A rack 58 is fixedly connected to the outer surface of one side of the support frame 57, and a bracket 59 is fixedly connected to the top of the vertical rod 51. A gear 511 is provided on one side of the bracket 59, and the gear 511 is meshed with the rack 58. The rotating shaft of the gear 511 is rotatably connected to the inner wall of the bracket 59, and one end of the rotating shaft of the gear 511 is fixedly connected to a knob 512.

[0023] The locking rod 53 has two sides, which are symmetrically distributed on the left and right sides of the vertical rod 51, and the top ends of the two locking rods 53 are in contact with the bottom surface of the base 1;

[0024] The vertical rod 51 can be locked by the locking rod 53 to prevent the vertical rod 51 from moving upward. The vertical rod 51 is pulled downward and the locking rod 53 is moved to rotate and retract into the inner wall of the vertical rod 51. At this time, the vertical rod 51 can be moved upward and the locking teeth 54 can lock the rack 58. Chambers are provided on the left and right surfaces of the vertical rod 51. The two locking rods 53 are located in the chambers on the left and right sides of the vertical rod 51. When the two locking rods 53 are rotated to the vertical state, the left surface of the left locking rod 53 and the right surface of the right locking rod 53 are respectively in the same plane with the left and right surfaces of the vertical rod 51. When the two locking rods 53 are rotated in opposite directions by a certain angle, the bottom ends of the two locking rods 53 contact the bottom surfaces of the two chambers. At this time, the two locking rods 53 cannot rotate further.

[0025] The length direction of the chute 56 is parallel to the length direction of the rack 58, and the workbench 2 and the cylinder 4 are fixedly mounted on the top of the support frame 57;

[0026] By rotating the gear 511 , the rack 58 can be moved along the direction of the slide groove 56 , thereby adjusting the positions of the support frame 57 and the workbench 2 .

[0027] Among them, the auxiliary component 6 includes a clamping block 61, which is fixedly connected to one end of the push rod of the cylinder 4, and an outer surface of one side of the clamping block 61 is fixedly connected to an L-shaped rod 62, and an outer surface of one side of the L-shaped rod 62 is fixedly connected to a support plate 63 and an extension frame 64, and the inner wall of the extension frame 64 is slidably connected to a guide rod 65, and the bottom end of the guide rod 65 is fixedly connected to a pressure plate 66, and the top surface of the pressure plate 66 is fixedly connected to a spring 2 67, and the top of the spring 2 67 is fixedly connected to the bottom surface of the extension frame 64, and a round tube 68 is fixedly installed on the top surface of the support frame 57, and the inner wall of the round tube 68 is slidably connected to a push rod 69, and the outer wall of the push rod 69 is fixedly connected to a lifting platform 611.

[0028] The extension frame 64 and the support plate 63 are respectively located on the upper and lower sides of the lifting platform 611, and the bottom surface of the pressing plate 66 is in contact with the top surface of the lifting platform 611;

[0029] By extending the push rod by the cylinder 4, the clamping block 61 can be driven to fix the workpiece on the top of the workbench 2, and at the same time, the L-shaped rod 62 and the extension frame 64 can be driven down. At this time, under the thrust of the spring 2 67, the pressure plate 66 applies a downward force to the lifting platform 611 and the push rod 69, so that the bottom surface of the lifting platform 611 fits with the top surface of the circular tube 68. At this time, the four push rods 69 will not interfere with the workpiece on the top of the workbench 2.

[0030] Among them, the cylinder 4 and the auxiliary component 6, except for the lifting platform 611, each has four components, distributed at the four corners of the lifting platform 611, and the four push rods 69 all pass through the workbench 2;

[0031] When the cylinder 4 contracts the push rod, the clamping block 61, L-shaped rod 62, support plate 63, and extension frame 64 are driven to rise. At this time, the clamping block 61 and pressure plate 66 are away from the workpiece, and the support plate 63 gradually approaches the lifting platform 611, lifting the lifting platform 611 upward and driving the four push rods 69 to lift the workpiece.

[0032] The working process of this utility model is as follows:

[0033] First, pull the handle 52 downward. At this time, the two locking rods 53 rotate to the left and right under the influence of gravity until the bottom ends of the two locking rods 53 contact the bottom surfaces of the left and right chambers of the vertical rod 51. Release the handle 52. At this time, under the thrust of spring 1 55, the two locking rods 53 fit into the top surface of the base 1, locking the vertical rod 51. At this time, turn the knob 512 to allow the gear 511 to drive the rack 58 to move along the slide 56, adjust the orientation of the support frame 57 and the workbench 2, and finally pull the handle 52 to rotate the two locking rods 53 to a vertical state, and the vertical rod 51 is locked. The rod 51 moves upward. At this time, under the thrust of spring 1 55, the tooth 54 locks the rack 58. When fixing the workpiece, the cylinder 4 drives the clamping block 61 to move downward to fix the workpiece. At the same time, under the thrust of spring 2 67, the pressure plate 66 presses the lifting platform 611 on the top surface of the circular tube 68, so that the push rod 69 cannot interfere with the workpiece. After the workpiece test is completed, the cylinder 4 retracts the push rod to make the clamping block 61 and the pressure plate 66 move away from the lifting platform 611. Then the support plate 63 approaches the bottom of the lifting platform 611 and lifts the lifting platform 611, so that the four push rods 69 lift the workpiece.
