[0029] Reference Figure 1 As shown, the utility model provides a technical solution: a spring pressure clamp, including a first clamp plate 1, the interior of the first clamp plate 1 is fixedly connected to a rotating shaft, the outer side of the rotating shaft is rotatably connected to a second clamp plate 2, the outer side of the rotating shaft is sleeved with a torsion spring 3, and the torsion spring 3 is located between the first clamp plate 1 and the second clamp plate 2.

[0030] The following is a detailed description of its overall specific settings and functions.

[0031] Reference Figure 1-Figure 4As shown, in this embodiment: the first clamping plate 1 is internally threadedly connected with a screw rod 8, and the second clamping plate 2 is internally slidably penetrated with a drawstring 5. By setting the above structure, the stable expansion of the larger jaw of the spring pressure clamp is facilitated, and the situation that the jaw of the spring pressure clamp is easily closed due to hand slippage during the process of pressing the larger jaw of the spring pressure clamp is avoided, thereby improving the safety of the spring pressure clamp during use.

[0032] The first clamping plate 1 is internally slidably connected to the moving frame 4, and the screw rod 8 is internally rotatably connected to the moving frame 4. The moving frame 4 is provided to realize the movement of the pull rope 5, and the twisting of the pull rope 5 can be avoided. The upper surface of the moving frame 4 is fixedly connected to the fixing rod 10, and the upper end of the fixing rod 10 is fixedly connected to the baffle 11. The side wall of the baffle 11 is evenly provided with a plurality of slots 12, and the lower end of the pull rope 5 is fixedly connected to the sphere 13. When the sphere 13 on the pull rope 5 moves to the bottom of the baffle 11, the pull rope 5 will be sleeved on the inner side of the slot 12 on the baffle 11, and the sphere 13 will be stuck under the baffle 11. At this time, the pull rope 5 can be hooked, avoiding the situation that the clamp is easily closed after opening.

[0033] The lower end of the screw rod 8 is fixedly connected to the rotating plate 6, and the side wall of the rotating plate 6 is evenly fixedly connected with four protrusions 9. The rotating plate 6 is twisted, and the protrusions 9 on the rotating plate 6 increase the friction between the hand and the rotating plate 6, which facilitates the twisting work of the rotating plate 6. The surface of the rotating plate 6 is provided with a groove 7. By providing the groove 7 on the rotating plate 6, the pressing work on the surface of the first clamping plate 1 is facilitated.

[0034] Reference Figure 1 and Figure 4 As shown, specifically, a positioning block 14 is fixedly connected to the surface of the second clamping plate 2, a screw 15 is connected to the internal thread of the positioning block 14, and the other end of the pull rope 5 is fixedly connected to the screw 15. By rotating the screw 15 inside the positioning block 14, the pull rope 5 on the screw 15 can be wound, which further facilitates the adjustment of the distance between the ball 13 and the baffle 11. A circular plate 16 is fixedly connected to the end face of the screw 15. By setting the circular plate 16, the shielding work of the pull rope 5 wound on the end side of the screw 15 can be achieved, and the pull rope 5 can be prevented from falling off the screw 15.

[0035] Working principle: when the spring pressure clamp jaws need to be opened at a larger angle, first press the first clamping plate 1 and the second clamping plate 2 toward each other; when the ball 13 on the pull rope 5 moves to the bottom of the baffle 11, the pull rope 5 will be sleeved on the inner side of the slot 12 on the baffle 11, and the ball 13 will be stuck under the baffle 11; at this time, the pull rope 5 can be hooked to avoid the situation where the jaws are easily closed after opening; twist the turn plate 6, and the protrusion 9 on the turn plate 6 increases the friction between the hand and the turn plate 6, which facilitates the twisting work of the turn plate 6; the turn plate 6 drives the screw 8 to rotate, which facilitates the driving work of the mobile frame 4; by setting the mobile frame 4 To realize the movement of the pull rope 5, the twisting of the pull rope 5 can be avoided. By pulling the pull rope 5, the clamping gap can be stably enlarged. By setting the groove 7 on the rotating plate 6, the pressing work on the surface of the first clamping plate 1 is facilitated. At the same time, the staff can drive the rotating plate 6 in the opposite direction to realize the reduction of the clamping gap, which is convenient for the stable clamping of the object to be clamped. By setting the above structure, the stable expansion of the larger clamping gap of the spring pressure clamp is facilitated, and the situation that the hand slips easily during the pressing process of the larger clamping gap of the spring pressure clamp, which leads to the rapid closing of the clamping gap of the spring pressure clamp, is avoided, thereby improving the safety of the spring pressure clamp during use.

[0036] By rotating the screw rod 15 inside the positioning block 14, the winding work of the pull rope 5 on the screw rod 15 can be realized, which further facilitates the adjustment of the distance between the sphere 13 and the baffle 11, and facilitates the stable expansion of the larger clamping mouth of the spring pressure clamp by different personnel, further improving the performance of the spring pressure clamp. By setting the circular plate 16, the shielding work of the pull rope 5 wound on the end side of the screw rod 15 can be achieved, and the pull rope 5 can be avoided from falling off the screw rod 15. By setting the above structure, the control of the use length of the pull rope 5 is facilitated, thereby facilitating the operation of different personnel to continue to expand the clamping mouth of the spring pressure clamp after expanding the spring pressure clamp to a certain angle.
