When the rubber head 108 needs to be installed, the rectangular block 501 is inserted into the rectangular hole 503. When the rectangular block 501 abuts against the first inclined surface 506, the multiple blocks 505 can be pushed to move outward along the installation hole 504. When the rectangular block 501 abuts against the sliding plate 507, the sliding plate 507 can be pushed to move upward. At the same time, the first spring 508 is compressed. When the slot 502 is aligned with the block 505, under the action of the first reset mechanism, the block 505 is inserted into the slot 502, and under the action of the first spring 508, the slot 502 abuts against the top of the block 505, so that the rectangular block 501 can be limited.

[0037] Each first reset mechanism includes two symmetrically arranged first connecting blocks 601 fixedly connected to the side wall of the block 505, and a first T-shaped guide rod 602 is inserted into the side wall of each first connecting block 601, one end of the first T-shaped guide rod 602 is fixed to the side wall of the mounting seat 14, and a second spring 603 is sleeved on the side wall of each first T-shaped guide rod 602, which guides and resets the movement of the block 505.

[0038] The second pushing mechanism includes a pushing block 701 fixedly connected to the top of each card block 505, and a second inclined surface 702 is arranged on the top of the pushing block 701. The side wall of the mounting seat 14 is connected with a pushing ring 703 through a guiding mechanism. When the rubber head 108 needs to be disassembled and replaced, the pushing ring 703 is pushed to move downward and abut against the second inclined surface 702. The pushing block 701 can drive the card block 505 to move outward along the mounting hole 504 and withdraw from the card slot 502. Then, the rubber head 108 can be removed.

[0039] The guiding mechanism includes a second connecting block 801 fixedly connected to the bottom of the push ring 703, and the bottom of the second connecting block 801 is fixedly connected to two symmetrically arranged second T-shaped guide rods 802, the side wall of the second T-shaped guide rod 802 is sleeved with a third connecting block 803, and the third connecting block 803 is fixed to the side wall of the mounting seat 14, which guides and resets the movement of the push ring 703.

[0040] The limiting mechanism includes a fixing ring 901 fixedly sleeved on the side wall of the hinge shaft 102, and the side wall of the fixing ring 901 is provided with two symmetrically arranged limiting grooves 902, the limiting grooves 902 include a third inclined surface 903, and the side wall of the base 101 is connected with a moving block 904 through a second reset mechanism, the top of the moving block 904 is fixedly connected with a limiting block 905, and the limiting block 905 includes a fourth inclined surface 906. When the automobile parts are clamped and fixed, the handle 103 is rotated to rotate counterclockwise along the hinge shaft 102, so that the pressure handle 105 is rotated to a horizontal state, and the bolt 107 is rotated to a vertical state. At the same time, when the hinge shaft 102 is rotated, the belt The movable fixing ring 901 rotates synchronously, and when the third inclined surface 903 and the fourth inclined surface 906 abut against each other, the limit block 905 can be pushed to move downward, and the limit block 905 is withdrawn from the limit groove 902 and slides on the side wall of the fixing ring 901. After the automotive accessories are clamped and fixed, the limit block 905 is aligned with another limit groove 902. At this time, under the action of the second resetting mechanism, the limit block 905 is inserted into another limit groove 902, and the limit block 905 is abutted against the side wall of the limit groove 902, thereby preventing the hinge shaft 102 and the handle 103 from rotating clockwise, thereby preventing the rubber head 108 from loosening and ensuring the clamping effect.

[0041] The second reset mechanism includes a fixed block 1002 fixedly connected to the side wall of the base 101, and two symmetrically arranged third T-shaped guide rods 1001 are inserted on the top of the fixed block 1002, the upper end of the third T-shaped guide rod 1001 is fixed to the bottom of the moving block 904, and the side wall of each third T-shaped guide rod 1001 is sleeved with a third spring 1003, which guides and resets the movement of the moving block 904.

[0042] Working principle: When in use, when clamping and fixing the auto parts, rotate the handle 103 to rotate it counterclockwise along the hinge shaft 102, so that the pressure handle 105 rotates to a horizontal state, and the bolt 107 rotates to a vertical state. Then, the bolt 107 is raised and lowered by the clamp assembly 106, and then the rubber head 108 is raised and lowered, so that the rubber head 108 contacts the surface of the auto parts. Then, insert the hexagonal wrench into the hexagonal socket 305, and rotate the threaded rod 304. The rotation of the threaded rod 304 drives the threaded tube 303 to move downward, thereby driving the first movable disk 12 to move downward, and then pushing the first sleeve rod 1502 to move downward along the first sleeve tube 1501. At the same time, the reset spring 1503 is compressed, so that the rubber head 108 can provide a clamping force to the auto parts through the second movable disk 13 and the mounting seat 14;

[0043] At the same time, when the first movable plate 12 moves downward, the push pin 203 slides in the sliding groove 202, thereby pushing the first pointer 1506 to rotate downward along the rotating shaft 1505. At this time, by observing the first scale mark 1508 pointed to by the first pointer 1506, the clamping force of the rubber head 108 on the automobile accessories can be controlled, so that it is easy to adjust and control the clamping force of the rubber head 108 on the automobile accessories, and the use effect is better. After the adjustment is completed, in the subsequent clamping process, under the action of the reset spring 1503, a pre-tightening force can be provided, so that the clamping effect is better;

[0044] Furthermore, when the first movable plate 12 is moved downward by the lifting mechanism during adjustment, the clamping force of the rubber head 108 on the automobile parts is adjusted, and the indicator plate 401 is driven to move downward synchronously. At this time, the second scale mark 402 pointed to by the second pointer 404 is the initial position;

[0045] After each clamping is completed, observe the first scale mark 1508 pointed to by the first pointer 1506. When the first pointer 1506 deflects downward to the initial position, it indicates that there may be foreign matter between the rubber head 108 and the auto part, and it needs to be cleaned to ensure the clamping and fixing effect. When the first pointer 1506 deflects upward to the initial position, it indicates that the rubber head 108 is worn and the clamping force between the rubber head 108 and the auto part becomes smaller. At this time, the first movable plate 12 can be moved downward continuously by the lifting mechanism, so that the first pointer 1506 points to the initial first scale mark 1508 again, so that the wear of the rubber head 108 can be compensated to ensure the clamping and fixing effect.

[0046] When the rubber head 108 is worn, the first movable plate 12 is moved downwards by the lifting mechanism, and the indicator plate 401 is driven to move downwards. The wear amount of the rubber head 108 can be determined by the change of the second scale mark 402 pointed by the second pointer 404. When the wear amount is large, the rubber head 108 is removed and replaced to ensure the clamping and fixing effect.

[0047] Furthermore, when clamping and fixing the automobile accessory, the handle 103 is rotated to rotate counterclockwise along the hinge shaft 102, so that the pressure handle 105 is rotated to a horizontal state, and the bolt 107 is rotated to a vertical state. At the same time, when the hinge shaft 102 rotates, the fixing ring 901 is driven to rotate synchronously. When the third inclined surface 903 and the fourth inclined surface 906 abut against each other, the limit block 905 can be pushed to move downward, and at the same time, the moving block 904 is driven to move downward. The third spring 1003 is compressed, and the limit block 905 is withdrawn from the limit groove 902 and slides on the side wall of the fixing ring 901. After the automobile accessory is clamped and fixed, the limit block 905 and the other One limiting groove 902 is aligned. At this time, under the action of the third spring 1003, the limiting block 905 is inserted into the other limiting groove 902, and the limiting block 905 is abutted against the side wall of the limiting groove 902, so that the hinge shaft 102 and the handle 103 can be prevented from rotating clockwise, thereby preventing the rubber head 108 from loosening and ensuring the clamping effect. When the auto part needs to be loosened, the moving block 904 is first pushed downward to make the limiting block 905 withdraw from the limiting groove 902, and then the handle 103 can be rotated clockwise, thereby driving the pressing handle 105 to rotate upward, and then the rubber head 108 is separated from the auto part;

[0048] When the rubber head 108 needs to be installed, the rectangular block 501 is inserted into the rectangular hole 503. When the rectangular block 501 abuts against the first inclined surface 506, the plurality of card blocks 505 can be pushed to move outward along the installation hole 504. At the same time, the second spring 603 is compressed. When the rectangular block 501 abuts against the sliding plate 507, the sliding plate 507 can be pushed to move upward. At the same time, the first spring 508 is compressed. When the card slot 502 is aligned with the card block 505, the card block 505 is inserted into the card slot 502 under the action of the second spring 603. Under the action of the spring 508, the slot 502 is abutted against the top of the block 505, so that the rectangular block 501 can be limited, making the installation of the rubber head 108 more convenient and quick. When the rubber head 108 needs to be disassembled and replaced, the pushing ring 703 is pushed to move downward and abut against the second inclined surface 702. The pushing block 701 can drive the block 505 to move outward along the installation hole 504 and withdraw from the slot 502. Then, the rubber head 108 can be removed, thereby facilitating the installation and disassembly of the rubber head 108, and the use is more convenient and quick.
