Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: a handle locking mechanism for a confocal endoscope, comprising a handle body 1, an anti-drop component on the outer side of the handle body 1, and a locking component inside the handle body 1. The anti-drop component includes a fixing frame 21 fixedly connected to the handle body 1, a plurality of four sliding grooves 22 evenly arranged on one side of the fixing frame 21, a sliding rod 23 disposed in the sliding groove 22, a spring 24 fixedly connected to one end of the sliding rod 23, an anti-detachment plate 25 fixedly connected to the other end of the sliding rod 23, and a buffer pad 26 fixedly connected to the anti-detachment plate 25. The sliding rod 23 is slidably connected to the sliding groove 22. The anti-detachment plate 25 and the buffer pad 26 are arc-shaped, allowing fingers to be inserted into the fixing frame 21. The fingers can squeeze the anti-detachment plate 25 to move, and the movement of the anti-detachment plate 25 can drive the sliding rod 23 to move. The sliding rod 23 can squeeze the spring 24 to deform it, utilizing the spring... The elasticity of the spring 24 can push the anti-slip plate 25 to press down the fingers, fixing the fingers between the anti-slip plate 25 and the handle body 1, preventing the handle from slipping and ensuring grip stability. The cushioning pad 26 can improve grip comfort. A limit groove 41 is opened on one side of the slide bar 23, and a limit plate 42 is fixedly connected to the inner wall of the slide groove 22. The limit plate 42 is slidably connected to the limit groove 41. When the slide bar 23 moves, the limit plate 42 can slide in the limit groove 41. The limit plate 42 can limit the deformation distance of the spring 24, preventing the spring 24 from being damaged due to excessive deformation. An anti-slip pad 71 is fixedly connected to the outside of the handle body 1. The anti-slip pad 71 has anti-slip texture 711 on the outside. The anti-slip pad 71 and the anti-slip texture 711 can increase the friction between the palm and the handle body 1, further improving the grip performance and further preventing the handle body 1 from falling.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5The locking components include a retaining ring 31 fixedly connected to the inner wall of the handle body 1, a lead screw 32 connected to the retaining ring 31, a knob 33 fixedly connected to one end of the lead screw 32, a drive frame 34 connected to the outer side of the lead screw 32, and a locking plate 35 fixedly connected to the drive frame 34. The lead screw 32 is screwed to the drive frame 34. The lead screw 32 is rotatably connected to both the handle body 1 and the retaining ring 31. The cable can be inserted into the handle body 1 from the bottom. The knob 33 can rotate the lead screw 32, which can drive the drive frame 34 to move laterally, thereby moving the locking plate 35. The movement of the two locking plates 35 can lock the cable, preventing the cable from moving vertically. To protect the cable from damage, two extension rods 51 are fixedly connected to both sides of the inner ring 31. The drive frame 34 has openings 52 on both sides. The extension rods 51 are slidably connected to the openings 52. The two extension rods 51 are evenly distributed along the axis of the lead screw 32. The movement of the drive frame 34 allows the openings 52 to slide outside the extension rods 51. The extension rods 51 can be used to stop the drive frame 34 from rotating synchronously with the lead screw 32, ensuring the lateral stable movement of the locking plate 35. A protective sleeve 61 is fixedly connected to the bottom of the handle body 1. The protective sleeve 61 is made of rubber and can further protect the cable and prevent further damage.

[0025] Working principle: During operation, insert the cable into the handle body 1 from the bottom. Then, rotate the knobs 33 on both sides of the knob 33. Rotating the knob 33 will drive the lead screw 32 to rotate. The rotation of the lead screw 32 will drive the drive frame 34 to move. Due to the presence of the extension rod 51, the drive frame 34 will not rotate. The movement of the drive frame 34 will drive the locking plate 35 to move. The movement of the locking plate 35 will lock and fix the cable, preventing the cable from moving or swinging. Then, insert four fingers into the fixing bracket 21 and hold the handle body 1. The fingers can... The buffer pad 26 contacts and pushes the buffer pad 26 to move the anti-detachment plate 25. The movement of the anti-detachment plate 25 can move the slide rod 23. The movement of the slide rod 23 can compress the spring 24 to deform it. The thrust generated by the deformation of the spring 24 can fix the finger between the anti-detachment plate 25 and the handle body 1, which can press and fix the finger, prevent the handle body 1 from falling off due to hand slippage, and protect the handle body 1. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
