Description

Technical Field

[0001] The invention relates to the technical field of medical instruments and equipment, in particular to an endoscope-assisted traction device for gastroenterology. Background Art

[0002] Digestive system endoscopy refers to an examination using a tubular instrument that can directly visualize lesions of the gastrointestinal tract and abdominal organs under light illumination. In order to improve the efficiency of the use of the endoscope, the endoscope needs to be pulled. The auxiliary traction device is a medical device used during gastrointestinal endoscopic examination or treatment to help doctors operate and observe better.

[0003] Among them, the traction device is usually used to gently pull the diseased area to expose it more clearly. The diseased area often needs to be clamped for better traction. It usually needs to be adjusted individually according to the patient's physical condition and treatment progress. Commonly used adjustment devices usually use knobs or levers for adjustment, but multiple components need to be adjusted at a time, the operation is more complicated, and the adjustment speed is affected. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a digestive internal medicine endoscope auxiliary tractor, comprising a shell, three limit rings are fixedly connected to the inner wall of the shell, a handle is fixedly connected to the side wall of the shell, and a rubber expansion block is fixedly connected to the outer wall of the handle;

[0005] The adjusting mechanism comprises an inclined frame fixedly connected to the side wall of the shell, a curved extrusion plate is slidably connected to the side wall of the inclined frame, two spring plates are slidably connected to the inner wall of the curved extrusion plate, the side walls of the two spring plates are fixedly connected to inclined friction blocks, two connecting plates are slidably connected to the inner wall of the adjusting mechanism, the side walls of the two connecting plates are fixedly connected to the side walls of the spring plates, a round ball soft rod is slidably connected to the inner wall of the shell, the outer wall of the round ball soft rod is slidably connected to the inner walls of three limit rings, and a buffer assembly is arranged on the side wall of the shell;

[0006] The clamping mechanism includes a fixing ring fixedly connected to the inner wall of the shell, four clamping blocks are rotatably connected to the inner wall of the fixing ring, arc springs are fixedly connected to the side walls of the four clamping blocks, and the sides of the four arc springs away from the clamping blocks are fixedly connected to the left side of the fixing ring. An expansion component is arranged on the side wall of the shell. The user holds the handle and the rubber expansion block, and then presses the arc extrusion plate to descend, driving the spring plate and the inclined friction block to descend, so that the inclined surface of the inclined friction block contacts the inclined surface of the inclined frame. At this time, the inclined friction block will be squeezed, causing the spring plate to retract into the arc-shaped extrusion plate, allowing the spring plate to accumulate resilience. At the same time, when the arc-shaped extrusion plate descends, the arc surface at the bottom of the arc-shaped extrusion plate will contact the surface of the spherical soft rod, thereby squeezing the spherical soft rod to move toward the fixed ring. The spherical soft rod will squeeze the clamping block, causing the clamping block to rotate, so that the four clamping blocks are close to each other. At the same time, the arc spring is stretched to accumulate resilience, and the four clamping blocks can clamp the diseased area. After the clamping is completed, The pressing on the arc-surface extrusion plate can be cancelled. Since the surface of the inclined friction block is relatively rough and the friction force is relatively large, and since the rebound force of the spring plate is smaller than the friction force, the arc-surface extrusion plate will stop. Adjust the clamping force of the clamping block again. When the clamping force needs to be increased, just press the arc-surface extrusion plate again, and the spherical soft rod will continue to be squeezed, thereby continuing to squeeze the clamping block, allowing the clamping block to increase the clamping force. When the clamping force needs to be reduced, press the connecting plate to retract the spring plate into the arc-surface extrusion plate. Separate the inclined friction block from the inclined frame. At this time, the rebound force of the arc spring will be released, allowing the clamping block to return to its position. Squeeze the side of the spherical soft rod close to the clamping block to allow the spherical soft rod to return to its position, thereby moving the clamping blocks away from each other and weakening the clamping force on the diseased part. At the same time, the spherical soft rod will lift the arc surface extrusion plate. The size of the clamping force is controlled by the pressing depth of the arc surface extrusion plate to ensure that the diseased part is accurately clamped. The clamping force can be quickly adjusted by simply pressing the arc surface extrusion plate or extruding the connecting plate.

[0007] Preferably, the buffer assembly includes two fixed blocks fixedly connected to the side walls of the outer shell, two connecting rods are fixedly connected to the top of the arc extrusion plate, and two rotating frames are rotatably connected to the side walls of the outer shell. The bottoms of the two connecting rods are slidingly connected to the inner walls of the rotating frames. When the arc extrusion plate descends, the connecting rods will also be driven to descend, allowing the connecting rods to push the rotating frames to rotate, causing the rotating frames to tilt.

[0008] Preferably, the buffer assembly also includes a sliding plate slidably connected to the inner wall of the fixed block, hydraulic oil is provided on the inner walls of the two fixed blocks, connecting frames are slidably connected to the inner walls of the two fixed blocks, and the side walls of the two connecting frames are slidably connected to the inner wall of the rotating frame, thereby pushing the connecting frame away from the connecting rod and driving the sliding plate to move. Since there is hydraulic oil inside the fixed block, the sliding plate will squeeze the hydraulic oil when it moves, and the squeezed hydraulic oil will enter the connecting hole.

[0009] Preferably, the buffer assembly further comprises a connecting hole provided on the inner wall of the fixed block, the side walls of the two connecting frames are fixedly connected to the side walls of the sliding plate, and the inner walls of the two fixed blocks are provided with special-shaped grooves, which are transported into the special-shaped grooves through the connecting hole and finally enter the right side of the sliding plate through the special-shaped grooves. Figure 6 As shown, when the spherical soft rod returns to lift the arc extrusion plate, the connecting rod will also rise, allowing the sliding plate to return to its position and squeeze the hydraulic oil near the special-shaped groove. Due to the shape of the special-shaped groove, there are multiple branched serpentine channels, so that when the hydraulic oil in the connecting hole enters the special-shaped groove, the liquid flows along the main channel and the fluid is almost unobstructed. However, when flowing in the opposite direction, the liquid will be guided into these complex branch channels. The shape of these channels makes the fluid flow encounter greater resistance, blocking the sliding plate and slowing down the return speed of the sliding plate.

[0010] Preferably, the expansion assembly includes two fixed frames fixedly connected to the side walls of the shell, the inner walls of the two fixed frames are slidably connected with a transverse plate 1, and the side walls of the two transverse plates 1 are fixedly connected with a fixing rod.

[0011] Preferably, the expansion assembly also includes a fixing plate fixedly connected to the outer wall of the connecting frame, the inner walls of the two fixing plates are fixedly connected to the outer wall of the fixing rod, and the inner walls of the two fixing frames are connected through three gas pipes. When the connecting frame is away from the fixing block, the fixing plate will be driven to move, and the fixing rod will move together, so that the transverse plate will move away from the spherical soft rod. When the transverse plate moves, it will squeeze the gas in the fixed frame.

[0012] Preferably, the expansion assembly also includes a connecting frame fixedly connected to the side wall of the fixed frame, and the outer walls of the six air pipes are connected to the inner wall of the rubber expansion block. The squeezed gas enters the rubber expansion block through the air pipes, thereby expanding the rubber expansion block to better fit the user's hand.

[0013] Preferably, the expansion assembly also includes a transverse plate 2 slidably connected to the inner wall of the connecting frame, the inner walls of the two transverse plates 2 are fixedly connected to the outer wall of the fixed rod, and the bottoms of the two connecting frames are connected with seven air outlet pipes. When the fixed rod is moved together with the fixed plate, the fixed rod will also drive the transverse plate 2 to move, allowing the transverse plate 2 to squeeze the gas in the connecting frame, and the squeezed gas will be sprayed toward the hands of the user through the air outlet pipe.

[0014] The present invention has the following beneficial effects:

[0015] (1) When the present invention is used, the user holds the handle and the rubber expansion block, and then presses the arc-surface extrusion plate to descend, thereby driving the spring plate and the inclined friction block to descend, and allowing the inclined surface of the inclined friction block to contact the inclined surface of the inclined frame. At this time, the inclined friction block will be squeezed, causing the spring plate to retract into the arc-surface extrusion plate, so that the spring plate accumulates rebound force. At the same time, when the arc-surface extrusion plate descends, the arc surface at the bottom of the arc-surface extrusion plate will contact the surface of the spherical soft rod, thereby squeezing the spherical soft rod to move toward the fixing ring. The spherical soft rod will squeeze the clamping block, causing the clamping block to rotate, so that the four clamping blocks are close to each other. At the same time, the arc spring is stretched to allow the arc spring to accumulate rebound force, and the four clamping blocks can clamp the diseased area. After clamping is completed, the pressing of the arc-surface extrusion plate can be cancelled. Since the surface of the inclined friction block is relatively rough and the friction force is relatively large, and since the rebound force of the spring plate is smaller than Friction, so the arc extrusion plate will stop, and the clamping force of the clamping block will be adjusted again. When the clamping force needs to be increased, just press the arc extrusion plate again, and the spherical soft rod will continue to be squeezed, thereby continuing to squeeze the clamping block, allowing the clamping block to increase the clamping force. When the clamping force needs to be reduced, press the connecting plate to retract the spring plate into the arc extrusion plate, and separate the inclined friction block from the inclined frame. At this time, the rebound force of the arc spring will be released, allowing the clamping block to return to its position, and squeeze the side of the spherical soft rod close to the clamping block to allow the spherical soft rod to return to its position, thereby allowing the clamping blocks to move away from each other, weakening the clamping force on the diseased part. At the same time, the spherical soft rod will lift the arc extrusion plate, and the size of the clamping force is controlled by the pressing depth of the arc extrusion plate to ensure that the diseased part is accurately clamped. The clamping force can be quickly adjusted by pressing the arc extrusion plate or squeezing the connecting plate.

[0016] (2) When the arc-surface extrusion plate of the present invention descends, it also drives the connecting rod to descend, so that the connecting rod drives the rotating frame to rotate, causing the rotating frame to tilt, thereby pushing the connecting frame away from the connecting rod, driving the sliding plate to move. Since the fixed block contains hydraulic oil, when the sliding plate moves, it will squeeze the hydraulic oil, and the squeezed hydraulic oil will enter the connecting hole, be transported into the special-shaped groove through the connecting hole, and finally enter the right side of the sliding plate through the special-shaped groove, such as Figure 6 As shown, when the spherical soft rod returns to lift the arc-surface extrusion plate, the connecting rod will also rise, allowing the sliding plate to return and squeeze the hydraulic oil near the special-shaped groove. Due to the shape of the special-shaped groove, there are multiple branched serpentine channels, so that when the hydraulic oil flows into the special-shaped groove through the connecting hole, the liquid flows along the main channel and the fluid is almost unobstructed. However, when flowing in the opposite direction, the liquid will be guided into these complex branch channels. The shape of these channels makes the fluid flow encounter greater resistance, blocking the sliding plate and slowing down the return speed of the sliding plate, thereby slowing down the return speed of the arc-surface extrusion plate, effectively preventing the arc spring from rebounding too quickly, which may cause a large separation distance of the clamping blocks and affect the adjustment of the clamping force, and can more accurately adjust the required clamping force.

[0017] (3) When the connecting frame of the present invention is away from the fixed block, it will drive the fixed plate to move and move the fixed rod together, so that the transverse plate will move away from the spherical soft rod. When the transverse plate moves, it will squeeze the gas in the fixed frame. The squeezed gas will enter the rubber expansion block through the air pipe, so that the rubber expansion block will expand and better fit the user's hand, reducing the discomfort of the user holding the handle for a long time, and effectively preventing the user from getting tired due to holding for a long time, which affects the control of the precise force of pressing the arc extrusion plate.

[0018] (4) In the present invention, when the fixed rod is driven by the fixed plate to move, the fixed rod will also drive the transverse plate 2 to move, so that the transverse plate 2 squeezes the gas in the connecting frame. The squeezed gas will be sprayed toward the user's hands through the air outlet pipe. When the arc surface extrusion plate is frequently pressed or the arc surface extrusion plate is raised, the transverse plate 2 will frequently reciprocate on the inner wall of the connecting frame, and the air outlet pipe will frequently spray light gas toward the user's hands. The small airflow brought by the frequent light gas spraying helps to relieve the tension or discomfort of the hand muscles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figure 1-Figure 5 The present invention is an endoscope auxiliary traction device for gastroenterology, comprising a shell 1, three limit rings 11 are fixedly connected to the inner wall of the shell 1, a handle 12 is fixedly connected to the side wall of the shell 1, and a rubber expansion block 13 is fixedly connected to the outer wall of the handle 12;

[0032] The adjusting mechanism 2 includes an inclined frame 21 fixedly connected to the side wall of the shell 1, a curved extrusion plate 22 is slidably connected to the side wall of the inclined frame 21, two spring plates 23 are slidably connected to the inner wall of the curved extrusion plate 22, and inclined friction blocks 231 are fixedly connected to the side walls of the two spring plates 23, two connecting plates 24 are slidably connected to the inner wall of the adjusting mechanism 2, and the side walls of the two connecting plates 24 are fixedly connected to the side walls of the spring plates 23, a spherical soft rod 25 is slidably connected to the inner wall of the shell 1, and the outer wall of the spherical soft rod 25 is slidably connected to the inner walls of the three limit rings 11, and a buffer component 4 is provided on the side wall of the shell 1;

[0033] The clamping mechanism 3 includes a fixing ring 31 fixedly connected to the inner wall of the housing 1, and four clamping blocks 32 are rotatably connected to the inner wall of the fixing ring 31. The side walls of the four clamping blocks 32 are fixedly connected with arc springs 33. The sides of the four arc springs 33 away from the clamping blocks 32 are fixedly connected to the left side of the fixing ring 31. The side wall of the housing 1 is provided with an expansion component 5. The user holds the handle 12 and the rubber expansion block 13, and then presses the arc extrusion plate 22 to descend, driving the spring plate 23 and the inclined friction block 231 to descend, so that the inclined surface of the inclined friction block 231 and the inclined frame 21, at this time, the inclined friction block 231 will be squeezed, so that the spring plate 23 is retracted into the arc surface squeezing plate 22, so that the spring plate 23 accumulates resilience. At the same time, when the arc surface squeezing plate 22 descends, the arc surface at the bottom of the arc surface squeezing plate 22 will contact the surface of the spherical soft rod 25, thereby squeezing the spherical soft rod 25 to move toward the fixing ring 31. The spherical soft rod 25 will squeeze the clamping block 32, so that the clamping block 32 rotates, so that the four clamping blocks 32 are close to each other. At the same time, the arc spring 33 is stretched to allow the arc spring 33 to accumulate resilience, and the four clamping blocks 32 can be used to treat the lesion. After clamping, the pressing of the arc-surface extrusion plate 22 can be cancelled. Since the surface of the inclined friction block 231 is relatively rough and the friction force is relatively large, and since the rebound force of the spring plate 23 is less than the friction force, the arc-surface extrusion plate 22 will stop, and the clamping force of the clamping block 32 can be adjusted again. When the clamping force needs to be increased, the arc-surface extrusion plate 22 only needs to be pressed again, and the spherical soft rod 25 will continue to be squeezed, thereby continuing to squeeze the clamping block 32, so that the clamping block 32 increases the clamping force. When the clamping force needs to be reduced, the connecting plate 24 is pressed to retract the spring plate 23 into the arc-surface extrusion plate 22, the inclined friction block 231 is separated from the inclined frame 21. At this time, the resilience of the arc spring 33 will be released, allowing the clamping block 32 to return to its original position, and the side of the spherical soft rod 25 close to the clamping block 32 will be squeezed to allow the spherical soft rod 25 to return to its original position, so that the clamping blocks 32 are separated from each other, and the clamping force on the diseased part is weakened. At the same time, the spherical soft rod 25 will lift the arc surface squeezing plate 22. The size of the clamping force is controlled by the pressing depth of the arc surface squeezing plate 22 to ensure that the diseased part is accurately clamped. The clamping force can be quickly adjusted by pressing the arc surface squeezing plate 22 or squeezing the connecting plate 24.

[0034] For example 2, please refer to Figure 6-Figure 8The present invention is an endoscope auxiliary traction device for gastroenterology. On the basis of Example 1, the buffer component 4 includes two fixed blocks 41 fixedly connected to the side wall of the shell 1, two connecting rods 42 are fixedly connected to the top of the arc extrusion plate 22, and two rotating frames 43 are rotatably connected to the side wall of the shell 1. The bottoms of the two connecting rods 42 are slidably connected to the inner wall of the rotating frame 43. When the arc extrusion plate 22 descends, the connecting rods 42 will also be driven to descend, so that the connecting rods 42 push the rotating frame 43 to rotate, and the rotating frame 43 will be tilted.

[0035] The buffer assembly 4 also includes a sliding plate 45 slidably connected to the inner wall of the fixed block 41. Hydraulic oil is provided on the inner walls of the two fixed blocks 41. The inner walls of the two fixed blocks 41 are slidably connected with a connecting frame 44. The side walls of the two connecting frames 44 are slidably connected to the inner wall of the rotating frame 43, thereby pushing the connecting frame 44 away from the connecting rod 42 and driving the sliding plate 45 to move. Since there is hydraulic oil inside the fixed block 41, when the sliding plate 45 moves, it will squeeze the hydraulic oil, and the squeezed hydraulic oil will enter the connecting hole 46.

[0036] The buffer assembly 4 also includes a connecting hole 46 opened on the inner wall of the fixed block 41. The side walls of the two connecting frames 44 are fixedly connected to the side walls of the sliding plate 45. The inner walls of the two fixed blocks 41 are provided with special-shaped grooves 47. The liquid is transported into the special-shaped grooves 47 through the connecting hole 46 and finally enters the right side of the sliding plate 45 through the special-shaped grooves 47. Figure 6 As shown, when the spherical soft rod 25 returns to lift the arc extrusion plate 22, the connecting rod 42 will also rise, allowing the sliding plate 45 to return to its position and squeeze the hydraulic oil near the special-shaped groove 47. Due to the shape of the special-shaped groove 47, there are multiple branched serpentine channels, so that when the hydraulic oil in the connecting hole 46 enters the special-shaped groove 47, the liquid flows along the main channel and the fluid is almost unobstructed. However, when flowing in the opposite direction, the liquid will be guided into these complex branch channels. The shape of these channels makes the fluid flow encounter greater resistance, blocking the sliding plate 45 and slowing down the return speed of the sliding plate 45.

[0037] The expansion assembly 5 includes two fixed frames 51 fixedly connected to the side walls of the shell 1, the inner walls of the two fixed frames 51 are slidably connected with a transverse plate 52, and the side walls of the two transverse plates 52 are fixedly connected with a fixing rod 53.

[0038] The expansion assembly 5 also includes a fixing plate 54 fixedly connected to the outer wall of the connecting frame 44. The inner walls of the two fixing plates 54 are fixedly connected to the outer wall of the fixing rod 53. The inner walls of the two fixing frames 51 are connected with three gas pipes 55. When the connecting frame 44 is away from the fixing block 41, the fixing plate 54 will be driven to move, and the fixing rod 53 will move together, so that the transverse plate 52 will be away from the spherical soft rod 25. When the transverse plate 52 moves, it will squeeze the gas in the fixing frame 51.

[0039] The expansion assembly 5 also includes a connection frame 56 fixedly connected to the side wall of the fixed frame 51. The outer walls of the six air pipes 55 are connected to the inner wall of the rubber expansion block 13. The squeezed gas enters the rubber expansion block 13 through the air pipes 55, thereby expanding the rubber expansion block 13 to better fit the user's hand.

[0040] The expansion assembly 5 also includes a transverse plate 57 slidably connected to the inner wall of the connecting frame 56. The inner walls of the two transverse plates 57 are fixedly connected to the outer wall of the fixed rod 53. The bottoms of the two connecting frames 56 are connected with seven air outlet pipes 58. When the fixed rod 53 is moved together by the fixed plate 54, the fixed rod 53 will also drive the transverse plate 57 to move, allowing the transverse plate 57 to squeeze the gas in the connecting frame 56. The squeezed gas will be sprayed toward the hands of the user through the air outlet pipe 58.

[0041] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.

[0042] A specific application of this embodiment is as follows: when the present invention is used, the user holds the handle 12 and the rubber expansion block 13, and then presses the arc-surface extrusion plate 22 to descend, driving the spring plate 23 and the inclined friction block 231 to descend, so that the inclined surface of the inclined friction block 231 contacts the inclined surface of the inclined frame 21. At this time, the inclined friction block 231 will be squeezed, so that the spring plate 23 will retract into the arc-surface extrusion plate 22, so that the spring plate 23 accumulates resilience. At the same time, when the arc-surface extrusion plate 22 descends, the bottom of the arc-surface extrusion plate 22 The arc surface will contact the surface of the spherical soft rod 25, thereby squeezing the spherical soft rod 25 to move toward the fixing ring 31, and the spherical soft rod 25 will squeeze the clamping block 32, so that the clamping block 32 rotates, so that the four clamping blocks 32 are close to each other, and at the same time, the arc spring 33 is stretched to allow the arc spring 33 to accumulate resilience, so that the four clamping blocks 32 can clamp the diseased part. After the clamping is completed, the pressing on the arc surface squeezing plate 22 can be cancelled. Since the surface of the inclined friction block 231 is relatively rough and the friction force is large, due to the elastic force, the arc spring 33 is pressed against the lesion part. The rebound force of the spring plate 23 is smaller than the friction force, so the arc-surface extrusion plate 22 will stop, and the clamping force of the clamping block 32 will be adjusted again. When the clamping force needs to be increased, just press the arc-surface extrusion plate 22 again, and the spherical soft rod 25 will continue to be squeezed, thereby continuing to squeeze the clamping block 32, so that the clamping block 32 increases the clamping force. When the clamping force needs to be reduced, press the connecting plate 24 to retract the spring plate 23 into the arc-surface extrusion plate 22, so that the inclined friction block 231 is separated from the inclined frame 21. At this time, the arc The rebound force of the spring 33 will be released, allowing the clamping block 32 to return to its original position, and the side of the spherical soft rod 25 close to the clamping block 32 will be squeezed to allow the spherical soft rod 25 to return to its original position, so that the clamping blocks 32 are separated from each other, and the clamping force on the lesion part is weakened. At the same time, the spherical soft rod 25 will lift the arc surface squeezing plate 22. The size of the clamping force is controlled by the pressing depth of the arc surface squeezing plate 22, ensuring that the lesion part is accurately clamped. The clamping force can be quickly adjusted by pressing the arc surface squeezing plate 22 or squeezing the connecting plate 24.

[0043] Secondly, when the arc-surface extrusion plate 22 descends, it also drives the connecting rod 42 to descend, so that the connecting rod 42 drives the rotating frame 43 to rotate, and the rotating frame 43 tilts, thereby pushing the connecting frame 44 away from the connecting rod 42, and driving the sliding plate 45 to move. Since there is hydraulic oil inside the fixed block 41, when the sliding plate 45 moves, it will squeeze the hydraulic oil, and the squeezed hydraulic oil will enter the connecting hole 46, and be transported into the special-shaped groove 47 through the connecting hole 46, and finally enter the right side of the sliding plate 45 through the special-shaped groove 47, as shown in FIG. Figure 6As shown, when the spherical soft rod 25 returns to lift the arc-surface extrusion plate 22, the connecting rod 42 will also rise, allowing the sliding plate 45 to return to its position and squeeze the hydraulic oil near the special-shaped groove 47. Due to the shape of the special-shaped groove 47, there are multiple branched serpentine channels, so that when the hydraulic oil in the connecting hole 46 enters the special-shaped groove 47, the liquid flows along the main channel and the fluid is almost unobstructed. However, when flowing in the reverse direction, the liquid will be guided to these complex branch channels. The shape of these channels makes the fluid flow encounter greater resistance, blocking the sliding plate 45, slowing down the return speed of the sliding plate 45, thereby slowing down the return speed of the arc-surface extrusion plate 22, effectively preventing the arc spring 33 from rebounding too quickly, which may cause the clamping block 32 to separate a large distance, affecting the adjustment of the clamping force, and can more accurately adjust the required clamping force;

[0044] Secondly, when the connecting frame 44 is away from the fixing block 41, the fixing plate 54 will be driven to move, and the fixing rod 53 will move together, so that the transverse plate 1 52 will be away from the spherical soft rod 25. When the transverse plate 1 52 moves, the gas in the fixing frame 51 will be squeezed. The squeezed gas will enter the rubber expansion block 13 through the gas pipe 55, so that the rubber expansion block 13 will expand, better fit the user's hand, reduce the user's discomfort caused by holding the handle 12 for a long time, and effectively prevent the user from getting tired after holding it for a long time, which affects the control of the precise force of pressing the arc surface squeezing plate 22;

[0045] Secondly, when the fixed rod 53 is moved together with the fixed plate 54, the fixed rod 53 will also drive the transverse plate 2 57 to move, so that the transverse plate 2 57 squeezes the gas in the connecting frame 56, and the squeezed gas will be sprayed toward the user's hands through the outlet pipe 58. When the arc surface extrusion plate 22 is frequently pressed or the arc surface extrusion plate 22 is raised, the transverse plate 2 57 will frequently reciprocate on the inner wall of the connecting frame 56, and the outlet pipe 58 will frequently spray light gas toward the user's hands. The tiny airflow brought by the frequent light gas spray helps to relieve the tension or discomfort of the hand muscles.

[0046] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention.
