The rear end of the guide rod 13 passes through the inside of the fixed plate 12 in the base plate 1, and a spring 14 is sleeved on the outside of the guide rod 13.

[0026] The slide 2 is located on the top of the base plate 1 and is arranged to slide back and forth, and the pressure plate 7 is arranged to slide up and down through two lifting cylinders 8.

[0027] The inner side of the clamping seat 10 matches the outer side of the positioning seat 5, and the bottom of the clamping seat 10 is sleeved on the outer periphery of the screw rod 9 in a threaded connection.

[0028] The guide rod 13 passes through the interior of the fixed plate 12 on the top of the base plate 1 and is slidably arranged. The spring 14 is located between the slide seat 2 and the two fixed plates 12 in the base plate 1.

[0029] Specifically, the positioning seat 5 is used to place the refrigerator drawer handle. The refrigerator drawer handle is in the shape of an L-shaped long strip. The pressure plate 7 slides up and down through the telescopic rod in the two lifting cylinders 8, which is convenient for pressing and fixing the refrigerator drawer handle. The sliding position of the clamping seat 10 is adjusted by the screw 9, and the refrigerator drawer handles of different lengths can be limited. The slide 2 slides back and forth through the slide rod 6, which is convenient for taking and placing the refrigerator drawer handle. Under the action of the spring 14, the slide 2 automatically slides forward.

[0030] Example 2

[0031] See Figure 3 and Figure 4 , and on the basis of Example 1, it is further obtained that the adjustment mechanism 4 includes an adjustment seat 15, the adjustment seat 15 is fixedly mounted on the top rear end of the base plate 1, a first adjustment rod 16 is movably mounted inside the adjustment seat 15, and a first rocking plate 17 is mounted at both ends of the first adjustment rod 16, two sliders 18 are movably mounted on the periphery of the first adjustment rod 16 and located on the top of the adjustment seat 15, a lifting seat 19 is fixedly mounted on the top of the two sliders 18, a second adjustment rod 20 is movably mounted inside the lifting seat 19, a second rocking plate 21 is mounted on the top of the second adjustment rod 20, a lifting block 22 is connected to the periphery of the second adjustment rod 20, and a chassis 23 is fixedly mounted on the front of the lifting block 22.
