[0069] When the device realizes clamping and fixing of the filter 16, only the locking device 6 in contact with the filter 16 is triggered and realizes clamping of the filter 16, and other locking devices 6 remain in the initial state, at this time, the operator can slowly lift the stroke device 11 by holding the holding part 113, in the process, the stroke rod 111 first contacts the locking abutting rod 69 in the locking device 6 in the clamping state, and the locking abutting rod 69 is released from the locking state with the movable lock catch 603, the clamping rod 67 rotates and contacts the outer surface of the stroke rod 111, then continues to slowly lift the stroke device 11, and the clamping rod 67 slowly rotates to the direction close to the telescopic column 61, until the clamping rod 67 contacts the test contact 17 on the filter 16, at this time, the stroke device 11 is stopped, so that the clamping rod 67 can contact the stroke rod 111 and the test contact 17 on the filter 16 at the same time, at this time, the power supply device plug is inserted into the insertion hole 114, the test contact 17 on the filter 16 can be powered and tested through the stroke rod 111 and the clamping rod 67, and the position of the test contact 17 on the filter 16 can be automatically adapted, and the practicability is improved.

[0070] When the test is finished, the operator pulls the plug of the power supply device out of the socket 114, and then pushes the push rod 93 to drive the sliding rod 91 to move, so that the positioning lock catch 92 is dislocated with the locking block 65, thereby releasing the locking state, the first reset spring 64 releases the stored elastic force, so that the locking device 6 used for clamping and fixing the filter 16 moves upward, and then the operator pushes the stroke device 11 downward, so that the stroke rod 111 pushes the clamping rod 67 to rotate outward, and the locking abutment 69 is in contact with and clamped with the movable lock catch 603 again, so that the device returns to the initial state, at this time, the clamping rod 67 is completely unfolded, and the operator can directly take down the filter 16 and replace another filter 16, so that the filter 16 can be quickly disassembled, the use is more convenient, and the practicability of the device is improved.

[0071] In the embodiment, the communication device 12 comprises a bottom bin 121, the bottom bin 121 is provided with a communication seat 122 at the bottom of the inner cavity and close to both sides, and the bottom bin 121 is provided with a spring telescopic seat 123 at the inner cavity and close to the middle, the top of the spring telescopic seat 123 is fixedly installed with a communication plate 124, the bottom of the communication plate 124 is fixedly installed with a communication contact 125 close to both ends, and the communication contact 125 corresponds to the insertion slot at the top of the communication seat 122.

[0073] When the locking device 6 is subjected to the downward pressure of the filter 16, the downward rod 63 moves downward and passes through the through hole 15 at the bottom of the limiting slide rail 5, contacts the top surface of the communication plate 124 and pushes it downward, so that the communication contact 125 is inserted into the inside of the communication seat 122, thereby connecting and activating the two communication seats 122, at this time, the output end of the communication seat 122 is connected with the input end of the power supply device in a signal connection mode, so that the power supply device is in a running state, the power supply device is activated only after the filter 16 is placed, the problem that the power supply device is in a running state for a long time and causes high use cost due to energy consumption increase is avoided, and the practicability of the device is improved.

[0074] The use method of the application is as follows:

[0075] In use, when the filter 16 is placed in contact with the top of the telescopic column 61 and is pressed downward, the telescopic column 61 moves in a vertically downward direction. During this process, the travel rod 111 moves upward and comes into contact with and pushes the locking abutment 69, which is released from the locked state with the movable lock catch 603 during movement of the locking abutment 69. At the same time, the clamping rod 67 rotates toward the telescopic column 61 under the elastic force of the tension spring 605, so that the top end of the clamping rod 67 comes into contact with and clamps the outer surface of the filter 16, thereby achieving fixation. This fixation method can achieve stable fixation of various different specifications of filters 16 and does not require additional adjustment. When the telescopic column 61 moves downward and the top thereof is flush with the top of the housing 1, the locking block 65 is locked with the positioning lock catch 92, preventing the elastic force of the first return spring 64 from lifting the filter 16 and causing instability of fixation, and at the same time, keeping the part in contact with the filter 16 flush with the top of the housing 1. After the device achieves clamping and fixation of the filter 16, only the locking device 6 in contact with the filter 16 is triggered and achieves clamping of the filter 16, while the other locking devices 6 remain in the initial state. At this time, the operator can slowly lift the travel device 11 by hand holding the gripping portion 113. During this process, the travel rod 111 first comes into contact with the locking abutment 69 of the locking device 6 in the clamped state and releases the locking state of the locking abutment 69 and the movable lock catch 603. The clamping rod 67 rotates and comes into contact with the outer surface of the travel rod 111. Then, the travel device 11 is continuously slowly lifted, and at the same time, the clamping rod 67 slowly rotates toward the telescopic column 61 until the clamping rod 67 comes into contact with the test contact 17 on the filter 16. At this time, the travel device 11 is stopped, so that the clamping rod 67 can come into contact with the travel rod 111 and the test contact 17 on the filter 16 at the same time. At this time, the power supply equipment plug is inserted into the jack 114, which can achieve power supply to and testing of the test contact 17 of the filter 16 by the travel rod 111 and the clamping rod 67. This testing method can automatically adapt to the position of the test contact 17 of the filter 16. Since the top of the clamping rod 67 is provided with the gasket 604, it plays a role in preventing slipping when coming into contact with and clamping the outer surface of the filter 16. At the same time, it also plays a role in insulation, avoiding the current passing through the clamping rod 67 to break through the housing of the filter 16 when the travel rod 111 is in a power-on state. Moreover, the clamping rod 67 that is not in contact with the housing of the filter 16 and the test contact 17 and is in a relative position will not come into contact with each other due to being blocked by the travel rod 111.When the locking device 6 is pressed down by the filter 16, the lower pressing rod 63 moves down through the through hole 15 at the bottom of the limiting slide rail 5, contacts the top surface of the communication plate 124 and pushes it down, so that the communication contact 125 is inserted into the inside of the communication seat 122, thereby making the two communication seats 122 connected and activated, at this time, the output end of the communication seat 122 is connected with the input end of the power supply device through signal connection, so that the power supply device is in the running state, which realizes that the power supply device is activated only after the filter 16 is placed. After the test is completed, the operator pulls out the plug of the power supply device from the plug hole 114, and then pushes the push rod 93 to drive the sliding rod 91 to move, so that the positioning lock 92 is dislocated with the locking block 65, thereby releasing the locking state, the first reset spring 64 releases the stored elastic force, so that the locking device 6 used for clamping and fixing the filter 16 moves up, then the downward pushing stroke device 11 is pushed, so that the stroke rod 111 pushes the clamping rod 67 to rotate outward, and the locking rod 69 is in contact with the movable lock 603 again and is clamped and fixed, thereby restoring the initial state of the device, at this time, the clamping rod 67 is completely unfolded, and the operator can directly take down the filter 16 and replace another filter 16, thereby realizing quick disassembly and being more convenient to use.
