[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figures 1 to 4 As shown, the utility model includes a machine body 1; the side wall of the machine body 1 is rotatably connected to the machine tool spindle 11; the side wall of the machine body 1 close to the machine tool spindle 11 is fixedly connected to a limit frame 12; the inner side wall of the limit frame 12 is fixedly connected to a plurality of groups of telescopic rods 13; the telescopic rods 13 are a pair of two, and there are four pairs in total; a pair of the telescopic rods 13 are symmetrically arranged; the ends of a pair of the telescopic rods 13 are fixedly connected to the same base 14; the side wall of the base 14 away from the telescopic rod 13 is fixedly connected to a first connecting rod 16; the first connecting rod 16 is rotatably connected to a pair of first limiting wheels 15; the first limiting wheels 15 are symmetrically arranged; the first limiting wheel 15 is in contact with the machine tool spindle 11; when working, the power supply of the machine tool spindle 11 is turned on first, at this time the machine tool spindle 11 starts to rotate, and when the machine tool spindle 11 rotates, it will automatically drive the first limiting wheel 15 to rotate Because a plurality of first limiting wheels 15 are evenly arranged along the side wall of the machine tool spindle 11, when the machine tool spindle 11 is working, the plurality of first limiting wheels 15 will limit the machine tool spindle 11 by themselves, so as to achieve the purpose of reducing the vibration of the machine tool spindle 11. At the same time, if the size of the machine tool spindle 11 changes, the machine tool spindle 11 can be re-fixed by adjusting the length of the telescopic rod 13. The setting of multiple sets of second limiting wheels 22 can effectively enhance the limiting effect of the entire device, effectively reduce the vibration of the machine tool spindle 11 when working due to incomplete limiting setting of the entire device, thereby causing the probability of inaccurate measured data, effectively improve the reliability of the entire device, and at the same time, the setting of multiple sets of telescopic rods 13 can effectively increase the spindle size that the entire device can adapt to, and effectively increase the available scenarios of the entire device.

[0025] Reference Figure 3 and Figure 4 As shown, the side wall of the base 14 of the utility model is fixedly connected to a pair of elastic plates 2; the elastic plates 2 are symmetrically arranged; the side wall of the elastic plate 2 is fixedly connected to a second connecting rod 21; the second connecting rod 21 is rotatably connected to a pair of second limiting wheels 22; the second limiting wheels 22 are symmetrically arranged; the second limiting wheels 22 are in contact with the machine tool spindle 11; when working, the elastic plate 2 can press the second limiting wheel 22 toward the machine tool spindle 11 according to its own elastic force, at this time, the second limiting wheel 22 will contact with the machine tool spindle 11 to achieve a better limiting effect, and the setting of the elastic plate 2 and the second limiting wheel 22 can further enhance the limiting effect of the entire device, further reduce the probability of inaccurate measured data caused by vibration of the machine tool spindle 11 when working, and at the same time, the setting of the elastic plate 2 can effectively make the second limiting wheel 22 fit with the machine tool spindle 11, further enhance the limiting ability of the entire device, and effectively improve the reliability of the entire device.

[0026] Reference Figure 2 and Figure 3 As shown, the base 14 of the utility model is rotatably connected to the position of the limit frame 12 with a screw rod 3; the screw rod 3 and the limit frame 12 are threadedly connected; when working, when a more secure limit is needed, the screw rod 3 can be screwed first, and then the base 14 is pressed down after the screw rod 3 is rotated. At this time, because the base 14 is fixedly connected with a pair of telescopic rods 13, the base 14 will only move downward and will not rotate. Then, after the first limiting wheel 15 is adjusted to the required position, the screw rod 3 can be stopped from rotating to achieve a more secure limiting effect. Through the setting of the screw rod 3, the limiting force of the first limiting wheel 15 on the machine tool spindle 11 can be effectively adjusted. At the same time, the screw rod 3 also effectively increases the spindle size that can be adapted to the device as a whole, further improving the overall usable scene range of the device.

[0027] Reference Figure 4 As shown, the elastic plate 2 of the utility model is fixedly connected to a hinge head 4 on the side wall near the screw rod 3; the hinge head 4 is hinged with a fixing rod 41; the base 14 is fixedly connected to a plurality of adjusting teeth 42 on the side wall near the elastic plate 2; the end of the fixing rod 41 is located between two adjusting teeth 42; when it is necessary to change the force of the second limiting wheel 22 limiting the position of the machine tool spindle 11 during operation, the fixing rod 41 can be removed from the adjusting teeth 42, and then the fixing rod 41 can be placed between the required adjusting teeth 42. The closer the adjusting teeth 42 are to the screw rod 3, the greater the fixing force. By setting the fixing rod 41 and the adjusting teeth 42, the probability of the elastic plate 2 itself being unable to deform reliably due to changes in the spindle size can be effectively reduced, thereby further improving the overall usable scene range of the device.

[0028] Reference Figure 4 As shown, a sealing leather case 5 is detachably mounted on the top of the base 14 of the utility model; a sponge 51 is detachably mounted on the inner wall of the sealing leather case 5; the sponge 51 is in contact with the screw rod 3; during operation, the pre-prepared lubricating oil is first added to the sponge 51 to soak it, and then when the screw rod 3 rotates, the sponge 51 will be squeezed so that the lubricating oil inside it adheres to the side wall of the screw rod 3, so as to achieve the effect of lubricating the screw rod 3, and at the same time, the sealing leather case 5 can play a sealing and isolating role by itself, so as to achieve the purpose of reducing the outflow of the lubricating oil to the outside. The provision of the sponge 51 can effectively reduce the probability of the screw rod 3 being difficult to use due to the attachment of external impurities. At the same time, the provision of the sealing leather case 5 can effectively reduce the probability of the lubricating oil soaked in the sponge 51 flowing out to the outside, causing the probability of other devices malfunctioning after being attached with the lubricating oil, thereby further improving the overall reliability of the device.

[0029] The inner wall of the limit frame 12 of the utility model is fixedly connected with a corrugated cover 6; the corrugated cover 6 is in contact with the machine tool spindle 11; when working, the corrugated cover 6 can play a role in reducing the entry of external impurities into the limit frame 12. The setting of the corrugated cover 6 can effectively reduce the probability of external impurities entering the limit frame 12, and effectively reduce the probability of the overall fixing effect of the device being reduced due to the attachment of external impurities to the device inside the limit frame 12. At the same time, it can also reduce the probability of the first limit wheel 15 and the second limit wheel 22 being scratched The surface of the machine tool spindle 11 when performing the fixing work is caused by the attachment of impurities to the first limit wheel 15 and the second limit wheel 22.

[0030] Reference Figure 2 and Figure 3 As shown, the end of the screw rod 3 of the utility model is fixedly connected with a handle 7; the handle 7 is arranged at a position away from the limit frame 12; when working, the handle 7 can automatically make the use of the screw rod 3 simpler, faster and more convenient. The setting of the handle 7 can make the use of the screw rod 3 simpler, faster and more convenient.

[0031] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
