[0035] In this way, the arc block 702 and the rubber column 703 are placed in the through hole 701, and then the first dovetail block 5 on the adjacent fixed block 2 is inserted into the first dovetail groove 6. At this time, the rounded corner 704 on the right side of the fixed block 2 squeezes the arc block 702, and the arc block 702 drives the rubber column 703 to deform and press against the pin 4 for preliminary fixation.
[0036] like Figure 2 and Figure 7As shown, in this embodiment, a rounded corner 704 corresponding to the arc block 702 is formed at the right end of the rear side of the fixing block 2 , and the diameter of the rubber column 703 is smaller than the diameter of the through hole 701 .
[0037] Such a configuration is beneficial to the deformation of the rubber column 703 , and the restoring force of the rubber column 703 can better press against the pin 4 .
[0038] like Figure 6 and Figure 8 As shown, in this embodiment, the positioning assembly 8 includes a second dovetail groove 801 opened on the upper and lower sides of the fixed block 2, and the second dovetail groove 801 is slidably connected to the inside of the second dovetail groove 801. A cavity 803 is opened on the upper and lower sides of the fixed block 2 and located at the second dovetail groove 801. A movable block 804 is slidably connected to the inside of the cavity 803. A push rod 805 is fixedly connected to one side of the movable block 804. One end of the push rod 805 is located in the second dovetail groove 801 and fixedly connected to the push block 806. An arc groove 807 corresponding to the push block 806 is opened on the second dovetail block 802. A push pin 808 is fixedly connected to the other side of the movable block 804. The other end of the push pin 808 corresponds to the pin 4. The outer surface of the push rod 805 located in the cavity 803 is sleeved with a first spring 809.
[0039] This arrangement pushes the second dovetail block 802 to move to the right. At this time, the top block 806 is squeezed to drive the top rod 805 and the movable block 804 to move. During the movement of the movable block 804, the top pin 808 presses against the pin 4, thereby completely fixing the pin 4 and the fixed block 2.
[0040] like Figure 1 and Figure 3 As shown, in this embodiment, a female end plug 9 is also included, on which a socket 10 corresponding to the pin 4 is provided, and guide columns 11 are fixedly connected to the front and rear sides of the injection molded bracket 1, and guide grooves 12 corresponding to the guide columns 11 are provided on the front and rear sides of the female end plug 9. The length of the guide column 11 is greater than the length of the right end of the pin 4, and the number of the front and rear guide columns 11 is different.
[0041] In this way, the guide column 11 is inserted into the guide groove 12, and then the pin 4 is inserted into the socket 10 on the female plug 9. Since the number of the front and rear guide columns 11 is different, the reverse insertion is avoided.
[0042] like Figure 1 and Figure 2As shown, in this embodiment, two fixing seats 13 are fixedly connected to the upper surface of the injection molding bracket 1, a pin shaft 14 is rotatably connected between the two fixing seats 13, a first movable plate 15 is rotatably connected between the two fixing seats 13 through the pin shaft 14, a torsion spring 16 is installed on the outer surface of the pin shaft 14 and between the first movable plate 15 and the fixing seat 13, a buckle 17 is fixedly connected to the right side of the first movable plate 15, a second movable plate 18 is arranged on the upper surface of the female end plug 9, and a slot 19 corresponding to the buckle 17 is opened on the upper surface of the second movable plate 18.
[0043] In this way, the left hand presses the first movable plate 15 to rotate it around the pin shaft 14 and compress the torsion spring 16, and then the guide column 11 is inserted into the guide groove 12, and then the pin 4 is inserted into the socket 10 on the female plug 9. After the first movable plate 15 is inserted into the position, the first movable plate 15 is released. At this time, the restoring force of the torsion spring 16 resets the first movable plate 15 and engages the buckle 17 with the slot 19, which is very convenient to use.
[0044] like Figure 3 and Figure 4 As shown, in this embodiment, the buckle 17 is in a barb-shaped structure, a reset component 20 is provided on the female plug 9, and the second movable plate 18 is arranged on the upper surface of the female plug 9 through the reset component 20.
[0045] In this way, the buckle 17 and the slot 19 are connected together, which makes the fixation more firm and prevents the movable plate on the operating side from falling off.
[0046] like Figure 2 and Figure 4 As shown, in this embodiment, the reset assembly 20 includes a groove 201 opened on the upper surface of the female plug 9, a movable seat 202 is fixedly connected to the lower surface of the second movable plate 18, two slide bars 203 are fixedly connected to the left inner wall of the groove 201, the right end of the slide bar 203 passes through the movable seat 202 and is fixedly connected to the right inner wall of the groove 201, the slide bar 203 is slidably connected to the movable seat 202, and the outer specific surface of the slide bar 203 is sleeved with a second spring 204.
[0047] In this way, the right hand presses the second movable plate 18 and moves it to the left along the slide bar 203 and compresses the second spring 204, then the guide column 11 is inserted into the guide groove 12, and then the pin 4 is inserted into the socket 10 on the female plug 9. After the second movable plate 18 is inserted into position, the restoring force of the second spring 204 makes the buckle 17 and the slot 19 snap together to prevent them from falling off.
[0048] like Figure 1 and Figure 3 As shown, in this embodiment, the upper surfaces of the first movable plate 15 and the second movable plate 18 are both provided with anti-slip grooves.
[0049] The friction between the booster hand and the first movable plate 15 and the second movable plate 18 is set in this way to avoid the hand slipping phenomenon.
[0050] The technical solution provided by the present invention is that when in use, the pin 4 is inserted into the mounting hole 3 on the fixed block 2, and then the arc block 702 and the rubber column 703 are placed in the through hole 701, and then the first dovetail block 5 on the adjacent fixed block 2 is inserted into the first dovetail groove 6. At this time, the fillet 704 on the right side of the fixed block 2 squeezes the arc block 702, and the arc block 702 drives the rubber column 703 to deform and press the pin 4 to perform preliminary fixation. In the above manner, the fixed block 2 and the pin 4 are spliced together until the required specifications are formed, and then the pin 4 is slightly moved to make the right sides of multiple pins 4 flush, and then the second dovetail block 802 is pushed to move to the right. At this time, the top block 806 is squeezed to drive the top rod 805 and the movable block 804 to move. During the movement of the movable block 804, the top pin 808 presses the pin 4, so that the pin 4 and the fixed block 2 are completely fixed, and then the injection molded bracket 1 and the guide column 11 are formed by injection molding;
[0051] When connecting with the female end plug 9, first press the first movable plate 15 with the left hand to rotate it around the pin shaft 14 and compress the torsion spring 16, press the second movable plate 18 with the right hand and make it move to the left along the slide bar 203 and compress the second spring 204, then insert the guide column 11 into the guide groove 12, and then insert the pin 4 into the socket 10 on the female end plug 9. After inserting it into the position, release the first movable plate 15. At this time, the restoring force of the torsion spring 16 resets the first movable plate 15 and makes the position of the buckle 17 correspond to the position of the slot 19. Then release the second movable plate 18. At this time, the restoring force of the second spring 204 makes the buckle 17 and the slot 19 snap together, so that the pin 4 and the female end plug 9 are firmly connected together.
