The fixing frame 13 is hung on the tubular object, and the turntable 17 is rotated to rotate the first screw rod 16. At this time, the connecting column 18 and the extrusion plate 19 move upward, and the extrusion plate 19 contacts the tubular object. The turntable 17 continues to be rotated until the signal generator body 1 is fixed. By setting the fixing frame 13 and the first screw rod 16, when the equipment is installed in outdoor areas, such as roofs, towers, etc., the process of installing the equipment by the staff can be simplified, which is convenient for the staff to use the equipment, and reduces the situation where the staff needs to hold the equipment during long-term testing, reduces the soreness of the staff's arms caused by long-term handholding, and reduces the difficulty of the staff to use the equipment.

[0029] Further, such as Figure 1 and Figure 3 As shown, the bottom of the outer wall of the signal generator body 1 is fixedly connected to a first connecting tube 2; the inner wall of the first connecting tube 2 is threadedly connected to a first threaded column 21; the bottom of the outer wall of the turntable 17 is fixedly connected to a first fixing column 22; the inner wall sliding rod of the first fixing column 22 is connected to a connecting rod 23; the connecting rod 23 can be detached from the first fixing column 22; the inner wall of the first threaded column 21 is fixedly connected to a first internally threaded tube 24; the inner wall of the connecting rod 23 is fixedly connected to a second internally threaded tube 25. The device can be lifted by passing the connecting rod 23 through the first fixed column 22 and connecting the first threaded column 21 with the first connecting pipe 2. At this time, when the connecting rod 23 is rotated, the turntable 17 will rotate accordingly. By setting the connecting rod 23 and the first threaded column 21, when the staff needs to place the device at a high place, the staff does not have to climb to the same height to complete the installation of the device. At the same time, by connecting the first internal threaded tube 24 and the second internal threaded tube 25, the rising height of the device can be further extended, which is convenient for the staff to complete the installation of the equipment according to the actual situation, reduces the number of times the staff climbs, reduces the probability of the staff accidentally falling during the climbing process, and increases the practicality and convenience of the equipment.

[0030] Further, such as Figure 4As shown, a pair of spring columns 3 are fixedly connected to the side wall of the slider 12; the spring columns 3 do not contact the first notch 32; the outer wall of the spring column 3 is fixedly connected to the first fixing block 31; the outer wall of the limit plate 11 is provided with a first notch 32; the first fixing block 31 is in sliding contact with the first notch 32.

When the slider 12 moves to the fixed position, the first fixing block 31 and the first notch 32 are also at the same height. At this time, the limit plate 11 loses the pressure on the first fixing block 31, and the first fixing block 31 pops outward and contacts the first notch 32 to fix the slider 12. By setting the first fixing block 31 and the first notch 32, after the process of the staff sliding and installing the slider 12 is completed, the first fixing block 31 and the first notch 32 form a fixation for the slider 12.

By setting the connecting ring 4 and the bristles 41, the outer side wall of the first screw rod 16 can be cleaned when it is working, reducing impurities adhering to the outer side wall of the first screw rod 16, reducing the jamming phenomenon during the rotation of the first screw rod 16, increasing the smoothness of the device operation, and reducing the probability of device failure.

[0032] Further, such as Figure 6 As shown, the top of the outer wall of the connecting column 18 is threadedly connected with an external thread column 5; the external thread column 5 can be detached from the connecting column 18; the external thread column 5 passes through the extrusion plate 19; the top of the outer wall of the fixing frame 13 is bolted with a conical fixing column 51; the conical fixing column 51 can be detached from the fixing frame 13. When the device is installed on a tree branch, the rotation of the first screw rod 16 will drive the external thread column 5 to rotate, so that the external thread column 5 extends into the inside of the tree branch, and the conical fixing column 51 will also penetrate into the inside of the tree branch to a certain extent. By setting the external thread column 5 and the conical fixing column 51, when the device is installed on the tree branch, the connection between the device and the tree branch can be strengthened, reducing the swaying of the tree branch when encountering the wind, which may cause the device to fall off, and increasing the stability of the device.

[0033] Further, such as Figure 6As shown, a plurality of plastic columns 6 are fixedly connected to the top of the outer wall of the extrusion plate 19; a plastic plate 61 is fixedly connected to the inner wall of the fixing frame 13; and the plastic plate 61 is penetrated by the conical fixing column 51. When installing the equipment, when encountering a metal surface, the external thread column 5 and the conical fixing column 51 are removed to make the plastic column 6 and the plastic plate 61 contact the metal surface. The friction between the equipment and the metal surface is increased by the set plastic column 6 and the plastic plate 61, so that the equipment can work more stably, reduce the situation where the equipment is unstable in connection with the metal surface due to insufficient friction, and increase the practicality of the equipment.

[0034] Further, such as Figure 7 As shown, the inner wall of the limit plate 11 is provided with a ball bearing 7; the ball bearing 7 rotates on the side wall of the limit plate 11; the ball bearing 7 cannot be separated from the limit plate 11; the ball bearing 7 contacts the slider 12. When the device is working, the slider 12 and the limit plate 11 will slide and rub against each other. The ball bearing 7 is provided to convert the sliding friction between the slider 12 and the limit plate 11 into rolling friction, which reduces the difficulty for the staff to install the device and facilitates the staff to install the device.

[0035] Working principle: hang the fixing frame 13 on the tubular object, turn the turntable 17 to rotate the first screw rod 16, then the connecting column 18 and the extrusion plate 19 move upward, the extrusion plate 19 contacts the tubular object, and continue to turn the turntable 17 until the signal generator body 1 is fixed. By setting the fixing frame 13 and the first screw rod 16, when the equipment is installed in outdoor areas, such as roofs, towers, etc., the process of installing the equipment by the staff can be simplified, which is convenient for the staff to use the equipment, and the situation that the staff needs to hold the equipment during long-term testing can be reduced, which can reduce the pain of the staff's arms caused by long-term hand-holding, and reduce the difficulty of the staff to use the equipment.

At this time, when the connecting rod 23 is rotated, the turntable 17 will rotate accordingly. Through the setting of the connecting rod 23 and the first threaded column 21, when the staff needs to place the device at a high place, the staff does not have to climb to the same height to complete the installation of the device. At the same time, the height of the device can be further extended by connecting the first internally threaded tube 24 and the second internally threaded tube 25, which is convenient for the staff to complete the installation of the device according to actual conditions, reduces the number of times the staff climbs, reduces the probability of the staff accidentally falling during the climbing process, and increases the practicality and convenience of the equipment. During the upward sliding of the slider 12, the first fixing block 31 is squeezed, thereby squeezing the spring column 3, and when the slider 12 moves When the first fixing block 31 and the first notch 32 are moved to the fixed position, the first fixing block 31 and the first notch 32 are also at the same height. At this time, the limiting plate 11 loses the pressure on the first fixing block 31, and the first fixing block 31 pops outward and contacts with the first notch 32 to fix the sliding block 12. Through the first fixing block 31 and the first notch 32, after the worker slides and installs the sliding block 12, the first fixing block 31 and the first notch 32 form a fixation for the sliding block 12. When the worker installs the equipment at a high place, the situation that the sliding block 12 is separated from the limiting plate 11 due to careless operation is reduced, the failure rate of the equipment is reduced, and the worker is convenient to use the equipment. When the equipment is working, the first screw rod 16 will rotate, and the bristles 41 will rub against the first screw rod 16 through the connection set The ring 4 and the bristles 41 can clean the outer wall of the first screw rod 16 when it is working, reduce the impurities adhering to the outer wall of the first screw rod 16, reduce the jamming phenomenon during the rotation of the first screw rod 16, increase the smoothness of the equipment operation, and reduce the probability of equipment failure. When the equipment is installed on a tree branch, the rotation of the first screw rod 16 will drive the external thread column 5 to rotate, so that the external thread column 5 extends into the interior of the branch, and the conical fixing column 51 will also penetrate into the interior of the branch to a certain extent. By setting the external thread column 5 and the conical fixing column 51, when the equipment is installed on the tree branch, the connection between the equipment and the tree branch can be strengthened, the swaying of the tree branch when encountering the wind can be reduced, and the equipment can be increased. The stability of the equipment is increased. When the equipment is installed, when a metal surface is encountered,Remove the external thread column 5 and the conical fixing column 51, so that the plastic column 6 and the plastic plate 61 are in contact with the metal surface. The friction between the device and the metal surface is increased by setting the plastic column 6 and the plastic plate 61, so that the device can work more stably, reduce the situation that the device and the metal surface are unstable due to insufficient friction, and increase the practicality of the device. When the device is working, the slider 12 and the limit plate 11 will slide and rub.
