Description

Technical Field

[0001] The invention relates to the technical field of terminal assembly, in particular to an automobile terminal assembly device. Background Art

[0002] The automobile steering gear, also known as the steering machine or steering gear, is the most important component in the automobile steering system. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission.

[0003] More specifically, the function of the steering gear is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. The steering device is a device that controls the direction of the car's travel. It must meet the following requirements: safe and reliable operation, light and flexible operation, appropriate steering force, smooth turning performance and small impact from the road.

[0004] PCB terminals are the "nerve hub" of the steering gear electronic control system. Their performance directly determines the steering power accuracy, system reliability and intelligence level. The steering gear relies on sensors (torque, angle), controllers (ECU), motors and other modules to work together. Terminals realize signal transmission and power distribution among multiple components through standardized interfaces, avoiding interference or failures caused by messy wiring harnesses.

[0005] It can be seen that in order to meet the working requirements of the steering gear and the stability of the terminal during installation, it is generally necessary to assemble the terminal inside the steering gear.

[0006] In the prior art, there is a Chinese patent with application publication number CN111366100A, entitled "An automatic assembly line for a steering gear assembly". The patent discloses an automatic assembly line for an automobile steering gear assembly, including a mounting seat inspection machine, an end cover assembly machine, a terminal assembly machine, an inductor assembly machine, a capacitor assembly machine, a characteristic inspection machine and a coating machine. The mounting seat inspection machine inspects the height of the connector on the mounting seat, the height of the plug-in piece, and the size of the inner hole and the through hole of the connector; the end cover assembly machine installs the end cover on the mounting seat; and the terminal assembly machine connects the connecting terminal to the mounting seat so that the connecting terminal is connected to the connector correspondingly.

[0007] Another example is a Chinese patent with authorization announcement number CN202640208U, entitled "A multi-hole positioning device for an automobile steering gear". The above patent discloses a multi-hole positioning device for an automobile steering gear, including a motion positioning plate, a positioning block, and a terminal plate. A groove is arranged on the upper surface of the positioning block, and a terminal plate with a plurality of sockets is inserted into the groove. A probe is inserted into each socket, and the upper part of the probe extends out of the terminal board, and an energized copper sheet is inserted into the upper end of each probe. At the same time, a plurality of positioning holes are arranged on the surface of the motion positioning plate, and a sleeve positioning column is inserted into each positioning hole, and a positioning sleeve is installed at the bottom of the sleeve positioning column.

[0008] In the prior art, such as the above-mentioned patent, the need for the terminal to be installed inside the steering gear can be met to a certain extent. However, it is known that there are generally two terminals inside the steering gear, namely the positive terminal of the motor and the negative terminal of the motor, which are respectively installed on the positive and negative poles of the motor to meet the motor drive needs. It is known that the positive terminal and the negative terminal in the prior art are of different sizes. Therefore, during the installation process, the steering gear is fixed by a fixed frame, and then the positive terminal of the motor is clamped by different adsorption clamping mechanisms, and the positive terminal is driven to move to the steering gear position by a servo mechanism, and the positive terminal is installed inside the steering gear. After that, the steering gear is disassembled from the fixed frame and refixed to another set of equipment, the steering gear is fixed again, and the installation method of the positive terminal is repeated in the set of equipment, and the negative terminal is installed inside the steering gear, and the installation efficiency is low. Of course, in order to improve the work efficiency to a certain extent, the two sets of equipment are connected through a production line, and after the positive terminal is installed, it is transported to the next equipment to realize the installation of the negative terminal, but the above operation process still requires two separate sets of equipment to realize the installation of the steering gear terminal, resulting in an increase in production costs.

[0009] It can be seen that when the positive terminal and the negative terminal are of different sizes, how a clamping mechanism on a device can clamp and load the positive terminal while also loading the negative terminal is a technical problem that needs to be solved urgently. Summary of the invention

[0010] The object of the present invention is to provide an automobile terminal assembly device to solve the problems raised in the above background technology.

[0011] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automobile terminal assembly device, comprising a frame and two trays installed on the frame, one tray storing external terminals, and the other tray storing internal terminals, and a steering gear body is installed on the frame through a conveyor frame, and a servo mechanism is arranged on the frame, a clamping head is installed on the servo mechanism, a trigger clamping unit for clamping the internal terminal is installed inside the clamping head, a plurality of fastening blocks are slidably connected inside the clamping head, and the trigger clamping unit is transmission-connected with the fastening block; when the clamping head clamps the external terminal, the trigger clamping unit drives the fastening block to fix the external terminal during the retraction stroke.

[0012] Furthermore, a bearing frame is installed inside the clamping head through a positioning portion, and the fastening block is slidably connected to the bearing frame through an adjustment plate.

[0013] Further, the trigger clamping unit includes a mounting plate installed inside the clamping head, and clamping protrusions for clamping the inner terminal are arranged on the mounting plate; an extrusion part is arranged between the mounting plate and the adjusting plate, and an elastic member is arranged between the adjusting plate and the bearing frame. The elastic force of the elastic member can drive the fastening block away from the outer terminal while also driving the clamping protrusions to abut against the outer side of the inner terminal to fix the inner terminal.

[0014] Further, the fastening block is slidably connected to the adjusting plate through a connecting unit, and a fitting groove adapted to the fastening block is opened inside the outer terminal. When the trigger clamping unit moves upward, the adjusting plate is driven to slide in the bearing frame through the extrusion part so that the fastening block is clamped in the fitting groove.

[0015] Further, a locking mechanism is arranged between the adjusting plate and the bearing frame. The locking mechanism includes a locking block slidably connected inside the bearing frame, and an elastic positioning member is arranged between the locking block and the bearing frame bracket. A locking groove adapted to the locking block is opened on the adjusting plate, and the elastic force of the elastic positioning member drives the locking block to be clamped in the locking groove.

[0016] Further, a separating part is also arranged between the bearing frame and the fastening block. The separating part drives the fastening block to slide out of the corresponding fitting groove. An extended locking part is also arranged between the fastening block and the locking block. When the fastening block slides out of the corresponding fitting groove, the extended locking part fixes the fastening block.

[0017] Further, a trigger clamping rod is slidably connected inside the mounting plate. A positioning spring is arranged between the trigger clamping rod and the mounting plate, and the clamping protrusions are installed on the trigger clamping rod.

[0018] Further, a reset unit is arranged between the mounting plate and the clamping head. The reset unit includes a limit block installed inside the bearing frame. A second reset spring is arranged between the limit block and the bearing frame, and the limit block is slidably connected to the mounting plate through a guiding unit.

[0019] Further, an unlocking part is arranged between the limit block and the unlocking block. After the trigger clamping unit moves away from the outer terminal, during the process of the reset unit driving the mounting plate to reset, the unlocking part drives the locking block to slide out of the corresponding locking groove, unlocking the adjusting plate and also unlocking the extended locking part from the fastening block during the process of the extended locking part sliding out of the fastening block.

[0020] Further, a contact unit is also arranged between the trigger clamping rod and the outer terminal. When the trigger clamping rod abuts against the contact unit, the clamping protrusions move away from the inner terminal to unlock the inner terminal.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: for this automotive terminal assembly device, when it is necessary to use the clamping head to clamp the outer terminal at this moment, the clamping head moves downward so that the triggering clamping unit abuts against the stepped platform inside the outer terminal. When the clamping head is continuously driven downward, the triggering clamping unit will slide into the clamping head. During the retraction stroke of the triggering clamping unit, the fastening block is driven to fix the outer terminal, thus realizing the clamping of the outer terminal by the clamping head. Then, the outer terminal can be moved to the cavity on the steering gear body through the servo mechanism. After that, when the clamping head is used again, the triggering clamping unit on the clamping head can clamp and fix the inner terminal. When the clamping head moves, the inner terminal will be fed by driving the triggering clamping unit.

[0022] Therefore, this clamping head can realize the assembly of the inner terminal and the outer terminal when their sizes are different. At this moment, there is no need to use two devices to separately drive the feeding of the inner terminal and the outer terminal. Therefore, this clamping head can passively change the clamping state according to the shapes of the inner terminal and the outer terminal to realize the clamping and fixing of the inner terminal and the outer terminal. Furthermore, the feeding of the inner terminal and the outer terminal can be realized on one device, which greatly improves the working efficiency, reduces the required floor area, and can also meet the cost-saving requirement, making it suitable for later popularization and use.

Detailed implementation manners

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 - 18 The present invention provides a technical solution: an automobile terminal assembly device, comprising a frame 1 and two trays 3 installed on the frame 1, one tray 3 stores external terminals 4, the other tray 3 stores internal terminals 5, and a steering gear body 7 is installed on the frame 1 through a conveying frame 6, and a servo mechanism 2 is arranged on the frame, a clamping head 8 is installed on the servo mechanism 2, a trigger clamping unit 10 for clamping the internal terminal 5 is installed inside the clamping head 8, a plurality of fastening blocks 12 are slidably connected inside the clamping head 8, and the trigger clamping unit 10 is transmission-connected with the fastening block 12; when the clamping head 8 clamps the external terminal 4, the trigger clamping unit 10 drives the fastening block 12 to fix the external terminal 4 during the retraction stroke.

[0028] Specifically, the automobile terminal assembly device includes a frame 1 and two trays 3 installed on the frame 1, one tray 3 stores an outer terminal 4, the other tray 3 stores an inner terminal 5, and a steering gear body 7 is installed on the frame 1 through a conveyor frame 6. Specifically, a mounting cavity 71 is provided on the steering gear body 7, and a shaft body 72 is installed inside the cavity of the steering gear body 7, wherein the outer terminal 4 and the inner terminal 5 are both installed inside the cavity of the steering gear body 7, more specifically, the outer terminal 4 and the inner terminal 5 are both sleeved on the outside of the shaft body 72 to meet the working needs of the steering gear body 7 in the later stage. More specifically, when the inner terminal 5 and the outer terminal 4 are both installed inside the steering gear body 7, the inner terminal 5 is installed inside the outer terminal 4. Moreover, during the installation process of the inner terminal 5 and the outer terminal 4, the outer terminal 4 is first installed inside the steering gear body 7, and then the inner terminal 5 is installed inside the cavity of the steering gear body 7, more specifically, the inner terminal 5 is installed inside the outer terminal 4. A mechanical arm for clamping the inner terminal 5 and the outer terminal 4 is arranged on the frame 1 and is used for loading the inner terminal 5 and the outer terminal 4. This is the prior art and will not be described in detail here.

[0029] The servo mechanism 2 is provided with a clamping head 8, which can move along the X-axis, Y-axis and Z-axis to realize the installation of the inner terminal 5 and the outer terminal 4. A trigger clamping unit 10 for clamping the inner terminal 5 is installed inside the clamping head 8, wherein the trigger clamping unit 10 can clamp and fix the inner terminal 5. When the clamping head 8 moves, the inner terminal 5 is driven to be loaded through the trigger clamping unit 10.

[0030] Inside the clamping head 8, a plurality of fastening blocks 12 are slidably connected, and the trigger clamping unit 10 is drivingly connected to the fastening blocks 12. When the clamping head 8 clamps the outer terminal 4, the trigger clamping unit 10 contacts the outer terminal 4. At this moment, the trigger clamping unit 10 will slide inside the clamping head 8, and the fastening blocks 12 will be driven to fix the outer terminal 4 during the retraction stroke of the trigger clamping unit 10. More specifically, the cross-sectional view of the outer terminal 4 is in a stepped shape. Therefore, the inner side of the outer terminal 4 can be called a stepped platform. At this time, when the clamping head 8 needs to clamp the outer terminal 4, the clamping head 8 moves downward so that the trigger clamping unit 10 abuts against the stepped platform inside the outer terminal 4. At this time, when the clamping head 8 is continuously driven to move downward, the trigger clamping unit 10 will slide into the clamping head 8, and the fastening blocks 12 will be driven to fix the outer terminal 4 during the retraction stroke of the trigger clamping unit 10, thus realizing the clamping of the outer terminal 4 by the clamping head 8. Then, the outer terminal 4 can be moved to the cavity on the steering gear body 7 through the servo mechanism 2. After that, when the clamping head 8 is used again, the trigger clamping unit 10 on the clamping head 8 can clamp and fix the inner terminal 5. At this time, when the clamping head 8 moves, the inner terminal 5 will be fed by the trigger clamping unit 10. Therefore, the clamping head 8 can realize the assembly of the inner terminal 5 and the outer terminal 4 even when the sizes of the inner terminal 5 and the outer terminal 4 are different. At this time, there is no need to use two devices to drive the inner terminal 5 and the outer terminal 4 to feed materials respectively. Therefore, the clamping head can passively change the clamping state according to the shapes of the inner terminal 5 and the outer terminal 4 to realize the clamping and fixing of the inner terminal 5 and the outer terminal 4 and the feeding of the terminals. At this time, the feeding of the inner terminal 5 and the outer terminal 4 is realized on one device, which greatly improves the working efficiency, reduces the required floor area, and can also meet the need of cost saving, making it suitable for later popularization and use.

[0031] In the embodiment provided by the present invention, a carrier frame 9 is installed inside the clamping head 8 through a positioning portion 91. Specifically, the positioning portion 91 includes a limiting strip installed on the carrier frame 9, and a limiting groove adapted to the limiting strip is formed inside the clamping head 8. The limiting strip is slidably connected in the limiting groove, and a positioning spring 103 is arranged between the limiting strip and the limiting groove. The elastic force of the installed spring drives the carrier frame 9 to be in a predetermined position. And the fastening block 12 is slidably connected to the carrier frame 9 through an adjusting plate 11, so the stability of the fastening block 12 during sliding can be improved. When the adjusting plate 11 slides, the fastening block 12 will be driven to slide together to meet the needs of later work.

[0032] In the embodiments provided by the present invention, the triggering clamping unit 10 includes a mounting plate 101 installed inside the clamping head 8. A clamping protrusion 104 for clamping the inner terminal 5 is arranged on the mounting plate 101. Specifically, the clamping protrusion 104 abuts against the upper half of the inner terminal 5. An extrusion part is arranged between the mounting plate 101 and the adjusting plate 11. The extrusion part includes an extrusion block fixedly connected to the mounting plate 101. An extrusion groove 107 adapted to the extrusion block is formed at the bottom of the adjusting plate 11, and the extrusion block is in abutting fit with the extrusion groove 107. An elastic member 13 is arranged between the adjusting plate 11 and the carrying frame 9. The elastic force of the elastic member 13 can drive the fastening block 12 away from the outer terminal 4 and at the same time can also drive the clamping protrusion 104 to abut against the outer side of the inner terminal 5 to fix the inner terminal 5. Specifically, the elastic member 13 is a prior art, which includes an elastic telescopic rod installed between the adjusting plate 11 and the carrying frame 9, and the elastic force of the elastic member 13 drives the adjusting plate 11 to be located inside the carrying frame 9, that is, at this moment the fastening block 12 is in a state of retracting inside the carrying frame 9. More specifically, without external force, the extrusion block on the mounting plate 101 is located inside the extrusion groove 107. Under the action of the elastic member 13 and the cooperation between the extrusion groove 107 and the extrusion block, the clamping protrusion 104 on the mounting plate 101 abuts against the inner terminal 5 to fix the inner terminal 5, so as to meet the feeding requirement of the inner terminal 5.

[0033] In the embodiments provided by the present invention, the fastening block 12 is slidably connected to the adjusting plate 11 through a connecting unit. Specifically, the connecting unit includes an extension end 121 fixedly connected to the fastening block 12. A first return spring 122 is arranged between the extension end 121 and the adjusting plate 11, and the elastic force of the first return spring 122 drives the fastening block 12 away from the adjusting plate 11. An adaptation groove 41 adapted to the fastening block 12 is formed inside the outer terminal 4. Specifically, this adaptation groove 41 is for the later installation requirement of the outer terminal 4. More specifically, when the triggering clamping unit 10 moves upward, the adjusting plate 11 is driven to slide inside the carrying frame 9 through the extrusion part, so that the fastening block 12 is clamped in the adaptation groove 41. Preferably, there is sufficient friction between the fastening block 12 and the adaptation groove 41. When the fastening block 12 is clamped in the adaptation groove 41, the fastening block can drive the outer terminal 4 to move together. Of course, if the outer terminal 4 is installed in a fixed position, at this time the outer terminal 4 does not move. When the external force for driving the fastening block 12 to slide out of the adaptation groove 41 where it is located is greater than the friction force, at this moment the fastening block 12 can be separated from the outer terminal 4, that is, it is convenient for the unloading of the outer terminal 4.

[0034] Specifically, when it is necessary to fix the outer terminal 4, the clamping head 8 moves downward at this time, so that the trigger clamping unit 10 abuts against the step inside the outer terminal 4. When the clamping head 8 is continuously driven to move downward, the trigger clamping unit 10 will slide into the clamping head 8 at this time. During the retraction stroke of the trigger clamping unit 10, under the cooperation of the extrusion block and the extrusion groove 107, the adjusting plate 11 is driven to slide inside the bearing frame 9, so that the adjusting plate 11 drives the fastening block 12 to slide inside the bearing frame 9, and then the fastening block 12 can be driven to fix the outer terminal 4, thus realizing the clamping and fixing of the outer terminal 4 by the clamping head 8.

[0035] In the embodiment provided by the present invention, a locking mechanism 14 is arranged between the adjusting plate 11 and the bearing frame 9. The locking mechanism 14 includes a locking block 141 slidably connected inside the bearing frame 9, and an elastic positioning member is arranged between the locking block 141 and the bearing frame 9. Specifically, the elastic positioning member includes an extension plate 142 fixedly connected to the locking block 141, and a first locking spring 143 is arranged between the extension plate 142 and the bearing frame 9. A locking groove 144 adapted to the locking block 141 is formed on the adjusting plate 11, and the elastic force of the elastic positioning member drives the locking block 141 to be clamped in the locking groove 144. That is, when the mounting plate 101 moves upward, the adjusting plate 11 will be driven to slide inside the bearing frame 9 through the cooperation of the extrusion block and the extrusion groove 107, so that the adjusting plate 11 drives the fastening block 12 to slide inside the bearing frame 9, and then the fastening block 12 can be driven to fix the outer terminal 4. During the sliding stroke of the adjusting plate 11 inside the bearing frame 9, the locking block 141 will slide in the chute until the locking block 141 is clamped inside the locking groove 144. At this moment, the state of the adjusting plate 11 can be fixed, thereby improving the stability during the installation of the outer terminal 4.

[0036] In the embodiments provided by the present invention, a detachment portion 15 is further provided between the bearing frame 9 and the fastening block 12. Specifically, the detachment portion 15 includes a pressing block 151 provided on the clamping head 8, and a pressing groove 152 is formed in the fastening block 12, wherein the pressing block 151 is in abutting cooperation with the pressing groove 152. The detachment portion 15 drives the fastening block 12 to slide out of the corresponding fitting groove 41. An extended locking portion 145 is further provided between the fastening block 12 and the locking block 141. Specifically, the extended locking portion 145 includes an extended block 1451 slidably connected inside the locking block 141, and a second locking spring 1452 is provided between the extended block 1451 and the locking block 141. During the process of the fastening block 12 sliding out of the corresponding fitting groove 41 inside, the extended locking portion 145 fixes the fastening block 12. A trigger clamping rod 102 is slidably connected inside the mounting plate 101, a positioning spring 103 is provided between the trigger clamping rod 102 and the mounting plate 101, and a clamping convex block 104 is mounted on the trigger clamping rod 102. When the clamping head 8 carries the external terminal 4 and is installed into the cavity of the steering gear body 7, the external terminal 4 needs to be separated from the clamping head 8. During this process, after the external terminal 4 is installed in the cavity of the steering gear body 7, the clamping head 8 is continuously driven to move downward. During the downward movement of the clamping head 8, the pressing block on the mounting plate 101 has already abutted against the bottom of the pressing groove 107, and the mounting plate 101 cannot move upward. When the clamping head 8 continues to move downward, the trigger clamping rod 102 at this moment will slide inside the mounting plate 101, thereby squeezing the positioning spring 103. That is, when the trigger clamping rod 102 slides inside the mounting plate 101, the clamping head 8 can still move downward for a certain distance at this moment, and the pressing block 151 will abut against the pressing groove 152, so that the fastening block 12 slides inside the adjusting plate 11 after overcoming the elastic force of the first return spring 122. During the sliding process of the fastening block 12, the elastic force of the second locking spring 1452 drives the extended block 1451 to be clamped in the positioning groove 1453. At this time, the fastening block 12 has slid out of the corresponding fitting groove 41 on the external terminal 4. By clamping the extended block 1451 inside the positioning groove 1453, the state of the fastening block 12 is fixed, avoiding the fastening block 12 from affecting the installation and use of the external terminal 4.

[0037] In the embodiment provided by the present invention, a reset unit 16 is arranged between the mounting plate 101 and the clamping head 8. The reset unit 16 includes a limiting block 161 installed inside the bearing frame 9. A second reset spring 162 is arranged between the limiting block 161 and the clamping head 8. And the limiting block 161 is slidably connected with the mounting plate 101 through a guiding unit 163. The guiding unit 163 includes a positioning block fixedly connected to the limiting block 161. A guiding groove adapted to the positioning block is formed on the mounting plate 101, so as to meet the installation of the limiting block 161 and the mounting plate 101. That is, when the clamping unit 10 is triggered to abut against the inner terminal 5, the positioning block will slide inside the guiding groove, triggering the clamping unit 10 to fix the inner terminal 5, thereby improving the stability when the clamping unit 10 slides.

[0038] In the embodiment provided by the present invention, after the outer terminal 4 is installed inside the cavity of the steering gear body 7, at this moment, the clamping head 8 will move upward. During the upward movement of the clamping head 8, the triggering clamping rod 102 will gradually move away from the outer terminal 4. When the triggering clamping unit 10 completely slides out of the outer terminal 4, during the process of the reset unit 16 restoring the elastic deformation, it drives the mounting plate 101 to move downward. An unlocking part 17 is arranged between the limiting block 161 and the unlocking block 173. After the triggering clamping unit 10 moves away from the outer terminal 4, during the stroke of the reset unit 16 driving the mounting plate 101 to reset, it drives the locking block 141 to slide out of the corresponding locking groove 144 through the unlocking part 17. After unlocking the adjusting plate 11, it also unlocks the fastening block 12 during the stroke of the extended locking part 145 sliding out of the fastening block 12. The unlocking part 17 includes an unlocking rod 171 fixedly connected to the limiting block 161. An unlocking block 173 is fixedly connected to the unlocking rod 171. And an unlocking groove 172 adapted to the unlocking block 173 is formed on the extension plate 142. Therefore, when the fastening block 12 moves downward, through the cooperation of the unlocking rod 171 and the unlocking block 173, it drives the unlocking block 173 to abut against the unlocking groove 172, so as to drive the unlocking block 173 to drive the extension plate 142 to slide inside the bearing frame 9, so that the locking block 141 slides out of the corresponding locking groove 144. And when the locking block 141 slides, it will drive the extension block 1451 to slide out of the corresponding positioning groove 1453 together, and also unlock the fastening block 12, thus meeting the need for fixing the outer terminal 4 next time.

[0039] In the embodiment provided by the present invention, a contact unit is further arranged between the trigger clamping rod 102 and the outer terminal 4. When the trigger clamping rod 102 abuts against the contact unit during the stroke, the clamping lug 104 moves away from the inner terminal 5 to unlock the inner terminal 5. Specifically, the contact unit includes a contact portion 106 fixedly connected inside the outer terminal 4, wherein the contact portion 106 is inclined and does not affect the subsequent use of the inner terminal 5 and the outer terminal 4. A wedge-shaped groove 105 is formed at the bottom of the trigger clamping rod 102. After the outer terminal 4 is installed inside the installation cavity 71 of the steering gear body 7, the clamping head 8 is used to fix the inner terminal 5, and then the inner terminal 5 is installed inside the steering gear body 7 again. When the clamping head 8 carries the inner terminal 5 and moves downward for a certain stroke, the wedge-shaped groove 105 on the trigger clamping rod 102 will abut against the contact portion 106 at this moment, so that the mounting plate 101 slides away from the inner terminal 5, that is, the clamping lug 104 will move away from the inner terminal 5, and the inner terminal 5 is placed inside the outer terminal 4. More specifically, the length of the trigger clamping rod 102 is designed according to the working needs, so that when the wedge-shaped groove 105 at the bottom of the trigger clamping rod 102 abuts against the contact portion 106, and when the clamping lug 104 is separated from the inner terminal 5, there is still a certain height difference between the inner terminal 5 and the outer terminal 4, that is, when the clamping lug 104 is separated from the inner terminal 5, the inner terminal 5 will fall inside the outer terminal 4. Therefore, when the clamping head 8 resets upward after the installation of the inner terminal 5 is completed, due to the height difference between the inner terminal 5 and the outer terminal 4, the inner terminal 5 will fall inside the outer terminal 4 after being unlocked, and the clamping lug 104 cannot fix the inner terminal 5 again, so the inner terminal 5 will not be taken out, thus meeting the installation needs of the inner terminal 5 and the outer terminal 4.

[0040] In another embodiment provided by the present invention, more specifically, an extrusion mechanism is arranged on the frame 1, that is, after the outer terminal 4 and the inner terminal 5 are both installed inside the installation cavity 71 of the steering gear body 7, the extrusion mechanism is used to press the inner terminal 5 and the outer terminal 4 tightly. This is the prior art, and its structure and working principle will not be elaborated here.

[0041] In the embodiment provided by the present invention, the above various springs can select the length, elastic coefficient, etc. of the springs according to the work, and the installation method of the springs is also the prior art, which will not be elaborated here.

[0042] It should be noted that the electrical equipment involved in this application can be powered by a storage battery or an external power supply.
