However, this kind of protection has poor practicability, is easy to be damaged after being collided, and the damaged protection shell may scratch the wires. Moreover, the existing devices have poor stability, are prone to displacement after being impacted, and the installation is rather cumbersome, which is not conducive to the protection of wires.

[0020] Refer to Figures 1-4 , a protection device for exposed wires in electrical engineering, comprising a protection housing 1. A limit hole 2 is opened at the top of the protection housing 1, and a connector 3 is rotatably installed in the limit hole 2; A left - hand and right - hand thread ball screw 4 is rotatably installed on one inner wall of the protection housing 1, and a plurality of limit metal strips 7 are slidably installed on one inner wall of the protection housing 1. Corresponding positioning housings 6 are respectively and fixedly installed on one sides of the plurality of limit metal strips 7; Two fixing holes are opened on both sides of the protection housing 1, and sleeves 13 are slidably installed in the plurality of fixing holes. Fixed heads 14 are fixedly sleeved on the outer sides of the plurality of sleeves 13, and hexagonal hole grooves are opened at the tops of the plurality of fixed heads 14.

[0021] In this embodiment, lifting holes are opened at the tops of the two positioning housings 6, and slide blocks 5 are fixedly installed in the two lifting holes.

[0022] In this embodiment, the two slide blocks 5 are both threadedly sleeved on the same left - hand and right - hand thread ball screw 4. One end of the left - hand and right - hand thread ball screw 4 is connected to the connector 3. A cross slot 18 is opened at the top of the connector 3, which is convenient for driving the left - hand and right - hand thread ball screw 4 to rotate through the connector 3.

[0023] In this embodiment, limit housings 8 are respectively and fixedly installed on the sides of the two positioning housings 6 close to each other. Connecting holes are opened at the bottoms of the two limit housings 8, and connecting columns 10 are slidably installed in the two connecting holes. Connecting springs 9 are fixedly installed on one inner walls of the two connecting holes, and one ends of the two connecting springs 9 are respectively and fixedly installed on one ends of the corresponding connecting columns 10.

[0024] In this embodiment, limit clamps 11 are fixedly installed at one ends of the two connecting columns 10, and a plurality of limit springs 12 are fixedly installed on the outer sides of the two limit clamps 11. One ends of the plurality of limit springs 12 are respectively and fixedly installed on the corresponding limit housings 8, which is convenient for alleviating the impact force and can better limit the wire at the same time.

[0025] In this embodiment, nuts 16 are fixedly installed on the inner sides of multiple sleeves 13, threaded rods 17 are slidably installed inside the multiple sleeves 13, the multiple threaded rods 17 are respectively threadedly connected to the corresponding nuts 16, and cross grooves 18 are formed at the tops of the multiple threaded rods 17, facilitating the staff to drive the threaded rods 17 to rotate through a cross-shaped drill bit.

[0026] In this embodiment, multiple sliding holes are formed in the outer sides of the multiple sleeves 13, limiting metal blocks 15 are slidably installed in the multiple sliding holes, and drill cones 19 are fixedly installed at one ends of the multiple sleeves 13, facilitating the multiple sleeves 13 to be driven into a wall or the ground.

[0027] Working principle: During installation, after the staff places the protective housing 1 at a designated position, the multiple sleeves 13 are placed in corresponding fixing holes. Subsequently, the staff first uses a drill tool adapted to the hexagonal hole groove at the top of the fixing head 14 to drive the sleeve 13 to rotate through the tool. The rotation of the sleeve 13 drives the drill cone 19 to rotate and penetrate into the ground or the wall. Subsequently, the staff replaces the tool drill bit with a cross-shaped one, which is adapted to the cross groove 18 formed at the top of the threaded rod 17. Then, the cross-shaped drill bit is used to drive the threaded rod 17 to rotate. Since the nut 16 is fixed, the threaded rod 17 rotates and moves downward through the nut 16. The movement of the threaded rod 17 drives the multiple limiting metal blocks 15 to slide outward under extrusion, helping to fix the sleeve 13 and prevent it from falling off or moving. Subsequently, the staff passes the wire through the device. After adjusting the position, the staff uses the cross-shaped drill bit to control the rotation of the connector 3. The rotation of the connector 3 drives the left and right hand threaded ball screw 4 to rotate. The rotation of the left and right hand threaded ball screw 4 drives the two sliders 5 to approach each other. The two sliders 5 approaching each other drive the corresponding positioning housings 6 to approach each other. The two positioning housings 6 approaching each other drive the corresponding limiting housings 8 to approach each other. The two limiting housings 8 approaching each other drive the corresponding limiting clips 11 to clamp the wire, ensuring the stability of the wire. When impacted or in other situations, the multiple limiting springs 12 can be relied on to relieve and offset the impact force to protect the wire.

[0028] The technological progress obtained by the present utility model compared with the prior art is that the device can protect the bent corners of the wire, prevent damage when impacted or in other situations, effectively improve the practicability of the device, and can fix the device better and more quickly. After installation, the stability and impact resistance are high, and the wire can be protected more effectively.
