The above-mentioned solution solves the problem that the existing cleaning operation is inefficient because it requires two people to cooperate, and the oil pan is easily placed open to generate oil vapor and oil splashing to the ground, which is not conducive to the occupational health of the operators.

[0031] Furthermore, the four groups of universal wheels 2 are installed at the bottom of the loading box 1, the push handle 3 is fixedly installed on the side of the loading box 1, the guide bracket 4 is fixedly installed on the side of the loading box 1, the clamping frame 5 is slidably installed on the guide bracket 4, the clamping member 6 is installed on the clamping frame 5, and is used to clamp and limit the placed refueling head, and the lifting member 7 is installed on the guide bracket 4, and is used to adjust the upper and lower positions of the clamping frame 5.

[0032] Specifically, four universal wheels 2 are provided at the bottom of the loading box 1, and the push handle 3 is also fixed to the side of the loading box 1, so that the user can collect the oil through the loading box 1, and then drive the loading box 1 to move by the push handle 3 and the universal wheel 2. The fixed bracket is fixed to the side of the loading box 1, and the clamping frame 5 is slidably installed on the fixed bracket. The clamping frame 5 can slide on the guide bracket 4 through the lifting member 7, thereby changing the overall clamping height, so that the user can adjust the clamping height according to the actual size of the refueling head, and then the refueling head is clamped and limited by the clamping member 6 provided on the clamping frame 5, to ensure that the refueling head does not need to be manually supported and stabilized during the oil draining process, and can be disassembled for cleaning after the oil draining is completed. The entire oil draining and cleaning process does not require the assistance of multiple people to operate, and the refueling head can be cleaned by a single person.

[0033] Furthermore, the two groups of guide rods 601 are respectively fixedly installed on both sides of the clamping frame 5, and each group of guide rods 601 is provided with two; the two clamping frames 602 are respectively connected with the two groups of guide rods 601; the two groups of single drive components 603 are respectively connected with the two clamping frames 602, and are used to drive the corresponding clamping frames 602 to move; the linkage component 604 is connected with the clamping frame 602, and is used to synchronously control the two groups of single drive components 603; the two groups of locking components 605 are respectively connected with the two clamping frames 602, and are used to limit the top of the refueling head after being clamped by the clamping frame 5.

[0034] Furthermore, the moving block 6031 is slidably mounted on the clamping frame 5; the pushing member 6032 is rotationally connected to the moving block 6031 and rotationally mounted on the clamping frame 602; the pushing screw 6033 is threadedly connected to the moving block 6031 and is convertibly mounted on the clamping frame 5.

[0035] Furthermore, the driving bevel gear 6041 is fixed at the bottom of each pushing screw 6033; the rotating member 6043 is rotatably installed on the clamping frame 5; each driving bevel gear 6041 must cooperate with the corresponding driving bevel gear 6042, and all the driving bevel gears 6042 are fixedly mounted on the rotating member 6043.

[0036] Furthermore, the sliding locking block 6051 is slidably installed on the top of the clamping frame 602; both sides of the ejection spring 6052 are connected to the sliding locking block 6051 and the clamping frame 5 respectively.

[0037] When the present embodiment is in use, the two clamping frames 602 cooperate with the guide rods 601 arranged on both sides of the clamping frame 5, so that the two clamping frames 602 can slide correspondingly on the sides of the clamping frame 5, and each of the clamping frames 602 is driven by the two groups of moving blocks 6031 and the pushing member 6032 in cooperation with the pushing screw 6033. The threads on both sides of the pushing screw 6033 are arranged in opposite directions. When the pushing screw 6033 rotates, the moving blocks 6031 cooperating with the threads on both sides of the pushing screw 6033 will be driven by the pushing screw 6033 to expand toward both sides or move closer to each other, and then cooperate with the pushing member 6032 to drive the clamping frame 602 on the corresponding side to slide;

[0038] The bottom of the two pushing screws 6033 is fixed with the driving bevel gears 6041, and the two driving bevel gears 6041 are respectively meshed with the two driving bevel gears 6042 provided on the rotating member 6043. The rotating member 6043 is composed of a corresponding rotating shaft and a knob at the end, so that the user can twist the knob to drive the rotating member 6043 to rotate, and then drive the two driving bevel gears 6042 to rotate. In order to ensure the consistency of the clamping of the clamping frames 602 on both sides, the user needs to adjust the actual meshing type of the driving bevel gears 6041 and the driving bevel gears 6042 according to the thread conditions of the two pushing screws 6033 actually selected, so as to achieve that when the user twists the rotating member 6043 to rotate, the two driving bevel gears 6042 will synchronously drive the two driving bevel gears 6041 to rotate, thereby driving the pushing screws 6033 on both sides to rotate. , the moving block 6031 can cooperate with the pushing member 6032 to complete the driving of the corresponding clamping frame 602 to drive the two clamping frames 602. It should be noted that when performing synchronous driving, the two groups of the moving blocks 6031 need to be synchronously expanded and closed, so as to synchronously drive the clamping frames 602 on both sides, and the synchronous expansion and closing of the two groups of the moving blocks 6031 are driven by the pushing screws 6033 on both sides, and the driving direction of the pushing screws 6033 on both sides depends on the threads and rotation directions set by themselves. Therefore, the user needs to determine the actual meshing of the driving bevel gear 6041 and the driving bevel gear 6042 according to the specific thread types of the two pushing screws 6033 selected. The two pushing screws 6033 selected in this solution are of the same type. Therefore, when driving, it is necessary to ensure that the two pushing screws 6033 have the same direction of rotation. In this way, it is only necessary to ensure that the directions of the two corresponding bevel gear sets are consistent during transmission;

[0039] The sliding lock block 6051 is also slidably installed on the top of each clamping frame 602, and the ejection spring 6052 is installed in the sliding groove that cooperates with the sliding lock block 6051 and the top of the clamping frame 602.

A corresponding card platform is also provided inside the loading box 1 for installing and placing the filter bracket 9. The filter bracket 9 includes a filter plate and an inclined scraper and a corresponding lifting handle arranged around the filter plate. The filter bracket 9 can filter the incoming oil through the filter plate at the bottom, so that when the oil is discharged through the discharge joint 8, impurities mixed in the oil will be blocked by the filter plate of the filter bracket 9. The inclined scraper and the lifting handle provided on the filter bracket 9 can remove and clean the impurities and dirt attached to the inner wall of the loading box 1 when the user pulls the filter bracket 9 out of the loading box 1 for cleaning, making it more convenient to clean the loading box 1 later.
