DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0029] Reference Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a tubular resin conveyor, comprising a mounting tube 2, a pushing member 3 and a driving device 1; one end of the mounting tube 2 is detachably connected to the driving device 1, the interior of the mounting tube 2 is provided with a mounting channel 21 for mounting a resin syringe, and the telescopic end 11 of the driving device 1 can move in the mounting channel 21 along the extension direction of the mounting channel 21; a connecting portion and a transmission thread 22 are provided on the inner wall of the mounting channel 21, and the transmission thread 22 is located on the side of the connecting portion close to the driving device 1, the connecting portion is used to connect with the injection barrel 41 of the resin syringe in the mounting channel 21, the pushing member 3 is installed in the mounting channel 21, and is threadedly connected with the transmission thread 22, one side of the pushing member 3 is connected to the threaded rod 42 of the resin syringe, and the other side abuts against the telescopic end 11.

[0030] Specifically, resin is a commonly used filling material in dentistry. Usually, the resin is stored in a syringe. The syringe storing the resin includes a syringe 41 and a threaded rod 42. The interior of the syringe 41 is hollow. One end of the syringe 41 is an injection head with an opening, and the other end is threadedly connected to the threaded rod 42. The resin is stored in the syringe 41. The threaded rod 42 rotates relative to the syringe 41, so that the threaded rod 42 moves toward the injection head under the action of the thread, so that the threaded rod 42 squeezes the resin inside the syringe 41, and the resin is squeezed out of the syringe 41 from the injection head under the push of the threaded rod 42; since the amount of resin required for each filling is small, the resin squeezed out of the syringe 41 will solidify, so the thread of the threaded rod 42 can accurately control the moving distance of the threaded rod 42, thereby accurately controlling the amount of the base resin. However, since the syringe 41 needs to remain stationary when the threaded rod 42 is rotated, the operation of extruding the resin can be realized by moving the threaded rod 42 toward the syringe 41 while rotating. Therefore, the operation of rotating the threaded rod 42 to extrude the resin requires both hands, which affects the doctor's treatment operation, while the nurse's help in squeezing out the resin will waste manpower and it is difficult to determine whether the amount of extruded resin meets the treatment needs.

[0031] The above-mentioned mounting tube 2 is a hollow tube structure, and the space inside the mounting tube 2 is used as the mounting channel 21. The mounting channel 21 is a cylindrical channel, and the mounting channel 21 penetrates the mounting tube 2 along the length direction of the mounting tube 2, that is, the mounting channel 21 extends along the length direction of the mounting tube 2. It is possible to select that a buckle is provided at one end of the mounting tube 2, a slot is provided on the driving device 1, and the mounting tube 2 abuts against the driving device 1 so that the buckle and the slot are connected by snapping; of course, it is also possible to select that a mounting hole is provided on the side wall of one end of the mounting tube 2, a boss is provided on the driving device 1, the telescopic end is arranged on the boss, the mounting tube 2 is sleeved on the boss, a screw hole is provided on the side of the boss, and a bolt is passed through the mounting hole and threadedly connected with the screw hole of the boss, so that the mounting tube 2 can be detachably connected to the driving device 1.

[0032] The thread lead angle of the above-mentioned transmission thread 22 is greater than the equivalent friction angle of the helical pair, that is, the transmission thread 22 is a non-self-locking thread. When the push member 3 is driven along the extension direction of the installation channel 21, the threaded connection between the push member 3 and the transmission thread 22 will not self-lock, so that the push member 3 can rotate under the action of the transmission thread 22.

[0033] The above-mentioned connecting part can be selected as a claw or a buckle arranged on the inner wall of the installation channel 21. The claw or the buckle is located at the end of the installation channel 21 away from the driving device 1. When the injection barrel 41 is located in the installation channel 21, the claw or the buckle is connected with the injection barrel 41 by clamping, so that the injection barrel 41 cannot rotate in the installation channel 21; of course, a rubber ring can also be selected as the connecting part. When the resin is injected into the installation channel 21, the rubber ring is elastically deformed and the resin injector can move in the installation channel 21 to the position where the threaded rod 42 is connected to the pushing member 3. At this time, the rubber ring abuts against the outer side surface of the injection barrel 41 of the resin injector, and the injection barrel 41 maintains a stable position in the installation channel 21 through friction.

[0034] The push member 3 can be a cylindrical structural member, and a thread matching the transmission thread 22 is arranged on the outer surface of the push member 3, so that the push member 3 is threadedly connected with the transmission thread 22 after being arranged in the installation channel 21. When the telescopic end 11 drives the push member 3 to move along the extension direction of the installation channel 21, the push member 3 rotates under the action of the thread when moving along the extension direction of the installation channel 21. The threaded rod 42 is connected to the push member 3, so that the rotation of the push member 3 drives the threaded rod 42 to rotate, so as to realize the operation of extruding the resin from the injection barrel 41. Of course, the push member 3 can also be selected as a circular sheet structure, and the thickness of the push member 3 is equal to the pitch of the transmission thread 22, so that the edge of the push member 3 can be inserted into the transmission thread 22, so that the push member 3 is threadedly connected with the transmission thread 22.

[0035] The above-mentioned resin syringe can select the end of the channel mounting channel 21 away from the driving device 1 to be inserted into the mounting channel 21, and the pushing piece 3 is set in the mounting channel 21. During the insertion process of the resin syringe, the threaded rod 42 is first inserted into the mounting channel 21, and then as the resin syringe moves, the injection barrel 41 enters the mounting channel 21. The resin syringe stops moving when the threaded rod 42 is inserted and connected with the pushing piece 3. At this time, the connecting part is connected to the injection barrel 41, and the resin syringe is installed in the mounting channel 21; of course, the mounting tube 2 can also be separated from the driving device 1, and the pushing piece 3 is separated from the mounting tube 2. The resin syringe is first inserted into the mounting channel 21 from the end of the mounting tube 2 used for connecting with the driving device 1, and the injection barrel 41 is first inserted into the mounting channel 21. As the resin syringe moves, the threaded rod 42 enters the mounting channel 21. After the injection barrel 41 is connected to the connecting part, the pushing piece 3 is inserted into the mounting channel 21 and connected to the threaded rod 42, and the pushing piece 3 is threadedly connected to the transmission thread 22.

[0036] The driving device 1 can be a motor, which has an output rod that can move linearly relative to the motor as a telescopic end. Of course, the driving device 1 can also be a telescopic cylinder. A groove can be set on the side of the pusher 3 facing the threaded rod 42, so that the end of the threaded rod 42 can be inserted into the groove, so that when the pusher 3 rotates, the side wall of the groove drives the threaded rod 42 to rotate. Of course, a buckle can also be set on the side of the pusher 3 facing the threaded rod 42, and the end of the threaded rod 42 can be engaged with the buckle, so that when the pusher 3 rotates, the threaded rod 42 is driven to rotate.

[0037] When the tubular resin delivery device provided by the embodiment of the present disclosure is used, the resin syringe is inserted into the installation channel 21, the injection barrel 41 is connected to the connecting part, the push piece 3 is arranged in the installation channel 21 and is threadedly connected to the transmission thread 22, and the push piece 3 is connected to the threaded rod 42, and the installation tube 2 installed with the push piece 3 and the resin syringe is detachably connected to the driving device 1; the driving device 1 is started, so that the telescopic end 11 extends out of the driving device 1 along the extension direction of the installation channel 21, and the telescopic end 11 pushes the push piece 3 to move in the direction away from the driving device 1, and the push piece 3 rotates under the action of the transmission thread 22, and the push piece 3 rotates to drive the threaded rod 42 to rotate and squeeze out the resin in the injection barrel 41, and the extruded resin is exposed at the end of the installation channel 21 away from the driving device 1, and the doctor takes the extruded resin to fill the defective part of the patient's tooth.

[0038] The tubular resin conveyor provided by the embodiment of the present disclosure includes a mounting tube 2, a pushing member 3 and a driving device 1; one end of the mounting tube 2 is detachably connected to the driving device 1, the interior of the mounting tube 2 is provided with a mounting channel 21 for mounting a resin syringe, and the telescopic end 11 of the driving device 1 can move in the mounting channel 21 along the extension direction of the mounting channel 21; a connecting portion and a transmission thread 22 are provided on the inner wall of the mounting channel 21, and the transmission thread 22 is located on the side of the connecting portion close to the driving device 1, the connecting portion is used to connect with the injection barrel 41 of the resin syringe in the mounting channel 21 to limit the movement of the injection barrel 41, the pushing member 3 is installed in the mounting channel 21, and connected with the transmission thread 2 2 threaded connection, so that the push member 3 can rotate under the action of the transmission thread 22 when it moves along the installation channel 21, one side of the push member 3 is connected to the threaded rod 42 of the resin syringe, and the other side is in contact with the telescopic end 11, so that the telescopic end 11 of the driving device 1 pushes the push member 3 to move, and the push member 3 rotates under the action of the transmission thread 22 when it moves, so that the push member 3 drives the threaded rod 42 to rotate and extrude the resin, so that the user can complete the operation of extruding the resin from the injection barrel 41 by controlling the driving device 1, avoiding the user using both hands to complete the operation of extruding the resin or requiring the help of others to extrude the resin, thereby improving the convenience of the operation of extruding the resin from the resin syringe.

[0039] Reference Figure 1 and Figure 2 As shown, the connection portion includes an abutment member 23; the abutment member 23 is arranged on the inner wall of the installation channel 21, and the abutment member extends along the circumference of the installation channel 21. The side of the abutment member 23 away from the inner wall of the installation channel 21 is used to abut against the outer side of the injection barrel 41 of the resin injector to limit the movement of the injection barrel 41 of the resin injector relative to the installation tube 2. In this way, the abutment member can limit the movement of the injection barrel 41 relative to the installation tube 2, and prevent the injection barrel 41 from rotating when the threaded rod 42 rotates, thereby ensuring that when the pusher 3 moves and drives the threaded rod 42 to rotate, the threaded rod 42 is in a state of moving relative to the injection barrel 41 to extrude the resin.

[0040] Specifically, the abutment 23 can be selected to be an annular structure, the axial direction of the annular structure is consistent with the extension direction of the installation channel 21, the outer side of the annular structure is at a lower level than the inner wall of the installation channel 21, and the inner side of the annular structure is used to abut against the injection barrel 41, so that the relative position between the injection barrel 41 and the annular structure is maintained stable through friction.

[0041] Of course, the abutment member 23 can also be selected to include two sub-abutments, and the two sub-abutments are arranged with a columnar or block structure relatively along the radial direction of the mounting tube 2, and the ends of the two sub-abutments close to each other are used to abut against the injection barrel 41. Of course, the abutment member 23 can also include multiple sub-abutments, and the multiple sub-abutments are arranged at intervals along the circumference of the mounting tube 2, and the ends of the multiple sub-abutments away from the inner wall of the mounting channel 21 are used to abut against the injection barrel 41.

[0042] Reference Figure 1 and Figure 2 As shown, in some embodiments, the abutment member 23 includes an annular body 231 and an elastic member 232, the annular body 231 is connected to the inner wall of the installation channel 21, the axial direction of the annular body 231 is consistent with the extension direction of the installation channel 21, the elastic member 232 is connected to the side of the annular body 231 away from the inner wall of the installation channel 21, and the elastic member 232 abuts against the outer side of the injection barrel 41. In this way, the elastic member 232 can be deformed to adapt to injection barrels 41 of different diameters, so that resin syringes of various specifications can be installed in the installation tube 2, and when the elastic member 232 abuts against the injection barrel 41, the elastic member 232 can closely fit the outer side of the injection barrel 41 under the action of its own elasticity, thereby improving the abutment member 23 abutting against the injection barrel 41 and the limiting effect of the injection barrel 41.

[0043] Specifically, the annular body 231 can be selected as a plastic part, and the elastic part 232 can be selected as a rubber part. The axial direction of the annular body 231 is consistent with the extension direction of the installation channel 21, so that the injection barrel 41 can be inserted into the interior of the annular body 231. The elastic part 232 can be bonded to the inner wall of the annular body 231, so that when the injection barrel 41 is inserted into the annular body 231, the elastic part 232 is deformed and abuts against the outer side surface of the injection barrel 41, and the friction between the elastic part 232 and the injection barrel 41 can stabilize the position of the injection barrel 41 in the installation channel 21 without rotating or moving.

[0044] The inner diameter of the above-mentioned annular body 231 can be selected to be larger than the diameter of the injection barrel 41. After the elastic member 232 is arranged on the inner wall of the annular body 231, the inner diameter of the annular body 231 is reduced to be smaller than or equal to the diameter of the injection barrel 41, so that after the injection barrel 41 is inserted into the inner side of the annular body 231, the elastic member 232 is elastically deformed and tightly abuts against the outer side of the injection barrel 41.

[0045] The elastic member 232 can be selected as a rubber ring, the outer side of the rubber ring is connected to the inner wall of the annular body 231, and the inner side of the rubber ring is used to abut against the outer side surface of the injection barrel 41; of course, the elastic member 232 can also be selected as a plurality of block structures, and the plurality of block structures are arranged on the inner wall of the annular body 231 at intervals along the circumference of the mounting tube 2. After the injection barrel 41 is inserted into the inner side of the annular body 231, the plurality of block structures all abut against the outer side surface of the injection barrel 41.

[0046] Reference Figure 1 and Figure 2 As shown, in some embodiments, there are multiple abutment members 23, and multiple abutment members 23 are arranged on the inner wall of the installation channel 21 at intervals along the extension direction of the installation channel 21, and multiple abutment members 23 abut against the outer side of the injection barrel 41 of the resin injector. In this way, multiple abutment members 23 can limit the injection barrel 41 in the extension direction of the installation channel 21, improve the position stability of the injection barrel 41 in the installation channel 21, and improve the limiting effect of the injection barrel 41 in the installation channel 21.

[0047] Specifically, the number of abutment members 23 can be selected to be four, and of course it can also be selected to be five. Of course, it is not limited to other numbers of abutment members 23. Multiple abutment members 23 are arranged at intervals along the extension direction of the installation channel 21, and the distance between each adjacent two abutment members 23 is equal. Of course, the distance between each adjacent two abutment members 23 can also be selected to be inconsistent.

[0048] Reference Figure 1 and Figure 2 As shown, in some embodiments, a slot 31 is provided on the side of the push member 3 facing away from the driving device 1, and the end of the threaded rod 42 is plugged into the slot 31, so that the push member 3 drives the threaded rod 42 of the resin injector to rotate when the push member 3 rotates along the transmission thread 22. Such a configuration facilitates the connection operation between the threaded rod 42 and the push member 3, so that when the push member 3 rotates, a force is applied to the threaded rod 42 through the side wall of the slot 31, so that the push member 3 rotates and drives the threaded rod 42 to rotate.

[0049] Specifically, a recess may be formed on one side of the pushing member 3 facing away from the driving device 1 to form the card slot 31. Of course, two parallel protrusions may also be provided on the side of the pushing member 3 facing away from the driving device 1, and the portion between the two protrusions forms the card slot 31. The threaded rod 42 has a sheet-like handle at one end away from the injection barrel 41, and the handle is inserted into the card slot 31. When the pushing member 3 rotates, the side wall of the card slot 31 abuts against the handle, so that the threaded rod 42 rotates with the pushing member 3 in the card slot 31.

[0050] Reference Figure 1 and Figure 2As shown, in some embodiments, the driving device 1 includes a controller and a motor, the telescopic end 11 is connected to the motor, and the motor can drive the telescopic end 11 to move along the extension direction of the installation channel 21;

[0051] The controller is electrically connected to the motor so that the controller controls the motor to work. In this way, the controller can control the start and stop of the motor, and the controller can also control the output power of the motor, so that the user can control the push member 3 to move in the installation channel 21 through the controller, and can also control the moving speed of the push member 3 in the installation channel 21, so that the user can control the operation of squeezing the resin from the resin injector through the controller.

[0052] Specifically, the controller can be selected as a chip or a circuit board, and the driving device 1 can be selected to be provided with a shell, the shell is provided with a through hole, the telescopic end 11 is inserted into the through hole, the motor is arranged inside the shell, the motor is connected to the telescopic end 11, and when the motor is started, the telescopic end 11 is driven to move along the extension direction of the installation channel 21; the controller is electrically connected to the motor, so that the controller can control the start and stop of the motor, and the controller can also control the output power of the motor to control the moving speed of the telescopic end 11.

[0053] A button can be optionally set on the above-mentioned driving device 1. The user presses the button to send a signal to the two pairs of controllers. After receiving the signal, the controller controls the motor to start and move the telescopic end 11, so that the telescopic end 11 drives the pushing member 3 to move, so that the pushing member 3 drives the threaded rod 42 to rotate during the movement and squeezes the vertical out of the injection barrel 41.

[0054] Reference Figure 1 and Figure 2 As shown, in some embodiments, a control key 12 is provided on the outside of the driving device 1, and the control key 12 is electrically connected to the controller. When the control key 12 is pressed, a signal is sent to the controller so that the controller controls the motor to start. With such a configuration, when the user holds the driving device 1 with one hand, the user can control the motor to start by pressing the control key 12 with a finger, so that the user can control the telescopic end 11 to move in the installation channel 21 through the control key 12. The control key 12 facilitates the user to control the movement of the telescopic end 11, thereby improving the convenience of the user to use the tubular resin conveyor to extrude the resin from the injection barrel 41.

[0055] Specifically, the control key 12 can be selectively arranged on the outer surface of the driving device 1. After the control key 12 is electrically connected to the controller, pressing the control key 12 can send a signal to the controller. After receiving the signal, the controller controls the motor to start, so that the motor drives the telescopic end 11 to move along the extension direction of the installation channel 21. After releasing the control key 12, the controller stops receiving the signal, so that the controller controls the motor to stop running.

[0056] A power supply can be optionally provided inside the above-mentioned driving device 1, and the power supply is connected to the motor and the controller. A switch 13 is provided on the outside of the driving device 1, and the switch 13 is electrically connected to the controller. The switch 13 is pressed once to send a power-on signal to the controller, and the controller receives the power-on signal and controls the power supply to supply power to the motor, so that the motor starts. The switch 13 is pressed again to send a shutdown signal to the controller, and the controller controls the power supply to stop supplying power to the motor after receiving the shutdown signal.

[0057] Reference Figure 1 and Figure 2 As shown, in some embodiments, the mounting tube 2 is provided with an observation window connected to the mounting channel 21, and the observation window extends along the length direction of the mounting tube 2, so that the user can observe the resin injector in the mounting channel 21 through the observation window. Such a configuration makes it convenient for the user to observe the resin injector in the mounting channel 21, so that the user can immediately observe the amount of resin remaining in the resin injector, thereby determining whether the resin injector in the mounting tube 2 needs to be replaced.

[0058] Specifically, a through hole can be selected to be set on the mounting tube 2 as an observation window. The through hole penetrates the side wall of the mounting tube 2 in the radial direction of the mounting tube 2 so that the through hole is connected to the mounting channel 21. The through hole extends along the length direction of the mounting tube 2 to expand the area of ​​the observation window.

[0059] The above-mentioned observation window is connected to the installation channel 21, so that the user can observe the inside of the installation channel 21 through the observation window. When the resin syringe is installed in the installation channel 21, the user can observe the status of the resin syringe through the observation window, so that the user can instantly observe the amount of resin remaining in the resin syringe, thereby determining whether the resin syringe in the installation tube 2 needs to be replaced.

[0060] Reference Figure 1 and Figure 2 As shown, in some embodiments, at least a portion of the mounting tube 2 is light-permeable, so that the user can observe the resin injector in the mounting channel 21 through the light-permeable portion of the mounting tube 2. In this way, the user can observe the resin injector in the mounting channel 21 through the light-permeable portion of the mounting tube 2, which is convenient for the user to immediately observe the amount of resin remaining in the resin injector, thereby determining whether the resin injector in the mounting tube 2 needs to be replaced.

[0061] Specifically, part of the mounting tube 2 may be made of transparent material. Of course, the entire mounting tube 2 may also be made of transparent material, for example, transparent plastic or glass may be used to make the mounting tube 2, so that light can pass through the light-transmitting portion of the mounting tube 2, that is, the user can observe the resin injector in the mounting channel 21 through the light-transmitting area on the mounting tube 2.

[0062] Reference Figure 1 and Figure 2As shown, in some embodiments, the side of the push member 3 is provided with a matching thread 32, and the matching thread 32 is threadedly connected with the transmission thread 22; or the push member 3 includes a circular piece, and the edge of the circular piece is threadedly connected with the transmission thread 22. In this way, the threaded connection between the matching thread 32 and the transmission thread 22 enables the push member 3 to be stably arranged in the installation channel 21, and when the push member 3 moves in the installation channel 21 along the extension direction of the installation channel 21, the push member 3 can be rotated under the action of the matching thread 32 and the transmission thread 22; the circular piece is relatively small in thickness and weight and is easily pushed by the telescopic end 11, and there is no need to process threads on the side of the push member 3, thereby reducing the manufacturing cost of the push member 3.

[0063] Specifically, the pushing member 3 can be selected to be a columnar structure, the pushing member 3 extends along the extension direction of the installation channel 21, and the outer side surface of the pushing member 3 is provided with a matching thread 32, the matching thread 32 and the transmission thread 22 match each other, and the diameter of the pushing member 3 matches the diameter of the installation channel 21 provided with the transmission thread 22, so that the matching thread 32 of the pushing member 3 can be threadedly connected with the transmission thread 22; the pushing member 3 is arranged in the installation channel 21, and the extension direction of the columnar structure of the pushing member 3 is consistent with the extension direction of the installation channel 21, the telescopic end 11 abuts against one side of the pushing member 3, and the telescopic end 11 moves in the direction away from the driving device 1, so that the telescopic end 11 pushes the pushing member 3 to move.

[0064] The side surface of the pushing member 3 facing the telescopic end 11 can be optionally provided with an abutment protrusion, and the end of the abutment protrusion away from the pushing member 3 is a pointed structure, which abuts against the telescopic end 11 to reduce the friction between the contact positions of the pushing members 3 and facilitate the rotation of the pushing member 3. When removing the pushing member 3 from the installation channel 21, tweezers or other clamps can be used to clamp the abutment protrusion and rotate the pushing member 3, thereby removing the pushing member 3 from the installation channel 21.

[0065] Reference Figure 1 and Figure 2 As shown, in some embodiments, a baffle 24 is provided at one end of the mounting channel 21 away from the driving device 1, and a through hole 241 is provided on the baffle 24, and the injection head of the injection barrel 41 of the resin injector is arranged in the through hole 241. In this arrangement, the baffle 24 serves as an obstruction structure to prevent the resin injector from being separated from the mounting channel 21 from the end of the mounting channel 21 away from the driving device 1 by the pushing force of the pusher 3 when moving; and the injection head is in the through hole 241, so that the extruded resin passes through the through hole 241 and is located outside the mounting tube 2, which is convenient for the user to use the extruded resin to fill the defective part of the patient's teeth.

[0066] Specifically, a baffle 24 can be selected to shield the end of the installation channel 21 away from the driving device 1. The baffle 24 is a circular sheet structure. A through hole is provided at the center of the baffle 24 as a through hole 241. A protrusion is formed at the end of the injection barrel 41 facing away from the threaded rod 42 as an injection head. An extrusion channel connected to the internal space of the injection barrel 41 is provided in the protrusion, and the resin is extruded through the extrusion channel in the injection barrel 41.

[0067] The above-mentioned baffle 24 blocks the end of the mounting channel 21 away from the driving device 1, so the resin syringe cannot be inserted into the mounting channel 21 through the end of the mounting tube 2 away from the driving device 1; when installing the resin syringe, it is necessary to separate the mounting tube 2 from the driving device 1, insert the resin syringe into the mounting channel 21 from the end of the mounting tube 2 connected to the driving device 1, and then install the push member 3 in the mounting channel 21.

[0068] When the tubular resin conveyor provided by the embodiment of the present disclosure is used, the mounting tube 2 and the driving device 1 are in a separated state, and the pushing member 3 is not connected to the mounting tube 2. The resin syringe is inserted into the mounting channel 21 from the end of the mounting tube 2 that is connected to the driving device 1. The injection barrel 41 is first inserted into the mounting channel 21, and then the threaded rod 42 enters the mounting channel 21. After the resin syringe is inserted into the mounting channel 21, the injection barrel 41 is passed through the inner side of the annular body 231, and the elastic member 232 abuts against the outer side surface of the injection barrel 41, and the injection head is set in the through hole 241 of the baffle 24. The pushing member 3 is inserted into the mounting channel 21 from the end of the mounting tube 2 that is connected to the driving device 1, and the end of the threaded rod 42 is inserted into the slot of the pushing member 3. At this time, at least part of the mating thread 32 on the pushing member 3 is threadedly connected with the transmission thread 22, thereby completing the operation of installing the injection barrel 41 in the mounting channel 21.

[0069] The mounting tube 2 with the resin syringe installed inside is detachably connected to the driving device 1, and the telescopic end 11 of the driving device 1 is located in the mounting channel 21. The user holds the mounting tube 2 and the driving device 1 with one hand.

[0070] The user presses the control key 12 with the fingers holding the mounting tube 2 and the driving device 1. After pressing the control key 12, a signal is sent to the controller, so that the controller controls the motor to start. After the motor starts, the telescopic end 11 is driven to move in the direction away from the driving device 1. The telescopic end 11 pushes the pushing member 3 to move in the direction away from the driving device 1. While the pushing member 3 moves in the mounting channel 21, it rotates under the action of the mating thread 32 and the transmission thread 22.

[0071] When the pushing member 3 rotates, the inner wall of the slot 31 applies a force to the handle at the end of the threaded rod 42, so that the pushing member 3 can drive the threaded rod 42 to rotate. Driven by the pushing member 3, the threaded rod 42 moves away from the driving device 1 and rotates in the installation channel 21, thereby squeezing the resin in the injection barrel 41 out of the injection head.

[0072] When the amount of extruded resin is sufficient for use, the user stops pressing the control key 12 , and the controller controls the motor to stop moving, so that the threaded rod 42 stops moving and rotating, thereby stopping the operation of extruding the resin out of the injection cylinder 41 .
