Description

Technical Field

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

[0002] An automotive steering gear, also known as a steering machine or a steering gear, is the most important component in the automotive 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 driving direction of an automobile, and it must meet the following requirements: safe and reliable operation, easy and flexible operation, appropriate steering force, smooth turning performance, and small impact transmitted from the road.

[0004] As the "nerve center" of the electronic control system of the steering gear, the performance of the PCB board terminal directly determines the steering assist accuracy, system reliability, and intelligent level. Moreover, the steering gear relies on modules such as sensors (torque, angle), controllers (ECUs), and motors to work together. The terminal realizes signal transmission and power distribution among multiple components through a standardized interface, 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 during terminal installation, generally, the terminal needs to be assembled inside the steering gear.

[0006] In the prior art, for example, in a Chinese patent with the application publication number CN111366100A and the name of an automatic assembly line for a steering gear assembly, the above patent discloses an automatic assembly line for an automotive steering gear assembly, including a mounting base 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 base inspection machine inspects the height of the connector on the mounting base, the height of the insertion piece, the inner hole of the connector, and the size of the through hole; the end cover assembly machine installs the end cover on the mounting base; the terminal assembly machine connects the connection terminal group to the mounting base so that the connection terminal is correspondingly connected to the connector.

[0007] Another example is a Chinese patent with the authorization announcement number CN202640208U and the name of a multi-hole positioning device for an automotive steering gear. The above patent discloses a multi-hole positioning device for an automotive steering gear, including a moving positioning plate, a positioning block, and a terminal plate. A groove is provided on the upper surface of the positioning block, and a terminal plate with a plurality of jacks is clamped in the groove. A probe is inserted into each jack, and the upper part of the probe extends outside the terminal plate. An energized copper sheet is sleeved on the upper end of each probe; at the same time, a plurality of positioning holes are opened on the surface of the moving positioning plate, and a sleeve positioning post is inserted into each positioning hole, and a positioning sleeve is installed at the bottom of the sleeve positioning post.

[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 bumps 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 part is arranged between the adjusting plate and the bearing frame. The elastic force of the elastic part can drive the fastening block away from the outer terminal while also driving the clamping bumps 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 an adaptation groove adapted to the fastening block is formed 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 adaptation 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 part is arranged between the locking block and the bearing frame bracket. A locking groove adapted to the locking block is formed on the adjusting plate, and the elastic force of the elastic positioning part 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 adaptation 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 adaptation 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 bumps 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 limiting block installed inside the bearing frame. A second reset spring is arranged between the limiting block and the bearing frame, and the limiting block is slidably connected to the mounting plate through a guiding unit.

[0019] Further, an unlocking part is arranged between the limiting 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. At the same time, during the process of the extended locking part sliding out of the fastening block, the fastening block is also unlocked.

[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 bumps 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 the clamping head is required 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 time, 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.

[0043] 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.

[0044] 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.

[0045] Specifically, the automotive terminal assembly device includes a frame 1 and two trays 3 mounted on the frame 1. One tray 3 stores external terminals 4, and the other tray 3 stores internal terminals 5. A steering gear body 7 is installed on the frame 1 through a conveying frame 6. Specifically, an installation 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. The external terminals 4 and the internal terminals 5 are both installed inside the cavity of the steering gear body 7. More specifically, the external terminals 4 and the internal terminals 5 are both sleeved outside the shaft body 72 to meet the working requirements of the subsequent steering gear body 7. More specifically, when the internal terminals 5 and the external terminals 4 are both installed inside the steering gear body 7, the internal terminals 5 are installed inside the external terminals 4. Moreover, during the installation process of the internal terminals 5 and the external terminals 4, the external terminals 4 are first installed inside the steering gear body 7, and then the internal terminals 5 are installed inside the cavity of the steering gear body 7. More specifically, the internal terminals 5 are installed inside the external terminals 4. A robotic arm for clamping the internal terminals 5 and the external terminals 4 is provided on the frame 1 for feeding the internal terminals 5 and the external terminals 4. This is prior art and will not be elaborated here.

[0046] A clamping head 8 is installed on the servo mechanism 2. The servo mechanism 2 can satisfy the movement of the clamping head 8 along the X-axis, Y-axis, and Z-axis, so as to realize the installation of the internal terminals 5 and the external terminals 4. A trigger clamping unit 10 for clamping the internal terminals 5 is installed inside the clamping head 8. The trigger clamping unit 10 can clamp and fix the internal terminals 5. When the clamping head 8 moves, the internal terminals 5 will be fed by the trigger clamping unit 10.

[0047] 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 blocks 12. When the clamping head 8 clamps the external terminal 4, the trigger clamping unit 10 contacts the external terminal 4, and at this moment, the trigger clamping unit 10 slides inside the clamping head 8, and during the retraction of the trigger clamping unit 10, the fastening blocks 12 are driven to fix the external terminal 4. More specifically, the cross-sectional view of the outer terminal 4 is in the shape of a step, so the inner side of the outer terminal 4 can be called a step. At this moment, when the clamping head 8 needs to be used to clamp the outer terminal 4, the clamping head 8 moves downward at this moment, so that the trigger clamping unit 10 abuts against the step inside the outer terminal 4. At this moment, when the clamping head 8 continues to be driven downward, the trigger clamping unit 10 will slide inside the clamping head 8, and the fastening block 12 will be driven to fix the outer terminal 4 during the retraction stroke of the trigger clamping unit 10, so that the clamping head 8 can clamp the outer terminal 4, and the servo mechanism 2 can be used to move the outer terminal 4 to the cavity on the steering gear body 7. After that, the clamping head 8 is used again, and the trigger clamping unit 10 on the clamping head 8 can clamp and fix the inner terminal 5. At this moment, when the clamping head 8 moves, the inner terminal 5 will be driven to load 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 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 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 realize 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 work efficiency and reduces the need for floor space. At the same time, it can also meet the needs of cost saving, which is suitable for later promotion and use.

[0048] In the embodiment provided by the present invention, the carrier frame 9 is installed inside the clamping head 8 through the positioning part 91. Specifically, the positioning part 91 includes a limit bar installed on the carrier frame 9, and a limit groove matching the limit bar is opened inside the clamping head 8. The limit bar is slidably connected in the limit groove, and a positioning spring 103 is arranged between the limit bar and the limit groove. The elastic force of the installation spring drives the carrier frame 9 to a predetermined position. The fastening block 12 is slidably connected to the carrier frame 9 through the adjustment plate 11, so that the stability of the fastening block 12 when sliding can be improved. When the adjustment plate 11 slides, it will drive the fastening block 12 to slide together, meeting the needs of later work.

[0049] 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 provided on the mounting plate 101. Specifically, the clamping protrusion 104 abuts against the upper half of the inner terminal 5. An extrusion part is provided 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 cooperation with the extrusion groove 107. An elastic member 13 is provided between the adjusting plate 11 and the carrier 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 carrier frame 9, and the elastic force of the elastic member 13 drives the adjusting plate 11 to be located inside the carrier frame 9, that is, at this moment the fastening block 12 is in a state of retracting inside the carrier 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, through 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.

[0050] 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 provided 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 carrier 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.

[0051] Specifically, when it is necessary to fix the outer terminal 4, at this time, the clamping head 8 moves downward 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. During the retraction stroke of the trigger clamping unit 10, under the cooperation of the pressing block and the pressing 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.

[0052] In the embodiment provided by the present invention, a locking mechanism 14 is provided 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 provided 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 provided 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 is driven to slide inside the bearing frame 9 through the cooperation of the pressing block and the pressing 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.

[0053] In the embodiments provided by the present invention, a separation part 15 is further provided between the bearing frame 9 and the fastening block 12. Specifically, the separation part 15 includes a pressing block 151 provided on the clamping head 8, and a pressing groove 152 is formed in the fastening block 12, and the pressing block 151 is in abutting cooperation with the pressing groove 152. The separation part 15 drives the fastening block 12 to slide out of the corresponding fitting groove 41. An extended locking part 145 is further provided between the fastening block 12 and the locking block 141. Specifically, the extended locking part 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. When the fastening block 12 slides out of the corresponding fitting groove 41, the extended locking part 145 fixes the fastening block 12. A triggering clamping rod 102 is slidably connected inside the mounting plate 101, a positioning spring 103 is provided between the triggering clamping rod 102 and the mounting plate 101, and a clamping convex block 104 is mounted on the triggering 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 triggering clamping rod 102 at this moment will slide inside the mounting plate 101, thereby squeezing the positioning spring 103. That is, when the triggering 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.

[0054] In the embodiment provided by the present invention, a reset unit 16 is provided 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 provided between the limiting block 161 and the clamping head 8. And the limiting block 161 is slidably connected to 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 satisfy 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.

[0055] 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 portion 17 is provided 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 portion 17. After unlocking the adjusting plate 11, it also unlocks the fastening block 12 during the stroke of the extended locking portion 145 sliding out of the fastening block 12. The unlocking portion 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 extended block 1451 to slide out of the corresponding positioning groove 1453 together, and also unlock the fastening block 12, thereby meeting the need to fix the outer terminal 4 next time.

[0056] In the embodiment provided by the present invention, a contact unit is further provided 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 protrusion 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, where 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 inner terminal 5 needs to be fixed using the clamping head 8, and then the inner terminal 5 is installed inside the steering gear body 7 again. When the clamping head 8 moves the inner terminal 5 downward by a certain stroke, at this moment, the wedge-shaped groove 105 on the trigger clamping rod 102 will abut against the contact portion 106, causing the mounting plate 101 to slide away from the inner terminal 5, that is, the clamping protrusion 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 requirements, so that when the wedge-shaped groove 105 at the bottom of the trigger clamping rod 102 abuts against the contact portion 106 and the clamping protrusion 104 separates 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 protrusion 104 separates 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 protrusion 104 cannot fix the inner terminal 5 again, so the inner terminal 5 will not be taken out, thus meeting the installation requirements of the inner terminal 5 and the outer terminal 4.

[0057] In another embodiment provided by the present invention, more specifically, an extrusion mechanism is provided 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 prior art, and its structure and working principle will not be elaborated here.

[0058] In the embodiment provided by the present invention, various springs mentioned above can select the length, elastic coefficient, etc. of the spring according to the work, and the installation method of the spring is also prior art, which will not be elaborated here.

[0059] It should be noted that the electrical equipment involved in this application can be powered by a storage battery or an external power supply.
