Description

Technical Field

[0001] The invention relates to the field of labor tool locks, in particular to an intelligent anti-lost tool lock which is convenient to manage. Background Art

[0002] The labor tool lock is a lock installed on the production workstation. The user can lock the commonly used and necessary tools in the production process to prevent others from taking them or losing them. At the end of work, the supervisor will go to each workstation to take inventory of the tools and record the return of the tools.

[0003] Traditionally, tool cabinets are used to store labor tools. Operators use the tools and put them back into the tool cabinet before leaving get off work, and the return of the tools is supervised and counted.

[0004] At present, there are some tool locks for single tools, that is, tool locks are used to lock a tool, such as scissors, hammers, etc. Most of the existing labor tool locks are only used on-site, and tool inventory also needs to be observed and recorded at each workstation, which is time-consuming and labor-intensive. In addition, tool locks are customized products, and the tools that can be stored cannot be changed. For multiple types of tools, it is impossible to achieve a universal standardized design. Management is also not very convenient, and it cannot have an authorization function (for example, all tools are locked and not allowed to be used during off-duty hours, and can only be authorized by managers in special circumstances). However, the existing technology has not yet achieved the relevant effect, and the operator of this workstation can access the tools at the workstation at any time. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent anti-lost tool lock that is easy to manage, so as to solve the problems in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The utility model discloses an intelligent anti-lost tool lock which is convenient to manage, comprising a lock box, a lock cover, a matching block and a bottom plate; the lock box is a box body which is open from top to bottom, the lock cover is hingedly connected to the top surface of the lock box, the bottom of the lock box is fixedly connected to the bottom plate, there are a total of several matching blocks, and the matching blocks are movably arranged in the lock box. During non-working periods, the tool lock is used to lock some tools in one place, which is convenient for counting the tool return status and preventing the loss of tools. The lock box is the appearance of the smart anti-lost tool lock. The lock cover and the lock box are hinged on one edge, which is convenient for users to open and close the lock box to take tools. The lock box is open at the top and bottom and is closed by the lock cover and the bottom plate to install the internal structure. The matching block is movably arranged in the lock box. During the initial setting, according to the different shapes of the tools to be stored, such as scissors, hammers and other tools of different shapes, the matching block can be set to different inner cavity shapes. As long as the size of the storage part does not exceed the size that the smart anti-lost tool lock can accommodate, the tool lock can make corresponding internal storage cavity deformation. When the smart anti-lost tool lock is used later, only the tool shape at the initial setting can be placed. It can detect whether the object placed in the smart anti-lost tool lock is the required object to prevent impersonation.

[0008] Furthermore, the intelligent anti-lost tool lock also includes a locking plate and a signal plate assembly. A locking plate groove is provided on the side of the lock box, and the locking plate groove is parallel to the upper and lower surfaces of the lock box. The locking plate is inserted into the locking plate groove and enters the lock box to hook the matching block. The signal plate assembly is arranged in the lock box, and the signal plate assembly is located below the matching block. When the locking plate is used for initial setting, the deformation of several matching blocks inside the lock box is locked. After the locking plate is pulled out from the side of the lock box, the matching block can rise and fall in the lock box. When it is used specifically, the locking plate is pulled out, and the tools that need to be stored in the device later are placed on top of the matching block. The tool is pressed down and the lock cover is covered. The matching block is deformed to a corresponding shape inside the lock box. Then the locking plate is reinserted into the side of the lock box and extends into the lock box. After the locking plate hooks the matching block, even if the tool is taken out of the lock box, the matching block is positioned at its position and will not bounce back to the initial state (that is, the upper surfaces of all matching blocks are at the same height). The locking plate locks the matching block position as a stereotyped recording function. After the tool is used, it is put into the lock box. When the shape setting is put in, the pit is pressed out on the matching block. The more matching blocks there are and the smaller the single matching block is, the more accurate the outer contour of the tool that can be fitted by the matching block is. In actual use or manufacturing, the matching block group with the corresponding fitting accuracy is produced according to the accuracy required by the use occasion. After the matching block is squeezed into a certain contour shape, it only provides a storage cavity for the tool, and cannot identify whether the tool has been placed. The signal board component under the matching block is used to determine whether the tool has been placed in the lock box. For example, a pressure sensor can be used on the matching block to identify whether there is an object above and transmit the signal to the signal board component, or it can be detected by a tiny button whether the tool has returned to its position. The signal board component then transmits the information of whether the tool is in place to the device, which is received by the control center to count the return of the tool. This tool lock is used on multiple workstations in a production site, and all are connected to a control center using signal lines. When leaving get off work, the control center can directly obtain the return status of the tool without having to count them one by one.

[0009] Furthermore, a lock pin assembly is provided on the upper side of the lock box, a lock cover slot is provided between the lock pin assembly and the box-shaped body of the lock box, a lock cover lock plate is provided on the side of the lock cover, the lock cover lock plate is inserted into the lock cover slot, a second lock hole and a third lock hole are provided on the lock cover lock plate, and the axes of the second lock hole and the third lock hole are perpendicular to the plate plane of the lock cover lock plate; the lock pin assembly comprises a fingerprint lock, a first lock pin, a second lock pin and a third lock pin, the first lock pin, the second lock pin and the third lock pin are extended and retracted from the lock pin assembly by a driving component inside the lock pin assembly, the lock pin assembly is located above the lock plate, the first lock pin locks or opens the lock plate downward, the second lock pin and the third lock pin are both facing the lock cover slot, the fingerprint lock is electrically connected to the second lock pin, the second lock pin is inserted into the second lock hole, and the third lock pin is inserted into the third lock hole; an electrical interface is also provided on the side of the lock box, and the lock pin assembly is electrically connected to the electrical interface. The lock pin assembly is the specific opening and locking actuator of the tool lock, wherein the first lock pin is used to lock or open the lock plate. When the tool lock is initially set or the type of tool to be stored needs to be replaced, the first lock pin is opened, the lock plate is pulled out, and the matching block customization process described above is executed. After the initial setting is completed, the first lock pin is inserted downward into the lock plate so that the lock plate cannot be pulled out. The second lock pin is an on-site lock, and the third lock pin is a remote lock. The lock pin assembly is connected to an external control center through an electrical interface on the lock box. The electrical wiring and electrical settings are in accordance with the principle process and operation process described in the content of this manual. The lock pin assembly communicates and supplies power to the outside world remotely. The first lock pin and the third lock pin are opened and closed according to external instructions. Specifically, when the power is completely off and the signal is lost, the first lock pin, the second lock pin and the third lock pin are in a retracted state in the lock pin assembly. This can be conveniently achieved by means of electromagnets, electromagnetic coils, etc. There are also many standard accessories with similar functions on the market. After the initial setting of the tool lock (that is, the matching block has completed fitting the tool contour and using the lock plate to lock the position) is completed and connected to the external electrical After the connection, the first lock pin extends out and inserts into the lock plate. When the tool lock is always connected to the control center, the initial setting cannot be changed. The third lock pin is a timed lock pin. The working hours in the production field are basically fixed. During working hours, the third lock pin is opened according to the remote command. At this time, you only need to open the second lock pin to take the tool on site. When leaving get off work, the control center remotely obtains the tool lock signal on each workstation. The third lock pin of the tool lock on the workstation where the tool has been returned extends to lock the lock cover. The lock cover is kept closed during non-working hours. The tool lock on the workstation where the tool has not been returned gives the control center a "not returned" signal, and the control center records the workstation information and feeds it back to the relevant supervisory personnel; the way for the on-site operator to open the second lock pin during working hours is achieved through the fingerprint lock. The fingerprint lock records information locally, is safe and confidential, and can achieve the purpose of special use by one person. The fingerprint lock can also record the fingerprint information of multiple people, who are all authorized users of the tool. The on-site operator uses the fingerprint lock to open the second lock pin to take the tool in the lock box by himself, and puts the tool back in place and closes the lock cover a few minutes before leaving get off work.If tools need to be used at a workstation outside working hours, the control center needs to remotely open the third lock pin on the workstation, which is the "authorized use" outside working hours.

[0010] Furthermore, the lock box is a rectangular box body, and the matching blocks are arranged in the lock box in a rectangular array. The matching blocks include block columns and a first spring. A partition parallel to the upper and lower surfaces is provided in the lock box, and a plurality of through holes are provided on the partition. The lower section of the block column passes through the partition, and the major diameter of the block column head is larger than the major diameter of the lower section. A first spring is provided between the block column head and the partition, and the first spring is sleeved on the lower section of the block column. The lower section of the block column is provided with a plurality of equidistant positioning ring grooves, and the locking plate is provided with a plurality of plate cores and lock ears. The plate core is inserted between the positioning ring grooves of equal height on two adjacent block columns, and the lock ear is located below the lock pin assembly. A through hole is provided on the lock ear, and the lock ear through hole is located directly below the first lock pin; the matching block also includes a signal column and a second spring. The signal column is divided into an upper section and a lower section, and the diameter of the upper section is larger than that of the lower section. A vertical spring is provided in the block column. A stepped through hole, a signal column is arranged in the block column, a second spring is arranged between the bottom end surface of the upper section and the stepped surface in the block column, the total length of the signal column is greater than the total length of the block column, and when the second spring is in a relaxed state, the bottom of the signal column is located in the block column; the signal board assembly includes a board body, a signal circuit, a contact switch and a reset spring, the board plane of the board body is parallel to the upper and lower surfaces of the lock box, the board body is provided with the same number of contact switches as the matching blocks, the contact switches are respectively located directly below each matching block, the contact switches are arranged in a groove on the surface of the board body, the top of the contact switch is lower than the upper surface of the board body, and the major diameter of the groove where the contact switch is located is smaller than the bottom diameter of the block column; the contact switches are respectively electrically connected to the signal circuit inside the board body, the signal circuit is electrically connected to the electrical interface, and the reset spring is arranged between the board body and the bottom plate. The matching block specifically achieves the contour fitting effect through the first spring and the locking plate. When the matching block is initialized, the first springs of all matching blocks set the block columns to which they are connected at the same height, the locking plate is pulled out of the lock box, and the tool to be stored is placed in the lock box to squeeze the matching block. Some of the first springs are compressed, the block column descends, and the lower section of the block column is provided with a number of equidistant positioning ring grooves which are insertion grooves for the locking plate. The thickness of the tool put into the lock may change continuously, but we can slightly ignore a certain thickness difference and use the distance of the positioning ring grooves as the minimum unit of height change of the matching block. The smaller the spacing of the positioning ring grooves, the finer the thickness fitting of the matching block to the tool. The tool lock uses the total setting height range of the positioning ring grooves on the block column as the thickness range of the tool that can be placed. Within this thickness range, different matching blocks always have positioning ring grooves of equal height that can be used to insert the locking plate for locking. The bottom of the block column presses down the signal board assembly, but because the bottom of the block column does not contact the contact switch on the upper signal board assembly, the block column does not give a signal whether the tool is in place. The contact switch is squeezed through the signal column. The total length of the signal column is slightly larger than the total length of the block column, and when the second spring is relaxed, the bottom of the signal column is located inside the block column. That is to say, when the tool is not in place, the bottom end of the signal column does not press the corresponding contact switch underneath it. After the tool is placed in the lock box, the tool presses down the signal column, and the bottom end of the signal column also presses down the contact switch below. The signal circuit gives a dot matrix signal corresponding to this tool and transmits it to the control center through the electrical interface on the lock box. The signal board assembly is similar to a "mechanical keyboard" with no key conflict.Because the tool lock uses matching blocks to fit and store different types of tools, and these tools have different thicknesses, when changing the type of tool, the signal plate assembly should always be against the bottom end of the lowest block column, and the reset spring plays this role. A side panel groove can also be opened on the top of the side of the lock box. The side panel groove is away from the hinged side of the lock cover of the lock box and the side where the lock pin assembly is located. The lifting edge of the lock cover is preferred. The setting of the side panel groove can facilitate the placement of long-handled tools. When placing, you only need to put the tool head into the lock box and lock it. The handle can be exposed, which is conducive to reducing the volume of the tool lock.

[0011] As an optimization, a signal board terminal is provided on the side of the plate body, and an electrode groove is provided on the inner side wall of the lock box. The signal board terminal is embedded in the electrode groove and can slide up and down along the electrode groove; the signal circuit is electrically connected to the signal board terminal, and the electrode groove is electrically connected to the electrical interface. The signal board assembly and the electrical interface need to be electrically connected. Since the height of the signal board assembly may vary slightly depending on the tools stored in the tool lock, it is not suitable to directly use thin cables for electrical connection, because the height change may cause the thin cables to break or become entangled; the signal board terminal is provided on the side of the plate body, and the electrode groove is provided on the inner side wall of the lock box, so that the electrical connection is in contact in the form of a sliding groove, which not only maintains sufficient sliding contact, but also eliminates the risk of cable entanglement or breakage.

[0012] As an optimization, the extension and retraction driving components of the first lock pin, the second lock pin and the third lock pin in the lock pin assembly are electromagnetic contactors. Electromagnetic contactors are commonly used switch components in electromagnetic relays, and this structure is also widely used in solenoid valves. Its basic principle is that after the contactor is energized, magnetic force is generated, the armature is attracted, and the armature is connected to the parts to be moved. The on and off power of the contactor can realize the short-range extension and retraction of the first lock pin, the second lock pin and the third lock pin. Using electromagnetic contactors as extension and retraction driving components is fast, accurate and reliable, and has a small structure size.

[0013] As an optimization, the first spring and the second spring are corrugated springs. The corrugated spring, also known as the wave spring or wave spring, is a thin-sheet annular elastic metal element composed of a number of wave crests and troughs. A number of corrugated sheets are stacked together in an axially staggered manner to form a cylindrical spring. It has a similar installation position to the cylindrical spring, but compared to the cylindrical spring, the elastic load of the corrugated spring is released more evenly. Under the same elastic coefficient requirement, the structural size of the corrugated spring is smaller.

[0014] As an optimization, the groove side of the positioning ring groove forms an acute angle with the horizontal plane. When the matching block is pressed down, the positioning ring grooves on different block columns cannot automatically reach the same height position. If the side of the positioning ring groove is perpendicular to the axis of the block column, then the locking piece needs to be made thinner and the force of the tool pressing down the matching block needs to be manually slightly adjusted when inserting the locking piece so that the locking piece can be fully inserted. The groove side of the positioning ring groove forms an acute angle with the horizontal plane, which has a guiding effect. The thickness of the locking piece is equal to the vertical length of the bottom of the positioning ring groove. After the locking piece passes through a positioning ring groove and comes to the next positioning ring groove, the locking piece contacts the side of the groove. Since the side of the groove is inclined, when the locking piece is inserted into this positioning ring groove, this positioning ring groove will continuously rise or fall so that the locking piece is aligned with this groove.

[0015] As an optimization, the acute angle between the groove side of the locating ring groove and the horizontal plane is 5~20°. The larger the inclination angle, the longer the axial length occupied by the groove side of the locating ring groove, and the smaller the inclination angle, the smaller the guiding effect of the groove side of the locating ring groove, but it is conducive to setting more locating ring grooves on a block column. Comprehensively considering the thickness fitting accuracy of the tool, the acute angle between the groove side and the horizontal plane is 5~20°.

[0016] As an optimization, a fixing plate is provided on the side of the bottom plate, and bolt holes are provided on the fixing plate. The fixing plate can facilitate the fixing of the tool lock at the work station.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention uses matching blocks to fit the tool contour, so that the tool lock can be used to store tools of different shapes, the degree of standardization is improved, and tools of similar size in the production site only need to be equipped with a batch of tool locks of the same model to complete tool management and inventory; the storage cavity formed by the matching blocks after fitting can only hold objects of the same shape to prevent foreign objects from impersonating; after the tool is placed in the lock box, the signal column presses down the contact switch to give a dot matrix signal from the electrical interface, which is convenient for remote and accurate knowledge of the tool's position status; the double-track lock pin when the tool is taken out, one on-site and one remote, is convenient for management and locking the lock box during non-working hours.

There are several matching blocks 3, and the matching blocks 3 are movably arranged in the lock box 1. During non-working period, the tool lock is used to lock some tools in one position, which is convenient for counting the return of tools and preventing the loss of tools. The lock box 1 is the appearance of the smart anti-lost tool lock, and the lock cover 2 is hinged on one edge with the lock box 1, which is convenient for users to open and close the lock box 2 to take tools. The lock box 1 is open at the top and bottom and closed by the lock cover 2 and the bottom plate 6 in order to install the internal structure. The matching block 3 is movably arranged in the lock box 1. During the initial setting, according to the different shapes of the tools to be stored, such as scissors, hammers and other tools of different shapes, Fig.11 As shown, the matching block 3 can be set to different inner cavity shapes. As long as the size of the storage part does not exceed the size that the smart anti-lost tool lock can accommodate, the tool lock can make corresponding internal storage cavity deformations. When the smart anti-lost tool lock is used later, only the tool shape set at the time of the initial setting can be placed in it. It can detect whether the object placed in the smart anti-lost tool lock is the required object to prevent impersonation.

The matching block 3 is deformed into a corresponding shape inside the lock box 1, and then the locking piece 4 is reinserted into the side of the lock box 1 and extends into the lock box 1. After the locking piece 4 hooks the matching block 3, even if the tool is taken out of the lock box 1, the matching block 3 is positioned in the position and will not rebound to the initial state (that is, the upper surfaces of all matching blocks 3 are at the same height). ), the locking piece 4 locks the position of the matching block 3 as a fixed recording function. After the tool is used, it is placed in the lock box 1 when the shape is set. The more matching blocks 3 there are and the smaller the single matching block 3 is, the more accurate the outer contour of the tool that can be fitted by the matching block 3 is. In actual use or manufacturing, a group of matching blocks 3 with corresponding fitting accuracy is produced according to the accuracy required by the use occasion. After the matching block 3 is squeezed into a certain contour shape, it only provides a storage cavity for the tool, and it cannot identify whether the tool has been placed. The signal board component 5 under the matching block 3 is used to determine whether the tool has been placed in the lock box 1. The signal board component 5 then transmits the information of whether the tool is in place to the device, which is received by the control center to count the return of the tool. This tool lock is used on multiple workstations in a production site, and all are connected to a control center using signal lines. When leaving get off work, the control center can directly obtain the return status of the tool remotely without the need to check one by one.

The partition 12 is provided with a plurality of through holes. The lower section of the block column 31 passes through the partition 12. The major diameter of the head of the block column 31 is greater than the major diameter of the lower section. A first spring 32 is provided between the head of the block column 31 and the partition 12. The first spring 32 is sleeved on the lower section of the block column 31. The lower section of the block column 31 is provided with a plurality of equidistant positioning ring grooves 311, as shown in FIG. Figure 5 , Figure 7 As shown, the lock plate 4 is provided with a plurality of cores 41 and lock ears 42. The core 41 is inserted into the positioning ring grooves 311 of equal height on two adjacent block columns 31. The lock ears 42 are located below the lock pin assembly 11. The lock ears 42 are provided with through holes, and the lock ears 42 through holes are located directly below the first lock pin 112. Figure 6 As shown, the matching block 3 also includes a signal column 33 and a second spring 34. The signal column 33 is divided into an upper section 331 and a lower section 332. The diameter of the upper section 331 is larger than that of the lower section 332. A vertical stepped through hole is provided in the block column 31. The signal column 33 is arranged in the block column 31. The second spring 34 is arranged between the bottom end surface of the upper section 331 and the stepped surface in the block column 31. The total length of the signal column 33 is greater than the total length of the block column 31. When the second spring 34 is in a relaxed state, the bottom of the signal column 33 is located in the block column 31; as shown in FIG. Fig. 9 As shown, the signal board assembly 5 includes a board body 51, a signal circuit board 52, a contact switch 53 and a reset spring 54. The board plane of the board body 51 is parallel to the upper and lower surfaces of the lock box 1. The board body 51 is provided with the same number of contact switches 53 as the matching blocks 3. The contact switches 53 are respectively located directly below each matching block 3. The contact switches 53 are arranged in grooves on the surface of the board body 51. The top of the contact switch 53 is lower than the upper surface of the board body 51, and the major diameter of the groove where the contact switch 53 is located is smaller than the bottom diameter of the block column 31; the contact switches 53 are respectively electrically connected to the signal circuit boards 52 inside the board body 51, the signal circuit boards 52 are electrically connected to the electrical interface 15, and the reset spring 54 is arranged between the board body 51 and the bottom plate 6.

[0036] The matching block 3 specifically achieves the contour fitting effect through the first spring 32 and the locking piece 4. When the matching block 3 is initially, the first springs 32 of all the matching blocks 3 are set to the same height position of the block column 31, the locking piece 4 is pulled out of the lock box 1, and the tool to be stored is placed in the lock box 1 to squeeze the matching block 3. Some of the first springs 32 are compressed, the block column 31 descends, and the lower section of the block column 31 is provided with a plurality of equidistant positioning ring grooves 311 which are the insertion grooves of the locking piece 4. The thickness of the tool put into the lock may change continuously, but we can slightly ignore a certain thickness difference and take the distance of the positioning ring grooves 311 as the minimum unit of height change of the matching block 3. The smaller the spacing of the positioning ring grooves 311, the finer the thickness fitting of the matching block 3 to the tool. The tool lock uses the total setting height range of the positioning ring grooves 311 on the block column 31 as the thickness range of the tool that can be placed. Within this thickness range, if Fig.10 As shown, different matching blocks 3 always have equal-height positioning ring grooves 311 for inserting the locking plate 4 for locking. The bottom of the block column 31 presses down the signal board assembly 5, but since the bottom of the block column 31 does not contact the contact switch 53 on the upper signal board assembly 5, the block column 31 does not give a signal whether the tool is in place. The contact switch 53 is squeezed by the signal column 33. The total length of the signal column 33 is slightly greater than the total length of the block column 31. When the second spring 34 is relaxed, the bottom of the signal column 33 is located in the block column 31. That is to say, when the tool is not in place, the bottom of the signal column 33 does not press the corresponding contact switch 53 below it. After the tool is placed in the lock box 1, the tool presses down the signal column 33, and the bottom of the signal column 33 also presses down the contact switch 53 below. The signal circuit board 52 gives the dot matrix signal corresponding to this tool and transmits it to the control center through the electrical interface 15 on the lock box 1. The signal board assembly 5 is similar to a "mechanical keyboard" with no key conflicts. Because the tool lock uses the matching block 3 to fit and store different types of tools, the thickness of these tools is different. Therefore, when changing the type of tool, the signal board assembly 5 should always be against the bottom end of the bottom block column 31. The reset spring 54 plays this role. Fig.11 As shown, a side plate groove 19 can also be provided on the top of the side of the lock box 1. The side plate groove 19 is away from the hinged side of the lock cover 2 of the lock box 1 and the side where the lock pin assembly 11 is located, preferably the raised side of the lock cover 2. The setting of the side plate groove 19 can facilitate long-handled tools (such as Fig.11 When placing the tool, you only need to put the tool head into the lock box 1 and lock it. The handle can be exposed, which is beneficial to reducing the size of the tool lock.

[0037] like Figure 7 , Figure 8As shown, a signal board terminal 55 is provided on the side of the plate body 51, and an electrode groove 14 is provided on the inner side wall of the lock box 1. The signal board terminal 55 is embedded in the electrode groove 14 and can slide up and down along the electrode groove 14; the signal circuit board 52 is electrically connected to the signal board terminal 55, and the electrode groove 14 is electrically connected to the electrical interface 15. The signal board assembly 5 and the electrical interface 15 need to be electrically connected. Since the height of the signal board assembly 5 may vary slightly according to the different tools stored in the tool lock, it is not suitable to directly use thin cables for electrical connection, because the height change may cause the thin cables to break or tangle; the signal board terminal 55 is provided on the side of the plate body 51, and the electrode groove 14 is provided on the inner side wall of the lock box 1, so that the electrical connection is in contact in the form of a sliding groove, which not only maintains sufficient sliding contact, but also eliminates the risk of cable entanglement or breakage.

[0038] The extension and retraction driving components of the first lock pin 112, the second lock pin 113 and the third lock pin 114 in the lock pin assembly 11 are electromagnetic contactors. The on and off power of the contactors can realize the short-range rapid extension and retraction of the first lock pin 112, the second lock pin 113 and the third lock pin 114. The electromagnetic contactors are used as the extension and retraction driving components, which are fast, accurate and reliable, and have a small structure size.

[0039] The first spring 32 and the second spring 34 are corrugated springs, which release elastic load more evenly and have smaller structural dimensions.

[0040] The groove side of the positioning ring groove 311 forms an acute angle with the horizontal plane. When the matching block 3 is pressed down, the positioning ring grooves 311 on different block columns 31 cannot automatically reach the same height position. If the side of the positioning ring groove 311 is perpendicular to the axis of the block column 31, then the locking piece 4 needs to be made thinner and the force of the tool pressing down the matching block 3 needs to be manually slightly adjusted when inserting the locking piece 4 so that the locking piece 4 is fully inserted, otherwise the insertion may be blocked. The groove side of the positioning ring groove 311 forms an acute angle with the horizontal plane, which has a guiding effect. The thickness of the locking piece 4 is equal to the vertical length of the bottom of the positioning ring groove 311. The locking piece 4 passes through one positioning ring groove 311 and then comes to the next positioning ring groove 311. The locking piece 4 contacts the groove side. Since the groove side is inclined, when the locking piece 4 is inserted into this positioning ring groove 311, this positioning ring groove 311 will continuously rise or fall so that the locking piece 4 is aligned with this groove.

[0041] The acute angle between the groove side surface of the positioning ring groove 311 and the horizontal plane is 15°.

[0042] A fixing plate 61 is provided on the side of the bottom plate 6, and bolt holes are provided on the fixing plate 61. The fixing plate 61 can facilitate the fixing of the tool lock at the work station.

[0043] When using this tool lock, fix the tool lock near the workstation where it is used, pull out the lock plate when the power is off, place the tools to be stored in it and press the lock cover, then insert the lock plate, connect the tool lock to the control center through the electrical interface, mark the wiring of the tool locks on different workstations, and complete the initial setting. During working hours, the user of this tool uses the fingerprint lock to open the lock cover to take the tool, put it back into the lock box and cover the lock cover before leaving get off work. When leaving work, the control center will obtain the return status of the tools at each workstation, mark the workstations where the tools have not been returned and feedback to the supervisor, and the tool locks where the tools have been returned will be remotely locked through the third lock pin.
