It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0023] The utility model provides a tool changing and preventing hand injury protection device, such as Figure 1-6 As shown, the tool-changing hand injury protection device comprises: a handle 1, wherein a threaded groove is axially provided in the handle 1, and a sliding sleeve 2 is provided on the outer sliding sleeve of the handle 1; a screw rod 3 rotatably installed in the sliding sleeve 2, wherein the screw rod 3 is threadably matched with the threaded groove, and one end of the screw rod extends out from one end of the sliding sleeve; a cutter protection cover 4 welded on one end of the handle 1 for preventing hand injuries, wherein a mounting groove 5 is provided in the center of the bottom surface of the cutter protection cover 4, and a screw hole 6 is provided on the top of the mounting groove 5; a nut sleeve 7 for removing the screw is arranged above the mounting groove and the screw hole; and two fixing mechanisms are mounted on the top surface of the cutter protection cover 4 for fixing the nut sleeve 7.
[0024] In this embodiment, when the protective device is used to replace the blade on the cutting device, the sliding sleeve 2 is held by hand to pick up the entire device, and then the cutter protection cover 4 is put on the blade of the cutting device. The screw in the middle of the blade can enter the nut sleeve 7 from the screw hole 6, and then the handle 1 can be turned to make the handle 1 drive the cutter protection cover 4 and the nut sleeve 7 to rotate, so that the nut sleeve 7 can be turned to loosen the screw fixing the blade. During this operation, since the cutter protection cover 4 is put on the outside of the blade of the cutting device, it can prevent the blade from contacting the employee's hand, thereby solving the problem of hand injury when the employee uses a wrench to replace the blade with bare hands, and it is safer to use. If the employee wants to adjust the length between the handle 1 and the sliding sleeve 2, he only needs to rotate the screw rod 3 to make the sliding sleeve 2 slide on the handle 1, so that the length between the handle 1 and the sliding sleeve 2 can be changed, so that different employees can adapt to the device when using it, and the adjustment is convenient. If different types of nut sleeves 7 are used, two fixing mechanisms are required to release the fixation of the nut sleeve 7. After releasing, the nut sleeve 7 can be taken out of the mounting groove 5, and then other types of nut sleeves 7 can be put in, and then two fixing mechanisms are used to fix it, which is convenient to replace, so that the device can screw different types of screws, has a better use effect, and has better versatility.
[0025] In a further preferred embodiment of the utility model, the fixing mechanism includes: a shell 8 symmetrically distributed on the top surface of the cutter protection cover 4 on both sides of the nut sleeve, and a pull rod 9 extending toward the nut sleeve is slidably mounted on the shell 8; a pressure block 10 welded to one end of the pull rod 9 close to the nut sleeve, and an open groove for the pressure block to pass through is provided on one side of the shell close to the nut sleeve, so that the pressure block 10 is in contact with the nut sleeve 7; a spring 11 slidably sleeved on the pull rod 9, and the spring 11 is located between the inner wall of the shell 8 away from the nut sleeve and the pressure block.
[0026] In this embodiment, the fixing mechanism is used to fix the nut sleeve 7. When it is necessary to replace the nut sleeve 7 with another type, the pull rod 9 needs to be pulled. The pull rod 9 will drive the pressure block 10 to move toward the inside of the shell 8 and squeeze the spring 11. When the pressure block 10 is detached from the surface of the nut sleeve 7, the nut sleeve 7 can be taken out of the mounting groove 5. Then, other types of nut sleeves 7 are placed into the mounting groove 5. After placement, the pull rod 9 is released to allow the spring 11 to push the pressure block 10 to move through elasticity, so that the pressure block 10 contacts the nut sleeve 7. In this way, the nut sleeve 7 can be stably installed in the mounting groove 5, and the operation is relatively convenient and quick.
[0027] In a further preferred embodiment of the utility model, a slide groove 12 is provided on both inner walls of the housing 8 parallel to the pull rod, a slider 13 is slidably mounted on the inner wall of the slide groove 12 , and the slider 13 is fixedly connected to the pressure block 10 .
[0028] In this embodiment, slide grooves 12 are provided on the inner walls on both sides of the two shells 8, and sliders 13 are slidably installed on the inner walls of these slide grooves 12. These sliders 13 are fixedly connected to the two pressure blocks 10 respectively. When the pull rod 9 is operated, it will drive the pressure blocks 10 to move together, and the pressure blocks 10 slide in the slide grooves 12 through the sliders 13. This design ensures the stability of the pressure blocks 10 during the movement and will not tilt during the movement.
[0029] In a further preferred embodiment of the present invention, a handle 14 is fixedly mounted on one end of the pull rod 9 away from the pressing block, and the handle 14 is configured to be cylindrical.
[0030] In this embodiment, handles 14 are fixedly installed at the ends of the two pull rods 9 that are away from each other, and the two handles 14 are both designed to be cylindrical. The introduction of the handles 14 makes it easier for the user to hold and apply force during operation, thereby more smoothly controlling the movement of the pull rods 9. The cylindrical design is easy to grasp and provides a comfortable touch.
[0031] In a further preferred embodiment of the present invention, a knob 15 is fixedly mounted on one end of the screw rod 3 away from the cutter protection cover, and a plurality of anti-slip sheets are arranged on the knob 15 .
[0032] In this embodiment, a knob 15 is fixedly mounted at one end of the screw rod 3, and a plurality of anti-slip sheets are arranged on the knob 15. The introduction of the knob 15 enables the user to control the rotation of the screw rod 3 by rotating it, thereby adjusting the position of the sleeve 2 on the handle 1. Since the diameter of the knob 15 is larger than that of the screw rod 3, the user can more easily grasp and apply rotational force, thereby improving the convenience of operation. In addition, the plurality of anti-slip sheets arranged on the knob 15 further enhance the stability and safety of the operation. The anti-slip sheets are usually made of a material with a good friction coefficient, which can increase the friction between the knob 15 and the palm and prevent slipping during rotation.
[0033] In a further preferred embodiment of the present invention, a soft sleeve 16 is fixedly mounted on the sliding sleeve 2 and is made of rubber.
[0034] In this embodiment, a soft cover 16 is fixedly mounted on the sliding sleeve 2, and the soft cover 16 is made of rubber material. The rubber soft cover 16 has good elasticity and softness, and can provide the user with a more comfortable grip. At the same time, the rubber material also has good anti-slip performance, and can effectively prevent slipping during operation, thereby ensuring the stability and safety of the operation.
[0035] In a further preferred embodiment of the present invention, the two springs 11 are made of stainless steel, and the two pressing blocks 10 are both rectangular.
[0036] In this embodiment, the spring 11 made of stainless steel has excellent corrosion resistance, elasticity and wear resistance. During long-term use, the spring 11 can maintain stable elasticity and performance and is not easy to rust or damage, thereby ensuring the reliability and durability of the fixing mechanism. The rectangular-shaped pressure block 10 provides a more stable and uniform contact surface. When fixing the nut sleeve 7, the rectangular pressure block 10 can better fit the surface of the nut sleeve 7.
[0037] To sum up, compared with the related art, the present invention can facilitate employees to rotate the screw rod 3 through the knob 15. The rotation of the screw rod 3 can adjust the length between the handle 1 and the sleeve 2, so that different employees can adapt to the device and the adjustment is convenient. By putting the cutter protection cover 4 on the blade of the cutting device and putting the nut sleeve 7 on the screw of the blade, the employee can use the handle 1 to rotate the entire device so that the nut sleeve 7 can loosen the screw that fixes the blade. During this operation, since the cutter protection cover 4 is put on the outside of the blade of the cutting device, it can prevent the blade from contacting the employee's hand, thereby solving the problem of employees injuring their hands when using a wrench to replace the blade with their bare hands. It is safer to use. The fixing mechanism can facilitate employees to replace the corresponding type of nut sleeve 7 according to the screw to be screwed, so that the device can screw different types of screws, with better use effect and better versatility.
