Thus, the screw 9 and the sleeve 23 can rotate integrally, but the screw 9 can slide axially relative to the sleeve 23.
The tool enables the motor 2 to start and work by pressing the start-stop switch 1, and enables the motor 2 to stop working by pressing the start-stop switch 1. When the motor 2 is controlled to rotate, the motor shaft 3 and the driving ring 4 rotate simultaneously (the motor shaft rotates by connecting a hollow rotary cylinder 5, two ends of the hollow rotary cylinder 5 are installed in an inner cavity of a housing 7 through bearings or shaft sleeves 6, the driving ring 4 is fixed at the lower end of the hollow rotary cylinder 5), and the components which are relatively static are in a relatively static state (a combination nut 8) due to inertia, such as a combination nut 8, a screw 9, a hollow drill rod 10 and the like, so that after the driving ring 8 rotates relative to the combination nut 8, as shown in fig. 7
The inclined surface 11 on the inner wall of the driving ring 8 crosses over the radial push rod 12 of the combined nut 8, the radial push rod 12 is supported on the restraining step 13 on the inner wall of the driving ring (the side of the restraining step 13 is provided with a baffle 14), so that the combined nut is in a compressed state, and the combined nut 8 can be meshed with the external thread of the screw 9 after being compressed, as shown in the step 1 in fig. 7
The rotation process (step 2 and step 3 in fig. 12). At this time, the motor rotates to drive the driving ring 4 to rotate and further drive the combined nut 8 to rotate in place (the combined nut 8 is constrained in the driving ring 4, as shown in the figure5 and 6, the inner wall of the driving ring comprises an annular groove 15, the inclined surface 11 and the restraining step 13 are respectively positioned in the annular groove 15, the outer end of each radial push rod 12 is respectively positioned in the annular groove 15, and in order to keep each radial push rod 12 moving outwards all the time, a radial spring 40 can be sleeved at the outer end of each radial push rod to drive each radial push rod and each nut group piece 17 of the combined nut to pop out outwards in the radial direction. The combined nut comprises a follow-up support ring 16, n radial through holes are uniformly distributed in the side wall of the follow-up support ring 16, each radial push rod 12 penetrates through each radial through hole in a matching mode and can freely slide, and the radial spring 40 is supported between the follow-up support ring 16 and a blocking table at the tail end of each radial push rod 12), so that the screw rod 9 and the hollow drill rod 10 can be driven to rotate by the rotation of the combined nut 8 because the screw rod 9 and the hollow drill rod 10 are not constrained.
The outer side of the root of the hollow drill rod is additionally provided with a constraint button 18 capable of automatically popping out, and after the constraint button is pressed, an annular expansion part 19 at the root of the hollow drill rod can be constrained to slow down or stop rotating, at the moment (the screw rod 9 and the hollow drill rod do not rotate and the combination nut 8 rotates), so that the screw rod 9 is driven to move downwards when the combination nut 8 rotates, and then the piston 20 is driven to extend forwards. When the screw 9 extends to the limit position or the controlled position, the inner end of the restraint button generates friction with the outer wall of the hollow drill rod to vibrate or generate clicking sound (the restraint button can also be released before the vibration or sound is generated), and at the moment, after the restraint button 18 is released, the screw 9 and the hollow drill rod 10 continue to rotate together with the combined nut 8. The rotation of the hollow drill rod 10 enables it to be screwed into the muscle tissue to a deep level when it contacts the food of animal origin. At any time, the start-stop switch 1 is manually controlled according to the rotation depth of the hollow drill rod, the motor is turned off, the motor is controlled to stop suddenly to cause the driving ring 4 to stop suddenly, and the components such as the combined nut 8, the screw 9 and the hollow drill rod 10 still rotate clockwise by a small angle due to inertia, as shown in fig. 7
The rotation process (step 4 in fig. 12). When the combination nut 8 is rotated clockwise and the drive ring 4 is not rotated, the diameter of the combination nut 8The push rod 12 falls off the restraining step 13 on the inner wall of the drive ring 4 to return to the self-expanding outward state, so that the combination nut 8 is disengaged from the screw 9, and at this time, the screw 8 which is not restrained carries the piston 20 together and is sprung upward by the thrust spring 21. When the tool is pulled out and a sample needs to be taken out, the motor 2 is started and the restraint 18 button is pressed, so that the driving ring belt 4 moves the combined nut 8 to rotate, the screw rod 9 and the piston 20 are driven to move forwards, and the sample is pushed out into a proper sample container. Therefore, the proper sampling depth can be manually selected by controlling the starting and stopping of the motor and controlling the constraint knob.
Example 2: on the basis of the embodiment 1, based on the above control mode, another mode can be adopted, wherein an encoder is installed on the motor rotating shaft and used for detecting the change of the motor rotating speed, the encoder transmits a motor rotating speed change signal to the signal input end of the controller, and the controller controls the motor to stop rotating according to the change of the motor rotating speed. Specifically, after the motor speed is detected to suddenly decrease by the controller (the coil current is suddenly increased or the motor speed is detected by the encoder), the motor is controlled to stop. When the mode is adopted, the use mode of the restraint button is the same as that described above, and is not repeated, except that after the hollow drill bit is contacted with the hard bone part, the hollow drill rod is subjected to resistance and the rotating speed is reduced or even is not rotated any more, so that the rotating speed of the screw rod which integrally rotates with the hollow drill rod is reduced or is not rotated any more, the controller detects that the rotating resistance of the motor is larger (the coil current is increased suddenly), the motor is controlled to stop rotating suddenly to cause the sudden stop of the driving ring, the components such as the combination nut, the screw rod, the hollow drill rod and the like still rotate clockwise by a small angle due to inertia, under the condition that the combination nut rotates clockwise and the driving ring does not rotate, the radial push rod of the combination nut falls off the restraint step on the inner wall of the driving ring so as to return to an automatic outward expansion state, so that, is sprung up by the thrust spring.
Based on the above form of this embodiment for the device can go deep into and be close to the sclerotin part and take a sample, and the hollow drill rod front end is gone deep into near sclerotin position and is retrained by the sclerotin and after the rotational speed slows down or stop rotating, can draw the quarantine sample that is located near the sclerotin position fast through the piston automatically, thereby can obtain the animal quarantine sample more accurately.
Example 3: based on the above embodiment 1 or 2, in the case that a large number of samples need to be continuously collected, the above embodiment may have inconvenience in use, for example, when the tool is used for deep sampling of animal-derived food, for the operation process requiring continuous sampling, the tool may need to be cleaned or even sterilized because the previous sample pollutes the inner cavity of the hollow drill rod. And the tool also presents the possibility of a new source of contamination by secondary contact with air, or direct contamination of the air, during the removal of the sample into the sample container.
Aiming at the technical problem which may be faced by the present embodiment, a sample tube 31 is fittingly sleeved in the original hollow drill rod 10, the sample tube 31 is installed from the root of the air drill rod, after the hollow drill rod is screwed and separated from the tool swivel 23 (the swivel 23 can be prevented from rotating by pressing the restraint button 18, so as to facilitate screwing the hollow drill rod 10), the sample tube is inserted into the inner cavity of the air drill rod from the rear end, and it is ensured that the inner wall of the front end of the hollow drill rod is provided with an inner abutment 39 which restrains the sample tube from automatically slipping.
Based on the design, the piston 29 and the sample tube 31 can be sleeved in a matching way, and the lower end of the screw rod is connected with the piston and then extends into the sample tube.
