Detailed implementation

[0022] The present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0023] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0024] Refer to Figure 1 As shown, a toad clamp in a preferred embodiment of the present utility model includes a first clamp 1. The rear end of the first clamp 1 is detachably connected to a second clamp 2, and the rear end of the second clamp 2 is installed with a third clamp 3; a T-shaped block 11 is fixedly connected to the rear end of the first clamp 1, and a T-shaped groove 12 is opened at the front end of the second clamp 2. The T-shaped groove 12 is adapted to the T-shaped block 11, and the T-shaped block 11 is inserted into the interior of the T-shaped groove 12;

[0025] By inserting the T-shaped block at the rear end of the first clamp 1 into the T-shaped groove at the front end of the second clamp 2, the cooperation design of the T-shaped block and the T-shaped groove enables the two to be tightly connected.

[0026] Refer to Figure 2 As shown, an insertion groove 13 is opened at the rear end of the first clamp 1.

[0027] Refer to Figure 1 、 Figure 2 As shown, a C-port groove 6 is opened at the top end of the second clamp 2. An insertion rod 7 is threadedly connected inside the C-port groove 6. The insertion rod 7 passes through the C-port groove 6 and extends into the insertion groove 13, and the insertion rod 7 is threadedly connected to both the C-port groove 6 and the insertion groove 13;

[0028] Screw the insertion rod 7 into the C-port groove at the top of the second clamp 2, and make it extend through the C-port groove into the insertion slot 13 at the rear end of the first clamp 1. This further enhances the connection stability between the first clamp 1 and the second clamp 2, prevents the two from separating when clamping workpieces, and is not prone to relative sliding during use. Then, the fixing bolts 10 on both sides of the T-shaped groove penetrate through the second clamp 2 and are screwed into the inside of the first clamp 1, strengthening the connection between the first clamp 1 and the second clamp 2 from the side. When the first clamp 1 and the second clamp 2 are assembled, the clamping area of the entire toad clamp increases. When clamping workpieces, the clamping parts of the first clamp 1 and the second clamp 2 act together to clamp more and larger workpieces. Conversely, after removing the insertion rod 7, the T-shaped block can be separated from the T-shaped groove at the front end of the second clamp 2. Therefore, the first clamp 1 and the second clamp 2 can be separated, and the user can use the first clamp 1 and the second clamp 2 separately, which can adapt to different working environments and clamping requirements. It can be used alone in a narrow space or assembled for use when clamping larger workpieces.

[0029] Refer to Figure 1 As shown, a through hole 4 is provided at the top of the first clamp 1, and a bolt rod 5 is threadedly connected inside the through hole 4.

[0030] Refer to Figure 2 、 Figure 3 As shown, a pair of screw holes 8 are provided at the rear end of the third clamp 3, and a limit bolt 9 is threadedly connected inside the screw holes 8. The limit bolt 9 extends through the screw holes 8 into the inside of the second clamp 2, and the limit bolts 9 are threadedly connected to both the screw holes 8 and the second clamp 2;

[0031] By loosening the bolt 9, the third clamp 3 can be separated from the second clamp 2. The workpiece can be placed between the third clamp 3 and the second clamp 2, and then the bolt 9 is tightened to clamp the tiny workpiece.

[0032] Refer to Figure 1 As shown, fixing bolts 10 are installed on both sides of the T-shaped groove 12 at the top of the second clamp 2. The fixing bolts 10 penetrate through the second clamp 2 and extend into the inside of the first clamp 1. The fixing bolts 10 are threadedly connected to both the second clamp 2 and the first clamp 1.

[0033] Specific implementation process: First, when in use, according to the actual situation, the user can choose to use the whole composed of the first clamp 1, the second clamp 2 and the third clamp 3 alone, or assemble and use the first clamp 1 and the second clamp 2. By inserting the T-shaped block at the rear end of the first clamp 1 into the T-shaped groove at the front end of the second clamp 2, the design of the cooperation between the T-shaped block and the T-shaped groove enables the two to be tightly connected. At the same time, screw the insertion rod 7 into the C-port groove at the top of the second clamp 2 and make it extend through the C-port groove into the insertion slot 13 at the rear end of the first clamp 1, which further enhances the connection stability between the first clamp 1 and the second clamp 2, prevents the two from separating when clamping the workpiece, and is not prone to relative sliding during use. Then, the fixing bolts 10 on both sides of the T-shaped groove penetrate the second clamp 2 and are screwed into the inside of the first clamp 1, strengthening the connection between the first clamp 1 and the second clamp 2 from the side. When the assembly of the first clamp 1 and the second clamp 2 is completed, the clamping area of the whole toad clamp increases. When clamping the workpiece, the clamping parts of the first clamp 1 and the second clamp 2 act together to clamp more and larger workpieces. On the contrary, after removing the insertion rod 7, the T-shaped block can be separated from the T-shaped groove at the front end of the second clamp 2. Therefore, the first clamp 1 and the second clamp 2 are separated, and the user can use the first clamp 1 and the second clamp 2 alone, which can adapt to different working environments and clamping requirements. It can be used alone in a narrow space or assembled for clamping larger workpieces. Among them, loosen the bolt 9 to separate the third clamp 3 from the second clamp 2, place the workpiece between the third clamp 3 and the second clamp 2, and then tighten the bolt 9 to clamp the small workpiece. During use, it is applicable to clamping a variety of different workpieces, making the use more convenient and facilitating the user to clamp more types of workpieces.
