[0002] A coupler generally includes a male terminal and a female terminal. The male coupler and the female coupler are respectively connected to both ends of different circuits. The male coupler is provided with a plurality of pins, and the female coupler is provided with sockets that can be arranged corresponding to the pins. When the male coupler is plugged into the female coupler, the pins are inserted into the corresponding sockets, thereby realizing the connection of the two circuits.

[0003] After retrieval, the patent with the publication number CN202322008130.7 discloses "a coupler", which includes a male coupler and a female coupler.

The first conductive member includes a first pin, an intermediate connecting member, and a second pin that are integrally bent and connected in sequence.

[0004] However, in the use of the above coupler, there is a lack of an automatic alignment mechanism, so it is easy to occur misalignment or deviation during the crimping process, resulting in crimping failure or large plugging wear, thus affecting the crimping quality of the coupler. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that in the prior art, there is a lack of an automatic alignment mechanism, so it is easy to occur misalignment or deviation during the crimping process, resulting in crimping failure or large plugging wear, thus affecting the crimping quality of the coupler, and to propose a coupler terminal crimping device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A coupler terminal crimping device includes a frame. A fixed frame is fixedly installed on the left side of the upper end of the frame. A movable frame is slidably installed on the right side of the fixed frame at the upper end of the frame. A female terminal is clamped at the upper end of the fixed frame, and a male terminal is clamped at the upper end of the movable frame. An electric push rod is fixedly installed at the right end of the movable frame, and the right end of the electric push rod is fixedly installed on the frame;

[0008] It also is provided with a crimping mechanism for crimping the female terminal and the male terminal. The crimping mechanism includes a first inclined fixed block movably inserted at the front ends of the female terminal and the male terminal. A first connecting rod is fixedly installed at the front end of each first inclined fixed block. The front ends of the two first connecting rods on both sides respectively penetrate and are slidably installed on the fixed frame and the movable frame, and a first spring is sleeved on the outer side of each first connecting rod;

[0009] There is also a stabilizing mechanism for the stable crimping of the female terminal and the tapping terminal. The stabilizing mechanism includes a telescopic rod symmetrically and fixedly installed between the fixed frame and the movable frame before and after. A cleaning ring is fitted and abutted at the middle connection of the telescopic rod, and fixing rings are fixedly installed on the outer sides of the cleaning rings.

[0010] Preferably, fixing groove blocks are symmetrically and fixedly installed at the front and rear ends of the left end of the tapping terminal, and inclined fixing blocks two are slidably installed on the corresponding fixing groove blocks at the front and rear ends of the female terminal. Spring two are fixedly installed at the upper ends of the inclined fixing blocks two, and the upper ends of the spring two are fixedly installed on the female terminal.

[0011] Preferably, limiting inclined blocks are slidably installed on the corresponding inclined fixing blocks two at the front and rear ends of the female terminal. Spring three are fixedly installed at the left ends of the limiting inclined blocks, and the left ends of the spring three are fixedly installed on the female terminal.

[0012] Preferably, limiting rods are inserted at the upper ends of the limiting inclined blocks, and the mutually approaching ends of the limiting rods are slidably connected to the female terminal.

[0013] Preferably, a slot is provided on the right end of the female terminal corresponding to the tapping terminal. Through slots are symmetrically opened at the front and rear of the female terminal corresponding to the slot, and protective plates are fixedly installed at the lower ends of the limiting inclined blocks corresponding to the through slots.

[0014] Preferably, a nozzle pipe is provided on the front side of the female terminal corresponding to the through slot. An air bag is communicated with the upper end of the nozzle pipe, and the left end of the air bag is fixedly connected to the fixed frame.

[0015] Preferably, a pressing plate is fixedly installed at the right end of the air bag, and a top bar is fixedly installed on the left end of the movable frame corresponding to the pressing plate.

[0016] Preferably, link rods two are symmetrically and fixedly installed at the front and rear ends of the left end of the pressing plate. The left ends of the link rods two penetrate and are slidably installed on the fixed frame, and spring four are sleeved on the outer sides of the link rods two.

[0017] Preferably, support blocks are slidably installed on the outer sides of the fixing rings. The support blocks are fixedly connected to the outer tube of the telescopic rod, and spring five are fixedly installed at the upper ends of the support blocks. The upper ends of the spring five are fixedly connected to the fixing rings.

[0018] Preferably, magnetic blocks one are fixedly installed at the lower sides of the left ends of the fixing rings, and no less than five magnetic blocks two are equidistantly fixedly installed on the upper end of the frame at the sides away from each other of the magnetic blocks one.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the present invention, the female terminal and the male terminal are respectively pressed onto the fixed frame and the movable frame from the upper ends of the fixed frame and the movable frame. Since the inclined surface at the upper end of the first inclined fixing block is subjected to the extrusion force of the female terminal and the male terminal, it will drive the first connecting rod to slide forward, compress the first spring. Until the lower ends of the female terminal and the male terminal respectively fit against the inner bottom ends of the fixed frame and the movable frame, the first inclined fixing block and the first connecting rod will slide backward and reset under the action of the first spring, so that the first inclined fixing block is respectively inserted onto the female terminal and the male terminal, facilitating the automatic fixing of the female terminal and the male terminal, improving the crimping efficiency, and automatically aligning and adjusting the crimping horizontal angle of the female terminal and the male terminal to ensure the subsequent crimping quality.

[0021] 2. In the present invention, when the electric push rod is started to drive the movable frame to slide towards the fixed frame, the movable frame will drive the male terminal to approach the female terminal synchronously until the conductive head of the male terminal is successfully inserted into the slot of the female terminal. At the same time, the male terminal will also drive the fixed groove blocks on both sides to move leftward synchronously. The fixed groove blocks will gradually contact the inclined surface of the second inclined fixing block and extrude the inclined surface of the second inclined fixing block, pushing the second inclined fixing block to slide upward on the female terminal, compressing the second spring. Until the fixing groove at the upper end of the fixed groove block crosses the lower end of the second inclined fixing block, under the action of the second spring, the second inclined fixing block is pushed to slide downward and is clamped on the fixed groove block. At this time, the male terminal is also exactly completely inserted onto the female terminal, and the electric push rod stops pushing the movable frame further, completing the crimping work between the male terminal and the female terminal. The cooperation between the set fixed groove block and the second inclined fixing block is beneficial to improving the firmness of the crimping between the male terminal and the female terminal, ensuring the stable conduction use between the male terminal and the female terminal, and thus ensuring the crimping quality of the coupler terminal.

[0022] 3. In the present invention, when the second inclined fixing block rises, it will contact and push the limiting rod to slide upward on the female terminal. When the limiting rod separates from the limiting inclined block, under the action of the third spring, the limiting inclined block is pushed to move rightward. At this time, the right inclined surface of the limiting inclined block will move to the lower left side of the left end of the second inclined fixing block. When the second inclined fixing block slides downward and resets under the action of the second spring, the elastic force of the second spring is greater than that of the third spring. So the second inclined fixing block will squeeze and cross the right inclined surface of the limiting inclined block (the limiting inclined block will slide leftward, compressing the third spring). When the second inclined fixing block is reset and inserted onto the fixed groove block, the upper end of the second inclined fixing block will be lower than the lower end of the limiting inclined block. At this time, the limiting inclined block will reset rightward under the action of the third spring, and the lower end of the limiting inclined block is located above the second inclined fixing block, which is beneficial to preventing the second inclined fixing block from disengaging from the fixed groove block under the action of accidental collision, thus ensuring that the second inclined fixing block can be stably inserted into the fixed groove block, ensuring the stability after crimping between the female terminal and the male terminal, ensuring the crimping quality of the female terminal and the male terminal, and being flexible and self - detachable with strong applicability.

[0023] 4. In the present invention, when the movable frame moves to the left, it will also drive the top bar to move to the left synchronously. The top bar will contact the pressure plate and squeeze the pressure plate to drive the second connecting rod to slide to the left, compressing the fourth spring and the airbag. The gas is ejected from the nozzle tube, facilitating the ejection of dust and debris in the female terminal slot to the outside through the through groove, ensuring that the subsequent male terminal and the female terminal can smoothly contact and conduct electricity, and improving the crimping quality between the coupler terminals.

[0024] 5. In the present invention, when the limiting inclined block moves to the right, it will also drive the protective plates on both sides to move to the right synchronously, facilitating the blocking of the through grooves on both sides, preventing dust and humid air from the outside from entering through the through grooves during subsequent use, resulting in rusting of the conducting head, poor wire contact, or short circuit.

[0025] 6. In the present invention, when the movable frame moves to the left, the telescopic rods provided on both sides will adaptively contract. The telescopic rods ensure that the movable frame can slide stably horizontally, preventing the male terminal from being unable to be inserted into the female terminal normally and smoothly due to misalignment of the angle of the movable frame, and preventing the male terminal from being inclined, resulting in excessive wear during the insertion process and affecting the crimping quality between the terminals.

[0026] 7. In the present invention, when the telescopic rods adaptively contract, they will also drive the cleaning ring, the fixed ring, and the support block to move synchronously. The cleaning ring provided facilitates the cleaning of debris and dust adhering to the outer surface of the telescopic rod of the telescopic rod, preventing debris and dust from affecting the normal telescoping of the telescopic rod and preventing the telescopic rod from telescoping smoothly, thus affecting the subsequent terminal crimping quality.

[0027] 8. In the present invention, when the fixed ring moves to the left, it will also drive the first magnet to move synchronously. When the first magnet approaches the side of the second magnet, it will be subjected to magnetic repulsion, pushing the first magnet to move in the direction of approaching each other, thereby driving the fixed ring and the cleaning ring to slide on the support block, compressing the fifth spring. The fifth spring provided plays a reset role, so that when the cleaning ring slides on the telescopic rod, it will also rotate reciprocally, improving the cleaning quality of debris and dust on the surface of the telescopic rod, and thus improving the subsequent terminal crimping quality.

[0040] Refer to Figures 1-7, a coupler terminal crimping device, including a frame 1. On the left side of the upper end of the frame 1, a fixed frame 2 is fixedly installed. On the right side of the fixed frame 2 at the upper end of the frame 1, a movable frame 3 is slidably installed. At the upper end of the fixed frame 2, a female terminal 201 is clamped. At the upper end of the movable frame 3, a male terminal 301 is clamped. At the right end of the movable frame 3, an electric push rod 4 is fixedly installed, and the right end of the electric push rod 4 is fixedly installed on the frame 1. There is also a crimping mechanism for crimping the female terminal 201 and the male terminal 301. The crimping mechanism includes a first inclined fixed block 5 movably inserted at the front ends of the female terminal 201 and the male terminal 301. At the front end of the first inclined fixed block 5, a first connecting rod 6 is fixedly installed. The front ends of the two first connecting rods 6 on both sides respectively penetrate and are slidably installed on the fixed frame 2 and the movable frame 3, and a first spring 7 is sleeved on the outer side of the first connecting rod 6. At the front and rear of the left end of the male terminal 301, fixed groove blocks 8 are symmetrically fixedly installed, and at the front and rear ends of the female terminal 201, second inclined fixed blocks 9 corresponding to the fixed groove blocks 8 are slidably installed. At the upper ends of the second inclined fixed blocks 9, second springs 10 are fixedly installed, and the upper ends of the second springs 10 are fixedly installed on the female terminal 201. At the front and rear ends of the female terminal 201, limiting inclined blocks 11 corresponding to the second inclined fixed blocks 9 are slidably installed. At the left ends of the limiting inclined blocks 11, third springs 12 are fixedly installed, and the left ends of the third springs 12 are fixedly installed on the female terminal 201. At the upper ends of the limiting inclined blocks 11, limiting rods 13 are inserted, and the ends of the limiting rods 13 close to each other are slidably connected to the female terminal 201. At the right end of the female terminal 201, a slot is provided corresponding to the male terminal 301. At the front and rear of the right side of the female terminal 201, through slots 14 are symmetrically opened corresponding to the slot, and at the lower ends of the limiting inclined blocks 11 corresponding to the through slots 14, protective plates 15 are fixedly installed. At the front side of the female terminal 201 corresponding to the through slots 14, a nozzle pipe 16 is provided. At the upper end of the nozzle pipe 16, an airbag 17 is communicated. The left end of the airbag 17 is fixedly connected to the fixed frame 2. At the right end of the airbag 17, a pressing plate 18 is fixedly installed, and at the left end of the movable frame 3, a top bar 181 corresponding to the pressing plate 18 is fixedly installed. At the front and rear of the left end of the pressing plate 18, second connecting rods 19 are fixedly installed. The left ends of the second connecting rods 19 penetrate and are slidably installed on the fixed frame 2, and a fourth spring 20 is sleeved on the outer side of the second connecting rod 19;

[0041] During operation, the female terminal 201 and the male terminal 301 are respectively pressed onto the fixed frame 2 and the movable frame 3 from the upper ends of the fixed frame 2 and the movable frame 3. Since the inclined surface at the upper end of the first inclined fixing block 5 is subjected to the extrusion forces of the female terminal 201 and the male terminal 301, it will drive the first connecting rod 6 to slide forward, compressing the first spring 7. Until the lower ends of the female terminal 201 and the male terminal 301 respectively fit against the inner bottom ends of the fixed frame 2 and the movable frame 3, the first inclined fixing block 5 and the first connecting rod 6 will slide backward and reset under the action of the first spring 7, so that the first inclined fixing block 5 is respectively inserted onto the female terminal 201 and the male terminal 301, facilitating the automatic fixation of the female terminal 201 and the male terminal 301, improving the crimping efficiency, and automatically aligning and adjusting the crimping horizontal angle of the female terminal 201 and the male terminal 301 to ensure the subsequent crimping quality. Start the electric push rod 4 to drive the movable frame 3 to slide towards the fixed frame 2. The movable frame 3 will drive the male terminal 301 to approach the female terminal 201 synchronously until the conductive head of the male terminal 301 is successfully inserted into the slot of the female terminal 201. At the same time, the male terminal 301 will also drive the fixed groove blocks 8 on both sides to move leftward synchronously. The fixed groove blocks 8 will gradually contact the inclined surface of the second inclined fixing block 9 and extrude the inclined surface of the second inclined fixing block 9, pushing the second inclined fixing block 9 to slide upward on the female terminal 201, compressing the second spring 10. Until the fixing groove at the upper end of the fixed groove block 8 passes over the lower end of the second inclined fixing block 9, under the action of the second spring 10, it pushes the second inclined fixing block 9 to slide downward and snap onto the fixed groove block 8. At this time, the male terminal 301 is also exactly fully inserted onto the female terminal 201. The electric push rod 4 stops pushing the movable frame 3 continuously, completing the crimping work between the male terminal 301 and the female terminal 201. The cooperation between the set fixed groove blocks 8 and the second inclined fixing block 9 is beneficial to improving the crimping firmness between the male terminal 301 and the female terminal 201, ensuring the stable conduction between the male terminal 301 and the female terminal 201, and thus guaranteeing the crimping quality of the coupler terminals. When the second inclined fixing block 9 rises, it will contact and push the limit rod 13 to slide upward on the female terminal 201. When the limit rod 13 separates from the limit inclined block 11, under the action of the third spring 12, it pushes the limit inclined block 11 to move rightward. At this time, the right end inclined surface of the limit inclined block 11 will move to the lower left side of the left end of the second inclined fixing block 9. When the second inclined fixing block 9 slides downward and resets under the action of the second spring 10, the elastic force of the second spring 10 is greater than that of the third spring 12, so the second inclined fixing block 9 will squeeze and cross over the right end inclined surface of the limit inclined block 11 (the limit inclined block 11 will slide leftward, compressing the third spring 12). When the second inclined fixing block 9 is reset and inserted onto the fixed groove block 8, the upper end of the second inclined fixing block 9 will be lower than the lower end of the limit inclined block 11. At this time, the limit inclined block 11 will reset rightward under the action of the third spring 12, and the lower end of the limit inclined block 11 is located above the second inclined fixing block 9, which is beneficial to preventing the second inclined fixing block 9 from disengaging from the fixed groove block 8 under accidental contact, thus ensuring that the second inclined fixing block 9 can be stably inserted into the fixed groove block 8.Thus, the stability after crimping between the female terminal 201 and the male terminal 301 is ensured, and the crimping quality between the female terminal 201 and the male terminal 301 is guaranteed. When the movable frame 3 moves leftward, the top bar 181 will also be driven to move leftward synchronously. The top bar 181 will contact the pressing plate 18 and squeeze the pressing plate 18 to drive the second connecting rod 19 to slide leftward, compressing the fourth spring 20 and the airbag 17. The gas is ejected from the nozzle tube 16, facilitating the ejection of dust and debris in the slot of the female terminal 201 to the outside through the through groove 14, ensuring that the subsequent male terminal 301 and the female terminal 201 can smoothly contact and conduct electricity, and improving the crimping quality between the coupler terminals. When the limiting inclined block 11 moves rightward, the protective plates 15 on both sides will also be driven to move rightward synchronously, facilitating the blocking of the through grooves 14 on both sides to prevent dust and humid air from entering through the through grooves 14 during subsequent use, resulting in rusting of the conducting head, poor wire contact, or short circuit.

[0042] As an embodiment of the present invention, a stabilizing mechanism for the stable crimping of the female terminal 201 and the male terminal 301 is further provided. The stabilizing mechanism includes telescopic rods 21 symmetrically and fixedly installed between the fixed frame 2 and the movable frame 3 before and after. A cleaning ring 22 is provided in a fitting and abutting manner at the middle connection of the telescopic rods 21. Fixed rings 23 are fixedly installed on the outer sides of the cleaning ring 22. Support blocks 24 are slidably installed on the outer sides of the fixed rings 23. The support blocks 24 are fixedly connected to the outer tube of the telescopic rod 21. Upper ends of the support blocks 24 are fixedly installed with fifth springs 25, and the upper ends of the fifth springs 25 are fixedly connected to the fixed rings 23. First magnetic blocks 26 are fixedly installed on the lower sides of the left ends of the fixed rings 23, and no less than five second magnetic blocks 27 are fixedly installed at equal intervals on the upper end of the frame 1 on the sides where the first magnetic blocks 26 are away from each other;

[0043] During operation, when the movable frame 3 moves to the left, the telescopic rods 21 arranged on both sides will contract adaptively. The arranged telescopic rods 21 ensure that the movable frame 3 can slide stably horizontally, avoiding the situation that the tapping terminal 301 cannot be inserted into the female terminal 201 smoothly due to the misalignment of the angle of the movable frame 3, and the tapping terminal 301 is inclined, resulting in large wear during the insertion process and affecting the crimping quality between the terminals. When the telescopic rods 21 contract adaptively, they will also drive the cleaning ring 22, the fixing ring 23 and the support block 24 to move synchronously. The arranged cleaning ring 22 is convenient for cleaning the debris and dust adhering to the outer surface of the telescopic rods 21 of the telescopic rods 21, avoiding the influence of debris and dust on the normal expansion and contraction of the telescopic rods 21 and the situation of unsmooth expansion and contraction when the telescopic rods 21 expand and contract, thus affecting the subsequent terminal crimping quality. When the fixing ring 23 moves to the left, it will also drive the first magnet 26 to move synchronously. When the first magnet 26 approaches the side of the second magnet 27, it will be subjected to magnetic repulsion, pushing the first magnet 26 to move in the direction of approaching each other, and then driving the fixing ring 23 and the cleaning ring 22 to slide on the support block 24, compressing the fifth spring 25. The arranged fifth spring 25 plays a role in resetting, so that when the cleaning ring 22 slides on the telescopic rod, it will also rotate reciprocally, improving the cleaning quality of the debris and dust on the surface of the telescopic rod, and further improving the subsequent terminal crimping quality.

[0044] Working principle:

[0045] When the present invention is in use, the female terminal 201 and the male terminal 301 are respectively pressed on the fixed frame 2 and the movable frame 3 from the upper ends of the fixed frame 2 and the movable frame 3. Since the inclined surface at the upper end of the first inclined fixing block 5 is subjected to the extrusion force of the female terminal 201 and the male terminal 301, it will drive the first connecting rod 6 to slide forward, compress the first spring 7. Until the lower ends of the female terminal 201 and the male terminal 301 are respectively in contact with the inner bottom ends of the fixed frame 2 and the movable frame 3, the first inclined fixing block 5 and the first connecting rod 6 will slide backward and reset under the action of the first spring 7, so that the first inclined fixing block 5 is respectively inserted on the female terminal 201 and the male terminal 301, which is convenient for automatically fixing the female terminal 201 and the male terminal 301, improving the crimping efficiency, and automatically aligning and adjusting the crimping horizontal angle of the female terminal 201 and the male terminal 301 to ensure the subsequent crimping quality. Start the electric push rod 4 to drive the movable frame 3 to slide towards the fixed frame 2. The movable frame 3 will drive the male terminal 301 to approach the female terminal 201 synchronously until the conductive head of the male terminal 301 is successfully inserted into the slot of the female terminal 201. At the same time, the male terminal 301 will also drive the fixed groove blocks 8 on both sides to move leftward synchronously. The fixed groove blocks 8 will gradually contact the inclined surface of the second inclined fixing block 9 and extrude the inclined surface of the second inclined fixing block 9, pushing the second inclined fixing block 9 to slide upward on the female terminal 201, compressing the second spring 10. Until the fixing groove at the upper end of the fixed groove block 8 crosses the lower end of the second inclined fixing block 9, under the action of the second spring 10, it pushes the second inclined fixing block 9 to slide downward and snap onto the fixed groove block 8. At this time, the male terminal 301 is also exactly completely inserted on the female terminal 201. The electric push rod 4 stops pushing the movable frame 3 continuously, and the crimping work between the male terminal 301 and the female terminal 201 is completed. The cooperation between the set fixed groove block 8 and the second inclined fixing block 9 is beneficial to improving the crimping firmness between the male terminal 301 and the female terminal 201, ensuring the stable conduction use between the male terminal 301 and the female terminal 201, thereby ensuring the crimping quality of the coupler terminal. When the second inclined fixing block 9 rises, it will contact and push the limiting rod 13 to slide upward on the female terminal 201. When the limiting rod 13 is separated from the limiting inclined block 11, under the action of the third spring 12, it pushes the limiting inclined block 11 to move rightward. At this time, the right inclined surface of the limiting inclined block 11 will move to the lower left side of the left end of the second inclined fixing block 9. When the second inclined fixing block 9 slides downward and resets under the action of the second spring 10, the elastic force of the second spring 10 is greater than that of the third spring 12, so the second inclined fixing block 9 will squeeze and cross the right inclined surface of the limiting inclined block 11 (the limiting inclined block 11 will slide leftward, compressing the third spring 12). When the second inclined fixing block 9 is reset and inserted into the fixed groove block 8, the upper end of the second inclined fixing block 9 will be lower than the lower end of the limiting inclined block 11. At this time, the limiting inclined block 11 will reset rightward under the action of the third spring 12, and the lower end of the limiting inclined block 11 is located on the upper side of the second inclined fixing block 9, which is beneficial to preventing the second inclined fixing block 9 from disengaging from the fixed groove block 8 under the action of accidental collision, thereby ensuring that the second inclined fixing block 9 can be stably inserted into the fixed groove block 8.Thus, the stability after crimping between the female terminal 201 and the male terminal 301 is ensured, and the crimping quality between the female terminal 201 and the male terminal 301 is guaranteed. When the movable frame 3 moves leftward, it will also drive the top bar 181 to move leftward synchronously. The top bar 181 will contact the pressing plate 18 and squeeze the pressing plate 18 to drive the second connecting rod 19 to slide leftward, compressing the fourth spring 20 and the airbag 17. The gas is ejected from the nozzle tube 16, facilitating the ejection of dust and debris in the slot of the female terminal 201 to the outside through the through slot 14, ensuring that the subsequent male terminal 301 and the female terminal 201 can smoothly contact and conduct electricity, and improving the crimping quality between the coupler terminals. When the limiting inclined block 11 moves rightward, it will also drive the protective plates 15 on both sides to move rightward synchronously, facilitating the blocking of the through slots 14 on both sides to prevent dust and humid air from entering through the through slots 14 during subsequent use, resulting in rusting of the conducting head, poor wire contact, or short circuit. When the movable frame 3 moves leftward, the telescopic rods 21 provided on both sides will adaptively contract. The provided telescopic rods 21 ensure that the movable frame 3 can slide stably horizontally, preventing the male terminal 301 from being unable to be inserted into the female terminal 201 normally and smoothly due to the misalignment of the angle of the movable frame 3, and preventing the male terminal 301 from being inclined, resulting in excessive wear during the insertion process and affecting the crimping quality between the terminals. When the telescopic rods 21 adaptively contract, they will also drive the cleaning ring 22, the fixing ring 23, and the support block 24 to move synchronously. The provided cleaning ring 22 facilitates the cleaning of debris and dust adhering to the outer surface of the telescopic rod of the telescopic rod 21, preventing the debris and dust from affecting the normal telescoping of the telescopic rod 21 and the situation of unsmooth telescoping when the telescopic rod 21 telescopes, thereby affecting the subsequent terminal crimping quality. When the fixing ring 23 moves leftward, it will also drive the first magnet 26 to move synchronously. When the first magnet 26 approaches the side of the second magnet 27, it will be subjected to magnetic repulsion and be pushed to move in the direction of approaching each other, thereby driving the fixing ring 23 and the cleaning ring 22 to slide on the support block 24 and compressing the fifth spring 25. The provided fifth spring 25 plays a reset role, enabling the cleaning ring 22 to rotate reciprocally when sliding on the telescopic rod, improving the cleaning quality of debris and dust on the surface of the telescopic rod, and thus improving the subsequent terminal crimping quality.
