 20 is sleeved onto the clamp 10 and rotated relative to the clamp 10 to the second position, the locking hole 22 is aligned with the locking rod 51. The first elastic member 52 then pushes the locking rod 51 backward into the locking hole 22, locking the locking plate ring 21 in the second position and thereby pausing the swivel 20 in the second position. Then the clamping ring 30 is extended forward from the rear side of the swivel 20 into the swivel 20, and the front side of the clamping ring 30 is pushed in the opposite direction, that is, the locking rod 51 is pushed forward to disengage the locking rod 51 from the locking hole 22, thereby unlocking the swivel 20. The unlocked swivel 20 is rotated from the second position to the first position under the pull of the reset assembly 40, so as to be quickly and automatically locked with the clamp 10 and the clamping ring 30.

[0047] The transfer structure can lock the swivel 20 by cooperating with the locking rod 51, the first elastic member 52 and the locking hole 22, and can unlock the swivel by pushing the locking rod 51 with the clamping ring 30 during the assembly of the clamping ring 30 into the swivel 20. The structural design is ingenious, and the assembly and disassembly is quick and convenient, and easy to operate.

[0048] In one embodiment, a mounting flange 11 is formed on the side of the clamp 10 facing the swivel 20, and a mounting groove 111 is formed on the mounting flange 11. The mounting flange 11 is away from the end face of the clamp 10 to form an open side 112 of the mounting groove 111; when the swivel 20 is in the second position, the locking rod 51 corresponds to the position of the locking hole 22, so that it extends out of the open side 112 and is inserted into the locking hole 22 under the push of the first elastic member 52, or is disengaged from the locking hole 22 and retracted into the mounting groove 111 under the reverse push of the clamp 30; the locking plate ring 21 abuts against the end face, and blocks the locking rod 51 when the position of the locking hole 22 is staggered with the locking rod 51, so as to limit the locking rod 51 in the mounting groove 111.

[0049] like Figure 1 and Figure 3As shown, a mounting flange 11 is formed on the rear side of the clamp 10, and the mounting flange 11 is arranged to protrude rearward. A mounting groove 111 is formed on the mounting flange 11. The end surface of the mounting flange 11 facing away from the clamp 10, that is, the rear end surface of the mounting flange 11 forms the opening side 112 of the mounting groove 111. When the swivel 20 is in the second position, the locking rod 51 corresponds to the position of the locking hole 22, and is specifically arranged to face each other, so that the locking rod 51, pushed by the first elastic member 52, extends backward from the opening side 112 and inserts into the locking hole 22, thereby locking the swivel 20. When the clamping ring 30 extends forward into the swivel 20, the clamping ring 30 pushes the locking rod 51 forward, causing the locking rod 51 to disengage from the locking hole 22 and retract into the mounting groove 111, completing the unlocking process.

[0050] When the locking plate ring 21 abuts against the rear end face of the clamp 10, and when the positions of the locking hole 22 and the locking rod 51 are staggered, the abutting action of the locking plate ring 21 can prevent the locking rod 51 from extending out of the mounting groove 111, that is, the locking rod 51 is limited in the mounting groove 111, thereby not interfering with the rotation of the locking plate ring 21, and thus realizing the normal rotation of the swivel 20.

[0051] In one embodiment, the locking rod 51 includes a locking cap 511 and a shift block 512. The end of the first elastic member 52 close to the opening side 112 extends into the locking cap 511 and is connected to the locking cap 511. The locking cap 511 is used to insert into the lock hole 22. The shift block 512 has a connecting end and a free end. The connecting end is connected to the locking cap 511, and the free end extends from the connecting end to the inner side of the lock plate ring 21. A push platform 31 is provided on the side of the clamping ring 30 facing the clamping hoop 10. The push platform 31 can pass through the lock plate ring 21 and push the free end toward the direction of the clamping hoop 10 when the clamping ring 30 extends into the swivel 20, so as to drive the locking cap 511 to disengage from the lock hole 22 through the shift block 512.

[0052] Specifically, the end of the first elastic member 52 close to the opening side 112, that is, the rear end of the first elastic member 52, extends into the lock cap 511 and is connected to the lock cap 511, thereby realizing the assembly of the first elastic member 52 and the locking rod 51. The lock cap 511 is used to be inserted into the lock hole 22, and the lock block has a connecting end and a free end. The connecting end is connected to the lock cap 511, and the free end extends from the connecting end to the inside of the lock plate ring 21. It can be understood that the lock plate ring 21 is an annular structure with a hole in the middle. A push platform 31 is provided on the side of the clamp 30 facing the clamp 10, that is, the front side of the clamp 30. When the clamp 30 extends into the swivel 20, the push platform 31 passes through the hole on the inside of the lock plate ring 21, thereby pushing the free end forward, thereby pushing the lock cap 511 forward and disengaging it from the lock hole 22 through the shift block 512, thereby realizing the unlocking process. The structural design is reasonable and ingenious.

[0053] It should be noted that the first elastic member 52 may be a compression spring in the prior art, or may be an elastic column, elastic sheet or other structure with elastic force.

[0054] In one embodiment, the mounting flange 11 is provided with a receiving groove 113 with a notch facing the lock plate ring 21. The receiving groove 113 is spaced apart from the mounting groove 111. The receiving groove 113 extends along the circumference of the mounting flange 11. The reset assembly 40 includes a second elastic member 41 and a slider 42. The second elastic member 41 is provided in the receiving groove 113 along the extension direction of the receiving groove 113. One end of the second elastic member 41 is connected to the groove wall of the receiving groove 113. The other end of the second elastic member 41 is connected to the slider 42. The slider 42 It is arranged in the accommodating groove 113 and can slide along the extension direction of the accommodating groove 113, and the slider 42 is connected to the locking plate ring 21; the locking plate ring 21 is used to drive the slider 42 to slide in the accommodating groove 113 when the rotating ring 20 rotates to the second position, so as to pull the second elastic member 41 to deform; the second elastic member 41 is used to drive the slider 42 to slide in the opposite direction in the accommodating groove 113 through the elastic restoring force when the rotating ring 20 is unlocked, so as to pull the locking plate ring 21 through the slider 42, so that the rotating ring 20 rotates from the second position to the first position.

[0055] Specifically, if Figure 1 and Figure 4 As shown, the notch of the receiving groove 113 is set to face backward, and the receiving groove 113 extends along the circumference of the mounting flange 11. The second elastic member 41 of the reset assembly 40 is set in the receiving groove 113, that is, the second elastic member 41 also extends along the circumference of the mounting flange 11. The slider 42 is slidably set in the receiving groove 113 and connected to the second elastic member 41. The slider 42 is also connected to the lock plate ring 21. The swivel 20 is rotated counterclockwise to the second position, specifically, from the first position to the second position, or from a position between the first and second positions to the second position. During the process of rotating the swivel 20 counterclockwise to the second position, the slider 42 is driven by the lock plate ring 21 to slide counterclockwise in the receiving groove 113, thereby pulling the second elastic member 41 to deform.

[0056] When the collar 30 extends into the swivel 20 and pushes the locking rod 51 to unlock the swivel 20 from the hoop 10, the second elastic member 41 uses its elastic restoring force to drive the slider 42 to rotate clockwise. This, in turn, pulls the locking plate ring 21 through the slider 42, causing the swivel 20 to quickly rotate to the first position, quickly and automatically locking it with the hoop 10 and collar 30. This structural design is rational and ingenious. The accommodating groove 113 is spaced apart from the mounting groove 111 to prevent interference between the reset assembly 40 and the locking assembly 50.

[0057] It should be noted that the second elastic member 41 may be a tension spring in the prior art, or may be an elastic column, an elastic sheet or other structures with elastic force.

[0058] In one embodiment, the locking plate ring 21 is provided with a mounting hole 211, and the locking plate ring 21 is connected to the slider 42 by a first screw 212 passed through the mounting hole 211 and the slot. A decorative plate 70 is provided on the side of the locking plate ring 21 facing the clamping ring 30, and the decorative plate 70 covers the first screw 212 and the mounting hole 211.

[0059] As will be understood, to facilitate the connection between the slider 42 and the lock plate ring 21, a mounting hole 211 is provided in the lock plate ring 21. After the swivel 20 is sleeved onto the clamp 10, the mounting hole 211 is aligned with the slider 42. The lock plate ring 21 and the slider 42 are fastened together using a first screw 212 threaded through the mounting hole 211 and the notch, thereby achieving the connection between the slider 42 and the lock plate ring 21. After the slider 42 and the lock plate ring 21 are connected, the swivel 20 can be rotated counterclockwise to the second position. A decorative plate 70 is provided on the side of the lock plate ring 21 facing the collar 30, that is, toward the rear. The decorative plate 70 obscures the first screw 212 and the mounting hole 211, providing a decorative effect and enhancing the aesthetics of the adapter structure.

[0060] In one embodiment, there are multiple receiving grooves 113, which are spaced apart along the circumference of the mounting flange 11. The number of reset assemblies 40 matches the number of receiving grooves 113 and is arranged in a one-to-one correspondence. The provision of multiple reset assemblies 40 increases the elastic restoring force, allowing the swivel 20 to be pulled to the first position more quickly when it is released from the clamp 10, thereby achieving a faster automatic tightening process with the clamp 10 and the collar 30.

[0061] In one embodiment, a first limiting wall 114 is formed on the outer wall of the mounting flange 11, a second limiting wall 32 is formed on the outer wall of the retaining ring 30, and a first limiting groove 23 and a second limiting groove 24 are respectively provided on the inner wall of the rotating ring 20. The first limiting groove 23 and the second limiting groove 24 are axially arranged on both sides of the locking plate ring 21. The first limiting wall 114 is used to extend into and be limited in the first limiting groove 23, and the second limiting wall 32 is used to extend into and be limited in the second limiting groove 24.

[0062] The first limiting groove 23 and the second limiting groove 24 are respectively formed on the front and rear sides of the interior of the swivel 20. The outer wall of the mounting flange 11 is formed with a first limiting wall 114. When the swivel 20 is sleeved on the clamping hoop 10, the swivel 20 is specifically arranged outside the mounting flange 11, and the swivel 20 rotates to the first position, the first limiting wall 114 extends into and is limited in the first limiting groove 23, ensuring the locking stability of the swivel 20 and the clamping hoop 10. When the clamping ring 30 extends into the swivel 20 from the rear side and rotates to the first position, the second limiting wall 32 extends into and is limited in the second limiting groove 24, ensuring the locking stability of the swivel 20 and the clamping ring 30.

[0063] In one embodiment, there are multiple first limiting walls 114, and the multiple first limiting walls 114 are arranged at intervals along the circumference of the mounting flange 11. Each first limiting wall 114 extends along the circumference of the mounting flange 11 and is inclined in the direction away from the clamping ring 30 from the second position to the first position. A first gap 115 is formed between any two adjacent first limiting walls 114; the inner wall of the rotating ring 20 forms multiple first blocking walls 25 along its circumference, and the number of the first blocking walls 25 is consistent with the number of the first gaps 115. The first blocking wall 25 can pass through any first gap 115, and a first limiting groove 23 is formed between each first blocking wall 25 and the locking plate ring 21.

[0064] Specifically, a first retaining groove 23 is formed between the first retaining wall 25 and the lock plate ring 21, and a first notch 115 is formed between any two adjacent first retaining walls 114 for the first retaining wall 25 to pass through. During the process of sleeve-fitting the swivel 20 onto the mounting flange 11, the multiple first retaining walls 25 pass through the first notches 115 in a one-to-one correspondence, abutting the front sides of the first retaining walls 114. As the swivel 20 rotates clockwise, the first notches 115 and the first retaining walls 25 become misaligned until the mounting hole 211 is aligned with the screw hole of the slider 42. The lock plate ring 21 and the slider 42 are then fastened together by the first screw 212, thereby achieving the connection between the slider 42 and the lock plate ring 21. The swivel 20 is then rotated counterclockwise, and the locking plate ring 21 drives the slider 42 to slide within the corresponding receiving groove 113, thereby pulling the second elastic member 41 to deform until the swivel 20 rotates to the second position, aligning the locking hole 22 with the locking rod 51. The first elastic member 52 pushes the locking rod 51 into the locking hole 22 to lock the swivel 20. It can be understood that the rotation angle of the first blocking wall 25 is limited by the rotation angle of the slider 42 within its receiving groove 113, preventing it from rotating to the first notch 115 and sliding out of the first notch 115.

[0065] When the collar 30 extends into the swivel 20 and pushes the locking rod 51 to unlock the swivel 20 from the clamp 10, the second elastic member 41 uses its elastic restoring force to drive the slider 42 to rotate clockwise, thereby pulling the lock plate ring 21 through the slider 42, causing the swivel 20 to quickly rotate to the first position. The side of the first limiting wall 114 facing away from the collar 30, that is, the front side, forms a first sliding groove 1141 for the first blocking wall 25 to slide. Since the first limiting wall 114 is inclined in the direction from the second position to the first position toward the direction away from the clamping ring 30, that is, the first limiting wall 114 is inclined forward in the clockwise direction, so that the first slide groove 1141 gradually narrows in the clockwise direction, and the first blocking wall 25 abuts the front side of the first limiting wall 114 and slides along the first slide groove 1141, so that when the swivel 20 rotates clockwise to the first position, the first blocking wall 25 is locked as the first slide groove 1141 narrows, thereby realizing the locking of the clamp 10 and the swivel 20. The structural design is reasonable and ingenious.

[0066] In one embodiment, there are multiple second limiting walls 32, and the multiple second limiting walls 32 are arranged at intervals along the circumference of the clamping ring 30. Each second limiting wall 32 extends along the circumference of the clamping ring 30 and is inclined in the direction away from the clamping hoop 10 from the second position to the first position. A second gap 33 is formed between any two adjacent second limiting walls 32; the inner wall of the rotating ring 20 forms a plurality of second blocking walls 26 along its circumference, and the number of the second blocking walls 26 is consistent with the number of the second gaps 33. The second blocking wall 26 can pass through any second gap 33, and a second limiting groove 24 is formed between each second blocking wall 26 and the locking plate ring 21.

[0067] Specifically, each second limiting wall 32 forms a second sliding groove 321 on a side facing away from the clamp 10, i.e., the rear side, for the second blocking wall 26 to slide in. Since the second limiting wall 32 is inclined in the direction away from the clamp 10 from the second position to the first position, i.e., the second limiting wall 32 is inclined backward in the clockwise direction, the second sliding groove 321 gradually narrows in the clockwise direction.

[0068] A second notch 33 is formed between any two adjacent second limiting walls 32, through which the second blocking walls 26 pass. As the collar 30 extends into and fits within the swivel 20, the multiple second blocking walls 26 pass through the second notches 33 in a one-to-one correspondence, abutting the rear sides of the second limiting walls 32. As the swivel 20 rotates clockwise, the second slide groove 321 gradually narrows in the clockwise direction, while the second blocking walls 26 abut the rear sides of the second limiting walls 32 and slide along the second slide groove 321. When the swivel 20 rotates clockwise to the first position, the narrowing of the second slide groove 321 locks the second blocking walls 26, achieving a secure lock between the swivel 20 and the collar 30. This results in a rational and ingenious structural design.

[0069] In one embodiment, a seam 12 is provided on the side wall of the clamp 10, and a first mounting ear 13 and a second mounting ear 14 are respectively provided on both sides of the seam 12. The first mounting ear 13 and the second mounting ear 14 are both provided with a through hole for a second screw 16 to pass through. The second screw 16 cooperates with a wrench 15 with an internal thread to tighten the first mounting ear 13 and the second mounting ear 14 so that the clamp 10 clamps the side of the objective lens.

[0070] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, the first mounting ear 13 is positioned above the second mounting ear 14, and the wrench 15 is positioned above the first mounting ear 13. After the swivel 20 is secured to the clamp 10, the second screw 16 is inserted from bottom to top through the through-holes of the second mounting ear 14 and the first mounting ear 13. The second screw 16, in conjunction with the wrench 15, tightens the first and second mounting ears 13 and 14, securing the clamp 10 against the objective lens, completing assembly with the optical device. The wrench 15 and second screw 16 are used to assemble the clamp 10 to the optical device, making assembly simple, convenient, and easy.

[0071] In one embodiment, the wrench 15 includes a housing 151 and a handle 152. The housing 151 is adapted to receive the stud 161 of the second screw 16. The inner wall of the housing 151 has internal threads that mate with the stud 161. The handle 152 is connected to one side of the housing 151. When the handle 152 is rotated, the housing 151 engages with the stud 161 to securely fasten the first mounting ear 13 and the second mounting ear 14. The adapter structure also includes a locking screw 17 for locking the second screw 16.

[0072] Specifically, the head of the second screw 16 is located at the bottom of the second mounting ear 14, and the stud 161 of the second screw 16 extends into the cover body 151. From the top to the bottom, the handle 152 is turned clockwise to drive the cover body 151 to rotate and engage with the stud 161 of the second screw 16, thereby fastening the first mounting ear 13 and the second mounting ear 14. The structure is simple and convenient and easy to operate.

[0073] A locking hole 142 is formed on the side of the first mounting ear 13 or the side of the second mounting ear 14. After the wrench 15 cooperates with the second screw 16 to tighten the first mounting ear 13 and the second mounting ear 14, the locking screw 17 passes through the locking hole 142 of the first mounting ear 13 or the second mounting ear 14 and presses against the stud 161 of the second screw 16 to lock the stud 161 and ensure fastening reliability.

[0074] Furthermore, the first mounting ear 13 is arranged close to the cover body 151, and the through hole of the first mounting ear 13 is the first through hole 131; a pad 18 is provided between the first mounting ear 13 and the cover body 151, and the pad 18 is provided with a through hole 182 for the stud 161 to pass through, a first locking step 181 is formed on one side of the pad 18, and a second locking step is provided in the first through hole 131. The pad 18 extends into the first through hole 131 so that the first locking step 181 abuts the second locking step, and the other side of the pad 18 extends out of the first through hole 131 and forms a third locking step 183. A fourth locking step 1511 is formed on the side of the cover body 151 facing the pad 18; when the handle 152 is rotated, it can drive the cover body 151 to rotate until the first locking step 181 and the third locking step 183 abut against the second locking step and the fourth locking step 1511 respectively, so as to narrow the seam 12.

[0075] The pad 18 is positioned between the cover 151 and the first mounting ear 13. The bottom edge of the pad 18 forms a downwardly protruding first locking step 181. The bottom side of the pad 18 extends into the first through-hole 131, causing the first locking step 181 to abut against the second locking step. The second locking step provides support and prevents the pad 18 from falling. The top side of the pad 18 extends out of the first through-hole 131 and forms an upwardly protruding third locking step 183. A downwardly protruding fourth locking step 1511 is formed on the bottom side of the cover 151.

[0076] After stud 161 of second screw 16 extends into housing 151, handle 152 is rotated clockwise. As the fourth locking step 1511 rotates, it rises to face and abut against third locking step 183, pressing down on pad 18. This causes first locking step 181 of pad 18 to abut against the second locking step, bringing first mounting ear 13 and second mounting ear 14 closer together, thereby narrowing joint 12. Handle 152 is further rotated clockwise, and the threaded engagement between housing 151 and stud 161 secures first mounting ear 13 and second mounting ear 14. Pad 18 enhances the fastening force between first mounting ear 13 and second mounting ear 14, improving fastening reliability.

[0077] It is understood that after the first mounting ears 13 and the second mounting ears 14 are fastened, the seam 12 can be further narrowed or closed, so that the clamping ring 10 can be tightly clamped to the objective lens side of the optical device. Utilizing the clamping force of the clamping ring 10 to achieve fixation to the optical device, it can be clamped to optical devices of different outer diameters, has good versatility, and has the advantages of simple structure and easy operation.

[0078] like Figure 2 and Figure 3 As shown, in one embodiment, the clamp 10 has a mounting space 19 for the objective lens to extend into. The inner wall of the mounting space 19 is provided with a non-slip pad 191 that contacts the outer wall of the objective lens. When the clamp 10 is clamped to the objective lens of the optical device, the non-slip pad 191 surrounds the objective lens and contacts the outer wall of the objective lens, thereby increasing the friction between the clamp 10 and the optical device and improving the assembly stability between the clamp 10 and the optical device. In addition, the non-slip pad 191 also provides protection, preventing damage to the outer wall of the objective lens.

[0079] The above description is merely an optional embodiment of the present invention and does not limit the scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
