the fixing mechanism (18) comprises a fixing groove (1801), a baffle plate (1802), a fixing bolt (1803), a threaded shaft (1804), a cylindrical hole (1805) and a gear knob (1806), wherein the fixing groove (1801) is formed in the inner portion, far away from one side of the through hole (2), of the protection frame (1), the baffle plate (1802) is arranged in the protection frame (1801), the fixing bolt (1803) penetrates through the inner portion of the baffle plate (1802), the threaded shaft (1804) is fixed to the edge of one end of the baffle plate (1802), and the penetrating cylindrical hole (1805) is connected with the gear knob (1806);
the inside of the gear knob (1806) is provided with threads, the inside cross-sectional dimension of the gear knob (1806) is matched with the cross-sectional dimension of the threaded shaft (1804), one end of the gear knob (1806) protrudes out of the edge surface of the protection frame (1), and the depth of a fixing groove (1801) below the gear knob (1806) is matched with the width of the baffle plate (1802);
the use method of the protection device comprises the following steps: firstly, a tester body (19) is plugged into a protection frame (1), a power supply circuit can be extended out of the tester body (19) through a through hole (2) on one side of the protection frame (1), then a gear knob (1806) in a fixing mechanism (18) is rotated, the gear knob (1806) drives a threaded shaft (1804) and the gear knob (1806) to move relatively, the threaded shaft (1804) drives a baffle plate (1802) to slide in a fixing groove (1801), when the baffle plate (1802) slides to the edge of the tester body (19), the fixing bolt (1803) is screwed to fix the tester body (19), then the cushion pads (10) are connected into a clamping groove (9) through clamping plates (11) in a clamping way, so that the cushion pads (10) on two ends of the protection frame (1) are connected, and the cushion pads (10) are fixed by using first bolts (12), then, the handle (15) is pushed to enable the handle (15) to be in sliding connection in the sliding grooves (14) on two sides of the broken groove (13) through the convex strips (16), when the handle (15) moves to the bottom of the broken groove (13), the second bolts (17) at two ends of the handle (15) are screwed to fix the handle (15), after the tester body (19) is fixed through the fixing bolts (1803), the device can be moved to other positions by pulling the handle (15), when the device is placed at a specified position and needs to adjust the angle, one end of the bolt rod (23) loosens the extrusion on the rotating frame (22) by unscrewing the first knob (25) on the bolt rod (23), then the rotating frame (22) is rotated to a certain angle according to needs, and then the first knob (25) is screwed to enable the bolt rod (23) to clamp and fix the rotating frame (22), therefore, when the device is placed at a designated position and is vibrated, the shockproof frame (30) enables the second threaded rod (27) to stretch out and draw back at the central position of the connecting plate (26) by extruding the second spring (29) on the second threaded rod (27) through the shockproof frame (30), meanwhile, the two ends of the shockproof frame (30) and the rotating frame (22) slide, so that the device is damped through the shockproof frame (30), the tester body (19) in the device is prevented from being influenced by vibration, the extruded length of the second spring (29) can be adjusted by screwing or unscrewing the second knob (28) on the second threaded rod (27), the damping capacity is adjusted, the mounting or dismounting of the shockproof frame (30) is facilitated, and when the device is placed at the designated position for a long time, because the first spring (24) in the support (20) extrudes the first knob (25) at one end of the bolt rod (23), when the first knob (25) is clamped and fixed, the axial line of the first knob (25) is extruded by the first spring (24), so that the positions of the first knob (25) and the bolt rod (23) are locked, the extrusion force of the bolt rod (23) on the rotating frame (22) is prevented from being reduced due to the looseness of the first knob (25), the angle change of the rotating frame (22) is avoided, when the inside of the protective frame (1) and the outer surface of the tester body (19) need to be cleaned, or the tester body (19) is taken out from the inside of the protective frame (1), the first threaded rod (4) is driven to rotate in the threaded square tube (6) by rotating the hand wheel (5), and because the threaded square tube (6) cannot rotate in the square hole (7), through the screw thread transmission between first threaded rod (4) and screw thread side pipe (6) for screw thread side pipe (6) are flexible in square hole (7), thereby drive push pedal (8) and promote tester body (19), make tester body (19) release from the inside of protection frame (1), and the corresponding clearance instrument of rethread is cleared up the device.
2. The protection device for the network quality and safety tester according to claim 1, wherein: one end of the bolt rod (23) is in a regular hexagonal prism structure, the diameter of the bolt rod (23) is matched with the inner diameter of the first spring (24), and the bolt rod (23) passes through the space between the first spring (24) and the first knob (25) to form a spring structure.
3. The protection device for the network quality and safety tester according to claim 1, wherein: the internal section sizes of the two ends of the shockproof frame (30) are matched with the section size of the rotating frame (22), and the length of the shockproof frame (30) is equal to that of the connecting plate (26).
