[0026] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-Figure 7 The utility model proposes an anti-pinching tweezers, including a base 1, a limiting groove 15 is provided on the base 1, a moving rod 2 is slidably connected to the base 1, the moving rod 2 is provided with a slot 23, the moving rod 2 is slidably connected to a clamping arm 3, the bottom end of the clamping arm 3 is penetrated by a clamping plate 4 and is slidably connected to the clamping plate 4, a spring 6 5 is fixedly connected to the outer wall of the clamping plate 4, and one end of the spring 6 5 away from the clamping plate 4 is fixedly connected to the inner wall of the clamping arm 3.
[0029] In the embodiment of the utility model, in order to clamp the LED chip, specifically, the base 1 is provided with a second clamping rod 13, the second clamping rod 13 is provided with a clamping groove 131, the second clamping rod 13 is slidably connected to the inner wall of the base 1, a spring 12, one end of the spring 12 is fixedly connected to the outer wall of the second clamping rod 13, the other end of the spring 12 is fixedly connected to the inner wall of the base 1, the second clamping rod 13 is rotatably connected to the first clamping rod 11, the first clamping rod 11 is sleeve-connected to the base 1, the motion rod 2 is slidably connected to the third clamping rod 21, the outer wall of the third clamping rod 21 is fixedly connected to the third spring 22, one end of the third spring 22 away from the third clamping rod 21 is fixedly connected to the inner wall of the motion rod 2, and the motion rod 2 is provided with two groups, and the two groups of motion rods 2 are elastically connected by the second spring 14;
[0030] When the chip needs to be clamped, first press the moving rod 2 to make the moving rod 2 slide on the inner wall of the base 1. It should be noted that the moving rod 2 is provided with two groups. When the two groups of moving rods 2 are close to each other, the spring 2 14 undergoes elastic deformation. At the same time, during this process, the clamping rod 3 21 will be squeezed by the clamping groove 1 131, so that the clamping rod 3 21 slides toward the inside of the moving rod 2. At the same time, the spring 3 22 undergoes elastic deformation. When the clamping arm 3 clamps the chip, the clamping rod 3 21 coincides with the clamping groove 1 131. At this time, the clamping rod 3 21 will bounce into the inside of the clamping groove 1 131 under the elastic force of the spring 3 22, thereby completing the limitation of the moving rod 2.
[0031] like Figure 2 , Figure 3 and Figure 7 When the latch rod 11 is stuck in the limit groove 15, the spring 12 is in a stretched deformation state. When the limit of the moving rod 2 needs to be released, the latch rod 11 is rotated. At this time, the limit of the latch rod 11 is released. At this time, the latch rod 3 21 will move upward under the elastic force of the spring 3 22, so that the latch rod 3 21 is disengaged from the latch groove 131. During this process, the two sets of moving rods 2 will return to their original positions under the elastic force of the spring 2 14.
[0032] Further, the clamp arm 3 is slidably connected with a clamp block 31 and a pressure rod 34, a spring four 32 is fixedly connected to the outer wall of the clamp block 31, one end of the spring four 32 away from the clamp block 31 is fixedly connected to the inner wall of the clamp arm 3, a cross bar 35 is fixedly connected to the outer wall of the pressure rod 34, one end of the cross bar 35 away from the pressure rod 34 is fixedly connected to a spring five 33, one end of the spring five 33 away from the cross bar 35 is fixedly connected to the inner wall of the clamp arm 3, and the cross bar 35 passes through the clamp block 31 and is slidably connected to the clamp block 31;
[0033] When the length of the tweezers needs to be adjusted, a force is applied to the pressure rod 34 to make the pressure rod 34 move downward. When the pressure rod 34 moves downward, the cross bar 35 applies a force to the clamping block 31 to make the clamping block 31 slide into the clamping arm 3. It should be noted that the clamping block 31 is provided with a through slot and the length of the through slot is longer, and the cross bar 35 is set as an inclined surface. When the clamping block 31 is disengaged from the clamping slot 23, the limit of the clamping arm 3 is released. At this time, the length of the tweezers can be adjusted by pulling the clamping arm 3.
[0034] When the clamp arm 3 is in use, the pressure rod 34 is first pressed to make the cross rod 35 move. At this time, the cross rod 35 applies a force to the block 31, so that the block 31 slides into the inside of the clamp arm 3. When the block 31 is disengaged from the second clamping slot 23, the limit of the clamp arm 3 is released. At this time, the length of the tweezers can be adjusted by pulling the clamp arm 3, and then the moving rod 2 is pressed to make the moving rod 2 slide on the inner wall of the base 1. During this process, the clamp rod 3 21 will be squeezed by the clamping slot 1 131, so that the clamp rod 3 21 slides into the inside of the moving rod 2. When the clamp arm 3 clamps the chip, the clamp rod 3 21 coincides with the clamping slot 1 131. At this time, the clamp rod 3 21 will bounce into the inside of the clamping slot 1 131 under the elastic force of the spring 3 22, and the chip can be clamped.
