The foregoing scheme solves the problem that the existing cleaning operation needs to be completed by two people, resulting in low efficiency, and the oil basin is exposed and placed, which is easy to produce oil vapor and oil splashing to the ground, which is not conducive to the occupational health of the workers.

[0031] Further, four groups of the universal wheels 2 are installed at the bottom of the loading box 1, the push handle 3 is fixedly installed at the side of the loading box 1, the guide bracket 4 is fixedly installed at the side of the loading box 1, the clamping frame 5 is slidingly installed on the guide bracket 4, the clamping member 6 is installed on the clamping frame 5, and is used for clamping and limiting the placed oil filling head, and the lifting member 7 is installed on the guide bracket 4, and is used for adjusting the up-down position of the clamping frame 5.

[0032] Specifically, the bottom of the loading box 1 is provided with four universal wheels 2, and the push handle 3 is further fixed at the side of the loading box 1, so as to facilitate the user to collect oil through the loading box 1, and then move the loading box 1 through the push handle 3 cooperating with the universal wheels 2. The side of the loading box 1 is fixed with the fixed bracket, the clamping frame 5 is slidingly installed on the fixed bracket, the clamping frame 5 can slide on the guide bracket 4 through the lifting member 7, so as to change the clamping height, so that the user can adjust the clamping height according to the actual size of the oil filling head, and then clamp and limit the oil filling head through the clamping member 6 provided on the clamping frame 5, so as to ensure that the oil filling head does not need to be manually supported during oil discharge. After the oil filling head finishes discharging oil, it can be disassembled and cleaned. The whole oil discharging and cleaning process does not need to be operated with the assistance of multiple people, and a single person can clean the oil filling head.

[0033] Further, two groups of the guide rods 601 are respectively fixedly installed on the two sides of the clamping frame 5, each group of the guide rods 601 is provided with two; two clamping frames 602 are respectively connected with two groups of the guide rods 601; two groups of the single driving components 603 are respectively connected with two clamping frames 602 in a corresponding manner, and are used for driving the corresponding clamping frame 602 to move; the linkage component 604 is connected with the clamping frame 602, and is used for synchronously controlling two groups of the single driving components 603; two groups of the locking components 605 are respectively connected with two clamping frames 602, and are used for limiting the top of the oil filling head clamped by the clamping frame 5.

[0034] Further, the moving block 6031 is slidingly installed on the clamping frame 5; the pushing piece 6032 is rotationally connected with the moving block 6031 and is rotationally installed on the clamping frame 602; and the pushing screw 6033 is threadedly connected with the moving block 6031 and is rotationally installed on the clamping frame 5.

[0035] Further, the bottom of each pushing screw rod 6033 is fixed with a driving bevel gear 6041; the rotating member 6043 is rotatably installed on the clamping frame 5; each driving bevel gear 6041 cooperates with a corresponding driving bevel gear 6042, and all the driving bevel gears 6042 are fixedly sleeved on the rotating member 6043.

[0036] Further, the sliding lock block 6051 is slidingly installed on the top of the clamping frame 602; and the two sides of the ejection spring 6052 are respectively connected with the sliding lock block 6051 and the clamping frame 5.

[0037] In use, the two clamping frames 602 cooperate with the guide rods 601 arranged on the two sides of the clamping frame 5, so that the two clamping frames 602 can slide on the side of the clamping frame 5. Each clamping frame 602 is driven by the two groups of moving blocks 6031 and the pushing member 6032 cooperating with the pushing screw rod 6033. The threads on the two sides of the pushing screw rod 6033 are oppositely arranged. When the pushing screw rod 6033 rotates, the moving blocks 6031 cooperating with the threads on the two sides of the pushing screw rod 6033 will expand or approach each other under the driving of the pushing screw rod 6033, and then drive the clamping frame 602 on the corresponding side to slide by cooperating with the pushing member 6032.

[0038] The bottom of the two push screws 6033 is fixed with the driving bevel gear 6041, and the two driving bevel gears 6041 are engaged with the two driving bevel gears 6042 arranged on the rotating member 6043, respectively. 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, thereby driving the two driving bevel gears 6042 arranged to rotate. In order to ensure the consistency of the clamping of the two clamping frames 602, the user needs to adjust the actual engagement type of the driving bevel gear 6041 and the driving bevel gear 6042 according to the actual thread condition of the two push screws 6033 selected, so 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 two push screws 6033 on both sides to rotate. When the two push screws 6033 rotate, the moving block 6031 can cooperate with the pusher 6032 to complete the driving of the corresponding clamping frame 602. When driving the two clamping frames 602, it should be noted that when driving synchronously, the two groups of moving blocks 6031 need to be expanded and folded synchronously, so as to drive the two clamping frames 602 synchronously. The synchronous expansion and folding of the two groups of moving blocks 6031 is driven by the two push screws 6033 on both sides, and the driving direction of the two push screws 6033 on both sides depends on the thread and rotation direction arranged by itself. Therefore, the user needs to determine the actual engagement condition of the driving bevel gear 6041 and the driving bevel gear 6042 according to the specific thread type of the two push screws 6033 selected. The two push screws 6033 selected in the scheme belong to the same type, so the rotation direction of the two push screws 6033 needs to be ensured consistent when driving. In this way, it is only necessary to ensure that the direction of the two corresponding bevel gear sets remains consistent when transmitting.
