Side grooves 37 are opened inside the front and rear sides of the device body 1, and the adjustment rod 31 is rotatably connected inside the side grooves 37. The adjustment rod 31 passes through the left and right sides of the bottom groove 2, and the adjustment plate 33 is adapted to be placed inside the bottom groove 2. When the inclination angle of the device body 1 does not need to be adjusted, the adjustment plate 33 can be placed inside the bottom groove 2 without affecting the normal use of the device body 1. The front and rear ends of the device body 1 are provided with annular grooves 37. 8. Protective covers 39 are clamped at both the front and rear ends of the device body 1. The friction rod 36 and the annular groove 38 are adapted to be clamped. After the friction rod 36 is clamped inside the annular groove 38, the position of the adjustment rod 31 is limited, that is, the inclination angle of the device body 1 is limited at this time. The protective cover 39 is set on the end face of the adjustment rod 31 and the surface of the fixing ring 34. The protective cover 39 can shield the fixing ring 34 to prevent the operator from accidentally touching the fixing ring 34 and causing the inclination angle of the device body 1 to change. The combination of the pressure spring 35 and the friction rod 36 is distributed circumferentially on the surface of the fixing ring 34. The two ends of the connecting rod 41 are fixedly connected to the two adjacent friction rods 36 respectively. The end of the buffer spring 42 away from the connecting rod 41 is fixedly installed on the end face of the fixing ring 34. The operator can pull the connecting rod 41 to drive the friction rod 36 to move, so as to rotate the adjusting rod 31 to adjust the inclination of the device body 1.

[0028] Reference Figure 3 and Figure 6The position limiting component 5 includes a winding rod 51 rotatably connected to the inside of the device body 1, a pull rope 52 is wound around the surface of the winding rod 51, a slide groove 53 is provided at the top of the bottom groove 2, a slider 54 is slidably connected inside the slide groove 53, one end of the winding rod 51 is located outside the device body 1, and the other end of the winding rod 51 extends to the inside of the bottom groove 2, and one end of the pull rope 52 away from the winding rod 51 is fixedly connected to the surface of the slider 54, and the winding rod 51 is rotated to wind the pull rope 52, so that the pull rope 52 pulls The slider 54 slides inside the slide groove 53, and a push spring 55 is fixedly installed on the end face of the slider 54. A vertical rod 56 is fixedly installed on the bottom end of the slider 54, and a clamping wheel 1 57 is fixedly connected to the bottom end of the vertical rod 56. A clamping wheel 2 58 is fixedly installed on the surface of the adjusting rod 31. The end of the push spring 55 away from the slider 54 is fixedly installed on the inner wall of the slide groove 53. The clamping wheel 1 57 and the clamping wheel 2 58 are adapted to be clamped. The clamping wheel 1 57 is pushed to be clamped with the clamping wheel 2 58. At this time, the position of the adjusting rod 31 is limited.

[0029] Working principle: when the operator needs to adjust the inclination angle of the equipment body 1, the protective cover 39 can be removed first, and then the operator pulls the connecting rod 41 to compress the buffer spring 42. At this time, the connecting rod 41 will drive the fixedly connected friction rod 36 to move in the direction away from the annular groove 38. When the friction rod 36 is separated from the annular groove 38, the position of the adjusting rod 31 is no longer limited. Then the operator rotates the winding rod 51 to make the winding rod 51 wind up the pull rope 52. At this time, the pull rope 52 will pull the slider 54 to compress the push spring 55 inside the slide groove 53 to move. Then the slider 54 will drive the vertical rod 56 and the card wheel 1 57 to move, so that the card wheel 1 57 is separated from the card wheel 2 58. At this time, the adjusting rod 31 fixedly connected to the card wheel 2 58 can rotate. Then the operator rotates the adjusting rod 31. The adjusting rod 31 will drive the adjusting plate 33 to rotate through the fixedly connected connecting rod 32, and the equipment body 1 is pushed by the reaction when the adjusting plate 33 rotates, thereby adjusting the inclination angle of the equipment body 1.

[0030] When the adjustment is completed, the operator releases the connecting rod 41, and the connecting rod 41 pushes the friction rod 36 to move to the inside of the annular groove 38 under the action of the rebound force of the buffer spring 42. Then the operator releases the winding rod 51, so that the slider 54 drives the clamping wheel 1 57 to move under the action of the rebound force of the push spring 55, until the clamping wheel 1 57 and the clamping wheel 2 58 are engaged with each other. At this time, the position of the clamping wheel 2 58 is limited, and then the position of the adjustment rod 31 is limited, that is, at this time, the inclination angle of the equipment body 1 is fixed for the convenience of the operator.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
