DETAILED DESCRIPTION

[0020] 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.

[0021] Embodiment 1: A first cavity 2 is provided inside the base 1, a support slide bar 3 is installed inside the first cavity 2, a spring 14 is sleeved on the outer side of the support slide bar 3, a first slider 4 is sleeved on the outer side of the support slide bar 3, a second cavity 8 is provided on both sides inside the mounting platform 6, a screw rod 7 is installed inside the second cavity 8, a second slider 20 is sleeved on the outer side of the screw rod 7, the second slider 20 is meshed with the screw rod 7 through a threaded groove, a third cavity 9 is provided inside the mounting platform 6, a motor 10 is installed at one end of the mounting platform 6, and a first rotating shaft 1 is installed inside the third cavity 9 5 and a second rotating shaft 16, a belt 11 is installed between the first rotating shaft 15 and the second rotating shaft 16, one end of the first rotating shaft 15 is connected to one end of a screw rod 7, one end of the second rotating shaft 16 is connected to the output end of the motor 10, one end of the second rotating shaft 16 is connected to one end of a screw rod 7, the tops of the two second sliding blocks 20 extend out of the second cavity 8 respectively, and the tops of the two second sliding blocks 20 are installed with mounting plates 17, the output end of the electric push rod 5 is installed with a fixing plate 19, and the bottom of the fixing plate 19 is installed with a limiting block 18, and the limiting block 18 is used in conjunction with the limiting groove 21.

[0022] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotation of the output end of the motor 10 can drive the second rotating shaft 16 to rotate. When the second rotating shaft 16 rotates, it will simultaneously drive the screw rods 7 installed inside the two second cavities 8 to rotate. Since a second slider 20 is sleeved on the outer side of the two screw rods 7, when the screw rods 7 rotate, the second slider 20 will slide along the installation direction of the screw rods 7, and at the same time drive the mounting plate 17 installed on the top of the second slider 20 to slide. The extension of the output end of the electric push rod 5 can drive the limit block 18 to be inserted into the limit groove 21, thereby the ejection plate 2 3 is fixed, and as the mounting plate 17 moves backward, the ejection plate 23 can be driven to move backward. Since the bottom of the ejection plate 23 is slidably sleeved on the outer side of the supporting slide bar 3 through the first slide block 4, when the ejection plate 23 moves backward, the first slide block 4 will slide along the installation direction of the supporting slide bar 3, thereby squeezing the spring 14 installed on the outer side of the supporting slide bar 3. Through this device, the ejection device can be automatically compressed and stored, and the manual power storage operation is abandoned. In addition, the ejection device will not automatically eject during the power storage process, thereby ensuring the stability of the ejection device.

[0023] Embodiment 2: Two fixing rods 12 are respectively installed on both sides of the top of the base 1, and the top of the fixing rods 12 is connected to the bottom of the mounting platform 6, four foot pads 13 are installed on the bottom of the base 1, and the four foot pads 13 are respectively located at the four corners of the bottom of the base 1, the top of the first slider 4 extends out of the first cavity 2, and an ejection plate 23 is installed on the top of the first slider 4, an ejection slot 22 is installed on one side of the ejection plate 23, and a limiting slot 21 is provided on the top of the ejection plate 23, an electric push rod 5 is installed on the top of the mounting plate 17, and the output end of the electric push rod 5 passes through the interior of the mounting plate 17.

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mounting platform 6 can be fixed above the base 1 by the fixing rod 12, and the whole device can be stably placed on the operating table by the foot pads 13 installed at the four corners of the bottom of the base 1. Since an ejection groove 22 is installed on one side of the ejection plate 23, the object to be ejected can be placed inside the ejection plate 23 and ejected through the ejection groove 22 to prevent the object from slipping halfway during the ejection process. Since a limiting groove 21 is provided on the top of the ejection plate 23, the ejection plate 23 can be fixed by the limiting groove 21 so that the entire ejection plate 23 can be ejected by accumulating force.

[0025] Working principle: When in use, the fixed plate 19 is pushed downward by extending the output end of the electric push rod 5, so that the limit block 18 installed at the bottom of the fixed plate 19 is inserted into the inside of the limit groove 21, and then the second rotating shaft 16 can be driven to rotate by the rotation of the output end of the motor 10. When the second rotating shaft 16 rotates, it will simultaneously drive the screw rods 7 installed inside the two second cavities 8 to rotate. Since a second slider 20 is provided on the outer side of the two screw rods 7, when the screw rods 7 rotate, the second slider 20 will slide along the installation direction of the screw rods 7, and at the same time drive the mounting plate 17 installed on the top of the second slider 20 to slide. When the mounting plate 17 moves, it will drive the entire elastic The ejection plate 23 moves. Since an ejection slot 22 is installed on one side of the ejection plate 23, the object to be ejected can be placed inside the ejection slot 22. Since the bottom of the ejection plate 23 is slidably sleeved on the outside of the supporting slide bar 3 through the first slider 4, when the ejection plate 23 moves backward, the first slider 4 will slide along the installation direction of the supporting slide bar 3, thereby squeezing the spring 14 installed on the outside of the supporting slide bar 3. After the ejection plate 23 moves to the specified position, the limit block 18 can be pulled out from the inside of the limit slot 21 through the contraction of the output end of the electric push rod 5, and then the ejection plate 23 will be ejected by the elastic force of the spring 14, thereby ejecting the object placed in the ejection slot 22.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
