[0022] According to the present specific embodiment, the two slots 111 are inserted into the corresponding grooves 110, so that the first pressing plate 103 and the second pressing plate 104 are connected, and then the first bolt 105 cooperates with the first threaded hole 113, and the second bolt 106 cooperates with the second threaded hole 114, so that the first pressing plate 103 and the second pressing plate 104 are fixed to the base 101, and the two pressing ends 109 are used to press the injector body 102. Thus, through the above-mentioned structural setting, the injector body 102 can be pressed, and the pressing effect is good, and it will not loosen after long-term use. 5, so that when the staff removes the first pressing plate 103 and the second pressing plate 104, it can prevent the hand from slipping and improve the friction. When the first pressing plate 103 and the second pressing plate 104 cancel the clamping state of the injector body 102, the setting of the lifting rod 107 makes it convenient for the staff to remove the injector body 102. When the injector body 102 is installed in the installation hole 112, the cooperation of the positioning rod 108 and the positioning hole enables the staff to quickly and correctly install the injector body 102, so as to facilitate the subsequent clamping and fixing of the injector body by the first pressing plate 103 and the second pressing plate 104.
[0023] Among them, the right side of the first pressing plate 103 has two clamping ends 109, and the two clamping ends 109 respectively have grooves 110, the left side of the second pressing plate 104 has two slots 111, the base 101 has a mounting hole 112, and the base 101 has a first threaded hole 113 and a second threaded hole 114 respectively, the bottom of the injector body 102 passes through the mounting hole 112, the first threaded hole 113 and the second threaded hole 114 are symmetrically arranged on both sides of the mounting hole 112, the two clamping ends 109 of the first pressing plate 103 are arranged on both sides of the injector body 102, and the two slots 111 are respectively inserted into the corresponding grooves 110, the first bolt 105 passes through the first pressing plate 103 and is threadedly adapted to the first threaded hole 113, and the second bolt 106 passes through the second pressing plate 104 and is threadedly adapted to the second threaded hole 114. The first pressing plate 103 and the second pressing plate 104 are connected by inserting the two slots 111 into the corresponding grooves 110, and then the first pressing plate 103 and the second pressing plate 104 are fixed to the base 101 by the cooperation of the first bolt 105 and the first threaded hole 113, and the second bolt 106 and the second threaded hole 114, and the injector body 102 is pressed by the two pressing ends 109. Thus, the injector body 102 can be pressed by the above-mentioned structural setting, and the pressing effect is good, and it will not loosen after long-term use.
[0024] Secondly, the first pressing plate 103 and the second pressing plate 104 are provided with pressing lines 115. The setting of the pressing lines 115 prevents the staff from slipping when removing the first pressing plate 103 and the second pressing plate 104, thereby improving the friction.
[0025] At the same time, the lifting rod 107 is fixedly connected to the injector body 102 and is located on the left side of the injector body 102. When the first pressing plate 103 and the second pressing plate 104 cancel the pressing state of the injector body 102, the setting of the lifting rod 107 makes it convenient for the staff to take and disassemble the injector body 102.
[0026] In addition, the base 101 has a positioning groove 116, the positioning rod 108 is fixedly connected to the injector body 102 and is located at the front end of the injector body 102, and the bottom of the positioning rod 108 is adapted to the positioning groove 116. When the injector body 102 is installed in the mounting hole 112, the positioning rod 108 cooperates with the positioning hole, so that the staff can quickly and correctly install the injector body 102, thereby facilitating the subsequent pressing and fixing of the injector body 102 by the first pressing plate 103 and the second pressing plate 104.
[0027] When using the fuel injector pressure plate support mechanism of the present embodiment, the two slots 111 are inserted into the corresponding grooves 110, so that the first pressure plate 103 and the second pressure plate 104 are connected, and then the first bolt 105 cooperates with the first threaded hole 113, and the second bolt 106 cooperates with the second threaded hole 114, so that the first pressure plate 103 and the second pressure plate 104 are fixed to the base 101, and the two clamping ends 109 are used to clamp the fuel injector body 102. Thus, through the above-mentioned structural setting, the fuel injector body 102 can be clamped, and the clamping effect is good, and it will not loosen after long-term use. The provision of the embossed pattern 115 prevents the staff from slipping when removing the first pressing plate 103 and the second pressing plate 104, thereby improving the friction. When the first pressing plate 103 and the second pressing plate 104 cancel the clamping state of the injector body 102, the provision of the lifting rod 107 facilitates the staff to remove the injector body 102. When the injector body 102 is installed in the installation hole 112, the cooperation between the positioning rod 108 and the positioning hole enables the staff to quickly and correctly install the injector body 102, thereby facilitating the subsequent clamping and fixing of the injector body 102 by the first pressing plate 103 and the second pressing plate 104.
