Current-mode technology refers to the technology of designing, manufacturing processes, and applications of current-mode integrated circuits. The main characteristics of current-mode integrated circuits are large capacity, high speed, high precision, wide bandwidth, good linearity, and high efficiency. In recent years, current-mode technology has developed rapidly and has become an important foundation for analog integrated circuits. When testing a current analog output circuit, in order to test the circuit, a testing device for a current analog output circuit is required, which is convenient for testing.

[0003] The existing Chinese patent CN111308324A discloses an integrated circuit testing device on June 19, 2020, belonging to the technical field of integrated circuit testing.

When placing, through the anti-slip rubber columns at the lower end of the outer wrapping shell, anti-slip support can be achieved, effectively avoiding sliding during placement. When testing the current in the current analog output circuit, personnel connect the test wire source. The wire source connected to the current analog output circuit test body is effectively buckled by the moving cleaning buckle plate on the positioning sliding frame, thus avoiding the loosening and falling off of the connected wire source. The moving cleaning buckle plate can move left and right on the positioning sliding frame through the moving handle plate, so that the moving cleaning buckle plate can clean the screen at the front end of the current analog output circuit test body during movement, making it more convenient for personnel to view.

[0010] The present utility model is further configured such that the sliding convex plate rolls with the positioning sliding frame through the rolling beads.

[0011] By the above technical solutions: Since the sliding convex plate rolls with the positioning sliding frame through the rolling beads, rolling movement can be achieved, making it more convenient to move.

[0012] The present utility model is further configured such that the lifting handle includes a handle outer shell, connecting screws, and a soft rubber pad. A soft rubber pad is provided inside the lower end of the handle outer shell. Connecting screws are provided in the middle of both ends of the handle outer shell. The handle outer shell is connected to the positioning sliding frame through the connecting screws.

[0014] The present utility model is further configured such that the positioning sliding frame includes an outer baffle, an assembly screw, a U-shaped frame, and a positioning chute. The inner side of the U-shaped frame is provided with a positioning chute. The right end of the U-shaped frame is provided with an outer baffle. The U-shaped frame and the outer baffle are installed and connected by an assembly screw. The U-shaped frame is connected to the outer wrapping shell.

[0015] Through the above technical solutions: Due to the structure of the positioning sliding frame, it can be positioned and slid for use.

[0016] The present utility model is further configured such that the U-shaped frame is welded to the outer wrapping shell, and the connection parts are aligned.

[0017] Through the above technical solutions: Since the U-shaped frame is welded to the outer wrapping shell and the connection parts are aligned, it can be installed and fixed, and the alignment of the connection parts ensures that there will be no obstruction during use.

[0018] The present utility model is further configured such that the anti-slip rubber column includes a bottom anti-slip rubber pad, a support column, and a top convex column. The lower end of the top convex column is provided with a support column. The lower end of the support column is provided with a bottom anti-slip rubber pad. The top convex column is connected to the outer wrapping shell.

[0020] The present utility model is further configured such that the left and right ends of the movable handle plate are provided with anti-slip rubber.

[0021] Through the above technical solutions: Since the left and right ends of the movable handle plate are provided with anti-slip rubber, it can effectively prevent slipping when holding and moving.

[0022] The beneficial effects of the present utility model are as follows:

[0023] 1. By providing a movable cleaning buckle plate structure, it can be positioned, buckled, and cleaned by sliding on the positioning sliding frame. The moving panel of the movable cleaning buckle plate is sleeved on the positioning sliding frame through a sliding convex plate, so that the moving panel can be positioned and moved. When moving, the sliding convex plate can roll and move in the positioning sliding frame due to the rolling ball beads, making it more convenient to move. When the moving panel moves, the dust on the front screen of the current simulation output circuit test body can be cleaned through the cleaning cotton pad on the moving panel, making it more convenient for personnel to view. When it needs to be buckled, it moves to the buckle position. Thus, due to the area of the buckle sleeve cavity, for the test wire source outside the buckle, when buckling, the friction force is effectively increased through the buckle rubber pad, so that it can effectively prevent sliding and falling off during buckling.

[0024] 2. By setting up a positioning sliding frame structure, it can be positioned and moved for use. The U-shaped frame of the positioning sliding frame is welded to the outer wrapping shell, so that the U-shaped frame is convenient for installation and placement. Through the positioning sliding groove on the inner side of the U-shaped frame, the movable cleaning buckle plate can be positioned and slid. During the sliding of the movable cleaning buckle plate, due to the blocking of the outer baffle on the right end of the U-shaped frame, it can be prevented from sliding and falling. The U-shaped frame and the outer baffle are installed and connected by assembly screws, so that the outer baffle is convenient for disassembly, making it convenient to replace the movable cleaning buckle plate for cleaning.
