[0024] like Figure 2As shown, the adjustable leg support device 8 includes an electric push rod 801 and a bracket 804. When the electric push rod 801 is working, it drives the bracket 804 to adjust the angle. The electric push rod 801 is fixed to the outer wall of the support frame 6 by bolts. The power rod end of the electric push rod 801 is inserted into the inner wall of the support frame 6 and is slidably connected with the inner wall of the support frame 6. The power rod end of the electric push rod 801 is welded and fixed with a slider 802. The top of the slider 802 is rotatably connected to a support plate 803. The end of the support plate 803 away from the slider 802 is rotatably connected to the bottom of the bracket 804. The bottom of the bracket 804 is away from the support plate 803. One end is rotatably connected to a connecting rod 805, and the outer wall of the connecting rod 805 is slidably connected to the inner wall of the support frame 6. The electric push rod 801 is controlled to drive the slider 802 to slide in the inner wall of the support frame 6, and at the same time, the support plate 803 rotatably connected to the top of the slider 802 is driven to move, and the end of the support plate 803 away from the slider 802 is rotatably connected to the inner wall of the bracket 804, and the end of the bottom of the bracket 804 away from the support plate 803 is rotatably connected to the top of the connecting rod 805, so that the support plate 803 moves and drives the bracket 804 to rotate, thereby realizing the adjustment of the support angle of the bracket 804.
[0025] like Figure 2 As shown, a slide groove is provided at the position where the top of the support frame 6 is connected to the slider 802, and the inner wall of the slide groove is slidably connected to the outer wall of the slider 802, and the end of the support frame 6 close to the connecting rod 805 is rotatably connected to the second limit rod 806, and one end of the second limit rod 806 is inserted into the inner wall of the support frame 6 and threadedly connected to the inner wall of the support frame 6, and the connecting rod 805 is squeezed and limited by rotating the second limit rod 806 to prevent the connecting rod 805 from slipping during use, and the slider 802 and the support plate 803 are pushed to move by the electric push rod 801, and then the second limit rod 806 releases the limit on the connecting rod 805, so that the height of the bracket 804 can be adjusted in a small range.
[0026] like Figure 3 and Figure 4As shown, the moving device 14 includes a pedal 143 and a universal wheel 144. When the pedal 143 is moved by force, the universal wheel 144 is driven to rise and fall and contact the ground to achieve the purpose of movement. The moving device 14 also includes a telescopic sleeve 141. One end of the telescopic sleeve 141 is fixedly connected to the inner wall of the support column 13, and the other end is fixedly connected to the top of the pedal 143. A return spring 142 is slidably sleeved on the outer wall of the telescopic sleeve 141. One end of the return spring 142 is fixedly connected to the inner wall of the support column 13, and the other end is fixedly connected to the top of the pedal 143. The bottom of the pedal 143 is fixedly connected to the universal wheel 144. The inner wall of the pedal 143 is provided with a buffer spring 145, and one end of the buffer spring 145 is welded and fixed with a clamping block 146, and the clamping block 146 is fixedly connected to the bottom of the pedal 143. Block 146 is slidably connected to the inner wall of pedal 143. When pedal 143 is stepped on by foot, pedal 143 is forced to move downward, and universal wheel 144 is driven to move, so that universal wheel 144 contacts the ground. In the process of pedal 143 moving downward, block 146 is squeezed and limited by the inner wall of support column 13, so that block 146 shrinks in the inner wall of pedal 143 and squeezes buffer spring 145, so that the elastic potential energy of buffer spring 145 increases. When the position of block 146 moves to correspond to the slot opened on the inner wall of support column 13, the elastic potential energy of buffer spring 145 is used to send block 146 into the slot, and pedal 143 is fixed in the inner wall of support column 13. At this time, universal wheel 144 contacts the ground, which is convenient for moving the device.
[0027] like Figure 3 and Figure 4 As shown, a slot is provided at a position on the inner wall of the support column 13 corresponding to the block 146, and the inner wall of the slot is slidably connected to the outer wall of the block 146, and a push plate 147 is slidably connected to the outer wall of the support column 13 corresponding to the slot, and one end of the push plate 147 is inserted into the inner wall of the support column 13, and the block 146 is withdrawn from the inner wall of the support column 13 by pressing the push plate 147, and the pedal 143 and the universal wheel 144 are lifted by the elastic potential energy of the return spring 142 to break away from the contact with the ground, thereby maintaining the stability of the device.
[0028] like Figure 1 As shown, a limiting circular block is welded and fixed to the bottom of the support frame 6, and the diameter of the limiting circular block is larger than the diameter of the connection between the connecting plate 5 and the support frame 6, and a mounting plate 9 is welded and fixed to the end of the telescopic rod 2 away from the connecting plate 5, and a lifting plate 10 is slidably connected to the inner wall of the mounting plate 9, and a foot rest 11 is fixedly connected to the end of the lifting plate 10 away from the mounting plate 9, and a third limiting rod 12 is threadedly connected to the side wall of the mounting plate 9. The lifting plate 10 is limited by the third limiting rod 12, which facilitates the adjustment of the height of the lifting plate 10, and then the patient's feet are placed on the foot rest 11 to facilitate medical staff to perform surgery.
[0029] The working principle is that when in use, pedal 143 is stepped on with the foot, so that pedal 143 is forced to move downward, and universal wheel 144 is driven to move, so that universal wheel 144 contacts the ground. In the process of pedal 143 moving downward, the inner wall of support column 13 squeezes and limits block 146, so that block 146 shrinks in the inner wall of pedal 143 and squeezes buffer spring 145, so that the elastic potential energy of buffer spring 145 increases. When the position of block 146 moves to correspond to the slot provided on the inner wall of support column 13, the elastic potential energy of buffer spring 145 is used to send block 146 into the slot, and pedal 143 is fixed in the inner wall of support column 13. At this time, universal wheel 144 contacts the ground, and the position adjustment of the device can be achieved by only pushing the device. After the adjustment is to a suitable position, the block 146 is withdrawn from the inner wall of the support column 13 by pressing the push plate 147, and the pedal 143 and the universal wheel 144 are raised by using the elastic potential energy of the return spring 142 to break away from the contact with the ground and maintain the stability of the device. Then the electric push rod 801 is controlled to drive the slider 802 to slide in the inner wall of the support frame 6, and at the same time, the support plate 803 connected to the top of the slider 802 is driven to move, and the end of the support plate 803 away from the slider 802 is rotatably connected to the inner wall of the bracket 804, and the end of the bottom of the bracket 804 away from the support plate 803 is rotatably connected to the top of the connecting rod 805, so that the support plate 803 moves and the bracket 804 is driven to rotate at the same time, so as to adjust the support angle of the bracket 804 to better fit the patient's legs.
[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
