[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] Reference Figure 1-Figure 3The utility model provides an embodiment: a multi-directional fixing device for a residual limb model, comprising a chassis 1, an adjusting mechanism 2 is arranged on the upper side of the chassis 1, a servo motor 11 is fixedly connected to the inner bottom wall of the chassis 1, a turntable 13 is fixedly connected to the output end of the servo motor 11, support plates 3 are fixedly connected to both sides of the top wall of the turntable 13, a servo motor 1 4 is fixedly connected to the side wall of one side support plate 3, a rotating rod 5 is fixedly connected to the output end of the servo motor 1 4 through the support plate 3, a rotating rod 5 is fixedly connected to the output end of the servo motor 1 4, a slot 6 is provided on the upper and lower sides of the outer circumference of the rotating rod 5, and a transmission shaft 14 is slidably connected to both ends of the rotating rod 5 through the slot 6, The two transmission shafts 14 are rotatably connected to the moving plates 7 at the ends away from each other, and the two moving plates 7 are sleeved on the outer peripheries of the two ends of the rotating rod 5.

The middle parts of the two transmission shafts 2 15 are fixedly connected to the connecting plates 10; the outer periphery of the rotating disk 13 is fixedly connected to the limiting ring 12, and the limiting ring 12 is rotatably connected to the inside of the chassis 1; the two transmission shafts 2 15 are rotatably connected to the moving plates 7, and the ends of the transmission shafts 14 and 2 15 on both sides that are close to each other are fixedly connected to the limiting disks 8;
[0038] Specifically, after the residual limb model is fixed, the turntable 13 connected to the output end can be driven to rotate by starting the servo motor 11. When the turntable 13 rotates, the clamped residual limb model can be driven to rotate horizontally. When the turntable 13 rotates, the limit ring 12 connected to the periphery will also be driven to rotate. Since the limit ring 12 rotates inside the chassis 1, the chassis 1 will limit the limit ring 12, so the turntable 13 can be limited. Thus, the stability of the rotation of the turntable 13 is ensured to prevent it from detaching from the chassis 1. By starting the servo motor 4, the connected rotating rod 5 can be driven to rotate. Since the outer periphery of the rotating rod 5 is provided with a card slot 6, and the transmission shaft 14 It is engaged in the slot 6, so when the rotating rod 5 rotates, it can drive the transmission shaft 14 connected at both ends of the rotating rod 5 to rotate; when the transmission shaft 14 rotates, it can drive the peripheral transmission belt 9 to move, so that the transmission shaft 2 15 can be driven to rotate through the transmission belt 9; and the transmission belt 9 can be limited by the limiting plate 8 arranged on the transmission shaft 14 and the transmission shaft 2 15, so as to prevent the transmission belt 9 from falling off; when the transmission shaft 2 15 rotates, it can drive the corresponding connected connecting plates 10 to rotate at the same time, so that the fixed residual limb model can be flipped vertically, so that the staff can adjust the fixed residual limb model in all directions.
[0039] Reference Figure 1-Figure 3, the adjusting mechanism 2 includes a slide groove 201, and the two slide grooves 201 are both opened on both sides of the top wall of the turntable 13. The lower parts of the two moving plates 7 penetrate the slide groove 201 and are slidably connected to the inner wall of the turntable 13. A bidirectional screw 202 is rotatably connected to one side of the outer circumference of the turntable 13. One end of the bidirectional screw 202 penetrates the inner wall of the turntable 13 and is threadedly connected to the two moving plates 7. The upper and lower walls of the two connecting plates 10 are rotatably connected with threaded rods 207. The two threaded rods 207 penetrate the inner wall of the connecting plate 10. The upper and lower threads of the two threaded rods 207 are opposite. The upper and lower parts of the two threaded rods 207 are threadedly connected with the moving block 206; the front and rear sides of the plurality of threaded rods 207 are provided with a limiting rod 209, and the upper and lower ends of the plurality of limiting rods 209 penetrate the moving block 206 and are fixedly connected to the inner wall of the connecting plate 10; the front and rear sides of the bidirectional screw 202 are provided with a limiting rod 1 203, and both ends of the two limiting rods 1 203 penetrate the moving plate 7 and are fixedly connected to the inner wall of the turntable 13;
[0040] Specifically, by rotating the correspondingly connected threaded rod 207, the correspondingly connected moving block 206 can be driven to move; since the front and rear sides of the moving block 206 are penetrated by the limiting rod 209, the moving block 206 can be limited by the limiting rod 209, so that the moving block 206 can be moved up and down along the threaded rod 207, so that the position of the moving block 206 can be adjusted according to the shape of the residual limb model to be fixed; then, by rotating the bidirectional screw 202, the moving plates 7 connected at both ends can be driven to move. Since the moving plate 7 is also limited by the limiting rod 203, the moving plate 7 cannot rotate with the rotation of the bidirectional screw 202; therefore, when the bidirectional screw 202 rotates, it can drive the moving plates 7 connected at both ends to move closer or farther away at the same time. When the two moving plates 7 are close to each other, the residual limb model can be clamped and fixed, thereby achieving the effect of fixing residual limb models of different specifications.
[0041] Reference Figure 1-Figure 3 The inner walls of the front and rear sides of the multiple moving blocks 206 are rotatably connected to the rotating shaft 210, the outer peripheries of the middle parts of the multiple rotating shafts 210 are fixedly connected to the clamping blocks 205, the upper and lower walls of the multiple clamping blocks 205 are fixedly connected to one end of the torsion spring 204, and the other ends of the multiple torsion springs 204 are fixedly connected to the inner wall of the moving block 206;
[0042] Specifically, when the moving blocks 206 on both sides approach each other, the residual limb model will be clamped by the clamping block 205; when the clamping block 205 squeezes the residual limb model, the clamping block 205 will rotate around the rotating shaft 210, and when the clamping block 205 rotates, it will pull the corresponding connected torsion spring 204, so under the action of the torsion spring 204, the clamping block 205 can be driven to clamp and fix the residual limb model, thereby ensuring the stability of the clamping.
[0043] Reference Figure 1-Figure 3, the upper and lower ends of the two threaded rods 207 are fixedly connected with knobs 208;
[0044] Specifically, by providing knobs 208 at the upper and lower ends of the threaded rod 207 , it is convenient for a worker to rotate the threaded rod 207 to drive the moving block 206 to move.
[0045] Working principle: In actual use, by starting the servo motor 2 11, the connecting turntable 13 can be driven to rotate, thereby driving the clamped residual limb model to rotate; by starting the servo motor 14, the connected rotating rod 5 can be driven to rotate and the transmission shaft 14 can be driven to rotate through the slot 6, thereby driving the transmission shaft 2 15 to rotate through the transmission belt 9; and then the connecting plates 10 connected on both sides can be driven to rotate at the same time, so that the fixed residual limb model can be flipped, so that it is convenient for the staff to adjust the fixed residual limb model in multiple directions; in addition, by rotating the correspondingly connected threaded rod 207, the connected moving block 206 can be driven to move, so that the moving block 206 can be adjusted according to the shape of the residual limb model to be fixed; and then by rotating the bidirectional screw 202, the moving plates 7 connected at both ends can be driven to approach or move away at the same time. When the two moving plates 7 are close to each other, the residual limb model can be clamped and fixed, thereby achieving the effect of fixing residual limb models of different specifications.
