DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0035] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0036] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0038] A plurality of probes are provided in the charging and discharging equipment. In the process of charging and discharging the battery, it is necessary to adjust the arrangement of the plurality of probes according to the model of the battery placed in the battery tray, so that each probe corresponds to one of the plurality of battery cells in the battery. In the related art, the installation method of the probes is usually to open positioning points at several fixed positions on the mounting frame of the charging and discharging equipment, and to position the probes by screws. In this way, when the battery in the battery tray is changed (the arrangement of the plurality of battery cells in the battery will change), it is necessary to remove the plurality of probes from the positioning points and reinstall them to other positioning points to adapt to the arrangement of the battery cells in the new model of the battery.

[0039] Since each probe must be disassembled and then installed by tightening the screws, adjusting the installation position of the probe is time-consuming and laborious. In addition, the location of the set positioning points does not correspond to all types of batteries. Adjusting the probe position by this installation method results in multiple probes being able to charge and discharge only a single or a few types of batteries, which has great limitations in terms of battery compatibility.

[0040] Based on this, the present application example provides a probe and a charging and discharging device, which can quickly and conveniently adjust the installation position of the probe on the charging and discharging device to meet the compatibility and adaptability of multiple probes for charging and discharging various different models of batteries, thereby improving the battery production efficiency.

[0041] The probe and the charging and discharging device are described in detail below through specific embodiments:

[0042] like Figure 1 As shown, an embodiment of the present application provides a probe 01, which can be slidably installed on a mounting frame 21 of a charging and discharging device along a first direction. The probe 01 includes a probe assembly 10 and a clamping assembly 11. The clamping assembly 11 is arranged on the probe assembly 10. The clamping assembly 11 is used to clamp or release the mounting frame 21. The clamping assembly 11 includes a clamping surface for clamping the mounting frame 21, and a first fixing portion 12 is formed on the clamping surface; when the clamping assembly 11 clamps the mounting frame 21, the first fixing portion 12 can cooperate with the second fixing portion 22 of the mounting frame 21 to limit the movement of the probe 01 along the first direction.

[0043] In this embodiment, the probe 01 as a whole can slide on the mounting frame 21 on the charging and discharging device, and the mounting frame 21 can extend along the first direction, so the probe 01 can slide along the extension direction of the mounting frame 21, that is, the first direction. In this way, the probe 01 can be conveniently moved relative to the mounting frame 21 by sliding to change the installation position.

[0044] The probe 01 includes a probe assembly 10 and a clamping assembly 11. The probe assembly 10 can be used to contact the battery cell and charge and discharge. The clamping assembly 11 is arranged on the probe assembly 10. The mounting frame 21 can be plate-shaped. The clamping assembly 11 has a clamping space with a variable spacing, so that the mounting frame 21 can be clamped or released. The probe 01 can slide on the mounting frame 21 through the clamping assembly 11. In the case where the installation position of the probe 01 needs to be adjusted, the clamping assembly 11 first releases the mounting frame 21, and then the probe 01 is slid as a whole. When the probe 01 slides to the target position corresponding to the battery cell to be contacted, the clamping assembly 11 can clamp the mounting frame 21 again, so that the probe 01 is pre-positioned to the mounting frame 21.

[0045] like Figure 1 and Figure 5 As shown, the clamping assembly 11 includes a clamping surface for clamping the mounting frame 21, and a first fixing portion 12 is formed on the clamping surface. The first fixing portion 12 can form a limited fit with a second fixing portion 22 provided on the mounting frame 21, and the second fixing portion 22 on the mounting frame 21 extends along a first direction (i.e., Figure 5 In this way, when the clamping assembly 11 releases the mounting frame 21, the probe 01 can slide to any position along the mounting frame 21, and then the clamping assembly 11 clamps the mounting frame 21, the first fixing portion 12 can form a limited fit with the second fixing portion 22, the clamping assembly 11 will no longer continue to move along the first direction, and the probe 01 can be stably fixed to the mounting frame 21 at the target position.

[0046] Optionally, the first fixing portion 12 includes a plurality of meshing teeth arranged along a first direction, and the tooth tip of each meshing tooth is arranged along a second direction perpendicular to the first direction. The second fixing portion 22 can be a rack extending along the first direction, and the rack includes a plurality of tooth grooves extending along the second direction. In this way, when each meshing tooth is engaged with a tooth groove in the second mounting portion, the first fixing portion 12 and the second fixing portion 22 are limited along the first direction, so that the probe 01 cannot be displaced or moved in the first direction.

[0047] For example, when the model of the battery to be charged and discharged changes, it is necessary to adjust the installation positions of multiple probes 01 so that each probe 01 corresponds to a battery cell in the new battery to be tested. Taking the adjustment of the installation position of a probe 01 as an example, the operator first loosens the clamping assembly 11 clamped on the mounting frame 21, so that the first fixing portion 12 of the clamping assembly 11 and the second fixing portion 22 on the mounting frame 21 are separated, and then slides the probe 01 along the mounting frame 21. When the probe 01 slides to the target position corresponding to the battery cell, the operator can re-clamp the clamping assembly 11 of the probe 01 on the mounting frame 21. When the clamping assembly 11 is re-clamped on the mounting frame 21, the first fixing portion 12 on the clamping assembly 11 and the second fixing portion 22 on the mounting frame 21 form a mutual limit again, and the probe 01 can no longer be displaced. The probe 01 is stably fixed at a position corresponding to the battery cell in the new battery. After the installation positions of multiple probes 01 are readjusted, the battery with the changed model can be charged and discharged.

[0048] In this way, the probe 01 provided in the embodiment of the present application can slide along the mounting frame 21 of the charging and discharging equipment through the clamping assembly 11. When the probe 01 slides to the target position corresponding to the battery cell, the clamping assembly 11 can be clamped on the mounting frame 21, and the first fixing portion 12 on the clamping surface of the clamping assembly 11 is limitedly matched with the second fixing portion 22 on the mounting frame 21, so as to fix the probe 01 at the target position, thereby realizing stepless adjustment of the position of the probe 01, so as to activate or test batteries of different specifications in the battery tray, and meet the compatibility requirements of the charging and discharging equipment using the probe 01 for charging and discharging batteries of different specifications. At the same time, the clamping assembly 11 realizes positioning with the mounting frame 21 by clamping, eliminating cumbersome disassembly operations, thereby improving the production efficiency of the battery.

[0049] In order to further improve the efficiency of the clamping assembly 11 in clamping and releasing the mounting frame 21, in other embodiments, such as Figure 1 , Figure 2 and Figure 4As shown, the probe assembly 10 includes a main shaft 101 and a probe head 106 connected to a first end of the main shaft 101. The main shaft 101 is inserted into the clamping assembly 11 and can form an abutment with at least a portion of the clamping assembly 11. The probe 01 also includes a first elastic member 16, which is sleeved on the main shaft 101. When the clamping assembly 11 releases the mounting frame 21 under the action of tension, the first elastic member 16 is deformed. When the tension is released, the clamping assembly 11 automatically returns to the state of clamping the mounting frame 21 under the action of the elastic force generated by the deformation of the first elastic member 16, thereby improving the efficiency of adjusting the installation position of the probe 01.

[0050] In a possible embodiment, the first elastic member 16 is sleeved on the main shaft 101, one end of the first elastic member 16 can abut on the second end of the main shaft 101, and the other end can abut on the clamping assembly 11. Along the axial direction of the main shaft 101, the clamping assembly 11 is located between the first elastic member 16 and the probe head 106. Optionally, the first elastic member 16 can be a spring.

[0051] When the clamping assembly 11 is clamped on the mounting frame 21, when the probe head 106 is subjected to a pulling force in a direction away from the clamping assembly 11, the probe head 106 drives the spindle 101 to move synchronously. In addition, the clamping assembly 11 can be opened with the movement of the spindle 101 to release the mounting frame 21. At the same time, since one end of the first elastic member 16 can abut against the stopper 107 on the spindle 101, the first elastic member 16 is compressed when the spindle 101 moves. When the pulling force on the probe head 106 is released, the reset force of the first elastic member 16 resets the spindle 101 and the clamping assembly 11, and the clamping assembly 11 re-clamps the mounting frame 21.

[0052] In another possible embodiment, the first elastic member may be located in a clamping assembly (not shown in the figure), the clamping assembly may include a first clamping member and a second clamping member, the first clamping member and the second clamping member may be controllably moved closer or farther away, so that the clamping assembly clamps or releases the mounting frame, and the two ends of the first elastic member are respectively connected to the first clamping member and the second clamping member. Optionally, the first elastic member may be a tension spring.

[0053] When the clamping assembly is clamped on the mounting frame, when the probe head is subjected to a pulling force in a direction away from the clamping assembly 11, the probe head drives the main shaft to move synchronously. The first clamping member and the second clamping member can be opened with the movement of the main shaft to release the mounting frame. At the same time, the first elastic member is deformed due to the first clamping member and the second clamping member moving away from each other. When the pulling force on the probe head is released, the restoring force of the first elastic member makes the first clamping member and the second clamping member move closer to each other, and the clamping assembly re-clamps the mounting frame.

[0054] Thus, by providing the first elastic member 16 in the probe 01, when the installation position of the probe 01 needs to be adjusted, the clamping assembly 11 can be loosened from the mounting frame 21 by pulling the probe head 106, and the probe 01 can adjust its installation position along the mounting frame 21. After the probe head 106 is loosened, the elastic force of the first elastic member 16 can restore the clamping assembly 11 to the state of clamping the mounting frame 21, thereby improving the efficiency of adjusting the installation position of the probe 01.

[0055] In some embodiments, Figure 1 , Figure 2 ,and Figure 4 As shown, the clamping assembly 11 includes a gland 13 and a fixing seat 14, which are respectively located on both sides of the mounting frame 21, and a clamping space for clamping the mounting frame 21 is formed between the gland 13 and the fixing seat 14, and the first end of the first elastic member 16 abuts against the gland 13, and the second end of the first elastic member 16 abuts against the stopper 107 located at the second end of the main shaft 101, and the fixing seat 14 can be controllably moved away from the gland 13, while the first elastic member 16 is deformed. When the force pulling the fixing seat 14 is released, the fixing seat 14 approaches the gland 13 under the action of the reset force of the first elastic member 16, thereby achieving the release and clamping of the mounting frame 21.

[0056] Specifically, the gland 13 can be in contact with the top of the mounting frame 21, and the spindle 101 passes through the gland 13 and is movably connected to the gland 13. In this way, when the probe head 106 is subjected to a pulling force in a direction away from the clamping assembly 11, that is, when the probe head 106 is pulled downward, the probe head 106 drives the spindle 101 to move downward, and the gland 13 is limited to the mounting frame 21. Therefore, the first elastic member 16 located between the stopper 107 at the second end of the spindle 101 and the gland 13 is compressed and deformed.

[0057] The fixing seat 14 is located below the mounting frame 21, and the spindle 101 is also disposed through the fixing seat 14, and forms an abutting relationship with the fixing seat 14 along the radial direction of the spindle 101, that is, at least part of the spindle 101 extends in the radial direction and the end portion abuts against the inner wall of the fixing seat 14. When the probe head 106 is pulled down, the abutting relationship between the spindle 101 and the fixing seat 14 generates friction, and the friction makes the fixing seat 14 move downward synchronously with the spindle 101, so that the fixing seat 14 moves away from the gland 13, and the distance between the fixing seat 14 and the gland 13 increases so that the two can release the mounting frame 21. When the pulling force pulling the probe head 106 is released, the elastic force of the first elastic member 16 makes the spindle 101 move upward, and at the same time, the spindle 101 drives the fixing seat 14 to approach the gland 13, and the gland 13 and the fixing seat 14 clamp the mounting frame 21 again.

[0058] For example, when the installation position of the probe 01 needs to be adjusted, the operator can pull down the probe head 106, and the probe head 106 drives the main shaft 101 to move downward. The main shaft 101 drives the fixing seat 14 to move downward through friction, and the distance between the fixing seat 14 and the pressure cover 13 increases, so that the mounting frame 21 can be released. At the same time, the first fixing portion 12 and the second fixing portion 22 are also separated because the pressure cover 13 and the fixing seat 14 release the mounting frame 21, and the installation position of the probe 01 can be adjusted. When the operator moves the probe 01 to the target position by pulling the probe head 106, the probe head 106 can be released. The elastic force generated by the first elastic member 16 can pull the main shaft 101 to move upward, and the main shaft 101 drives the fixing seat 14 to approach the pressure cover 13 to re-clamp the mounting frame 21. The first fixing portion 12 and the second fixing portion 22 also re-generate a limit fit to stably fix the probe 01 at the target position.

[0059] In this way, when the installation position of probe 01 needs to be adjusted, one only needs to simply pull the probe head 106 and slide the probe 01 to the target position, and then release the probe head 106 to complete the replacement of the installation position of probe 01 to meet the charging and discharging of batteries of different models, thereby greatly improving the battery production efficiency.

[0060] In a possible embodiment, the first fixing portion may be arranged on a surface of the gland for clamping the mounting frame (not shown in the figure). The second fixing portion may be arranged on a surface of the mounting frame for abutting against the gland, that is, the upper surface of the mounting frame.

[0061] It can be understood that since the pressure cover is movably connected to the main shaft, after the fixing seat is separated from the mounting frame, the pressure cover can be pulled upward again to separate the first fixing part on the pressure cover from the second fixing part on the mounting frame. When the probe moves to the target position, the probe head and the pressure cover are released at the same time, so that the pressure cover and the fixing seat can re-clamp the mounting frame, and the first fixing part and the second fixing part can also re-form a limiting fit, and the probe is stably fixed at the target position.

[0062] In another possible embodiment, the first fixing portion 12 can be disposed on a surface of the fixing seat 14 for clamping the mounting frame 21 , and the second fixing portion 22 can be disposed on a surface of the mounting frame 21 for abutting against the fixing seat 14 , that is, the lower surface of the mounting frame 21 .

[0063] It can be understood that since the fixing base 14 can be pulled by the probe head 106 and separated from the mounting frame 21, the first fixing portion 12 is set on the fixing base 14 for clamping the surface of the mounting frame 21, so that the operation of the fixing base 14 releasing the mounting frame 21 and the operation of separating the first fixing portion 12 from the second fixing portion 22 can be completed simultaneously by pulling down the probe head 106, thereby further improving the efficiency of adjusting the installation position of the probe 01.

[0064] like Figure 3 and Figure 4 As shown, the main shaft 101 includes a shaft body 102 connected to the probe head 106 and a shaft sleeve 103 sleeved outside the shaft body 102 . A positioning portion 104 is provided at the end of the shaft sleeve 103 , and the positioning portion 104 is used to abut and cooperate with the fixing seat 14 .

[0065] Specifically, if Figure 4 As shown, the main shaft 101 includes a shaft body 102 connected to a probe head 106 and a shaft sleeve 103 sleeved on a portion of the shaft body 102. Figure 4 As shown, a positioning portion 104 is formed at one end of the sleeve 103 facing the probe head 106 . The positioning portion 104 can extend radially along the shaft body 102 and away from the shaft body 102 . The positioning portion 104 is used to form a radial abutment relationship with the fixing seat 14 along the shaft body 102 .

[0066] Optionally, the shaft sleeve 103 may include a plurality of positioning portions 104, and the plurality of positioning portions 104 are arranged at intervals along the circumference of the shaft body 102. Specifically, in order to improve the stability of the positioning portions 104 limiting the fixing seat 14, the number of the positioning portions 104 may be three.

[0067] Optionally, the cross section of the part where the shaft body 102 and the bushing match can be non-circular, that is, the shaft body 102 can be cut off in the axial direction, so that the part of the shaft body 102 is a non-rotating body. The space in the sleeve 103 can be adapted to the shaft body 102, so that the shaft body 102 and the sleeve 103 can be mutually limited in the circumferential direction, and when one of the sleeve 103 or the shaft body 102 rotates, the other can rotate synchronously. At the same time, the caliber of the first end of the sleeve 103 provided with the positioning portion 104 can be relatively smaller than that of the second end, and the sleeve 103 is also formed with a deformation groove, which can be axially connected to the second end of the sleeve 103, so that an interference fit can be formed between the sleeve 103 and the main shaft 101, and the sleeve 103 and the main shaft 101 are mutually limited in the axial direction. When one of the sleeve 103 or the shaft body 102 moves in the axial direction, the other can move synchronously.

[0068] like Figure 4 As shown, the fixing seat 14 includes an installation channel 141, and one end of the sleeve 103 is provided with a positioning portion 104 extending into the installation channel 141. The positioning portion 104 abuts against the inner wall of the installation channel 141 along the radial direction of the main shaft 101. When the probe head 106 is pulled, the sleeve 103 drives the fixing seat 14 to move downward and separate from the pressure cover 13 through the abutment relationship between the positioning portion 104 and the wall of the installation channel.

[0069] In other embodiments, the probe 01 further includes a second elastic member 17 sleeved on the shaft body 102 , one end of the second elastic member 17 abuts against the probe head 106 , and the other end of the second elastic member 17 abuts against one end of the sleeve 103 extending into the fixing seat 14 .

[0070] During the process of the probe 01 charging and discharging the battery cell, the battery cell may need to move toward the probe 01 so as to abut against the probe 01. When the probe head 106 contacts the battery cell, it will bring a certain impact to the probe head 106. Since the two ends of the second elastic member 17 sleeved on the shaft body 102 abut against the shaft sleeve 103 and the probe head 106 respectively, the elastic force of the second elastic member 17 can be less than the elastic force of the first elastic member 16. Therefore, when the probe head 106 is impacted, the second elastic member 17 is compressed. The elastic force generated by the compression of the second elastic member 17 can buffer the impact between the probe head 106 and the battery cell to protect the probe head 106 and increase the service life of the probe head 106.

[0071] The second aspect of the present application also provides a charging and discharging device, such as Figure 5 As shown, the charging and discharging device includes the probe 01 component and the rack 20 provided in the first aspect of the embodiment of the present application. The rack 20 includes a first direction ( Figure 5 The mounting frame 21 extends in the X direction (in the X direction), and a slide groove 213 extending in the first direction is provided in the mounting frame 21. Figure 5 As shown, a second fixing portion 22 extending along the first direction is provided on the mounting frame 21 , and the second fixing portion 22 cooperates with the first fixing portion 12 of the probe 01 to limit the movement of the probe 01 along the first direction.

[0072] Optionally, the second fixing portion 22 can be a rack extending in the first direction, and the rack includes a plurality of tooth grooves extending in the second direction. The first fixing portion 12 includes a plurality of meshing teeth arranged in the first direction, and the tooth tip of each meshing tooth is arranged in a second direction perpendicular to the first direction. In this way, when each meshing tooth is engaged with a tooth groove in the second mounting portion, the first fixing portion 12 and the second fixing portion 22 are limited in the first direction, so the probe 01 cannot be displaced or moved in the first direction.

[0073] like Figure 5 and Figure 6 As shown, the probe head 106 assembly of the probe 01 can be inserted into the slide groove 213 in the mounting frame 21, and both ends of the clamping assembly 11 of the probe 01 can be snapped into the mounting groove. When the first fixing portion 12 and the second fixing portion 22 are separated, the probe 01 can move in the slide groove 213 through the clamping assembly 11.

[0074] In this way, the charging and discharging device includes a probe 01 that can slide along the mounting frame 21. The clamping component 11 in the probe 01 can not only be clamped on the mounting frame 21, but the probe 01 can also slide in the slide groove 213 through the clamping component 11, that is, the clamping component 11 can not only realize the clamping function, but also has a sliding guiding function when the installation position of the probe 01 is adjusted. The above two functions are realized by the clamping component 11, which simplifies the structure of the probe 01 and makes the structure of the probe 01 more compact.

[0075] In order to enable the probe 01 to slide in the mounting frame 21 through the clamping assembly, in some embodiments, as Figure 7 As shown, the pressure cover 13 of the probe 01 is arranged across the slide groove 213, and the two ends of the pressure cover 13 are respectively abutted against the mounting frame 21. Figure 3 As shown, the fixing seat 14 of the probe 01 includes a limiting portion 144 and a guide portion 146 disposed on a seat body 145 . The guide portion 146 extends into the slide groove 213 , and the seat body 145 abuts against the bottom of the mounting frame 21 .

[0076] like Figure 6 As shown, the mounting frame 21 includes two mounting plates 211 extending along a first direction. A connecting block 212 is sandwiched between the two mounting plates 211. The connecting block 212 is located at the end of the mounting plates 211, and a sliding groove 213 is formed between the two mounting plates 211. The second fixing portion 22 is disposed below one of the mounting plates 211.

[0077] The pressure cover 13 may be constructed as a strip-shaped structure. The pressure cover 13 is arranged across the slide groove 213 along the length direction, and two ends of the pressure cover 13 are respectively abutted against the two mounting plates 211 .

[0078] like Figure 7 As shown, the fixing seat 14 may include a stopper 144 and a seat body 145, the spindle 101 may pass through the seat body 145, and the mounting channel 141 of the fixing seat 14 is formed in the seat body 145 for the spindle 101 to pass through. The seat body 145 is centrally located on the stopper 144, and the portion of the stopper 144 extending out of the seat body 145 abuts against the two mounting plates 211 respectively. The first fixing portion 12 corresponds to the second fixing portion 22 and is disposed on the portion of the stopper 144 that can abut against the mounting plate 211.

[0079] Optionally, two guide portions 146 are further provided on the limiting portion 144. The two guide portions 146 can be respectively located on both sides of the seat body 145. The distance between the two guide portions 146 can be slightly smaller than the width of the slide groove 213. In this way, there will be no interference with the slide groove 213, and the fixed seat 14 can slide stably in the slide groove 213 through the guide portions 146.

[0080] In this way, when the first fixing portion 12 and the second fixing portion 22 are separated, the probe 01 can slide along the slide groove 213 through the pressure cover 13 and the fixing seat 14, so that the probe 01 can be quickly and conveniently moved to the target position.

[0081] When the model of the battery to be charged and discharged changes, if the arrangement of the new battery cells cannot be adapted by retracting the probe head 106, that is, there are too many probes 01 on the mounting frame 21, it may be necessary to remove some of the probes 01 from the mounting frame 21. In some embodiments, the pressure cover 13 can rotate relative to the main shaft 101 in the probe 01. When the pressure cover 13 is rotated to the disassembly position relative to the main shaft 101, the pressure cover 13 can pass through the slide groove 213, and the probe 01 can be moved out of the slide groove 213, so that the probe 01 and the mounting frame 21 are detachable.

[0082] As described above, the gland 13 is constructed in a strip shape, the length of the gland 13 is longer than the width of the slide slot 213, and the width of the gland 13 is smaller than the width of the slide slot 213. Since the gland 13 is movably connected to the main shaft 101, the gland 13 can rotate relative to the main shaft 101. When the gland 13 rotates to a disassembly position parallel to the slide slot 213 and above the slide slot 213, the abutment relationship between the gland 13 and the mounting frame 21 is released and the gland 13 can pass through the slide slot 213, and the entire probe 01 can be disassembled from the mounting seat.

[0083] It should be noted that before removing the probe 01 from the mounting frame 21 , the braided wire 26 needs to be removed from under the probe 01 first.

[0084] In order to prevent the gland 13 from rotating due to erroneous operation, in some embodiments, as Figure 7 As shown, a sinking groove 214 communicating with the slide groove 213 is provided on the mounting frame 21 , and at least a portion of the gland 13 extends into the sinking groove 214 to limit the gland 13 from rotating relative to the main shaft 101 .

[0085] Since the shape of the pressure cover 13 is configured as a strip, the sinking groove 214 may also be configured as a strip to match the pressure cover 13 and limit the pressure cover 13 .

[0086] When the probe 01 needs to be removed from the mounting frame 21 , the pressure cover 13 can be pulled upward to disengage the pressure cover 13 from the sinking groove 214 , and then the pressure cover 13 is rotated to the removal position, so that the probe 01 can be removed from the mounting frame 21 .

[0087] Thus, by providing the sinking groove 214 on the mounting frame 21 , it is possible to avoid the probe 01 being separated from the mounting frame 21 in the working state due to the rotation of the pressure cover 13 due to erroneous operation.

[0088] In some embodiments, Figure 8 and Fig. 9 As shown, the frame 20 further includes a fixing plate 23, a guard plate 24 and a support column 25. The fixing plate 23 is located above the mounting frame 21 and also extends along the first direction.

[0089] like Fig. 9 As shown, the guard plate 24 is located on the side of the fixing plate 23, one end of the guard plate 24 is connected to the fixing plate 23, and the other end of the guard plate 24 is connected to the mounting frame 21. The guard plate 24 is provided with a plurality of openings 241 at intervals, and the braided wire 26 is connected to the probe 01 through the openings 241.

[0090] like Figure 8 As shown, both ends of the support column 25 are connected to the fixing plate 23 and the mounting frame 21 respectively, and at least part of the support column 25 corresponds to the opening 241 to improve the structural strength of the guard plate 24 at the part where the opening 241 is formed.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
