It can also be seen that a hollow drill rod 10 is connected to the lower end of the swivel, and the threaded rod 9 extends into the cavity of the hollow drill rod 10 after passing through the swivel 23. A piston 20 is arranged in the cavity of the hollow drill rod, and the piston 20 is fixedly connected with the lower end of the screw rod 9. As shown in fig. 4, a guide key groove 25 is further provided on the side surface of the screw 9 in the axial direction, and a key 26 capable of extending into the guide key groove 25 is provided in the inner cavity of the rotator 23. Thus, the screw 9 and the rotating sleeve 23 can rotate integrally, but the screw 9 can slide axially relative to the rotating sleeve 23.
The tool starts the motor 2 by pressing the start-stop switch 1 and stops the motor 2 by pressing the start-stop switch 1. When the motor 2 is controlled to rotate, the motor rotating shaft 3 and the driving ring 4 rotate simultaneously (the motor rotating shaft rotates by connecting a hollow rotating cylinder 5, two ends of the hollow rotating cylinder 5 are installed in an inner cavity of the shell 7 through bearings or shaft sleeves 6, the driving ring 4 is fixed at the lower end of the hollow rotating cylinder 5), and components such as the relatively static component combination nut 8, the screw 9 and the hollow drill rod 10 are in a relatively static state (the combination nut 8) due to inertia, so that after the driving ring rotates relative to the combination nut 8, the rotating process (step 1 in fig. 7) enables an inclined plane 11 positioned on the inner wall of the driving ring to cross a radial pushing rod 12 of the combination nut 8, the radial pushing rod 12 is supported on a constraint step 13 (a baffle 14 is arranged on one side of the constraint step 13), and thus the combination nut 8 is in a compressed state, and can be meshed with external threads of the screw 9 after the combination nut 8 is compressed, as in the rotating 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 situ (the combined nut 8 is constrained in the driving ring 4, as shown in fig. 5 and 6, the inner wall of the driving ring comprises an annular groove 15, the inclined surface 11 and the constraint step 13 are respectively positioned in the annular groove 15, the outer ends of the radial push rods 12 are respectively positioned in the annular groove 15, in order to keep the radial push rods 12 to move outwards all the time, radial springs 40 are sleeved at the outer ends of the radial push rods to drive the radial push rods and the nut group pieces 17 of the combined nut to pop out radially outwards, the combined nut comprises a follow-up supporting ring 16, n radial perforations are uniformly distributed on the side wall of the follow-up supporting ring 16, the radial push rods 12 are matched and penetrate through the radial perforations and can slide freely, and the radial springs 40 are supported between the stop platforms at the tail ends of the follow-up supporting ring 16 and the radial push rods 12, and the screw rod 9 and the hollow drill rod 10 are not constrained, so that the combined nut 8 can rotate to drive the screw rod 9 and the hollow drill rod 10 to rotate.
The constraint button 18 capable of automatically ejecting is additionally arranged on the outer side of the root of the hollow drill rod, and after the constraint button is pressed, the annular expansion part 19 of the root of the hollow drill rod can be constrained, so that the rotation speed of the annular expansion part is reduced or the annular expansion part is not rotated any more, at the moment (the screw rod 9 and the hollow drill rod are not rotated and the combined nut 8 is rotated), the screw rod 9 is driven to move downwards when the combined nut 8 is rotated, and then the piston 20 is driven to extend forwards. When the screw rod 9 extends out to reach the limit position or the controlled position, the inner end of the constraint button rubs with the outer wall of the hollow drill rod to vibrate or make a click sound (the constraint button can be loosened before vibration or sound is made), and at the moment, after the constraint button 18 is loosened, the screw rod 9 and the hollow drill rod 10 continue to rotate along with the combined nut 8. Rotation of the hollow drill rod 10 enables it to be screwed into muscle tissue to a deep level when it contacts 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, so that the driving ring 4 stops suddenly, and the components of the combination nut 8, the screw 9, the hollow drill rod 10 and the like still rotate clockwise by a small angle due to inertia, as shown in the rotation process of (3) in fig. 7 (step 4 in fig. 12). When the combination nut 8 rotates clockwise and the drive ring 4 does not rotate, the radial push rod 12 of the combination nut 8 falls off the restriction step 13 on the inner wall of the drive ring 4, and returns to the automatic outward expansion state, so that the combination nut 8 is disengaged from the screw 9, and at this time, the unconstrained screw 9 carries the piston 20 together and is sprung upward by the thrust spring 21. In the process of the upward instant ejection of the piston 20, the deep quarantine sample of the muscle tissue is sucked through negative pressure, after the tool is pulled out, when the sample needs to be taken out, the motor 2 is started and the restraint 18 button is pressed, so that (as described above) the drive ring belt 4 drives the combination nut 8 to rotate, and the drive screw 9 and the piston 20 move forwards to push the sample out of a proper sample container. It can be seen that the manual selection of the appropriate sampling depth can be made by controlling the motor on and off and controlling the constraint knob.
Example 2: based on the control mode described above, another mode may be adopted in embodiment 1, in which an encoder is mounted on the motor shaft to detect a motor rotation speed change, the encoder transmits a motor rotation speed change signal to a signal input end of a controller, and the controller controls the motor to stop rotating according to the motor rotation speed change. Specifically, after detecting a sudden decrease in the motor rotation speed (a sudden increase in the coil current or detecting the motor rotation speed by the encoder) by the controller, the motor is controlled to stop. In this way, the restraint button is used in the same manner as described above, and is not repeated, except that when the hollow drill stem is subjected to resistance and the rotation speed is reduced or even no longer rotates after the hollow drill stem contacts the hard bone part, the screw rod integrally rotating with the hollow drill stem is also reduced or no longer rotates, the controller detects that the rotation resistance of the motor is large (the coil current suddenly increases), the control motor suddenly stops rotating to cause the driving ring to suddenly stop, and the assembly such as the combination nut, the screw rod and the hollow drill stem still rotates clockwise by a small angle due to inertia, and 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 that the combination nut is separated from engagement with the screw rod, and at the moment, the unconstrained screw rod carries the piston and is sprung up by the thrust spring.
Based on the above-mentioned form of this embodiment for the device can be in depth and be close to the bone part and take a sample, and the hollow drill rod front end is in depth near the bone position and is restrained by the bone and after the rotational speed slows or stops rotating, can be automatically through the quick quarantine sample that draws of piston near the bone position, thereby can obtain animal quarantine sample more accurately.
Example 3: based on the above embodiments 1 or 2, in case a continuous large number of samples are required, the above embodiments may be inconvenient to use, for example, the tool may require cleaning or even disinfection treatment for the operation requiring continuous sampling when deep sampling of animal-derived food is performed by the tool, because the previous sample contaminates the hollow drill rod lumen. And the tool also has the potential to bring new sources of contamination by secondary contact with air or to directly contaminate the air during removal of the sample to the sample container.
This embodiment is directed to the technical problem that may be faced, by matching and sleeving a sample tube 31 in the original hollow drill rod 10, installing the sample tube 31 from the root of the hollow drill rod, screwing the hollow drill rod out of the tool swivel 23 (pressing the constraint button 18 can prevent the swivel 23 from rotating, thereby facilitating screwing the hollow drill rod 10), inserting the sample tube into the cavity of the hollow drill rod from the rear end, and ensuring that the inner wall of the front end of the hollow drill rod is provided with an inner baffle 39 for constraining the sample tube to automatically slip.
Based on the design, the piston 29 can be matched and sleeved with the sample tube 31, and the lower end of the screw rod is connected with the piston and then penetrates into the sample tube.
Example 4: on the basis of embodiment 3, unlike embodiment 3, a sample piston 29 is installed in the sample tube, a baffle is arranged at the rear end of the sample tube 31, so that the sample piston is always positioned in the sample tube and cannot be separated (can be supported at the end part of an arc-shaped guide body 33), as shown in fig. 8 and 9, the rear end of the sample piston 29 also comprises a spherical traction end 30, the original piston is modified into a combined piston 27, the combined piston has a two-petal structure and can be automatically sprung out, the front ends of the two petals 28 are respectively provided with a clamping part, the diameter of the lower end of a design swivel is larger than that of the sample tube, the root part of a hollow drill rod is provided with an expansion section 34 with an inner diameter larger than that of the outer diameter of the sample tube, and the expansion section 34 is in threaded connection with the lower end of the swivel 23. Therefore, when the combined piston 27 is located at the expansion section, the clamping part at the front end of the combined piston 27 is automatically unfolded, and after the combined piston 27 penetrates into the inner wall of the sample tube 31, the clamping part at the front end of the combined piston 27 is supported by the arc-shaped guide body 33 (the arc-shaped guide body 33 is supported below the expansion section of the swivel) to be compressed and converged, and can be clamped at the traction end at the rear end of the sample piston, so that the combined piston drives the sample piston to stretch and retract.
Through this scheme for when the combination piston is followed the screw rod and is moved backward, can drive the sample piston and move backward, and then inhale the sample in the sample pipe, when the combination piston that keeps moving backward gets into hollow drill rod root expansion section, the combination piston releases the sample piston, at this moment, unscrews hollow drill rod, pulls out the sample pipe from the rear end, then makes its seal to sample pipe front end closing cap. Based on this embodiment, there may be multiple types of hollow drill pipes and sample tubes to be used in combination, as shown in fig. 11, a certain hollow drill pipe with different types and a corresponding multiple sample tubes are combined into a group, and when different animal source foods or different depths are sampled, the hollow drill pipes with different types are replaced. When the same hollow drill rod is used for continuous sampling, the hollow drill rod is dismounted, the corresponding sample tube is taken out, after the sample tube is sealed, the hollow drill rod is cleaned, the piston part is cleaned, a new sample tube is sleeved in the hollow drill rod, and after the piston is inserted into the new sample tube, the constraint switch is pressed, and the hollow drill rod is screwed on the rotator.
Example 5: on the basis of the above embodiments, a guide frame is installed on the side wall of the tool, and a guide tube along the axial direction is installed in the guide frame, as shown in fig. 10, the guide tube can be telescopically adjusted along the guide frame and locked, a limit switch is installed in the guide tube, and the triggering end of the limit switch is a supporting part positioned at the front end of the guide tube. When the tool is used, the position of the guide tube on the guide frame is adjusted according to the required sampling depth (accurate positioning is achieved through scales), and in the working process of the tool, after the hollow drill rod penetrates into animal muscle tissue for a certain depth, the supporting part at the front end of the guide tube is pressed, so that the limit switch provides a closing signal, and the motor is suddenly closed. The off signal may be a pressure signal supplied to the controller to control the motor to stop, or the off signal may be a pressure contact switch connected in series to a power line of the motor, and the motor stops rotating after the pressure contact switch is pressed.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and are in no way limiting of the invention. Accordingly, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the scope of the present invention. For example, in other structural designs of the casing, such as prismatic or other forms including a handle, the position layout of each switch or button is adjusted, the internal structure is modified to match with the storage battery, or other auxiliary components are added on the basis of the internal structure to change the internal structure. The constraint switch can also have other functions similar to magnetic control to realize damping, or can be replaced by a switch of a hoop type brake structure, and the like.
