[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3The utility model provides a technical solution: a portable calculator, including a mounting plate 1, the interior of the mounting plate 1 is hollow, a mounting mechanism 2 is provided at the bottom of the mounting plate 1, a calculator body 3 is fixedly provided on the top of the mounting plate 1, and a receiver 4 is embedded on the top surface of one end of the calculator body 3.

[0024] The mounting mechanism 2 includes a wristband 201, and there are two wristbands 201. Connecting springs 202 are provided on both sides of the mounting plate 1. A movement rod 203 is provided at the bottom of the connecting spring 202. One end of the movement rod 203 extends to the interior of the mounting plate 1 and is movably connected to the mounting plate 1. A limiting rod 204 is provided below the movement rod 203. One end of the limiting rod 204 is in contact with the mounting plate 1. A connecting belt 205 is provided below the connecting spring 202. A hole 206 is provided on the top surface of the connecting belt 205. The limiting rod 204 passes through the hole 206 and is adapted to the hole 206. A positive Velcro 207 is provided on one side surface of one wristband 201, and a negative Velcro 208 is provided on one side surface of the other wristband 201.

[0025] The positive pole Velcro 207 is adhered to the negative pole Velcro 208 , and a fixing plate 209 is provided on the side of the connecting spring 202 away from the mounting plate 1 .

[0026] The fixing plates 209 are fixedly connected to the connecting springs 202 and the limiting rods 204 . A reinforcement plate 210 is provided on the front of the mounting plate 1 . There are two reinforcement plates 210 , and both reinforcement plates 210 are fixedly connected to the corresponding fixing plates 209 .

[0027] See also Figure 1-2 and 4, the cross-sectional shape of the reinforcing plate 210 is L-shaped, a groove 211 is provided on the surface of the reinforcing plate 210, a clamping plate 212 is provided on the front of the mounting plate 1, the clamping plate 212 is adapted to the groove 211, the clamping plate 212 is in contact with the reinforcing plate 210, and a mounting screw 213 is provided at the bottom end of the clamping plate 212, and the clamping plate 212 is fixedly connected to the mounting plate 1 through the mounting screw 213.

[0028] During operation, first place the mounting plate 1 on the wrist so that the calculator is located above the wrist, then operate the two wristbands 201 so that the two wristbands 201 are tied to the wrist and the two wristbands 201 are in contact with each other, and the operation of the wristbands 201 will make the positive Velcro 207 and the negative Velcro 208 in contact with each other. Since the positive Velcro 207 and the negative Velcro 208 are adhered to each other, the positive Velcro 207 and the negative Velcro 208 are fitted together, which can stably connect the two wristbands 201, improve stability, and make the calculator stably located on the wrist, and then move the two reinforcement plates 210 at the same time and in opposite directions. The plate 210 is fixedly connected to the fixed plate 209. The movement of the reinforcing plate 210 drives the movement of the fixed plate 209, so that the distance between the two fixed plates 209 is expanded, and the moving rod 203, the connecting spring 202 and the limiting rod 204 fixedly connected to the fixed plate 209 move at the same time. When the connecting spring 202 moves, the connecting spring 202 can be stretched, so that the length of the connecting spring 202 increases, and the connecting spring 202 is deformed. When the moving rod 203 moves, one end of the moving rod 203 is movably connected to the mounting plate 1, which ensures the movement of the moving rod 203, allowing the fixed plate 209 to move linearly. When the limiting rod 204 moves When the distance between the limiting rod 204 and the mounting plate 1 is expanded, the connecting belt 205 is operated to make the connecting belt 205 in a vertical state. The vertical state of the connecting belt 205 allows the hole 206 on the surface of the connecting belt 205 to be located on one side of the limiting rod 204. Then, the limiting rod 204 is automatically moved by the action of the connecting spring 202, so that the limiting rod 204 passes through the hole 206 on the surface of the connecting belt 205, allowing the limiting rod 204 to merge with the connecting belt 205, preventing the wristband 201 fixed to the connecting belt 205 from moving, thereby increasing stability, and The connecting spring 202 will also cause the reinforcing plate 210 to move automatically, so that the groove 211 on the surface of the reinforcing plate 210 is located on the back of the card plate 212. Then, the card plate 212 is merged with the groove 211, so that the card plate 212 and the two reinforcing plates 210 are in contact with each other. Then, the card plate 212 and the mounting plate 1 are fixed together by screws, which can prevent the two reinforcing plates 210 from moving and improve the stability of the connecting belt 205, so that the calculator can be stably placed on the wrist to prevent it from being lost and easy to carry. When using the computer, voice input can be performed through the earpiece 4, and the voice can be received by the microprocessor in the calculator, so that intelligent voice input can be performed.
