[0020] The present invention will be further described in detail below with reference to the embodiments.

[0021] Example 1, refer to the attached Figure 1-8 As shown, in order to solve the problem in the prior art that different components need to be individually manipulated to clamp and adjust the shooting angle, the present invention discloses a fixing device for an industrial endoscope that is easy to install, including: a support frame 1, which has a supporting effect. The support frame 1 is a carrier that connects all components together. A first fixing rod 5 is fixedly connected to the surface of the support frame 1. The first fixing rod 5 serves as an extension of the support frame 1 to achieve the effect of connecting and fixing other components, so that the first threaded rod 2 rotates on the first fixing rod 5, and a first clamping plate 3 is fixedly connected to the bottom of the support frame 1. 3, through the cooperation of the first clamping plate 3 and the second clamping plate 4, it can be clamped and thus fixed on the workbench, and the first threaded rod 2 connected between the first clamping plate 3 and the first fixing rod 5 is rotated. The first threaded rod 2 rotates on the first fixing rod 5 and the first clamping plate 3 and cannot move up and down. It can only rotate at this position, and has the effect of driving the guide block 74 and the second clamping plate 4 when rotating. The second clamping plate 4 engaged with the first threaded rod 2 is driven to move up and down by the rotation of the first threaded rod 2, so that the second clamping plate 4 and the first clamping plate 3 can cooperate on the workbench to clamp or release the workbench; The clamping seat 6 is provided above the support frame 1. The clamping seat 6 is a U-shaped structure. The clamping seat 6 cooperates with the clip 10 to clamp or release the endoscope. The clip 10 is slidably connected to the clamping seat 6. The clip 10 can slide on the clamping seat 6, and one side of the clip 10 passes through the clamping seat 6 to achieve a limiting effect on the clip 10. The second threaded rod 11 connected to the surface of the clip 10 is rotated. The second threaded rod 11 can rotate on the clip 10, and while rotating, it pushes the clip 10 forward or backward, so that the clip 10 and the clamping seat 6 have the effect of clamping or releasing the endoscope; The limiting component 7 provided on the support frame 1 has the effect of straightening the connecting line and limiting the connecting line. The control component 8 provided on the first fixed rod 5 has the effect of controlling the angle adjustment component 9 and controlling the limiting component 7. Both the limiting component 7 and the angle adjustment component 9 are driven by rotation, so the control component 8 is provided with a rotation component. The control component 8 moves close to the angle adjustment component 9, thereby driving the angle adjustment component 9 through the control component 8 to control the shooting angle of the endoscope. The control component 8 moves close to the first threaded rod 2, thereby controlling the limiting component 7, the first clamping plate 3 and the second clamping plate 4, thereby simultaneously controlling the clamping and separation of the first clamping plate 3 and the second clamping plate 4 on the workbench, as well as the limiting of the connecting line through the limiting component 7, and the angle adjustment component 9 provided on the support frame 1 for rotating the clamping seat 6, the angle adjustment component 9 has the effect of controlling the endoscope, the clamping seat 6, the clamping piece 10 and the second threaded rod 11 to adjust the shooting angle; When the second clamping plate 4 is in close contact with the first clamping plate 3, the guide block 74 stops moving and passes through the limiting telescopic rod 71 of the support frame 1. The limiting telescopic rod 71 drives the first rotating rod 73 to approach the other first rotating rod 73, thereby limiting the connection line. The first spring 76 is mounted on the surface of the support frame 1, and the first spring 76 is used to cooperate with the telescopic limit rod 71 to form a frame to limit the connecting line. The two first rotating rods 73 connected to the telescopic limit rod 71 and the first telescopic limit rod 72 are rotated respectively. The first rotating rod 73 rotates to facilitate the connection line to move while being limited between the first rotating rods 73. The dome rod 75 is fixedly connected to the end of the telescopic limit rod 71. The dome rod 75 is cylindrical, which is convenient for less friction when fitting with the guide block 74, thereby moving more smoothly, driving the telescopic limit rod 71 to move, and the first spring 76 mounted on the surface of the telescopic limit rod 71. Through the action of the first spring 76, the dome rod 75 drives the telescopic limit rod 71 to rest against the first threaded rod 2 or the guide block 74.

[0022] The angle adjustment assembly 9 includes a cam seat 93 fixedly connected to the top of the support frame 1, which plays the role of supporting the top rod 92 and the first cam 91 through the cam seat 93. At the same time, the second rotating rod 94 is pressed against the cam seat 93 under the drive of the torsion spring 95, which has the effect of limiting the cam seat 93. The top rod 92 connected to the cam seat 93 is rotated, and the top rod 92 can drive the first cam 91 to rotate. The top rod 92 rotates on the cam seat 93 and is fixedly connected to the first cam 91 at the top of the top rod 92. The first cam 91 is designed as an eccentric wheel. When the first cam 91 rotates, it can press against the side of the second rotating rod 94, thereby driving the second rotating rod 94 to rotate along the contour of the first cam 91 and fixedly connected to the The second hexagonal rod 83 at the bottom of the top rod 92 can cooperate with the upward hexagonal sleeve 87, and rotate under the rotation of the hexagonal sleeve 87, thereby driving the top rod 92 and the first cam 91 to rotate, thereby controlling the angle adjustment of the endoscope, rotating the second rotating rod 94 connected to the cam seat 93, the second rotating rod 94 rotates on the cam seat 93, thereby driving the clamping seat 6 and the endoscope to rotate, adjusting the shooting angle, and the torsion spring 95 clamped between the cam seat 93 and the second rotating rod 94, the torsion spring 95 drives the second rotating rod 94 to press against the cam seat 93, and when the first cam 91 presses against the second rotating rod 94 and moves, the second rotating rod 94 moves away from the cam seat 93.

[0023] The control assembly 8 includes a second fixed rod (81) on the first fixed rod (5), the second fixed rod 81 is fixedly connected between the cam seat 93 and the first fixed rod 5, the second fixed rod 81 facilitates the sliding seat 88 to move up and down on the second fixed rod 81, thereby determining whether to control the rotation of the second hexagonal rod 83 or the first hexagonal rod 82, and the first hexagonal rod 82 is fixedly connected to the top of the first threaded rod 2. The first hexagonal rod 82 can cooperate with the downward-moving hexagonal sleeve 87 to rotate, thereby driving the first threaded rod 2 Rotate the slide 88 on the second fixed rod 81, and the slide 88 can move up and down on the second fixed rod 81, thereby driving the hexagonal sleeve 87 to move up and down, so that the hexagonal sleeve 87 is inserted into the first hexagonal rod 82, or the hexagonal sleeve 87 is inserted into the second hexagonal rod 83, and the hexagonal sleeve 87 connected to the slide 88 is rotated. The hexagonal sleeve 87 can be inserted into the second hexagonal rod 83 or the first hexagonal rod 82, driving the second hexagonal rod 83 or the first hexagonal rod 82 to rotate; The second bevel gear 84 is fixedly connected to the outer surface of the hexagonal sleeve 87, and the second bevel gear 84 can drive the hexagonal sleeve 87 to rotate, and the driving rod 86 connected to the slide 88 is rotated. The driving rod 86 rotates to drive the first bevel gear 85 to rotate, so as to achieve the effect of rotating the second bevel gear 84 and the hexagonal sleeve 87. The first bevel gear 85 is fixedly connected to the end of the driving rod 86, and the first bevel gear 85 is meshed with the second bevel gear 84, so that the rotation of the first bevel gear 85 can drive the second bevel gear 84 and the hexagonal sleeve 87 to rotate, thereby controlling the first hexagonal rod 82 or the second hexagonal rod 83 to rotate, and the pull rod 89 that passes through the slide 88 can be extended in and out on the slide 88, so as to rotate the second bevel gear 84 and the hexagonal sleeve 87. The pull rod 89 is extended into and pulled out from the through hole of the fixed rod 81, thereby fixing the position of the slide 88 on the second fixed rod 81. When the pull rod 89 is pulled out, the slide 88 can slide on the second fixed rod 81. When the pull rod 89 is extended into the second fixed rod 81, the slide 88 is fixed on the second fixed rod 81 and cannot be moved. The blocking block 891 is fixedly connected to the surface of the pull rod 89. The blocking block 891 has the effect of blocking the second spring 892, so that the pull rod 89 has the force to move toward the second fixed rod 81 under normal circumstances, so that the pull rod 89 is extended into the second fixed rod 81 with a better fastening effect. The second spring 892 is sleeved on the pull rod 89, and the second spring 892 presses against the slide 88 to drive the blocking block 891 and the pull rod 89 to move toward the second fixed rod 81.

[0024] The second splint 4 is slidably sleeved on the support frame 1, so that the second splint 4 moves up and down along the support frame 1, limiting the second splint 4. A protective shell 12 is fixedly connected to the support frame 1, and the protective shell 12 has a protective effect on the components, wrapping the support frame 1 and the limit assembly 7, the control assembly 8, and the angle adjustment assembly 9, leaving the slide 88 and the drive rod 86 exposed, thereby controlling the up and down movement of the control assembly 8, and controlling the limit assembly 7 and the angle adjustment assembly 9.

[0025] The second threaded rod 11 is engaged and connected in the clamp seat 6, and the clamp seat 6 is threadedly inserted into the clamp seat 6, so that turning the second threaded rod 11 can drive the clip 10 forward or backward, controlling the clip 10 and the clamp seat 6 to cooperate to clamp or release the endoscope, and the clip 10 passes through the clamp seat 6, and one side of the clip 10 passes through the interior of the clamp seat 6, thereby limiting the clip 10, making the movement of the clip 10 more stable, and the surface of the clamp seat 6 is fixedly connected to the surface of the second rotating rod 94, and the clamp seat 6 is fixedly connected to the rod on the left side of the second rotating rod 94, and the rotation of the clamp seat 6 is controlled by the rotation of the second rotating rod 94, so as to achieve the effect of controlling the shooting angle of the endoscope.

[0026] A blocking piece is fixedly connected between the limiting telescopic rod 71 and the dome rod 75, and the blocking piece allows the first spring 76 to rest against it. The first spring 76 is located between the blocking piece and the support frame 1, so that under normal circumstances, the limiting telescopic rod 71 can use the pushing force of the first spring 76 to push the dome rod 75 with the limiting telescopic rod 71 toward the guide block 74, so that the dome rod 75 can fit on the guide block 74.

[0027] The guide block 74 is mounted on the support frame 1 so that the guide block 74 can move up and down along the direction of the support frame 1, which has a limiting effect on the guide block 74. The surface of the guide block 74 fits with the surface of the dome rod 75, so that the guide block 74 can push the dome rod 75 and the limiting telescopic rod 71 to move, so that the guide block 74 moves along the side track of the guide block 74.

[0028] The second fixed rod 81 is provided with a plurality of through holes, which facilitate the pull rod 89 to pass through the slide 88 and be inserted into the through holes, thereby fixing the slide 88 on the second fixed rod 81. The pull rod 89 passes through the slide 88 and extends to the through hole on the second fixed rod 81. Through the action force of the second spring 892, the blocking block 891 and the pull rod 89 are pushed toward the second fixed rod 81, thereby limiting the slide 88 on the second fixed rod 81.

[0029] The second spring 892 is located between the blocking block 891 and the slide 88, which facilitates the pull rod 89 and the blocking block 891 to move toward the second fixed rod 81 with the help of the reaction force of the second spring 892 and the slide 88. The second bevel gear 84 and the first bevel gear 85 are meshed and connected, so that when the driving rod 86 drives the first bevel gear 85 to rotate, it drives the second bevel gear 84 to rotate, thereby driving the hexagonal socket 87 to rotate on the slide 88.

[0030] Working principle: screw the second threaded rod 11 to fix the endoscope between the clip 10 and the clamping seat 6; S1. Pull the pull rod 89, and by pulling the driving rod 86, the slide 88 moves downward, so that the hexagonal sleeve 87 is sleeved on the first hexagonal rod 82, and the pull rod 89 is loosened so that the pull rod 89 is inserted into the through hole on the second fixing rod 81 to fix the slide 88. At this time, align the second clamping plate 4 and the first clamping plate 3 with the work surface and insert them, pull the connecting line of the endoscope to the two first rotating rods 73, the limiting telescopic rod 71 and the first limiting rod 72, and then rotate the driving rod 86, so that the first bevel gear 85 drives the second bevel gear 84 to rotate. The first hexagonal rod 82 and the first threaded rod 2 are rotated, so that the guide block 74 and the second clamping plate 4 move downward at the same time. At this time, the dome rod 75 passes the slope of the guide block 74, restricting the connecting line between the limiting telescopic rod 71, the first limiting rod 72 and the two first rotating rods 73. The guide block 74 continues to move downward. The dome rod 75 no longer moves after passing the slope of the guide block 74 until the first clamping plate 3 and the second clamping plate 4 are clamped on the work surface, and the rotation of the driving rod 86 is stopped. S2. When the shooting angle of the endoscope needs to be adjusted, pull the pull rod 89 to move the slide 88 upward so that the hexagonal sleeve 87 is sleeved on the second hexagonal rod 83. At this time, loosen the pull rod 89 so that the pull rod 89 is inserted into the through hole on the second fixed rod 81, and fix the slide 88 on the second fixed rod 81. At this time, rotate the drive rod 86 so that the second hexagonal rod 83 drives the top rod 92 and the first cam 91 to rotate. The rotation of the first cam 91 drives the second rotating rod 94 to rotate, thereby driving the endoscope clamped by the clamp 6 and the clip 10 to rotate, thereby achieving the effect of adjusting the shooting angle of the endoscope.
